R Comply with the rules for off-road driving.
R
Do not drive at an angle on slopes, inclines
or gradients, but instead follow the direct
line of fall. The maximum gradient-climbing
capability of your vehicle is 100%, which
corresponds to an approach/departure
angle of 45°. Note that the vehicle's
gradient-climbing capability depends on
the off-road conditions.
R
Before tackling steep downhill gradients,
select shift range
1.
R
Drive slowly.
R
Avoid high engine speeds – drive at a
suitable engine speed (maximum 3000
rpm).
R Use the braking power of the engine when
driving down a slope. Observe the engine
speed, do not overrev the engine.
R Check the brakes after driving off-road for
a long time.
G Warning!
Never turn the vehicle around on steep
inclines. The vehicle might roll over. If the
vehicle cannot complete the attempted climb,
back it down in reverse gear.
i Hill start assist will aid you when pulling
away on a hill.
For more information, see "Hill start assist"
(
Y page 142).
Maximum gradient climbing ability
On good road surfaces, the maximum
gradient climbing capability of your vehicle is
100%, which corresponds to an approach/
departure angle of 45°. Note that the
vehicle's gradient-climbing capability
depends on the off-road conditions.
Accelerate carefully and make sure that the
wheels do not spin when driving on steep
terrain.
i If the load on the front axle is reduced
when pulling away on a steep uphill slope,
the front wheels have a tendency to spin.
4ETS recognizes this and brakes the
wheels accordingly. The rear wheel torque
is increased and it is easier to pull away.
