Puncture Repair & Wheel Changing

9. Drive immediately to a service station and inflate the tyre to

the correct pressure (see ‘TYRE PRESSURES’, page 191). If

the required pressure cannot be reached, then the tyre is too

severely damaged and you should seek assistance from the

breakdown services. DO NOT DRIVE THE CAR!

10. If the correct tyre pressure was achieved, continue driving.

Drive carefully and do not exceed 80 km/h. At the earliest

opportunity, have the tyre repaired or replaced by a dealer or

tyre specialist and replace the used canister of tyre sealant.

Always inform the tyre repairer that tyre sealant has been

used. If the tyre is to be subsequently deflated, only do so in a

well ventilated area.

When the sealant stops flowing through the tube, release the

button and unscrew the tube from the valve.

NOTE: If tyre sealant comes into contact with the car's paintwork,

wash the area with water as soon as possible.

If the wheel rim is clear of the ground, drive the car

IMMEDIATELY for approximately 6 km to spread the

sealant evenly inside the tyre. Drive gently and DO NOT

exceed 45 km/h. If the wheel rim does not lift from the

ground, DO NOT drive the car; seek assistance from the

breakdown services.

CHANGING A WHEEL

Accessing the spare wheel and tools - Saloon models

If possible, choose a safe place to stop away from the main

thoroughfare. Always ask your passengers to get out of the car and

wait in a safe area away from other traffic.

Switch on the hazard warning lights and use a warning triangle (if

available) to alert other road users.

Before changing a wheel, ensure the front wheels are in the

straight ahead position, apply the handbrake and engage 1st gear

(select ‘P’ for automatic gearbox cars). Observe the following

precautions:

• Ensure the jack is positioned on firm, level ground; NEVER on

soft ground, or over metal gratings or manhole covers. DO

NOT place additional material between the jack and the

ground, this may jeopardise the safety of the jacking operation.

• If jacking on a slope is essential, place chocks at the front and

rear of the wheel diagonally opposite the one to be removed.

• NEVER jack the car with passengers inside or with a caravan

or trailer connected!

NOTE: The stowage compartment set into the inside of the tailgate on

Tourer models is designed to accommodate the accessory warning triangle

available from MG Rover dealers.

HB0495

Raise the carpeted floor panel, using the lifting handle (set into the

floor) and hook the handle over the boot drain channel.

replace the punctured front wheel.

227

Puncture Repair & Wheel Changing

Using the wheel chock (Tourer models only)

On Tourer models, to ensure adequate stability, even on level

ground, it is essential to chock one of the road wheels before

raising the car from the ground.

Before positioning the chock, it must be assembled, as follows:

1. Pull the two halves of the chock slightly apart.

2. Rotate one half of the chock 180°.

3. Push the two halves back together.

Always chock the wheel diagonally opposite the one to be

removed - chocking the front of a front wheel, or the back of a

rear wheel, as shown.

Always check the tyre pressure after changing a wheel, and

have the tightness of the wheel bolts checked by a dealer as soon

as possible!

The following precautions must be observed when the

space saver spare wheel is in use:

•

The space saver spare wheel is for temporary use only. It must be

replaced by the normal sized wheel as soon as possible.

•

Only one space saver wheel is to be used on the car at any one

time.

•

A maximum speed of 80 km/h must be observed.

The main beams are powered by Halogen bulbs, which can be

replaced by the owner, provided the bulb handling precautions

shown at the start of the bulb replacement section are observed.

1. Remove the rubber cover from the rear of the headlight.

2. Twist the bulb (and bulb holder) one eighth of a turn anti-

clockwise to release from the light unit.

3. Release the clips on either side of the electrical connector (see

inset) and detach from the bulb. When refitting, note that the

connector fits one way round only.

Replacement of the bulb is a reversal of the above process.

Sidelight

Replacement bulb: 5 watt.

On cars equipped with Xenon headlights, the sidelight bulbs are

positioned inside the inboard headlight units. The sidelight bulb

holder is immediately below the main beam headlight bulb (see

inset in bottom corner of illustration).

3. Pull the bulb from the bulb holder.

Replacement of the bulb is a reversal of the removal process.

However, the following points should be noted:

• It is essential that the bulb is refitted correctly. Note the square

tab on the bulb mounting plate and its relationship with the tab

projecting from the mounting plate on the bulb holder

(arrowed in lower inset). The bulb MUST be fitted the correct

way round, with both mounting plates in full contact.

• Similarly, the bulb holder assembly must be fitted into the light

unit the correct way round in order for the bayonet pins to

engage. Present the bulb holder assembly to the light unit with

the square tab on the bulb mounting plate (referred to above)

pointing towards the ground.

Replacing the access panel

Clip the protrusion at the top of the access panel into the aperture

3. Unhook the wire securing clip.

4. Remove the bulb.

When replacing the bulb, the following tips will make the job

easier.

• Always remove the electrical connector BEFORE unhooking

the wire securing clip.

• Examine the illustration carefully to see how the wire securing

clip (3) works.

• Before replacing the electrical connector, refer to the

illustration to check which way round the connector needs to

be to enable it to fit onto the spade-type contacts on the bulb.

Replacement of the bulb is a reversal of the removal process.

NOTE: When replacing the bulb, ensure the squared tab on the bulb

mounting plate (4) is vertically aligned. Insert the new bulb fully and hold

in this position while fitting the wire securing clip, and before attaching the

electrical connector.
