Low tire pressure message

The warning lights come on in yellow

and red. A message appears on the

Control Display. In addition, a signal

sounds.

▷ There is a flat tire or a major loss in tire in‐

flation pressure.

▷ The system was not reset. The system

therefore issues warnings in case of devia‐

tions from the tire inflation pressures

stored last.

1. Reduce your speed and stop cautiously.

Avoid sudden braking and steering maneu‐

vers.

2. Check whether the vehicle is fitted with

regular tires or run-flat tires.

Run-flat tires, refer to page 98, are la‐

beled with a circular symbol containing the

letters RSC marked on the tire sidewall.

Do not continue driving without run-flat

tires

Do not continue driving if the vehicle is not

equipped with run-flat tires; continued driving

may result in serious accidents.◀

When a flat tire is indicated, DSC Dynamic Sta‐

bility Control is switched on if necessary.

Actions in the event of a flat tire

Normal tires

1.

Identify the damaged tire.

Do this by checking the air pressure in all

four tires.

If the tire inflation pressure in all four tires

is correct, the Tire Pressure Monitor may

not have been reset. Reset the system.

If an identification is not possible, please

contact the service center.

2. Rectify the flat tire.

The use of tire sealant can damage the

TPM electronics. In this case, have the

electronics checked at the next opportu‐

nity and have them replaced if necessary.

Run-flat tires

You can continue driving with a damaged tire

at speeds up to 50 mph/80 km/h.

Continued driving with a flat tire

If continuing to drive with a damaged tire:

1. Avoid sudden braking and steering maneu‐

vers.

2. Do not exceed a speed of 50 mph/80 km/h.

3. Check the air pressure in all four tires at

the next opportunity.

If the tire inflation pressure in all four tires

is correct, the Tire Pressure Monitor may

not have been reset. Reset the system.

Possible driving distance with complete loss of

tire inflation pressure:

The possible driving distance after a loss of tire

inflation pressure depends on the cargo load

and the driving style and conditions.

For a vehicle containing an average load, the

possible driving distance is approx.

50 miles/80 km.

When the vehicle is driven with a damaged tire,

its handling characteristics change, e.g., re‐

duced lane stability during braking, a longer

braking distance, and altered self-steering

properties. Adjust your driving style accord‐

ingly. Avoid abrupt steering maneuvers or driv‐

ing over obstacles, e. g., curbs, potholes, etc.

Because the possible driving distance de‐

pends on how the vehicle is used during the

trip, the actual distance may be smaller or

greater depending on the driving speed, road

conditions, external temperature, cargo load,

etc.

Continued driving with a flat tire

Drive moderately and do not exceed a

speed of 50 mph/80 km/h.
