We recommend using Genuine
Mercedes-Benz parts as well as conversion
parts and accessories explicitly approved
by us for your vehicle model.
We have tested these parts to determine
their reliability, safety and special suitabili-
ty for Mercedes-Benz vehicles.We are unable to make an assessment for
other products and therefore cannot be
held responsible for them, even if in indi-
vidual cases an official approval or authori-
zation by governmental or other agencies
should exist. Use of such parts and acces-
sories could adversely affect the safety,
performance or reliability of your vehicle.
Please do not use them.Genuine Mercedes-Benz parts as well as
conversion parts and accessories
approved by us are available at your
authorized Mercedes-Benz Center where
you will receive comprehensive informa-
tion, also on permissible technical modifi-

74 Safety and SecurityOccupant safetyAutomatic 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.
Active head restraints
The active head restraints are intended to
offer the driver and front passenger in-
creased protection from head and neck
injury. In the event of a rear-end collision,
the active head restraints on the driver’s
and front passenger’s seats are designed
to move forward in the direction of travel,
providing the head with increased support
earlier on in the collision sequence. The ac-
tive head restraints move forward whether
the seat is occupied or not.
For information on resetting the activated
active head restraints, see “Resetting acti-
vated head restraints” (
page 406).You cannot remove the active head
restraints on the driver’s and passenger’s
seats.
For removal of the active head restraints
we recommend that you contact an
authorized 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 air bag on the passenger side
and, with the seat belt fastened to se-
cure the object, the ETD to deploy in a
crash which exceeds the system’s de-
ployment threshold.
Warning!
G
Do not attach any objects (e.g. hangers) to
the head restraint posts. Otherwise, the ac-
tive head restraints may not be able to func-
tion properly or offer the intended degree of
protection in the event of an accident.
Warning!
G
Only use seat or head restraint covers which
have been tested and approved by
Mercedes-Benz for your vehicle model.
Using other seat or head restraint covers
may interfere with or prevent the activation
of active head restraint. Contact your autho-
rized Mercedes-Benz Center for availability.
90 Safety and SecurityDriving safety systems
The electro-hydraulic brake system is auto-
matically activated when you
unlock the vehicle with the SmartKey
or the KEYLESS-GO*
open the driver’s or passenger door
turn the SmartKey in the starter switch
to position1
in vehicles with KEYLESS-GO*, press
the start/stop button on the gear
selector lever once
depress the brake pedal
release the parking brake
Warning!
G
The electro-hydraulic brake system requires
electrical power to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. In such a case, the
red brake warning lamp (
page 354) and
warning messages in the instrument cluster
(
page 363) come on while driving. To
brake, the driver must then apply signifi-
cantly greater brake pedal pressure and
depress the pedal much further to obtain
the expected braking effect. If necessary,
apply full pressure to the brake pedal.
Brakes may only be applied to the front
wheels. Stopping distance is increased!
If there is a malfunction in the
electro-hydraulic brake system, we recom-
mend that the vehicle be transported with
all wheels off the ground using flatbed or ap-
propriate wheel lift/dolly equipment.
A tow bar must be used if circumstances do
not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on
the ground is only permissible for distances
up to 30 miles (50 km) and at a speed not to
exceed 30 mph (50 km/h). For more infor-
mation, refer to “Towing the vehicle”
(page 437).

Warning!
G
A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions per-
mit it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.

you give more gas. The engine then
operates at lower rpms and the
wheels are less likely to spin.

Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.
iWhen you brake or stop, the transmis-
sion shifts down to a gear from which
you can easily accelerate or take off.
