Where a turn signal bulb does not work, either on the trailer or on the tow-
ing vehicle, the turn signal bulb will not flash.
Anti-lock brake system (ABS)
The warning lamp monitors the ABS and the integrated elec-
tronic differential lock (EDL).
The warning lamp lights up for a few seconds when the ignition is switch-
ed on and while the engine is being started. The lamp 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
● The warning lamp lights up when the vehicle is moving
The vehicle can still brake in the normal way (except that the ABS control
function is out of action). Please take the vehicle to a specialised workshop
as soon as possible. For further information on the ABS, see ⇒ page 189.
If a malfunction should occur in the ABS, the ESC warning lamp will also
light up.
Entire brake system fault
If the ABS warning lamp lights up together with the brake warning lamp
⇒ page 71 (with the handbrake released), this indicates not only a
fault in the ABS function, but probably also a malfunction in the main brake
system ⇒
.
The symbol will light up on the instrument panel if there if a fault in the
brake system. Please refer to ⇒ page 78. Electronic differential lock (EDL) fault
The EDL works in conjunction with the ABS. The ABS indicator lamp will light
up to indicate an EDL fault. Please take the vehicle to a specialised work-
shop as soon as possible. For further information on the EDL, see
⇒ page 190.
WARNING
● Before opening the bonnet and checking the brake fluid level, ob-
serve the warning information in ⇒ page 227, Work in the engine com-
partment.
● 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. If the fluid level has dropped below the "MIN" mark
you must not drive on, as there is a risk of accident. Obtain technical as-
sistance.
● If the brake fluid level is correct, the fault in the brake system may
have been caused by a fault in the ABS control function. As a result, the
rear wheels can lock relatively easily when braking. Under certain cir-
cumstances, the rear of the vehicle could suddenly sway from side to
side, with the subsequent danger of skidding. Drive carefully to the near-
est specialised workshop and have the fault repaired.
Seat belt warning lamp*
The warning lamp acts as a reminder to the driver to fasten
the seat belt. After switching on the ignition, the warning lamp will remain lit until the
driver and front passenger (if applicable) have fastened their seat belts.
When the vehicle has reached a certain speed, you will also hear a warning
signal and the warning light will flash.
For further information on the seat belts, see ⇒ page 23.
71
Cockpit
When the engine is warm, or at outside temperatures above +8 °C, the
warning lamp will only light up very briefly.
Note
● If the glow plug indicator lamp should start flashing while the vehicle is
moving, this indicates a fault in the engine management system. The en-
gine should be serviced without delay.
● If the indicator lamp fails to light up when the ignition is switched on,
this can mean that the glow plug system is defective. The engine should be
serviced.
Brake system
The warning lamp flashes when the handbrake is applied, or
if the brake fluid level is too low or if there is a fault in the
ABS system. If the warning lamp flashes (and the handbrake is not applied), stop the
vehicle and check the brake fluid level ⇒
⇒ page 236.
If a failure should occur in the ABS, the ABS warning lamp will light up
together with the brake warning lamp ⇒
.
Handbrake on
The warning lamp also lights up when the handbrake is applied. In addi-
tion to this, the handbrake warning ⇒ page 77 switches on after driving
for 3 seconds at a speed above 5 km/h.
WARNING
● Before opening the bonnet and checking the brake fluid level, ob-
serve the warning information in ⇒ page 227, Work in the engine com-
partment.
● If the brake warning lamp does not go out, or if it lights up when driv-
ing, the brake fluid level in the reservoir is too low and this may cause an
increased accident risk. Stop the vehicle and 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.

WARNING
● Before opening the bonnet and checking the brake fluid level, ob-
serve the warning information in ⇒ page 227, 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.
