Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops collecting under‐
neath the vehicle.
These traces of water under the vehicle are
normal.
Driving on poor roads The vehicle combines all-wheel drive with the
advantages of a normal automobile.
CAUTION
Objects in unpaved areas, e.g. stones or
branches, can damage the vehicle. There is
risk of property damage. Do not drive on un‐
paved terrain.◀
For your own safety, for the safety of passen‐
gers and of the vehicle, heed the following
points:▷Become familiar with the vehicle before
starting a trip; do not take risks in driving.▷Adjust the speed to the road surface con‐
ditions. The steeper and more uneven the
road surface, the slower the speed should
be.▷When driving on steep uphill or downhill
grades: add engine oil and coolant up to
near the MAX mark. Uphill and downhill
grades can be traveled up to no more than
50 %.▷On steep downhill grades, use Hill Descent
Control HDC, refer to page 140.
Starting out is possible on uphill grades up
to 32 %. The permissible side tilt is 50 %.▷Avoid that the chassis bottom coming in
contact with the ground.
The ground clearance is no more than 7.8
inches/20 cm and can vary according to
the vehicle's load.▷When wheels continue to spin, depress the
accelerator so that driving stability controlsystems can distribute the driving force to
the wheels. Activate DTC Dynamic Trac‐
tion Control if available.
After a trip on poor roads
After a trip on poor roads, check wheels and
tires for damage to maintain driving safety.

center or another qualified service center or re‐
pair shop.◀
Light-emitting diodes (LEDs)
Some items of equipment use light-emitting
diodes installed behind a cover as a light
source.
These light-emitting diodes, which are related
to conventional lasers, are officially designated
as Class 1 light-emitting diodes.
WARNING
Too intensive brightness can irritate or
damage the retina of the eye. There is risk of
injuries. Do not look directly into the headlights
or other light sources for an extended period of
time. Do not remove the LED covers.◀
Headlight glass
Condensation can form on the inside of the ex‐
ternal lights in cool or humid weather. When
driving with the lights switched on, the con‐
densation evaporates after a short time. The
headlight glass does not need to be changed.
If despite driving with the lights switched on,
increasing humidity forms, e. g. water droplets
in the lamp, the manufacturer of your vehicle
recommends having it checked by a dealer’s
service center or another qualified service cen‐
ter or repair shop.
Headlight setting The headlight adjustments can be affected by
changing lights and bulbs. After the headlight
adjustment was changed, have it checked and,
if necessary, corrected by a dealer’s service
center or another qualified service center or re‐
pair shop.Front lights, bulb replacement
Xenon headlights
Information
Because of the long service life of these bulbs,
the likelihood of failure is very low. Switching
the lights on and off frequently shortens their
service life.
If a bulb fails, turn on the front fog lights and
continue the trip with great care. Comply with local regulations.
DANGER
There can be high voltage in the lighting
system. There is danger to life. The manufac‐
turer of your vehicle recommends that the work on the lighting system including bulb re‐
placement be performed by a dealer’s service
center or another qualified service center or re‐
pair shop.◀
For checking and adjusting headlamp aim,
contact a dealer’s service center or another
qualified service center or repair shop.
