Symbol Possible cause
There is a flat tire or a major loss in
tire inflation pressure.
No reset was performed for the sys‐
tem. The system issues a warning
based on the tire inflation pressures
stored during the last reset.
Measure
1. Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.
2. Check whether the vehicle is fitted with
normal tires or run-flat tires.
Run-flat tires, refer to page 214, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's sidewall.
Actions in the event of a flat tire
Normal tires
1.
Identify the damaged tire.
Check the air pressure in all four tires, for
instance using the tire pressure gage of a
tire repair kit.
If the tire inflation pressure in all four tires
is correct, the Tire Pressure Monitor may
not have been reset. In this case, perform
the reset.
If identification of flat tire damage is not
possible, please contact a dealer’s service
center or another qualified service center
or repair shop.
2.
Repair the flat tire, for instance with a tire
repair kit or by changing the tire.
Use of sealant, for instance from the tire repair
kit, may damage the TPM wheel electronics. In
this case, have the electronics checked and re‐
placed at the next opportunity.
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 Tire Pressure Monitor may
not have been reset. In this case, perform
the reset.
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.
