engine SAAB 9-5 2002 Repair Manual

173 Starting and driving
Driving in hot weather Always check the coolant level before
starting a journey. The level should be just
below the MAX mark.
 At the end of a journey, if the engine has
worked hard, allow it to idle for two or
three minutes before switching it off.
If the needle on the temperature gauge
enters the red zone:
1 Bring the car to a standstill but leave the
engine running. Do not remove the cap
on the expansion tank even if the tank is
empty. If the needle on the temperature
gauge continues to rise while the engine
is idling, switch off the engine. 2 Wait until the needle has dropped back
to indicate normal temperature (roughly
midway, in the white zone) before stop-
ping the engine. If the coolant needs top-
ping up, unscrew the cap on expansion
tank carefully.
Top up, as necessary, ideally with a
50/50 mixture of Saab-approved coolant
and water. If only water is available, use
that, but remember to have the coolant
mixture checked as soon as possible.
3 As soon as possible, have the cooling
system checked by an authorized Saab
dealer.
Towing a trailerTrailer hitch attachmentTrailer hitch attachments are available as
accessories. These are designed for a max-
imum trailer weight of 3500 lbs. (1588 kg),
see also page 249.
Use only the electrical trailer hitch socket
provided in the trailer hitch kit.
Saab recommends:
 Use a Saab original hitch kit attachment
which is designed and tested by Saab.
 Consult your Saab dealer regarding the
appropriate hitch kit for your car.
WARNING
Always undo the expansion tank filler cap
carefully, releasing the pressure and any
vapor before removing the cap com-
pletely.
NOTEUse only a genuine Saab trailer hitch and
wiring, since other wiring methods can
cause expensive damage to the car’s
body and electrical system.
Consult an authorized Saab dealer for
guidance on how to connect the trailer
hitch electrical system.

175 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 and wait until the warning
has been extinguished. When continuing
your journey, select a locked gear (1, 2 or 3)
that will allow you to drive at an engine
speed of about 3,000 rpm (see page 161). 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 178.
If the car is equipped with automatic trans-
mission, select position L when ascending
or descending steep hills.
Trailer hitch loadThe weight distribution on the trailer makes
a lot of difference to the handling properties
of the car and trailer combination. As
regards single-axle trailers, whenever pos-
sible, concentrate the load over the wheels
and keep it as low as possible.
The trailer should be loaded so that the
maximum load on the towbar ball is 5% to
7% of the trailer weight with a maximum per-
missible tongue weight of 165 lbs. (75 kg).
Note that this load must be added to the total
load for the car. If this now exceeds the
specified load capacity, the load in the lug-
gage compartment will have to be reduced
by a corresponding amount.
WARNING
Remember to use engine-braking (selec-
tor position L, 3, or 4) to spare the brakes
when you are driving on a long or steep
downhill slope.
Brake failure can result from overheated
brakes!
NOTEIf the ”Automatic transmission, fault indi-
cator” indicator comes on, cease
towing until the problem has been recti-
fied.

Driving 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).
NOTETo 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 134 and 137.
NOTEDo 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.

180 Starting and drivingTowing the carTransporting the carFront 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 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 being towed.
 Always seek professional help if the
car needs to be towed.NOTEIf 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. If the
towing eye were to shear suddenly, it
could cause serious injury.
 Always seek professional help if the
car needs to be recovered.
NOTE 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.

181 Starting and driving
Rear 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
with manual transmission Gear lever in neutral and parking lights on.
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.
Considerations when towing the car
with automatic transmission Selector lever at N (neutral) and parking
lights on.
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. 1 Selector lever in position N.
2 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
distance is 25-30 miles (40-50 km). If the
car has to be transported farther than
that, summon a tow truck. A flat bed tow
truck is the preferred 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 possi-
ble to start the engine using jump leads (see
the section, ”Jump starting” on page 182). NOTE 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.

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.

186 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 tar paulin - not
one made of plastic.
