61 Instruments and controls
Speedometer
(U.S. speedometer shown)The speedometer receives signals from the
wheel sensors in the ABS system.
If the NIGHT PANEL mode has been
selected, the scale will be illuminated up to
87 mph (140 km/h). The remainder of the
scale will be illuminated if the speed of the
car exceeds 84 mph (135 km/h).
Fuel gauge Fuel-tank capacity, 18.5 US gal. (70 liters).
The fuel gauge shows the amount of fuel left
in the tank. When this is down to about
2.5 gal. (10 liters), a warning light on the
main instrument panel will come on (see
page 57).
Use the Saab Information display (SID) to
check the approximate distance that can be
traveled on the remaining fuel
(see page 63).
Temperature gauge The temperature gauge shows the temper-
ature of the coolant. The needle should be
in the middle of the scale when the engine
is at normal operating temperature.
If the needle approaches the red zone,
which can occur in very hot weather or when
the engine is under a heavy load, drive in the
highest gear possible, keep the engine revs
low and avoid shifting down.
If the needle enters the red zone, the
warning light will come on and an alarm
chime will sound.

136 Interior equipment and trunk
WARNING
 Place heavy items closest to the backrest and stow smaller
and lighter items on top.
Never overload the cargo net. If the elastic breaks this may
cause personal injury. Do not use a cargo net that shows signs
of wear.
 Secure heavy and bulky items using the tie down points
provided in the trunk. This will avert the danger of luggage
flying around if the car should brake suddenly or be involved
in a crash (see page 137).
 Secure small items if the backrest is folded down or the
load-through hatch is open. Small items can also be thrown
around inside the car and cause personal injury.
 Do not exceed the load capacity of the car, as this will alter its
handling characteristics (see page 270).
 Make sure that the seat cushions and backrests are properly
secured when folding them back to their normal position.
Check that the button (item 3 on page 135) is flush with the
surround before entering the back seat.
The tail pipe of the exhaust system can become very hot during
driving. Bear this in mind when loading and unloading the car so
that children, for example, do not burn themselves.

137 Interior equipment and trunk
Trunk pass-through hatch A trunk pass-through hatch is incorporated in the rear seat backrest
to enable long, narrow items to be carried inside the car.
Items should not weigh more than 33 lbs. (15 kg) nor be more than
2 yards (2 metres) in length. See the label on the hatch.
1 Fold down the armrest.
2 Raise the hatch by lifting the handle.
Before loading or unloading long items, switch off the engine and
apply the handbrake. This averts the danger of the car moving off
suddenly if a long item were to knock the gear or selector lever into
gear. Tie DownsThe tie downs for securing the load are fitted inside the trunk. Place
the load as far in as possible.
WARNING
 Anchor the load securely (e.g. using middle safety belt) to
avoid danger of injury resulting from displacement of load on
hard braking.
 Do not exceed the load capacity of the car, as this will alter its
handling characteristics (see page 270).

151 Starting and driving
Limp-home modeThe engine management system has a
diagnostic feature that continually checks a
number of internal functions. If, for example,
a fault is detected in the throttle valve, the
engine management system will go into
Limp-home mode.This limits idling control,
disables the cruise-control system and
limits the capacity of the A/C compressor.
If the limp-home mode is in operation
(”Engine malfunction (CHECK ENGINE)”
light on, see below) and the outside temper-
ature is close to or below freezing, you may
need to use some throttle on starting (some
pressure on the accelerator).
If the diagnostic system has detected a fault
in the engine-management system, the
”Engine malfunction (CHECK ENGINE)”
light on the main instrument panel will
come on (see page 57), indicating that you
should have the car checked as soon as
possible by an authorized Saab dealer.
Important
considerations for
drivingThe engine-management system in the
Saab 9-5 is called Saab Trionic T7. The
system manages the ignition, fuel injection
and turbo boost pressure.
The Trionic T7 system developed by Saab
is an intelligent engine-management
system designed to achieve optimum driv-
ability under differing driving conditions.
The system makes adjustments automati-
cally, for instance, if the car is being driven
at altitude (oxygen-deficient air), for differ-
ent grades of fuel (AON 87–93) and for dif-
ferent load conditions.
1 Starting and driving
 Refrain from using full throttle before
the engine has warmed up (before
needle in mid-range on temperature
gauge).
 A safety function prevents the engine
from revving faster than 6,000 rpm by
limiting the induction air.
2 Stopping the engine
 Do not rev the engine immediately
before switching it off – stop the engine
when it is idling.
3 Regulating the boost pressure
 The system is optimized for fuel with an
octane rating of AON 90. The 2.3 Turbo
and 2.3 T are optimized for AON 93.
NOTICEIf the CHECK ENGINE warning light
starts to flash, ease off the accelerator
slightly. If the light does not cease to flash
within 5 seconds, stop the car in a suit-
able place as soon as possible and turn
off the engine. The car must be towed to
an authorized Saab dealer.
If the CHECK ENGINE warning light
flashes, it indicates that the engine is mis-
firing which can result in damage to the
catalytic converter.

