XIf appropriate for the driving conditions,
engage the LOW RANGE off-road gear
( Y page 132).
Traction control is part of ESP ®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP ®
.
Traction control is no longer active above a
speed of approximately 37 mph (60 km/h).

Deactivating/activating ESP®
iObserve the "Important safety notes" sec-
tion ( Ypage 64).
GWARNING
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 descri-
bed in the following.
!Avoid spinning the driven wheels for an
extended period with ESP ®
deactivated.
You could otherwise damage the drivetrain.
X To deactivate: press button:until the
å warning lamp lights up in the instru-
ment cluster.
X To activate: press button :until the å
warning lamp goes out in the instrument cluster.
ESP ®
is activated automatically when the
engine is started.
iVehicles with the ECO start/stop func-
tion: the ECO start/stop function automat-
ically switches the engine off when the
vehicle comes to a stop. The engine starts
automatically when the driver wants to pull
away again. ESP ®
remains in its previously
selected status. For example, if ESP ®
was
deactivated before the engine was
switched off, ESP ®
remains deactivated
when the engine is switched on again.
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
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R the engine's torque is no longer limited and
the drive wheels can spin. The spinning of
the wheels results in a cutting action, which
provides better grip.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
R and are driving at above 37 mph (60 km/h)
(on AMG vehicles above 62 mph
(100 km/h)), ESP ®
still intervenes when
one wheel reaches its grip limit even
though it is deactivated.
iIf ESP ®
is deactivated and one or more
wheels start to spin, the ÷warning lamp
in the instrument cluster flashes. In such
situations, ESP ®
will not stabilize the vehi-
cle.

iIf ESP®
is deactivated, it is reactivated
automatically if you are driving at above
37 mph (60 km/h) (on AMG vehicles above
62 mph (100 km/h)) or you exceed a cer-
tain lateral acceleration.
Trailer stabilization
GWARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent the vehicle/trailer combination from swerv-
ing. Trailers with a high center of gravity can
tip over before ESP ®
can detect this. There is
a risk of an accident.
Always adapt your driving style to the prevail- ing road and weather conditions.
Trailer stabilization does not work if ESP ®
is
deactivated because of a malfunction.
If your vehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
In this situation, ESP ®
assists you and can
detect if the vehicle/trailer combination
begins to lurch. ESP ®
slows the vehicle down
by braking and limiting the engine output until the vehicle/trailer combination has stabi- lized.
Trailer stabilization is active above speeds of
about 37 mph (60 km/h).
EBD (electronic brake force distribu- tion)
iObserve the "Important safety notes" sec-
tion ( Ypage 64).
GWARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps ( Ypage 163) as well as dis-
play messages ( Ypage 148).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking.
ADAPTIVE BRAKE
ADAPTIVE BRAKE provides increased braking
safety. In addition to the braking function,
ADAPTIVE BRAKE also has the HOLD function
( Y page 126) and hill start assist
( Y page 105).

Important safety notes
GWARNING
Children could become trapped if they adjust
the seats, particularly when unattended.
There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Neverleave children unsupervised in the vehicle.
The seats can still be adjusted when there is
no SmartKey in the ignition lock.
GWARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat.
Observe the safety notes on "Air bags" ( Y page 48) and "Children in the vehicle"
( Y page 55).
GWARNING
You could lose control of your vehicle if you do
the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine.
GWARNING
If head restraints are not installed and adjus-
ted correctly, they cannot provide protection
as intended. There is an increased risk of
injury in the head and neck area, e.g. in the
event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head

restraint supports the back of the head at
about eye level.
Make sure that you do not rotate the head
restraints of the front and rear seats when
adjusting the head restraints. Otherwise, you cannot adjust the height and angle of the
head restraints correctly.
Adjust the head restraint so that it is as close as possible to your head.
GWARNING
You could lose control of your vehicle if you do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine.
GWARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,we strongly recommend that children be
placed in the rear seat whenever possible.
Regardless of seating position, children 12
years old and under must be seated and prop- erly secured in an appropriately sized child
restraint system or booster seat recommen-
ded for the size and weight of the child. For
additional information, see the "Children in
the vehicle" section.
A child's risk of serious or fatal injuries is sig-
nificantly increased if the child restraints are
not properly secured in the vehicle and/or the child is not properly secured in the child
restraint.
!To avoid damage to the seats and the seat
heating, observe the following information:
R keep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
R if the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not be used to dry
the seats.
R clean the seat covers as recommended;
see the "Interior care" section.
R do not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions, e.g. knives, nails or tools. The seats should only be occupied by
passengers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating mate- rials, e.g. blankets, coats, bags, seat cov-
ers, child seats or booster seats.
!Make sure that there are no objects in the
footwell under or behind the seats when
moving the seats back. There is a risk that
the seats and/or the objects could be dam-
aged.
!When the rear bench seat is folded for-
wards, the front seats cannot be moved to their rearmost position. You could other-
wise damage the seats and the rear bench
seat.
!Make sure that the sun visor is folded up
before adjusting the backrest and head
restraint height. The head restraint and sun visor could otherwise collide when the head
restraint is fully extended.
iIf the front door is open, the seats can be
adjusted for up to 30 minutes after the igni- tion has been switched off.
iThe rear-compartment head restraints
can be removed ( Ypage 84).
