1-22 In Brief
Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS warning light alerts you
to a significant loss in pressure of
one of the vehicle's tires. If the
warning light comes on, stop as
soon as possible and inflate the
tires to the recommended pressure
shown on the Tire and Loading
Information label. See Vehicle Load
Limits on page 9 11. The warning
light will remain on until the tire
pressure is corrected.
During cooler conditions, the low tire
pressure warning light may appear
when the vehicle is first started and
then turn off. This may be an early
indicator that the tire pressures are
getting low and the tires need to be
inflated to the proper pressure.
The TPMS does not replace normal
monthly tire maintenance. It is the
driver s responsibility to maintain
correct tire pressures.
See Tire Pressure Monitor System
on page 10 76.
Tire Sealant and
Compressor Kit
This vehicle may come with a jack
and spare tire or a tire sealant and
compressor kit. The kit can be used
to seal small punctures in the tread
area of the tire.
See Tire Sealant and Compressor
Kit on page 10 92 for complete
operating information.
If the vehicle came with a jack and
spare tire, see If a Tire Goes Flat on
page 10 90.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays the Change Engine
Oil Soon message when it is time
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change.
Resetting the Oil Life System
1. Turn the ignition to ON/RUN with
the engine off.
2. Fully press and release the
accelerator pedal three times
within five seconds.
See Engine Oil Life System on
page 10 14.
