Driving on Snow or Ice
Most of the time, those places where your tires meet the
road probably have good traction.
However, if there is snow or ice between your tires and the
road, you can have a very slippery situation. You’ll have a
lot less traction or “grip” and will need to be very careful.
A
What’s the worst time for this? “Wet ice.” Very cold snow
or ice can be slick and hard
to drive on. But wet ice can be
even more trouble because it may offer the least traction of all.
You can get wet ice when
it’s about freezing
(32 OF; 0 “C) and freezing rain begins to fall. Try to avoid
driving on wet ice until salt and sand crews can get there.
Whatever the condition
-- smooth ice, packed, blowing
or loose snow
-- drive with caution.
Keep your traction control system on. It improves your
ability to accelerate when driving on a slippery road. Even
though your vehicle has a traction control system, you’ll
want to slow down and adjust your driving to the road
conditions. See “Traction Control System” in the Index.
Your anti-lock brakes improve your vehicle’s stability
when you make a hard stop on a slippery road. Even
though you have the anti-lock braking system, you’ll
want to begin stopping sooner than you would
on dry
pavement. See “Anti-Lock”
in the Index.
Allow greater following distance on any slippery road.
Watch for slippery spots. The road might be fine until
you hit a spot that’s covered with ice. On
an otherwise
clear road, ice patches may appear
in shaded areas
where the sun can’t reach: around clumps
of trees,
behind buildings or under bridges. Sometimes the
surface
of a curve or an overpass may remain icy when
the surrounding roads are clear.
If you see a patch of
ice ahead
of you, brake before you are on it. Try not to
brake while you’re actually on the ice, and avoid
sudden steering maneuvers.

Towing a Trailer
,A CAUTION:
If you don’t use the correct equipment and drive
properly, you can lose control when you pull
a
trailer. For example, if the trailer is too heavy, the
brakes may not work well
-- or even at all. You
and your passengers could be seriously injured.
Pull
a trailer only if you have followed all the
steps in this section. Ask your Aurora retailer for
advice and information about towing
a trailer
with your vehicle.
NOTICE:
Pulling a trailer improperly can damage your
vehicle
and result in costly repairs not covered by
your warranty. To pull a trailer correctly, follow
the advice in this part, and see your Aurora
retailer for important information about towing
a trailer with your vehicle.
Your vehicle can tow a trailer if it is equipped with
proper towing equipment.
To identify what the vehicle
trailering capacity is for your vehicle, you should read
the information in “Weight
of the Trailer” that appears
later in this section. But trailering is different than just
driving your vehicle by itself. Trailering means changes
in handling, durability and fuel economy. Successful,
safe trailering takes correct equipment, and it has
to be
used properly.

Trailer Brakes
Does your trailer have its own brakes?
Be sure to read and follow the instructions for the trailer
brakes
so you’ll be able to install, adjust and maintain
them properly.
Because you have anti-lock brakes, do not try
to tap into
your vehicle’s brake system. If you do, both brake
systems won’t work well, or at all.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand
to be sure
the brakes are working. This lets
you check your
electrical connection at the same time. During your trip, check occasionally
to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help you avoid situations that require heavy braking
and sudden turns.
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal
longer, you’ll need to go much farther beyond the
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steenng wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up slowly and, if
possible, have someone guide you.
4-36

Making Turns
I NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns than
normal.
Do this so your trailer won’t strike soft shoulders,
curbs, road signs,
trees or other objects. Avoid jerky or
sudden maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
The green arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you’re about to turn, change lanes or stop.
When towing a trailer, the green arrows
on your
instrument panel will flash for turns even
if the bulbs on
the trailer are burned out. Thus, you may think drivers
behind you
are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working. Your
vehicle may have bulb warning messages. When
you plug a trailer lighting system into your vehicle’s
lighting system, its bulb warning messages may not let
you know
if one of your lamps goes out. So, when you
have a trailer lighting system plugged in, be sure to
check your vehicle and trailer lamps from time
to time
to be sure they’re all working. Once you disconnect the
trailer lamps, the bulb warning messages again can tell
you if one
of your vehicle lamps is out.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade.
If you don’t shift
down, you might have
to use your brakes so much that
they would get hot and no longer work well.
Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
4-37

But if you ever have to park your rig on a hill, here’s
how to do it:
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking
5. Release the regular brakes.
brake,
and then shift to PARK
(P).
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
0 Start your engine;
0 Shift into a gear; and
0 Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system and brake adjustment.
Each
of these is covered in this manual, and the Index
will help you
find them quickly. If you’re trailering, it’s
a good idea
to review these sections before you start
your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
4-38

2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other.
If they are, it could cause a ground
connection you don’t want. You wouldn’t be able to
start your Aurora, and the bad grounding could
damage the electrical systems.
To avoid the possibility
of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. Put an automatic transaxle
in
PARK (P) before setting the parking brake.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory power outlet.
Turn off all lamps
that aren’t needed as well as radios. This will avoid
sparks and help save both batteries. In addition, it
could save your radio.
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
4. Open the hoods and locate the other vehicle’s battery
and the Aurora’s remote positive
(+) jump starting
terminal in the box on the passenger side
of the
engine compartment.
(Your Aurora’s battery isn’t
under the hood.)
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tsols away from any underhood
electric fan.

A vehicle can fall from a car carrier if it isn’t
adequately secured. This can cause
a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains or
steel cables before it is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath the towed vehicle. Always use
T-hooks inserted in the T-hook slots. Never use
J-hooks. They will damage drivetrain and
suspension components. When
your vehicle
is being towed, have the ignition key
turned to
OFF. The steering wheel should be clamped in
a straight-ahead position, with a clamping device
designed for towing service. Do not use the vehicle’s
steering column lock for this. The transaxle should be in
NEUTRAL (N) and the parking brake released.
Don’t have your vehicle towed on the drive wheels, unless you must.
If the vehicle must be towed on the
drive wheels, be sure to follow the speed and distance
restrictions later in this section or your transaxle will be
damaged.
If these limitations must be exceeded, then the
drive wheels have
to be supported on a dolly.

5. Then replace the pressure cap. Be sure the pressure
cap is tight.
If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have a “blowout,” here are a
few tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off
the accelerator pedal and grip the steering wheel firmly.
Steer
to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely.
5-23

Ckanging a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
Changing
a tire can cause an injury. The vehicle
can slip
off the jack and roll over you or other
people. You and they could be badly injured.
Find
a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won't move,
you can put blocks
at the front and rear of the
tire farthest
away from the one being changed.
That would be the tire on the other side of the
vehicle, at the opposite end.

11. Using the wheel
wrench, tighten the
wheel nuts firmly in
a crisscross sequence
as shown.
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become loose
and even come
off. This could lead to an accident.
Be sure to use the correct wheel nuts.
If you have
to replace them, be sure to get new
GM original
equipment wheel nuts.
Stop somewhere
as soon as you can and have the
nuts tightened with
a torque wrench to 100 Ib-ft
(140 N-m).
NOTICE:
Improperly tightened wheel nuts can lead to
brake pulsation and rotor damage.
To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper torque specification.
12. Then replace the wheel cover. Be sure to position
the alignment pin
on the cover with the notch in the
wheel. Apply pressure around the edge
of the cap to
snap it in place.
Don’t try
to put the wheel cover on the compact
spare tire. It won’t
fit. Store the wheel cover in the
trunk until you have replaced the compact spare tire
with a regular tire.
I NOTICE:
Wheel covers won’t fit on your compact spare. If
you try to put a wheel cover on your compact
spare,
you could damage the cover or the spare.
