Cruise control maintains the speed of
the vehicle for you.
Use cruise control if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period.
You can set any speed above 20 mph
(30 km/h) in 1-mph increments (1-km/
h increments).Cruise control*
iThe increments for setting speed and
the threshold values for switching on
or automatically switching off cruise
control depend on the digital speed-
ometer setting, mph or km/h
(\2

Cruise control leverThe cruise control lever is the upper-
most lever on the left of the steering col-
umn.
Warning
G
The cruise control function cannot take
account of road and traffic conditions.
Always pay attention to road and traffic
conditions, even when cruise control is
activated.Cruise control is only an aid designed to
assist driving. You are responsible for the
vehicle’s speed and for braking in good
time.
If there is a change of drivers, advise the
new driver of the cruising speed that is
stored.
Warning
G
Do not use cruise control:
\4if road and traffic conditions do not
permit a constant driving speed to be
maintained (e.g. heavy traffic or wind-
ing roads). You could otherwise cause
an accident.
\4on slippery roads. The drive wheels
may lose their grip when braking or
accelerating and the vehicle could
skid
\4when visibility is poor, e.g. in fog,
heavy rain or snow
iCruise control may be unable 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
has not fallen below 20 mph
(30 km/h).

Warning
G
Only resume the stored speed if you know
what this speed is and the current situa-
tion is appropriate to do so. Otherwise,
sudden acceleration or braking could en-
danger you or others.
iWhen you pull the cruise control le-
ver in direction of arrow

for the
first time after starting the engine,
cruise control is switched on and the
speed at which you are currently
driving is stored.
Warning
G
The rate at which you increase the speed
in 1 mph increments (1 km/h increments)
may be faster than your vehicle is able to
accelerate. Your vehicle may then contin-
ue to accelerate up to the newly set speed
even after you have released the cruise
control lever.
Only increase the speed if the current sit-
uation is appropriate to do so. Sudden ac-
celeration could otherwise endanger you
and others.

Warning
G
Parktronic is only an aid and may not de-

relieve you of the need to pay attention.
You are always responsible for safety and
must continue to pay attention to your im-
mediate surroundings when parking and
maneuvering. Otherwise, you could en-
danger yourself and others.
Warning

Make sure that no persons or animals are
in the maneuvering range of the vehicle.
They could otherwise be injured.

Parktronic is an electronic parking aid
and informs you visually and audibly of
the distance between the vehicle and an
obstacle.
Parktronic is automatically switched on
when you switch on the ignition and re-
lease the handbrake. You must also
move the selector lever to position
D, N
or R.
Parktronic switches off at speeds of over
11 mph (18 km/h). It switches on again
as soon as the vehicle’s speed falls be-
low this limit speed.
Parktronic is equipped with sensors in
the front and rear bumper to monitor the
area around your vehicle.
Range of the sensorsThe sensors must be free from dirt, ice
and slush, otherwise they may not func-
tion correctly. Clean the sensors regu-
larly, taking care not to scratch or
damage them (
