Windshield Wiper Blade Replacement
Replacement blades come in different types and are
removed in different ways. Here’s how
to remove the
type with a release hole:
1. Pull the windshield wiper arm away from
the windshield.
2. Insert a small screwdriver into the hole (A) and
pull the blade assembly
off the wiper arm (B).
3. Push the new wiper blade securely on the wiper arm.
For the proper windshield wiper blade length and
type, see “Normal Maintenance Replacement Parts” in
the Index.
Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service, see
your Aurora Warranty booklet
for details.
Poorly maintained and improperly used tires
are dangerous.
0 Overloading your tires can cause
overheating as a result of
too much friction.
You could have an air-out and a serious
accident. See “Loading Your Vehicle” in
the Index.
CAUTION: (Continued)

NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or tire
chain clearance to the body and chassis.
See “Changing a Flat Tire” in the Index for more
information.
Used Replacement Wheels
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 an accident. 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 front 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.

A safety belt that isn’t properly routed through
the seat cushion or is twisted won’t provide the
protection needed in a crash.
If the safety belt
hasn’t been routed through the seat cushion at
all, it won’t be there to work for the next
passenger.
The person sitting in that position
could be badly injured. After reinstalling the seat
cushion, always check to be sure that the safety
belts are properly routed and are not twisted.
1.
2.
3.
Buckle the center passenger position safety belt, and
then route the safety belts through the proper slots in
the seat cushion. Don’t let the safety belt get twisted.
Slide the rear of the cushion up and under the
seatback
so the rear locating guides hook into the
wire loops on the back frame.
With the seat cushion lowered, push rearward and
then press down on the seat cushion until the spring
locks on both ends engage.
4. Check to make sure the safety belts are properly
routed and that
no portion of any safety belt is
trapped under the seat. Also make sure the seat
cushion is secured.
Rear Compartment Fuse Blocks
Once the seat is removed,
you’ll find two
fuse panels
on the driver’s side of the
battery. Each is protected by
a plastic box with four tabs.
Pull up on all four tabs at
the same time to loosen
them and pull off the box.
Of these two panels, the cover on the passenger’s side
fuse panel has an extra plastic cap attachment. You’ll
need
to slide this out of the grooves which hold it there
before removing the rest of the box.
To replace the covers, line the four tabs up and simply
snap them back into place. The extra plastic cap
attachment slides back into place.
