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.
Check the air pressure in all four tires, e.g.,
using the tire pressure gage of a tire repair
kit.
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.
If identification of flat tire damage is not
possible, please contact a dealer’s service
center or another qualified service center
or repair shop.
WARNING
Your vehicle handles differently when a
run-flat tire is damaged and has low or missing
tire inflation pressure, e.g., your lane stability is
reduced when braking, braking distances are
longer and the self-steering properties will
change. There is a risk of an accident.
2. Repair the flat tire, e.g., with a tire repair kit
or by changing the tire.
Run-flat tires
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.
Final tire failure
Vibrations or loud noises while driving can indi‐
cate the final failure of a tire.
Continued driving with a flat tire
If continuing to drive with a damaged tire:
Reduce speed and stop; otherwise, pieces of
the tire could come loose and cause an acci‐
dent.
1. Avoid sudden braking and steering maneu‐
vers.
Do not continue driving. Contact a dealer’s
service center or another qualified service cen‐
ter or repair shop.
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.
Intelligent Safety
Concept
Possible driving distance with complete loss of
tire inflation pressure:
Intelligent Safety enables central operation of
the driver assistance system. Depending on
how the vehicle is equipped, Intelligent Safety
consists of one or more systems that can help
prevent an imminent collision.
The possible driving distance with a flat tire
depends on cargo load, driving style and road
conditions.

City light braking function warning, refer to

A vehicle with an average load has a possible
driving range of approx. 50 miles/80 km.
