bags
The air bags will not deploy in impacts which
do not exceed the system’s preset
deployment thresholds. You will then be
protected by the fastened seat belts.
The front air bags will not deploy in the event
of a rollover unless the vehicle’s rate of
longitudinal deceleration or acceleration
exceeds the preset deployment threshold for
the front air bags.
The front passenger front air bag will only be
deployed if
Rthe front passenger seat is occupied
Rthe 4/ indicator lamp in the center
console is not lit (Y page 36)
Rthe impact exceeds a preset deployment
threshold
! Do not place objects heavier than 20 lb
(9 kg) on the front passenger seat. This
could cause the front air bag on the front
passenger side to deploy in a crash which
exceeds the system’s deployment
threshold.
Window curtain air bags
GObserve Safety notes, see page 33.When deployed, window curtain air bags :
are designed to provide increased protection

GWarning!
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, the seat

Transfer case
For more information on off-road driving, see
“Off-road driving” (Y page 179).
Transfer case position
HHIGH
Road position
LLOW
Off-road position
This position is intended for
driving off-road and step
gradients.
The automatic transmission
will not upshift
automatically to the next
higher gear range when
driving at the rpm limit.
The transfer case supports
the engine’s driving force
(approximately 1/2 speed).
Output is therefore
increased.
NNeutral
No power is transmitted
from the engine to the drive
axle.
Switching transfer case
The transfer case switch is located on the
lower part of the center console.
Transfer case switch
Current transfer case indicator : appears in
the multifunction display.
GWarning!
Always wait until the procedure of shifting
from HIGH to LOW – and from LOW to HIGH
– has been entirely completed. During this
procedure do not turn off the engine or shift
the automatic transmission into another gear.
If you do not wait until the shifting procedure
has been entirely completed then it might not
be correctly performed. The transfer case
might be in neutral, thus interrupting the
transfer of power between the engine and the
drive axle.
The vehicle is then freely movable, even if a
gear has been selected, and could
unintentionally be set into motion –
particularly on up – or downhill grades. This

switches in sequential order (center, rear,
front) (Y page 94). When the transfer case
(center) differential is locked, half of the
engine’s power is automatically distributed to
the front wheels and half to the rear wheels.
When the rear differential is locked, power
going to the rear wheels is equally distributed,
so that both rear wheels turn at the same
speed and torque. Please be aware that
engaging the differential locks will
significantly reduce the steering ability of the
vehicle.
For your safety and the safety of others and
to prevent damage to the vehicle, the
differential locks must not be engaged when
driving on paved roads. It is important to
understand that during on-road/paved
driving, differentials are absolutely necessary
for providing the essential control and
steering ability of the vehicle. The differential
locks, therefore, must not be engaged when
driving on paved roads and should only be
used to the extent necessary to negotiate off-
road conditions which cannot be handled by
the systems (the 4-ETS, the ESP®, and the
manual switch position “LOW” of transfer
case) this vehicle comes equipped with.
Switching differential locks on and off
The switches are located on the upper part of

! To avoid damage to the transfer case and

RDo not engage the differential locks if the
driving wheels are spinning due to lack
of traction.
