2000 SAAB 9-5 overheating

48 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 175).
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.
The 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.
CHECK message indicator
This light indicates that there is a message
in the SID. A chime will also sound
(see page 58).
Central warning light
This light will come 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 audible alarm are also acti-
vated if the ignition key is turned to the ON
position and the engine is not started within
10 seconds.
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.

49 Instruments and controls

Engine malfunction
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 (see page
132).
Indicator, fuel
This light comes on when there is less than
about 2.5 gallons (10 liters) of fuel left in the
tank.
Indicator, cruise control
This light shows when the cruise-control
system is active (see page 145).
Indicator, high beam
This light shows when the headlights are on
high beam (see page 61).
Indicator, rear fog light
This light shows when the rear fog light is on
(see page 62).
The rear fog light is switched off automat-
ically when the engine is switched off. When
the fog light is next needed, it will have to be
switched on manually again.
The rear fog light consists of one light so it
should not be mistaken for rear light.
Indicator, open door
If a door has not been closed properly, the
pictogram will indicate the door concerned
(or tailgate).
WARNING
An illuminated “Engine malfunction” indi-
cator light indicates a serious
engine-related problem. While your car
may be able to be driven with the “Engine
malfunction” indicator light illuminated
(Limp-home mode), you are advised to
have your car serviced at a qualified facil-
ity 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.).
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.

141 Starting and driving
Overheated transmission fluid If the automatic-transmission fluid should
overheat, the following message will appear
on the SID:
”TRANSMISSION OVERHEATING”. If this
happens, stop the car and wait for the mes-
sage to be extinguished. Continue driving in
a locked gear that produces an engine
speed of about 3,000 rpm.
Overheating of the automatic-transmission
fluid can occur when the car is towing a
heavy load, such as a camping 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 temperature of the transmis-
sion fluid or the oil cooler may be faulty.
Contact an authorized Saab dealer (see
also page 152).
Towing Towing of cars with automatic transmission,
see page 158.
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!

143 Starting and driving
If 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.
Adaptive gear-change patternsAdaptive gear-change patterns are selected automatically depend-
ing on the engine load and the present temperature of the transmis-
sion. The function is available in Normal and Sport modes.
The changes occur at a higher engine speed and the car remains in
the same gear for longer, if the transmission control module senses
that the load has not decreased. These gear-change patterns pre-
vent unnecessary changing up and down, when for example driving
up long slopes with a trailer or caravan, and to prevent overheating
the transmission oil. The adaptive gear-change function is also
selected automatically when the transmission oil becomes too hot,
to protect the transmission itself from serious damage and to lower
the oil temperature.
The adaptive gear-change pattern function is deselected when:
 Winter mode is selected.
 The engine is switched off.
 The load is reduced so much that the function is no longer
required.
 “Fault indicator, automatic transmission” appears on main
instrument panel, see page 140. 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 37 mph (60 km/h).

153 Starting and driving
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 104°F (40°C).
When negotiating long hills, bear the follow-
ing important considerations in mind:
If TRANSMISSION OVERHEATING
appears on the SID, stop the car as soon as
it is safe to do so and wait until the warning
has been extinguished. When continuing
your journey, select a locked gear (1, 2 or 3)
that will allow you to drive at an engine
speed of about 3,000 rpm (see page 142).
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.
Trailer hitch loadThe weight distribution on the trailer makes
a lot of difference to the handling properties
of the car and trailer combination. As
regards single-axle trailers, whenever pos-
sible, concentrate the load over the wheels
and keep it as low as possible.
The trailer should be loaded so that the
maximum load on the towbar ball is 5% to
7% of the trailer weight with a maximum per-
missible tongue weight of 165 lbs. (75 kg).
Note that this load must be added to the total
load for the car. If this now exceeds the
specified load capacity, the load in the lug-
gage compartment will have to be reduced
by a corresponding amount. Driving considerations Always take extra care when towing a
trailer, as the car’s handling will be different
and its braking effect reduced. The trailer’s
braking system and suspension also have a
considerable effect on these characteris-
tics.
If the car is equipped with automatic trans-
mission, select position 1 when ascending
or descending steep hills. Gradient

mission” indicator comes on, cease
towing until the problem has been recti-
fied.
