2004 SAAB 9-3 battery

145 Starting and driving
If the diagnosis function detects a fault in the
engine management system, the light
"Engine malfunction (CHECK ENGINE)" in
the instrument panel will come on (see page
75). Have the car checked at a Saab dealer
as soon as possible.
The following message is shown on the SID:
Important considerations with
catalytic convertersThe catalytic converter is an emission con-
trol device incorporated in the car’s exhaust
system. It consists of a metal canister with a
honeycomb insert, the cells of which have
walls coated in a catalytic layer (precious
metal alloy).
To ensure that the catalytic converter con-
tinues to function properly, and also to avoid
damage to the converter and its associated
components, the following points must be
observed: Have the car serviced regularly in accord-
ance with the service program.
 Always be alert to any misfiring of the
engine (not running on all cylinders) and
any loss of power or performance. At the
first sign of a malfunction, reduce speed
and take the car to a Saab dealer.
 If the engine fails to start (in severe cold
or if the battery is flat), the car can be
bump started (manual transmission only)
or started using jump leads to a donor
battery. However, as soon as you have
started the engine, it is important that it
runs on all cylinders. If it is misfiring, allow
it to idle for up to 5 minutes to give it time
to settle and run smoothly. If, after this
time, the engine still fails to run properly,
switch off the engine to avoid serious
damage to the catalytic converter.
Contact a Saab dealer for advice. Reduced engine power.
Contact Saab dealer.
NOTICEIf "Engine malfunction (CHECK
ENGINE)" warning light starts to flash
(indicating that the engine is misfiring and
the catalytic converter can be damaged),
ease off the accelerator slightly. The light
should go out or start to shine constantly.
If the light continues to flash despite
easing off the accelerator, you may
continue to drive the car but at the mini-
mum throttle permitted by the current traf-
fic situation. Have the car checked as
soon as possible at a Saab dealer.
NOTICEUse only unleaded gasoline. Leaded
gasoline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.

156 Starting and drivingLimp-homeIf the transmission malfunctions, the control
module will activate limp-home mode. In
this mode, only 2nd and 5th gears are avail-
able. Select 2nd gear when driving at low
speeds and 5th gear at higher speeds. 2nd
gear must be selected manually. Select 5th
gear manually or move the selector lever
to D (see page 158).

NOTICEDue to electrical problems it may not be
possible to move the selector lever out of
the park position, even if the ignition is
ON. If for some reason the selector lever
has to be moved out of the park position
(i.e. to tow the car a short distance) do as
described below.

169 Starting and driving
Long-term parkingIf the car is not going to be used for some
time, e.g. three to four months, the following
steps are recommended:
 Drain the washer fluid reservoir and
hoses.
 Wash and wax the car. Clean the rubber
seals on the hood, trunk lid and doors,
and lubricate them with glycerol
(glycerine).
 After washing the car, dry the brake discs
to avoid corrosion by taking the car out on
the road and applying the brakes a few
times.
 Fill the fuel tank to prevent condensation
forming in it.
 Top up the coolant and check the anti-
freeze before the onset of winter. Park the car in a dry, covered and well-
ventilated building. Leave the parking
brake OFF!
Convertible: If the car is stored, the soft
top should be closed.
 If necessary, use wheel chocks and leave
the parking brake off.
 Disconnect the negative (–) battery lead.
If frost is likely to occur during the storage
period, remove the battery and store it in
a frost-free place.
 If it is not possible to stand the car on axle
stands, increase the tire pressure to
43 psi (3 bar).
Leave all the door windows open a crack
and cover the car with a non-plastic
tarpaulin – not one made of plastic which will
not breath.

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.

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.

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.

188 Starting and drivingIt is essential when a donor battery is to be
used to jump start the car that the jump
leads be connected correctly to prevent
arcing.
To jump start your vehicle:
1 Check the other vehicle. It must have a
12-volt battery with a negative ground
system.2 Get the vehicles close enough so the
jumper cables can reach, but be sure the
vehicles are not touching each other. If a
poor connection on the negative jumper
cable should exist, it is possible for
damage to be caused to electrical
systems/components of either vehicle
should inadvertent contact be made.
You would not be able to start your car
and bad grounding could damage the
electrical systems.
3 Turn off the ignition on both vehicles.
Turn off lights that are not needed, and
radios. This will avoid sparks and help
save both batteries and it could save
your radio.4 Open the hood and locate the battery.
Find the positive (+) and negative (–) termi-
nals on the battery.NOTICEIgnoring these steps could result in costly
damage to your vehicle that would not be
covered by your warranty.
Trying to start your car by pushing or pull-
ing it could damage your vehicle, even if
you have a manual transmission. If you
have an automatic transmission, your
vehicle cannot be started by pushing or
pulling it.
NOTICEIf the other system is not a 12-volt system
with a negative ground, both vehicles can
be damaged.
WARNING
You could be injured if the vehicles roll.
Set the parking brake firmly on each vehi-
cle. Put an automatic transmission in P
(Park) or a manual transmission in
Neutral.
NOTICEIf you leave your radio on, it could be
badly damaged. The repairs would not be
covered by your warranty.
WARNING
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.Jump starting
