Warning!
Each tire, including the spare (if provided),
should be checked every other week when
cold and inflated to the inflation pressure
recommended by the vehicle manufacturer
on the Tire and Loading Information placard
on the driver’s door B-pillar or, if available, the
tire inflation pressure label on the inside of
the fuel filler flap. If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or the tire inflation pressure
label, you should determine the proper tire
inflation pressure for those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires are significantly underinflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly underinflated tire causes the tire
to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle’s
