WARNING
The system improves ride comfort and
safety during normal driving. It must
however not be regarded as a system
to enable the driver to maintain higher
speeds. The same precautions as
normal for safe cornering and driving
on slippery roads must be adopted (see
pages 169/ 171).

179 Starting and driving
Economical drivingFactors affecting fuel
consumptionThe fuel consumption of a car is greatly
affected by driving conditions, climate, road
conditions, speed, driving technique, etc.Breaking-inFuel consumption may be somewhat
higher during the break-in period (the
first 3,000–4,000 miles (5,000–7,000 km)).Weather conditionsSummer temperatures give better fuel
economy than winter ones. The difference
can be as much as about 10%. Consump-
tion increases in cold weather because the
engine takes longer to reach its normal
operating temperature. The transmission
and wheel bearings also take longer to
warm up. Even distance affects consump-
tion: short journeys of 3–5 miles (5–8 km)
do not give the engine enough time to
reach its optimum temperature. Wind con-
ditions also have a marked effect on fuel
consumption.How to read the diagram:
If fuel consumption with the engine at
normal temperature is 28 mpg (10 l/
100 km), the actual fuel consumption
3 miles (5 km) after the engine has started
from cold will be:
– 23.5 mpg (12 l/100 km) at outside temp.
of 68°F (+20°C) (increase of 20%).
– 17.7 mpg (16 l/100 km) at outside temp.
of 32°F (0°C) (increase of 60%).
– 14 mpg (20 l/100 km) at outside temp.
of –4°F (–20°C) (increase of 100%).
It is clear from the diagram that both dis-
tance driven and outside temperature have
a significant impact on fuel consumption,
after a cold start.
If the car is normally driven on short jour-
neys, 3–5 miles (5–8 km), for example to
and from work, the average consumption
will be 60–80% above the normal level.
Driving techniques To obtain the best running economy, with
regard to fuel consumption and general
wear, the car must be serviced regularly.
 High speed, unnecessary acceleration,
frequent braking and much changing
down all give higher fuel consumption.
 Frequent gear changing in traffic, starting
in cold weather, the use of studded tires
and roof racks, and towing a camper all
increase fuel consumption.
 Do not warm up the engine while the car
is stationary.
If idling, the engine will take much longer
to reach its optimum temperature, and Percentage increase in fuel consumption
of engine starting from cold compared to
engine at normal temperature.

181 Starting and driving
Driving in cold weatherIn cold weather, special attention should be
paid to the following:
 Before driving off, make sure that the
wiper blades have not frozen to the wind-
shield.
 Remove any snow from the heating
system air intakes between the hood and
the windshield.
 If necessary, inject oil into the locks to
prevent them from freezing. Use molyb-
denum-sulphide oil (MoS
2). If the locks
freeze, exercise care when unlocking the
car (manual unlocking) to avoid breaking
the key. Warm up the key or use a de-icer.
 It is particularly important when the roads
are slippery that the brakes and tires are
in good condition.
 For how to check the level of antifreeze in
the engine coolant, see page 205.
 Add gasoline anti-freeze when refueling
several times before the onset of winter.
This will prevent condensation water in
the fuel tank from freezing and causing
interruptions in the fuel supply. The likeli-
hood of condensation is lowest when the
fuel tank is full.
If the car is parked outside and the
temperature is below zero, gasoline anti-
freeze is of little use as it cannot remove
water that has already frozen. Park the
car in a warm place so that any ice that
may have built up melts, then add gaso-
line anti-freeze when refueling.Condensation is caused by temperature
fluctuations, either in the outside temper-
ature alone or when the car is alternately
parked outdoors and in a garage.
Convertible: Avoid operating the soft top
at temperatures below 23°F (–5°C).
 The car is equipped with tires designed to
provide optimum grip on both wet and dry
roads, although this has been achieved at
the expense of somewhat reduced grip on
snow and ice. For regular driving on snow
and ice, we therefore recommend that
winter tires be fitted. However, winter tires
achieve this extra grip at the expense of
grip on bare road surfaces.
Winter tires, particularly studded tires, gen-
erally make driving safer on snow and ice.
Acquaint yourself with the legal provi-
sions governing the use of different
types of winter tires and snow chains.
Studded tires are not allowed in some
countries. If winter tires are fitted, the same
type must be fitted to all four wheels. Your
Saab dealer will be pleased to advise you on
the best tires for your car.
ProCarManuals.com

182 Starting and drivingRemember that tires age: it may therefore
be necessary to change winter tires before
they reach the legal wear limit, as they grad-
ually lose their friction properties with age.
If you get into a front wheel skid and the car
has a manual transmission, the best
response is to freewheel, which means
declutching so that the wheels neither drive
nor brake, and to cautiously steer in the
desired direction.
If the car has automatic transmission, ease
off the accelerator slightly and steer cau-
tiously in the desired direction.
If you get into a rear wheel skid, steer in the
same direction as the movement of the rear
of the car.
Driving with tire chainsSnow chains must only be fitted to the wheel
and tire dimensions that Saab recommends
in "Technical data" on page 267.
Contact a Saab dealer regarding approved
tire chains. See also page 240.
WARNING
 Do not drive at speeds above 30 mph
(50 km/h) when tire chains are fitted.
 Tire chains can reduce directional
stability.
 Do not fit tire chains to the car’s rear
wheels.NOTICE Check the links frequently for wear.
 Check that the chains do not foul the
wheel arch liner at full lock.
 Refer to the "Technical data" section
on page 267, for information on wheel
and tire dimensions approved for the
fitting of tire chains.

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.

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.

234 Car careTiresYour new vehicle comes with high-quality
tires made by a leading tire manufacturer. If
you ever have questions about your tire
warranty and where to obtain service, see
your Saab Warranty and Service Record
Booklet for details.
Inflation - Tire PressureThe Tire-Loading Information label shows
the correct inflation pressures for your tires
when they’re cold. “Cold” means your vehi-
cle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).Notice:
Don’t let anyone tell you that
underinflation or overinflation is all
right. It’s not. If your tires don’t have
enough air (underinflation), you can get
the following:
 Too much flexing
 Too much heat
 Tire overloading
 Bad wear
 Bad handling
 Bad fuel economy
If your tires have too much air (overinfla-
tion), you can get the following:
 Unusual wear
 Bad handling
 Rough ride
 Needless damage from road hazardsAdjust the tire pressure to match the current
load and speed of the car (see page 277).
The stated tire pressures apply to cold tires,
i.e. tires that are the same temperature as
the outside air temperature. Tire pressure
increases as the tires become warm (e.g.
during highway driving) by approximately
0.3 bar (4 psi). When the temperature of the
tires changes by 50°F (10°C), the tire pres-
sure will change 0.1 bar (2 psi).
Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
WARNING
Poor maintained and improperly used
tires are dangerous.
 Overloading your tires can cause
overheating as a result of too much
friction. You could have an blow-out
and a serious accident. See “Loading
Your Vehicle” on page 243.
 Underinflated tires pose the same
danger as overloaded tires. The
resulting accident could cause serious
injury. Check all tires frequently to
maintain the recommended pressure.
Tire pressure should be checked
when your tires are cold.
 Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact – such as when you hit a
pothole. Keep tires at the recom-
mended pressure.
 Worn, old tires can cause accidents. If
your tread is badly worn, or if your tires
have been damaged, replace them.
