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.
Using the fore-and-aft adjustment, adjust thehead restraint so that it is as close as possible toyour head.
GWARNING
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.
GWARNING
You could lose control of your vehicle if you do
the following while driving:
Radjust the driver's seat, head restraint,
steering wheel or mirrors
Rfasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt
before starting the engine.
GWARNING
If you adjust the seat height carelessly, you or
other vehicle occupants could be trapped and
thereby 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
The seat belt does not offer the intended level
of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal
injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
!To prevent damage to the seats and the seatheating, observe the following notes:
RDo not spill liquids onto the seats. Dry theseats as soon as possible if liquid does getspilled on the seats.
RIf the seat covers are damp or wet, do notswitch on the seat heating. Also, do not usethe seat heating to dry the seats.
RClean the seat covers as recommended;see keyword "Care".
RDo not transport heavy loads on the seats.Do not place pointed objects on the seatcushions such as knives, nails or tools.Where possible, use the seats only for car-rying passengers.
RWhen operating the seat heating, do notcover the seats with insulating materials,e.g. blankets, coats, bags, protective cov-ers, child seats or booster seats.
!Make sure that there are no objects in thefootwell under or behind the seats when mov-ing the seats back. There is a risk that theseats and/or the objects could be damaged.

Problems with the seat heating / seat ventilation
ProblemPossible causes/consequences andPPSolutions
The seat heating or seatventilation has switchedoff prematurely or can-not be switched on.
The on-board voltage is too low because too many electrical consum-ers are switched on.
XSwitch off electrical consumers that you do not need, such as therear window defroster or interior lighting.Once the battery is sufficiently charged, the seat heating or seatventilation can be switched back on manually.

Switching cooling with air dehumidification on/off
General notes
If you deactivate the "Cooling with air-dehumidification" function, the air inside the vehicle will notbe cooled. The air inside the vehicle will also not be dehumidified. The windows can fog up morequickly. Therefore, only deactivate the "Cooling with air-dehumidification" function briefly.
The "Cooling with air dehumidification" function is only available when the engine is running. The airinside the vehicle is cooled and dehumidified according to the temperature selected.
Condensation may drip from the underside of the vehicle when it is in cooling mode. This is normaland not a sign that there is a malfunction.

Problems with the rear window defroster
ProblemPossible causes/consequences andPPSolutions
The rear windowdefroster has deactiva-ted prematurely or can-not be activated.
The battery has not been sufficiently charged.
XSwitch off any consumers that are not required, e.g. reading lamps,interior lighting or the seat heating.When the battery is sufficiently charged, the rear window defrostercan be activated again.

General notes
You can also temporarily deactivate the flow offresh air manually if unpleasant odors are enter-ing the vehicle from outside. The air alreadyinside the vehicle will then be recirculated.
If you switch on air-recirculation mode, the win-dows can fog up more quickly, in particular atlow temperatures. Only use air-recirculationmode briefly to prevent the windows from fog-ging up.
Activating/deactivating
XTurn the SmartKey to positionHin the igni-tion lock (Ypage 131).
XTo activate:press therrocker switch upor down.The indicator lamp above therrockerswitch lights up.
Air-recirculation mode switches on automati-cally:
Rat high outside temperatures
Rat high levels of pollution (3-zone automaticclimate control only)
Rin a tunnel (vehicles with a navigation systemonly)
The indicator lamp above therrockerswitch is not lit when automatic air-recirculationmode is activated. Outside air is added afterabout 30 minutes.
XTo deactivate:press therrocker switchup or down.The indicator lamp above therrockerswitch goes out.
Air-recirculation mode deactivates automati-cally:
Rafter approximately five minutes at outsidetemperatures below approximately 41 ‡(5 †)
Rafter approximately five minutes if coolingwith air dehumidification is deactivated
Rafter approximately 30 minutes at outsidetemperatures above approximately 41 ‡(5 †) if the "Cooling with dehumidification"function is activated

General notes
The residual heat function is only available with3-zone automatic climate control.
Once the engine is switched off, it is possible tomake use of the residual heat of the engine tocontinue heating or ventilating the front com-partment of the vehicle for approximately30 minutes. The heating or ventilation timedepends on the interior temperature that hasbeen set.

Transfer case
This section is only valid for vehicles with 4-wheel drive (4MATIC). Power is always trans-mitted to both axles.
!Performance tests may only be carried outon a 2-axle dynamometer. The brake systemor transfer case could otherwise be damaged.Contact a qualified specialist workshop for aperformance test.
!Since ESP®engages automatically, the igni-tion must be switched off (the SmartKey orStart/Stop button must be in positionZorG) if
Rthe electrical parking brake is being testedusing a dynamometer
Rthe vehicle is being towed with only oneaxle raised (not permitted for vehicles with4MATIC)
Otherwise, the brake system can be dam-aged.
!Vehicles with 4MATIC must not be towedwith either the front or the rear axle raised, asdoing so will damage the transmission.
