Notes on at tyres

WARNING Risk of accident due to a at

tyre

A at tyre severely aects the driving charac-

teristics as well as steering and braking.

tyres that do not feature run-at characteris-

tics:

Do not drive on with a at tyre.

Change the at tyre immediately with an

emergency spare wheel or spare wheel.

Alternatively, consult a qualied special-

ist workshop.

Run-at tyres:

Observe the information and warning

notes on MOExtended tyres (run-at

tyres).

In the event of a at tyre, the following options are

available depending on your vehicle's equipment:

Vehicles with MOExtended tyres: it is possible

to continue the journey for a short period of

time. Make sure you observe the notes on

MOExtended tyres (run-at tyres)

(/ page 597).

Vehicles with a TIREFIT kit: you can seal the

tyre so that it is possible to continue the jour-

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

the TIREFIT kit (/ page 598).

Notes on MOExtended tyres (run-at tyres)

WARNING Risk of accident when driving in

limp-home mode

Driving in emergency mode impairs the han-

dling characteristics of the vehicle.

Do not exceed the permissible maximum

speed of the MOExtended tyres.

Avoid any abrupt steering and driving

manoeuvres as well as driving over

obstacles (kerbs, pot holes, o-road).

This applies, in particular, to a loaded

vehicle.

Stop driving in the emergency mode if

you notice:

banging noise

vehicle vibration

smoke which smells like rubber

continuous ESP

intervention

cracks in the tyre sidewalls

Aer driving in emergency mode, have

the rims checked by a qualied specialist

workshop with regard to their further

use.

The defective tyre must be replaced in

every case.

With MOExtended tyres (run-at tyres), you can

continue to drive your vehicle even if there is a

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

ever, the tyre aected must not show any clearly

visible damage.

You can recognise MOExtended tyres by the

MOExtended marking which appears on the side

wall of the tyre.

Vehicles with tyre pressure loss warning system:

MOExtended tyres may only be used in conjunc-

tion with an activated tyre pressure loss warning

system.

Vehicles with tyre pressure monitoring system:

MOExtended tyres may only be used in conjunc-

tion with an activated tyre pressure monitoring

system.

If a pressure loss warning message appears in the

driver's display, proceed as follows:

Check the tyre for damage.

If driving on, observe the following notes.

Driving distance possible in emergency mode

aer the pressure loss warning:

Load condition Driving distance possi-

ble in emergency mode

Partially laden 80 km

Fully laden 30 km

The driving distance possible in emergency mode

may vary depending on the driving style. Observe

the maximum permissible speed of 80 km/h.

If a tyre has gone at and cannot be replaced with

an MOExtended tyre, you can use a standard tyre

as a temporary measure.
