Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have
the headlamp wiring checked right
away if the lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice, may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using
the windshield wipers.
If the overload is caused by an
electrical problem and not snow
or ice, be sure to get it fixed.
Fuses and Circuit
Breakers
The wiring circuits in the vehicle
are protected from short circuits by
a combination of fuses and circuit
breakers. This greatly reduces the
chance of damage caused by
electrical problems.
To check a fuse, look at the
silver-colored band inside the fuse.
If the band is broken or melted,
replace the fuse. Be sure to replace
a bad fuse with a new one of the
identical size and rating.
Fuses of the same amperage
can be temporarily borrowed from
another fuse location, if a fuse goes
out. Replace the fuse as soon as
possible.
To identify and check fuses, circuit
breakers, and relays, seeEngine
Compartment Fuse Block on
page 9-42,Instrument Panel Fuse
Block on page 9-45, andRear
Compartment Fuse Block on
page 9-46.
Engine Compartment
Fuse Block
To remove the hinged fuse block
cover, press the clip at the front of
the cover, and swing it up.
Notice:Spilling liquid on any
electrical components on the
vehicle may damage it. Always
keep the covers on any electrical
component.
9-42 Vehicle Care
The positive jump start connection
is covered by a red cap. Remove to
expose the terminal.
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. Position the two vehicles so that
they are not touching.
3. Set the parking brake firmly and
put the shift lever in P (Park).
SeeShifting Into Park on
page 8-21.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.
4. Turn the ignition to LOCK/OFF
and switch off all lights and
accessories in both vehicles,
except the hazard warning
flashers if needed.
{WARNING
An electric fan 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.
{WARNING
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 flashlight if you need more light.
Be sure the battery has enough
water. You do not need to add
water to the battery installed in
your new vehicle. But if a battery
has filler caps, be sure the right
amount of fluid is there. If it is
low, add water to take care of
that first. If you don’t, explosive
gas could be present.
Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, flush
the place with water and get
medical help immediately.
Vehicle Care 9-85
At your General Motors dealer/
retailer, you can be certain that
you will receive the highest level
of service available. Your dealer
/retailer has specially trained service
technicians, uses genuine GM
replacement parts, as well as, up to
date tools and equipment to ensure
fast and accurate diagnostics.
The proper replacement parts,
fluids, and lubricants to use are
listed inRecommended Fluids
and Lubricants on page 10-7and
Maintenance Replacement Parts on
page 10-9. We recommend the use
of genuine parts from your dealer/
retailer.
Rotation of New Tires
Tire rotation is not recommended if
the vehicle has different size tires
on the front and rear wheels. If tire
rotation is recommended for the
vehicle, to maintain ride, handling,
and performance of the vehicle,
it is important that the first rotation
service for new tires be performed
when they have 8 000 to 13 000 km
(5,000 to 8,000 miles). SeeTire
Rotation on page 9-61.Scheduled

When the Change Engine Oil
Soon message displays, service is
required for the vehicle as soon as
possible, within the next 1 000 km/
600 miles. If driving under the best
conditions, the engine oil life system
might not indicate the need for
vehicle service for more than a year.
The engine oil and filter must be
changed at least once a year and the
oil life system must be reset. Your
dealer/retailer has trained service
technicians who will perform this
work and reset the system.If the engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 miles since
the last service. Reset the oil life
system whenever the oil is changed.
SeeEngine Oil Life System on
page 9-13.
When the Change Engine Oil
Soon message displays, certain
services, checks, and inspections
are required. The services described
for MaintenanceIshould be
performed at every engine oil
change. The services described
for MaintenanceIIshould be
performed when:
•MaintenanceIwas performed
the last time the engine oil was
changed.
•It has been 10 months or more
since the Change Engine Oil