182 Starting and drivingTrailer 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
permissible tongue weight of 110–165 lbs.
(50–75 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.
WARNING
When you connect the trailer be sure to
attach its safety chains to the holes as
illustrated.

238 Car care and technical informationWheel Alignment and Tire Balance
The wheels on your vehicle were aligned
and balanced carefully at the factory to give
you the longest tire life and best overall per-
formance.
Scheduled wheel alignment and wheel bal-
ancing are not needed. However, if you
notice unusual tire wear or your vehicle pull-
ing one way or the other, the alignment may
need to be reset. If you notice your vehicle
vibrating when driving on a smooth road,
your wheels may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or
badly rusted or corroded. If wheel nuts keep
coming loose, the wheel, wheel bolts and
wheel nuts should be replaced. If the wheel
leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired).
See your dealer if any of these conditions
exist.
Your dealer will know the kind of wheel you
need.
Each new wheel should have the same
load-carrying capacity, diameter, width,
offset and be mounted the same way as the
one it replaces.
If you need to replace any of your wheels,
wheel bolts or wheel nuts, replace them only
with new Saab original equipment parts.
This way, you will be sure to have the right
wheel, wheel bolts and wheel nuts for your
vehicle.
Notice:
The wrong wheel can also cause
problems with bearing life, brake cool-
ing, speedometer or odometer calibra-
tion, headlamp aim, bumper height, vehi-
cle ground clearance and tire or tire
chain clearance to the body and chassis.
See “Changing a wheel” on page 247.Used Replacement Wheels
WARNING
Using the wrong replacement wheels,
wheel bolts or wheel nuts on your vehicle
can be dangerous. It could affect the
braking and handling of your vehicle,
make your tires lose air and make you
lose control. You could have a collision in
which you or others could be injured.
Always use the correct wheel, wheel bolts
and wheel nuts for replacement.
WARNING
When fitting just one new pair of tires,
these should be fitted to the rear wheels,
as these are more critical to the direc-
tional stability of the car (e.g. on braking
or in a skid). The existing rear wheels
should therefore be moved to the front.
WARNING
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been
used or how far it’s been driven. It could
fail suddenly and cause a crash. If you
have to replace a wheel, use a new GM
original equipment wheel.

244 Car care and technical informationSteps for Determining Correct Load
Limit
1 Locate the statement “The
combined weight of occupants and
cargo should never exceed
XXX pounds” on your vehicle´s
placard.
2 Determine the combined weight of
the driver and passengers that will
be riding in your vehicle.
3 Substract the combined weight of
the driver and passengers from
XXX kilograms or XXX pounds.
4 The resulting figure equals the avail-
able amount of cargo and luggage
load capacity. For example, if the
“XXX” amount equals 1400 lbs. and
there will be five 150 lb. passengers
in your vehicle, the amount of avail-
able cargo and luggage load capac-
ity is 650 lbs. (1400–750 (5x150) =
650 lbs.).5 Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calcu-
lated in Step 4.
6 If your vehicle will be towing a trailer,
load from your trailer will be trans-
ferred to your vehicle. Consult this
manual to determine how this
reduces the available cargo and
luggage load capacity of your vehi-
cle.Winter tires
Winter (snow) tires are recommended for
winter climates where the majority of your
driving will be done on snow and ice. Winter
tires should be fitted to all four wheels to
maintain a proper balance. Your Saab
dealer can advise you of to the correct size
tire for your car (if different from the original
size) and also supply Saab approved winter
tires pre-mounted on steel or alloy rims.
