The yellow warning lamp remains on if the system is faulty or if
the pressure is too low in at least one tyre. In the event of a system
fault, the letters TPMS are displayed in the centre of the instrument
panel ⇒ fig. 45. If the tyre pressure drops rapidly, message A
⇒ fig. 46 will be shown on the central display of the instrument
panel. If the pressure loss is more gradual, message B ⇒ fig. 46
will be shown on the central display of the instrument panel. This
message does not show the tyre affected. Should any of these
warnings be displayed:
– Stop the vehicle.
– Check the tyres. Although the warning corresponds to just one
tyre, you should also check the others.
– Correct the tyre pressure ⇒ page 236.
For more detailed information on the tyre pressure monitoring system,
please refer to ⇒ page 235.
Cruise speed (Cruise control)*
The indicator lamp on the instrument panel lights up when the cruise
control system is operating.
Trailer turn signals*
This turn signal lamp flashes when the turn signals are op-
erating while towing a caravan or trailer. The turn signal lamp flashes when the turn signals are operated if a trail-
er is correctly coupled to the vehicle. 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 qualified workshop as
soon as possible. For further information on the ABS, see ⇒ page 185.
If a malfunction should occur in the ABS, the ESP warning lamp will also
light up.
Entire brake system fault
If the ABS warning lamp lights up together with the brake warning lamp
⇒ page 70 (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 77.

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 qualified work-
shop as soon as possible. For further information on the EDL, see
⇒ page 186.
WARNING
● Before opening the bonnet and checking the brake fluid level, ob-
serve the warning information in ⇒ page 221, 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.Turn signals and hazard warning lights
Depending on which turn signal is operated, either the left or right turn
signal lamp flashes. Both turn signal lamps will flash when the hazard warn-
ing lights are switched on.
If a turn signal fails, the indicator lamp will start flashing twice as fast as
normal.
This does not apply when towing a trailer. Where a turn signal bulb does not
work, either on the trailer or on the towing vehicle, the turn signal bulb will
not flash. For further information on the turn signals, see ⇒ page 122.
Electronic Stability Programme
This warning lamp monitors the Electronic Stability Pro-
gramme (ESP).
The warning lamp has the following functions:
● It will start flashing to indicate that ESP is counteracting an unstable
driving condition.
● It lights up when the ignition is switched on for approx. 2 seconds while
the function is checked.
● The warning lamp will light up if there is a malfunction in the ESP.
● It will light up after the battery has been disconnected.
● The warning lamp will light up 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
166Driving
The Electronic Stability Programme (ESP) contains the electronic differential
lock (EDL) and the traction control system (TCS). The ESP function works to-
gether with the ABS. If a fault in the ABS occurs, both warning lamps light
up, but if the ESP fails, only the ESP warning lamp lights up.
The ESP is started automatically when the engine is started.
The ESP switch deactivates both TCS and ESP functions. The ESP, in spite of
being deactivated, will always self-connect when necessary if brakes are be-
ing used.
The TCS can be deactivated when in cases where wheel sliding is desirable.
For example:
● When driving with snow chains.
● When driving in deep snow or on loose surfaces.
● When the vehicle is stuck, to rock it backwards and forwards.
Next, the button should be pressed to reactivate the TCS.
When does the lamp light up or flash
●
On switching the ignition on, it lights up for about two seconds to carry
out a function control.
● The warning lamp will start flashing when the vehicle is moving if the
ESP or the TCS is activated.
● It will light up continuously if there is a malfunction in the ESP.
WARNING
● The Electronic Stability Programme (ESP) cannot defy the laws of
physics. This should be kept in mind, particularly on slippery and wet
roads and when towing a trailer.
● Always adapt your driving style to suit the condition of the roads and
the traffic situation. Do not let the extra safety afforded by ESP tempt you
into taking any risks when driving, as this can cause accidents.
● Please refer to the corresponding warning notes on ESP in
⇒ page 184, Intelligent technology.

