ance if necessary.The red symbols indicate a Priority 1 fault (serious malfunction).
Should a Priority 1 fault occur, a red warning symbol will appear at
the top of the display ⇒page 30, fig. 25. The symbol is accompa-
nied by a driver message giving you more information about the
fault. This symbol is accompanied by three warning chimes. The
symbol will keep flashing until the fault is corrected.
If several Priority 1 faults are detected at the same time, the symbols
are displayed one after the other for about 2 seconds at a time.
This message will disappear after about 5 seconds, but you can call
it up again at any time by pressing the button ⇒page 30.Alternator fault


as well as the alternator warning lamp while driving ⇒page 32, stop
the vehicle immediately and switch off the engine. In this case the
coolant pump is no longer being driven, and there is a risk of engine
damage.

Parking brake ! Please contact workshop
– If the symbol appears after you switch on the ignition
when the vehicle is stationary, please check whether you
can release the parking brake. If this is possible, you
should drive without delay to the nearest qualified work-
shop and have the fault rectified. If the parking brake
cannot be released you should obtain professional
assistance.
– If this symbol should appear while driving, there may be
a malfunction in the drive-away assist or the emergency
brake functions. You may not be able to apply the parking
brake. It is also possible that you cannot release the
parking brake after it has been applied. Drive the vehicle
to a qualified workshop and have the fault repaired.If the ABS fails, the ABS warning lamp
 will light up together with
the brake warning symbol
 ⇒.
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 fluid level in the reservoir is too low, this could
result in an accident. Do not drive on. You should obtain profes-
sional 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.
Note
The warning lamp
 in the instrument cluster will start flashing as
well if there is a fault in the brake system.
Fault in the cooling system

Faults in the cooling system must be rectified immedi-
ately.If the
 symbol flashes in the display, this means that
either the coolant temperature is too high or the coolant
level is too low. The symbol is accompanied by a driver
message giving you more information about the fault. This
message will disappear after about 5 seconds, but you can
call it up again at any time by pressing the button:
Switch off engine, check coolant level
–Stop the vehicle.
– Switch off the engine.
– Check the coolant level ⇒page 225.
– Add more coolant if necessary ⇒page 226.
– Wait for the symbol to go out before driving on.
– Obtain professional assistance if necessary.
If the coolant level is correct, the overheating may be caused by a
malfunction of the radiator fan.
If the alternator warning lamp lights up as well ⇒page 31, it is
possible that the drive belt has broken.

Technical data When starting from cold the engine may be a little noisy for the first
few seconds until oil pressure has built up in the hydraulic tappets.
This is quite normal and no cause for concern.
If the engine fails to start straight-away, switch off the starter after
about 10 seconds and try again after about half a minute.

doors could be locked with the remote control key and the occu-
pants could become trapped in the vehicle. The vehicle occupants
could be exposed to extremely high or low temperatures,
depending on the time of year.
