Coolant 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, and
three acoustic warning signals ⇒
are emitted.
This means that either the coolant level is too low or the coolant tempera-
ture is too high.
Coolant temperature too high
The instrument panel displays the following message 1)
: CHECK COOLANT IN-
STRUCTION MANUAL. ⇒ page 229.
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 the engine off and wait for it to cool down. Check the coolant level.
If the coolant level is correct, the overheating may be caused by a malfunc-
tion of the radiator fan. Check the radiator fan fuse and have it replaced if
necessary ⇒ page 258.
If the control lamp lights up again after driving on for a short distance, stop
the vehicle and switch the engine off . Contact a Technical Service or a spe-
cialised workshop.
Coolant level too low
The instrument panel displays the following message 1)
: STOP CHECK COOL-
ANT INSTRUCTION MANUAL.
First look at the coolant temperature gauge. If the needle is in the normal
range, top up with coolant at the earliest opportunity ⇒
.
WARNING
● If your vehicle is immobilised for technical reasons, move it to a safe
distance from traffic. Turn the engine off, turn the hazard lights on and
place the warning triangle.
● Never open the bonnet if you can see or hear steam or coolant escap-
ing from the engine compartment. Risk of scalding. Wait until you can no
longer see or hear escaping steam or coolant.
● The engine compartment is a dangerous area! Before carrying out any
work in the engine compartment, switch off the engine and allow it to
cool down. Always note the corresponding warnings ⇒ page 222.
Rear fog light

Engine management*
This warning lamp monitors the engine management sys-
tem for petrol engines.
The warning lamp (Electronic Power Control) lights up when the ignition
is switched on to show that the lamp is working properly. It should go out
once the engine is started.
If there is a fault in the electronic engine management system while you are
driving, this warning lamp will light up. Stop the vehicle and seek technical
assistance.
Glow plug system/engine fault
The warning lamp lights up to show that the glow plugs are
preheating the diesel engine. It flashes if there is an engine
fault.
Control lamp is lit
The control lamp lights up while the glow plug system is preheating.
When the warning lamp goes off, the engine should be started straight
away.
Control lamp flashes
If a fault develops in the engine management system while you are driving,
the glow plug system lamp will flash . Take the vehicle to a specialised
workshop as soon as possible and have the engine checked. Main beam headlights
This control lamp lights up when the main beams are on.
The warning lamp is switched on once main beams are on or once the
headlight flasher is operating.
For further information see ⇒ page 119.
Soot accumulation in the diesel engine particulate filter *
If the lamp lights up you should help the filter clean itself by driving in
the appropriate manner.
To do this, drive about 15 minutes in fourth or fifth gear (automatic gear-
box: S gear range) at a speed of 60 km/h (40 mph), with the engine running
at approximately 2000 rpm. In this way, the pollen build up in the filter is
burned. When cleaning is successful, the lamp turns off.
If the lamp does not turn off, or the three lamps turn on (particulate filter
, emission control system fault and glow plugs ), take the vehicle to
a specialised workshop to repair the fault.
WARNING
● Always drive according to the road weather conditions, the terrain
and traffic. Driving recommendations should never lead to illegal ma-
noeuvres in surrounding traffic.
● The diesel engine particulate filter may reach extremely high temper-
atures; it should not enter into contact with flammable materials under-
neath the vehicle. Otherwise there is a risk of fire.

Anti-lock brake system (ABS)*
A control lamp monitors the ABS.
The control 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 automat-
ic test sequence.
There is a fault in the ABS if:
● The control lamp does not light up when the ignition is switched on.
● The control lamp does not go out again after a few seconds
● The control lamp lights up when the vehicle is moving
The vehicle can still be braked in the normal way, without the ABS function.
Take the vehicle to a specialised workshop as soon as possible. For further
information on the ABS go to ⇒ page 187.
If a fault occurs in the ABS, the ESC* control 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 222, Working in the engine compartment.
● If the brake system 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 234, Brake fluid. If the brake fluid lev-
el has dropped below the “MIN” mark you must not drive on. Risk of acci-
dent. 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. Stop the vehicle and seek technical assis-
tance.
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

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 special-
ised workshop.
You should avoid using electrical equipment that is not absolutely necessa-
ry because this will drain the battery.
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. Tyre pressure
The tyre pressure control system controls the tyre speed and
the frequency spectrum of each tyre.
Fig. 50 Centre console:
tyre monitor system but-
ton
The tyre control lamp 1)
compares wheel revolutions and with it, the wheel
diameter of each wheel using the ESC. If the diameter of a wheel changes,
the tyre control lamp lights up. The wheel diameter changes when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a load.
● The wheels of one axle are under more pressure (for example, driving
with a trailer or on extreme slopes).
● The vehicle is fitted with snow chains.
● The temporary spare wheel is fitted.
● The wheel on one axle is changed.

