R
brow of a hill
the vehicle from traveling too quickly down
R
the other side
Driving downhill
Drive slowly.
R
Do not drive at an angle down steep
R
inclines. Steer into the line of fall and drive
with the front wheels aligned straight.
Otherwise, the vehicle could slip sideways,
tip and rollover.
Before tackling steep downhill gradients,
R
select shift range 1.
Activate DSR. If this is not sufficient, brake
R
gently. When doing so, make sure that the
vehicle is facing in the direction of the line
of fall.
Check that the brakes are working normally

Cruise control
Important safety notes
Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
select shift range 1, 2 or 3 in good time. By
doing so, you will make use of the braking
effect of the engine, which relieves the load
on the brake system and prevents the brakes
from overheating and wearing too quickly.
Use cruise control only if road and traffic
conditions make it appropriate to maintain a
steady speed for a prolonged period. You can
set any road speed above 20 mph
(30 km/h).
G
WARNING
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle's speed
and for safe brake operation.
Only use the cruise control if the road, traffic,
and weather conditions make it advisable to
travel at a constant speed.
The use of the cruise control can be
R
dangerous on winding roads or in heavy
traffic because conditions do not allow safe
driving at a constant speed.
The use of the cruise control can be
R
dangerous on slippery roads. Rapid
changes in tire traction can result in wheel
spin and loss of control.
Deactivate the cruise control when driving
R
in fog.
The "Resume" function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed.
G
WARNING
The cruise control brakes automatically so
that the set speed is not exceeded.
i Cruise control should not be activated
during off-road driving.
