WARNING
•
Failure to observe warning lamps and warning messages can result in
serious personal injury or damage to your vehicle.
•
The risk of an accident increases if your vehicle breaks down. Use a
warning triangle to draw the attention of other road users to your
stationary vehicle so that it does not represent a danger.
•
The engine compartment of any motor vehicle is a dangerous area!
Before you open the bonnet to work on the engine or in the engine compart-
ment, you must switch off the engine and allow it to cool to reduce the risk
of scalding or other injuries. Read and observe the relevant warnings
⇒ page 209.Note
•
The appropriate warning lamp for a fault will light up in vehicles without
warning or information texts in the display.
•
In vehicles with warning or information texts in the display, the appro-
priate warning lamp for a fault will light up and a warning or information text
will also appear in the display.
Trailer turn signals
This warning lamp also flashes when the turn signals are
operated while towing a caravan or trailer.The warning lamp
flashes when the turn signals are operated, provided a
trailer is correctly attached and connected to the vehicle.

74Fault in the exhaust system*
Exhaust gas indicator
If the indicator
flashes it signals possible damage to the catalytic
converter caused by defective combustion. Reduce speed immediately and
go to the nearest specialised workshop to check the engine. At the same
time, a text message or the necessary operations may appear on the instru-
ment panel.
If the indicator lights up , a fault has developed during driving which has
affects the quality of the exhaust gas (e.g. lambda probe fault). Reduce speed
immediately and go to the nearest specialised workshop to check the engine.
At the same time, a text message or the necessary operations may appear on
the instrument panel.
Traction control system (TCS)*
The traction control system prevents the driven wheels from
spinning when the vehicle is acceleratingThe warning lamp lights up when the ignition is switched on and should turn
out after about 2 seconds.
When the TCS is operating while driving, the warning lamp flashes. If the
system is deactivated or if there is any fault in the same, the warning lamp will
remain lit.
It will also come on if a fault should occur in the ABS because the TCS oper-
ates in conjunction with the ABS. For further information see ⇒ page 181.
Electronic stabilisation programme (ESP)*
This warning lamp monitors the electronic stabilisation
programme.
This programme includes the ABS, EDL and TCS.
The warning lamp
has the following functions:
•
It will light for about 2 seconds when the ignition is switched on while a
test of the function is carried out.
•
It flashes when the ESP is activated when driving.
•
It will light up continuously if there is a malfunction in the ESP.
•
It will light up continuously if the ESP is switched off.
•
It will also come on if a fault should occur in the ABS because the ESP
operates in conjunction with the ABS.
If the ESP warning lamp
lights up and stays on after the engine is started,
this may mean that the control system has temporarily switched off the ESP.
In this case the ESP can be reactivated by switching the ignition off and then
on again. If the warning lamp goes out, this means the system is fully
functional.
Anti-lock brake system (ABS)
A warning lamp system monitors the ABS.
The warning lamp
should light up for a few seconds when the ignition is
switched on. It goes out again after the system has run through an automatic
test sequence.
There is a fault in the ABS if:
•
The warning lamp
does not light up when the ignition is switched on.
•
The warning lamp does not go out again after a few seconds.

Tips and Maintenance
Te c h n i c a l D a t a
•
The warning lamp lights up when the vehicle is moving.
The vehicle can still be braked in the normal way (except that the ABS control
function will not function). Please take the vehicle to a qualified workshop as
soon as possible. For further information on the ABS see the ⇒page 180.
If a fault occurs in the ABS, the ESP* warning lamp will also light up.
Brake system fault
If the ABS warning lamp
lights up together with the brake warning lamp
, this indicates not only a fault in the ABS function, but also a possible fault
in the brake system ⇒ .
WARNING
•
Before opening the bonnet, read and observe the warnings on
⇒ page 209, “Working in the engine compartment”.
•
If the brake warning lamp
should light up together with the ABS
warning lamp
, stop the vehicle immediately and check the brake fluid
level in the reservoir ⇒page 221, “Brake fluid”. If the fluid level has
dropped below the “MIN” mark you must not drive on. Risk of accident.
Obtain technical assistance.
•
If the brake fluid level is correct, the fault in the brake system may have
been caused by a failure of the ABS system. This could cause the rear
wheels to lock quickly when you brake. This could cause the rear to break
away. Risk of skidding. Drive carefully to the nearest qualified workshop
and have the fault corrected.
Differential lock fault (EDL)*
EDL operates along with the ABS in vehicles equipped with an
Electronic Stabilisation Program (ESP)*A malfunction in the EDL is indicated by the ABS warning lamp
. Please
take the vehicle to a qualified workshop as soon as possible. For further infor-
mation on the EDL ⇒page 182.
Diesel particulate filter indicator lamp*
When the indicator
lights on the instrument panel it signals that the filter
is blocked by soot because of frequent short journeys. To clean the filter of
these particulates, drive at a constant speed of 60 km/h for 15 minutes.
Always respect the speed limit. The most efficient way to clean the diesel
particulate filter is to drive in 4th or 5th gear, at approximately 2,000 rpm
⇒ . This causes a temperature increase sufficient to burn the soot in the
filter.
If the lamp
remains lit afterwards, go to a specialised workshop to
examine the problem.
While the lamp is lit (filter blockage signal) fuel consumption increases
and the engine may lose power in some cases.
At the same time, a text message or the necessary operations may appear on
the instrument panel.
WARNING
•
Try to always adapt the speed of the vehicle to weather, road and traffic
conditions. The indications suggested by the warning lights should not
lead you to disobey the highway code.

