HEnvironmental note
Hav ethe used tire sealant bottle dispose dof
professionally, e.g .ataqualified specialist
workshop.
If at ire pressure of 200 kPa (2.0 bar/29 psi) has
been attaine dafter ten minutes:
XSwitch off the tire inflation compressor.
XUnscrew the fille rhosef romt he valve of the
faulty tire.
XStow the tire sealant bottle and the tire infla-
tio nc ompressor.
XPul lawa yimmediately.
XStop after drivin gfor approximately ten
minute sand check the tire pressure with the
tire inflation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi).
GWARNING
If the required tire pressure is not reached
after drivin gfor as hort period, the tire is too
badl ydamaged .The tire sealant canno trepair

XTo increase the tire pressure: switch on the
tire inflation compressor.
XTo reduc ethe tire pressure: depress pres-

Jump-starting
For the jump-starting procedure, use only the jump-starting connection point in the engine com-
partment,consisting of apositive terminal and aground point.
All vehiclese xcept vehiclesw ithalithium-ion battery:
GWARNING
Battery acid is caustic. There is arisk 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 immediately with plenty of
clean water and seek medical attention.
GWARNING
During charging and jump-starting, explosive gases can escape from the battery. There is arisk
of an explosion.
Particularly avoid fire, open flames, creating sparks and smoking. Ensure there is sufficient ven-
tilation while charging and jump-starting. Do not lean over abattery.
GWARNING
During the charging process, abattery produces hydrogen gas. If ashort circuit occurs or sparks
are created, the hydrogen gas can ignite. There is arisk of an explosion.
RMake sure that the positive terminal of aconnected battery does not come into contact with
vehicle parts.
RNever place metal objects or tools on abattery.
RIt is important that you observe the described order of the battery terminals when connecting
and disconnecting abattery.
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 disconnecting
the jumper cables.
RNever connect or disconnectt he battery terminals while the engine is running.
GWARNING
Ad ischarged battery can freeze at temperatures below freezing point. When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is arisk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
If, at low temperatures, the indicator lamps/warning lamps in the instrument cluster do not light up,
it is highly likely that the discharged battery has frozen.Int his case, you may neither charge the
battery nor jump-start the vehicle. The service life of athawed-out battery may be shorter. The
starting characteristicsc an be impaired, particularly at low temperatures. Have the thawed-out
battery checked at aqualified specialist workshop.
All vehicles:
!Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.

The tire pressure monitor hasayellow warning
lamp in the instrument cluster for indicating
pressure loss or amalfunction. Whether the
warning lamp flashes or lights up indicates
whether atire pressure is too low or the tire
pressure monitor is malfunctioning:
Rif the warning lamp is lit continuously, the tire
pressure on one or more tires is significantly
too low. The tire pressure monitor is not mal- functioning.
Rif the warning lamp flashes for around a
minute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
In addition to the warning lamp, amessage
appears in the multifunction display.O bserve
the information on display messages
(
Ypage 241).
It may take up to ten minutes for amalfunction
of the tire pressure monitor to be indicated. A
malfunction will be indicated by the tire pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
malfunction has been rectified, the tire pressure
warning lamp goes out after afew minutes of
driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at agas station with apressure gauge. The
tire pressures shown by the on-board computer
refer to those measured at sea level. At high
altitudes, the tire pressure values indicated by a
pressure gauge are higher than those shown by the on-board computer. In this case, do not
reduce the tire pressures.
The operation of the tire pressure monitor can
be affected by interferenc efrom radio transmit-
ting equipment (e.g. radio headphones, two-way
radios) that may be being operated in or near the vehicle.
Checking the tire pressur eelectroni-
cally
XMake sure that the SmartKey is in position 2
in the ignition lock (Ypage 131).
XPress òon the steerin gwheel to call up
the menu list.
XPress 9or: on the steerin gwheel to
select the Servicemenu.
XConfirm by pressing aon the steering
wheel.
XPress 9or: to select Tire Pres‐sure.
XPressato confirm.
The multifunction display shows the current
tire pressure of each wheel.
If the vehicle was parked for longer than
20 minutes, the following message appears:

After ateach-in process, the tire pressure mon-
itor automatically detect snew wheels or new
sensors. As long as aclear allocation of the tire
pressure value to the individual wheels is not
possible, the Tire
PressureMonitorActivemessage is shown instead of the tire pressure
display.The tire pressures are already being
monitored.
Tire pressur emonitor warning mes-
sages
If the tire pressure monitor detect sapressure
loss in one or more tires, awarning message is
shown in the multifunction display.T he yellow
tire pressure warning lamp then lights up.
RIf the Please Correct Tire Pressuremessage appears in the multifunction display,
the tire pressure in at least one tire is too low.
The tire pressure must be corrected when the opportunit yarises.
RIf the Check Tiresmessage appears in the
multifunction display,t he tire pressure in one
or more tires has dropped significantly. The
tires must be checked.
RIf the WarningTireMalfunctionmessage
appears in the multifunction display,t he tire
pressure in one or more tires has dropped
suddenly. The tires must be checked.
Be sure to observe the instructions and safety
notes in the display messages in the "Tires" sec- tion (
Ypage 241).
If the wheel positions on the vehicle are rotated, the tire pressures may be displayed for the
wrong positions for ashort time. This is rectified
after afew minutes of driving, and the tire pres-
sures are displayed for the correctp ositions.
Restarting the tire pressuremonitor
When you restart the tire pressure monitor, all
existin gwarning messages are deleted and the
warning lamps go out. The monitor uses the cur-
rently set tire pressures as the reference values
