155 Starting and driving
Electronic Stability
Program (ESP)The Electronic Stability Program employs
both the antilock braking system (ABS) and
the traction control system (TCS). It is a
system that helps the driver to stabilize the
car in unusual circumstances that can oth-
erwise be difficult to handle.
How the ESP system worksThe Electronic Stability Program can help to
prevent the car from skidding by braking
one or several wheels independently of the
driver. The engine output is then also
reduced to prevent the driving wheels from
spinning. The car has sensors that measure
wheel speed, yaw acceleration, lateral
acceleration, steering wheel position and
braking pressure. The values provided by
these sensors are used to calculate the
actual direction of the car. If this direction
does not agree with that intended by the
driver, calculated from the steering wheel
position, the ESP is engaged.
ESP improves the driver’s chances of
retaining control over the car in critical situ-
ations.
To ensure that the system works as
designed, the dimensions of all four tires
must be the same.
WARNING
When driving normally, ESP will help to
improve the stability of the car. This does
not mean that car can be driven faster.
The same care and prudence as normally
applied should be displayed on cornering
and when driving on slippery roads.

160 Starting and drivingIf winter tires are fitted, the same type must
be fitted on all wheels. Your Saab dealer will
be pleased to advise you on the best tires for
your car.
Remember that tires age. It may therefore
be necessary to change them before they
reach the legal wear limit, as they gradually
lose their friction properties.
The best response if the car gets into a front-
wheel skid is to freewheel (manual gearbox
only), i.e. disengage the clutch (so that the
wheels are neither driven or retarded by the
engine.
If the car has automatic transmission, ease
up on the accelerator and steer carefully in
the desired direction.
In a rear-wheel skid, steer in the same direc-
tion that the rear of the car is moving.
Tire chainsIf you want to fit tire chains (where legally
permitted) they should only be fitted to the
tires recommended under ”Specifications”
(see page 260).
Consult your Saab dealer for details of
approved tire chains.
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.
WARNING
Do not exceed 30 mph (50 km/h)
when tire chains are fitted.
Tire chains can reduce the directional
stability of the car.
Tire chains must not be used on the
rear wheels. NOTICE Check the links frequently for wear.
Check that the chains do not contact
the wheel-arch liner at full lock.
See section ”Specifications”,
page 260, for information on allowable
wheel dimensions for the fitting of tire
chains.

192 Car care and technical informationBattery
The battery is provided with a cover to pro-
tect it from radiated heat. If the battery is
exposed to high temperatures, its life will be
shortened. To remove the cover, release
the two clips along its long sides.
The cover fits the standard battery installed
in the car. If a new battery is to be fitted,
make sure that its dimensions are the same
as the standard one.
The battery is maintenance free and should
be changed if the electrolyte level is too low.
The indicator on the top side of the battery
will be white if the battery needs replacing.
The fluid level and the charge level should
be checked regularly.
If frequent short journeys are made, the bat-
tery may need to be given a booster charge.
This can be done either using a battery
charger or by taking the car for a long run.
A car with a standard equipment specifica-
tion and a fully charged battery can be left
for up to 40 days and still have a sufficient
charge for starting. If extra equipment is fit-
ted, such as a car phone, the charge may
only be sufficient for about 15 days.
WARNING
Work on the battery may entail an
explosion hazard, since the battery
gives off hydrogen which forms an
explosive mixture with the oxygen in
the air.
For this reason, always avoid sparks
or open flames when working near the
battery.
The battery contains corrosive sulfuric
acid. Always wear a face mask or
goggles when working on the battery.
If battery acid gets into the eyes or
splashes the skin or clothing, wash the
affected area liberally with water.
If acid gets into the eyes or a large
quantity makes contact with the skin,
seek medical help.
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash your hands after
handling.
NOTICEA discharged battery can freeze and frac-
ture. Batteries should therefore always be
stored away from frost.
