Driving systems
Overview
The following pages describe driving systems
that may be a component in your vehicle:
R
Cruise control (Y page 119) which you can
use to control the speed of your vehicle
R
PARKTRONIC (Y page 121) and the rear
view camera (Y page 124) which assist you
with parking and maneuvering
Cruise control
Important safety information
Cruise control maintains the speed of the
vehicle for you.
G
WARNING
Cruise control is unable to take account of
road and traffic conditions.
Always pay attention to the traffic conditions,
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are always responsible for the
vehicle's speed and for braking in good time.
If there is a change of drivers, make sure that
you inform the new driver about the set cruise
speed. Otherwise, sudden acceleration or
braking could endanger you or others.
G
WARNING
Do not use cruise control:
R
in road and traffic conditions which do not
allow you to maintain a constant speed (e.g.
heavy traffic or winding roads). You could
otherwise cause an accident.
R
on slippery roads. Braking or accelerating
could cause the drive wheels to lose
traction and the vehicle could then skid.
R
when there is poor visibility, e.g. due to fog,
heavy rain or snow.
Use cruise control if road and traffic
conditions make it appropriate to maintain a
steady speed for a prolonged period. You can
set any speed from 20 mph upwards in
increments of 1 mph.
i
If you have set km/h as the unit for the
digital speedometer (Y page 83), you can
set any speed from 30 km/h upwards in
increments of 1 km/h.
Cruise control may not be able to maintain
the stored speed on uphill or downhill
gradients. The stored speed is resumed if the
gradient evens out and the vehicle's speed
does not fall below 20 mph (30 km/h).
