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.
Starting out is possible on uphill grades up
to 30 %. The permissible side tilt is 30 %.▷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 control
systems 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.
Clear heavy soiling from the body.
General driving notes
Closing the tailgate WARNING
An open tailgate protrudes from the vehi‐
cle and can endanger occupants and other
traffic participants or damage the vehicle in the
event of an accident, braking or evasive ma‐
neuvers. In addition, exhaust fumes may enter
the vehicle interior. There is a risk of injury or
risk of property damage. Do not drive with the
tailgate open.◀
If driving with the tailgate open cannot be
avoided:▷Close all windows and the glass sunroof.▷Greatly increase the air flow from the vents.▷Drive moderately.
Hot exhaust system
WARNING
During driving operation, high tempera‐
tures can occur underneath the vehicle body,
e.g., caused by the exhaust gas system. If
combustible materials, such as leaves or grass,
come in contact with hot parts of the exhaust
gas system, these materials can ignite. There
is a risk of injury or risk of property damage.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that no combustible materials can come in
contact with hot vehicle parts in driving opera‐
tion, idle or during parking. Do not touch the
hot exhaust system.◀
Diesel particulate filter The diesel particulate filter collects soot parti‐
cles and burns them periodically at high tem‐
peratures.
During several minutes of cleaning the follow‐
ing may occur:
▷Temporarily, the engine may run less
smoothly.▷Noises and a slight amount of smoke com‐
ing from the exhaust until shortly after the
engine is shut down.▷A somewhat higher engine speed is neces‐
sary to reach usual performance.Seite 183Things to remember when drivingDriving tips183
