How long should you keep the coolant heater
plugged in? The answer depends on the outside
temperature, the kind of oil you have, and
some other things. Instead of trying to list
everything here, we ask that you contact your
dealer in the area where you will be parking your
vehicle. The dealer can give you the best
advice for that particular area.
Automatic Transmission Operation
The shift lever is located on the center console
between the front seats.
There are several
different positions for
the shift lever.
PARK (P):This position locks the rear wheels. It
is the best position to use when you start the
engine because your vehicle cannot move easily.
{CAUTION:
It is dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P)
with the parking brake rmly set. Your
vehicle can roll.
Do not leave your vehicle when the engine
is running unless you have to. If you have
left the engine running, the vehicle can
move suddenly. You or others could be
injured. To be sure your vehicle will not
move, even when you are on fairly level
ground, always set your parking brake
and move the shift lever to PARK (P). See
Shifting Into Park (P) on page 129.Ifyou
are pulling a trailer, seeTowing a Trailer
on page 331.

AUTOMATIC LIGHT CONTROL OFF
This message displays when the automatic
headlamps are turned off.
AUTOMATIC LIGHT CONTROL ON
This message displays when the automatic
headlamps are turned on.
BATTERY SAVER ACTIVE
This message displays when the system detects
that the battery voltage is dropping below expected
levels. The battery saver system starts reducing
certain features of the vehicle that you may be able
to notice. At the point that the features are disabled,
this message is displayed. It means that the vehicle
is trying to save the charge in the battery.
Turn off all unnecessary accessories to allow the
battery to recharge.
The normal battery voltage range is
11.5 to 15.5 volts. You can monitor battery voltage
on the Driver Information Center (DIC) by
pressing the trip/fuel button until BATTERY
VOLTAGE is displayed.
CHANGE ENGINE OIL SOON
When this message displays, it means that service
is required for your vehicle. See your dealer.
SeeEngine Oil on page 360andScheduled
Maintenance on page 471for more information.
When you reset the CHANGE ENGINE OIL SOON
message by clearing it from the display, you still
must reset the engine oil life system separately.
For more information on resetting the engine oil life
system, seeEngine Oil Life System on page 363.
CHECK TIRE PRESSURE
If your vehicle has a Tire Pressure Monitor (TPM)
system, this message displays when the tire
pressure in one of the tires needs to be checked.
This message also displays LEFT FRONT,
RIGHT FRONT, LEFT REAR, or RIGHT REAR to
indicate which tire needs to be checked. You
can receive more than one tire pressure message
at a time. To read the other messages that
may have been sent at the same time, press the
set/reset button. If a tire pressure message
appears on the DIC, stop as soon as you can.
Have the tire pressures checked and set to those
shown on the Tire Loading Information label.

XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast-to-coast in the 48 contiguous
United States, and in Canada. Just as with FM,
tall buildings or hills can interfere with satellite
radio signals, causing the sound to fade in and out.
In addition, traveling or standing under heavy
foliage, bridges, garages, or tunnels may cause
the loss of XM™ signal for a period of time.
The radio might display NO XM SIGNAL to
indicate interference.
Cellular Phone Usage
Cellular phone usage could cause interference
with your vehicle’s radio. This interference
could occur when making or receiving phone calls,
charging the phone’s battery, or simply having
the phone on. This interference is an increased
level of static while listening to the radio. If static is
received while listening to the radio, unplug the
cellular phone and turn it off.
Care of Your CDs
Handle CDs carefully. Store them in their original
cases or other protective cases and away from
direct sunlight and dust. The CD player scans the
bottom surface of the disc. If the surface of a CD is
damaged, such as cracked, broken, or scratched,
the CD will not play properly or not at all. If the
surface of a CD is soiled, take a soft, lint free cloth
or dampen a clean, soft cloth in a mild, neutral
detergent solution mixed with water, and clean it.
Make sure the wiping process starts from the center
to the edge.
Do not touch the bottom side of a CD while
handling it; this could damage the surface. Pick up
CDs by grasping the outer edges or the edge of
the hole and the outer edge.
Care of the CD Player
Do not use CD lens cleaners for CD players
because the lens of the CD optics can become
contaminated by lubricants.

Before changing lanes, check your mirrors. Then
use your turn signal.
Just before you leave the lane, glance quickly
over your shoulder to make sure there is not
another vehicle in your blind spot.
Once you are moving on the freeway, make
certain you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your
exit, do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted.
Reduce your speed according to your
speedometer, not to your sense of motion. After
driving for any distance at higher speeds, you may
tend to think you are going slower than you
actually are.Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If
you must start when you are not fresh — such
as after a day’s work — do not plan to make too
many miles that rst part of the journey. Wear
comfortable clothing and shoes you can easily
drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it
needs service, have it done before starting out. Of
course, you will nd experienced and able
service experts in GM dealerships all across North
America. They will be ready and willing to help
if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the lenses
clean?

Engine Oil
Your vehicle may have
an oil pressure light on
the instrument cluster.
There is also an OIL PRESSURE LOW STOP
ENGINE message on the Driver Information
Center (DIC). If the light and/or message appears,
check the engine oil level right away. For more
information, see “OIL PRESSURE LOW STOP
ENGINE” underDIC Warnings and Messages on
page 220andOil Pressure Light on page 211.
You should check the engine oil level regularly;
this is an added reminder.
Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 356
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil
several minutes to drain back into the oil pan.
If you do not do this, the oil dipstick might
not show the actual level.
2. Pull out the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down,
and check the level.
360
When to Add Engine Oil
If the oil is below the cross-hatched area at the tip
of the dipstick, you need to add at least one
quart/liter of oil. But you must use the right kind.
This section explains what kind of oil to use.
For engine oil crankcase capacity, seeCapacities
and Speci cations on page 464.Notice:Do not add too much oil. If the engine
has so much oil that the oil level gets above
the cross-hatched area that shows the
proper operating range, the engine could be
damaged.
SeeEngine
Compartment Overview
on page 356for the
location of the engine
oil ll cap.
Be sure to add enough oil to put the level
somewhere in the proper operating range. Push the
dipstick all the way back in when you are through.
