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 137.
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 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.
