238Topping up and changing the brake fluid
It is best to have the brake fluid changed by a professional.Brake fluid absorbs damp. Therefore, in the course of time it will absorb water
from the ambient air. If the water content in the brake fluid is too high, the
brake system could corrode. In addition, the boiling point of the brake fluid
will be considerably reduced. This could adversely affect the braking ability in
certain circumstances.
For this reason the brake fluid must be changed periodically.
Your vehicle's Service Schedule will tell you when the brake fluid has to be
renewed.
We recommend you have the brake fluid changed as part of a regular Inspec-
tion Service at your garage. They are familiar with the procedure and have the
necessary special tools and spare parts as well as the proper facilities for
disposing of the old fluid.
Use only the genuine brake fluid specified by the factory Specialist garages
know that the brake fluid -DOT 4- is factory approved. The brake fluid must be
new.
WARNING
•Therefore, it must always be kept cl osed in its original container. Keep
out of the reach of children. Failure to comply could result in poisoning.•Heavy use of the brakes may cause a vapour lock if the brake fluid is left
in the system for too long. This would seriously affect the efficiency of the
brakes and the safety of the car, leading to the risk of accident.Caution
Please note that brake fluid will attack the paintwork on contact.
For the sake of the environment
If the fluid has to be drained out of the brake system, use an appropriate
container to catch the used brake fluid and dispose of it in the proper
manner.BatteryGeneral notes
All work on batteries requires specialist knowledge.The battery is virtually maintenance-free and is checked in the Inspection
Services.
We recommend that you replace a battery once it is older than 5 years.
Disconnecting the battery
If the battery is disconnected, some of the vehicle's functions will become
inoperative (e.g. electric windows). These functions will require resetting
after the battery is reconnected. For this reason, the battery should only be
disconnected from the vehicle's electrical system when absolutely necessary.
Long periods of non-use
The battery will gradually lose its charge because certain electrical equip-
ment continues to draw current even when the ignition is off. If you park the
vehicle for long periods of time in winter you should take the battery out of
the vehicle and keep it in a frost-proof room. Store the battery in a place
where it cannot “freeze up” and become damaged. At warm outside temper-
atures it is sufficient to disconnect the negative terminal of the battery. Even
when the battery is not connected you should charge it from time to time.

Wheels and tyres
244Significant tyre pressure lossThe tyre symbol
is displayed and indicates that the tyre pressure for a least
one tyre is insufficient.
- Stop the vehicle.
- Switch the engine off.
- Check the tyre(s).
- Change the wheel if necessary.
Tyre pressure monitoring (RKA+)*
The type pressure monitor display on the instrument panel
indicates that the pressure is too low.The tyre pressure monitoring system makes use of the ABS sensors to
compare the rolling circumference and the frequency characteristics of the wheels. If the rolling circumference or frequency characteristic changes on
one or more wheels, the tyre pressure warning lamp
will light up. The fault
will also be indicated by a warning buzzer. The position of the affected tyre
will also be shown (if only one tyre is affected) on the centre display of the
instrument panel.
The rolling circumference and frequency characteristics can change if:
•the tyre pressure is too low.•the tyre has suffered structural damage.•the wheels or the inflation pressures have been changed without initial-
ising the system (see Adjusting the tyre pressure settings).•there is a greater load on the wheels of one axle (e.g. if you are carrying
more passengers or luggage).•the road surface under the left wheels is different to the road surface
under the right wheels for a long period.•when driving with snow chains.
Adjusting the tyre pressure settings (initialising the tyre pressure
monitoring system)
After any incident regarding the wheels of your vehicle, e.g. after modify the
tyre pressure ⇒page 245 or after changing of swapping around wheels ⇒
page 180 - with the vehicle at a standstill and the engine running - press
⇒ fig. 188. The yellow warning lamp
will light up. Hold the button down
for 2 seconds until the warning lamp goes out and an acoustic warning is
given. You can now release the button.
If the wheels are subjected to extremely stress (e.g. heavy load), the tyre pres-
sure must be increased to the recommended value for the maximum load
(see the adhesive label on the inside of the fuel tank flap) and then initialise
the system.
Tyre pressure warning lamp on
When you switch on the ignition, the tyre pressure warning lamp
will light
up for about 2 seconds. There is a fault in the system if the indicator stays on
permanently after switching on the ignition. The instrument panel also

right.
– Remove the bulb and fit the new one in the headlight casing with the tab upwards, starting to position it from below.
– Clip on the spring, raising it and pressing it slightly while turning
it anti-clockwise. To ensure correct lighting, the filament must be
vertical. When changing the bulb, you can check the position of
the bulb through the headlight glass.
– Connect the connector to the bulb.
– Fit the cover, first inserting the side tabs and then closing the cover and the brace. Make sure that the gasket sits well on the
casing cover during the operation.
– Check whether the new bulb is working.
– Have the headlight settings checked as soon as possible.
