Controls
Safety
A vehicle with a damaged tire reacts differ‐
ently, e.g., it has reduced lane stability during
braking, a longer braking distance and different
self-steering properties. Adjust your driving
style accordingly. Avoid abrupt steering ma‐
neuvers or driving over obstacles, e.g., curbs,
potholes, etc.
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.
The tire pressure gage of the Mobility Sys‐
tem, refer to page 208, can possibly be
used for this purpose.
Because the possible driving distance de‐
pends on how the vehicle is used during the
trip, the actual distance may be shorter or lon‐
ger depending on the driving speed, road con‐
ditions, external temperature, cargo load, etc.
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.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
If an identification is not possible, please
contact the service center.
Your car handles differently when you lose tire
inflation pressure, e.g., your lane stability is re‐
duced when braking, braking distances are
longer and the self-steering properties will
change.◀
2. Fix the flat tire where applicable using the
Mobility System, refer to page 208.
Run-flat tires
Maximum speed
Final tire failure
You may continue driving with a damaged tire
at speeds up to 50 mph/80 km/h.
Vibrations or loud noises while driving
can indicate the final failure of a 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.◀
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.
Intelligent Safety
3. Check the air pressure in all four tires at
the next opportunity.
The concept
Intelligent Safety enables central operation of
the driver assistance system.
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.
Depending on how the vehicle is equipped, In‐
telligent Safety consists of one or more sys‐
tems that can help prevent a imminent colli‐
sion. These systems are active automatically
every time the engine is started using the
Start/Stop button:
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on cargo load, driv‐
ing style and road conditions.

Front-end collision warning, refer to
page 117.
A vehicle with an average load has a possible
driving range of approx. 50 miles/80 km.
