surfaces. You could otherwise damage the
paintwork.
! Use afilter when refueling from afuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
Do not get into the vehicle againd uringthe

WARNING
If the required tire pressure is not reached
after driving for ashort period, the tire is too
badly damaged. The tire sealant cannot repair
the tire in this instance. Damaged tires and a
tire pressure that is too low can significantly
impair the vehicle's braking and driving
characteristics. There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.
X Correct the tire pressure if it is still at least
130 kPa (1.3 bar/19 psi) (for the values,
see the Tire and Loading Information
placard on the driver's side B-pillar or tire
pressure table on the fuel filler flap).

sealant bottle.
X Stow the tire sealant bottle and the tire
inflation compressor.
X Drive to the nearest qualified specialist
workshop and have the tire changed there.
X Have the tire sealant bottle and the filler
hose replaced as soon as possible at a
qualified specialist workshop.
X Have the tire sealant bottle replaced every
four years at aqualified specialist

Important safety notes
Special tools and expert knowledge are
required when working on the battery, e.g.
removal and installing. You should therefore
have all work involving the battery carried out
at aq ualified specialist workshop. Battery (vehicle)

Jump-starting
For the jump-starting procedure, use only the jump-starting connection point, consisting of a
positive terminal and an earth point, in the engine compartment. G
WARNING
Battery acid is caustic. There is arisk of injury.
Avoid contact with the skin, eyes or clothing. Do not inhale any battery gases. Do not lean over
the battery. Keep children away from batteries. Wash battery acid immediately with water and
seek medical attention. G
WARNING
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
ventilation while charging and jump-starting. Do not lean over abattery. G
WARNING
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.
R Make sure that the positive terminal of aconnected battery does not come into contact with
vehicle parts.
R Never place metal objects or tools on abattery.
R It is important that you observe the described order of the battery terminals when connecting
and disconnecting abattery.
R When jump-starting, make sure that the battery poles with identical polarity are connected.
R It is particularly important to observe the described order when connecting and disconnecting
the jumper cables.
R Never connect or disconnectt he battery terminals while the engine is running.G
WARNING
Ad ischarged battery can freeze at temperatures below freezin gpoint .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.
! Avoid repeated and lengthy startinga ttempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
If, at low temperatures, the indicator lamps/warning lamps in the instrumentc luster do not
light up, it is highly likely that the discharged battery has frozen .Inthis case you may neither
jump-start the vehicle nor charge the battery. The service life of athawed-out battery may be
shorter. The startingc haracteristics can be impaired, particularly at low temperatures. Have
the thawed-out battery checked at aqualified specialist workshop. Jump-starting

X Read th etirep ressure and compar eitwith
th er ecommended value on th eTire and

X If necessary, increas ethe tirep ressure to
th er ecommended value ( Ypage 315).
X If th etirep ressure is to ohigh,release air
by pressin gdown th emetal pin in th evalve

X Screw the valve cap onto the valve.
X Repeatt hese steps for the other tires. Tire pressurel
oss warning system
General notes While the vehicle is in motion, the tire
pressure loss warning system monitors the
set tire pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in atire. If the speed
of rotation of awheel changes as aresult of
al oss of pressure, acorresponding warning
message will appearint he multifunction
display.
You can recognizet he tire pressure loss
warning by the Run Flat Indicator Active Press 'OK' to Restart message
which appears in the Service menu of the
multifunction display. Further information on
the message displayc an be found under
"Restarting the tire pressure loss warning
system" (Y page 319). Important safety notes The tire pressure warning system does not
warn you of an incorrectly set tire pressure.
Observe the notes on the recommended tire
pressure (Y
page 315).
The tire pressure loss warning does not
replace the need to regularly check the tire
pressure. An even loss of pressure on several
tires at the same time cannot be detected by
the tire pressure loss warning system.
The tire pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the
tire is penetrated by aforeign object.Int he
event of asudden loss of pressure, bring the
vehicle to ahalt by braking carefully. Avoid
abrupt steering maneuvers.
The function of the tire pressure loss warning
system is limited or delayed if:
R snow chains are mounted on your vehicle's
tires.
R road conditionsa re wintry.
R you are driving on sand or gravel.
R you adopt avery sporty driving style
(corneringath igh speeds or driving with
high rates of acceleration).
R you are driving with aheavy load (in the
vehicle or on the roof).
Restarting the tire pressurel oss
warning system Restart the tire pressure loss warning system
if you have:
R
changed the tire pressure
R changed the wheels or tires
R mounted new wheels or tires
X Before restarting, make sure that the tire
pressures are set properly on all four tires
for the respective operating conditions.
The recommended tire pressure can be
found on the Tire and Loading Information
placard on the B-pillar on the driver's side.
Additionally, atire pressure table is
attached to the fuel filler flap. The tire Tire pressure

The GAWR is the maximu mgross axle weight
rating. The actua lloa donana xle must never
exceed the gross axle weight rating. The
gross axle weight rating can be found on the
vehicl eidentification plate on the B-pillar on
the driver's side. Speed rating
The spee drating is part of the tire
identification. It specifies the spee drange for
which the tire is approved. GVW (Gross Vehicle Weight)
The gross vehicl eweight includes the weight
of the vehicl eincluding fuel ,tools, the spare

on the B-pillar on the driver's side. GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permissible gross
weight of afully loaded vehicle (the weight of
the vehicle including all accessories,
occupants, fuel, luggage and the drawbar
noseweight, if applicable). The gross vehicle
weight rating is specified on the vehicle
identification plate on the B-pillar on the
driver's side. Maximum loaded vehicle weight
The maximum weight is the sum of:
R the curb weight of the vehicle
R the weight of the accessories
R the load limit
R the weight of the factory installed optional
equipment Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa
corresponds to 1psi. Another unit for tire
pressure is bar. 100 kilopascal (kPa) is the
equivalent of 1bar. Load index
In addition to th eload-bearing index ,the load
index may also be imprinted on th esidewall
of th etire. This specifie sthe load-bearing
capacity more precisely. Curb weight
The weight of avehicle with standard
equipment including the maximum capacity
of fuel, oil and coolant. It also includes the air-
conditioning system and optional equipment
if these are installed in the vehicle, but does
not include passengers or luggage. Maximum load rating
The maximum load rating in kilograms or
pounds is the maximum weight for which a
tire is approved. Maximum permissible tire pressure
Maximum permissible tire pressure for one
tire. Maximum load on one tire
Maximum load on one tire. This is calculated
by dividing the maximum axle load of one axle
by two. PSI (pounds per squarei
