Refueling
Important safety notes
GWARNING
Fuel is highly flammable. Risk of fire and
explosion by improper handling of fuel.
You must avoid fire, open flames, smoking
and creating sparks. Switch off the ignition
before refueling and, if present, switch off
the auxiliary heating.
GWARNING
Fuels are toxic and harmful to health. There
is a risk of injury.
You must avoid fuels coming into contact
with skin, eyes and clothes or being swal-
lowed.
Do not inhale the fuel vapors. Keep children
away from fuels.
Keep doors and windows closed during the
refueling process.
If you or others come into contact with fuel,
observe the following points:
RImmediately rinse the fuel off your skin
with soap and water.
RIf you get fuel into your eyes, immediately
rinse your eyes throughly with clean
water. Seek medical attention immedi-
ately.
RSeek medical attention immediately if fuel
has been swallowed. Do not induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic charging can lead to the crea-
tion of sparks and ignite fuel vapor. There is
a risk of fire and explosion.
Touch the metallic body of the vehicle
before you open the fuel filler cap or handle
the pump nozzle. Any possible electrostatic
charge present will in this way be depleted.
144Refueling
Driving and parking

Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
Do not get into the vehicle again during therefueling process. Otherwise, electrostaticcharge could build up again.
!Do not use diesel to refuel vehicles with agasoline engine. Do not switch on the igni-tion if you accidentally refuel with the wrongfuel. Otherwise, the fuel will enter the fuelsystem. Even small amounts of the wrongfuel could result in damage to the fuel sys-tem and the engine. Notify a qualified spe-cialist workshop and have the fuel tank andfuel lines drained completely.
!Overfilling the fuel tank could damage thefuel system.
!Take care not to spill any fuel on paintedsurfaces. You could otherwise damage thepaintwork.
!Use a filter when adding fuel from a fuelcan. The fuel lines and/or the fuel injectionsystem could otherwise be blocked by parti-cles from the fuel can.
If you overfill the fuel tank, fuel could sprayout when the fuel pump nozzle is removed.
For further information on fuel and fuel quality(Ypage 322).

HEnvironmental note
Have the used tire sealant bottle disposed
of professionally, e.g. at a qualified special-
ist workshop.
If a tire pressure of 180 kPa(1.8 bar/26 psi)has been achieved after a maximum period often minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of thefaulty tire.
XStow the tire sealant bottle and the tireinflation compressor.
XPull away immediately.
XStop after driving for approximately tenminutes and check the tire pressure withthe tire inflation compressor.The tire pressure must now be at least130 kPa (1.3 bar/19 psi).
GWARNING
If the required tire pressure is not reached
after driving for a short 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 a risk of
accident.
Do not continue driving. Contact a qualified
specialist workshop.
iIn cases such as the one mentionedabove, contact an authorized Mercedes-Benz Center. Or call 1-800-FOR-MERCedes(in the USA) or 1-800-387-0100 (in Canada).
XCorrect the tire pressure if it is still at least130 kPa (1.3 bar/19 psi). See the Tire andLoading Information placard on the driver'sside B-pillar or the tire pressure table in thefuel filler flap for values.
XTo increase the tire pressure:switch onthe tire inflation compressor.
XTo reduce the tire pressure:depress pres-sure release buttonmnext to pressuregagen.
XWhen the tire pressure is correct, unscrewthe filler hose from the valve of the sealedtire.
XScrew the valve cap onto the tire valve ofthe sealed tire.
XPull the tire sealant bottle out of the tireinflation compressor.
The filler hose remains attached to the tiresealant bottle.
XDrive to the nearest qualified specialistworkshop and have the tire changed there.
XHave the tire sealant bottle replaced assoon as possible at a qualified specialistworkshop.
XHave the tire sealant bottle replaced everyfour years at a qualified specialist workshop.
Battery (vehicle)
Important safety notes
Special tools and expert knowledge arerequired when working on the battery, e.g.removal and installation. You should thereforehave all work involving the battery carried outat a qualified specialist workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This
can lead to function restrictions applying to
safety-relevant systems, e.g. the lighting
system, the ABS (anti-lock braking system)
or the ESP®(Electronic Stability Program).
282Battery (vehicle)
Breakdown assistance

