175 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.

180 Starting and drivingengine wear is at its greatest during this
period. Drive off as soon as possible after
starting the engine and avoid high engine
speeds.
 Drive as smoothly and thoughtfully as
possible. Match your driving to the
prevailing traffic conditions.
 Driving in a low gear gives rise to higher
fuel consumption than driving in a high
gear because of the higher engine speed
for any given road speed. Always shift up
as soon as traffic conditions allow and
drive in the highest gear as much as
possible.
 Check the tire pressure once a month.
Incorrect tire pressure increases tire
wear. It is preferable for the tire pressure
to be slightly high than too low. Under-
pressure increases fuel consumption. Check the fuel consumption regularly.
Increased fuel consumption can indicate
that something is wrong and that the car
needs to be checked at a Saab dealer.
Practical road tests have demonstrated that
substantial savings in fuel consumption can
be made if the above advice is followed.
Road conditionsWet roads increase fuel consumption, as do
unpaved roads and driving in hilly country
(the amount of fuel saved driving downhill is
less than the additional amount required to
climb the hill).
Engine block heater (standard equipment in Canada, acces-
sory in U.S.)
The following are just some of the benefits
to the car and the environment of using an
engine block heater:
 Lower fuel consumption.
 Reduced wear on the engine.
 Inside of car warms up faster.
 Exhaust emissions substantially reduced
over short runs.
The engine heater is effective at outside
temperatures up to 60–70°F (+15–+20°C).
The warmer it is outside, the shorter the time
the engine heater needs to be connected.
Longer than 1.5 hours is unnecessary.
If the car is equipped with a removable,
electric cabin heater that is not in use, store
this in the trunk.
WARNING
Never switch off the engine while driving
as the effect of the brakes and power
steering will be greatly reduced.

187 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 189.
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.
ProCarManuals.com

189 Starting and driving
Driving with a loadThe handling characteristics are affected by
how the car is loaded.
Driving with the trunk lid
openIf you must drive with the trunk lid open,
close all windows and the sunroof (if
equipped) and set the cabin fan to its high-
est speed setting.
Driving in deep water
NOTICE Place the heaviest load as far forward
and as low as possible in the trunk.
 Secure the load to the lashing eyes
(see page 143).
 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
underinflation.
 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 tele-
communication.
For further information on tires see
page 234.
WARNING
Avoid driving with the trunk lid partly or
fully open, since exhaust fumes can be
drawn into the cabin.
NOTICEDo 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.

190 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 96).
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.

193 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 143).
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.

196 Starting and drivingFor long tripsBefore starting off on a long journey, it is
advisable to have your car inspected by
your Saab dealer.
Obtain a few important items to take along
on your journey, such as spare bulbs, wiper
blades, fuses, a drive belt (poly-V-belt) and
the like.
You can check some points yourself before-
hand:
 Check that no oil or fuel leaks out of the
engine or gearbox/transmission.
 Check the coolant and power steering
fluid levels. Check also for leaks.
 Inspect the drive belt (poly-V-belt) and
replace if it shows any signs of wear.
 Check the battery charge.
 Check the tires for tread pattern and air
pressure, including the compact spare
tire.
 Take an extra remote control and keep it
separate.
 Check the brakes.
 Check all bulbs.
 Check for the presence of the tool kit and
jack in the car.
