Press the vertical switch forward or 
backward in direction of arrow3 until 
your arms are slightly angled when 
holding the steering wheel.
Seat cushion tilt
Press the horizontal switch up or down 
in direction of arrow4 until your up-

Head restraint
Adjust the height of head restraints 
manually by pulling them upwards or 
pushing them downwards.
Warning!
G
For your protection, drive only with properly 
positioned head restraints.
Adjust head restraint so that the head re-
straint supports the back of the head at eye 
level. This will reduce the potential for injury 
to the head and neck in the event of an ac-
cident or similar situation.
Do not drive the vehicle without the seat 
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
iAdjust the head restraint in such a way 
that it is as close to the head as 
possible.

DrivingWarning!
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.!If you hear a warning signal and the 
message 
Release parking brake
 ap-
pears in the multifunction display when 
driving off, you have forgotten to re-
lease the parking brake.
!Simultaneously depressing the acceler-
ator pedal and the brake pedal reduces 
engine performance and causes pre-
mature brake and drivetrain wear.iOnce the vehicle is in motion, the auto-
matic central locking system engages 
and the locking knobs drop down.

Warning!
G
Getting out of your vehicle with the gear se-
lector lever* not fully engaged in positionP 
(manual transmission: first or reverse gear) 
is dangerous. Also, when parked on an in-
cline, positionP (manual transmission: first 
or reverse gear) alone may not prevent your 
vehicle 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 the front 
wheels towards the road curb.
Warning!
G
When leaving the vehicle, always remove the 
SmartKey from the starter switch, take it 
with you, and lock the vehicle. Do not leave 
children unattended in the vehicle, or with 
access to an unlocked vehicle. Children 
could release the parking brake and/or 
move the gear selector lever* from 
positionP (manual transmission: into 
Neutral), either of which could result in an 
accident and/or serious injury.

Manual transmission: Move the gear-
shift lever into first or reverse gear.
Automatic transmission*: Place the 
gear selector lever in positionP.
Turn the SmartKey in the starter switch 
to position0 and remove the SmartKey 
from the starter switch.
The immobilizer is activated.
Press the seat belt release button 
(page 49).
Guide the latch plate to allow the re-
tractor to completely rewind the seat 
belt.
iAlways set the parking brake in addi-
tion to shifting into first or reverse gear 
(automatic transmission*: gear selec-
tor lever in positionP).
On slopes, turn the front wheels to-
wards the road curb.
iVehicles with automatic transmission*: 
The SmartKey can only be removed 
from the starter switch with the gear 
selector lever in positionP.
!Make sure the seat belt retracts fully so 
that the seat belt and/or latch plate 
cannot get caught or pinched in the 
door or in the seat mechanism. This 
can damage the seat belt and impair 
the effectiveness of the seat belt, 
and/or cause damage to the door 
and/or door trim panel. Such damage 
is not covered by the Mercedes-Benz 
Limited Warranty.
Damaged seat belts must be replaced. 
Contact an authorized Mercedes-Benz 
Center.iWith the SmartKey removed from the

Locking
Exit the vehicle and close all doors.
Press the lock button‹ on the 
SmartKey (
page 34).
With the trunk and all doors closed, all 
turn signal lamps flash three times. The 
locking knobs on the doors move 
down.
The anti-theft alarm system is armed 
now (
page 87).
For more information, see “Locking and 
unlocking” (page 92).
iOpening a door causes the windows on 
that side of the car to open slightly. 
They will return to the up position when 
the door is closed.!The side windows will not open or close 
if the battery is discharged or the win-
dows are covered with ice. As a result, 
you may no longer be able to properly 
close the door. Do not attempt to force 
the door shut. Doing so may damage 
the door or the side window. Correct 
the condition that prevents the 
windows from operating before 
attempting to close the door.
Warning!
G
To prevent possible personal injury, always 
keep hands and fingers away from the door 
openings when closing the doors. Be espe-
cially careful when small children are 
around.
Before closing doors, make sure there is no 
possibility of someone getting caught in a 
door during closing.Warning!
G
When leaving the vehicle, always remove the 
SmartKey from the starter switch, take it 
with you, and lock the vehicle. Do not leave 
children unattended in the vehicle, or with 
access to an unlocked vehicle. Unsuper-
vised use of vehicle equipment may cause 
an accident and/or serious personal injury.
iWithout the antenna on the left rear 
side of the vehicle installed, the 
SmartKey signaling range is consider-
ably reduced. Hold the SmartKey in 
close proximity towards the antenna 
base when locking or unlocking the 
vehicle.

82 Safety and SecurityDriving safety systemsIn this section you will find information on 
the following driving safety systems:
ABS (A
ntilock B
rake S
ystem)
BAS (B

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 
approximately 5 mph (8 km/h) indepen-
dent of road surface conditions.
On slippery road surfaces, the ABS will 
respond even to light brake pressure.
The -indicator lamp in the speedome-
ter dial (
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, the BAS, and 
the ESP
® is only achieved with winter 
tires (
page 348), 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, 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.
