2000 SAAB 9-3 overheating

56 Instruments and controls
Anti-lock brake warning
This light together with and indi-
cates that a fault has occurred in the ABS
system. Conventional braking without the
ABS function will still be available.
For safety reasons, stop the car and check
the level of the brake fluid (see page 176).
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 authorized Saab dealer
to have the brake system checked.

Airbag warning light
This light together with will come on if
a potentially serious fault has occurred in
the airbag system.
This light will come on for about three sec-
onds when the ignition switch is turned to
the Start or Drive position. It should go out
after the engine has started.

Indicator, fuel
This light comes on when there is less than
about 2.5 gallons (10 litre) of fuel left in the
tank.
WARNING
 If the ABS is inoperative, there is a
danger of the rear wheels locking up
on hard braking
 If the level of brake fluid in the reser-
voir is below the MIN mark, the car
should be towed to an authorized
Saab dealer
WARNING
 If the airbag readiness light stays on
after you start your vehicle, it means
the airbag system may not be working
properly.
 The airbags in your vehicle may not
inflate in a crash, or they could even
inflate without a crash.
 To help avoid injury to yourself or
others, have your vehicle serviced
right away if the airbag readiness light
stays on after you start your vehicle.
NOTEIf the car runs out of fuel, air can have
been drawn in with the fuel, which, in turn,
can cause the catalytic converter to be
damaged by overheating.

57 Instruments and controls
Central warning light
This light comes on and a chime will sound
if a fault has been detected in any system
that is critical to safety. Any of the following
can activate the central warning light and
alarm:
 Airbag system.
 Low oil pressure in engine.
 Parking brake is on (when car is moving).
 Brake fluid level low.
 Fault detected in ABS system.
 Engine overheating.
 Alternator not charging properly.
The symbol and the chime will also sound if
the ignition key is turned to the ON position
but the engine is not started within 10 sec-
onds.
Cruise Control
indicator light
The symbol is lit when cruise control is
active.
Engine malfunction
(CHECK ENGINE)
This light indicates a malfunction in the
fuel-injection or ignition system. The car
may still be driven with care and with some-
what diminished performance.
SPORT Mode Indicator
On cars with automatic transmission the
indicator light comes on when you press the
SPORT button on the gear-lever knob.
In SPORT mode, the transmission remains
longer in the (D, 3, 2, 1) gears before
upshifting.
Quit Sport mode by again depressing the
SPORT button; see also page 147.
WINTER Mode Indicator
On cars with automatic transmission the
indicator light comes on when, in the D posi-
tion, you press the WINTER button on the
center console next to the gear selector.
When the car is in the Winter mode it starts
in 3rd gear, which gives a better grip in
slippery conditions by reducing the ten-
dency to spin the wheels.
Quit Winter mode by again depressing the
WINTER button; see also page 147.
WARNING
An illuminated CHECK ENGINE indicator
light indicates a serious engine-related
problem. While your car may be able to be
driven with the CHECK ENGINE indicator
light illuminated (limp-home mode), you
are advised to have your car serviced at
an authorized Saab dealer as soon as
possible.
Continued driving without this problem
being corrected might cause serious fur-
ther damage to your car and create
unsafe driving conditions. The operator
should be prepared to take action if such
unsafe conditions arise (e.g., apply the
brakes, disengage transmission, turn off
the ignition etc.).

144 Starting and driving
Automatic transmission
fault indicator
If the symbol appears on the main instru-
ment panel, the system has detected a fault
in the automatic transmission or its control
module (see page 58).
This also means that the Limp-home mode
has been selected, to guard against further
damage being done to the transmission. In
this mode, the automatic transmission
starts in 4th gear, and gear changes (if nec-
essary) will have to be made manually.
It is not possible to select the SPORT or
WINTER mode when the Limp-home mode
is active.
You should have the automatic transmis-
sion checked as soon as possible by an
authorized Saab dealer.
The following gears will be engaged in the
respective selector positions when the auto-
matic transmission is in the Limp-home
mode:
Overheated transmission oilIf the transmission oil becomes overheated
while driving, the following message
appears on the SID: TRANSMISSION
OVERHEATING. In this event, stop the car
in a suitable place, switch off the engine,
open the hood and wait until the message
goes out. When driving subsequent to the
transmission oil overheating, select a
locked gear position in which the engine
speed is about 3,000 rpm.
The transmission oil can become very hot
when the car is driven with a heavy load; for
example, driving with a trailer on hilly roads
when the wrong gear has been selected,
resulting in many extra gear changes.
Select one of the positions 1, 2 or 3. A high
outside temperature or a defective oil cooler
can also cause the oil temperature to
increase. Contact an authorized Saab work-
shop, see also page 156.
Driving in hilly country with a heavy
loadOverheating of the automatic-transmission
fluid can occur when the car is towing a
heavy load, such as a trailer in hilly country,
with the wrong gear selected, resulting in
abnormally frequent gear changing. Try
selecting position 1, 2 or 3. High ambient
temperatures can also increase the temper-
ature of the transmission fluid or the oil
cooler may be faulty. As the transmission
fluid temperature increases, its useful ser-
vice life is reduced. Contact an authorized
Saab dealer (see also page 156).TowingTowing a car with automatic transmission,
see page 162. Position R D 3 2 1
Gear Reverse 4th 4th 3rd 3rd
NOTEIf the control module has actuated the
Limp-home function for the automatic
transmission, the car will remain in 4th
gear when D is selected, making it very
sluggish. To overcome this, move the
selector lever to position 2.
WARNING
Remember to use engine-braking (selec-
tor position 1, 2, or 3) to spare the brakes
when you are driving on a long or steep
downhill slope. Select the same gear as
you would on the corresponding uphill
slope.
Brake failure can result from overheated
brakes!

