56 Instruments and controlsThis light indicates when the front fog lights
are on (see page 74).
The front fog lights are switched off auto-
matically when the engine is switched off.
When the fog lights are next needed, they
will have to be switched on manually.
This light indicates when the rear fog light is
on (see page 74).
The rear fog light is switched off automati-
cally when the engine is switched off. When
the fog light is next needed, it will have to be
switched on manually again.This light should come on briefly when you
turn the ignition key to ON. If it doesn´t come
on, have it fixed so it will be ready to warn
you if there is a problem. This light indicates
when the brake fluid level is too low (see
page 180).
The following message is shown on the
Saab Information Display (SID):For safety reasons, stop the car and check
the level of the brake fluid (see page 180).
If the level is normal, depress the brake
pedal firmly two or three times. Now check
the level again. If the level is still normal, you
may drive the car, with considerable cau-
tion, to the nearest Saab dealer to have the
brake system checked.
The brake system provides Electronic
Brakeforce Distribution (EBD). This distrib-
utes the brake pressure between the front
and rear wheels, in such a way as to achieve
optimum braking performance irrespective
of the car’s load.
If a fault arises in the EBD function, the ,
and lights will come on. Also, the fol-
lowing message will appear on the Saab
Information Display (SID):
If this is the case, drive carefully and contact
a Saab dealer as soon as possible. Refer to
Brake warning light on page 56, Antilock
braking warning on page 54 and TCS OFF
or ESP OFF indicator (certain variants only)
on page 63.

 If the level of brake fluid in the reser-
voir is below the MIN mark, the vehicle
should be transported on a recovery
vehicle.

135 Starting and driving
Park Brake Shift LockThe transmission has a security function
known as Park Brake Shift Lock. To move
the gear selector lever out of the P or N posi-
tion, the gear selector lever detent (catch)
must be pressed in at the same time as the
brake pedal is held depressed.
The detent button on the selector lever has
to be pressed in before the lever can be
moved between certain positions.
Temporary override of Park Brake Shift
Lock, see page 137.
Adaptive gear change patternsThe adaptive gear change pattern function
adapts gear changing to the prevailing driv-
ing conditions. The transmission control
module senses the engine load, vehicle
speed and temperature of the transmission.
A suitable gear change pattern is then
selected automatically to avoid unneces-
sary gear changes and undesired increases
in transmission temperature.
Certain variants use a special change pat-
tern for the first few minutes after a cold start
so that the catalytic converter reaches its
working temperature more quickly.
Thermal transmission protectionThe transmission has built-in protection
against overheating. This protection is pro-
vided by the control module, which changes
gear change patterns.
1 If the temperature of the transmission
fluid exceeds 257°F (125°C), the gear
change pattern is changed.
2 If the temperature of the transmission
fluid exceeds 275°F (135°C), the gear
change pattern is again changed.
3 If the temperature of the transmission
fluid exceeds 302°F (150°C), engine
torque will be limited to 147 ft.lbs.
(200 Nm).
The following message is shown on the SID:
If this message appears, stop the car as
soon as it is safe to do so and allow the
engine to idle until the message has gone
out. The selector lever should be in
position P.Gearbox too hot.
Make a safe stop.
Open hood to cool down.

136 Starting and drivingLock-upThe transmission’s torque converter has a
lock-up function. This can lock the torque
converter in 3rd, 4th and 5th gears, thus
reducing the engine speed and fuel con-
sumption.Kick-downWhen the accelerator is pressed down fully,
a down change is made to optimize acceler-
ation, e.g. for overtaking.
Following this, the next higher gear will be
selected at the optimum engine speed,
unless you ease off the accelerator before
reaching this. Kick-down works in manual
mode in 4th and 5th gears if the engine
speed is lower than 2,000 rpm.
Driving in hilly country with a heavy
loadThe transmission fluid can overheat when
the gearbox is strained, for example, when
driving with a trailer on hilly roads. To avoid
the transmission fluid overheating, always
drive with the selector lever in the D posi-
tion. The adaptive gear change patterns are
then active.
High air temperatures or a faulty oil cooler
can also cause the transmission fluid to
overheat. Overheating reduces the service
life of the fluid.TowingTowing of cars with automatic transmission,
see page 164.
Descending hillsIf the speed of the car increases while
descending a steep hill, despite the acceler-
ator being released, the control module will
change down to 4th gear. If you desire more
powerful engine braking, manually select a
lower gear (see page 139).
WARNING
Remember to use the braking effect of the
engine (1st, 2nd or 3rd gear) when you
are descending long or steep hills to
spare the brakes.
Overheating can cause the brakes to
fade!

150 Starting and drivingLong-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!
If necessary, use wheel chocks.
 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.

170 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
wheel.
 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.

180 Car careNote:
If incorrect coolant is used or added, the life-
time properties will be affected. Even if the
coolant is flushed from the system and
replaced with life-time coolant, life-time
properties are no longer retained and the
coolant must then be drained and replaced
at regular intervals.
Brake/clutch fluid and
brake padsCheckingBrake fluid should be changed according to
the service program. Refer to the Warranty
and Service Book.
The brake and clutch fluid reservoir is trans-
parent to facilitate checking of the fluid level.
The fluid level should lie between the MAX
and MIN marks.
Top up as necessary with DOT 4 brake
fluid. Do not use DOT 5 fluid.
Use only new brake fluid from a sealed
container.
The brake fluid level will fall somewhat as
the brake pads wear. The MAX level in the
reservoir corresponds to the amount of
brake fluid required with new brake pads. If
the fall in fluid level is moderate, due to
normal brake pad wear, topping up is not
necessary.If the brake fluid should require chang-
ing, this must be carried out at a Saab
dealer.
NOTICEIf the cooling system needs topping up,
mix the antifreeze with the appropriate
quantity of drinking water or distilled
water before adding it to the system.
If undiluted antifreeze is added, the
engine could still freeze and be damaged.
This is because the antifreeze will not mix
properly with the coolant before the ther-
mostat has opened to allow full circula-
tion.
WARNING
Brake fluid deteriorates as it becomes
old. Because it is hygroscopic, it absorbs
water from the air and, in time, could allow
vapor to form in the brake system, thus
reducing its performance. It is therefore
important that brake fluid be changed
regularly, as specified in the service
program.

181 Car care
The foot brake and parking brake are self-
adjusting.
It is not possible to detect, through abnormal
pedal or parking brake lever travel, whether
the brake pads are worn and need replac-
ing. It is therefore essential that brake pads
be checked regularly, as specified in the
service program.
Brake pads should only be changed at a
Saab dealer. To ensure optimum brake
performance, use only Saab genuine
brake pads.
Power steeringCheck the level of the power steering fluid in
the reservoir regularly, in accordance with
the service program.
The wheels should point directly forwards
during this check.
Clean round the cap before unscrewing it.
Wipe the dipstick. To check the level, screw
down the cap completely and then remove
it again.
The oil level should lie between the MAX
and MIN marks when the oil temperature is
about 68°F (+20°C). If the oil is colder, the
level will be lower, and at a higher tempera-
tures the level will be higher, both of which
are acceptable.
Top up with "CHF 11S power steering fluid".
NOTICEAvoid spilling brake fluid onto paintwork,
since it can cause the paint to bubble and
lift. If any brake fluid is spilled, the area
should be flushed with large quantities of
water as quickly as possible.
WARNING
Power steering fluid on hot engine
components constitutes a fire risk.
