Getting started
Adjusting
 Adjusting
Seats
Warning!G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
the vehicle is put into motion.
Warning!G
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
back in an excessively reclined position as
this can be dangerous. You could slide
under the seat belt in a collision. If you slide
under it, the seat belt would apply force at
the abdomen or neck. That could cause
serious or fatal injuries.
The seat backrest and seat belts provide the
best restraint when the wearer is in a nearly
upright position and seat belts are properly
positioned on the body. Your seat must be
adjusted so that you can correctly fasten
your seat belt (
page 48).
Observe the following points:

Adjust the backrest until your arms are
slightly angled when holding the
steering wheel.

Adjust the seat to a comfortable seating
position that still a llows you to reach the
accelerator/brake pedal safely. The po-
sition should be as far back as possible
with the driver still able to operate the
controls properly.

Adjust the head restraint so that it is as
close to the head as possible and the
center of the head restraint supports
the back of the head at eye level.

Never place hands under the seat or
near any moving parts while a seat is
being adjusted.
Failure to do so could result in an accident
and/or serious personal injury.
Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle.
Even with the SmartKey removed from the
starter switch, the power seats can be
operated when the respective door is open.
Therefore, do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. A child’s unsupervised access to a
vehicle could result in an accident and/or
serious personal injury.

Warning!G
With the engine not running, there is no
power assistance for the brake and the
steering system. In this case, it is important
to keep in mind that a considerably higher
degree of effort is necessary to brake and
steer the vehicle.
Warning!G
Do not park this vehicle in areas where
combustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as thes e materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury or
damage to the vehicle drivetrain as a result
of vehicle movement, before turning off the
engine and leaving the vehicle always:

Keep right foot on brake pedal.

Pull the parking brake lever up as many
notches as possible.

Move the gear selector lever to park
position P.

Slowly release brake pedal.

wheels towards the road curb.

Turn the SmartKey in the starter switch
position 0 and remove.

Take the SmartKey with you and lock
vehicle when leaving.

Engaging the parking brake while the vehicle
is in motion can cause the rear wheels to
lock up. You could lose control of the vehicle
and cause an accident. In addition, the
vehicle’s brake lights do not light up when
the parking brake is engaged.

88 Safety and Security
Driving safety systems
Continuous steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to
steer the vehicle.
On slippery road surfaces, the ABS will
respond even to light brake pressure. The
pulsating brake pedal can be an indication
of hazardous road conditions and func-
tions as a reminder to take extra care while
driving.
The - indicator lamp in the instrument
cluster (
page 26) comes on when you
turn the SmartKey to position 2. It goes
out when the engine is running. Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating
that the ABS is in
the regulating mode.
Keep firm and steady pressure on the
brake pedal while experiencing the
pulsation. Emergency brake maneuver
Keep continuous full pressure on the
brake pedal.
Warning!G
When the ABS is malf
unctioning, the BAS,
the EBB, the ESP®, and the 4-ETS are also
switched off. The basic driving and braking
functions are still available.
When the ABS is malfunctioning, the wheels
may lock during hard braking, reducing
steering capability and extending the brak-
ing distance.

Differential locks
 Differential locks
For more information on off-road driving,
see “Off-road driving” (
page 253).
Differential locks improve the vehicle’s
tractive power off-road. Switch on
differential locks:

for off-road driving

to turn the ABS off during off-road
driving

for driving through water

when driving on deep snow and icy or
fouled surfaces
!Do not engage the front axle differential
lock when driving around tight corners. This
restricts steering ability.
!When driving off-road, apply only moderate
pressure to the accelerator pedal if the differen-
tial locks are switched on.
When running on a (single-axle) dynamometer –
no matter how briefly – you must:

raise the non-driven axle
or

disconnect its drive shaft
and

engage the transfer differential lock
Otherwise the transfer case can be damaged,
which is not covered by the Mercedes-Benz
Limited Warranty.
Warning!G
Never drive on pavement with differential
locks engaged.
Steering control will be strongly affected
with the differential locks activated.
The ABS, BAS, and ESP
® are switched off
