2004 SAAB 9-3 Owners Manual

177 Starting and driving
Driving in hot climatesAlways check the coolant level before start-
ing a journey. When the engine is cold, the
coolant must not lie above the KALT/COLD
mark on the expansion tank (boundary
between the upper and lower sections of the
tank).
At the end of a journey, allow the engine to
idle for 2–3 minutes before switching it off.
If the needle on the temperature gauge
enters the red zone, the following message
will be shown on the SID:
1 Stop the car but do not switch off the
engine. Do not remove the cap on the
cooling system expansion tank, even if
the tank is empty. The engine tempera-
ture should decrease. If the temperature
continues to rise with the engine idling,
the engine must be switched off.2 If the engine is idling and the needle on
the temperature gauge falls, wait until a
normal temperature is shown (about in
the middle of the scale) before switching
off the engine. If the coolant needs to be
topped up, carefully unscrew the
expansion tank cap.
Fill as required with a mixture of 50 %
antifreeze and 50 % clean water. Use an
antifreeze approved by Saab.
3 Have the car’s cooling system checked
at a Saab dealer. Hot engine.
Make a safe stop.
Run engine on idle.
WARNING
 Exercise care when opening the hood
if the engine is overheated. Never
remove the expansion tank cap
completely when the engine is hot.
 The cooling system is pressurized -
hot coolant and vapour can escape.
These can cause injury to your eyes
and burns. Open the cap slowly to
release the pressure before removing
it.

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.

179 Starting and driving
Recommendations for cars with
automatic transmissionThe following driving time limits are based
on the capacity of the cooling system in hot
weather, i.e. approximately 86°F (+30°C).The following driving time limits are based
on the capacity of the cooling system in hot
weather, i.e. approximately 104°F (+40°C).
When negotiating long hills, bear the follow-
ing important considerations in mind.
Rises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
The following steps are taken in order as the
temperature of the transmission increases:
 Gear change pattern is altered
 A/C compressor is switched off
 Max. engine torque is reducedThe following message will be displayed on
the SID if the transmission fluid becomes
too hot:
If this message appears, stop the car as
soon as it is safe to do so and allow the
engine to idle until the message has gone
out. The selector lever should be in
position P.
When continuing your journey, manually
select a low gear in which the engine speed
is about 3,500 rpm until the incline eases
(see page 158).NOTICE Use only a genuine Saab trailer hitch,
since other models can damage the
car’s bodywork and electrical system.
 Consult a Saab dealer for guidance on
how to connect a trailer hitch.
 Exercise care when driving on uneven
roads or against the curb if the car is
heavily laden. This particularly applies
to cars with 17" wheels.

180 Starting and drivingRecommendations for cars with
manual transmissionRises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
When the needle is just outside the red
zone, the A/C compressor will be switched
off and, on certain engine variants, the max-
imum engine torque will be limited.
When continuing your journey, select a low
gear in which the engine speed is about
3,500 rpm until the incline eases.
Trailer hitch loadThe weight distribution on the trailer makes
a lot of difference to the handling properties
of the car and trailer combination. With a
two-wheel trailer, concentrate the load over
the wheels and keep it as low as possible.
The trailer should be loaded so that the load
on the towball is 110–165 lbs. (50–75 kg).
Note that this load must be included in the
total load for the car. If this now exceeds the
specified load capacity, the load in the trunk
may have to be reduced by the correspond-
ing amount.
WARNING
Remember to use engine-braking (selec-
tor position 1, 2, or 3) to spare the brakes
when you are driving on a long or steep
downhill slope.
Overheating can cause the brakes to
fade!

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.

184 Starting and drivingDriving at nightBear in mind the following points, especially
when driving at night:
 Nighttime driving requires your full
concentration
 Do not rush. Count on your journey taking
slightly longer.
 The number of drivers under the influence
of drugs is likely to be greater at night than
during the day.
 Do not stare at the headlights of oncom-
ing vehicles.
 Avoid driving at night if you have poor
eyesight. Night vision deteriorates with
age.
 Keep your car’s headlights, windows and
mirrors clean. Also, if you wear glasses,
make sure they are clean.
 Make sure you are well rested before
starting a long journey. Take a break every
other hour.
 Only eat light meals. Heavy meals have a
tendency to induce tiredness.
 Wild animals prefer to move at dusk and
dawn.
 Check the headlight levelling setting (see
page 91).
Towing the car
Front towing eye
WARNING
 Remember that the brake servo does
not operate when the engine is off.
Much greater pressure than normal
will therefore be required to operate
the brake pedal.
 Nor does the steering servo operate
when the engine is off. The steering
will therefore be much heavier than
usual.
 The towing vehicle should always be
heavier than the vehicle on tow.
 Never allow passengers to ride in the
car when it is on tow.
 Always seek professional help if the
car needs to be recovered.
 The ignition switch must be in the ON
position if the car is moved with the
engine not running.
 The steering wheel lock must be
disengaged before towing the car.
 The steering wheel lock disengages
when the remote control is inserted
into the ignition switch, if the battery
has sufficient charge.
WARNING
 Make sure that the towing eye is
screwed in tightly. It has a left-hand
thread!
 The towing eye is only designed for
towing the car on roads. It must not
be used to pull the car out of a ditch,
for example.
 Make sure that all bystanders keep a
suitable distance, in case the towing
eye or tow rope should snap. The
towing eye or tow rope could catapult
off and cause seriously injury.
 Never drive with the towing eye fitted
to the front bumper. Return it to its
designated storage space.
