There are some very simple checks which
need only take a few minutes to carry out, but
which could save you a lot of inconvenience
and expense.
These "Weekly checks" require no great skill
or special tools, and the small amount of time
they take to perform could prove to be very
well spent, for example;MKeeping an eye on tyre condition and
pressures, will not only help to stop them
wearing out prematurely, but could also save
your life.
MMany breakdowns are caused by electrical
problems. Battery-related faults are
particularly common, and a quick check on a
regular basis will often prevent the majority of
these.MIf your car develops a brake fluid leak, the
first time you might know about it is when your
brakes don't work properly. Checking the level
regularly will give advance warning of this kind
of problem.
MIf the oil or coolant levels run low, the cost
of repairing any engine damage will be far
greater than fixing the leak, for example.

Coolant level Engine oil level
Before you start
4Make sure that your car is on level ground.
4Check the oil level before the car is driven,
or at least 5 minutes after the engine has been
switched off.
The correct oil
Modern engines place great demands on their
oil. It is very important that the correct oil for
your car is used (See “Lubricants and Fluids”).
Car Care
l If you have to add oil frequently, you should
check whether you have any oil leaks. Place
some clean paper under the car overnight,
and check for stains in the morning. If there
are no leaks, the engine may be burning oil
(see “Fault Finding”).
lAlways maintain the level between the
upper and lower dipstick marks (see photo 3).
If the level is too low severe engine damage
may occur. Oil seal failure may result if the
engine is overfilled by adding too much oil.

Using a clean rag or paper towel remove
all oil from the dipstick. Insert the clean
dipstick into the tube as far as it will go, then
withdraw it again.
Add a mixture of water and antifreeze
through the expansion tank filler neck
until the coolant reaches the “MAX” level
mark. Refit the cap, turning it clockwise as far
as it will go until it is secure.
If topping-up is necessary, wait until the
engine is cold. Slowly turn the expansion
tank cap anti-clockwise to relieve the system
pressure. Once any pressure is released, turn
the cap anti-clockwise unti it can be lifted off.The coolant level varies with the
temperature of the engine. When the
engine is cold, the coolant level should be at
the “MAX” mark. When the engine is hot, the
level may rise slightly above this mark.
Note the oil level on the end of the
dipstick, which should be between the
upper (“MAX”) mark and lower (“MIN”) mark.
Approximately 1.0 litre of oil will raise the level
from the lower mark to the upper mark.Oil is added through the filler cap.
Unscrew the cap and top-up the level; a
funnel may help to reduce spillage . Add the
oil slowly, checking the level on the dipstick
frequently. Avoid overfilling (see “Car Care”).
On some models, the dipstick is brightly
coloured for easy identification. Refer to
the photos on pages 0•10 and 0•11 for the
exact location for each engine type12

Warning: DO NOT attempt to
remove the expansion tank
pressure cap when the engine
is hot, as there is a very great
risk of scalding. Do not leave
open containers of coolant
about, as it is poisonous.Car Care
lWith a sealed-type cooling system, adding
coolant should not be necessary on a regular
basis. If frequent topping-up is required, it is
likely there is a leak. Check the radiator, all
hoses and joint faces for signs of staining or
wetness, and rectify as necessary.lIt is important that antifreeze is used in the
cooling system all year round, not just during
the winter months. Don’t top-up with water
alone, as the antifreeze will become too
diluted.
If the oil is checked
immediately after driving the
vehicle, some of the oil will
remain in the upper engine
components, resulting in an inaccurate
reading on the dipstick!

Before you start:
4Park the vehicle on level ground.
4Set the steering wheel pointing straight-
ahead.
4The system should be at operating
temperature and the engine should be
turned off.
Safety First:
lThe need for frequent topping-up indicates
a leak, which should be investigated
immediately.
Top-up if necessary with clean fluid of
the specified typeIf the level is checked
cold, use the “MIN” or “FULL COLD” mark.
Recheck the level at operating temperature.
The fluid level should be up to the
“MAX” or upper “HOT” markThe power steering fluid reservoir is
located next to the coolant expansion
tank. Clean around the filler cap and then
remove it should topping up be required.123
For the check to be accurate
the steering must not be
turned once the engine has
been stopped.

Electrical system
To replace a blown fuse, simply pull it out.
Fit a new fuse of the same rating,
available from car accessory shops.
It is important that you find the reason that the
fuse blew - a checking procedure is given in
Chapter 13.If more than one indicator light or
headlight has failed it is likely that either a
fuse has blown or that there is a fault in the
circuit (refer to“Electrical fault-finding”in
Chapter 13).
The fuses are mounted in a box in the engine
compartment on the right-hand side of the
bulkhead. Remove the loose cover (and spring
clip if fitted), pulling the plastic clip, and
removing the plastic cover.If a single indicator light, brake light or
headlight has failed it is likely that a bulb
has blown and will need to be replaced. Refer
to Chapter 12 for details.
If both brake lights have failed, it is possible
that the brake light switch above the brake
pedal needs adjusting. This simple operation
is described in Chapter 9.1
If you need to check your
brake lights and indicators
unaided, back up to a wall
or garage door and operate
the lights. The reflected light should
show if they are working properly.
4Check all external lights and the horn. Refer
to the appropriate Sections of Chapter 13 for
details if any of the circuits are found to be
inoperative.4Visually check all wiring connectors,
harnesses and retaining clips for security, and
for signs of chafing or damage.

Note:From 1992, the cooling system on all models is filled with a long-life coolant mixture in production (“4-Year Longlife
Engine Coolant”/”Super Plus 40”). The manufacturers do not specify any renewal intervals for this later type of coolant as it is
intended to last the lifetime of the vehicle. Provided any topping-up is carried out with a similar coolant mixture of the correct
strength, coolant renewal is unnecessary. It is advisable to renew the coolant if the vehicle has covered a particularly high
mileage, or if the history of the car is uncertain, but this is up to the discretion of the individual owner.
