Gross Vehicle Weight (GVW) and
Gross Vehicle Weight Rating
(GVWR)Gross Vehicle WeightThe Gross Vehicle Weight (GVW) must
never exceed the Gross Vehicle Weight
Rating (GVWR).
Gross Vehicle Weight (GVW) is the com-
bined total of the weight of the vehicle,
driver, passengers, luggage, trailer hitch,
trailer tongue load and any other optional
equipment installed on your vehicle.
Therefore, the GVW changes depending
on the situation. Determine the GVW each
time before going on a trip by putting your
vehicle and trailer on a vehicle scale.
Certification labelGVWR is shown on the certification plate
located on the driver’s side door jamb of
your vehicle.

The use of a genuine Saab trailer hitch is
recommended. A genuine Saab hitch is
available from your Saab dealer.If use of a non-genuine hitch is unavoid-
able, be sure the hitch is suited to your ve-
hicle and trailer. Consult with a profes-
sional hitch supplier to assist you in
choosing an appropriate hitch for your ve-
hicle. Be sure to follow all of the hitch man-
ufacturer’s instructions for installation and
use.
Never use a hitch that mounts only to the
rear bumper. The bumper is not designed
to handle that type of load.
For all types of hitches, regularly check
that the hitch mounting bolts and nuts are
tight.

Connecting a trailer
Trailer brakes
If your trailer’s total weight (trailer weight
plus its cargo weight) exceeds 1,000 lbs
(453 kg), the trailer is required to be
equipped with its own brake system. Elec-
tric brakes or surge brakes are recom-
mended, and must be installed properly.
Check that your trailer’s brakes conform
with Federal, state/province and/or other
applicable regulations. Your Saab’s brake
system is not designed to be tapped into
the trailer’s hydraulic brake system.Please ask your Saab dealer and profes-
sional trailer supplier for more information
about the trailer’s brake system.

Trailer safety chains
In case the trailer hitch connector or hitch
ball should break or become disconnect-
ed, the trailer could get loose and create a
traffic safety hazard.
For safety, always connect the towing ve-
hicle and trailer with trailer safety chains.
Pass the chains crossing each other un-
der the trailer tongue to prevent the trailer
from dropping onto the ground in case the
trailer tongue should disconnect from the
hitch ball. Allow sufficient slack in the
chains taking tight-turn situations into ac- Never drill the frame or under-body
of your vehicle to install a commer-
cial trailer hitch. If you do, danger-
ous exhaust gas, water or mud may
enter the passenger compartment
through the drilled hole. Exhaust
gas contains carbon monoxide, a
colorless and odorless gas which is
dangerous, or even lethal, if inhaled.
Also, drilling the frame or under-
body of your vehicle could cause
deterioration of strength of your ve-
hicle and cause corrosion around
the drilled hole.

Do not modify the vehicle exhaust
system, brake system, or other
systems when installing a hitch or
other trailer towing equipment.

Do not use axle-mounted hitches
as they can cause damage to the
axle housing, wheel bearings,
wheels or tires.
Adequate size trailer brakes are
required when the trailer and its
cargo exceed 1,000 lbs (453 kg)
total weight.

Do not directly connect your trail-
er’s hydraulic brake system to the
hydraulic brake system in your
vehicle. Direct connection would
cause the vehicle’s brake perfor-
mance to deteriorate and could
lead to an accident.

Driving tips
steering wheel with one hand and turn it to
the left for a left turn, and turn it to the right
for a right turn.

If the ABS warning light illuminates
while the vehicle is in motion, stop towing
the trailer and have repairs performed im-
mediately by the nearest Saab dealer.

Driving on grades

Before going down a steep hill, slow
down and shift into lower gear (if neces-
sary, use 1st gear) in order to utilize the
engine braking effect and prevent over-
heating of your vehicle’s brakes. Do not
make sudden downshifts.

When driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating.

When driving uphill in hot weather, pay
attention to the water temperature gauge
pointer (for all vehicles) and AT OIL TEMP
warning light (for AT vehicles) since the
engine and transmission are relatively
prone to overheating under these condi-
tions. If the water temperature gauge
pointer approaches the OVERHEAT zone
or the AT OIL TEMP warning light illumi-
nates, immediately switch off the air con-
ditioner and stop the vehicle at the nearest
safe place. Refer to the “Engine overheat-
ing” section in chapter 9, and “Warning
and indicator lights” section in chapter 3.
If your vehicle has an automatic trans-
mission, avoid using the accelerator pedal
to stay stationary on an uphill slope in-
stead of using the parking brake or foot
brake. That may cause the transmission
fluid to overheat.

