Tire Pressure Monitor
This vehicle may have a Tire Pressure Monitor
System (TPMS).
The Tire Pressure Monitor
alerts you when a
significant reduction in
pressure occurs in one or
more of the vehicle’s tires
by illuminating the low tire
pressure warning light on
the instrument cluster.
The warning light will remain on until the tire pressure is
corrected. The proper tire pressures for your vehicle
are listed on the Tire and Loading Information label
located on the driver side center pillar (B pillar). See
Loading the Vehicle on page 5-19.
You may notice during cooler conditions that the low tire
pressure warning light will appear when the vehicle is
first started and then turn off as you drive. This may be
an early indicator that your tire pressures are getting
low and the tires need to be inflated to the proper
pressure.Note:The Tire Pressure Monitor can alert you about
low tire pressure, but it does not replace normal monthly
tire maintenance. It is the driver’s responsibility to
maintain correct tire pressures.
SeeTire Pressure Monitor System on page 6-70and
Tire Pressure Monitor Operation on page 6-72.
Engine Oil Life System
The engine oil life system calculates engine oil life
based on vehicle use and displays a DIC message when
it is necessary 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.
3. Turn the key to LOCK/OFF.

Tire Pressure Light
For vehicles with a tire
pressure monitoring
system, this light comes
on briefly when the engine
is started. It provides
information about tire
pressures and the Tire
Pressure Monitoring
System.
When the Light is On Steady
This indicates that one or more of the tires are
significantly underinflated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDriver
Information Center (DIC) on page 4-36for more
information. Stop and check the tires as soon as it is
safe to do so. If underinflated, inflate to the proper
pressure. SeeInation - Tire Pressure on page 6-68
for more information.
When the Light Flashes First and Then is
On Steady
This indicates that there may be a problem with the Tire
Pressure Monitor System. The light flashes for about
a minute and stays on steady for the remainder of
the ignition cycle. This sequence repeats with every
ignition cycle. SeeTire Pressure Monitor Operation on
page 6-72for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It ensures that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment.
This light should come on
when the ignition is on, but
the engine is not running,
as a check to show it
is working. If it does not,
have the vehicle serviced
by your dealer/retailer.
