WARNING
Do not place electronic devices on the front-
passenger seat, e.g.:
R laptops, whe nswitched on
R mobile phones
R cards with transponders, e.g .ski passes or
access cards
Signals from electronic equipment can cause
interference in the sensor system of the air
bag deactivatio nsystem. This can lead to a
system malfunction .This may cause the
4 PASSENGER AIR BAG OFF indicator
lamp to light up even if no child seat with a
transponder for an air bag deactivation
system is installed. The front-passenger air
bag would not then deploy during an accident.
It is also possible that the 6SRS warning
lamp lights up and/or the 4PASSENGER
AIR BAG OFF indicator lamp does not light up
briefly when you turn the key in the ignition
lock to position 2. The sensor system of the air bag deactivation
system on the front-passenger seat detects
whether a special Mercedes-Ben
zchild seat
has been installed there. To support
detection by the sensor system, the
Mercedes-Benzc hild seat is equipped with
transponders for the air bag deactivation
system. In this case, the 45:indicator lamp lights up. The front-passenger
air bag is deactivated.
i
If the front-passenger air bag is
deactivated by the air bag deactivation
system, the following remain enabled on
the front-passenger side:
R the side impact air bag
R the window curtain air bag
R the Emergency Tensioning Device
LATCH-type (ISOFIX) child seat anchors
in the rear G

must travel in seats using normal seat belts.
Position the shoulder belt across the chest
and shoulder, not face or neck.
Ab ooster seat may be necessary to achieve
proper seat belt positioning for children over
41 lb (18 kg) until they reach a height where
a lap/shoulder belt fits properly without a
booster.
Install the child restraint system in
accordance with the manufacturer's
instructions.
Attach the child restraint system to both
securing rings.
An incorrectly installed child restraint system
could come loose during an accident and
seriously or even fatally injure the child.
Child restraint systems or child seat securing
rings that are malfunctioning or damaged as
the result of a collision must be replaced.
! When installing the child restraint system,
make sure that the seat belt for the middle
seat does not get trapped. The seat belt
could otherwise be damaged. Children in the vehicle

Important safety notes
G
WARNING
When leaving the vehicle, always remove the
SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system, and do not give them access
to an unlocked vehicle. Achild's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. They could:
R injure themselves on vehicle parts
R be seriously or fatally injured by extreme
heat or cold
R injure themselves or have an accident with
vehicle equipment that may still be in
operation even after the SmartKey has
been removed from the ignition, such as the
seat adjustment, steering wheel
adjustment or memory function.
If children open a door, they could cause
severe or even fatal injury to other persons; if
they get out of the vehicle, they could injure
themselves when doing so or be seriously or
even fatally injured by any passing traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very hot, and a child could be burned on these
parts.
G
WARNING
Do not attach any heavy or large key rings to
the key that is inserted in the ignition. If a key
ring is too heavy or too large, the weight acting
on the key could cause it to turn in the ignition
lock or catch on the steering wheel. This could
cause the engine to be switched off suddenly.
You could lose control of the vehicle and
cause an accident.
Keep the SmartKey away from strong
magnetic fields. Otherwise, the remote
control function could be affected.
Do not keep the SmartKey:
R with electronic devices, e.g. a mobile
phone or another SmartKey
R with metallic objects, e.g. coins or metal
foil
R inside metallic objects, e.g. a metal case SmartKey functions
