Headlamps on Reminder
A warning chime will sound if the exterior lamp
control is left on in either the headlamp or parking
lamp position and the driver’s door is opened
with the ignition off. SeeLights On Reminder on
page 256for additional information.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during
the day. DRL can be helpful in many different
driving conditions, but they can be especially
helpful in the short periods after dawn and before
sunset. Fully functional daytime running lamps
are required on all vehicles rst sold in Canada.
The DRL system will make the turn signal lamps
come on when the following conditions are met:
It is still daylight and the ignition is on,
the automatic lights are enabled, and
the transmission is not in PARK (P).
When DRL are on, only your front turn signal
lamps will be on. No other exterior lamps will be
on when the DRL are being used. Your instrument
panel will not be lit.When the automatic lights are enabled and it is dark
enough outside, the DRL will turn off and the
low-beam headlamps will turn on. When it is bright
enough outside, the low-beam headlamps will go
off, and the DRL will turn back on. If you start your
vehicle in a dark garage, the automatic headlamp
system will come on immediately. Once you leave
the garage, it will take about one minute for the
automatic headlamp system to change to DRL if it
is light outside. During that delay, your instrument
panel cluster may not be as bright as usual. Make
sure your instrument panel brightness lever is in the
full bright position. SeeInstrument Panel Brightness
on page 220.
To operate your vehicle with the DRL off, turn the
exterior lamp control off and then do one of the
following:
Turn the exterior lamp control to the parking
lamp position.
Turn the exterior lamp control to the headlamp
position.
Turn the exterior lamp control from AUTO to
off and back to AUTO.

Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high
in your eld of view, it may take you more
time to see things you need to see when it
is dark outside. Be sure to keep the HUD
image dim and placed low in your eld
of view.
If equipped, the Head-Up Display (HUD) allows
you to see some of the driver information that
appears on your instrument panel cluster on the
windshield.
The information may be displayed in English or
metric units and appears as an image focused out
toward the front of your vehicle. To change
from English to metric units, seeDIC Controls and
Displays on page 258.
The HUD consists of the following information:

Driver Information Center (DIC)
The Driver Information Center (DIC) gives you the
status of many of your vehicle’s systems. The DIC
is also used to display warning/status messages.
All messages will appear in the DIC display located
at the bottom of the instrument panel cluster, below
the tachometer and speedometer. The DIC buttons
are located on the instrument panel, to the left of
the steering wheel.
The DIC comes on when the ignition is on. After a
short delay, the DIC will display the current
driver and the information that was last displayed
before the engine was turned off.
The top line of the DIC display shows the vehicle
system information and the warning/status
messages. The bottom line of the DIC display
shows either the odometer, the trip odometer A or
the trip odometer B information on the left side.
Only one odometer can appear at a time. See “Trip
Information” underDIC Controls and Displays
on page 258for information on changing the
display to show the odometer or trip odometer
information. The bottom line of the DIC display
also shows the outside temperature on the
right side and the shift lever position indicator inthe center. SeeAutomatic Transmission Operation
on page 116for more information on the shift
lever positions.
When the sport mode is active, an S will appear
next to the shift position indicator on the center of
the DIC display. When the manual mode is
active, an M will appear on the DIC display. When
the normal mode is active, only the shift position
indicator will appear. While the Driver Shift
Control (DSC) feature is active, the DIC will
change to show the selected gear. See “Driver
Shift Control (DSC)” underAutomatic Transmission
Operation on page 116for more information.
If a problem is detected, a warning message will
appear on the display. Be sure to take any
message that appears on the display seriously and
remember that clearing the message will only make
the message disappear, not correct the problem.
DIC Controls and Displays
The Driver Information Center (DIC) has different
modes which can be accessed by pressing
the four DIC buttons located on the instrument
panel, to the left of the steering wheel.

