for driving at a constant speed for extended
periods of time.

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
driving safety
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
R
driving 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. The
