2009 SAAB 9-5 overheating

61 Instruments and controls
This light 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.This light comes on when there is less than
about 2.5 gallons (10 liters) of fuel left in the
tank. This light indicates that there is a fault in the
Xenon headlight system, which consists of
xenon headlights and an automatic levelling
system.
If a fault arises in the Xenon headlight sys-
tem, the headlights will be angled down to
avoid impairing the vision of drivers in
oncoming traffic. Adjust your speed accord-
ingly as visibility will be reduced.
Airbag warning light
WARNING
 If the airbag readiness light stays on
after you start your vehicle, it means
the airbag system may not be working
properly.
 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.
Indicator, fuel
NOTICE
If the car runs out of fuel, air can be drawn
in with the fuel, which, in turn, can cause
the catalytic converter to be damaged by
overheating.
Xenon headlight fault
indicator3
NOTICE
If the Xenon headlight fault indicator lights
up, have your car checked as soon as
possible a workshop. We recommend
that you contact an authorized Saab
dealer.
If you do not rectify the problem, nighttime
visibility will be poor since the range of the
headlights is reduced.

120 Interior equipment and trunkGate Operator / Canadian Programming
Canadian radio-frequency laws require
transmitter signals to "time-out" (or quit)
after several seconds of transmission -
which may not be long enough for the
garage opener to pick up the signal during
programming. Similar to this Canadian law,
some U.S. gate operators are designed to
"time-out" in the same manner.
If you live in Canada or you are having diffi-
culties programming a gate operator by
using the "Programming" procedures
(regardless of where you live), replace
"Programming " step 4 with the following:
Note: If programming a garage door opener
or gate operator, it is advised to unplug the
device during the "cycling" process to pre-
vent possible overheating.
Continue to press and hold the button while
you press and release - every two sec-
onds ("cycle") your hand-held transmitter
until the frequency signal has successfully
been accepted by the garage opener. (The
indicator light will flash slowly and then rap-
idly.)
Proceed with "Programming" step five to
complete.Reprogramming a single button
To program a device to the garage opener
using a button previously trained, follow
these steps:
1 Press and hold the desired button. DO
NOT release the button.
2 The indicator light will begin to flash after
20 seconds. Without releasing the
button, proceed with "Programming" -
step 3.Erasing the three buttons
To erase programming from the three but-
tons (individual buttons cannot be erased
but can be "reprogrammed" as outlined
below), follow the step noted:
 Press and hold the two outer buttons until
the indicator light begins to flash-after
20 seconds. Release both buttons. Do
not hold for longer that 30 seconds. The
garage opener is now in the train (or
learning) mode and can be programmed
at any time beginning with "Programming"
- step 3.
NOTICESwitch off the power supply to the garage
door or gate (or park the car beyond the
range of the remote control) while pro-
gramming using the "cycling" method to
prevent damaging the electrical motor.

154 Starting and drivingIf ”Automatic transmission3, fault indicator”
light appears on the main instrument panel,
the system has detected a fault in the auto-
matic transmission or its control module
(see page 62).
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 5th gear, and gear changes (if nec-
essary) will have to be made manually.
Stop the car in a safe place. Switch off then
restart the engine. If the fault is intermittent,
the transmission will operate as normal
despite the fault indicator being on. Have
the car checked at a workshop. We recom-
mend that you contact an authorized Saab
dealer.
It is not possible to select the SPORT or
Sentronic mode when the Limp-home mode
is active.
Gear changes must be made manually.
The following gears will be engaged in the
respective selector positions when the auto-
matic transmission is in Limp-home mode:
Overheated transmission fluid If the automatic-transmission fluid should
overheat, the following message will appear
on the SID:
”Gearbox too hot.
Make a safe stop.”
In this event, stop the car in a suitable place,
switch off the engine and open the hood.
Wait for several minutes then turn on the
ignition to check that the message has gone
out. When driving subsequent to the trans-
mission fluid overheating, select a gear in
which the engine speed is 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. High ambient temperatures can
also increase the temperature of the trans-
mission fluid or the oil cooler may be faulty.
Contact a workshop. We recommend that
you contact an authorized Saab dealer (see
also page 174).
Automatic transmission3,
fault indicator
Position R D M L
Gear Reverse 5th 5th 2nd
NOTICEIf the control module has actuated the
Limp-home function for the automatic
transmission, the car will remain in 5th
gear when D is selected, making it very
sluggish.
Select position L to prevent unnecessary
wear on the transmission. The transmis-
sion then starts in 2nd gear. Once the car
is moving you can select position D.
When the indicator light is on, the car
must not be driven with a caravan or
trailer attached.

155 Starting and driving
Driving on hilly roads 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 in Normal mode. 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. Contact an authorized Saab
dealer (see also page 174).
Towing Towing of cars with automatic transmission,
see page 181.
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 a gear when you brake. If you
desire more powerful engine braking, man-
ually select a lower gear.
WARNING
Remember to use engine-braking (selec-
tor position D or L) to spare the brakes
when you are driving on a long or steep
downhill slope.
Brake failure can result from overheated
brakes!

176 Starting and drivingWhen negotiating long hills, bear the follow-
ing important considerations in mind:
 Use Normal mode when driving with a
caravan or trailer on hilly roads. The
adaptive gear change pattern function will
prevent the transmission overheating.
 Rises in coolant temperature are indi-
cated by the temperature gauge in the
main instrument panel.Recommendations for cars with
automatic transmission
Rises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
The following steps are taken in order as the
temperature of the engine increases:
 Gear change pattern is altered.
 A/C compressor is switched off.
 Engine torque is reduced.
The following message will be displayed on
the SID if the transmission fluid becomes
too hot:
“Gearbox too hot.
Make a safe stop.“
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.When continuing your journey, select
manual mode and a gear in which the
engine speed is about 3,000 rpm until the
incline eases (see page 157).
WARNING
Remember to use the braking effect of the
engine (position D or L) when you are
descending long or steep hills to spare
the brakes.
Brake failure can result from overheated
brakes!

220 Car care and technical informationTires Your 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 263).
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
Poorly 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 229.
 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 pot-
hole. Keep tires at the recommended
pressure.
 Worn, old tires can cause accidents. If
your tread is badly worn, or if your tires
have been damaged, replace them.95_US_MY09.book Page 220 Tuesday, April 15, 2008 11:03 AM
