If the LOW OIL LEVEL or LOW OIL PRESSURE
message on the Driver Information Center appears
(DIC), it means you need to check your engine oil level
right away. For more information, see LOW OIL LEVEL
and LOW OIL PRESSURE underDIC Warnings and
Messages on page 3-67.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your 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 6-12for
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.
6-15

If the LOW COOLANT message does not appear on the
Driver Information Center (DIC) after two minutes, the
coolant is at the proper ll level. If a LOW COOLANT
message does appear, repeat Steps 1 through 3
then reinstall the pressure cap, or see your dealer.
Power Steering Fluid
SeeEngine Compartment
Overview on page 6-12for
reservoir location.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering uid
unless you suspect there is a leak in the system or
you hear an unusual noise. A uid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How to Check Power Steering Fluid
To check the power steering uid, do the following:
1. Turn the ignition off and let the engine compartment
cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with a
clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the uid level
on the dipstick.
The level should be at the FULL COLD mark.
If necessary, add only enough uid to bring the
level up to the mark.
What to Use
To determine what kind of uid to use, see
Recommended Fluids and Lubricants on page 7-11.
Always use the proper uid. Failure to use the proper
uid can cause leaks and damage hoses and seals.

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, 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.
Cold Ination Pressure:The amount of air pressure
in a tire, measured in pounds per square inch (psi)
or kilopascals (kPa) before a tire has built up heat from
driving. SeeInation - Tire Pressure on page 6-58.Curb Weight:This means the weight of a motor
vehicle with standard and optional equipment including
the maximum capacity of fuel, oil, and coolant, but
without passengers and cargo.
DOT Markings:A code molded into the sidewall of a
tire signifying that the tire is in compliance with the
U.S. Department of Transportation (DOT) motor vehicle
safety standards. The DOT code includes the Tire
Identication Number (TIN), an alphanumeric designator
which can also identify the tire manufacturer, production
plant, brand, and date of production.
GVWR:Gross Vehicle Weight Rating, seeLoading
Your Vehicle on page 5-33.
GAWR FRT:Gross Axle Weight Rating for the front
axle, seeLoading Your Vehicle on page 5-33.
GAWR RR:Gross Axle Weight Rating for the rear axle,
seeLoading Your Vehicle on page 5-33.
Intended Outboard Sidewall:The side of an
asymmetrical tire, that must always face outward when
mounted on a vehicle.
Kilopascal (kPa):The metric unit for air pressure.
Light Truck (LT-Metric) Tire:A tire used on light duty
trucks and some multipurpose passenger vehicles.

Recommended Fluids and
Lubricants
Fluids and lubricants identied below by name, part
number, or specication may be obtained from
your dealer.
Usage Fluid/Lubricant
Engine OilThe engine requires a special
engine oil meeting GM Standard
GM4718M. Oils meeting this
standard may be identied as
synthetic, and should also be
identied with the American
Petroleum Institute (API) Certied
for Gasoline Engines starburst
symbol. However, not all synthetic
API oils with the starburst symbol
will meet this GM standard.
You should look for and use only
an oil that meets GM Standard
GM4718M. GM Goodwrench
®oil
meets all the requirements for your
vehicle. For the proper viscosity,
seeEngine Oil on page 6-15.

A separate booklet entitledWarranty and Owner
Assistance Informationfurnished with each new vehicle
provides detailed warranty coverage information.
Courtesy Transportation is available only at participating
dealers and all program options, such as shuttle
service, may not be available at every dealer. Please
contact your dealer for specic information about

will be administered by appropriate dealer personnel.
Canadian Vehicles:For warranty repairs during
the Complete Vehicle Coverage period of the General
Motors of Canada New Vehicle Limited Warranty,
alternative transportation may be available under the
Courtesy Transportation Program. Please consult
your dealer for details.
General Motors reserves the right to unilaterally modify,

Vehicle Data Collection and Event
Data Recorders
Your vehicle, like other modern motor vehicles, has a
number of sophisticated computer systems that monitor
and control several aspects of the vehicle’s performance.
Your vehicle uses on-board vehicle computers to monitor
emission control components to optimize fuel economy,
to monitor conditions for airbag deployment and, if so
equipped, to provide anti-lock braking and to help the
driver control the vehicle in difficult driving situations.
Some information may be stored during regular
operations to facilitate repair of detected malfunctions;
other information is stored only in a crash event by
computer systems, such as those commonly called
event data recorders (EDR).
In a crash event, computer systems, such as the Airbag
Sensing and Diagnostic Module (SDM) in your vehicle
may record information about the condition of the vehicle
and how it was operated, such as data related to engine
speed, brake application, throttle position, vehicle speed,
safety belt usage, airbag readiness, airbag performance,
and the severity of a collision. If your vehicle is equipped
with StabiliTrak
®, steering performance, including yaw
rate, steering wheel angle, and lateral acceleration, is
also recorded. This information has been used to improve
vehicle crash performance and may be used to improve
crash performance of future vehicles and driving safety.
