Heating
In cold weather, if the automatic mode is selected
(AUTO-PUSH knob indicator light is on), the system
will automatically direct the airflow out
of the lower
floor outlets and the temperature door will be positioned
at the full hot position. You can choose the extreme
comfort setting of
90°F (32°C) but the system will
not warm up
any faster by selecting the extreme
comfort setting.
In cold weather, the system will delay turning on the
fan to avoid blowing cold air. The length
of the delay
depends on the engine coolant temperature and the
outside temperature. The fan speed will increase as the
temperature
of the engine coolant increases. Rotating the
AUTO
FAN knob will override this delay by turning
off the automatic
fan control mode and changing the
fan speed.
t
Ventilation System
Your Aurora’s flow-through ventilation system always
allows outside air to flow through your vehicle when
it
is moving, even when the system is in the OFF position. The
direction
of the air can be controlled by adjusting or
closing the outlets in the instrument panel. Rotate the
control between the front outlets upward to open the
outlets and downward to close the outlets. Adjust the
direction
of airflow from side to side with the controls in
each outlet.

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.

Engine Overh -. hg
You will find a coolant temperature gage on your
Aurora’s instrument panel.
Your information center will
also display messages about engine overheating. See
“Coolant Temperature Gage” in the Index.
Overheated Engine Protection Operating
Mode
Should a low coolant condition exist and the message
HOT STOP ENGINE is displayed, an overheat
protection mode which alternates firing groups of four
cylinders helps prevent engine damage. This operating
mode allows your vehicle to be driven to a safe place in
an emergency; you may drive up to
50 miles (80 km).
Towing a trailer in the overheat protection mode should
be avoided.
Y
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine
to cool before attempting any repair.
The engine oil may be severely degraded. Change
the oil and reset the oil life indicator. See “Engine
Oil, When to Change” in the Index.

Your vehicle has an air bag system. Before attempting to
do your own service work, see “Servicing Your Air
Bag-Equipped Aurora” in the Index.
You should keep a record with all parts receipts and list
the mileage and the date
of any service work you
perform. See “Maintenance Record” in
the Index.
You can be injured and your vehicle could be
damaged if
you try to do service work on a
vehicle without knowing enough about
it.
Be sure you have sufficient knowledge,
experience, and the proper replacement
parts and tools before you attempt any
vehicle maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused. If you use
the wrong fasteners, parts can later break

You could be hurt.
Fuel
Use premium unleaded gasoline rated at 91 octane or
higher. At a minimum, it should meet Specifications ASTM
D4814 in the United States and CGSB 3.5-M93 in Canada.
Improved gasoline specifications have been developed by
the American Automobile Manufacturers Association
(AAMA) for better vehicle performance and engine
protection. Gasolines meeting the
AAMA specification
could provide improved driveability and emission control
system protection compared to other gasolines.
Be sure the posted octane for premium
is at least 91. If
the octane
is less than 91, you may get a heavy knocking
noise when you drive. (In an emergency, you may be
.
able to use a lower octane -- as low as 87 -- if heavy
knocking does not occur.) If you’re using
91 or higher
octane unleaded gasoline and you still hear heavy
knocking, your engine needs service.
If your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label), it
is designed to operate on fuels that meet California
specifications.
If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may turn
on and/or your vehicle
ProCarManuals.com
may fail a smog-check test. If this occurs, return to your
authorized Aurora retailer for diagnosis to determine the
cause of failure. In the event it is determined that the
cause
of the condition is the type of fuels used, repairs
may not be covered by your warranty.
Some Canadian gasolines contain an octane enhancing
additive called methlycyclopentadienyl manganese
tricarbonyl (MMT).
If such fuels are used, your
emission control system performance may be affected.
The malfunction indicator lamp on your instrument
panel may turn on.
If this occurs, return to your
authorized Aurora retailer for service.
To provide cleaner air, all gasolines are now required to
contain additives that will help prevent deposits from
forming in your engine and fuel system, allowing your
emission control system to function properly. Therefore,
you should not have to add anything to the fuel. In
addition, gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines may be
available in your area to help clean the air. General
Motors recommends that you use these gasolines if they
comply with the specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
Fuels in Foreign Countries
Lf you plan on driving in another country outside the United
States or Canada, the proper fuel may
be hard to find.
Never use leaded gasoline or any other fuel not recommended
in the previous text on fuel. Costly repairs caused by use
of improper
fuel wouldn’t be covered by your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
You can also write us at the following address for
advice. Just tell us where you’re going and give your

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.
