The CertificatiodTire label is found on the driver’s door
edge, above the door latch. The label shows the size of
your original tires and the inflation pressures needed
to
obtain the gross weight capacity of your vehicle. This is
called the GVWR (Gross Vehicle Weight Rating). The
GVWR includes the weight of the vehicle, all occupants,
fuel, cargo and trailer tongue weight, if pulling a trailer.
The CertificatiodTire label also tells you the maximum
weights for the front and rear axles, called Gross Axle
Weight Rating (GAWR). To find out the actual loads on
your front and rear axles, you need to go to a weigh
station and weigh your vehicle. Your retailer can help
you with this. Be sure to spread out your load equally on
both sides of the centerline. Never exceed
the GVWR for your vehicle, or the Gross
Axle Weight Rating (GAWR) for either the front or
rear axle.
If you do have a heavy load, you should spread it out.
Similar appearing vehicles may have different GVWR’s
and payloads. Please note your vehicle’s
Certificatioflire label or consult your retailer for
additional details.
I A CAUTION:
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.

Using heavier suspension components to get added
durability might not change your weight ratings. Ask
your retailer to help you load your vehicle the right way.

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. Things
you put inside your vehicle can strike
and injure people in a sudden stop or turn, or in
a crash.
Put things in the cargo area of your vehicle.
Never stack heavier things, like suitcases, Try to spread the weight evenly.
inside the vehicle
so that some of them are
above the tops of the seats.
Don’t leave an unsecured child restraint in
your vehicle.
When you carry something inside the
vehicle, secure it whenever
you can.
Don’t leave a seat folded down unless you
need to.
There’s also important loading information
for off-road
driving in this manual. See “Loading Your Vehicle” in
the Index.

Payload
The payload capacity is shown on the CertificatiodTire
label. This
is the maximum load capacity that your
vehicle can carry. Be sure to include the weight of the
occupants as part
of your load. If you added any
accessories or equipment after your vehicle
left the
factory, remember to subtract the weight
of these things
from the payload. Your retailer can help you with this.
Add-on Equipment
When you carry removable items, you may need to put a
limit on how many people
you carry inside your vehicle.
Be sure to weigh your vehicle before you buy and install
the new equipment.
Your warranty doesn’t cover parts or
components that fail because of overloading.
Towing a Trailer
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 Oldsmobile retailer
for advice and information about towing a trailer with your vehicle.
ProCarManuals.com

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 Oldsmobile
retailer
for important information about towing
a trailer with your vehicle.
Every Bravada is ready for some trailer towing. If yours
was built with trailering options, as many are, it’s ready
for heavier trailers. 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.
That’s the reason for this part. In it are many
time-tested, important trailering tips and safety rules.
Many of these are important for your safety and that of
your passengers.
So please read this section carefully
before you pull a trailer.
If You Do Decide To Pull A Trailer

There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your rig will be legal, not
only where you live but
also where you’ll be driving.
A good source for this
information can be state or provincial police.
Consider using
a sway control if your trailer will
weigh
2,000 Ibs. (900 kg) or less. You should always
use
a sway control if your trailer will weigh more
than
2,000 lbs. (900 kg). You can ask a hitch dealer
about sway controls.
Don’t
tow a trailer at all during the first 500 miles
(800 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
Then, during the first
500 miles (800 km) that you
tow
a trailer, don’t drive over 50 mph (80 Mh) and
don’t make starts at
full throttle. This helps your
engine and other parts of your vehicle wear in at the
heavier loads.
You should use THIRD (3) (or, as you need to, a
lower gear) when towing a trailer. Operating your
vehicle in THIRD
(3) when towing a trailer will
minimize heat buildup and extend the life of your
transmission.

