RUN-FLAT or LOW TIRE PRESSURE OPERATION
SAFETY WARNING
Serious personal injury or death may result from a tire failure
or accident due to improper run-
flat or low tire pressure
operation. Read and follow the instructions below, and the
other maintenance and safety recommendations elsewhere
in this manual.
General Instructions
The Tire Pressure Monitoring System (TPMS) required in your
vehicle may have different methods of alerting you when your
tire has lost in
flation pressure. Consult your vehicle owner’s
manual for the details of your TPMS. Once the TPMS has
indicated that a tire has reduced in
flation pressure, the
run-flat mode of operation has commenced. During this
phase of operation, please follow these instructions:
•
Reduce speed as much as safely and reasonably pos-
sible; do not exceed 50 mph (80 km/h). The greater the
speed, the less distance the tire can travel.
•
Avoid abrupt or aggressive acceleration, braking, or
cornering maneuvers as much as safely and reasonably
possible. Pot holes and other road hazards should be avoid-
ed. Careful driving limits potential damage to the tire, wheel,
and vehicle.
•
Proceed to a safe and convenient location for tire ser-
vice as soon as possible. Take note of your odometer; your
operation distance is limited. See “Distance—How Far You
Can Drive,” the next section in this manual.
•
If an unusual vibration or vehicle handling difficulty
arises, stop driving as soon as safely and reasonably
possible. The tire may be about to suddenly fail. Release the
accelerator and gradually reduce speed. The tire must be
replaced before proceeding.
•
If towing a trailer, stop driving as soon as safely and
reasonably possible. In this condition, it is potentially
dangerous to operate a vehicle/trailer combination. If
possible, disconnect the trailer and proceed as noted
above. Do not continue to tow any trailer until proper tire
service or replacement has been performed.
•
Do not touch a tire recently run-low or run-flat (it may
be very hot). Allow the tire to cool before handling.