The traction you can get in a curve depends on
the condition of your tires and the road surface, the
angle at which the curve is banked, and your
speed. While you are in a curve, speed is the
one factor you can control.
Suppose you are steering through a sharp curve.
Then you suddenly accelerate. Both control
systems — steering and acceleration — have to
do their work where the tires meet the road.
Adding the sudden acceleration can demand too
much of those places. You can lose control.
SeeTraction Control System (TCS) on page 323
andStabiliTrak
®System on page 326.
What should you do if this ever happens? Ease up
on the accelerator pedal, steer the vehicle the
way you want it to go, and slow down.
Since your vehicle is equipped with StabiliTrak
®,
the system may be active. SeeDIC Warnings and
Messages on page 264andStabiliTrak
®System
on page 326.
Speed limit signs near curves warn that you
should adjust your speed. Of course, the posted
speeds are based on good weather and road
conditions. Under less favorable conditions you will
want to go slower.If you need to reduce your speed as you approach
a curve, do it before you enter the curve, while
your front wheels are straight ahead.
Try to adjust your speed so you can “drive”
through the curve. Maintain a reasonable, steady
speed. Wait to accelerate until you are out of
the curve, and then accelerate gently into
the straightaway.
To help you steer in the direction you want to go,
during certain sharp or sudden cornering
maneuvers, gear selection is controlled. This will
maximize the available drive wheel torque and
minimize the transmission response time and shift
activity. During this kind of maneuver, the
transmission shifts automatically as vehicle
speed changes.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 363.

Automatic Transmission Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check the transmission uid
level. A transmission uid leak is the only
reason for uid loss. If a leak occurs, take the
vehicle to the dealership service department and
have it repaired as soon as possible.
There is a special procedure for checking and
changing the transmission uid. Because
this procedure is difficult, you should have this
done at the dealership service department.Contact your dealer for additional information or
the procedure can be found in the service manual.
To purchase a service manual, seeService
Publications Ordering Information on page 543.
Notice:Use of the incorrect automatic
transmission uid may damage your vehicle,
and the damages may not be covered by
your warranty. Always use the automatic
transmission uid listed inRecommended
Fluids and Lubricants on page 516.
Change the uid and lter at the intervals listed in
Additional Required Services on page 508, and
be sure to use the uid listed inRecommended
Fluids and Lubricants on page 516.

{CAUTION:
Batteries can hurt you. They can be
dangerous because:
They contain acid that can burn you.
They contain gas that can explode
or ignite.
They contain enough electricity to
burn you.
If you do not follow these steps exactly,
some or all of these things can hurt you.
Notice:Ignoring these steps could result in
costly damage to your vehicle that would
not be covered by your warranty.
Trying to start your vehicle by pushing or
pulling it will not work, and it could damage
your vehicle.
1. Check the other vehicle. It must have a
12-volt battery with a negative ground system.Notice:If the other vehicle’s system is not a
12-volt system with a negative ground,
both vehicles can be damaged. Only use
vehicles with 12-volt systems with negative
grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper
cables can reach, but be sure the vehicles are
not touching each other. If they are, it could
cause a ground connection you do not
want. You would not be able to start your
vehicle and the bad grounding could damage
the electrical systems.
To avoid the possibility of the vehicles rolling,
set the parking brake rmly on both vehicles
involved in the jump start procedure. Put
an automatic transmission in PARK (P) or a
manual transmission in NEUTRAL before
setting the parking brake.

(C) Aspect Ratio:A two-digit number that
indicates the tire height-to-width measurements.
For example, if the tire size aspect ratio is
60, as shown in item C of the illustration, it would
mean that the tire’s sidewall is 60 percent as
high as it is wide.
(D) Construction Code:A letter code is used to
indicate the type of ply construction in the tire.
The letter R means radial ply construction;
the letter D means diagonal or bias ply
construction; and the letter B means belted-bias
ply construction.
(E) Rim Diameter:Diameter of the wheel
in inches.
(F) Service Description:These characters
represent the load range and speed rating of the
tire. The load index represents the load carry
capacity a tire is certied to carry. The load index
can range from 1 to 279. The speed rating is
the maximum speed a tire is certied to carry a
load. Speed ratings range from A to Z.Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire
pressing outward on each square inch of the
tire. Air pressure is expressed in pounds
per square inch (psi) or kilopascal (kPa).
Accessory Weight:This means the combined
weight of optional accessories. Some examples of
optional accessories are, automatic
transmission/transaxle, power steering, power
brakes, power windows, power seats, and
air conditioning.
Aspect Ratio:The relationship of a tire’s height
to its width.
Belt:A rubber coated layer of cords that is
located between the plies and the tread. Cords
may be made from steel or other reinforcing
materials.
Bead:The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.
Bias Ply Tire:A pneumatic tire in which the plies
are laid at alternate angles less than 90 degrees
to the centerline of the tread.