If your vehicle has an automatic trans-
mission, place the selector lever as fol-
lows:
Uphill slopes: “D” position
Downhill slopes: A low-speed gear posi-
tion to use engine braking

Parking on a grade
Always block the wheels under both vehi-
cle and trailer when parking. Apply the
parking brake firmly. You should not park
on a hill or slope. But if parking on a hill or
slope cannot be avoided, you should take
the following steps:
1. Apply the brakes and hold the pedal
down.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, re-
lease the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then ap-
ply the parking brake; slowly release the
regular brakes.
5. Shift into 1st or reverse gear (manualtransmission) or “P” (automatic transmis-
sion) and shut off the engine.A1910BE-A-GSAAB.book Page 20 Tuesday, September 6, 2005 8:37 AM

Washing
NOTEWhen having your vehicle washed in
an automatic car wash, make sure be-
forehand that the car wash is of suit-
able type.
The best way to preserve your vehicle’s
beauty is frequent washing. Wash the ve-
hicle at least once a month to avoid con-
tamination by road grime.
Wash dirt off with a wet sponge and plenty
of lukewarm or cold water. Do not wash
the vehicle with hot water and in direct
sunlight.
Salt, chemicals, insects, tar, soot, tree
sap, and bird droppings should be washed
off by using a light detergent, as required.
If you use a light detergent, make certain
that it is a neutral detergent. Do not use
strong soap or chemical detergents. All
cleaning agents should be promptly
flushed from the surface and not allowed
to dry there. Rinse the vehicle thoroughly
with plenty of lukewarm water. Wipe the
remaining water off with a chamois or soft
cloth. In the U.S., see your dealer or visit
www.saabcatalog.com for a full line of car
care products.

Washing the underbody
Chemicals, salts and gravel used for deic-ing road surfaces are extremely corrosive,
accelerating the corrosion of underbody
components, such as the exhaust system,
fuel and brake lines, brake cables, floor
pan and fenders, and suspension.
Thoroughly flush the underbody and in-
side of the fenders with lukewarm or cold
water at frequent intervals to reduce the
harmful effects of such agents.
Mud and sand adhering to the underbody
components may accelerate their corro-
sion.
After driving off-road or on muddy or
sandy roads, wash the mud and sand off
the underbody. Carefully flush the sus-
pension and axle parts, as they are partic-
ularly prone to mud and sand buildup. Do
not use a sharp-edged tool to remove
caked mud.
NOTEBe careful not to damage brake hoses,
sensor harnesses, and other parts
when washing suspension compo-
nents.

Using a warm water washer

Keep a good distance of 12 in (30 cm)
or more between the washer nozzle and
the vehicle.

Do not wash the same area continuous-
ly.
When washing the vehicle, the
brakes may get wet. As a result,
the brake stopping distance will
be longer. To dry the brakes, drive
the vehicle at a safe speed while
lightly pressing the brake pedal to
heat up the brakes.

Do not wash the engine compart-
ment and area adjacent to it. If wa-
ter enters the engine air intake,
electrical parts or the power steer-
ing fluid reservoir, it will cause en-
gine trouble or faulty power
steering respectively.

Since your vehicle is equipped
with a rear wiper, automatic car-
wash brushes could become tan-
gled around it, damaging the wip-
er arm and other components.
Ask the automatic car-wash oper-
ator not to let the brushes touch
the wiper arm or to fix the wiper
arm on the rear window glass with
adhesive tape before operating
the machine.

capacity weight by 32 lbs (15 kg), so
the cargo weight must be reduced by
32 lbs (15 kg) or more.
Determining compatibility of
tire and vehicle load capaci-
tiesThe sum of four tires’ maximum load
ratings must exceed the maximum
loaded vehicle weight (“GVWR”). In
addition, sum of the maximum load
ratings of two front tires and of two
rear tires must exceed each axle’s
maximum loaded capacity (“GAWR”).
Original equipment tires are designed
to fulfill those conditions.
The maximum loaded vehicle weight
is referred to Gross Vehicle Weight
Rating (GVWR). And each axle’s
maximum loaded capacity is referred
to Gross Axle Weight Rating
(GAWR). The GVWR and each axle’s
GAWR are shown on the vehicle cer-
tification label affixed to the driver’s
door.
The GVWR and front and rear
GAWRs are determined by not only
the maximum load rating of tires but
also loaded capacities of the vehicle’ssuspension, axles and other parts of
the body.
Therefore, this means that the vehicle
cannot necessarily be loaded up to
the tire’s maximum load rating on the
tire sidewall.

Adverse safety consequenc-
es of overloading on handling
and stopping and on tiresOverloading could affect vehicle han-
dling, stopping distance, vehicle and
tire as shown in the following. This
could lead to an accident and possibly
result in severe personal injury.
Vehicle stability will deteriorate.
Heavy and/or high-mounted loads
could increase the risk of rollover.
Stopping distance will increase.
Brakes could overheat and fail.
Suspension, bearings, axles and
other parts of the body could break or
experience accelerated wear that will
shorten vehicle life.
Tires could fail.
Tread separation could occur.
Tire could separate from its rim.

Steps for Determining Cor-
rect Load Limit1. Locate the statement “The com-
bined weight of occupants and cargo
should never exceed XXX pounds” on
your vehicle’s label.
2. Determine the combined weight of
the driver and passengers that will be
riding in your vehicle.
3. Subtract the combined weight of
the driver and passengers from XXX
kilograms or XXX pounds.
4. The resulting figure equals the
available amount of cargo and lug-
gage load capacity. For example, if
the “XXX” amount equals 1,400 lbs
(635 kg) and there will be five- 150 lbs
(68 kg) passengers in your vehicle,
the amount of available cargo and
luggage load capacity is 650 lbs.
(1,400 – 750 (5  150) = 650 lbs.)
5. Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not safe-
ly exceed the available cargo and lug-
gage load capacity calculated in Step
4.
6. If your vehicle will be towing a trail-
er, load from your trailer will be trans-
