possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions rel-
evant to safety.

Important safety notes G
WARNING
Children could become trapped if they
adjust the seats, particularly when unatten-
ded. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle.
Never leave children unsupervised in the
vehicle. G
WARNING
You could lose control of your vehicle if you
do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint,
steering wheel and mirror and fasten your
seat belt before starting the engine. G
WARNING
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.
When adjusting a seat, make sure that no
one has any body parts in the sweep of the
seat. G
WARNING
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 a risk of an accident.
Always make sure that the driver's seat is
engaged before starting the vehicle. G
WARNING
The front-air bags for could also injure the
vehicle occupants in the front If the front
seats are positioned too close to the dash-
board or steering wheel. This poses an
increased risk of injury or even fatal injury.
Always adjust the front seats so that they
are as far from the front air bags as possi-
ble. Also observe the notes on the correct
adjustment of the seats. G
WARNING
The seat belt does not offer the intended
level of protection if you have not moved the
backrest to an almost vertical position.
When braking or in the event of an accident,
you could slide underneath the seat belt and
sustain abdomen or neck injuries, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the back-
rest is in an almost vertical position and that
the shoulder section of your seat belt is
routed across the center of your shoulder. G
WARNING
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. Seats

!
To prevent damage to the seats and the
seat heating, observe the following notes:
R Do not spill liquids onto the seats. Dry the
seats as soon as possible if liquid does
get spilled on the seats.
R If 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.
R Clean the seat covers as recommended;
see the "Interior care" section.
R Do 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 carrying passengers.
R When 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.
R When 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.
Your seat must be adjusted in such a way that
you can wear the seat belt correctly.
Observe the following points:
R Position the backrest in an almost vertical
position so that you are sitting virtually
upright. Do not drive with the backrest
reclined too far back.
R Your arms should be slightly bent when you
are holding the steering wheel.
R Avoid seat positions that prevent the seat
belt from being correctly routed. The shoul-
der section of the belt must be routed over
the middle of your shoulder and be pulled
tight against your upper body. The lap belt
must always pass across your lap as low
down as possible, i.e. over your hip joints.
R Adjust the head restraint so that it supports
the back of the head at eye level.
R The distance from the pedals should be
such that you can depress them fully.

specialist workshop without the risk of dam-
age. The tool is available as a Mercedes-
Benz accessory.

G
WARNING
Repeatedly switching on the seat heating
can cause the seat cushion and backrest
pads to become very hot. The health of per-
sons with limited temperature sensitivity or
a limited ability to react to high tempera-
tures may be affected or they may even suf-
fer burn-like injuries. There is a risk of injury.
Therefore, do not switch the seat heating on
repeatedly.
! When you leave your seat, do not place
anything on the seat and switch off the seat
heating. Do not switch the seat heating on
when the seat is not occupied, e.g. when
driving without a front passenger. The seat
heating may otherwise overheat, causing
damage to the seat. The three red indicator lamps in the
Í but-
ton show the activated heating level 1 to 3.
The seat heating automatically switches down
from level 3 to level 2 after approximately
seven minutes.
The system automatically switches down from
level 2 to level 1 after approximately ten
minutes.
At level 1 the seat heating switches off auto-
matically after approximately
20 minutes.
X Make sure that the key is in position 1 or 2
in the ignition lock.
X To switch on: press the Í button
repeatedly until the desired heating level
has been set.
X To switch off: press the Í button
repeatedly until all indicator lamps go out.
If the on-board voltage is too low, the seat
heating will either switch itself off prematurely
or not come on at all. In this case, too many
electrical consumers are switched on or the
battery charge is not sufficient. The seat heat-
ing will automatically switch back to the cur-
rent heating level when enough on-board volt-
age is available again. Steering wheel
