angle
;
is maximum 25° when the vehicle is
loaded and ready to drive.
Loaded and ready to drive means: a full tank,
all fluids topped up and the driver is in the
vehicle.
R
Follow the line of fall when driving on slopes
and steep gradients.
R
Before driving on extreme uphill and down-
hill gradients, select the off-road drive pro-
gram*.
R
Observe the warnings for off-road driving
(
Y
page 158).
R
Drive slowly.
R
Accelerate gently and make sure that the
wheels are gripping.
R
Avoid high engine speeds, except when
driving on sandy and muddy routes with
high driving resistance.
R
Select a shift range appropriate to the gra-
dient.
R
Before tackling steep downhill gradients,
select shift range 1.
i
Depress the brake pedal when stopping
on steep uphill gradients. Hill start assist
will aid you when you pull away again
(
Y
page 84).
Maximum gradient-climbing capability
On good road surfaces, 70% of the maximum
gradient-climbing capability is available.
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 recognises this and brakes the
wheels accordingly. The rear wheel torque
is increased and it is easier to pull away.
Brow of hill
When driving up an uphill gradient, slightly
reduce pressure on the accelerator immedi-
ately before reaching the brow of the hill.
Make use of the vehicle’s own impetus to
travel over the brow.
This style of driving prevents:
R
the vehicle from lifting off the ground on the
brow of a hill
R
loss of traction
R
the vehicle from travelling too quickly down
the other side
Driving downhill
R
Drive slowly.
R
Do not drive at an angle down steep
inclines. Steer into the line of fall and drive
with the front wheels aligned straight. Oth-
erwise, the vehicle could slip sideways, tip
and overturn.
R
Before tackling steep downhill gradients,
select shift range 1.
R
Activate DSR. If this is not sufficient, brake
gently. When doing so, make sure that the
vehicle is facing in the direction of the line
of fall.
R
Check that the brakes are working normally
after a long downhill stretch.
i
Off-road ABS is activated when the off-
road drive program* is selected.
At speeds below 30 km/h, the front wheels
lock cyclically during braking. The digging-
in effect achieved in the process reduces
the stopping distance when driving off-
road. The steerability of the vehicle is con-
siderably reduced when the wheels lock.
Driving over obstacles
Observe the following rules when driving over
tree stumps, large stones and other obsta-
cles:
R
Select the off-road drive pro-
gram* (
Y
page 107).
R
Avoid high engine speeds.
