Wa r n i n g !
Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmart
TM compatible child seat,
which operates with the BabySmart
TM system
installed in the vehicle to deactivate the passenger-
side front airbag when it is properly installed.
Otherwise t hey will be stru ck by t he airbag wh en it
inflates in a crash. If this happens, serious or fatal
injury can result.
According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in the back
seats and be seated in an appropriate infant or
child restraint system, which is properly secured
with the vehicle’s seat belt, fully in accordance
with the child seat manufacturer’s instructions.A child’s risk of serious or fatal injuries is
significantly increased if the child restraints are
not properly secured in the vehicle and the child is
not properly secured in the child restraint.

The seat heaters can be switched on with the electronic
key in steering lock positions 1 or 2.Notes:
When in operation, the seat heater consumes a large
amount of electrical power. It is not advisable to use the
seat heater longer than necessary.
The seat heaters may automatically switch off if too
many power consumers are switched on at the same
time, or if the battery charge is low. When this occurs,
the indicator lamp in the switch will blink (both
indicator lamps blink during rapid seat heating mode).
The seat heaters will switch on again automatically as
soon as sufficient voltage is available.
If the blinking of the indicator lamps is distracting to
you, the seat heaters can be switched off.
