FOREWORD

This Handbook introduces you to your British Leyland car. Your car is built to a high standard of quality and reliability and with good driving, correct car care and regular maintenance should give you carefree and economical motoring.

The introductory pages cover the operation and function of the controls, switches and general equipment fitted.

The main part of the Handbook gives detailed information on jacking, wheel changing, bulb renewal, lubrication and the servicing procedure of components.

Regular maintenance at the recommended intervals is essential to maintain your car at the original standard of efficiency and you will find our detailed recommendations under 'MAINTENANCE SUMMARY'. Those items which require specialized equipment should be carried out by a Distributor or Dealer. Refer to the 'GENERAL DATA' for information required during servicing and the dayto-day running of the vehicle such as tyre pressures, oil capacities, etc.

Our Distributors and Dealers are trained and available to service your car for you, and details of our maintenance scheme are included in your Passport Service. Look for the Leycare Service sign.

References to right- or left-hand are made as if the car is being viewed from the rear.

The gear positions are indicated on the lever knob. To engage reverse gear move the lever to the left in the neutral position until resistance is felt, apply further side pressure to overcome the resistance and then pull the lever back to engage the gear. The reverse lights operate autoniatically when reverse is selected with the ignition switched on.

Synchromesh engagement is

prokidcd on all forward gears.

The manual selection positions are indicated on the selector lever quadrant plate.

Full driving instructions for cars fitted with a~~toniatic transmission are given on page

The hand brake is of the pull-LIP lever type, operating mechanically on the rear

wheels only. To release the hand brake pull the lever up 4ightly, depress the button on the end of the lever and push the lever down.

The pedals are arranged in the conventional positions. The brake pedal operates the brake hydraulic system and applies

the

brakes on all four wheels, also bringing the stop uarning lights into operation when the ignition is switched on.

To enrich the fuel air mixture and assist starting when the engine is cold, pull out the knob and turn a quarter of a turn clockwise to lock the control in the

position selected. To release the control turn it in an anti-clockwise direction

and push it inwards.

DO NOT MOVE the control in or out whilst it is in the locked position. Notes

on setting the control are given on page

fitted in the tachometer serves the dual purpose of reminding the driver to switch off the ignition and of acting as a no-charge indicator.*

Early cars

The ignition and starter are both controlled by a single switch operated by a

removable key. To switch on the ignition insert the key and turn it in a clockwise

direction until a slight resistance is felt. Further movement in the same direction

operates the starter motor. Release the key immediately the engine starts.

To operate the auxiliary electrical services when the car is parked without the necessity of loading the ignition circuit or starting the engine, turn the ignition

key in an anti-clockwise direction. The heater blower motor, windscreen wipers,

and the radio may then be operated by switching on the appropriate switch. The key can only be withdrawn when the switch is in the 'off' position.

are sitting in a normal relaxed position when making the test. The retarding

effect of braking must not be anticipated. If a belt fails to lock, consult your

Starting

The octane number of a motor fuel is an indication given by the fuel technicians

of its knock resistance (pinking). High-octane fuels have been produced to improve the efficiency of engines by allowing them to operate on high compression ratios, resulting in better fuel economy and greater power. Fuels with an octane rating of below not suitable. Should it be necessary to use a fuel with a lower octane number,

the car must be used very carefully until the correct fuel can be obtained.

When filling up with fuel avoid filling the tank until fuel is visible in the filler

intake tube. Should this be done and the car left in the sun, there will be a considerable risk of fuel leakage due to expansion, and consequent danger from exposed fuel. If inadvertently overfilled and the car is to be parked, take care

to park it in the shade with the filler intake as high as possible.

The fuel tank is vented through the filler cap.

filler cap to fit this model.

Check that the gear lever is in the neutral position. If the engine is cold, pull out the mixture control (choke) and lock it in the desired

position by turning the control knob a quarter of a turn clockwise. In extremely cold conditions it may be necessary to pull the control out to its fullest extent.

Switch on the ignition, check that the ignition warning light glows and that the fuel gauge registers, then operate the starter.

As soon as the engine starts, release the ignition key and warm up the engine at a fairly fast speed (see 'Warming up'). Check that the oil pressure gauge is registering and that the ignition warning light has gone out. Unlock the mixture control (choke) and push it in completely as soon as the engine will run evenly without its use.

Starter

Do not operate the starter for longer than five to six seconds. To prevent damage the starter cannot be operated while the engine is running.

If the engine fails to start, the ignition key must be returned to the 'off' position before the starter can be operated again.

If after a reasonable number of attempts the engine should fail to start, switch off the ignition and investigate the cause. Continued use of the starter when the engine will not start not only discharges the battery but may also damage the starter.
