WARNING
● Before opening the bonnet and checking the brake fluid level, ob-
serve the warning information in ⇒ page 235, Work in the engine com-
partment.
● If the brake fluid level in the reservoir is too low, this could result in
an accident. Do not drive on! Obtain technical assistance.
● If the brake warning lamp lights up together with the ABS warning
lamp, this can mean that there is a fault in the ABS control function. As a
result, the rear wheels can lock relatively easily when braking. Under cer-
tain circumstances, the rear of the vehicle could suddenly sway from side
to side, with the subsequent danger of skidding. Drive carefully to the
nearest specialised workshop and have the fault repaired.
Fault in the cooling system
Faults in the cooling system must be repaired immediately.
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
following message will appear in the display together with the
symbol:
Switch off engine and check coolant level
– Stop the vehicle.
– Switch the ignition off.
– Check the coolant level ⇒ page 241.
– Add more coolant if necessary ⇒ page 242.
– 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 malfunc-
tion of the radiator fan.
If the alternator warning lamp lights up as well ⇒ page 72, it is possible that
the drive belt has broken.
CAUTION
Do not drive on if the symbol has come on to indicate a fault in the cool-
ing system, otherwise there is a risk of engine damage.
Engine oil pressure too low
If the engine oil pressure is too low the fault must be re-
paired immediately.
If the symbol flashes in the display, the oil pressure is too low.
The following message will appear in the display together with the
symbol:
Switch off engine, check oil level
– Stop the vehicle.
– Switch the ignition off.
– Check the engine oil level ⇒ page 239.
– Obtain professional assistance if necessary.
Engine oil level too low
If the engine oil level is too low, add more oil ⇒ page 240.

Photosensor/rain sensor faulty
Automatic headlights / automatic wipers faulty
If the symbol lights up, this means that the photosensor/rain sensor is
not working. For safety reasons, the dipped beam headlights will then be
switched on permanently when the light switch is set to the AUTO position.
However, you can still switch the lights on and off in the normal way with
the light switch. If the rain sensor is faulty, the functions operated via the
windscreen wiper lever will still be available. You should have the photosen-
sor/rain sensor checked by a specialised workshop as soon as possible.
Worn brake pads
If the symbol lights up, have the front brake pads (and, for safety rea-
sons, the rear pads as well) inspected by a specialised workshop.
Speed warning 1
If the symbol lights up, this means you are exceeding the speed that has
been pre-set with the speed warning function. You should reduce your
speed accordingly ⇒ page 85.
Headlight range control faulty
This symbol indicates a malfunction in the dynamic headlight range con-
trol. Take the vehicle to a specialised workshop to have the dynamic head-
light range control function repaired. Adaptive headlights* faulty
Adaptive headlights faulty
This symbol indicates that the adaptive headlight system is faulty. Take
the vehicle to a specialised workshop to have the headlights or the adap-
tive headlight control unit repaired.
Washer fluid level low
If the symbol lights up, top up the fluid for the windscreen washer and
headlight washer system* ⇒ page 243.
Speed warning 2
If the symbol lights up, this means you are exceeding the speed that has
been pre-set. You should reduce your speed accordingly ⇒ page 85.
Battery voltage too high or too low
If the symbol lights up, take the vehicle to a specialised workshop and
have the following items checked:
● Poly V-belt
● Battery condition
It is also advisable to check whether the alternator warning lamp has come
on ⇒ page 72.
178Driving
● The Start-Stop System is manually deactivated.
● The windscreen de-mist function is turned on.
● The temperature of the passenger compartment exceeds the comfort
limits (button ECON
should not be selected).
● If more than 50% of the airflow that the fan can supply is ordered.
● Temperature setting HI or LO is selected.
● The engine coolant temperature is insufficient.
● The alternator is faulty, for example the V-belt has ruptured.
● If any of the conditions described in the previous section are not fulfil-
led.
WARNING
Never allow the vehicle to move with the engine off for any reason. You
could lose control of your vehicle. This could cause an accident and seri-
ous injury.
● Power steering does not work when the engine is not running. That is
why it is much more difficult to turn the steering wheel.
● Turn off the Start-Stop system when driving through water (fording
streams, etc.).
Note
● For vehicles with the Start-Stop function and a manual gearbox, when
the engine is started, the clutch must be pressed.
● When the conditions for the Start-Stop function are not fulfilled, the in-
strument panel displays the Start-Stop indicator dimmed.
● If the steering wheel is turned more than 270°, Stop will not function;
however, the angle of steering wheel turn does not affect starting the vehi-
cle. Activating and deactivating the Start-Stop function
Fig. 148 The Start-Stop
function button.
Every time the ignition is switched on, the Start-Stop function is au-
tomatically switched on.
Manually deactivating the Start-Stop function
– Press the ⇒ Fig. 148 button located on the centre console.
When the Start-Stop function is deactivated, the pushbutton in-
dicator lights.
– If the Start-Stop function is operating then the engine starts im-
mediately.
Switching the Start-Stop function on manually
– Press the ⇒ Fig. 148 button located on the centre console.
The indicator on the button will go out.
236Checking and refilling levels
WARNING (Continued)
● Protect face, hands and arms from any hot steam or hot coolant fluid
released by covering the cap with a large, thick rag when opening the ex-
pansion tank.
● If any tests have to be performed with the engine running, there is an
added safety risk from the rotating parts (e.g. drive belts, alternator, ra-
diator fan, etc.) and from the high-voltage ignition system.
● Observe the following additional warnings if work on the fuel system
or the electrical system is necessary:
–Always disconnect the battery from the on-board network.
– Do not smoke.
– Never work near open flames.
– Always keep an approved fire extinguisher immediately available.
CAUTION
When topping up fluids, make sure the correct fluid is put into the correct
filler opening. This can otherwise cause serious malfunctions or engine
damage.
For the sake of the environment
Inspect the ground underneath your vehicle regularly so that any leaks are
detected at an early stage. If you find spots of oil or other fluids, have your
vehicle inspected at the workshop.
● When the external temperature and level of humidity are high or when
the engine stops, it is possible for water to drop from the air conditioning
system evaporator potentially forming a small puddle on the ground. This is
normal and does not indicate a leak.
Note
On right-hand drive vehicles some of the reservoirs mentioned below are lo-
cated on the other side of the engine compartment. Releasing the bonnet
The bonnet is released from inside the vehicle.
