STEERING GEAR.
Burman-Douglas re-circulating ball pattern (see Page 4l)

HEATER-DEMISTER.
Clayton-Dewandre type. Air drawn from the front of the car is heated by water circulation from the engine. Its volume is controlled by a fan and manually operated shutters. The water supply may be cut off by a valve at the front of the engine at the left-hand side (see Page 67, and Figs. 8 and 10):

CONTROLS AND INSTRUMENTS

The principal controls and instruments are illustrated on Page 18 and their use in. most instances will be obvious upon examination.

FOOTPEDALS.
The three foot pedals are normal in position and operation.

MIXTURE CONTROL.
The mixture control is situated on the right of the facia board (Fig. 2). It is marked "COLD START" and its operation and also the action of the MIXTURE CONTROL WARNING LIGHT are fully described on Page 16. This light is amber in colour and is located on the instrument panel to the right of the ignition switch.

IGNITION SWITCH.
This takes the form of- a barrel lock controlled by a small yale-type key, situated in the centre of the instrument panel. When the ignition is switched off, the key can be withdrawn.

STARTER SWITCH.
This is located immediately above the ignition switch.

CAR HEATER SWITCH.
This is positioned at the left-hand lower corner of the facia board (Fig. 2). For details of car heater operation see Page 67.

PETROL RESERVE SWITCH.
See Page 7.

WINDSCREEN WIPER SWITCH.
The switch controlling the windscreen wipers is of the push-pull type and. operates both wipers simultaneously. (Fig. 2).

LAMP SWITCH.
The side and headlamps are controlled by a switch on the steering column, the rotary knob being turned until the white pointer is opposite the required position on the switch body, i.e., "0" (OFF), "5" (SIDE AND TAIL) or "H" (SIDE, TAIL AND HEAD).
The headlamp dipper-switch is located on the steering wheel boss, and its action differs on home and export models.

LAMP DIPPERSWITCH.
HOME MODELS: The dipper switch extinguishes the right-hand side headlamp and replaces the primary filament in the other lamp by a secondary "out-of-focus" filament.

EXPORT MODELS These have dual-filament headlamps. When the dipper-switch is operated, the primary (filaments are extinguished ~and the secondary "out-of-focus" filaments in both lamps come into operation.

FOG LAMP SWITCH.
The central fog-light is operated from a switch on the left-hand side of the facia board.

INSTRUMENT PANEL LIGHT SWITCH.
The rheostat switch controlling the panel lights is situated on the right of the instrument panel. (Fig. 2). It is only operative when the ignition is "on."

INTERIOR LIGHT SWITCH.
The interior (roof) light is controlled by a rotary switch to the left of the, ignition switch. (Fig. 2).

HORN BUTTON.
The twin horns are operated by means of the push-button in the centre of the steering wheel boss.

TRAFFICATOR CONTROL. (Fig. 2).
RIGHT-HAND DRIVE MODELS: To indicate a turn to the right, press the control on the right of the steering column downwards; for a left turn, press upwards.
LEFT-HAND DRIVE MODELS : To indicate a - turn to the right, press the control on the left of the steering column upwards for a left turn, press downwards.
The control will automatically return to the OFF position after the turn has been completed.

FREE WHEEL CONTROL.
The freewheel control is situated in the centre of the facia board (Fig. 2).
When this control is turned in a clockwise direction as far as possible, the freewheel is in operation, whilst turning the control as far as possible in an anti-clockwise direction renders the freewheel inoperative.

Detailed instructions for using the freewheel are given on Page 23 and these should be consulted before attempting to operate the control whilst the car is moving.
