Winter Driving
Here are some tips for winter driving:
0 Have your Aurora in good shape for winter.
0 You may want to put winter emergency supplies in
your trunk.
4-25
Include an ice scraper, a small brush or broom, a supply
of windshield washer fluid, a rag, some winter outer
clothing, a small shovel, a flashlight, a red cloth and a
couple of reflective warning triangles. And,
if you will
be driving under severe conditions, include a small bag
of sand, a piece of old carpet or a couple of burlap bags
to help provide traction. Be sure you properly secure
these items in your vehicle.

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.
But if you ever have to park your rig on a hill, here’s
how to do
it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet.
2. Have someone place chocks under the trailer wheels.
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
brake, and then shift to
PARK (P).
5. Release the regular brakes.

HAZARD A
The HAZARD light on the
instrument panel will
also
come on.
Your hazard flashers work no matter what position your
key
is in, and even if the key isn’t in.
To turn off the flashers, press the button down again.
When the flashers are on, your turn signals won’t work.
Other Warning Devices
If you carry reflective triangles, you can set one up at
the side
of the road about 300 feet (100 m) behind your
vehicle.
Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
Aurora. But please follow the steps below to
do it safely.
NOTICE:
Ignoring these steps could result in costly damage
to your vehicle that wouldn’t be covered by your
warranty.
Trying to
start your Aurora by pushing or
pulling it won’t work, and it could damage your
vehicle.
A CAUTION:
Batteries can hurt you. They can be dangerous
because:
They contain acid that can burn you.
0 They contain gas that can explode or ignite.
They contain enough electricity to burn
If you don’t follow these steps exactly, some or all
of these things can hurt you.

Engine Oil
OIL
If the CHECK OIL
LEVEL message or
the oil warning light on the instrument
panel comes on, it
means you need to
check your engine
oil level right away.
For more information,
see “Check Oil Level Message” or
“Oil Pressure Warning Light” in the Index. You should
check your engine
oil level regularly; this is an added
reminder.
It’s a good idea to check your engine oil every time you
get fuel. In order to get
an accurate reading, the oil must
be
warm and the vehicle must be on level ground.
Turn off the engine and give the oil a few minutes to
drain back into the oil pan.
If you don’t, the oil dipstick
might not show the actual level.
Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove
it again,
keeping the tip down, and check the level.

Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL TM (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain in your
vehicle for
5 years or 100,000 miles (1 66 000 km),
whichever occurs first.
The following explains your cooling system and how
to add coolant when
it is low. If you have a problem
with engine overheating, see “Engine Overheating” in
the Index.
A
50/50 mixture of water and the proper coolant for
your Aurora will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
NOTICE:
When adding coolant it is important that you use
DEX-COOL TM (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If
silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine
coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months whichever
occurs first.
What to Use
Use a mixture of one-half cEean, water (preferably
distilled) and one-half
DEX-COOL TM (orange-colored,
silicate-free) antifreeze that meets GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If
you use this mixture, you don’t need to add anything
else. A special procedure is required for adding sealer;
see the Aurora Service Manual.
(To order a service
manual, see “Service Publications’’ in the Index.)

your brake system fixed, since a leak means that
sooner or later your brakes won’t work well, or won’t
work at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid won’t correct a leak.
If you add fluid
when your linings are worn, then you’ll have too much
fluid when you get new brake linings. You should add
(or remove) brake fluid, as necessary, only when work is
done
on the brake hydraulic system.
I ’
A CAUTION:
When your brake fluid falls to a low level, your brake
warning light will come on. A chime will sound if you
try
to drive with this warning light on. See “Brake
System Warning Light” in the Index.
What to Add
When you do need brake fluid, use only
DOT-3 brake
fluid
-- such as Delco Supreme 11 @ (GM Part
No. 1052535). Use new brake fluid from a sealed
container only, and always clean the brake fluid
reservoir cap before removing
it.
If you have too much brake fluid, it can spill on
the engine. The fluid will burn if the engine is hot
enough.
You or others could be burned, and your
vehicle could be damaged. Add brake fluid only
when work is done on the brake hydraulic system. With the wrong kind of fluid in
your brake
system, your brakes may not work well, or they
may not even work at
all. This could cause a
crash. Always use the proper brake fluid.

Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This
applies only to vehicles sold in the United States.) The
grades are molded on the sidewalls of most passenger
car tires. The Uniform Tire Quality Grading system
does not apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires with
nominal rim diameters of
10 to 12 inches (25 to 30 cm),
or to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For example, a tire graded
150 would wear one and a half
(1 1/2) times as well on the government course as a tire
graded
100. The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences in
road characteristics and climate.
Traction - A, B, C
The traction grades, from highest to lowest, are A, B,
and C, and they represent the tire’s ability to stop on wet
pavement as measured under controlled conditions on
specified government test surfaces of asphalt and
concrete.
A tire marked C may have poor traction
performance.
Warning: The traction grade assigned to this tire is based
on braking (straightahead) traction tests and does not
include cornering (turning) traction.
Temperature - A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure.
The grade
C corresponds to a level of performance
which all passenger car tires must meet under the
6-45
