WARNING Risk of accident due to a ꢀat

tire

A ꢀat tire severely aꢃects the driving charac-

teristics as well as the steering and braking of

the vehicle.

Tires without run-ꢀat characteristics:

#

Do not drive with a ꢀat tire.

#

Fold side reꢀectors 1 upwards to form a tri-

angle and attach at the top using upper press-

stud 2.

Change the ꢀat tire immediately with an

emergency spare wheel or spare wheel.

Alternatively, consult a qualiꢂed special-

ist workshop.

#

Fold legs 3 down and out to the side.

Tires with run-ꢀat characteristics:

WARNING Risk of accident when driving in

limp-home mode

R

Vehicles with MOExtended tires: it is possible

to continue the journey for a short period of

time. Make sure you observe the notes on

MOExtended tires (run-ꢀat tires)

#

The defective tire must be replaced in

every case.

When driving in emergency mode the handling

characteristics are impaired.

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.

(/ page 274).

#

Do not exceed the speciꢂed maximum

speed of the MOExtended tires.

R

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 275).

#

Avoid any abrupt steering and driving

maneuvers as well as driving over obsta-

cles (curbs, pot holes, oꢃ-road). This

applies, in particular, to a loaded vehicle.

You can recognize MOExtended tires by the

MOExtended marking which appears on the side

wall of the tire.

Vehicles with Mercedes me connect: you can

make a call for breakdown assistance via the

overhead control panel in the case of a break-

down (/ page 239).

WARNING Risk of injury and poisoning

from tire sealant

NOTE Overheating due to the tire inꢀation

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.

Do not run the tire inꢀation compressor

for longer than ten minutes without inter-

ruption.

Comply with the manufacturer's safety notes on

the sticker on the tire sealant bottle.

If you come into contact with the tire sealant,

observe the following:

Have the tire sealant bottle replaced in a qualiꢂed

specialist workshop every ꢂve years.

#

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.

#

Remove sticker 2 from the tire sealant bottle

and aꢄx it near the valve on the wheel with

the faulty tire.

#

If tire sealant has been swallowed, imme-

diately rinse out the mouth thoroughly