146 Starting and drivingIf the gear selector lever is moved from position D to 1, a
change-down to 3rd gear will occur at about 110 mph (180 km/h).
A change-down to 2nd gear will occur at about 75 mph (120 km/h)
and to 1st gear at about 40 mph (65 km/h).
When position 1 is selected, all the other gears will be locked out.
Manual gear-changing is not recommended on slippery roads.
2.0 Turbo 185 hp and 205 hp: If one of the drive wheels spins
excessively, the engine torque will be reduced to avoid damaging
the transmissionKick-downWhen the accelerator is pressed down hard, a downshift to the next
lower gear will occur to provide maximum acceleration, e.g. for over-
taking.
The change-up to the next gear again will take place either when the
accelerator is released or when maximum engine speed for that
gear is reached.
Adaptive gear-change patternsAdaptive gear-change patterns are selected automatically depend-
ing on the engine load. This function applies in the Normal and Sport
modes.
The change occurs at a higher rotation speed and the gear remains
engaged for a longer period, if the control module senses that the
load does not drop. These change patterns avoid unnecessary gear
changes when, for example, driving on long inclines with a trailer,
and to prevent overheating of the transmission oil. This function cuts
in automatically if the oil becomes too hot, to protect the transmis-
sion from serious damage, and lower the oil temperature.
The adaptive change pattern function is not activated at speeds over
93 mph (150 km/h). If a pattern is in operation when this speed is
exceeded, it will be maintained until the control module senses that
a more suitable one can be activated.
The adaptive gear-change pattern function is deselected when:
 Winter mode is selected.
 The engine is switched off.
 The load is reduced by so much that this function is no longer
required.
 “Automatic transmission fault indicator” appears on the
main instrument panel, see page 144. 1
Position 1 should be used when maximum
engine-braking is required on steep downhill
slopes and to avoid frequent gear-changing on
steep climbs.
Do not move the selector to position 1 at speeds
in excess of 30 mph (50 km/h).

149 Starting and driving
Disengaging the system The system will be disengaged:
 When the brake or clutch pedal is
depressed.
 When the switch is moved to CANCEL.
 When the switch is moved to OFF.
 When the engine is switched off.
 When the selector lever is moved to posi-
tion N (cars with automatic transmission).
BrakingTo avoid overheating the brakes, (e.g. when
negotiating long descents with a drop of
several hundred feet), select a low gear to
use the braking effect of the engine. If the
car has automatic transmission, move the
selector lever to position 1 or 2.
When driving fast, you can help to prolong
the life of the brakes by thinking ahead and
braking harder for short periods, rather than
braking more moderately over long
stretches. Brake pad wear indicatorsThe outboard brake pads on the front
wheels incorporate pad-wear indicators.
When the lining is down to 3 mm, the pad
will produce a screeching, squealing or
scraping noise when the brakes are applied.
New pads should be installed without delay.
Brake pads should only be replaced by
an authorized Saab dealer.
To ensure optimum brake performance,
it is recommended that you use only
Saab original brake pads.

WARNING
 It is prudent to try your brakes from
time to time, especially when driving in
heavy rain, on roads with a lot of sur-
face water, or in snow or slush. In such
conditions, the brakes may take
longer than normal to take effect. To
rectify this, touch the brake pedal peri-
odically to dry the brakes out.
 The same applies after the car has
been washed or when the weather is
very humid.
 The brakes are power assisted and it
should be kept in mind that the servo
unit only provides the power assis-
tance when the engine is running.
 The brake pressure required when the
engine is off,( e.g. when the car is
being towed) is roughly four times the
normal pedal force required. The
pedal also feels hard and unrespon-
sive.

157 Starting and driving
Trailer weightMaximum recommended trailer weights for
different gradients, for best comfort and
driveability for manual and automatic cars,
are shown in the drawing.
Make sure you are familiar with the law
regarding speed limits for towing, maxi-
mum trailer weights, trailer-braking
requirements, and also any special
driving-license provisions
(see also page 222).
The specified trailer weights and gradients
assume you are operating in hilly terrain and
therefore apply only to short trips.Recommendations for cars with auto-
matic transmission
The following time limits are based on the
capacity of the cooling system in warm
weather, i.e. approximately 86°F (30°C).
The following time limits are based on the
capacity of the cooling system in warm
weather, i.e. approximately 104°F (40°C).
When negotiating long hills, bear the follow-
ing important considerations in mind:
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.
NOTESaab 9-3 Viggen cannot be equipped
with a trailer hitch because of the design
of the body and chassis.
WARNING
When towing a trailer, do not attempt to
negotiate a hill having a gradient in
excess of 15%. The weight distribution
over the front wheels of the car will be
insufficient to prevent wheelspin, making
further progress impossible.
In addition, the parking brake may not
always be able to hold the car and trailer
securely, with the result that the wheels
can start to slide downhill.
