192If required, the ESP can also be enabled and disabled manually by briefly
pressing the button ⇒ page 191, fig. 160. The ESP warning lamp lights
up when the system is switched off, see ⇒page 68.
In general, the ESP should be left switched on at all times. In particular
circumstances where a certain amount of wheel slip is desirable, it may be
advisable to switch off the ESP. Examples:•when driving with snow chains•when driving in deep snow or on loose surfaces•when rocking the vehicle backwards and forwards to free it.
The ESP should be switched on again afterwards as soon as possible.WARNING
The ESP is not able to overcome the physical limits of adhesion. Even with
ESP, you should always adjust your speed to suit the conditions. Please

extra safety features tempt you into taking any risks when driving. Failure
to do so could result in an accident.Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under braking.The anti-lock brake system (ABS) is an important part of the vehicle's active
safety system. However, the ABS will not necessarily guarantee shorter stop-
ping distances in all conditions. For instance, on loose gravel or fresh snow
on top of an icy surface (conditions which anyway require extreme care and
reduced speed), the stopping distance with ABS may even be slightly longer. How the ABS works
The system runs an automatic self-check when the vehicle reaches a road
speed of about 6 km/h. This may be accompanied by a noise from the ABS
pump.
When one of the wheels is turning very slowly in relation to the road speed
and is close to locking up, the system will reduce the brake pressure on that
wheel. The driver is made aware of this adjustment process by a vibration of
the brake pedal
and an audible noise. This is a deliberate warning to the
driver that one or more of the wheels is tending to lock up and the ABS control
function has intervened. In this situation it is important to keep the brake
pedal fully depressed so the ABS can regulate the brake application, but do
not “pump” the brake pedal.
WARNING
The grip provided by ABS is still subjec t to the physical limits of adhesion.
Always bear this in mind, especially on wet or slippery roads. If you notice
that the ABS is working (to counteract locked wheels under braking), you
should reduce speed immediately 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.
Note
If a malfunction should occur in the ABS, this is indicated by a warning lamp

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 achieve
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) inter-
venes 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.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, accel-
erate and climb a gradient in slippery conditions where this may otherwise 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 192. 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 vehicle
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 vehicle 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 carefully.
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.

Trailer towing
204Where possible, operate the trailer with the maximum permitted drawbar
load on the ball joint of the towing bracket, but do not exceed the specified
limit.
Tyre pressure
Check the tyre pressures on your vehicle, and adjust for “full load” conditions
(refer to the sticker listing the tyre pressures on the door pillar). It may also be
necessary to adjust the tyre pressures on the trailer according to the recom-
mendations of the trailer manufacturer.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case you should have additional mirrors
fitted. The two exterior mirrors should be fitted on folding arms. Adjust the
mirrors to give sufficient rear vision.
Headlights
Before starting a journey, check the headlight beam settings with the trailer
hitched up. If necessary, alter the height of the headlight beams by means of
the headlight range control. See ⇒page 120.
Power supply
When you remove the ignition key, the power supply to the trailer is inter-
rupted.
Removable ball joint coupling
Vehicles with a factory-fitted towing bracket are equipped with a removable
ball joint coupling. This is stored in the spare wheel well in the luggage
compartment together with the necessary fitting instructions.
Note
If you frequently tow, we recommend you also have the vehicle serviced
between services.
Notes on towing
Towing a trailer involves additional attention by the driver.Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slow to allow for
the unbalanced weight distribution.
Speed
The stability of the vehicle and trailer is reduced with increasing speed. There-
fore, it is advisable not to drive at the maximum permissible speed in unfa-
vourable road, weather or wind conditions. This especially applies when
driving downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of swaying . Never try to stabilise the trailer by accelerating.
Anticipate hazards and brake in good time. If towing a trailer with an inertia
brake , first brake gently and then harder. This will prevent brake tapping by
the trailer wheels when they lock. Select a low gear in due course before
going down a steep downhill. This enables you to use the engine braking to
slow down the vehicle.
Swaying and pitching can be reduced by stabiliser aids. We recommend
having stabiliser aids installed when towing trailers with a high trailer weight.
They can be purchased and installed at a Technical Service.
Reheating
When climbing long hills in hot weather with the engine running fast in low
gear, you should keep an eye on the coolant temperature gauge ⇒page 60.
Reduce speed immediately if the needle moves to the right end of the scale.
If the temperature warning lamp
v in the instrument panel should start
flashing, stop the vehicle and let the engine cool down by running it at idling
speed for a few minutes.

Vehicle maintenance and cleaning
216
Caution•Never remove dirt, mud or dust if the vehicle surface is dry. Never use a
dry cloth or sponge for cleaning purposes. This could scratch the paintwork
or glass on your vehicle.•Washing the vehicle in low temperatures: when washing the vehicle with
a hose, do not direct water into the lock cylinders or the gaps around the
doors, tailgate, or sunroof. Risk of freezing.For the sake of the environment
To protect environment, the vehicle should be washed only in specially
provided wash bays. This prevents toxic, oil-laden waste water entering the
sewerage system. In some places, washing vehicles outside wash bays is
prohibited.
Note
Do not wash the vehicle in direct sunlight.Washing the vehicle with a high pressure cleaner
Be particularly careful when using a high pressure cleaner!– Always observe the instructions for the high-pressure cleaner,
particularly those concerning the pressure and the spraying
distance.
– Increase the spraying distance for soft materials and painted bumpers.
– Do not use a high pressure cleaner to remove ice or snow from windows ⇒page 217. – Never use concentrated jet nozzles (“rotating jets”)
⇒.
– After washing, avoid sudden and sharp braking. Dry the brakes by braking several times ⇒page 197.
WARNING
•Never wash tyres with a concentrated jet (“rotating nozzle”). Even at
large spraying distances and short cleaning times, visible and invisible
damage can occur to the tyres. This may cause an accident.•Water, ice and salt on the brakes can reduce braking efficiency. Risk of
accident.Caution
•Do not use water hotter than 60 °C. This could damage the vehicle.•To avoid damage to the vehicle, keep a sufficient distance from sensitive
materials such as flexible hoses, plastic, soundproofing material, etc. This is
also important for bumpers painted in the colour of the bodywork. The closer
the nozzle is to the surface, the greater the wear on the material.Vehicle paint maintenance
Regular waxing protects the paintwork.You need to apply wax to your vehicle if water does not form small drops and
run off the paintwork when it is clean .
Good quality hard wax products are available at your Authorised Service
Centre.