Three important considerations have to do with weight:
0 the weight of the trailer,
0 the weight of the trailer tongue
0 and the weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 5,000 lbs. (2 270 kg).
But even that can be too heavy.
It depends on how you plan to use your rig.
For
example, speed, altitude, road grades, outside
temperature and how much your vehicle
is used to pull a
trailer are all important. And, it can also depend on any
special equipment that you have
on your vehicle. You
can

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important
weight to measure because
it affects the total or gross
weight of your vehicle. The Gross Vehicle Weight
(GVW) includes the curb weight of the vehicle, any
cargo
you may carry in it, and the people who will be
riding
in the vehicle. And if you will tow a trailer, you
must add the tongue load to the GVW because your
vehicle will be carrying that weight, too. See “Loading
Your Vehicle”
in the Index for more information about
your vehicle’s maximum load capacity.
A 6
If you’re using a weight-carrying hitch, the trailer
tongue
(A) should weigh 10 percent of the total loaded
trailer weight
(B). If you’re using a weight-distributing
hitch, the trailer tongue
(A) should.weigh 12 percent of
the total loaded trailer weight (B).
After you’ve loaded your trailer, weigh the trailer and
then the tongue, separately, to see
if the weights are
proper.
If they aren’t, you may be able to get them right
simply by moving some items around
in the trailer.
Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the limit for
cold tires.
You’ll find these numbers on the
CertiFication/Tire label on the driver’s door edge, above
the door latch or see “Tire Loading”
in the Index. Then
be sure you don’t go over the GVW limit for your
vehicle, including the weight of
the trailer tongue.
Hitches
It’s important to have the correct hitch equipment.
Crosswinds, large trucks going
by and rough roads are a
few reasons why you’ll need the right hitch. Here are
some rules to follow:

If you’ll be pulling a trailer that, when loaded, will
weigh more than 2,000 Ibs. (900 kg), be sure to use a
properly mounted, weight-distributing hitch and
sway control of the proper size. This equipment is
very important for proper vehicle loading and good
handling when you’re driving.
Will you have to make any holes
in the body of your
vehicle when you install a trailer hitch?
If you do, then be sure to seal the holes later when
you remove the hitch. If you don‘t seal them, deadly
carbon monoxide
(CO) from your exhaust can get
into your vehicle (see “Carbon Monoxide”
in the
Index). Dirt and water can, too.
Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the tongue
of the trailer
so that the tongue will not drop to the road
if it becomes separated from the hitch. Instructions
about safety chains may be provided by
the hitch
manufacturer or by the trailer manufacturer. Follow the
manufacturer’s recommendation for attaching safety
chains and do not attach them to
the bumper. Always
leave just enough slack
so you can turn with your rig.
And, never allow safety chains to drag on the ground.
Trailer Brakes
If your trailer weighs more than 1,000 lbs. (450 kg)
loaded,
then it needs its own brakes -- and they must be
adequate. Be sure to read and follow the instructions for
the trailer brakes
so you’ll be able to install, adjust and
maintain them properly.
Your trailer’s brake system can tap into the vehicle’s
hydraulic brake system only
if:
0 The trailer parts can withstand 3,000 psi
(20 650
kPa) of pressure.
0 The trailer’s brake system will use less than
0.02 cubic inch (0.3 cc) of fluid from your vehicle’s
master cylinder. Otherwise,
both braking systems
won’t work well. You could even lose your brakes.
If everything checks out this far, then make the brake
fluid tap at the port on the master cylinder that sends
fluid to the rear brakes.
But don’t use copper tubing for
this.
If you do, it will bend and finally break off. Use
steel brake tubing.

Driving with a Trailer
A CAUTION:
If you have a rear-most window open and you
pull
a trailer with your vehicle, carbon monoxide
(CO) could come into your vehicle. You can’t see
or smell CO. It can cause unconsciousness or
death. (See “Engine Exhaust” in the Index.)
To
maximize your safety when towing a trailer:
a
a
a
Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
Keep the rear-most windows closed.
If exhaust does come into your vehicle
through
a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with the
fan on any speed. This will bring fresh,
outside air into your vehicle.
Do not use
MAX A/C because.it only recirculates the
air inside your vehicle. (See “Comfort
Controls” in the Index.)
L
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 yaurself 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.
