then you should switch on the ESP again.
WARNING
It is also not possible for the ESP to overcome the physical limits of the vehicle. Even if a vehicle fitted with ESP you should still always adapt your style of driving to the condition of the
road surface and the traffic situation.
This particularly applies when driving on slippery and wet roads. The increased safety offered must not tempt you to take greater risks than other- wise - risk of an accident!
Note
•
All four wheels must be fitted with the same tyres in order to achieve problem-
free operation of the ESP. Differing rolling
circumferences of the tyres can lead to an
undesirable reduction in the engine output.•
Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can influence the function of the ESP
⇒page 179,
“Accessories, changes and replacement of parts”.Electronic Differential Lock (EDL)* The electronic differential lock pr
events an individual wheel from
slipping.Vehicles fitted with ABS*
can be equipped with electron
ic differential lock (EDL).
General The EDL makes it much easier, and sometimes at all possible, to start off, accelerate and climb a steep hill when the conditio
ns of the road surface are unfavourable.
Operating principle The EDL is activated automatically, that is
without any action on the part of the
driver. It monitors the speeds of the driven wheels with the aid of the ABS sensors. Should only
one
drive wheel begin spinning on a slippery surface there will be an
appreciable difference in the speed of the driven wheels. The EDL function brakes the slipping wheel and the differential transmits a greater driving force to the other driven wheel. This control proces
s is also accompanied by noises.
Overheating of the brakes The EDL switches off
automatically if unusually severe
stresses exist in order to
avoid excessive heat generation in the
disc brake on the wheel which is being
braked. The vehicle can continue to be driv
en and has the same characteristics as a
vehicle not fitted with EDL. The EDL switches on again
automatically as soon as the brake has cooled down.
WARNING
•
Carefully depress the accelerator when accelerating on uniformly slip-
pery road surfaces, such as ice and sn
ow. The driven wheels might still spin
despite the EDL and affect the stability
of the vehicle - risk of an accident!
•
You should always adapt your style of driving to the condition of road
surface and to the traffic situation even
when your vehicle is fitted with EDL.
The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!
Note
•
If the ABS warning light comes on, this ma
y also indicate a fault in the EDL.
Please have the vehicle inspected as soon
as possible by a specialist garage.

Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can in

Wet roads or road salt There may be a certain delay before the br
akes take full effect under certain condi-
tions such as when driving through water,
during heavy rain
showers or after the
vehicle has been washed in
an automatic vehicle wash, since the brake discs and
brake pads may be moist or even have a
coating of ice on them in winter. You
should dry the brakes as soon as possib
le by applying and releasing the brakes
several times. There also may be a certain delay before the
full braking efficiency is available when
driving on roads which have been treated wi
th road salt if yo
u have not used the
brakes for some considerable time beforeha
nd. The layer of salt on the brake discs
and brake pads must first be rubb
ed off when you apply the brakes.
Corrosion Corrosion on the brake discs and dirt on th
e bake pads occur if
the vehicle has been
parked for a long period and if you do
not make much use of the braking system.
We recommend cleaning the brake discs by
firmly applying the brakes at a fairly
high speed if you do not make much use of the braking system or if surface corro-sion is present
⇒
.
Faults in the brake surface If you notice that the braking distance has suddenly become longer and that the brake pedal can be depressed further, it is
possible that a brake circuit of the dual-
circuit brake system has failed. Drive, in such cases, to the nearest specialist garage without delay in order to have the problem rectified. Drive at a reduced speed while on your way to the dealer and adapt your style of driving to the higher brake pedal pressure required. Low brake fluid level An insufficient level of brake fluid may result in problems in the brake system. The level of the brake fluid is monitored electronically
⇒page 34, “Brake system
”.
WARNING
•
Only apply the brakes for the purpose of drying and cleaning the brake
discs if the traffic conditions permit this. Do not place any other road users in jeopardy.
•
When retrospectively mounting a front
spoiler, solid wheel hubs etc. one
must ensure that the air supply to the front wheel brakes is not reduced otherwise the braking sy
stem could run too hot.
•
Allow for the fact that new brake pads
do not achieve th
eir full braking
efficiency until approximately 200 kilo
metres. New brake pads must be first
“run in” before they develop their optimal friction force. You can, however, compensate for this slightly reduced
braking force by increasing the pres-
sure on the brake pedal. This guidelin
e also applies to any new brake pads
installed at a future date.
Caution
•
Never allow the brakes to ru
b by applying slig
ht pressure if you do not wish to
brake the vehicle. This causes the brakes to overheat and can also result in a longer braking distance and excessive wear.•
Before negotiating a steep downhill section, reduce your speed, shift down into
the next lower gear. This enables you to make full use of the braking power of the vehicle and reduces the strain on the brakes
. Any additional braking should be done
intermittently, not continuously.Brake boosterThe brake booster boosts the pressure which you generate with the brake pedal. The necessary pressure is only gene
rated when the engine is running.
WARNING
•
Never switch off the engine befo
re the vehicle is stationary.
•
The brake booster only operates when
the engine is running. Greater
physical effort for braking is required
when engine is swit
ched off. Because
if you do not stop as normal, this can cause an accident and severe injuries.

