iWhen you switch on the ignition, the
indicator and warning lamps in the
instrument cluster come on. This indi-
cates that the respective systems are
operational. They should go out when
the engine is running.iThe SmartKey can only be removed
from the starter switch with the gear
selector lever in positionP.
!If the SmartKey cannot be turned in the
starter switch, the battery may not be
sufficiently charged.
Check the battery and charge it if
necessary (
page 347)
Get a jump start (
page 350).
To prevent accelerated battery
discharge and a possible dead battery,
always remove the SmartKey from the
starter switch when the engine is not in
operation.

48 Getting startedDriving
Release parking brake by pulling on
handle1.
The warning lamp; (USA only)
or3 (Canada only) in the
instrument cluster goes out.
Driving
Depress the brake pedal.
Move gear selector lever to positionD
orR.
Release the brake pedal.
Carefully depress the accelerator.
Once the vehicle is in motion, the auto-
matic central locking system engages
and the locking knobs drop down.After a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter to reach
its operating temperature earlier.iWait for the gear selection process to
complete before setting the vehicle in
motion.
iYou can open a locked door from the
inside. Open door only when conditions
are safe to do so.
You can deactivate the automatic
locking using the control system
(page 143).
!Simultaneously depressing the
accelerator pedal and applying the
brake reduces engine performance and
causes premature brake and drivetrain
wear.!If you hear a warning signal when driv-
ing off, you have forgotten to release
the parking brake.
Release the parking brake.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.!Place the gear selector lever in
positionR only when the vehicle is
stopped in order to avoid damaging the
transmission.!Do not run cold engine at high engine
speeds. Running a cold engine at high
engine speeds may shorten the service
life of the engine.

Warning!
G
It is dangerous to shift the gear selector
lever out ofP orN if the engine speed is
higher than idle speed. If your foot is not
firmly on the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal.

Parking and locking
Parking and locking
You have now completed your first drive.
You have properly stopped and parked
your vehicle. End your drive as follows.
Parking brake
1Release handle
2Parking brake
Step firmly on parking brake pedal2.
When the engine is running, the
warning lamp; (USA only)
or3(Canada only) in the
instrument cluster will be illuminated.
Warning!
G
Wait until the vehicle is stationary before
removing the SmartKey from the starter
switch. The vehicle cannot be steered when
the SmartKey is removed.Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
system. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle.
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 gear selector lever to
positionP.
Slowly release brake pedal.
When parked on an incline, turn front
wheels towards the road curb.
Turn the SmartKey in the starter switch
to position0 and remove the SmartKey
from the starter switch.
Take the SmartKey and lock vehicle
when leaving.

60 Safety and SecurityOccupant safetyIn this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
The restraint systems are
Seat belts
Emergency tensioning device
Air bags
Child seats
Child seat recognition
Lower anchors and tethers for children
(LATCH)
As independent systems, their protective
effects work in conjunction with each
other.The1 indicator lamp in the instrument
cluster (
page 24) comes on:
for about four seconds when you turn
the SmartKey in the starter switch to
position1. It then goes out briefly,
comes on again and remains lit until
you start the engine.
for about four seconds when you start
the engine by turning the SmartKey.The1 indicator lamp goes out shortly
after you start the engine. This shows that
the restraint systems are operational.
A malfunction in the system has been
detected if the1 indicator lamp:
fails to extinguish after approximately
four seconds.
does not come on at all.
comes on after the engine was started
or while driving.
For safety reasons, we strongly recom-
mend that you visit an authorized
Mercedes-Benz Center immediately to
have the system checked.
For more information, see “Practical
hints”(
page 299).
iFor information on infants and children
traveling with you in the vehicle and
restraint systems for infants and
children, see “Children in the vehicle”
(page 69).
iThe1 indicator lamp remains lit if
the SmartKey in the starter switch is
turned to position2 and left there. The
indicator lamp will go out when you
start the engine.

Driving safety systems
In this section you will find information on
the following driving safety systems:
ABS (A
ntilock B

BAS (B
rake A
ssist S

ESP (E
lectronic S
tability P

4MATIC (Four Wheel Electronic
Traction System)
ABS
The Antilock Brake System (ABS) regulates
the brake pressure so that the wheels do
not lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The- indicator lamp in the instrument
cluster (
page 24) comes on when you
switch on the ignition. It goes out when the
engine is running.
iIn winter operation, the maximum
effectiveness of the ABS, ESP, and
4MATIC (if so equipped) is only
achieved with winter tires (M + S tires),
or snow chains as required.
Warning!
G
The following factors increase the risk of
accidents:
Excessive speed, especially in turns
Wet and slippery road surfaces
Following another vehicle too closely
The ABS, BAS, ESP, and 4MATIC (if so
equipped) cannot reduce this risk.
Always adjust your driving style to the
prevailing road and weather conditions.
Warning!
G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.
