Adjust seat to a comfortable seating
position that still allows you to reach

properly operate controls.
Warning!
G
Children 12 years old and under must never
ride in this vehicle, except in a
Mercedes-Benz authorized BabySmart
TM1
compatible child seat, which operates with
the BabySmart
TM system installed in the ve-
hicle to deactivate the passenger front air-
bag when it is properly installed. Otherwise
they will be struck by the airbag when it in-
flates in a crash. If this happens, serious or
fatal injury will result.
Infants and small children must be seated in
an appropriate infant or child restraint sys-
tem, which is properly secured with the ve-
hicle’s seat belt, fully in accordance with the
child seat manufacturer’s instructions.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.

!When moving the seats, make sure
there are no items in the footwell or be-
hind the seats. Otherwise you could
damage the seats.

tion together with the settings for the

rors.
61 Safety and Security
Occupant safety
Warning!
G
Should you choose to place a child 12 years
old or under in the passenger seat of your
vehicle, you must properly use a
BabySmart
TM child restraint which will turn
off the passenger front airbag (
page 70).
BabySmart
TM will not, however, turn off any
side impact airbag.
It should be noted, however, that there is a
possibility for a head-thorax airbag related
injury if occupants, especially children, are
not properly seated or restrained when next
to a head-thorax airbag which needs to de-
ploy rapidly in a side impact in order to do its
job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
head-thorax airbag inflates. This could
result in serious injuries or death should
the head-thorax airbag be activated.
(2) Always sit nearly upright, properly use
the seat belts and use an appropriately
sized infant or child restraint system for
all children 12 years old or under.
(3) Always wear seat belts properly.
If you believe that, even with the use of
these guidelines, it would be safer for your
passenger seat occupants to have the pas-
senger side head-thorax airbag deactivated,
then deactivation can be accomplished
upon your written election to do so at an au-
thorized Mercedes-Benz Center at an addi-
tional cost. Please contact your local
authorized Mercedes-Benz Center or call
our Customer Assistance Center at
1-800-FOR-MERCedes (1-800-367-6372)
for details.

Driving safety systems
For more information, see the
“Practical hints” section (
page 282).Switching off the ESP
To improve the vehicle's traction, turn off
the ESP in driving situations where it would
be advantageous to have the drive wheels
spin and thus cut into surfaces for better
grip such as:
starting out on slippery surfaces and in
deep snow in conjunction with snow
chains
in sand or gravelThe switch is located in the lower part of
the center console.
1ESP switch
Press ESP switch1 until the ABS/ESP
warning lamp v in the instrument
cluster comes on.
ESP is deactivated.
!Because of the ESP’s automatic opera-
tion, the engine must be shut off
(SmartKey in starter switch position 0
or 1 or KEYLESS-GO* start/stop but-
ton in position 0 or 1) when
the parking brake is being tested on
a brake test dynamometer
the vehicle is being towed with the
front/rear axle raised
Active braking action through the ESP
may otherwise seriously damage the
brake system.
The ESP will only function properly if
you use wheels of the recommended
tire size (
page 378).
Warning!
G
ESP should not be switched off during nor-
mal driving other than in the circumstances
described below. Disabling of the system
will reduce vehicle stability in standard driv-
ing maneuvers.!Turn on the ESP immediately if the
aforementioned circumstances do not
apply anymore.
iDistronic* cannot be activated when
the ESP has been deactivated.
80 Safety and SecurityDriving safety systemsIf one or more drive wheels are spinning,
the ABS/ESP warning lamp v in the in-
strument cluster flashes, regardless of the
speed.
Traction control brakes a spinning wheel
even when the ESP is deactivated.
The ESP always operates when you are
braking, even when it has been deactivat-
ed.Switching on the ESP
Press ESP switch1.
The ABS/ESP warning lamp v in
the instrument cluster goes out.
You are now again in normal driving
mode.
!Avoid spinning of a drive wheel for an
extended period with the ESP switched
off. This may cause serious damage to
the drivetrain which is not covered by
the Mercedes-Benz Limited Warranty.Warning!
G
When the ABS/ESP warning lamp
v
is
illuminated continuously, the ESP is
switched off.
Adapt your speed and driving to the prevail-
ing road conditions and to the non-operating
status of the ESP.

Open the respective door.
All the lamps in the instrument cluster
come on when the ignition is switched
on.
!Prior to operating the vehicle, the driv-
er should check and adjust the seat
height, seat position fore and aft, and
seat backrest angle if necessary, to en-
sure adequate control, reach and com-
fort. The head restraint should also be
adjusted for proper height. See also the
section on airbags (
page 59) for
proper seat positioning.
In addition, adjust the steering wheel to
ensure adequate control, reach, opera-
tion and comfort. Both the inside and
outside rear view mirrors should be ad-
justed for adequate rear vision.
Fasten seat belts. Infants and small
children should be seated in a properly
secured restraint system that complies
with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor Ve-
hicle Safety Standard 213.
Warning!

Do not activate the memory function while
driving. Activating the memory function
while driving could cause the driver to lose
control of the vehicle.

The rear window defroster uses a large
amount of power. To keep the battery
drain to a minimum, switch off the defrost-
er as soon as the rear window is clear. The
defroster is automatically deactivated af-
ter approximately 6 to 17 minutes of oper-
ation depending on the outside
temperature.

Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.!The rear window defroster cannot be
switched on when the retractable hard-
top is open. The indicator lamp will
start flashing if the hardtop is open.
Close the retractable hardtop.
The rear window defroster can again be
turned on.
!If the rear window defroster switches
off too soon and the indicator lamp
starts flashing, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-

responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster au-
tomatically turns itself back on.

Driving systems
Driving systems
The driving systems of your vehicle are de-
scribed on the following pages:
Cruise control and Distronic*, with
which the vehicle can maintain a preset
speed
ABC with vehicle level control systems,
with which you can change vehicle sus-
pension characteristics
Parktronic*, which assists the driver
during parking maneuvers
For information on the BAS, ABS, and ESP,
see “Driving safety systems” (
page 75).
Cruise control
The cruise control automatically maintains
the speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time. You can set or resume
cruise control at any speed over 20 mph
(30 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever found on the left-hand side of the
steering column (
page 20).
Warning!
G
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always re-
main responsible for the vehicle speed and
for safe brake operation.
Only use the cruise control if the road,
traffic, and weather conditions make it ad-
visable to travel at a steady speed.
The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.
The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.
Deactivate the cruise control when driv-
ing in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.
