ECU SAAB 9-3 2004 Owner's Guide

178 Starting and drivingTowing a trailerMake sure you are familiar with the legal
requirements regarding speed limits for
towing, maximum trailer weights, trailer
braking requirements, and also any spe-
cial driving licence provisions.
Trailer hitch attachmentTrailer hitch attachments are available as
accessories. These are designed for a max-
imum trailer weight of 3500 lbs (1588 kg),
with trailer brakes.
An electrical socket is provided for connect-
ing the trailer electrics. This is located under
the floor trim by the left-hand tail light.
The Saab genuine electrical socket enables
a battery in the trailer on tow to be charged
while driving. Also, if the car has SPA, this
is deactivated automatically if a trailer is
hitched up and correctly connected to the
Saab genuine trailer socket.
Saab recommendations:
 Use a genuine Saab trailer hitch that is
designed and tested for your Saab.
 Contact your Saab dealer for advice on
which trailer hitch is designed for your car.
WARNING
 Do not drive with a trailer on inclines
steeper than 15 %. The load on the
drive (front) wheels will be so low that
the wheels can start to spin and
prevent further progress.
 In addition, the car’s parking brake
may not always be sufficient to hold
the car and trailer securely, as the
wheels may start to slide.
 Always apply the trailer’s parking
brake when unhitching it. There is
otherwise a risk of personal injury or
damage to the bumper should the
trailer start to roll.
 When you hitch up the trailer be sure
to attach its safety chains to the holes
by the hitch.

181 Starting and driving
Checks before drivingMake sure that the car and trailer are in
good working order. This is essential since
towing a trailer increases the strain on the
car.
 Check and if necessary adjust the tire
pressure of the car and trailer.
 Make sure all wheel bolts are properly
tightened.
 Make sure that the equipment joining the
car and trailer is properly secured and
adjusted.
 Make sure the trailer’s electrical cable is
properly connected and is not so long that
it drags along the ground. Also, make
sure the cable is not too short and risks
breaking when turning a corner.
 Check all bulbs.
 Check the car and trailer brakes.
 Make sure that all items on or in the
camper or trailer are properly secured.
 Make sure that the trailer’s jockey wheel
is raised and locked.
 Check the distribution of the load so that
the car and trailer are well balanced.
 Check that the rearview mirrors provide
the best possible rearward vision.
 Make sure the trailer’s safety cable is
correctly attached.
Driving considerationsAlways take extra care when towing a
trailer, as the car’s handling will be different
and its braking performance reduced. The
trailer’s braking system and suspension
also have a considerable effect on these
characteristics. See also "Driving with a
load" on page 183.
Drive carefully:
 descending hills
 on uneven roads
 over railway crossings
 when meeting large vehicles
If the car has automatic transmission, select
gear M1 when ascending or descending
steep hills.ReversingGet someone to help you keep an eye out
behind the trailer as the door mirrors do not
always provide sufficient rearward vision
when reversing.
NOTICEIf the camper or trailer has additional elec-
trical equipment, besides the standard
exterior lighting (e.g. interior lighting, a
fan or a charger for a separate battery)
and it is connected to the car via the trailer
connector, to be provided with a separate
power supply, the camper or trailer must
have a 13-pin connector as specified in
ISO 11446.

182 Starting and drivingDriving with a roof rack
loadThe maximum permissible roof load is
220 lbs. (100 kg). Note that the roof load
must be included in the car’s maximum per-
missible payload and axle load.
Strong, sturdy roof carriers designed spe-
cially for your car are available from your
Saab dealer. Always secure roof loads
securely.
1 Open the four covers on the roof of the
car.
2 Insert a screw with washer into each roof
carrier foot. Fit a seal onto each screw.
3 The roof carriers are marked front and
back.
4 Bolt the roof carriers to the brackets in
the roof.5 Check that the roof carriers are firmly
mounted.
WARNING
 A roof load will affect the car’s center
of gravity and aerodynamics. Be
aware of this when cornering and driv-
ing in crosswinds.
 Adjust your speed to the prevailing
conditions.
 Due to higher aerodynamics drag, fuel
economy may suffer when driving with
a roof rack.

183 Starting and driving
Driving with a loadThe handling characteristics are affected by
how the car is loaded.
 Place the heaviest load as far forward and
as low as possible in the trunk.
 Secure the load to the lashing eyes (see
page 137).
 Heavy loads mean that the car’s center of
gravity is further back. As a result, the car
will sway more during evasive steering.
 Never exceed the permissible load of the
roof box, even if there is room for more.
 Ensure that the tire pressure is correct –
slight overinflation is preferable to under-
inflation.
 The braking distance of a loaded car is
always greater. Keep your distance from
the vehicle in front.
 Do not exceed the car’s permissible
gross vehicle weight or axle load (see
page 268).
 Roof loads can negatively affect telecom-
munication.
For further information on tires see page
231.
Driving with the trunk lid
openAvoid driving with the trunk lid partly or fully
open, since exhaust fumes can be drawn
into the cabin.
If you must drive with the trunk lid open,
close all windows and the sunroof (if fitted)
and set the cabin fan to its highest speed
setting.
Driving in deep waterNOTICEDo not drive in puddles or water deeper
than 7 in. (20 cm) and do not drive faster
than 3–4 mph. Water can otherwise be
sucked into the engine. The engine will be
seriously damaged if water enters the
intake system.

