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
backrest 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 belt would apply force at the ab-
domen 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 position that is as upright as
possible and belts are properly positioned
on the body.
Warning!G
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 53).
Observe the following points:
Adjust the backrest until your arms are
slightly angled when holding the steer-
ing wheel
Adjust the seat to a comfortable seating
position that still allows 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 be-
ing 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 or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle.
Even with the SmartKey or the SmartKey
with KEYLESS-GO* removed from the
starter switch or the SmartKey with
KEYLESS-GO* removed from the vehicle,
the power seats can be operated.
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.

button
2Adjustment button
3Passenger-side exterior rear view mir-
ror button
Switch on the ignition (page 42).
Press button1 for the driver’s side ex-
terior rear view mirror or button3 for
the passenger-side exterior rear view
mirror.
The indicator lamp on the respective
button comes on for
approximately 15 seconds.

15 seconds, the indicator lamp goes out. You will
then have to select the desired exterior rear view
mirror again before any adjustments can be
made. Adjustments can only be made with the
indicator lamp for the respective exterior rear
view mirror button illuminated.
!If an exterior rear view mirror was forcibly
pushed forward (hit from the rear) or forcibly
pushed rearward (hit from the front), reposition
it by applying firm pressure until it snaps into
place. The mirror housing is then properly posi-
tioned and you can adjust the mirror in the usual
manner.
!Vehicle with power folding exterior rear view
mirrors*:
If an exterior rear view mirror housing is forcibly
pushed forward (hit from the rear) or forcibly
pushed rearward (hit from the front), press fold
button1 (
page 210) to fold mirrors in, then
press fold button1 (
page 210) again to fold
mirrors out. Do not force mirrors by hand as this
may damage the adjustment mechanism.
The mirror housing is then properly positioned
and you can adjust the mirror in the usual man-
ner.
iThe memory function* (page 141) lets
you store the settings for the exterior rear view
mirrors together with the setting for the steering
wheel and the seat positions.
iAt low ambient temperatures, the exterior
rear view mirrors will be heated automatically.

Parking and locking
You have now completed your first drive.
You have properly stopped and parked
your vehicle. End your drive as follows.Parking brake
1Parking brake pedal
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 com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these 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.
Firmly depress parking brake pedal.
Shift the automatic transmission to
positionP.
Slowly release brake pedal.
When parked on an incline, turn front
wheel towards the road curb.
Turn the SmartKey in the starter switch
to position0 and remove the SmartKey
from the starter switch, or press the
start/stop button (vehicles with
KEYLESS-GO*).
Take the SmartKey or the SmartKey with
KEYLESS-GO* with you and lock vehicle
when leaving.
Warning!G
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 vehi-
cle’s brake lights do not light up when the
parking brake is engaged.

68 Getting started
Parking and locking
Step firmly on parking brake pedal1.
When the engine is running, the
warning lamp; (USA only) or3
(Canada only) in the instrument cluster
comes on.
Switching off headlamps
Turn the exterior lamp switch toM
(
page 61).
For more information, see “Lighting”
(
page 143).
Turning off the engine
Shift the automatic transmission to
positionP (
page 191).
Apply the parking brake (page 67).
Warning!G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Children could release the
parking brake and/or shift the automatic
transmission out of positionP, either of
which could result in an accident and/or
serious personal injury.
Warning!G
Getting out of your vehicle with the
automatic transmission not fully engaged in
positionP is dangerous. Also, when parked
on an incline, positionP alone may not
prevent your vehicle from moving, possibly
hitting people or objects.
Always set the parking brake in addition to
shifting to positionP (
page 191).
When parked on an incline, also turn front
wheel towards the road curb.
iIf the engine cannot be turned off as
described, see “Emergency engine shut-down”
(
page 545).
Warning!G
Do not turn off the engine before the vehicle
has come to a complete stop. With the en-
gine not running, there is no power assis-
tance for the brake and steering systems. In
this case, it is important to keep in mind that
a considerably higher degree of effort is nec-
essary to brake and steer the vehicle.
iAlways set the parking brake in addition to
shifting the automatic transmission to positionP
(
page 191).
When parked on an incline, also turn front wheel
towards the road curb.

102 Safety and Security
Driving safety systems
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 pul-
sation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and ability to steer
the vehicle.
The pulsating brake pedal can be an
indication of hazardous road conditions
and functions as a reminder to take extra
care while driving.Emergency brake maneuver
Keep continuous full pressure on the
brake pedal.
Off-road – ABS
With the off-road driving program switched
on (
page 277), or with the transmission
in LOW RANGE* mode (
page 201), the
ABS designed for off-road use is automati-
cally activated.
When applying the brakes at speeds below
approximately 18 mph (30 km/h), the
front wheels are locked cyclically to short-
en the braking distance (dig-in effect). This
affects steering the vehicle.
For more information, see “Practical hints”
(
page 435).
Warning!G
When the ABS is malfunctioning, the BAS,
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.
Warning!G
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency be-
yond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded. The ABS cannot prevent acci-
dents, including those resulting from
excessive speed in turns, following another
vehicle too closely, or hydroplaning. Only a
safe, attentive, and skillful driver can pre-
vent accidents. The capabilities of an ABS
equipped vehicle must never be exploited in
a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.
