2003 SAAB 9-5 engine

183 Starting and driving
Use Normal mode when driving with a trailer
or trailer on hilly roads. The adaptive gear
change pattern function will prevent the
transmission from overheating.
Rises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
The following can also occur:
 the A/C-compressor can be shut off
 the gear-change pattern is changed
 the CHECK message TRANSMISSION
OVERHEATING can appear on the SID
If TRANSMISSION OVERHEATING
appears on the SID, stop the car as soon as
it is safe to do so, switch off the engine and
open the hood. Wait several minutes and
then turn on the ignition to check that the
message has been extinguished. When
continuing your journey, select manual
mode (M) and a gear in which the engine
speed is about 3,000 rpm (see page 168). Do not drive continuously with the WINTER
mode selected in hilly country when you are
towing a trailer, as this will increase fuel con-
sumption and risk overheating the transmis-
sion.
Driving considerations Always take extra care when towing a
trailer, as the car’s handling will be different
and its braking effect reduced. The trailer’s
braking system and suspension also have a
considerable effect on these characteris-
tics, see also ”Driving with a load” page 187.
If the car has automatic transmission, select
position D when ascending steep hills. This
ensures that the adaptive gear change pat-
terns are operational, see page 169. Use
position D or L for steep descents.
WARNING
Remember to use engine-braking (selec-
tor position D or L) to spare the brakes
when you are driving on a long or steep
downhill slope.
Brake failure can result from overheated
brakes!
NOTICEIf the ”Automatic transmission, fault indi-
cator” indicator comes on, cease
towing until the problem has been recti-
fied.

188 Starting and drivingDriving considerations
with compact spare
wheel/tire fittedThe following should be observed when the
compact spare wheel (T115/70 R16) is
fitted:
The compact spare is light and easy to
handle when changing the wheel. Do not
drive further than necessary with the com-
pact spare fitted – the maximum life of the
wheel is only just over 2000 miles
(3,500 km). Have the standard wheel
repaired and refitted as soon as possible. The car’s ground clearance is reduced with
the compact spare fitted. Note that only one
compact spare wheel may be used at any
time. Take care not to hit the curb and do not
fit snow chains. Leave the wheel cover off,
so that the warning text is readily visible.
Driving with the trunk
lid/tailgate openAvoid driving with the trunk lid/tailgate partly
or fully open, since exhaust fumes can be
drawn into the cabin.
If you must drive with the trunk lid/tailgate
open, all windows and the sunroof (if fitted)
must be closed and the cabin fan on at its
highest speed setting.Driving in deep water
WARNING
Do not exceed 50 mph (80 km/h) as the
tire can overheat and adversely affect the
handling of the car.
The tire should be inflated to 60 psi
(420 kPa).
NOTICETo avoid damaging a punctured alloy
wheel it can be placed outside up in the
spare-wheel well but only while driving to
the closest workshop.
A general rule is that all heavy loads must
be well secured in the luggage compart-
ment, see page 141 and 144.
NOTICEDo not drive in water deeper than
12 inches (30 cm) and do not drive faster
than at idling speed. Water can otherwise
be sucked into the engine. The engine will
be damaged if water enters the intake
system. The car´s electrical systems may
also be affected.

189 Starting and driving
Towing the carTransporting the car Front towing eye
The front towing eye is stored with the spare
wheel.
The attachment point (tapped hole) for the
towing eye is midway along the engine sub-
frame at the front of the car.
Remove the plastic plug and screw in the
towing eye securely.
To ensure that the towing eye is in far
enough, insert the handle of the wheel
wrench through the eye for additional lever-
age.
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 pump 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 being towed.
 Always seek professional help if the
car needs to be towed.NOTICEIf a car with a sport (lowered) chassis is
transported, for example on a flat bed
truck, take extra care not to damage the
spoiler and/or underbody.
WARNING
 Make sure that the towing eye at the
front is screwed in tightly.
 The towing eye is only designed for
use when the car is being towed on the
road. 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 break. The
towing eye or tow rope could catapult
off and cause seriously injury.
NOTICE Do not drive the car with the front
towing eye in position. If it catches the
curb, for example, the engine sub-
frame could be damaged.
 Refit the plastic plug in the hole when
the towing eye has been removed, to
keep dirt and moisture out of the
threads.