should be attached to folding arms. Adjust
the mirrors so that they provide you with
an adequate field of view to the rear. Headlights Before starting off with a hitched trailer, also check the setting of the headlights. Alter the setting as necessary with th
e aid of the headlight beam adjuster
⇒ page 51. Detachable ball head The ball rod is detachable on vehicles which feature a factory-fitted towing device. It is stowed together with separate fitting instructions in the spare wheel well in the luggage compartment of the vehicle. Further information on the towing device
⇒page 146.
Note
•
We recommend that you also have yo
ur vehicle inspected between service
intervals if you tow a trailer frequently.•
The handbrake on the towing vehicle
must be put on when coupling and
decoupling the trailer.Driving Tips Particular caution is required when towing a trailer.– Do not, as far as possible, drive
with your vehicle unladen and the
trailer laden.
– Do not make full use of the legal maximum speeds. This applies in
particular to downhill sections.
– Apply the brakes in good time.– Keep a check on the coolant temper
ature gauge if the outside temper-
ature is high.
Distribution of weight The distribution of the weight is very poor
if your vehicle is
unladen and the trailer
is laden. Maintain a particularly low speed if you cannot avoid driving with this combination. Driving speed Do not drive faster than 80 km/hour for safety reasons. This also applies for coun- tries in which higher speeds are allowed. The fact that the driving stability of the vehicle + trailer combination reduces with increasing speed means that the legally allowed speed should not be used when there are unfavourable road, weather or wind
conditions, particul
arly near accident
black spots. You must always reduce your speed immedi
ately as soon as you detect even just
the
slightest swaying
of the trailer. On no account attempt to stop the trailer from
“swaying” by
accelerating.
Apply the brakes in good time! If the trailer is fitted with a
trailer brake
, apply the
brakes gently at first and then brake firmly
. This will avoid brake jolts resulting from
the trailer wheels locking. Shift down gears
in good time before negotiating a down-
hill section to allow the engine to also act as a brake. Engine overheating Please keep a check on the coolant temperature gauge if you have to negotiate a lengthy slope in a low gear at a high engine speed when the outside temperature is very high
⇒page 16.
If the needle of the coolant temperature gauge moves into the right-hand area or even the red area of the scale, reduce yo
ur speed immediately. Stop and switch off
the engine if the warning light
 in the instrument cluste
r begins flashing. Wait a
few minutes and check the level of coolant in the coolant expansion bottle ⇒ page 165, “Inspecting the coolant level”. Please refer to the following guidelines
⇒page 30, “Coolant temperature/ Coolant
quantity
”.
The coolant temperature can be reduced by switching on the heating.Any increase in the cooling effect of the coolant fan through shifting down a gear and increasing the engine speed is not possible since the fan speed is independent

WARNING
Pay attention to any legal requirements if
you do carry a spare canister in the
vehicle. We do not recommend carrying any fuel canisters in your vehicle for safety reasons. The canister can be da
maged in the event of an accident and
fuel may leak out.
Caution
•
Before refuelling it is necessary to switch off the auxiliary heating system (auxil-
iary heating and ventilation) *.•
Remove any fuel which has spilled onto
the paintwork of your vehicle immedi-
ately - risk of paint damage!•
On vehicles fitted with a
catalytic converter, never let the fuel tank run
completely empty. An irregular supply of fu
el to the engine can result in misfiring
and unburnt fuel may get into the exhaust system, which may result in overheating and damage to the catalytic converter.•
Make sure that the valve is not pressed
into the filler tube when inserting the
pump nozzle into the filler tube. Otherwis
e you are unintentionally filling up the
volume, which in case of heat can cause an
expansion of the fuel. This can lead to
an overflow of fuel or damage
to parts of the fuel reservoir.
•
The fuel tank is full just as soon as the pump nozzle switches off for the first time,
provided the nozzle has been operated pr
operly. Do not continue refuelling -
otherwise the expansion volume is filled up.Emergency release of fuel filler flapIf a fault exists in the system for opening the fuel filler flap from the driver's seat*, the fuel filler flap can be opened manually.