Tyre pressure adjustment
Following the modification to tyre pressure or after changing one or more
wheels, the button ⇒ Fig. 50 must be kept pressed while the ignition is on
until an audible warning is heard and the warning lamp goes out.
If the wheels are under excessive load (for example, driving with a trailer or
heavy load), the tyre pressure must be increased to the recommended value
for a full load (see the sticker on the inside of the fuel flap). If the tyre moni-
tor system button is pressed down, the new tyre pressures are confirmed.
The tyre pressure control lamp lights up
If the tyre pressure of one or more wheels is much lower than the value set
by the driver, the tyre control warning lamp lights up ⇒
.
The tyre pressure control lamp flashes
If the tyre pressure control lamp flashes, this indicates a fault. Go to the
nearest specialised workshop.
WARNING
● When the tyre pressure control lamp lights up, reduce speed immedi-
ately and avoid any sudden manoeuvre or braking. Stop when possible,
and check the tyre pressure and status.
● The driver is responsible for maintaining correct tyre pressures. For
this reason, tyre pressure must be regularly checked.
● Under certain circumstances (for example, when driving in a sports-
like manner, in winter conditions or on a dirt track) the tyre control lamp
may light up or function incorrectly.
Note
If the battery is disconnected, the yellow warning lamp lights up after
turning the ignition on. This should turn off after a brief journey. Bulb defect
The warning lamp lights up when a bulb in the vehicle's ex-
terior lighting is defective.

WARNING
● Before opening the bonnet, read and observe the warnings on
⇒ page 222.
● If the brake warning lamp does not go out, or if it lights up when driv-
ing, the brake fluid level ⇒ page 234, Brake fluid in the reservoir is too
low. Risk of accident. Stop the vehicle and do not drive on. Obtain techni-
cal 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. Stop the vehicle and seek tech-
nical assistance.
Handbrake
This lamp lights up when the handbrake is applied. If you drive faster than 6 km/h (4 mph) with the handbrake on, the following
message will appear on the instrument panel display 1)
: HANDBRAKE ON. You
will also hear an acoustic warning signal ⇒ page 180.Engine oil pressure
If this warning lamp is red it indicates that the engine oil
pressure is too low.
If this warning symbol starts to flash, and is accompanied by three audible
warnings, switch off the engine and check the oil level. If necessary, add
more oil ⇒ page 225.
The instrument panel displays the following message 1)
: STOP ENGINE OIL
PRESSURE INSTRUCTION MANUAL .
If the symbol flashes although the oil level is correct, do not drive on. Do
not even run the engine at idle speed! Obtain technical assistance.
Checking the oil level
If the warning lamp is yellow the engine oil level should be checked as
soon as possible. Top up the oil ⇒ page 227 at the next opportunity.
Oil level sensor faulty*
If the yellow warning lamp flashes, take the vehicle to a specialised
workshop to have the oil level sensor checked. Until then it is advisable to
check the oil level every time you refuel.

Indicator for open doors or rear lid*
This warning lamp lights up if one of the doors or the rear
lid is open.
The warning light should go off when all the doors are closed correctly.
The system also works when the ignition is switched off. It should go off ap-
prox. 15 seconds after the vehicle is locked.
Electromechanical steering*
For vehicles with power steering, the level of steering assistance depends
on the vehicle's speed and on the steering angle.
The control lamp should light up for a few seconds when the ignition is
switched on. It should go out once the engine is started.
If the battery is disconnected, the indicator remains lit, even with the en-
gine running. The warning light only goes off after a distance of approx. 50
m.
There is a fault in the electromechanical steering system if the lamp does
not go out or lights up whilst the vehicle is in motion. The warning lamp
may appear in two different colours to indicate faults. If it lights yellow, this
indicates a minor fault. If it lights red, seek assistance from a specialised
workshop immediately, as the steering assistance is not working; in this
case you should not keep driving. Stop the vehicle and seek technical assis-
tance. The power steering does not work if the battery is flat or if the engine
is off (for example, for towing). You should take into account that you will
need considerably more power than normal to steer the vehicle if the power
steering is not working correctly or at all. For those vehicles fitted with ESC*, the “Steering manoeuvre recommenda-
tion” function is included. See
⇒ page 189.
Emission control system*
This warning lamp monitors the exhaust system.
Control lamp flashes:
