The other label is the Certification label, found on the
rear edge of the driver’s door. It tells you the gross
weight capacity
of your vehicle, called the Gross
Vehicle Weight Rating (GVWR). The GVWR includes
the weight of the vehicle, all occupants, fuel and cargo.
Never exceed the GVWR for your vehicle, or the Gross
Axle Weight Rating (GAWR) for either the front of
rear axle.
And, if you
do have a heavy load, you should spread
it out. Don’t carry more than 176 lbs. (80 kg) in
your trunk.
Do not load your vehicle any heavier than
the GVWR, or either the maximum front or
rear GAWR.
If you do, parts on your vehicle
can break, or it can change the way your
vehicle handles. These could cause you to lose
control. Also, overloading can shorten the life
of your vehicle.
I NOTICE:
Your warranty does not cover parts or
components that fail because of overloading.

-- If you put things inside your vehicle -- like suitcases,
tools, packages, or anything else
-- they will go as fast
as the vehicle goes.
If you have to stop or turn quickly,
or if there
is a crash, they’ll keep going.

A CAUTION:
Things you put inside your vehicle can strike
and injure people in
a sudden stop or turn, or
in
a crash.
0 Put things in the trunk of your vehicle. In a
trunk, put them as
far forward as you can.
Try to spread the weight evenly.
inside the vehicle
so that some of them are
above the tops of the seats.
0 Don’t leave an unsecured child restraint in
your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
0 Never stack heavier things, like suitcases,
Electronic Level Control
This feature keeps the rear of your vehicle level as
the load changes. It
is automatic -- you don’t need to
adjust anything.
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. You may also damage your vehicle; the
resulting repairs would not be covered by your
warranty. Pull a trailer only if you have followed
all the steps in this section.
Ask your retailer for
advice and information about towing a trailer
with your vehicle.
Your vehicle can tow a trailer
if it is equipped with the
proper trailer 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.

Fuel
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, 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
or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your retailer before adding equipment to the outside of
your vehicle. Use premium unleaded
gasoline rated at 91 octane or
higher for best performance. You may use middle grade
or regular unleaded gasolines, but your vehicle may not
accelerate as well.
At a minimum, the gasoline
you use 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 (at
least 89 for middle grade and 87 for regular).
If the octane
is less than 87, you may get a heavy knocking noise when
you drive.
If it’s bad enough, it can damage your engine.
If you’re using fuel rated at the recommended octane
or higher and you hear heavy knocking, your engine
needs service. But don’t worry if you hear a little
pinging noise when you’re accelerating or driving up a
hill. That’s normal, and you don’t have to buy a higher
octane fuel to get rid
of pinging. It’s the heavy, constant
knock that means you have a problem.

If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
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 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 gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT); ask your service station operator whether or not his fuel
contains MMT. General Motors does not recommend the
use of such gasolines.
If fuels containing MMT are used,
spark plug life may be reduced and 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 in the United States
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.
I 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
If 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
Vehicle Identification Number
(VIN).

Filling Your Tank
,A CAUTION: I
Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don’t smoke if you’re near gasoline or refueling
your vehicle. Keep sparks, flames and smoking
materials away from gasoline.

The cap is behind a hinged door on the left side of
your vehicle.
The remote fuel door release can help keep your fuel
tank from being siphoned. Always be sure the fuel door
is closed and latched after refueling.
To open the fuel door (on
the driver's side of the
vehicle), press the button
next to the trunk release
button, to the right of the
steering column. The
ignition does not need to
be
on. The remote fuel door
release will work in all
transaxle positions. The fuel
door can
be opened
manually in case
of an
electrical power failure. To
do so, first open the trunk.
The release mechanism is
on the driver's side
of the
vehicle, at the top
of the
trunk compartment. Pull
the tab toward you to
release the
fuel door.
NOTICE:
Prying on a locked fuel filler door could damage
it. Use the remote fuel door manual release
located
in the trunk.

To remove the cap, turn it slowly to the left
(counterclockwise). The cap has a spring in it; if
you let go of the cap too soon, it will spring back
to the right.
While refueling, hang the tethered cap from the hook
on the fuel door.
If you get gasoline on yourself and then
something ignites
it, you could be badly burned.
Gasoline can spray out on you if you open the
fuel filler cap too quickly. This spray can happen
if your tank
is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait
for any “hiss” noise to stop. Then unscrew
the cap all the way.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See “Cleaning the
Outside of Your Vehicle” in the Index.
When you put the cap back
on, turn it to the right
(clockwise) until you hear a clicking sound. Make
sure you fully install
the cap. The diagnostic system
can determine if the fuel cap has been left off or
improperly installed. This would allow fuel to
evaporate into the atmosphere. See “Malfunction
Indicator Lamp”
in the Index.
