Fastening seat belts
Observeth esafet ynote son th eseat belt
(Ypage 42 )and the notes on correct use of seat
belts (Ypage 43).
Basic illustration
XAdjust the seat (Ypage 95).
The seat backrest must be in an almost
upright position.
XPull the seat belt smoothly out of seat belt
guide =and engage belt tongue ;into belt
buckle :.
The seat belt on the driver’s seat and the
front-passenger seat may be tightened auto-
matically, see "Belt adjustment"
(
Ypage 44).
XIf necessary, pull up on the shoulder section
of the seat belt to tighten the belt across your
body.
In order to attach the child restraint system
securely in the vehicle, the seat belt on the front-
passenger seat is equipped with a special seat
belt retractor. Further information on the "Spe-
cial seat belt retractor" (
Ypage 57).
Releasing seat belts
!Make sure that the seat belt is fully rolled up.
Otherwise, the seat belt or belt tongue will be
trapped in the door or in the seat mechanism.
This could damage the door, the door trim
panel and the seat belt. Damaged seat belts
can no longer fulfill their protective function
and must be replaced. Visit a qualified spe-
cialist workshop.
XPress the release button in the belt buckle,
hold the belt tongue firmly and guide the belt
back.
Seat belt adjustment
The belt adjustment is a convenience function
integrated into PRE-SAFE®. With this function,
the driver's and front-passenger seat belts are
adjusted to the upper body of the vehicle occu-
pant.
The seat belt strap will slightly tighten if:
Rthe belt tongue is inserted into the buckle and
Rthe ignition is switched on
The seat belt adjustment will apply a certain
tightening force if any slack is detected between
the vehicle occupant and the seat belt. Do not
grab hold of the seat belt.
The belt adjustment can be switched on and off
using the on-board computer (
Ypage 197).
Belt warning for the driver and front
passenger
The 7 seat belt warning lamp in the instru-
ment cluster is a reminder that all vehicle occu-
pants must wear their seat belts. It may light up
continuously or flash. In addition, there may be
a warning tone.
Regardless of whether the driver's seat belt has
already been fastened, the 7seat belt warn-
ing lamp lights up for six seconds each time the
engine is started. If the doors are closed and the driver's or front-passenger seat belt has not
been fastened, the 7seat belt warning lamp
lights up again after the six seconds. As soon as
the driver's and front-passenger seat belts are
fastened or a front door is opened again, the
7 seat belt warning lamp goes out.
If the driver's seat belt is not fastened after the
engine is started, an additional warning tone will
sound. The warning tone switches off after six
seconds or once the driver's seat belt is fas-
tened.
If the vehicle's speed exceeds 15 mph
(25 km/h) once and the driver's and front-
passenger seat belts are not fastened, a warning
tone sounds. A warning tone also sounds with
increasing intensity for 60 seconds or until the
driver or front passenger have fastened their
seat belts.

XMake sure there is nothing between the seat cushion and the child
seat.
XMake sure that the entire base of the child restraint system rests on
the seat cushion of the front-passenger seat. The backrest of the
forward-facing child restraint system must lie as flat as possible
against the backrest of the front-passenger seat. If necessary,
adjust the position of the front-passenger seat.
XMake sure that the seat cushion length is fully retracted.
XWhen installing the child restraint system, make sure that the seat
belt is tight. Do not pull the seat belt tight using the front-passenger seat adjustment. This could result in the seat belt and the child
restraint system being pulled too tightly.
XCheck for correct installation of the child restraint system.
Make sure that the head restraint does not apply a load to the child
restraint system. If necessary, adjust the head restraint accord-
ingly.
XMake sure that no objects are applying additional weight onto the
seat.
XIf the PASSENGER AIR BAG OFF indicator lamp remains off and/or
the PASSENGER AIR BAG ON indicator lamp lights up, do not install a child restraint system on the front-passenger seat.
XHave OCS checked as soon as possible at an authorized Mercedes-Benz Center.
Roll bar
GDANGER
If the roll bar has developed a malfunction, it
may not function, e.g. in the event of an acci- dent. The roll bars may then not protect the
vehicle occupants as intended. This poses an
increased risk of injury or even fatal injury.
Have roll bars checked immediately at a quali-
fied specialist workshop.
GWARNING
If you place objects or clothing on the roll bar
covers, these could impair roll bar extension.
The roll bars may then not protect the vehicle occupants as intended. In addition, objects
could endanger the vehicle occupants when
the roll bar is extending. This poses an
increased risk of injury or even fatal injury.
Ensure that the movement area of the roll bar
covers is kept clear. Always stow all objects in
the vehicle correctly.

GWARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat.
GWARNING
If the driver's seat is not engaged, it could
move forwards as far as the next catch during movement such as braking or abrupt changes
of direction. As a result, you would be pushed
against your seat belt by the unsecured driv-
er's seat.
This could cause you to lose control of the
vehicle. The seat belt cannot protect as inten-
ded and could result in additional injury.
There is a risk of an accident and injury.
Before every journey, make sure that the driv-
er's seat is fully engaged.
Observe the safety notes on "Air bags"
(
Ypage 45) and "Children in the vehicle"
(Ypage 56).
GWARNING
If you adjust the seat height carelessly, you or
other vehicle occupants could be trapped and
thereby injured. Children in particular could
accidentally press the electrical seat adjust-
ment buttons and 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 adjustment sys-
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,
steering wheel or mirrors
Rfasten the seat belt
There is a risk 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 prevent damage to the seats and the seat
heating, observe the following notes:
RDo not spill liquids onto the seats. Dry the
seats as soon as possible if liquid does get
spilled on the seats.
RIf the seat covers are damp or wet, do not
switch on the seat heating. Also, do not use
the seat heating 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 pointed objects on the seat
cushions such as knives, nails or tools.
Where possible, use the seats only for car-
rying passengers.
RWhen operating the seat heating, do not
cover the seats with insulating materials,
e.g. blankets, coats, bags, protective cov-
ers, child seats or booster seats.
RWhen the seat heating is switched on, the
seat surface can be damaged as a result of
objects being placed on the seats; for
example, seat cushions, child seats and
protective covers not approved by
Mercedes-Benz.
!Make sure that there are no objects in the
footwell under or behind the seats when mov-
ing the seats back. There is a risk that the
seats and/or the objects could be damaged.
