2005 SAAB 9-5 heating

147 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 161).
Towing Towing of cars with automatic transmission,
see page 171.
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!

150 Starting and drivingIf you move the selector lever from D to L, down shifts will follow a
set pattern to avoid damaging the engine or transmission.
Manual gear-changing is not recommended on slippery roads.
If one of the drive wheels spins excessively, the engine torque will
be reduced to avoid damaging the transmission.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 or down long slopes with a trailer or caravan, and to prevent over-
heating 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 damage and to lower the
oil temperature.
The adaptive gear-change pattern function is deselected when:
 The engine is switched off.
 The load is reduced so much that the function is no longer requi-
red.
 ”Automatic transmission, fault indicator” appears on main
instrument panel, see page 146.
SPORT modes
To select Sport mode, press the ”S” button on
the selector lever when the selector lever is in
position N or D.
In this mode, gear changes will take place at hig-
her engine speeds than in Normal mode, in
other words, the transmission will change up
later and change down earlier for the same
throttle (accelerator) position.
The Sport mode will be deselected if:
 The S button is pressed.
 The selector lever is moved to position P,R, M
or L.
 The engine is switched off.
 ”Automatic transmission, fault indicator”
appears on main instrument panel, see
page 146.

163 Starting and driving
When negotiating long hills, bear the follo-
wing important considerations in mind:
 Use Normal mode when driving with a
caravan or trailer on hilly roads. The adap-
tive gear change pattern function will pre-
vent the transmission overheating.
 Rises in coolant temperature are indica-
ted by the temperature gauge in the main
instrument panel.
Recommendations for cars with
automatic transmissionRises 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 149).
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!

212 Car care and technical informationMaxi fusesThe Maxi fuses are housed in the fuse box
under the hood. These fuses can be
checked in the same way as the other fuses.
The Maxi fuses are designed to protect the
car’s electrical system from being dama-
ged. Each Maxi fuse protects a number of
electrical circuits and functions and there-
fore has a higher rating (amperage) than the
standard fuses. No spare Maxi fuses are
supplied with the car.
DICE / TWICEDICE = Dashboard Integrated Central Elec-
tronics
TWICE = Theft-Warning Central Electronics
DICE and TWICE are electronic control
modules that monitor and control a variety
of functions, including:
DICE controls (among other things):
 Front lights and interior lighting
 Instrument illumination
 Intermittent wiper operation
 Electric heating of rear window and door
mirrors
 Cooling fans
TWICE controls (among other things):
 Central locking.
 Car alarm (Anti-theft system)
 Engine immobilizer
 Autochecking of lights.
 Electric heating of rear seat
 Safety belt reminder
 Electrically adjustable passenger seatThe DICE and TWICE control modules are
linked to a data bus, which is basically an
information carrier that allows information to
be exchanged between all the control
modules and components connected to the
bus.
If a fault occurs in any of these components,
diagnostic faults codes are set in the rele-
vant control module, which facilitates fault
diagnosis at the Saab dealer.
The scan tool connector for fault diagnosis
is located under the instrument panel on the
drivers side.
NOTICEIf a Maxi fuse blows, it means that there is
a major fault in the electrical system.
Have the car checked without delay by an
authorized Saab dealer.

217 Car care and technical information
Tires 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
vehicle 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 flexingToo much heatTire overloadingBad wearBad handlingBad fuel economy
If your tires have too much air (overinfla-
tion), you can get the following:Unusual wearBad handlingRough ride
Needless damage from road hazards
Adjust the tire pressure to match the current
load and speed of the car (see page 261).
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 226.
 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
pothole. Keep tires at the recom-
mended pressure.
 Worn, old tires can cause accidents. If
your tread is badly worn, or if your tires
have been damaged, replace them.
