Approx. 30 miles/50 km.

The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
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 depends
on how the vehicle is used during the trip, the
actual distance may be smaller or greater de‐
pending 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.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering prop‐
erties.◀

Final tire failure
Vibrations or loud noises while driving can

indicate the final failure of the tire. Reduce speed
and stop; otherwise, pieces of the tire could
come loose and cause an accident. Do not con‐
tinue driving, and contact your service center.◀

Tire Pressure Monitor TPM*

The concept

The tire inflation pressure is measured in the
four mounted tires. The system notifies you if
there is a significant loss of pressure in one or
more tires.

Functional requirements

The system must have been reset while the in‐
flation pressure was correct; otherwise, reliable
signaling of a flat tire is not ensured.

Always use wheels with TPM electronics to en‐
sure that the system will operate properly.
Reset the system after each correction of the
tire inflation pressure and after every tire or
wheel change.

System limits

Sudden tire damage
Sudden serious tire damage caused by

external influences cannot be indicated in ad‐
vance.◀

The system does not operate correctly if it has
not been reset. For example, a flat tire may be
indicated despite correct tire inflation pres‐
sures.
The system is inactive and cannot indicate a flat
tire:

If a wheel without TPM electronics is
mounted, e.g., compact wheel*.

When the TPM is disturbed by other sys‐
tems or devices with the same radio fre‐
quency.

Status display

1.

"Vehicle Info"

2.

"Vehicle status"

3.

"TPM"

The status is displayed.

Status indicator on the Control Display

The tire and system status is indicated by the
color of the tires.
A change in the tire inflation pressure during
driving is taken into account.
A correction is only necessary if this is indicated
by the TPM

Wheels, green

The tire inflation pressure is equal to the target
state.

One wheel is yellow

A flat tire or major drop in inflation pressure in
the indicated tire.
