Do not pass belts over sharp edges. They
could tear.
Do not allow the belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the belts.
Damaged seat belts or belts that were highly
stressed in an accident must be replaced.
Contact an authorized Mercedes-Benz Cen-
ter.
Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one win-
dow fully open.
44 Getting startedDrivingStarting with the SmartKey
Make sure the gear selector lever is set
to P.
Do not depress the accelerator.
Turn the SmartKey in the starter switch
to position3 and hold until the engine
starts (
page 31).
Depress the brake pedal.
The selector lever lock is released.
For information on turning off the engine
with the SmartKey, see “Turning off en-
gine” (
page 52).Starting with KEYLESS-GO*
You can start your vehicle without the
SmartKey in the starter switch using the
KEYLESS-GO start/stop button on the
gear selector lever.
The SmartKey with KEYLESS-GO must be
located in the vehicle.
1KEYLESS-GO start/stop button
Make sure the gear selector lever is set
toP.
Depress the brake pedal during the
starting procedure. Do not depress ac-
celerator.
The selector lever lock is released.
Press KEYLESS-GO start/stop
button1 once.
The engine starts automatically if the
SmartKey with KEYLESS-GO is in the
vehicle.
For information on turning off the engine
with KEYLESS-GO, see “Turning off with
KEYLESS-GO*” (
page 53).
iYou can also use the “touch-start”
function. Turn the SmartKey to
position3 and release it again immedi-
ately. The engine then starts automati-
cally.
46 Getting startedDrivingDriving
Depress the brake pedal.
Move selector lever to positionDorR.
Release the brake pedal.
Carefully depress the accelerator
pedal.
Once the vehicle is in motion, the automat-
ic central locking system engages and the
locking knobs drop down.After a cold start the automatic transmis-
sion engages at a higher revolution. This al-
lows the catalytic converter to reach its
operating temperature earlier.
More information on driving can be found
in the “Operation” section (
page 267).
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.
!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.
Warning!
G
It is dangerous to shift the gear selector le-
ver out ofP orN if the engine speed is high-
er than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could accel-
erate 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.!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.

Wiping will not occur with a door open.
!Do not leave windshield wipers in inter-
mittent setting when the vehicle is tak-
en to an automatic car wash or during
windshield cleaning. Wipers will oper-
ate in the presence of water sprayed on
the windshield, and wipers may be
damaged as a result.
The switch should not be left in inter-
mittent setting as the wipers will wipe
the windshield once every time the en-
gine is started. Dust that accumulates
on the windshield might scratch the
glass and / or damage the wiper blades
when wiping occurs on a dry wind-
shield.
65 Safety and Security
Occupant safety
In an impact, emergency tensioning devic-
es remove slack from the belts in such a
way that the seat belts fit more snugly
against the body. Belt force limiters reduce
the force exerted by the seat belts on oc-
cupants during a crash.Automatic comfort-fit feature seat belt
An automatic comfort-fit feature for front
seats reduces the retracting force of the
seat belts when they are in normal use.
Children in the vehicle
If an infant or child is traveling with you in
the vehicle:
Secure the child using an infant or child
restraint appropriate to the age and
size of the child and recommended for
use by Mercedes-Benz.
Ensure that the infant or child is prop-
erly secured all times while the vehicle
is in motion.
Infant and child restraint seats and infor-
mation on choosing an appropriate re-
straint system can be obtained from any
Mercedes-Benz Center.Infant and child restraint systems
Use only a BabySmart
TM1
compatible child
restraint for the front passenger seat in
this vehicle.
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
All lap-shoulder belts except the driver’s
seat belt have special seat belt retractors
for secure fastening of child restraints.
To fasten a child restraint, follow child re-
straint instructions for mounting. Then pull
the shoulder belt out completely and let it
retract. During seat belt retraction, a ratch-
eting sound can be heard to indicate that
the special seat belt retractor is activated.
The belt is now locked. Push down on child
restraint to take up any slack.
Warning!
G
An emergency tensioning device (ETD) that
was activated must be replaced.
When disposing of the emergency tension-
ing device, our safety instructions must be
followed. These are available at your autho-
rized Mercedes-Benz Center.!Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the front or side
impact airbag on the front passenger
side to deploy in a crash which exceeds
the system's deployment threshold.

SBC (S

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 re-
spond even with light brake pressure.
iIn winter operation, the maximum ef-
fectiveness of the ABS, the BAS, the
ESP, SBC and 4MATIC 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, SBC and 4MATIC 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.
76 Safety and SecurityDriving safety systemsBAS
The Brake Assist System (BAS) operates in
emergency situations. If you apply the
brakes very quickly, the BAS automatically
provides full brake boost, thereby poten-
tially reducing the braking distance. Apply
continuous full braking pressure until the
emergency braking situation is over. The
ABS will prevent the wheels from locking.
When you release the brake pedal, the
brakes function again as normal. The BAS
is then deactivated.
ESP
The Electronic Stability Program (ESP)
monitors the vehicle's traction (force of
adhesive friction between the tires and the
road surface) and handling.
The ESP recognizes when a wheel is spin-
ning or if the vehicle starts to skid. By ap-
plying brakes to the appropriate wheel and
by limiting engine output, the ESP works to
stabilize the vehicle. The ESP is especially
useful while driving off and on wet or slip-
pery road surfaces.
The ABS/ESP warning lamp v in the
instrument cluster flashes when the ESP is
engaged.
The ABS/ESP warning lamp v in the
instrument cluster comes on when you
turn the SmartKey in the starter switch to
position2 or press the KEYLESS-GO*
start/stop button twice. It goes out when
the engine is running.
Warning!
G
The BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking efficiency beyond that
afforded by the condition of the vehicle
brakes and tires or the traction. The BAS
cannot prevent accidents, including those
resulting from excessive speed in turns, fol-
lowing another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful
driver can prevent accidents. The capabili-
ties of a BAS equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.

“Practical hints” section (
page 311).
Warning!
G
Never switch off the ESP when you see the
ABS/ESP warning lamp v fl as h in g i n t he
instrument cluster. In this case proceed as
follows:
While driving off, apply as little throttle
as possible.
While driving, ease up on the accelera-
tor.
Adapt your speed and driving style to
the prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP cannot prevent accidents resulting
from excessive speed.
Warning!
G
The ESP cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded. The ESP
cannot prevent accidents, including those
resulting from excessive speed in turns, or
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of an ESP equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the us-
er’s safety or the safety of others.!The ESP will only function properly if
you use wheels of the recommended
tire size (
page 394).
!Vehicles without 4MATIC:
Because of the ESP’s automatic opera-
tion, the engine and ignition must be
shut off (SmartKey in starter switch
position0 or1 or KEYLESS-GO
start/stop button* in position0 or1)
when:
the parking brake is being tested on
a brake test dynamometer
the vehicle is being towed with the
front axle raised
Active braking action through the ESP
may otherwise seriously damage the
brake system.
For information on vehicles with
4MATIC, see “Four wheel electronic
traction system (4MATIC) with the
ESP” (
page 82).
