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 242.
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 272.
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 235.

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. 

83
Cockpit
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 (37 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 196. 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 235, 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 249, 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.