186 Starting and drivingAlways try to keep the towrope taut by
gently applying the brake of the car on tow,
as necessary. This will avoid the towrope
being jerked violently.
Cars with automatic transmission:
Always observe the speed limit for vehicles
on tow. Whatever the speed limit, the car
must not be towed at speeds exceeding
30 mph (50 km/h) nor for a distance of more
than 30 miles (50 km). If the car needs to be
transported over a longer distance, a tow
truck or flatbed truck must be called out.
The engine cannot be started by towing or
pushing the car. In an emergency, the
engine can be started as described under
"Jump starting" on page 187.
Vehicle recoveryIf the car has to be transported on a flatbed
truck, or similar, it must be securely
strapped down. There are attachment
points for this purpose on the underside of
the car. The attachment points are oblong
hole that have been reinforced to cope with
the stresses that arise during this type of
transport.
Transporting the car
NOTICE
 The car must be towed front first.
 If the car is to be towed with the front
wheels off the ground, make sure the
parking brake is off, as this acts on the
rear wheels.
NOTICEIf a car with sports (lowered) chassis is
transported, for example on a flat bed
truck, take extra care not to damage the
spoiler and/or underbody.

187 Starting and driving
Driving with the
compact spare tireObserve the following when the compact
spare tire is fitted:
 The compact spare is light and easy to
handle when changing a tire.
 Do not drive further than necessary with
the compact spare fitted - the maximum
life of the tire is only just over 2,000 miles
(approx. 3,500 km).
 Refit the standard tire as soon as possi-
ble.Important considerations when driving with
a compact spare tire:
 The car’s ground clearance is reduced.
 The car must not be driven with more than
one compact spare tire at a time.
 Avoid driving against the curb.
 Do not use snow chains.
 Do not fit the wheel cover - this would
conceal the warning text.
Jump starting
WARNING
 Do not exceed 50 mph (80 km/h). The
tire can overheat affecting the car’s
roadholding.
 Tire pressure: refer to page 275.
 The spare tire or punctured tire must
be stowed under the trunk floor, and
secured in place with the retaining nut.
NOTICETo avoid damaging a alloy wheel of a
punctured tire, this can be temporarily
placed outside up in the spare wheel well
but only while driving to the closest work-
shop.
As a general rule, all heavy loads must be
well secured in the trunk (see page 137).
WARNING
 When working on the battery, highly
explosive gas can build up. A spark
could ignite this gas that collects
around the battery. Therefore, always
avoid sparks and open flames in the
vicinity of the battery.
 The battery contains corrosive sulphu-
ric acid. Always wear a face mask or
goggles when working on the battery.
 If battery acid gets into the eyes or
splashes onto skin or clothing, wash
the affected area liberally with water. If
acid gets into the eyes or a large quan-
tity makes contact with the skin, seek
medical help.

Tire Chains
Notice:
If your vehicle does not have
P225/45R17 size tires, use tire chains
only where legal and only when you
must. Use only SAE Class ²S² type
chains that are the proper size for your
tires. Install them on the front tires and
tighten them as tightly as possible with
the ends securely fastened. Drive slowly
and follow the chain manufacturer’s
instructions. If you can hear the chains
contacting your vehicle, stop and
retighten them. If the contact continues,
slow down until it stops. Driving too fast
or spinning the wheels with chains on
will damage your vehicle.If a Tire Goeas Flat
It’s unusual for a tire to “blowout” while
you’re driving, especially if you maintain
your tires properly. If air goes out of a tire,
it’s much more likely to leak out slowly. But
if you should ever have a “blowout”, here are
a few tips about what to expect and what to
do:
If a front tire fails, the flat tire will create a
drag that pulls the vehicle toward that side.
Take your foot off the accelerator pedal and
grip the steering wheel firmly. Steer to main-
tain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts
much like a skid and may require the same
correction you’d use in a skid. In any rear
blowout, remove your foot from the acceler-
ator pedal. Get the vehicle under control by
steering the way you want the vehicle to go.
It may be very bumpy and noisy, but you can
still steer. Gently brake to a stop – well off
the road if possible.
If a tire goes flat, the next part shows how to
use your jacking equipment to change a flat
tire safely.
WARNING
If your vehicle has P225/45 R17 size tires,
don’t use tire chains, there’s not enough
clearance.
Tire chains used on a vehicle without the
proper amount of clearance can cause
damage to the brakes, suspension or
other vehicle parts. The area damaged by
the tire chains could cause you to lose
control of your vehicle and you or others
may be injured in a crash.
Use another type of traction device only if
its manufacturer recommends it for use
on your vehicle and tire size combination
and road conditions. Follow that manu-
facturer’s instructions. To help avoid
damage to your vehicle, drive slowly,
readjust or remove the device if it’s
contacting your vehicle, and don’t spin
your wheels.
If you do find traction devices that will fit,
install them on the front tires.
