to release any pressure. When pressure has
been released, carry on unscrewing the cap
and remove it.
9Top-up to the MAX mark with the specified
coolant (see illustration).In an emergency
plain water is better than nothing, but
remember that it is diluting the proper coolant.
Do not add cold water to an overheated
engine whilst it is still hot.
10Refit the expansion tank cap securely
when the level is correct. With a sealed type
cooling system like this, the addition of
coolant should only be necessary at very
infrequent intervals. If frequent topping-up is
required, it is likely there is a leak in the
system. Check the radiator, all hoses and joint
faces for any sign of staining or actual
wetness, and rectify as necessary. If no leaks
can be found, it is advisable to have the
pressure cap and the entire system pressure-
tested by a dealer or suitably-equipped
garage, as this will often show up a small leak
not previously apparent.
Brake fluid
Be sure to use only the specified brake
hydraulic fluid, since mixing different types of
fluid can cause damage to the system. See
“Lubricants, fluids and capacities”at the
beginning of this Chapter. When adding fluid,
it is a good idea to inspect the reservoir for
contamination. The system should be drained
and refilled if deposits, dirt particles or
contamination are seen in the fluid.
11Check the brake fluid level as follows.
12With the vehicle parked on level ground
and the ignition switched off, pump the brake
pedal at least 20 times or until the pedal feels
hard.
13Open the bonnet. Switch on the ignition:
the hydraulic unit pump will be heard running.
Wait until the pump stops, then switch off the
ignition.
14The fluid level in the reservoir should now
be between the MAX and MIN marks. If
topping-up is necessary, unplug the electrical
connectors from the cap, then unscrew and
remove it (see illustration).Catch the
hydraulic fluid which will drip off the level
sensor with a piece of rag.
15Top-up with fresh brake fluid of the
specified type (see illustration).Do not
overfill. Refit and reconnect the reservoir cap
immediately.16The fluid level in the reservoir will drop
slightly as the brake pads wear down during
normal operation. If the reservoir requires
repeated replenishment to maintain the proper
level, this is an indication of a hydraulic leak
somewhere in the system, which should be
investigated immediately.
Washer fluid
17When topping-up the windscreen or rear
screen washer fluid reservoir, a screenwash
additive should be added in the quantities
recommended on the bottle.
1On later models tyres may have tread wear
safety bands, which will appear when the
tread depth reaches approximately 1.6 mm.
Otherwise, tread wear can be monitored with a
simple, inexpensive device known as a tread
depth indicator gauge (see illustration).
2Wheels and tyres should give no real
problems in use, provided that a close eye is
kept on them with regard to excessive wear or
damage. To this end, the following points
should be noted.
3Ensure that the tyre pressures are checked
regularly and maintained correctly (see
illustration). Checking should be carried out
with the tyres cold, not immediately after the
vehicle has been in use. If the pressures are
checked with the tyres hot, an apparently-high
reading will be obtained, owing to heat
expansion. Under no circumstancesshould
an attempt be made to reduce the pressures
to the quoted cold reading in this instance, or
effective under-inflation will result.
4Note any abnormal tread wear (see
illustration). Tread pattern irregularities such
as feathering, flat spots, and more wear on
one side than the other, are indications of front
wheel alignment and/or balance problems. If
any of these conditions are noted, they should
be rectified as soon as possible.
5Under-inflation will cause overheating of the
tyre, owing to excessive flexing of the casing,
and the tread will not sit correctly on the road
surface. This will cause excessive wear, not to
mention the danger of sudden tyre failure due
to heat build-up.

Warning: Brake hydraulic fluid
can harm your eyes and damage
painted surfaces, so use extreme
caution when handling and
pouring it. Do not use fluid that has been
standing open for some time, as it absorbs
moisture from the air. Excess moisture can
cause a dangerous loss of braking
effectiveness.If any brake fluid gets onto
paintwork, wash it off
immediately with clean water.

6Over-inflation will cause rapid wear of the
centre part of the tyre tread, coupled with
reduced adhesion, harsher ride, and the
danger of shock damage occurring in the tyre
casing.
7Regularly check the tyres for damage in the
form of cuts or bulges, especially in the
sidewalls. Remove any nails or stones
embedded in the tread before they penetrate the
tyre to cause deflation. If removal of a nail does
reveal that the tyre has been punctured, refit the
nail so that its point of penetration is marked.
Then immediately change the wheel, and have
the tyre repaired by a tyre dealer. Do not drive on
a tyre in such a condition. If in any doubt as to
the possible consequences of any damage
found, consult your local tyre dealer for advice.
8Periodically remove the wheels, and clean
any dirt or mud from the inside and outside
surfaces. Examine the wheel rims for signs of
rusting, corrosion or other damage. Light alloy
wheels are easily damaged by “kerbing” whilst
parking, and similarly steel wheels may
become dented or buckled. Renewal of the
wheel is very often the only course of remedial
action possible.
9The balance of each wheel and tyre
assembly should be maintained to avoid
excessive wear, not only to the tyres but also
to the steering and suspension components.
Wheel imbalance is normally signified by
vibration through the vehicle’s bodyshell,
although in many cases it is particularly
noticeable through the steering wheel.
Conversely, it should be noted that wear ordamage in suspension or steering
components may cause excessive tyre wear.
Out-of-round or out-of-true tyres, damaged
wheels, and wheel bearing wear also fall into
this category. Balancing will not usually cure
vibration caused by such wear.
10Wheel balancing may be carried out with
the wheel either on or off the vehicle. If
balanced on the vehicle, ensure that the
wheel-to-hub relationship is marked in some
way prior to subsequent wheel removal, so
that it may be refitted in its original position.
11General tyre wear is influenced to a large
degree by driving style - harsh braking and
acceleration, or fast cornering, will all produce
more rapid tyre wear. Interchanging of tyres
may result in more even wear. However, if this
is completely effective, the added expense is
incurred of replacing all four tyres at once,
which may prove financially-restrictive for
many owners.
12Front tyres may wear unevenly as a result
of wheel misalignment. The front wheels
should always be correctly aligned according
to the settings specified by the vehicle
manufacturer.
13Legal restrictions apply to many aspects
of tyre fitting and usage, and in the UK this
information is contained in the Motor Vehicle
Construction and Use Regulations. It is
suggested that a copy of these regulations is
obtained from your local police, if in doubt as
to current legal requirements with regard to
tyre type and condition, minimum tread depth,
etc.Check the operation of all the electrical
equipment, ie. lights, direction indicators,
horn, washers, etc. Refer to the appropriate
Sections of Chapter 13 for details if any of the
circuits are found to be inoperative.
Visually check all accessible wiring
connectors, harnesses and retaining clips for
security, and for signs of chafing or damage.
Rectify any faults found.
Caution: Before carrying out any work on the
vehicle battery, read through the precautions
given in “Safety first!” at the beginning of this
manual.
1The battery fitted as original equipment is
“maintenance-free”, and requires no
maintenance apart from having the case kept
clean, and the terminals clean and tight.
2If a “traditional” type battery is fitted as a
replacement, remove the old cell covers and
check that the plate separators in each cell are
covered by approximately 6 mm (0.25 in) of
electrolyte. If the battery case is translucent,
the cell covers need not be removed to check
the level. Top-up if necessary with distilled or
de-ionized water; do not overfill, and mop up
any spillage at once(see illustration).