GWARNING
During charging and jump-starting, explosive gases can escape from the battery. There is a
risk 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 a battery.
GWARNING
During the charging process, a battery produces 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 connect-
ing and disconnecting a battery.
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 disconnect-
ing the jumper cables.
RNever connect or disconnect the battery terminals while the engine is running.
GWARNING
A discharged 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 a risk of an explo-
sion.
Allow the frozen battery to thaw out before charging it or jump-starting.
!Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could bedamaged by the non-combusted fuel.
If the indicator/warning lamps do not light up at low temperatures, it is very likely that the dis-charged battery has frozen. In this case, you may neither charge the battery nor jump-start thevehicle. The service life of a thawed-out battery may be shorter. The starting characteristics canbe impaired, particularly at low temperatures. Have the thawed-out battery checked at a quali-fied specialist workshop.
Do not start the vehicle using a rapid charging device. If your vehicle's battery is discharged, theengine can be jump-started from another vehicle or from a donor battery using jumper cables.Observe the following points:
RThe battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,jump-start the vehicle using a donor battery or a jump-starting device.
RYou may only jump-start the vehicle when the engine and exhaust system are cold.
RDo not start the engine if the battery is frozen. Let the battery thaw first.
ROnly jump-start from batteries with a 12 V voltage rating.
ROnly use jumper cables which have a sufficient cross-section and insulated terminal clamps.
RIf the battery is fully discharged, leave the battery that is being used to jump-start connectedfor a few minutes before attempting to start. This charges the battery slightly.
RMake sure that the two vehicles do not touch.
286Jump-starting
Breakdown assistance

Important notes on tire pressure
GWARNING
If the tire pressure drops repeatedly, the
wheel, valve or tire may be damaged. Tire
pressure that is too low may result in a tire
blow-out. There is a risk of an accident.
RCheck the tire for foreign objects.
RCheck whether the wheel is losing air or
the valve is leaking.
If you are unable to rectify the damage, con-
tact a qualified specialist workshop.
GWARNING
If you fit unsuitable accessories onto tire
valves, the tire valves may be overloaded
and malfunction, which can cause tire pres-
sure loss. Due to their design, retrofitted tire
pressure monitors keep the tire valve open.
This can also result in tire pressure loss.
There is a risk of an accident.
Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
your vehicle onto the tire valve.
Use a suitable pressure gauge to check thetire pressure. The outer appearance of a tiredoes not permit any reliable conclusion aboutthe tire pressure. On vehicles equipped withthe electronic tire pressure monitor, the tirepressure can be checked in the on-board com-puter.
The tire temperature and pressure increasewhen the vehicle is in motion. This is depend-ent on the driving speed and the load.
Therefore, you should only correct tire pres-sures when the tires are cold.
The tires are cold:
Rif the vehicle has been parked with the tiresout of direct sunlight for at least three hoursand
Rif the vehicle has not been driven furtherthan 1 mile (1.6 km)
The tire temperature changes depending onthe outside temperature, the vehicle speedand the tire load. If the tire temperaturechanges by 18 ‡ (10 †), the tire pressurechanges by approximately 10 kPa (0.1 bar/1.5 psi). Take this into account when checking
the pressure of warm tires. Only correct thetire pressure if it is too low for the currentoperating conditions. If you check the tirepressure when the tires are warm, the result-ing value will be higher than if the tires werecold. This is normal. Do not reduce the tirepressure to the value specified for cold tires.The tire pressure would otherwise be too low.
Observe the recommended tire pressures forcold tires:
Ron the Tire and Loading Information placardon the B-pillar on the driver's side
Rin the tire pressure table on the inside of thefuel filler flap
Underinflated or overinflated tires
Underinflated tires
GWARNING
Tires with pressure that is too low can over-
heat and burst as a consequence. In addi-
tion, they also suffer from excessive and/or
irregular wear, which can severely impair the
braking properties and the driving character-
istics. There is a risk of an accident.
Avoid tire pressures that are too low in all
the tires, including the spare wheel.
Underinflated tires may:
Roverheat, leading to tire defects
Radversely affect handling
Rwear excessively and/or unevenly
Rhave an adverse effect on fuel consumption
Overinflated tires
GWARNING
Tires with excessively high pressure can
burst because they are damaged more eas-
ily by road debris, potholes etc. In addition,
they also suffer from irregular wear, which
can severely impair the braking properties
and the driving characteristics. There is a
risk of an accident.
Avoid tire pressures that are too high in all
the tires, including the spare wheel.
