The instruments and driving controls are situated so they can conveniently be seen and used, thus allowing maximum attention to be given to the road ahead. They are all illustrated and described on the following pages. The numbers in brackets after each sub-heading refer to this illustration.
The design of the petrol/oil level indicator and water temperature indicator ensures that the needle does not fluctuate, but there is a time lag of a few seconds, before they register, after the ignition has been switched on.

Ignition and starter switch (6)
The switch at the left-hand bottom of the instrument panel combines ignition and starting control. Turn the key clockwise for 'on', then push in and continue in a clockwise direction against a spring to start the engine. Immediately the engine fires release the key, it will automatically return to the ignition 'on' position. If the key is turned anti-clockwise the radio and fan can be used with ignition 'off'.
The key is removable and also serves for the front door lock; the other key on the ring locks the luggage boot and glove box lid.
With the ignition switched 'off',only the following electrical equipment can be used:
Driving lights (head, side and tail), interior lights, horns and clock.

Ignition warning light (13)
The red warning light, which is the lower of the grouped warning lights in the centre of the instrument panel, appea/rs when the dynamo fails to charge or the dynamo charging rate is low. It will glow when the ignition is switched on and the engine is stationary or running slowly and will go out when the engine speed rises.

Oil pressure warning light (15)
The green warning light, which is the right-hand upper one of the group, glows when the engine oil pressure drops below 6 to 10 lblsq.in. (0,4 to 0,7 kg/cm squared). It will light up when the engine is stationary and fade out when the engine starts and the oil pressure has built up to exceed this figure.
The light may flicker when the engine is running at idling speed; provided it fades out immediately the engine is speeded up, the oil pressure can be considered satisfactory.
Should the warning light appear at any time when the engine is running above idling speed, stop the engine immediately and investigate the cause; the most likely is that of low oil level in the sump.
To guard against bulb failure in the oil pressure and ignition warning lights, a check should be made that the bulbs glow each time the ignition is switched on.

Cold start control warning light (12)
The appearance of the round amber warning light, which is the left-hand upper of the group, will indicate that the control has been left out inadvertently and must be pushed in at once.
Like all mechanical devices, the mixture control warning system is not completely fool-proof and the responsibility for pushing in the cold start control rests with the driver. Suspected bulb failure may be confirmed by pulling out the cold start control momentarily when the engine is hot, when the bulb should be illuminated.
Should a warning light bulb burn out it should be replaced at the earliest opportunity.

Cold start control (32)
Marked 'Cold Start' and mounted on the centre control panel to the right of the heater controls.

It provides a normal mixture when pushed right in, then as the control is pulled out, the engine idling speed is gradually increased; in addition, during the second part of the control movement, the mixture is progressively strengthened until, with the knob right out, a very rich mixture is obtained for starting from cold. By turning the knob slightly, the control can be locked in any position.
When the engine has started, the control must be returned to the normal position as soon as possible, consistent with even running.
See starting procedure for full details.

Ammeter (18)
The ammeter, in the multiple gauge, indicates the charging or discharging rate of the battery.
An automatic control regulates the charging rate.
When starting from cold, the charge rate will rise to a steady maximum, remain constant for a short while and then fall as the battery again becomes fully charged.

Fuel and oil level indicator (17)
The fuel level indicator, in the multiple instrument, only operates with the ignition 'on, The instrument shows the fuel level.
The fuel level indicator is not a precision instrument and cannot be used to determine accurate consumption figures.
This gauge will also indicate the approximate engine oil level when the centre knob on the right-hand side of the instrument panel is moved outwards.

Water temperature indicator (16)
This instrument, in the multiple gauge, indicates the engine working temperature.
It is marked C (cold) on a blue band, N (normal) on a white band E871 and H (hot) on a red band.

Under normal running conditions
the needle should be in the white band marked N.

Ventilation, heating and cooling (25, 26 and 27)
The car has been equipped with a specially designed ventilating system. In cold weather air entering the car for ventilation can be suitably heated and used also to demist or defrost the windscreen.
A powerful heater unit is used to heat air entering from outside the car via the air scoop below the windscreen.
The controls are mounted in a quadrant below the facia panel. They are clearly labelled, and by suitable combination of their settings the system will meet varying requirements, referred to overleaf.
The large fresh air knob at the top of the control has three
positions:
(a) In centre, all fresh air shut off. Heating by recirculation can still be effected.
(b) Move to the right, heating open. This, in conjunction with the levers below, gives heat control to car and windscreen.
(c) Move to the left, cooling open, thus allowing cool air to enter the car during hot weather.

Operation of ventilation, heating and cooling system
Normal driving conditions:
Set fresh air lever to 'heating open'.
Set screen control to 'demist' and move heat control to the right until the desired temperature is obtained. For increased output switch on heater fan by pulling knob outwards.
To meet other conditions typical settings of the controls, which are progressive in their action, are given below:
Defrost windscreen:
Set fresh air lever to 'heating open'. Set screen control to defrost and move heat control fully to the right.
For increased output switch on the heater fan.
Maximum heat:
Set fresh air lever to 'heating open'. Set heat control fully to the right and move screen control to approximately mid-way between 'defrost' and 'demist'.
This position is positive and the lever will 'click' into it.
For maximum output switch on fan.

