Run-flat tires
Safety information
WARNING
Your vehicle handles differently with a
run-flat with no or low inflation pressure; for in‐
stance, your lane stability when braking is re‐
duced, braking distances are longer and the
self-steering properties will change. There is a
risk of an accident.
Drive moderately and do not exceed a speed of
50 mph/80 km/h.◀
Maximum speed
You may 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 Flat Tire Monitor may not
have been initialized. In this case, initialize
the system.
Possible driving range with a
depressurized tire
The possible driving range varies depending
on the how the vehicle is loaded and used, e.g.,
speed, road conditions, external temperature.
The driving range may be less but may also be
more if an economical driving style is used.
If the vehicle is loaded with an average weight
and used under favorable conditions, its possi‐
ble driving range will be up to 50 miles/80 km.

Vehicle handling with damaged tires
Vehicles driven with a damaged tire will handle
differently, potentially leading to conditions
such as the following:
▷ Greater likelihood of swerving off course.
▷ Longer braking distances.
▷ Changed self-steering properties.
Adjust driving style. Avoid abrupt steering ma‐
neuvers or driving over obstacles, for instance
curbs, potholes, etc.
Final tire failure
Vibrations or loud noises while driving can indi‐
cate the final failure of a tire.
Reduce speed and stop; otherwise, pieces of
the tire could come loose and cause an acci‐
dent.
Do not continue driving. Contact a dealer's
service center or another qualified service cen‐
ter or repair shop.
Intelligent Safety
Concept
Intelligent Safety enables central operation of
the driver assistance system.
Depending on how the vehicle is equipped, In‐
telligent Safety consists of one or more sys‐
tems that can help prevent an imminent colli‐
sion. These systems are active automatically
every time the engine is started using the
Start/Stop button:
▷ Approach control warning, refer to
page 131.
▷ Pedestrian warning, refer to page 137.
