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

Important safety notes G
WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you
could be trapped by the wiper arm. There is
a risk of injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! Never open the hood/tailgate or rear
doors if a windshield wiper arm has been
folded away from the windshield/rear win-
dow.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield/rear
window.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield/rear
window, the windshield/rear window may
be damaged by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
! Only hold the wiper blade by the wiper
arm. You could otherwise damage the wiper
rubber.
Wiper blades are wear parts. The windshield
will no longer be wiped properly if the wiper
blades are worn. This may prevent you from
observing the traffic conditions.
Please observe the service indicator after
changing the wiper blades of the windshield
wiper.
Service indicator Replacement wiper blades for the windshield
wiper have a service indicator on the tip of the
wiper blade.
Depending on the amount of use, the service
indicator will change color from black to yel-
low.110
