50 Getting startedParking and locking
Parking and lockingYou have now completed your first drive.
You have properly stopped and parked
your vehicle. End your drive as follows.
Parking brake
1Parking brake
2Release handle
Step firmly on parking brake1.
When the engine is running, the indica-
tor lamp ; (USA only) or 3
(Canada only) in the instrument cluster
will be illuminated.
Warning!
G
Wait until the vehicle is stationary before re-
moving the key from the starter switch. The
vehicle cannot be steered when the key is
removed.Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to stop or steer the vehi-
cle.
Warning!
G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off
the engine and leaving the vehicle always:

Keep right foot on brake pedal.


Firmly depress parking brake pedal.


Move the selector lever to positionP.


Slowly release brake pedal.


When parked on an incline, turn front
wheel towards the road curb.


Turn the key to starter switch position0
and remove, or press start- / stop button
(vehicles with KEYLESS-GO*).


Take the key or the SmartKey with KEY-
LESS-GO* (if so equipped) and lock ve-
hicle when leaving.

79 Safety and Security
Driving safety systems
The SBC brake servo assistance switches
off automatically when you:

turn the key in the starter switch to
position0 or remove the key (after ap-
proximately two minutes)


lock the vehicle with the SmartKey
from outside (after approximately
20 seconds)
Note on driving with the SBC


Following extended periods of only mi-
nor loads to your brake system, you
should occasionally apply the brakes
when traveling at high speeds. This im-
proves the grip of the brake pads.
iIf the SBC brake system is activated
when the brake pedal is first de-
pressed, you may feel a reduced pedal
resistance and longer pedal travel than
normal. When releasing the pedal, you
may also feel the brake pedal pulsate
and you may hear a sound which is
caused by the activation of the SBC
pump. This is normal and not an indica-
tion of a malfunction. Pedal travel re-
turns to normal when you release the
brake pedal and the sound soon ceas-
es.
Warning!
G
Have brake pad replacement and other work
on the SBC brake system carried out by
qualified technicians only. Contact your au-
thorized Mercedes-Benz Center for further
information. The SBC brake system must be
deactivated prior to working on the system.
High pressure is intermittently built up in the
system as part of its automatic self-test. In
addition, the system is automatically acti-
vated when the vehicle is unlocked by re-
mote control, when the driver or passenger
door is opened, when the key in the starter
switch is turned to position1, when the
brake pedal is depressed or when the park-
ing brake is released. Failure to deactivate
the system prior to maintenance will cause
brake pistons to extend and brake fluid to
leak, which may result in injuries (contu-
sions and acid burns). Extended brake pis-
tons may also cause injury.
Warning!
G
Be very careful not to endanger other road
users when you apply the brakes.

194 Controls in detailDriving systems
Driving systemsThe following driving systems are ex-
plained on the following pages:

Cruise control


Distronic*


AIRMATIC DC*


Park assist (Parktronic*)
The BAS, ABS, ESP and SBC driving sys-
tems are described in the "Safety and Se-
curity" section (
page 73).
Cruise control
Cruise control automatically maintains the
speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time. You can set any speed
over 20 mph (30 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever found on the left-hand side of the
steering column (
page 20).
Warning!
G
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. The driver must always remain
responsible for the vehicle speed and for
safe brake operation.
Only use cruise control if the traffic and
weather conditions make it advisable to
travel at a steady speed.

The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.


The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.


Deactivate cruise control when driving
in fog.
The "Resume" function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

212 Controls in detailDriving systemsSuspension for sporty driving style I

ed.

Press button1 twice.
Two indicator lamps2 come on.
Suspension for regular driving style
The setting for regular driving is selected
when the two indicator lamps2 are off.

Press button1 repeatedly until all indi-
cator lamps go out.
The indicator lamps2 go out.
PARKTRONIC system*
The Parktronic system is an electronic aid
designed to assist the driver during park-
ing maneuvers. It visually and audibly indi-
cates the relative distance between the
vehicle and an obstacle.
The Parktronic system is automatically ac-
tivated when you switch on the ignition
and release the parking brake. The Park-
tronic system deactivates at speeds over
11 mph (18 km/h). At lower speeds the
Parktronic system turns on again.Warning!
G
Parktronic is a supplemental system. It is
not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always rests with the driver.
Special attention must be paid to objects
having smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or
street curbs). Such objects may not be de-
tected by the system and can damage the
vehicle.
The operational function of the Parktronic
can be affected by dirty sensors, especially
at times of snow and ice. See "Cleaning the
Parktronic system sensors" (
page 284).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers or the air
brakes of trucks) can cause the system to
send erratic indications, and should be tak-
en into consideration.
Warning!
G
Be sure that no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.
