time. Make sure you observe the notes on

MOExtended tires (run-ꢁat tires)

(/ page 291).

With MOExtended tires (run-ꢁat tires), you can

continue to drive your vehicle even if there is a

total loss of pressure in one or more tires. How-

ever, the tire aꢃected must not show any clearly

visible damage.

You can recognize MOExtended tires by the

MOExtended marking which appears on the side

wall of the tire.

Vehicles with tire pressure loss warning system:

MOExtended tires may only be used in conjunc-

tion with an activated tire pressure loss warning

system.

Vehicles with tire pressure monitoring system:

MOExtended tires may only be used in conjunc-

tion with an activated tire pressure monitoring

system.

If a pressure loss warning message appears in the

Do not exceed the speciꢀed maximum

speed of the MOExtended tires.

Vehicles with a TIREFIT kit: you can repair the

tire so that it is possible to continue the jour-

ney for a short period of time. To do this, use

the TIREFIT kit (/ page 292).

VVehicles with Mercedes me connect: you can

make a call for breakdown assistance via the

overhead control panel in the case of a break-

Have the tire sealant bottle replaced in a qualiꢀed

specialist workshop every ꢀve years.

If you come into contact with the tire sealant,

observe the following:

#

Rinse oꢃ the tire sealant from your skin

immediately using water.

#

Do not remove any foreign objects which have

entered the tire.

#

If tire sealant gets into your eyes, thor-

oughly rinse out the eyes using clean

water.

#

If tire sealant has been swallowed, imme-

diately rinse out the mouth thoroughly

and drink plenty of water. Do not induce

vomiting and seek medical attention

immediately.

#

Change out of any clothes contaminated

with tire sealant immediately.

If allergic reactions occur, seek medical

attention immediately.

On/Oꢃ switch 3.

Please note that tire sealant may leak out when

unscrewing the ꢀlling hose.

The tire is inꢁated. First, tire sealant is pum-

ped into the tire. The pressure may brieꢁy rise

Drive forwards or in reverse very slowly for

approximately 33 ꢂ (10 m).

Pump up the tire again.

#

Aꢂer a maximum of ten minutes the tire pres-

sure must be at least 200 kPa (2.0 bar/

Do not switch oꢃ the tire inꢁation compressor

during this phase!

#

Let the tire inꢁation compressor run for a max-

imum of ten minutes.

WARNING Risk of accident due to the

speciꢀed tire pressure not being achieved

The tire should then have attained a tire pres-

sure of at least 200 kPa (2.0 bar/29 psi).

If the speciꢀed tire pressure is not achieved

aꢂer the speciꢀed time, the tire is too badly

damaged. The tire sealant cannot repair the

tire in this instance.

The braking characteristics as well as the driv-

ing characteristics may be greatly impaired.

If tire sealant leaks out, make sure you clean the

aꢃected area as quickly as possible. It is prefera-

ble to use clean water.

If you get tire sealant on your clothing, have it

cleaned as soon as possible with perchloroethy-

lene.

ENVIRONMENTAL NOTE Environmental

pollution caused by environmentally irre-

sponsible disposal

A tire temporarily sealed with tire sealant

impairs the handling characteristics and is not

suitable for higher speeds.

The braking and driving characteristics may be

greatly impaired.

Tire sealant contains pollutants.

#

Do not continue driving.

Consult a qualiꢀed specialist workshop.

#

Adapt your driving style accordingly and

drive carefully.

Do not exceed the maximum speed limit

with a tire that has been repaired using

tire sealant.

Have the tire sealant bottle disposed of

professionally, e.g. at an authorized

Mercedes-Benz Center.

#

In cases such as the one mentioned above, con-

tact an authorized Mercedes-Benz Center. Or call

1-800-FOR-MERCedes (in the USA) or

1-800-387-0100 (in Canada).

#

Stow the tire sealant bottle and the tire inꢁa-

tion compressor.

#

Observe the maximum permissible speed for a

tire sealed with tire sealant 50 mph

(80 km/h).

#

Pull away immediately.

#

Correct the tire pressure if it is still at least

130 kPa (1.3 bar/19 psi). See the Tire and

Loading Information placard on the B‑pillar on

the driver's side or the tire pressure table in

the fuel ꢀller ꢁap for values.

To increase the tire pressure: switch on the

tire inꢁation compressor.

Stop driving aꢂer approximately ten minutes

and check the tire pressure using the tire

inꢁation compressor.

The tire pressure must now be at least

130 kPa (1.3 bar/19 psi).

#

A discharged battery may freeze at tempera-

tures slightly above or below freezing point.

When charging using a battery charger without

a maximum charging voltage, the battery or

the on-board electronics may be damaged.

During starting assistance or battery charging,

battery gas can be released.

Always allow a battery to thaw before

charging it or performing starting assis-

tance.

WARNING Risk of explosion due to igniting

hydrogen gas

If the indicator/warning lamps in the instrument

cluster do not light up at low temperatures, it is

very likely that the discharged battery has frozen.

In this case you may neither jump-start the vehi-

cle nor charge the battery.

If there is a short circuit or sparks start to

form when charging a battery, there is a dan-

ger of the hydrogen gas igniting.
