WARNING Risk of accident when driving

in emergency mode

In the event of a flat tire, the following options

are available depending on your vehicle's equip‐

ment:

When driving in emergency mode, the han‐

dling characteristics are impaired. e.g. when

cornering, when accelerating strongly and

when braking.

#

R

Vehicles with MOExtended tires: it is pos‐

sible to continue the journey for a short

period of time. Make sure you observe the

notes on MOExtended tires (run-flat tires)

(/ page 438).

With MOExtended tires (run-flat tire), 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 affected 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.

#

Do not exceed the permissible maxi‐

mum speed for MOExtended tires.

Avoid any abrupt steering and driving

maneuvers as well as driving over

obstacles (curbs, pot holes, off-road).

This applies, in particular, to a loaded

vehicle.

Stop driving in the emergency mode if

you notice:

R

Vehicles with a TIREFIT kit: you can repair

#

the tire so that it is possible to continue the

journey for a short period of time. To do this,

use the TIREFIT kit (/ page 439).

Vehicles with Mercedes me connect: you

can make a call for breakdown assistance via

the overhead control panel in the case of a

Gloves (depending on the vehicle equipment)

If a pressure loss warning message appears in

the multifunction display, proceed as follows:

You can use TIREFIT tire sealant to seal perfora‐

tion damage of up to 0.16 in (4 mm), particularly

those in the tire contact surface. You can use

TIREFIT in outside temperatures down to -4 °F

(-20 °C).

WARNING Risk of injury and poisoning

from tire sealant

NOTE Overheating due to the tire infla‐

tion compressor running too long

*

The tire sealant is harmful and causes irrita‐

tion. Do not allow it to come into contact

with the skin, eyes or clothing, and do not

swallow it. Do not inhale tire sealant fumes.

Keep the tire sealant away from children.

#

Affix part 1 of the TIREFIT sticker to the

instrument cluster within the driver's field of

vision.

Affix part 2 of the TIREFIT sticker near the

valve on the wheel with the faulty tire.

#

Do not run the tire inflation compressor

for longer than ten minutes without

interruption.

If you come into contact with the tire sealant,

observe the following:

Comply with the manufacturer's safety notes on

the sticker on the tire inflation compressor.

Have the tire sealant bottle replaced in a quali‐

fied specialist workshop every five years.

#

Rinse off the tire sealant from your skin

immediately using water.

Do not switch off the tire inflation compres‐

sor during this phase.

#

Let the tire inflation compressor run for a

maximum of ten minutes.

The tire should then have attained a tire

pressure of at least 200 kPa (2.0 bar/

29 psi).

If tire sealant leaks out, make sure you clean the

affected 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.

#

Remove the valve cap from valve 7 on the

faulty tire.

#

Screw filling hose 8 onto valve 7.

Insert plug 4 into a 12 V socket in your

vehicle.

Switch on the ignition.

Press on and off switch 3 on the tire infla‐

tion compressor.

The tire inflation compressor is switched on.

The tire is inflated. First, tire sealant is pum‐

ped into the tire. The pressure may briefly

rise to approximately 500 kPa (5 bar/73 psi).

If, after ten minutes, a tire pressure of

200 kPa (2.0 bar/29 psi) has not been

attained:

#

Pull plug 4 with the cable and hose 5 out

#

of the tire inflation compressor housing.

#

Switch off the tire inflation compressor.

Push the plug of hose 5 into flange 6 of

tire sealant bottle 1 until the plug engages.

Place tire sealant bottle 1 head downwards

into recess 2 of the tire inflation compres‐

sor.

#

Unscrew the filling hose from the valve of the

faulty tire.

Please note that tire sealant may leak out when

unscrewing the filling hose.

WARNING Risk of accident from driving

with sealed tires

After a maximum of ten minutes the tire

pressure must be at least 200 kPa (2.0 bar/

29 psi).

#

Therefore, place the filling hose in the

plastic bag that contained the TIREFIT

kit.

A tire temporarily sealed with tire sealant

impairs driving characteristics and is not

suitable for higher speeds.

&

WARNING Risk of accident due to the

specified tire pressure not being ach‐

ieved

#

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.

ENVIRONMENTAL NOTE Environmental

pollution caused by environmentally irre‐

sponsible disposal

+

If the specified tire pressure is not achieved

after the specified time, 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 braking and han‐

dling characteristics.

#

Tire sealant contains pollutants.

#

Have the tire sealant bottle disposed of

professionally, e.g. at an authorized

Mercedes-Benz Center.

#

Observe the maximum permissible speed for

a tire sealed with tire sealant 50 mph

(80 km/h).

Affix the upper section of the TIREFIT sticker

to the instrument cluster in a location where

it will be easily seen by the driver.

#

Do not drive on.

Consult a qualified specialist workshop.

Stow the tire sealant bottle and the tire infla‐

tion compressor.

Pull away immediately.

#

If, after ten minutes, a tire pressure of

200 kPa (2.0 bar/29 psi) has been attained:

#

Switch off the tire inflation compressor.

Breakdown assistance 443

#

Stop driving after approximately ten minutes

and check the tire pressure using the tire

inflation compressor.

The tire pressure must now be at least

130 kPa (1.3 bar/19 psi).

Loading Information placard on the B‑pillar

on the driver's side or the tire pressure table

in the fuel filler flap for values.

To increase the tire pressure: switch on

the tire inflation compressor.

Pull the tire sealant bottle out of the tire

inflation compressor.

The filling hose stays on the tire sealant bot‐

tle.

Drive to the nearest qualified specialist work‐

shop and have the tire, tire sealant bottle

and filling hose replaced there.

#

&

WARNING Risk of accident due to the

specified tire pressure not being reached

If the specified tire pressure is not reached

after a brief drive, the tire is too badly dam‐

aged. The tire sealant cannot repair the tire

in this instance.

Damaged tires and tire pressure that is too

low can significantly impair the braking prop‐

erties and the handling characteristics.

Notes on the 12 V battery

&

WARNING Risk of an accident due to

work carried out incorrectly on the bat‐

tery

Work carried out incorrectly on the battery

can, for example, lead to a short circuit. This

can lead to function restrictions in safety-rel‐

evant systems, for example the lighting sys‐

tem, ABS (anti-lock braking system) or ESP^®

(Electronic Stability Program). The operating

safety of your vehicle may be restricted.

#

Do not continue driving.

Consult a qualified specialist workshop.

#

To reduce the tire pressure: press pressure

release button 1 next to manometer 2.

When the tire pressure is correct, unscrew

the filling hose from the valve of the sealed

tire.

#

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).

#

Screw the valve cap onto the valve of the

sealed tire.

#

Correct the tire pressure if it is still at least

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