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 SOON message being
turned on, reset the system.
To reset the Engine Oil Life System:
1. Turn the ignition to ON/RUN,
with the engine off.
2. Press the vehicle information
button until OIL LIFE
REMAINING displays.
3. Press and hold the set/reset
button until 100% is displayed.
You will hear three chimes
and the CHANGE ENGINE OIL
SOON message will go off.
4. Turn the key to LOCK/OFF.If the CHANGE ENGINE OIL SOON
message comes back on when
you start the vehicle, the engine oil
life system has not reset. Repeat
the procedure.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer’s warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your own
oil, be sure to drain all the oil from the
lter before disposal. Never dispose
of oil by putting it in the trash, pouring
it on the ground, into sewers, or into
streams or bodies of water. Recycle
it by taking it to a place that collects
used oil.
Engine Air Cleaner/Filter
When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/lter at the
MaintenanceIIintervals and replace
it at the rst oil change after each
50,000 mile (80 000 km) interval.
SeeScheduled Maintenance
on page 6-3for more information.
If you are driving in dusty/dirty
conditions, inspect the lter at each
engine oil change.
SeeEngine Compartment Overview
on page 5-10for the location of
the engine air cleaner/lter.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/lter,
remove the lter from the vehicle and
lightly shake the lter (away from
vehicle) to release loose dust and
dirt. If the lter remains caked with
dirt, a new lter is required.
5-14 Service and Appearance Care

A uid leak in the brake hydraulic
system can also cause a low uid
level. Have the brake hydraulic
system xed, since a leak means
that sooner or later the brakes will
not work well.
Do not top off the brake uid. Adding
uid does not correct a leak. If uid is
added when the linings are worn,
there will be too much uid when new
brake linings are installed. Add or
remove brake uid, as necessary,
only when work is done on the brake
hydraulic system.
{CAUTION
If too much brake uid is added, it
can spill on the engine and burn, if
the engine is hot enough. You or
others could be burned, and the
vehicle could be damaged. Add
brake uid only when work is done
on the brake hydraulic system.When the brake uid falls to a low
level, the brake warning light comes
on. SeeBrake System Warning
Light on page 3-33.
What to Add
Use only new DOT-3 brake uid
from a sealed container. See
Recommended Fluids and
Lubricants on page 6-12.
Always clean the brake uid
reservoir cap and the area around
the cap before removing it. This
helps keep dirt from entering
the reservoir.{CAUTION
With the wrong kind of uid in the
brake hydraulic system, the
brakes might not work well. This
could cause a crash. Always use
the proper brake uid.Notice:
Using the wrong uid
can badly damage brake
hydraulic system parts. For
example, just a few drops
of mineral-based oil, such
as engine oil, in the brake
hydraulic system can damage
brake hydraulic system
parts so badly that they will
have to be replaced. Do not let
someone put in the wrong
kind of uid.
If brake uid is spilled on the
vehicle’s painted surfaces, the
paint nish can be damaged. Be
careful not to spill brake uid
on the vehicle. If you do, wash it
off immediately. SeeWashing
Your Vehicle on page 5-86.

Brake Wear
This vehicle has disc brakes. Disc
brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake
pads are worn and new pads are
needed. The sound can come
and go or be heard all the time the
vehicle is moving, except when
applying the brake pedal rmly.
{CAUTION
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
an accident. When the brake wear
warning sound is heard, have the
vehicle serviced.Notice:Continuing to drive with
worn-out brake pads could
result in costly brake repair.
Some driving conditions or climates
can cause a brake squeal when
the brakes are rst applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent
brake pulsation. When tires are
rotated, inspect brake pads for wear
and evenly tighten wheel nuts in
the proper sequence to torque
specications inCapacities and
Specifications on page 5-98.
Brake linings should always be
replaced as complete axle sets.
Brake Pedal Travel
See your dealer/retailer if the brake
pedal does not return to normal
height, or if there is a rapid increase
in pedal travel. This could be a
sign that brake service might
be required.
Brake Adjustment
Every time the brakes are applied,
with or without the vehicle
moving, the brakes adjust for wear.
5-26 Service and Appearance Care

Jump Starting
If the vehicle’s battery has run
down, you may want to use another
vehicle and some jumper cables
to start your vehicle. Be sure to use
the following steps to do it safely.
{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 P (Park) or a
manual transmission in Neutral
before setting the parking brake.
If you have a four-wheel-drive
vehicle, be sure the transfer case
is not in Neutral.
Notice:If you leave the radio or
other accessories on during
the jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off
the radio and other accessories
when jump starting the vehicle.
3. Turn off the ignition on both
vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the accessory
power outlets. Turn off the radio
and all lamps that are not needed.
This will avoid sparks and help
save both batteries. And it could
save the radio!
5-28 Service and Appearance Care

4. Open the hoods and locate the
positive (+) and negative (−)
terminal locations on the other
vehicle. Your vehicle has a
remote positive (+) and a
remote negative (−) jump
starting terminal. SeeEngine
Compartment Overview on
page 5-10for more information
on the terminal locations.
{CAUTION
Using a match near a battery can
cause battery gas to explode.
People have been hurt doing this,
and some have been blinded. Use
a ashlight if you need more light.
Be sure the batteries have
enough water. You do not need to
add water to the ACDelco
®
battery (or batteries) installed in
your new vehicle. But if a battery
(Continued)
CAUTION (Continued)
has ller caps, be sure the right
amount of uid is there. If it is
low, add water to take care of that
rst. If you do not, explosive gas
could be present.
Battery uid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, ush
the place with water and get
medical help immediately.
{CAUTION
Fans or other moving engine
parts can injure you badly. Keep
your hands away from moving
parts once the engine is running.5. Check that the jumper cables do
not have loose or missing
insulation. If they do, you could
get a shock. The vehicles
could be damaged too.
Before you connect the cables,
here are some basic things you
should know. Positive (+) will go
to positive (+) or to a remote
positive (+) terminal if the vehicle
has one. Negative (−) will go to a
heavy, unpainted metal engine
part or to a remote negative (−)
terminal if the vehicle has one.
Do not connect positive (+) to
negative (−) or you will get
a short that would damage the
battery and maybe other
parts too. And do not connect
the negative (−) cable to
the negative (−) terminal on the
dead battery because this
can cause sparks.

How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level surface.
If the level is below the bottom of
the ller plug hole, you will need to
add some lubricant. Add enough
lubricant to raise the level to
the bottom of the ller plug hole.
Use care not to overtighten the plug.
What to Use
Refer to the Maintenance Schedule
to determine what kind of lubricant to
use. SeeRecommended Fluids and
Lubricants on page 6-12.Headlamp Aiming
Headlamp aim has been preset at
the factory and should need no
further adjustment.
However, if your vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to
the low-beam headlamps may be
necessary if oncoming drivers ash
their high-beam headlamps at
you (for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
you take the vehicle to your
dealer/retailer for service.
Bulb Replacement
For the proper type of replacement
bulbs, seeReplacement Bulbs
on page 5-35.
For any bulb changing procedure
not listed in this section, contact
your dealer/retailer.
High Intensity Discharge
(HID) Lighting
{CAUTION
The low beam high intensity
discharge lighting system operates
at a very high voltage. If you try
to service any of the system
components, you could be
seriously injured. Have your
dealer/retailer or a qualied
technician service them.
Your vehicle has HID headlamps.
After your vehicle’s HID headlamp
bulb has been replaced, you may
notice that the beam is a slightly
different shade than it was originally.