190 Starting and drivingRear towing eyeThe car has a permanently mounted towing
eye at the back. If the car is equipped with a
trailer hitch, this can be used instead of the
towing eye.
Considerations when towing the car Gear lever in neutral (in cars with automatic
transmission: selector lever at N (neutral))
Turn on the parking lights.
Drive carefully and do not exceed the
speed limit for vehicles being towed.
Always try to keep the towrope taut by
gently applying the brake, as necessary.
This will avoid the towrope being jerked
violently.
. The local regulations on towing speeds
must be followed.
The highest permissible towing speed is 30
mph (50 km/h), unless the legal limit is
lower. The longest permissible towing dis-
tance is 30 miles (50 km). If the car has to
be transported farther than that, summon a
tow truck. A flat bed tow truck is the pre-
ferred method to tow.
Failure to follow these guidelines can result
in damage.
Cars with automatic transmission cannot
be bump started. In an emergency, it is pos-
sible to start the engine using jump leads
(see the section, ”Jump starting” on page
191). NOTICECars with automatic transmission:
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.
Never use the towing eyes to pull the
car unstuck.

192 Starting and driving
5 Check that the jumper cables do not
have loose or missing insulation. If they
do, you could get a shock and also the
vehicles could be damaged.
Before you connect the cables, here are
some basic things you should know.
Positive (+) will go to positive (+) and
negative (–) will go to a major metal
engine part with a good ground. Do not
connect (+) to (–) or you will get a short
that could injure you or would damage
the battery and maybe other parts as
well.
6 Connect the red positive (+) cable to the
positive (+) terminal of the vehicle with
the discharged battery.
7 Do not let the other end touch metal.
Connect it to the positive (+) terminal of
the good battery. Use a remote positive
(+) terminal if the vehicle has one.
8 Now connect the black negative (–)
cable to the good battery’s negative ter-
minal.9 Attach the cable at least 18 inches
(45 cm) away from the discharged bat-
tery, but not near engine parts that
move. To avoid an arc which could det-
onate the hydrogen gas around the bat-
tery, the final connection must be at least
18” from the battery.
10 Start the vehicle with the good battery
and run the engine for a while.
11 Try to start the vehicle with the dis-
charged battery. If it does not start after
a few tries, it probably needs service.
12 Remove the cables in reverse order to
prevent electrical shorting. Take care
that they do not touch each other or any
other metal.
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.
WARNING
Using a match or flame of any kind near a
battery can cause battery gas to explode.
You can suffer burns or be blinded. Use a
flashlight if you need more light.
Be sure the battery has enough water.
The battery installed in your new Saab
has filler caps. Be sure the right amount
of water is there. Add distilled or boiled
water if the level is too low. If you don’t,
explosive gas could be present.
Be sure the electrolyte in the battery is not
frozen. Discharged batteries will freeze.
When connecting jumper cables to a
frozen battery, gas from the chemical
reaction inside the battery can build up
under the ice and cause an explosion.
Battery fluid contains acid that can burn
you. Do not get it on you. If you acciden-
tally get it in your eyes or on your skin,
flush the area with water and get medical
help immediately.
WARNING
Do not let the other end touch anything
until the next step. The other end of the
negative cable does not go to the dead
battery. It goes to a major metal part with
a good ground on the engine of the vehi-
cle with the discharged battery.

196 Starting and drivingParking on a hillWhen parking on a steep hill, turn the front
wheels so that they will be blocked by the
curb if the car should move. Long-term parkingIf the car is not going to be used for some
time, e.g. 3–4 months, the following steps
are recommended:
 Run the engine to normal temperature
before long-term parking.
 Drain the washer-fluid reservoir and
hoses.
 Wash and wax the car. Clean the rubber
seals on the hood, luggage compartment
lid and doors, and lubricate them with
glycerol (glycerin).
 After washing the car, dry the brake discs
by taking the car out on the road and
applying the brakes a few times.
 Fill the fuel tank with fuel to prevent con-
densation 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 park-
ing brake OFF!
 Disconnect the negative (–) battery lead.
If frost is likely to occur during the
long-term parking, remove the battery
and store it away from the frost.
 Ideally, the car should be put up on
blocks, with the wheels off the ground. If
this is not possible, inflate the tires to
about 43 psi (300 kPa).  Leave all the windows open a crack and
cover the car with a fabric tarpaulin – not
one made of plastic.