Demisting, warm weather:
Set fresh air lever to 'heating open' and move screen control to 'demist'.
Set heat control to 'off'. For maximum output switch on fan.
Main light and parking switch (8)
The side, tail, parking and headlamps are controlled by the uppermost switch on the left-hand side of the instrument panel.
Switch in centre (off) position:
All lamps extinguished.
Switch in L.H. (side) position:
Side, tail and rear number plate lamp on; also headlamps, depending on the position of the headlamp switch situated on the steering column.
Switch in R.H. (park) position:
R.H.D. models: right-hand side and tail light on.
L.H.D. models: left-hand side and tail light on.

Headlamp switch (42)
With the main switch in the 'side' position, the headlamps will be either 'on' or 'off', depending on the position of the main lamp switch on the steering column.
On North American cars, the sidelamps are extinguished when the headlamps are switched on.

Headlamp dipper switch (31)

The dipper switch, which is situated to the left of the clutch pedal, replaces the primary filaments in both headlamps by secondary filaments directed downwards.

Main beam warning light (10)
The small blue warning light is positioned at the bottom centre of the speedometer. It glows when the primary headlamp beams are in use; its purpose is to remind the driver to switch off or dip the headlamps on entering a brightly-lit area, or when approaching other traffic.

Instrument panel light switch (21)
The rheostat switch, which is at the top right-hand side of the panel, is only operative when the side lights are on; maximum brightness is obtained by moving the switch knob slightly outwards.
The panel lights can then be progressively dimmed by continuing the outward movement of the knob.

Windscreen wiper switch (19)
Also washer switch on 110 models.
The switch controlling the wipers is at the lower right-hand side of the panel. When the switch is returned to the 'off' position, the wiper blades are automatically parked off the windscreen.

On 110 models the windscreen wiper switch is also used to operate the windscreen washer. To wash the windscreen push in the knob and hold in as necessary; release knob to stop spray. The washer can be operated with the windscreen wiper switch in the 'on' or 'off' position.

Windscreen washer (19) (30)
95 models. The windscreen washer is operated by the small knob situated to the left of the steering column on R.H.D. models and to the left of the dipper switch on L.H.D. models.

To wash the windscreen~ switch on the windscreen wipers and press the knob repeatedly with the foot until the windscreen is clean, when the windscreen wipers should be switched off.
110 models. The windscreen washer is operated by the windscreen wiper switch situated at the lower right-hand side of the instrument panel. See above.
If possible, use soft or distilled water on all models.
In cold weather, to prevent freezing of the water, the container, mounted under the bonnet on the wing valance, should be filled with 0.125 pint (0,7 dl) of methylated spirit.

Speedometer (11)
The speedometer incorporates total and trip mileage indicators. The trip reading can be turned back to zero by pushing in and rotating the button protruding beneath the instrument panel.
The maximum recommended speeds in each gear are indicated by appropriate yellow figures.

Direction indicator arrows (9)
The green direction indicator arrows at the bottom of the speedometer flash either R.H. or depending on direction of turn, in sympathy with the indicator bulbs.
The flasher unit, mounted behind the instrument panel, is audible in operation.
Should either a front or rear indicator bulb fail, the remaining indicator will continue to flash and both indicator arrows will flash rapidly; the flasher unit will not be heard.

Direction indicator switch (43)
Is the upper lever on the side of the steering column.
On right-hand drive models, to indicate a turn to the right, press the control downwards; for a left turn, upwards.
Left-hand drive models: to indicate a turn to the right, press the control upwards; for a left turn, press downwards.

The direction indicator switch is self-cancelling; on a slight bend the control may not return, in which case is must be cancelled by hand.

Fuel reserve switch (7)
A dual fuel pump is fitted and the switch on the left centre of the instrument panel operates the secondary pump, thus drawing on the reserve supply.
Move lever outwards when it is desired to draw on the reserve supply.
The secondary pump should be used once a week for a few miles' driving to ensure that it is kept in good condition. Do not forget to turn switch to 'Main' after this operation, or when the fuel reserve has been used in the tank has been replenished after the normal manner. Reserve supply is approximately 1 to 1.5 gallons (4 to 7 litres). Total capacity is 1l.5 Imperial gallons (52 litres).

Clock (4)
The electric clock is mounted in the centre of the facia rail; to adjust the hands push in the knob in the centre of the instrument and turn in the required direction.
Interior lights
The front interior light is switched on automatically when either door is opened and extinguished when the door is closed.
Each rear interior light is automatically switched on when the appropriate rear door is opened and extinguished when the door is closed.

The lights can be controlled manually as follows:
Front light by means of small switch behind the facia rail. Rear light by means of switch on the centre door pillar.

Fog lamps, optional equipment (33)
Fog lamps can be mounted on the front apron; they are controlled by switches mounted on a bracket fitted to the centre control panel.
The fog lamps can only be used when the main switch is on.
Bulb replacement
For bulb replacement on instrument panel and all lights, interior and exterior, see Part Two of this book.

Radio, optional equipment
Provision is made for fitting radio on the facia board in place of the centre glove box locker.
Operating instructions are supplied with the set.

Heated backlight (Optional Equipment) (24)
The heated backlight which is available as an optional equipment, is controlled by a push-pull switch on the left-hand side of the centre control panel. A white warning light is incorporated in the knob to indicate that the backlight heating element is switched on.
It can also be used with the ignition switch in the auxiliary position.
