ECU GMC SAFARI 2005 Service Manual

Make sure the spare tire is stored securely. Push, pull,
and then try to rotate or turn the tire. If it moves,
use the ratchet/wheel wrench to tighten the cable. See
Changing a Flat Tire on page 5-72.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The rst rotation
is the most important. SeePart A: Scheduled
Maintenance Services on page 6-4.
When rotating your tires, always use the correct rotation
patterns shown here.
Do not include the compact spare tire in your tire
rotation.After the tires have been rotated, adjust the front and
rear ination pressures as shown on the Tire and
Loading Information label. SeeInation - Tire Pressure
on page 5-63andLoading Your Vehicle on page 4-27.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” underCapacities and
Specications on page 5-101.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or a
paper towel to do this; but be sure to use a
scraper or wire brush later, if you need to, to
get all the rust or dirt off. SeeChanging a Flat
Tire on page 5-72.

Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been used
or how far it’s been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel.
Tire Chains
Notice:Use tire chains only where legal and only
when you must. Use only SAE Class “S” type chains
that are the proper size for your tires. Install them
on the rear axle tires and tighten them as tightly as
possible with the ends securely fastened. Drive
slowly and follow the chain manufacturer’s
instructions. If you can hear the chains contacting
your vehicle, stop and retighten them. If the contact
continues, slow down until it stops. Driving too
fast or spinning the wheels with chains on will
damage your vehicle.

Removing the Spare Tire and Tools
The jacking equipment you’ll need is stored by your
vehicle’s rear doors, along the passenger’s side wall.
1. Remove the jack cover by pulling it away from
the side wall and down to release the tabs
securing the top of the cover.2. Remove the wheel blocks by turning the top nut
counterclockwise. Remove the nut and washer,
then pull the wheel blocks off the bolt.
3. Push down on the bolt and remove the hooked end
from the slot. Slide the jack toward the front of the
vehicle and lift it from the mounting. Remove
the extension and the ratchet from the pouch.
5-73

3. Put the at end of the extension on an angle
through the hole in the rear door frame, above
the bumper.
The compact spare is for temporary use only.
Replace the compact spare tire with a full-size tire
as soon as you can. SeeCompact Spare Tire
on page 5-84. See the storage instructions label to
restore your compact spare properly.
4. Raise the tire fully against the underside of the
vehicle by turning the ratchet/wheel wrench until
you hear two clicks or feel it skip twice. The spare
tire hoist cannot be overtightened.
5. Make sure the tire is stored securely. Push and
pull (A), and then try to turn (B) the tire. If the tire
moves, use the ratchet/wheel wrench to tighten
the cable.
6. Return the jacking equipment to its proper location.

At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety
belts replaced.
Also look for any opened or broken airbag coverings,
and have them repaired or replaced. (The airbag system
does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace
blade inserts that appear worn or damaged or that
streak or miss areas of the windshield. Also see
Windshield and Wiper Blades on page 5-90.
Spare Tire Check
At least twice a year, after the monthly ination check of
the spare tire determines that the spare is inated to
the correct tire ination pressure, make sure that
the spare tire is stored securely. Push, pull, and then try
to rotate or turn the tire. If it moves, use the wheel
wrench to tighten the cable. SeeChanging a Flat Tire
on page 5-72.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. SeePart D: Recommended Fluids and
Lubricants on page 6-30.
Automatic Transmission Check
Check the transmission uid level; add if needed. See
Automatic Transmission Fluid on page 5-24. A uid loss
may indicate a problem. Check the system and repair
if needed.
