Coolant level* / temperature  (red)
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 224.
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 250.
If the warning lamp lights up again after driving on for a short distance,
stop the vehicle and switch the engine off. Contact an Authorised Service
Centre or a specialised workshop.

First look at the coolant temperature gauge. If the needle is in the normal
range, top up with coolant at the earliest opportunity

●
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 217.

Coolant temperature  (blue)
This lamp lights up when the coolant is below approximately 45°C. When it
exceeds this temperature the lamp turns off.

Turn signals  
The indicator lamp flashes when the turn signals are in op-
eration.
Depending on which turn signal is operating, either the left  or right 
turn signal lamp flashes. Both indicator lamps will flash at the same time
when the hazard warning lights are switched on.
If any of both turn signals fails, the indicator lamp will start flashing twice
faster than normal.
For further information on the turn signals, please see 
⇒ page 122.

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. It flashes if there is an engine fault.
Warning lamp  is lit
The warning lamp  lights up while the glow plugs are preheating. When
the warning lamp goes off, the engine should be started straight away.
Warning lamp  flashes
If a fault develops in the engine management system while you are driving,
the glow plug lamp will flash . Take the vehicle to an Authorised Service
Centre as soon as possible and have the engine checked.

Main beam headlights 
This warning 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 122.

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, with the engine running at ap-
proximately 2000 rpm. In this way, the pollen build up in the filter is burned.
When cleaning is successful, the indicator turns off.
If the warning lamp  does not turn off, or the three lamps turn on (partic-
ulate 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 warning lamp monitors the ABS.
The indicator 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 warning lamp  does not light up when the ignition is switched on.
● The warning lamp does not go out again after a few seconds
● The warning 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 182.
If a fault occurs in the ABS, the ESC (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 217, 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 229, Brake fluid. If the fluid level has drop-
ped below the “MIN” mark you must not drive on. Risk of accident. Ob-
tain 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
