GWARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on
the seat guide rail. There is a risk of injury.
When adjusting a seat, make sure that no
one has any body parts in the sweep of the
seat.
!Make sure that there are no containers inthe cup holder and no objects in the foot-well or behind the seats when adjusting theseats. Otherwise, you could damage theseats and the objects.
You can move the seat forwards in order togain better access to the rear compartment,e.g. to reach the stowage compartment in therear passenger compartment .

Switching the seat heating on/off
Switching on/off
GWARNING
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 the seat heating is switched on, theseat surface can be damaged as a result ofobjects being placed on the seats, for exam-ple, seat cushions, child seats and protec-tive covers not approved by Mercedes-Benz.
Ensure that there are no objects on the seatsurface when the seat heating is switchedon.

AIRSCARF
Setting head level heating (AIRSCARF)
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 andneck area of vehicle occupants with warm air.The warm air flows out of the holes in the headrestraints.
The three red indicator lamps in the buttonindicate the heating level you have selected.
XEnsure that the SmartKey is in positionHin the ignition lock.
XTo switch on:press buttonC.Three red indicator lamps in the button lightup. The blower starts up after a preheatingphase of seven seconds.
XPress buttonCrepeatedly until the desiredheating level is set.
XTo switch off:press buttonCrepeatedlyuntil all the indicator lamps go out.

When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. This
also applies for the Digital Vehicle Key if the
"Digital Vehicle Key" function is activated via
Mercedes me connect.
The memory function can be activated at anytime, e.g. even when the SmartKey is not inthe ignition lock.
With the memory function, you can store up tothree different settings, e.g. for three differentpeople.
The following settings are stored as a singlememory preset:
RPosition of the seat, backrest and headrestraint
RDriver's side: steering wheel position
RDriver's side: position of the exterior mirrorson the driver's and front-passenger sides
XAdjust the seat electrically (Ypage 99).
XOn the driver's side, adjust the steeringwheel (Ypage 103) and the exterior mirrors(Ypage 105).

The operating safety of your vehicle may be
restricted.
You could lose control of the vehicle, for
example:
Rwhen braking
Rin the event of abrupt steering maneuvers
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar
incident, contact a qualified specialist work-
shop immediately. Do not drive any further.
You should have all work involving the bat-
tery carried out at a qualified specialist
workshop.
For further information about ABS and ESP®,see (Ypage 60) and (Ypage 65).
GWARNING
Electrostatic build-up can lead to the crea-
tion of sparks, which could ignite the highly
explosive gases of a battery. There is a risk
of an explosion.
Before handling the battery, touch the vehi-
cle body to remove any existing electrostatic
build-up.
The highly flammable gas mixture forms whencharging the battery as well as when jump-starting.
Always make sure that neither you nor the bat-tery is electrostatically charged. A build-up ofelectrostatic charge can be caused, for exam-ple:
Rby wearing clothing made from syntheticfibers
Rdue to friction between clothing and seats
Rif you push or pull the battery across thecarpet or other synthetic materials
Rif you wipe the battery with a cloth
GWARNING
During the charging process, a battery pro-
duces hydrogen gas. If a short circuit occurs
or sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
RMake sure that the positive terminal of a
connected battery does not come into
contact with vehicle parts.
RNever place metal objects or tools on a
battery.
RIt is important that you observe the
described order of the battery terminals
when connecting and disconnecting a bat-
tery.
RWhen jump-starting, make sure that the
battery poles with identical polarity are
connected.
RIt is particularly important to observe the
described order when connecting and dis-
connecting the jumper cables.
RNever connect or disconnect the battery
terminals while the engine is running.
GWARNING
Battery acid is caustic. There is a risk of
injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash away battery acid immedi-
ately with plenty of clean water and seek
medical attention.
HEnvironmental note
Batteries contain pollutants.
It is illegal to dispose of
them with the household
rubbish. They must be col-
lected separately and dis-
posed of in an environmen-
tally responsible recycling
system.
Dispose of batteries in an
environmentally responsible
manner. Take discharged
batteries to a qualified spe-
cialist workshop or to a col-
lection point for used bat-
teries.

Tire and Loading Information placard
CRecommended tire pressures
The Tire and Loading Information placard is onthe B-pillar on the driver's side (Ypage 303).
The Tire and Loading Information placard con-tains the recommended tire pressures for coldtires. The recommended tire pressures arevalid for the maximum permissible load and upto the maximum permissible vehicle speed.
Tire pressure table
The tire pressure table is on the inside of thefuel filler flap. It shows the tire pressure for alltires permitted at the factory for this vehicle;see illustration (example).
The tire pressure table contains the recom-mended pressures for cold tires for variousoperating conditions, i.e. differing load andspeed conditions.
If a tire size precedes a tire pressure, the fol-lowing tire pressure information is only validfor that tire size; see illustration (example).
The load conditions "partially laden" and "fullyladen" are defined in the table for differentnumbers of occupants and amounts of lug-gage. The actual number of seats may differ.
Some tire pressure tables show only the rimdiameters instead of the full tire size, e.g.R18.Rim diameter is part of the tire size and can befound on the tire sidewall (Ypage 307).
If the tire pressures have been set to the lowervalues for lighter loads and/or lower roadspeeds, the pressures should be reset to thehigher values:
Rif you want to drive with an increased loadand/or
Rif you want to drive at higher road speeds
The tire pressures for increased loads and/orhigher road speeds, shown in the tire pressuretable, may have a negative effect on drivingcomfort.
If the tire pressure is not set correctly, this canlead to an excessive build-up of heat and asudden loss of pressure.
For more information, contact a qualified spe-cialist workshop.
