ed in the vehicle, or with access to an un-
locked vehicle. Children could release the
parking brake, which could result in an acci-
dent and/or serious injury.

47
Getting started
Driving
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.
For more information on driving, see “Driv-
ing instructions” (
page 223).
iYou can open a locked door from the
inside. Open doors only when condi-
tions are safe to do so.
You can deactivate the automatic lock-
ing using the control system
(page 129).
!If you hear a warning signal when driv-
ing off, you have forgotten to release
the parking brake.
Release the parking brake.!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.
iVehicles with automatic transmission:
Wait for the gear selection process to
complete before setting the vehicle in
motion.Warning!
G
Vehicles with automatic transmission: It is
dangerous to shift the gear 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 acceler-
ate 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.
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
position R 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
speeds may shorten the service life of
the engine.

56 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


Lower anchors and tethers for children
(LATCH)
As independent systems, their protective
effects work in conjunction with each oth-
er. The
1 indicator lamp in the instrument
cluster (
page 22) comes on:


for about four seconds when you turn
the SmartKey in the starter switch to
position 1.


for about four seconds when you start
the engine by turning the SmartKey. The
1 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 de-
tected if the 1 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”
section (
page 262).
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 65).
iThe 1 indicator lamp remains lit if
the SmartKey is turned to position 2
and left there. The indicator lamp will
go out when you start the engine.

62 Safety and SecurityOccupant safetyThe front passenger side impact airbag will
only deploy if the system senses that the
front passenger seat is occupied.1 Window curtain airbag
2 Side impact airbagsSeat 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
started, 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.
For more information on seat belts see
“Fastening the seat belt” (
page 41).
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 65).
Warning!
G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained, even those sitting in the
rear and pregnant women.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your
risk of injuries and their likely severity in an
accident. You and your passengers should
always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
In the same crash, the possibility of injury or
death is lessened if you are properly wearing
your seat belt. Airbags can only protect as
they are designed if the occupants are prop-
erly wearing their seat belts.

 Driving safety systems
In this section you will find informations on
the following driving safety systems:

ABS (A

BAS (B

ESP (E

tability P

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 - indicator lamp in the instrument
cluster (
page 22) comes on when you
turn the SmartKey in the starter switch to
position 2. It goes out when the engine is
running. Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode.

Keep firm and steady pressure on the
brake pedal while experiencing the pul-
sation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to
steer the vehicle.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions and
functions as a reminder to take extra care
while driving.
iIn winter operation, the maximum ef-
fectiveness of the ABS, 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, 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.
