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 5‑31. 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.
See Tire Pressure Monitor System
on page 6‑73and
Tire Pressure Monitor Operation on page 6‑74.
Engine Oil Life System
The engine oil life system calculates engine oil life
based on vehicle use and, on most vehicles, 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.

The vehicle must have a working electrical system,
including adequate battery power, for the OnStar
equipment to operate. There are other problems OnStar
cannot control that may prevent OnStar from providing
OnStar service at any particular time or place. Some
examples are damage to important parts of the vehicle
in a crash, hills, tall buildings, tunnels, weather or
wireless phone network congestion.

On some vehicles, the mute button can be used to dial
numbers into voice mail systems, or to dial phone
extensions. See the OnStar Owner's Guide for more
information.

To save your positions in memory, do the following:1. Adjust the driver's seat, including the seatback recliner, both outside mirrors, steering wheel, and
the throttle and brake pedals to a comfortable
position.
See Outside Power Foldaway Mirrors

Not all mirrors will have the ability to save and
recall the mirror positions.
2. Press and hold button 1 until two beeps sound.
A second seating, mirror, steering wheel position, and
throttle and brake pedal position can be programmed by
repeating the above steps and pressing button 2.
To recall the memory positions, the vehicle must be in

previously stored. You will hear a single beep. If you use the remote keyless entry transmitter to enter
your vehicle and the remote recall memory feature is
on, automatic seat, mirror, steering wheel position, and

or the safety belts!
With safety belts, you slow down as the vehicle does.
You get more time to stop. You stop over more distance,
and your strongest bones take the forces. That is why
safety belts make such good sense.
Questions and Answers About Safety
Belts
Q: Will I be trapped in the vehicle after a crash if Iam wearing a safety belt?
A: You could be—whether you are wearing a safety
belt or not. But your chance of being conscious
during and after an accident, so you can unbuckle
and get out, is muchgreater if you are belted. And
you can unbuckle a safety belt, even if you are
upside down.
Q: If my vehicle has airbags, why should I have to wear safety belts?
A: Airbags are supplemental systems only; so they
work withsafety belts —not instead of them.
Whether or not an airbag is provided, all occupants
still have to buckle up to get the most protection.
That is true not only in frontal collisions, but
especially in side and other collisions.

Doors and Locks
Door Locks
{WARNING:
Unlocked doors can be dangerous.
.Passengers, especially children, can easily
open the doors and fall out of a moving
vehicle. When a door is locked, the handle will
not open it. The chance of being thrown out of
the vehicle in a crash is increased if the doors
are not locked. So, all passengers should
wear safety belts properly and the doors
should be locked whenever the vehicle is
driven.(Continued)
WARNING: (Continued)
.Young children who get into unlocked vehicles
may be unable to get out. A child can be
overcome by extreme heat and can suffer
permanent injuries or even death from heat
stroke. Always lock the vehicle whenever
leaving it.
.Outsiders can easily enter through an
unlocked door when you slow down or stop
your vehicle. Locking your doors can help
prevent this from happening.
There are several ways to lock and unlock your vehicle.
From the outside, use the Remote Keyless Entry (RKE)
transmitter or the key in the driver's door.
From the inside, use the power door locks or manual
door locks. To lock or unlock the door with the manual
locks, push down or pull up on the manual lock knob.

Lockout Protection
This feature protects you from locking the key in the
vehicle when the key is in the ignition and a front door
is open.
If the driver's side power door lock switch is pressed
when the driver's door is open and the key is in the
ignition, all of the doors will lock and then the driver's
door will unlock.
If the passenger's side power door lock switch is
pressed when the front passenger's door is open and
the key is in the ignition, all of the doors will lock and
then the front passenger's door will unlock.
Rear Doors
You can open your doors from the inside or outside.
Your vehicle may also have a feature which prevents
children from opening the rear doors. SeeRear Door
Security Locks
on page 3‑12for more information.
Tailgate
{WARNING:
It is extremely dangerous to ride on the tailgate,
even when the vehicle is operated at low speeds.
People riding on the tailgate can easily lose
their balance and fall in response to vehicle
maneuvers. Falling from a moving vehicle may
result in serious injuries or death. Do not allow
people to ride on the tailgate. Be sure everyone in
your vehicle is in a seat and using a safety belt
properly.
On vehicles with a lock on the tailgate, use the key to
lock or unlock the tailgate.
Open the tailgate by lifting up on its handle while pulling
the tailgate toward you.
To shut the tailgate, firmly push it upward until it latches.
After you put the tailgate back up, pull it back towards
you to be sure it latches securely.

Windows
{WARNING:
Leaving children, helpless adults, or pets in a
vehicle with the windows closed is dangerous.
They can be overcome by the extreme heat and
suffer permanent injuries or even death from heat
stroke. Never leave a child, a helpless adult, or a
pet alone in a vehicle, especially with the windows
closed in warm or hot weather.
