Run-flat tires

You can continue driving with a damaged tire at speeds up to 50 mph/80 km/h.

Do not continue driving without run-flat tires
If the vehicle is not equipped with run-flat tires as provided at the factory, do not continue driving.

Continuing to drive could cause severe accidents.◀

Continued driving with a flat tire

If continuing to drive with a damaged tire:

1. Avoid sudden braking and steering maneuvers.

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

If the defective tire continues to lose pressure, its position will be indicated to you on the Control Display.

3. At the next opportunity, check the inflation pressure in all four tires.

If the tire inflation pressure in all four tires is correct, the Flat Tire Monitor may not have been initialized. In this case, initialize the system.

Possible driving distance with complete loss of tire inflation pressure:

▷ With a light load:

1 to 2 people without luggage:

Approx. 155 miles/200 km.
▷ With a medium load:

2 persons, cargo area full, or 4 persons without luggage:

Approx. 94 miles/150 km.
▷ With a full load:

4 or more persons, cargo area full:

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., reduced lane stability during braking, a longer braking distance, and altered self-steering properties. Adjust your driving style accordingly.

Avoid abrupt steering maneuvers or driving 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 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.

A loss of tire inflation pressure results in a change in the handling characteristics, e.g., reduced lane stability during braking, a longer braking distance and altered self-steering properties.◀

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 continue driving, and contact your service center.◀
