Carefully depress the accelerator
pedal.
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.
Warning!
G
When leaving the vehicle, always remove the
key from the steering lock and lock the vehi-
cle. Do not leave children unattended in the
vehicle, or with access to an unlocked vehi-
cle. Children could release the parking
brake, which could result in an accident
and/or serious injury.
iYou can open a locked door from the
inside. Open door only when conditions
are safe to do so.
!If you hear a warning signal when driv-
ing off, you have forgotten to release
the parking brake.

Warning!
G
Vehicles with automatic transmission: It is
dangerous to shift the selector lever out of
P
or
N 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 some-
thing. Only shift into gear when the engine is
idling normally and when your right foot is
firmly on the brake pedal.!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.
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.

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
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 ve-
hicle.
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.


Pull up the brake lever firmly.


Move the selector lever to position
P
(manual transmission: first or reverse
gear).


Slowly release brake pedal.


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

G
When leaving the vehicle, always remove the
key from the steering lock and lock the vehi-
cle. Do not leave children unattended in the
vehicle, or with access to an unlocked vehi-
cle. Children could release the parking
brake and/or move the gear selector lever
from positionP, either of which could result
in an accident and/or serious injury.
Warning!
G
Getting out of your vehicle with the selector
lever not fully engaged in positionP is dan-
gerous. Also, when parked on an incline,
positionP alone may not prevent your vehi-
cle from moving, possibly hitting people or
objects.
Always set the parking brake in addition to
shifting to positionP (manual transmission:
first or reverse gear).
When parked on an incline, turn front wheel
towards the road curb.
iAlways set the parking brake in addi-
tion to shifting to positionP (manual
transmission: first or reverse gear).
On steep slopes, turn the front wheels
towards the road curb.

52 Safety and SecurityOccupant safety
Occupant 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


Airbags


Child seats


Child seat recognition
As independent systems their protective
effects work in conjunction with each oth-
er.The1indicator lamp in the instrument
cluster lights up for about four seconds
when you turn the key in the steering lock
to position1 or2. It goes out when you
start the engine. This shows that the re-
straint systems are operational.
If the lamp does not come on at all or if it
fails to extinguish after approximately four
seconds or if it comes on thereafter, a mal-
function in the system has been detected.
More information can be found in the
“Practical hints” section (
page 203).
iFor information on infants and children
traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
(page 60).
Warning!
G
In the event that the SRS malfunction indica-
tor lamp lights up during driving or does not
come on at all, the SRS may not be opera-
tional. For your safety, we strongly recom-
mend that you visit an authorized
Mercedes-Benz Center immediately to have
the system checked; otherwise the SRS may
not be activated when needed in an acci-
dent, which could result in serious or fatal
injury, or it might deploy unexpectedly and
unnecessarily which could also result in inju-
ry.
Improper work on the restraint systems, in-
cluding incorrect installation and removal,
can lead to possible injury through an unin-
tended activation of the SRS.
In addition, through improper work there is
a risk of rendering the SRS inoperative or
causing unintended airbag deployment.
Work on the SRS must therefore only be per-
formed by qualified technicians. Contact
your authorized Mercedes-Benz Center.

57 Safety and Security
Occupant safety
Side impact airbags
The side impact airbags are deployed:

on the impacted side of the vehicle


in impacts exceeding a preset deploy-
ment threshold


independently of the front airbags
The side impact airbags will not deploy in
impacts which do not exceed the system’s
deployment threshold.
The passenger side impact airbag will only
be deployed if the system senses that the
passenger seat is occupied.
Seat belts
When the engine is started, the seat belt
non-usage warning lamp < illuminates
to remind you and your passengers to fas-
ten your seat belts. If the driver's seat belt
is not fastened before the engine is start-
ed, the seat belt non-usage warning lamp
< illuminates and a warning chime
sounds for approximately six seconds
when the engine is started.
The use of seat belts and infant and child
restraint systems is required by law in
most states and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts fas-
tened whenever the vehicle is in motion.
Information on fastening seat belts is
found in the “Getting started” section
(page 37).
!Do not place objects heavier than
20 lbs (9 kg) on the passenger seat.
This could cause the front or side im-
pact airbag on the passenger side to
deploy in a crash which exceeds the
system’s deployment threshold.
iFor information on infants and children
traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
(page 60).

66 Safety and SecurityDriving safety systems
Driving safety systemsIn this section you will find information on
the following driving safety systems:

ABS (A
ntilock B
rake S
ystem)


BAS (B
rake A
ssist S
ystem)


ESP (E
lectronic S
tability P
rogram)
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 re-
spond even with light brake pressure.
The - malfunction indicator lamp in the
instrument cluster (
page 20) lights up
when you turn the key in the steering lock
to position2. It goes out when the engine
is running.
iIn winter operation, the maximum ef-
fectiveness of the ABS and ESP is only
achieved with winter tires (M + S tires),
or snow chains as required.
Warning!
G
The following factors increase the risk of ac-
cidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
The ABS, BAS and ESP cannot reduce this
risk.
Always adjust your driving style to the pre-
vailing 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.
