AVG (Average) SPD (Speed)
Press the trip/fuel button until AVG (Average) SPD
(Speed) displays. This display shows the average speed
of the vehicle in miles per hour (mph) or kilometers
per hour (km/h). This average is calculated based on
the various vehicle speeds recorded since the last reset
of this value. To reset the value, press and hold the
set/reset button. The display will return to zero.
AVG (Average) ECON (Economy)
Press the trip/fuel button until AVG (Average)
ECON (Economy) displays. This display shows the
approximate average miles per gallon (mpg) or liters per
100 kilometers (L/100 km). This number is calculated
based on the number of mpg (L/100 km) recorded
since the last time this menu item was reset. To reset
this display, press and hold the set/reset button.
The display will return to zero.
RANGE
Press the trip/fuel button until RANGE displays. This
display shows the approximate number of remaining
miles (mi) or kilometers (km) the vehicle can be
driven without refueling.
The fuel range estimate is based on an average of
the vehicle’s fuel economy over recent driving history
and the amount of fuel remaining in the fuel tank.
This estimate will change if driving conditions change.
For example, if driving in traffic and making frequentstops, this display may read one number, but if the
vehicle is driven on a freeway, the number may change
even though the same amount of fuel is in the fuel
tank. This is because different driving conditions produce
different fuel economies. Generally, freeway driving
produces better fuel economy than city driving.
If your vehicle is low on fuel, the FUEL LEVEL LOW
message will be displayed. See “FUEL LEVEL
LOW” underDIC Warnings and Messages on page 3-49
for more information.

Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having it
serviced by your dealer/retailer before departing.
Things to check on your own include:
Windshield Washer Fluid:Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All levels checked?
Lamps:Do they all work and are lenses clean?
Tires:Are treads good? Are tires in ated to
recommended pressure?
Weather and Maps:Safe to travel? Have
up-to-date maps?
Highway Hypnosis
Always be alert and pay attention to your surroundings
while driving. If you become tired or sleepy, nd a safe
place to park your vehicle and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan the road ahead
and to the sides.
Check the rearview mirror and vehicle instruments
often.
Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on at or rolling terrain. Tips for driving
in these conditions include:
Keep your vehicle serviced and in good shape.
Check all uid levels and brakes, tires, cooling
system, and transmission.
Going down steep or long hills, shift to a
lower gear.
{CAUTION:
If you do not shift down, the brakes could get
so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Shift down
to let the engine assist the brakes on a steep
downhill slope.

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. See
Engine Compartment Overview on page 5-12for
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.
5-15

When to Add Engine Oil
If the oil is below the cross-hatched area at the tip of
the dipstick, add at least one quart/liter of the
recommended oil. This section explains what kind of oil to
use. For engine oil crankcase capacity, seeCapacities
and Specifications on page 5-107.
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 5-12for
the location of the engine
oil ll cap.
Be sure to add enough oil to put the level somewhere in
the proper operating range in the cross-hatched area.
Push the dipstick all the way back in when you are
through.SAE 5W-30 may not
appear on all caps.

Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet
GM Standard GM6094M are all you need for
good performance and engine protection.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer system that lets you know
when to change the engine oil and lter. This is based
on engine revolutions and engine temperature, and not
on mileage. Based on driving conditions, the mileage at
which an oil change will be indicated can vary
considerably. For the oil life system to work properly, you
must reset the system every time the oil is changed.
When the system has calculated that oil life has
been diminished, it will indicate that an oil change is
necessary. A change engine oil light and a CHANGE
ENGINE OIL SOON message will come on. Change
the oil as soon as possible within the next 600 miles
(1 000 km). It is possible that, if you are driving under
the best conditions, the oil life system might not indicate
that an oil change is necessary for over a year. However,
the engine oil and lter must be changed at least
once a year and at this time the system must be reset.Your dealer/retailer has trained service people who will
perform this work using genuine parts and reset the
system. It is also important to check the oil regularly and
keep it at the proper level.
If the system is ever reset accidentally, you must
change the oil at 3,000 miles (5 000 km) since the last
oil change. Remember to reset the oil life system
whenever the oil is changed.
How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to change
the engine oil and lter based on vehicle use. Whenever
the oil is changed, reset the system so it can calculate
when the next oil change is required. If a situation occurs
where you change the oil prior to a change engine oil light
or CHANGE ENGINE OIL SOON message being turned
on, reset the system.
1. Turn the ignition key to ON/RUN with the
engine off.
2. Fully press and release the accelerator pedal three
times within ve seconds.
The change engine oil light will ash while the
system is resetting.
3. When the light stops ashing, turn the key to
LOCK/OFF.

{CAUTION:
An electric engine cooling fan under the hood
can start up even when the engine is not
running and can injure you. Keep hands,
clothing, and tools away from any underhood
electric fan.
If the coolant inside the coolant surge tank is boiling, do
not do anything else until it cools down. The vehicle
should be parked on a level surface.
The coolant level should be at the COLD FILL line. If it
is not, you may have a leak at the radiator hoses,
heater hoses, radiator, water pump, or somewhere else in
the cooling system.
{CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them. If
you do, you can be burned.
CAUTION: (Continued)
CAUTION: (Continued)
Do not run the engine if there is a leak. If
you run the engine, it could lose all
coolant. That could cause an engine re,
and you could be burned. Get any leak
xed before you drive
the vehicle.
If there seems to be no leak, with the engine on, check
to see if the electric engine cooling fans are running.
If the engine is overheating, both fans should be
running. If they are not, your vehicle needs service.
Turn off the engine.
Notice:Engine damage from running your engine
without coolant is not covered by your warranty. See
Overheated Engine Protection Operating Mode on
page 5-26for information on driving to a safe place in
an emergency.
Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant could
require changing sooner, at 30,000 miles (50 000 km)
or 24 months, whichever occurs rst. Any repairs
would not be covered by the warranty. Always use
DEX-COOL
®(silicate-free) coolant in the vehicle.

Maintenance Schedule
Introduction
Important: Keep engine oil at the proper level and
change as recommended.
Have you purchased the GM Protection Plan? The Plan
supplements your new vehicle warranties. See your
Warranty and Owner Assistance booklet or your
dealer/retailer for details.
Maintenance Requirements
Notice:Maintenance intervals, checks, inspections,
replacement parts, and recommended uids and
lubricants as prescribed in this manual are
necessary to keep your vehicle in good working
condition. Any damage caused by failure to follow
scheduled maintenance might not be covered by
warranty.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. All recommended maintenance is
important. Improper vehicle maintenance can even affect
the quality of the air we breathe. Improper uid levels or
the wrong tire in ation can increase the level of emissions
from your vehicle. To help protect our environment, and
to keep your vehicle in good condition, be sure to
maintain your vehicle properly.
Using the Maintenance Schedule
We want to help you keep your vehicle in good working
condition. But we do not know exactly how you will
drive it. You might drive very short distances only a few
times a week. Or you might drive long distances all the
time in very hot, dusty weather. You might use your
vehicle in making deliveries. Or you might drive it to work,
to do errands, or in many other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You might need more
frequent checks and replacements. So please read the
following and note how you drive. If you have any
questions on how to keep your vehicle in good condition,
see your dealer/retailer.
