message Parking brake! You should have the fault corrected by a
qualified workshop without delay.

Brake system
The warning lamp flashes if the brake fluid level is too low
or if there is a fault in the ABS system or the parking
brake.

If the warning lamp flashes, there is a fault in the brake system.

The symbol in the instrument cluster display will flash at the
same time. You can press the
SET
explaining the fault ⇒ page 31.
If a failure should occur in the ABS, the ABS warning lamp
light up together with the brake warning lamp
WARNING
Before opening the bonnet and checking the brake fluid level,
observe the warning information on ⇒ page 221, "Working on
components in the engine compartment".
If the brake warning lamp does not go out, or if it lights up
when driving, the brake fluid level in the reservoir is too low – this
may cause an increased accident risk. Stop the vehicle and do not
drive on. You should obtain professional assistance.
If the brake warning lamp lights up together with the ABS
warning lamp, this can mean that the control function of the ABS
is out of action. As a result the rear wheels can lock relatively
easily when braking. This could cause the tail of the vehicle to skid
sideways. Drive carefully to the nearest qualified workshop and
have the fault rectified.
Fuel gauge
The gauge only works when the ignition is switched on.
Controls
When the needle reaches the reserve zone, the symbol
in the instrument cluster display ⇒ page 36 together with the
message Please refuel. At this point there are still about 8 litres of
fuel left in the tank. This is your reminder to fill up soon.
The tank capacity of your vehicle is given in the Technical data
section ⇒ page 279.
Never run the tank completely dry. If there is an irregular fuel supply,
misfiring can occur. This allows unburnt fuel to enter the exhaust
button to obtain a message system, which could cause overheating and damage the catalytic
converter.
