Never modify an air bag cover or affix objects
to it.
GWARNING
Sensors to control the air bags are located in
the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to the
function of the sensors being impaired. The air
bags might therefore not function properly
anymore. Consequently, the air bags cannot
protect vehicle occupants as they are
designed to do. There is an increased risk of
injury.
Never modify the doors or parts of the doors.

eling carried out at aqualifieds pecialist work-
shop.
Front air bags
!Do not place heavy objects on the front-
passenger seat. This could cause the system
to identify the seat as being occupied .Inthe
event of an accident, the restraint systems on
the front-passenger side may be triggered
and have to be replaced.
Driver's air bag :deploys in front of the steer-
ing wheel.F ront-passenger front air bag ;
deploys in front of and above the glove box.
When deployed, the front air bags offer addi-
tional head and thorax protection for the occu-
pants in the driver's and front-passenger seats.
The PASSENGER AIR BAG OFF and PASSENGER

the status of the front-passenger air bag

Kne ebags
Driver's knee bag :deploys under the steering
column and front-passenger knee bag ;under

knee bags are triggered together with the front
air bags.
The driver's and front-passenger knee bags
offer additional thigh, knee and lowerl eg pro-
tection.
Side impact air bags
GWARNING
Unsuitabl eseat covers can obstruct or pre-
vent deployment of the air bags integrated
into the seats. Consequently, the air bags
cannot protect vehicle occupants as they are designed to do. In addition, the operatio nof
the occupant classification system (OCS)
could be adversel yaffected. This poses an
increased risk of injury or even fatal injury.
You shoul donly use seat covers that have
been approve dfor the respective seat by
Mercedes-Benz.

Rclosing the sid ewindows.
Rvehicles with amemory function: setting a

!Make sure that there are no objects in the

good time, and for staying in lane. Always adapt
your driving style to suit the prevailing road and
weather conditions and maintainasafe distance
from the vehicle in front.D rive carefully.
The driving safety systems described only work
as effectively as possible when there is ade-
quate contact between the tires and the road
surface. Pay particular attention to the informa-
tion regarding tires, recommended minimum
tire tread depths etc. in the "Wheels and tires"
section (
Ypage 255).
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains.
Only in this way will the driving safety systems
described in this section work as effectively as
possible.
ABS (Anti-lock Braking System)
General information
ABS regulates brake pressure in such away that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when
braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from aspeed of about 5mph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, even when you
only brake gently.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 54).
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally,f urther driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at aqualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (
Ypage 204) and dis- play messages which may be shown in the
instrument cluster (
Ypage 179).
Braking
XIf ABS intervenes:
continue to depress the
brake pedal vigorously until the braking sit-
uation is over.
XTo make afull brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions, and functions as a reminder to take extr acare while driving.
BAS (Brake Assist System)
General information
BAS operates in emergencyb raking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 54).
GWARNING
If BAS is malfunctioning, the braking distance
in an emergencyb raking situation is
increased. There is arisk of an accident.
In an emergencyb raking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking
XKeep the brake pedal firmly depressed until
the emergencyb raking situation is over.
ABS prevent sthe wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.

GWARNING
When you adjust aseat, you or other vehicle
occupantsc ould become trapped, e.g. on the
seat guide rail. There is arisk of injury.
Make sure when adjusting aseat that no one
has any body parts in the sweep of the seat.
Observe the safety notes on "Air bags"
(
Ypage 42) and "Children in the vehicle"
(Ypage 51).
GWARNING
If the driver's seat is not engaged, it could
move unexpectedly while the vehicle is in
motion .This could cause you to lose control of
the vehicle. There is arisk of an accident.
Always make sure that the driver's seat is
engaged before starting the vehicle.
GWARNING
If you adjust the seat height carelessly, you or
other vehicle occupantsc ould be trapped and
thereby injured. Children in particular could
accidentally press the electrical seat adjust-
ment button sand become trapped. There is a
risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under the
lever assembly of the seat adjustmen tsys-
tem.
GWARNING
If the head restraints are not installed or not
adjusted correctly, they cannot provide pro-
tection as intended. There is an increased risk
of injury in the head and neck area, e.g. in the event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level.
GWARNING
You could lose control of your vehicle if you do the following while driving:
Radjust the driver's seat, head restraint,
steerin gwheel or mirrors
Rfasten the seat belt
There is arisk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine.
!To avoid damage to the seats and the seat
heating, observe the following information:
Rkeep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
Rif the seat covers are damp or wet, do not
switch on the seat heating. The seat heat-
ing should also not be used to dry the seats.
Rclean the seat covers as recommended;
see the "Interior care" section.
Rdo not transport heavy loads on the seats.
Do not place sharp object sonthe seat
cushions, e.g. knives, nails or tools. The
seats should only be occupied by passen-
gers, if possible.
Rwhen the seat heating is in operation, do
not cover the seats with insulating materi-
als, e.g. blankets ,coats, bags, seat covers,
child seats or booster seats.
!Make sure that there are no object sinthe
footwell under or behind the seats when mov-
ing the seats back. There is arisk that the
seats and/or the object scould be damaged.
iThe head restraints are equipped with the
NECK-PRO system (Ypage 50). For this rea-
son, it is not possible to remove the head
restraints from the seats.
