ESP
®
is deactivated if the å warning lamp
in the instrument cluster is lit when the engine
is running.
Only use wheels with the recommended tire
sizes. Only then will ESP ®
function properly.
Deactivating or activating ESP ®G
WARNING
If you deactivate ESP ®
, ESP ®
no longer sta-
bilizes the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP ®
in the situations
described in the following.
It may be best to deactivate ESP ®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel
Activate ESP ®
as soon as the situations descri-
bed above no longer apply. Otherwise, ESP ®
assistance for stabilizing the vehicle will
remain significantly reduced, even if the vehi-
cle starts to skid.
If you deactivate ESP ®
:
R the å warning lamp in the instrument
cluster lights up
R the ÷ warning lamp in the instrument
cluster flashes if the wheels are spinning
R ESP ®
assistance for stabilizing the vehicle in
the lower speed range up to approximately
37 mph (60 km/h
) is significantly reduced
R engine torque is no longer limited and the
drive wheels are able to spin. The spinning
of the wheels results in a cutting action for
better traction on loose surfaces
R traction control is still activated
R ESP ®
still provides support when you brake
Depending on the equipment in the vehicle,
you can activate or deactivate ESP ®
when the
engine is running by using the å button or
by using the on-board computer:
R on vehicles without steering wheel buttons
(Y page 179)
R on vehicles with steering wheel buttons
(Y page 190) å button (equipment-dependent)
X To activate/deactivate: when the engine
is running, press the å button.
The å warning lamp in the instrument
cluster lights up when ESP ®
is deactivated.
Trailer stabilization Observe the important safety guidelines for
the driving safety system (
Y page

66). G
WARNING
If road and weather conditions are poor,
trailer stabilization will not be able to pre-
vent the vehicle/trailer combination from
swerving. Trailers with a high center of grav-
ity can tip over before ESP ®
can detect this.
There is a risk of an accident.
Always adapt your driving style to the pre-
vailing road and weather conditions.
ESP ®
trailer stabilization counteracts critical
driving situations in good time and thereby
provides considerable assistance when driving
with a trailer. Trailer stabilization is part of
ESP ®
.
If the sensor system and evaluation logic
detect trailer swinging movements, ESP ®
trailer stabilization firstly brakes individual
vehicle wheels in a targeted manner. It thus
counteracts swinging movements. If the
swinging movements do not stop, the vehicle
is braked until the vehicle/trailer combination
is stabilized. If necessary, the vehicle's engine
output is limited.
If your vehicle with trailer (vehicle/trailer com-
bination) starts to swerve, you will be able to
stabilize the vehicle/trailer combination only
by braking. ESP ®
trailer stabilization helps you Driving safety systems
69
Safety Z

to stabilize the vehicle/trailer combination in
this situation.
ESP
®
trailer stabilization is activated above
speeds of about
40 mph (65 km/h).
If ESP ®
is switched off or deactivated because
of a malfunction, the trailer stabilization sys-
tem will not function.
Crosswind Assist Observe the important safety guidelines for
the driving safety system (Y page

66).
Strong crosswind gusts can impair the road-
holding of your vehicle when driving straight
ahead. The Crosswind Assist function integra-
ted in ESP ®
reduces these impairments.
Depending on the direction and intensity of
the side wind, Crosswind Assist intervenes
automatically. ESP ®
intervenes with stabilizing
braking to assist you in keeping the vehicle in
the lane. When Crosswind Assist intervenes,
the display shows the traffic sign for strong
side winds and the Crosswind Assist mes-
sage.
Crosswind Assist is activated automatically
above a vehicle speed of approx. 50 mph
(80 km/h) when the vehicle is driving straight
ahead or cornering gently.
Crosswind Assist does not react in the follow-
ing situations:
R in the event of severe jolts and vibrations,
e.g. when driving over uneven surfaces or
potholes
R when road adhesion is reduced, e.g. on
snow or ice or when hydroplaning
Crosswind Assist does not work if ESP ®
is
deactivated or disabled because of a malfunc-
tion. Theft deterrent locking system
Immobilizer
X To activate: remove the key from the igni-
tion lock.
X To deactivate: turn the key to position 2 in

The immobilizer prevents your vehicle from
being started without the correct key.
Always take the key with you and lock the
vehicle when leaving the vehicle. If you leave the key in the vehicle, anyone can start the
engine.
i The immobilizer is always deactivated
when you start the engine. ATA (Anti-Theft Alarm system)

Visual check of the vehicle exterior X
In particular, check the following compo-
nents on the vehicle, and on the trailer as
necessary:
R
license plates, vehicle lighting, turn sig-
nals, brake lamps and wiper blades for
dirt and damage
R tires and wheels for firm seating, correct
tire pressure and general condition
R trailer tow hitch for play and security
The trailer coupling is one of the most
important vehicle parts with regard to
road safety. Observe the notes on opera-
tion, care and maintenance of the trailer
tow hitch (see the manufacturer's operat-
ing instructions).
X Rectify any noticeable defects before com-
mencing the journey. Checks in the vehicle Emergency equipment/first-aid kit
X Check the equipment to make sure that it is
accessible, complete and ready for use.
The first aid and breakdown assistance equip-
ment is located:
R in the front door stowage compartments
R in the seat base of the left front seat
R in the rear stowage compartment on the
right-hand side of the vehicle
(Y page 270)
Vehicle lighting
X Turn the key to position 2 in the ignition
lock.
X Check the lighting system with the aid of a
second person.
X Replace defective bulbs (Y page

G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardizes the oper-
ating and road safety of the vehicle. There is
a risk of an accident.
Stow all objects securely in the vehicle so
that they do not get into the driver's foot-
well. When using floormats or carpets, make
sure that they are properly secured so that
they do not slip or obstruct the pedals. Do
not place several floormats or carpets on
top of one another. G
WARNING
Unsuitable footwear can hinder correct
usage of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. Driving