Electronic Stability Programme (ESP) General notes
The Electronic Stability Programme increases the vehicle's
stability on the road.
Fig. 149 Centre console
with ESP switch
The ESP is designed to increase the degree of control in situations where
the vehicle approaches the limits of adhesion, especially when accelerating
and cornering. It reduces the risk of skidding and improves stability in all
road conditions. The system is active across the entire speed range. The anti-lock brake system (ABS), the electronic differential lock (EDL) and
the traction control system (TCS) are all integrated into the Electronic Stabil-
ity Programme.
How it works
The ESP control unit processes data from the three integrated systems. It al-
so processes additional inputs provided by other high-precision sensors.
These register the vehicle's rotation about the vertical axis (yaw rate), later-
al acceleration, brake pressure and steering wheel angle.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehicle. If the desired course is not being
maintained (for instance, if the vehicle is starting to skid), then the ESP
compensates automatically by braking the appropriate wheel.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. If the vehicle
over swerves (tendency of the rear to leave the
road), the brakes will act on the front wheel facing the outside of the bend.
If the vehicle under swerves (tendency to leave the bend), the braking force
is applied to the rear wheel facing the inside of the bend.
The ESP works in conjunction with the ABS ⇒ page 185. If a malfunction
should occur in the ABS, the ESP will also stop working.
Deactivating
The ESP is activated automatically when the engine is started and performs
a self-test routine.
186Intelligent technology
Brake assist system
The brake assist system helps the driver to achieve optimum
braking effect.
The brake assist system helps to increase braking power and thus to ach-
ieve a shorter stopping distance. If the driver presses the brake pedal very
quickly, the brake assist system automatically boosts the braking force to
the maximum level, up to the point where the anti-lock brake function (ABS)
intervenes to stop the wheels from locking. You should then keep the brake
pedal pressed until the vehicle has braked to the required speed. The brake
assist system switches itself off as soon as you release the brake pedal.
The brake assist system will not be operative if there is a malfunction in the
ABS or the ESP.
WARNING
Please remember that the accident risk always increases if you drive too
fast, especially in corners or on a slippery road, or if you follow too close
behind the vehicle in front of you. An increased accident risk cannot be
compensated even by the brake assist system. Risk of accident.
Electronic differential lock (EDL)
The electronic differential lock prevents the loss of traction
caused if one wheel starts spinning. General notes
The electronic differential lock (EDL) helps the vehicle to start moving, ac-
celerate and climb a gradient in slippery conditions where this may other-
wise be difficult or even impossible. How it works
The EDL works automatically, without the driver's involvement. With the aid
of the ABS sensors, the system monitors the rotational speed of the drive
wheels
⇒ page 185. If a considerable difference in revs is detected (approx.
100 rpm) in the speed of the drive wheels, e.g. when only one part of the
surface supporting the wheels is slippery, the system applies the brake to
slow down the skidding wheel so that more of the power is directed to the
other wheels. The systems works up to a speed of approx. 80 km/h. The
system will make noise while it is working.
Starting the vehicle
If one wheel has less grip and starts spinning (for instance, if one of the
drive wheels is on ice), keep pressing the accelerator gradually until the ve-
hicle starts moving.
Overheating of the brakes
To prevent the brake disk of the braked wheel from overheating, the EDL
cuts out automatically if subjected to excessive loads. In this case, the vehi-
cle will continue to run and will have the same running properties as those
of another without EDL.
The EDL will switch on again automatically when the brake has cooled
down.
WARNING
● When accelerating on a uniformly slippery surface (for instance all
four wheels on ice or snow), press the accelerator gradually and careful-
ly. Despite EDL, the drive wheels may otherwise start to spin. This could
impair the vehicle's stability. Risk of accident.
● Even with EDL, you should always adjust your speed to suit the road
and traffic conditions. Do not let the extra safety features tempt you into
taking any risks when driving. Failure to do so could result in an accident.