brake fluid level falls too low or if there is a fault in the brake
system.
This warning lamp
lights up if
•
If the handbrake is on
•
If the brake fluid level is too low
•
If there is a fault in the brake system
This warning lamp can light up together with the anti-lock brake system
warning lamp.
WARNING
•
Before opening the bonnet, read and observe the warnings on
•
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. Risk of accident.
Stop the vehicle and do not drive on. Obtain technical assistance.
•
If the brake warning lamp
lights up together with the ABS warning
lamp
, the control function of the ABS could be out of action. This could
cause the rear wheels to lock quickly when you brake. This could cause the
rear to break away. Risk of skidding. Drive carefully to the nearest qualified
workshop and have the fault corrected.
Alternator
This warning lamp signals a fault in the alternator.
The warning lamp
lights up when the ignition is switched on. It should go
out when the engine has started running. If the warning lamp
lights up while driving, the alternator is no longer
charging the battery. You should immediately drive to the nearest qualified
workshop.
You should avoid using electrical equipment that is not absolutely necessary
because this will drain the battery.
If the indicator flashes the voltage is insufficient for normal vehicle
operation.
Fuel level / reserve
This symbol lights up to indicate that the fuel tank is down to
the reserve level.This lights when only 7 litres of fuel remain in the tank. Also, an audible
warning is given. This serves as a reminder to fill up with fuel at the earliest
opportunityBulb defect
The warning lamp lights up when a bulb in the vehicle's exte-
rior lighting is defective.The warning lamp

Tailgate open display*
When the ignition is switched on, the warning light indicates that the tailgate
is open.
The warning light only goes off when the tailgate is completely closed.Washer fluid
This warning lamp lights up to indicate that the windscreen
washer level is too low.This serves as a reminder to fill up the reservoir at the earliest opportunity
⇒ page 218.Door open display*
This light comes on when a door is open or incorrectly closed.Brake pad wear indicator*
As the brake pad wear indicator only monitors the front brake pads, it is advis-
able to have the rear brake pads inspected at the same time.
WARNING
Have the brake pads inspected immediately by a qualified dealership if the
warning display
lights up.
Engine oil pressure
The warning light indicates that the engine oil pressure is too
low or that the oil gauge does not operate correctly.It lights up or flashes in red (oil pressure too low)
If the warning light lights up or starts to flash in red while driving, a sound
signal will also be emitted three times when the engine speed exceeds 1500
rpm. Stop and switch off the engine: check the oil level and replace if neces-
sary ⇒page 214.
If the warning light flashes even though the oil level is correct, do not
continue driving The engine should not be turning even at idle speed. Obtain
technical assistance.
If, while driving, the engine speed falls to below idling speed, the oil pressure
warning light may come on. Increase the engine speed by accelerating or
dropping to a lower gear.
A yellow light comes on (oil level* too low)
If the warning light comes on in yellow, this indicates that the oil level is too
low. Switch off engine, check oil level, replacing where necessary.
When the bonnet is opened the oil level warning will fall to zero. But if it is not
topped with oil, the light will come back on after approximately 100 km.
Yellow flashing (defective oil level*)
If the oil gauge is faulty, a sound signal is emitted and the warning light
flashes several times.
At the same time, a warning appears briefly on the on board computer
display*. The engine should immediately be checked by a Technical Service
Centre.
From the moment the defect appears until the engine is checked, the level of
oil should be constantly monitored, preferably every time the vehicle is
refuelled.

78Coolant Level* / temperature
The warning lamp lights up if the coolant temperature is too
high or if the coolant level is too low.There is a fault if:•
The warning symbol does not go out again after a few seconds.
•
The warning lamp lights up or flashes while the vehicle is moving, while
three acoustic warning signals ⇒ are emitted.
This means that either the coolant level is too low or the coolant temperature
is too high.
Coolant temperature too high
First look at the coolant temperature gauge. The coolant temperature is too
high if the needle is over the warning area on the dial. Stop the vehicle,
switch off the engine and wait for it to cool down. Check the coolant level.
If the coolant level is correct, the overheating may be caused by a malfunction
of the radiator fan. Check the radiator fan fuse and have it replaced if neces-
sary ⇒page 241.
If the warning lamp lights up again after driving on for a short distance, stop
the vehicle and switch off the engine . Contact an Authorised Service Centre
or a qualified workshop.
Coolant level too low
The following information text is displayed in the instrument panel display.
First look at the coolant temperature gauge. If the needle is in the normal
range, top up with coolant at the earliest opportunity ⇒.
