Important safety notes
GWARNING
Children could become trapped if they adjust
the seats, particularly when unattended.
There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Neverleave children unsupervised in the 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.
Observe the safety notes on "Air bags" ( Y page 46) and "Children in the vehicle"
( Y page 57).
GWARNING
If the driver's seat is not engaged, it could

engaged before starting the vehicle.
GWARNING
If you adjust the seat height carelessly, you orother vehicle occupants could be trapped andthereby 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 head restraints are not installed and adjus-
ted correctly, they cannot provide protection
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

see the "Interior care" section.
R do not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions, e.g. knives, nails or tools.
The seats should only be occupied by
passengers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating mate- rials, e.g. blankets, coats, bags, seat cov-
ers, child seats or booster seats.
!Make sure that there are no objects in the
footwell under or behind the seats when
moving the seats back. There is a risk that
the seats and/or the objects could be dam-
aged.

ability to react to excessively high tempera-
tures may be affected or they may even suffer burn-like injuries. There is a risk of injury.
Therefore, do not switch the seat heating on
repeatedly.

Problems with the seat heating
The seat heating has switched off prema-
turely or cannot be switched on. The vehicle'selectrical system voltage is too low because
too many electrical consumers are switchedon.
X Switch off electrical consumers that you do
not need, such as the rear window
defroster or interior lighting.
X Once the battery is sufficiently charged,
switch on the seat heating again.
AIRSCARF
Activating/deactivating
GWARNING
When AIRSCARF is switched on, very hot air
can flow from the vents in the head restraints. This could result in burns in the immediate
vicinity of the air vents. There is a risk of injury.
Reduce the heater output before it becomes
too hot.
The AIRSCARF function warms the head and
neck area of vehicle occupants with warm air.
The warm air flows out of the holes in the head restraints.
The three red indicator lamps in the button
indicate the heating level you have selected. X
Make sure that the SmartKey is in position
2 in the ignition lock.
X To switch on: press button:.
Three red indicator lamps in the button light
up. The blower starts up after a preheating phase of seven seconds.
X Press button :repeatedly until the
desired heating level is set.
X To switch off: press button:repeatedly
until all the indicator lamps go out.
iThe blower continues running for seven
seconds to cool down the heating ele-
ments.
iIf the battery voltage is too low, AIRSCARF
may switch off.
Problems with AIRSCARF
AIRSCARF has switched off prematurely or
will not switch on. The vehicle's electrical sys-
tem voltage is too low because too many
electrical consumers are switched on.
X Switch off electrical consumers that you do
not need, such as the rear window
defroster or interior lighting.
X Switch on AIRSCARF again.
