as you close the sliding sunroof.
The glass may shatter in the event of an ac-
cident.
If you or other occupants are not wearing
your seat belt, there is a risk of being thrown
out of the opening in the event of the vehicle
overturning. Therefore, always wear a seat
belt to reduce the risk of injuries.
In accidents in which the vehicle overturns,
there is an increased risk of injury even for
occupants who have fastened their seat
belts correctly, as their head or limbs could
be thrust through the opening.
Remove the key from the ignition lock even
if you are only leaving the vehicle for a short
time.

CAUTION
Do not raise the sliding sunroof if you
have mounted a roof rack. It would oth-
erwise strike the roof rack.
You could thereby damage the sliding
sunroof and the roof rack.
iThe sliding sunroof opens automatical-
ly when you press the sliding sunroof
switch for opening beyond the pressure
point and then release it.
To stop the sliding sunroof, press the

\3 Driving systemsDriving systems which may form part of
your vehicle are described on the following
pages:
\4Cruise control* (\2page 147), which
you can use to control the speed of
your vehicle
\4Parktronic system*, which is an aid for
parking and maneuvering
(\2page 150)
\4Reverse warning feature*, which helps
you ensure the safety of other road us-
ers (\2page 153)
The ABS, BAS, ESP
®, ASR and EBV driving
safety systems are described in the "Safe-
ty and Security" section (\2page 23).Cruise control maintains the speed of the
vehicle for you.
Use cruise control if road and traffic condi-
tions make it appropriate to maintain a
steady speed for a prolonged period. You
can store any road speed above 20 mph
(30 km/h).
Cruise control*iThe increments for setting speed and
the threshold values for switching on or
automatically switching off cruise con-
trol depend on the digital speedometer
setting, mph or km/h (\2page 99).Warning
G
The cruise control function cannot take ac-
count of road and traffic conditions.
Always pay attention to road and traffic
conditions, even when cruise control is acti-
vated.
Cruise control is only an aid designed to as-
sist driving. You are responsible for the vehi-
cle’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 per-
mit a constant driving speed to be main-
tained (e.g. heavy traffic or winding
roads). You could otherwise cause an
accident.
\4on slippery roads. The drive wheels may
lose their grip when braking or acceler-
ating and the vehicle could skid
\4when visibility is poor, e.g. in fog, heavy
rain or snow

You cannot activate cruise control if:
\4you are driving under 20 mph

\4you are braking
\4you apply the handbrake and the7
indicator lamp in the instrument cluster

\1Release the accelerator pedal.
Cruise control is activated and adjusts
the vehicle’s speed to the last speed
stored.
iCruise control may be unable to main-
tain the stored speed on uphill or down-
hill 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 situation
is appropriate to do so. Otherwise, sudden
acceleration or braking could endanger you
or others.iWhen you pull the cruise control lever in
direction of arrow 2 for the first time
after starting the engine, cruise control
is switched on and the speed at which
you are currently driving is stored.

Setting the speed
\1Briefly press the cruise control lever
upward1 to increase the speed or
downward3 to reduce the speed.
The last speed stored is increased or
decreased in 1 mph increments
(1 km/h increments).
or
\1Press and hold the cruise control lever

The current speed is stored.
Deactivating cruise control
There are various ways of deactivating
cruise control:
\1Briefly press cruise control lever
forward4.
or
\1Apply the brakes.
The last speed set remains 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 accel-
erate. Your vehicle may then continue to ac-
celerate up to the newly set speed even
after you have released the cruise control le-
ver.
Only increase the speed if the current situa-
tion is appropriate to do so. Sudden acceler-
ation could otherwise endanger you and
others.
iCruise control is not deactivated if you
depress the accelerator pedal. If you ac-
celerate briefly to overtake, for exam-
ple, cruise control adjusts the vehicle’s
speed to the last speed stored after you
have finished overtaking.iThe last speed stored is cleared when
you switch off the engine.
iCruise control is automatically deacti-
vated if:

Parktronic is an electronic parking aid and
informs you visually and audibly of the dis-
tance between the vehicle and an obsta-
cle.
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). Parktronic switches on
again as soon as the vehicle’s speed falls
below this limit speed.
Parktronic is equipped with sensors in the
front and rear bumper to monitor the area
around your vehicle.Range of the sensors
The sensors must be free from dirt, ice and
slush, otherwise they may not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them
(\2page 244).
Parktronic system (PTS)*Warning
G
Parktronic is only an aid and may not detect
all obstacles. This system does not 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 endan-
ger yourself and others.Warning
G
Make sure that no persons or animals are in
the maneuvering range of the vehicle. They
could otherwise be injured.
