Self supporting run flat tires
Certain models equipped with the Tire Pres-
sure Monitoring System (TPMS) can also be
equipped with self supporting run flat tires.
Tires of this type have specially reinforced
sidewalls that make it possible to continue
driving in the event of a drop in inflation pres-
sure. Tires of this type are mounted on spe-
cial rims.
NOTE
Self supporting run flat tires are only avail-
able in conjunction with TPMS.
If a self supporting run flat tire should lose
inflation pressure, the yellow TPMS warning
symbol ( ) in the instrument panel lights
up to alert the driver, and a message will be
shown in the text window in the instrument
panel.
If this occurs, reduce vehicle speed to a max-
imum of 50 mph (80 km/h). The vehicle can
be driven approximately 50 miles (80 km), or
somewhat farther if the vehicle is not heavily
loaded. The tire should be replaced as soon
as possible.
Hard braking and sudden steering maneu-
vers should be avoided.
06 Maintenance and specifications
In certain cases, it may be difficult to see
which self supporting run flat tire is defective.
To determine which tire is damaged, check
the inflation pressure of all four tires.
WARNING
• Only specially trained persons should
mount self supporting run flat tires.
• If self supporting run flat tires are mount-
ed, the vehicle must be equipped with a Tire
Pressure Monitoring System.
• After a low pressure warning has been
displayed, do not exceed 50 mph (80 km/h).
• Avoid severe cornering and hard braking,
and minimize the distance traveled before
replacing the self supporting run flat tire.
• Self supporting run flat tires cannot be re-
paired. They must be replaced if damaged
or punctured.
