254 Car careThe system does not warn if the tire pres-
sure is too high.
If the system has warned or triggered an
alarm due to inadequate pressure then
the pressure must be reset to the recom-
mended pressure so that the warning/alarm
is cleared.If the tire pressure decreasesIf the tire pressure decreases to 6 psi
(40 kPa) below the recommended pressure
then a warning is shown on the SID as to
which tires are affected.
Adjust the pressure as soon as possible. If the tire pressure continues to decrease
then an alarm is shown on the SID when the
pressure has decreased to 23 psi (160 kPa)
which is the lowest permitted pressure for
the tire.
An alarm is also received when leakage is
greater than 3 psi/min. (20 kPa/min.).
Reduce speed (avoid heavy braking and
significant steering wheel movement) and
stop the car as soon as possible at a suita-
ble location. Replace the defective wheel.
The fault message can remain for up to
10 minutes after restarting the car. Then it
disappears if the tire pressure is correct.Check/adjust the pressure in the other tires
when a fault message is shown.
Note that the tire pressure can decrease
without a puncture. The pressure could
decrease around 3 psi (20 kPa) during a
three month period.
The outside temperature could also affect
tire pressure.
The temperature in the
tire also affects the
tire pressure. The spec ified tyre pressures
are valid for cold tyres. The increased tyre
pressure resulting from extensive driving
must not be reduced. For further informa-
tion on tire air pressure , see page 240.
Allow 10 minutes for the system to recog-
nize the wheel/sensors positions after fitting
a new set of tires. During this period no low
pressure warning or alarm can be triggered.
Tire pressure low,

Low tire pressure rear

274 Car carecompressor uses a lubricant that circu-
lates with the coolant.
Note
The A/C system cannot be switched on
when the outside temperature is below 32°F
(0°C). Turn on the A/ C system when the car
is standing in a warm place. Simplest is to
always have the A/C button pressed in. The
A/C system will then cu t in automatically
when the outside temperature is high
enough.
Headlight aimingThe vehicle has a visual optical headlight
aiming system equippe d with vertical
aiming device. The aim has been preset at
the factory and should normally not need
further adjustments.
If your headlights are damaged in a crash,
the headlight aim may be affected. If you
believe your headlights need to be
re-aimed, we recommend that you take it to
your Saab dealer for service. However, it is
possible for you to re-aim your headlights as
described in the following procedure. To check the aim, the vehicle should be
properly prepared as follows:
The vehicle shall be placed so that the
headlights are 25 ft (7.6 m) from a light
colored wall or other flat surface. The
aiming area should be darkened, this will
improve your ability to see the beam of the
low beam headlight being aimed.
An optical headlamp aimer can also be
used and will than replace the wall.
The vehicle must have all four wheels on a perfectly level surface which is level all
the way to the wall or other flat surface.
The vehicle should be placed so it is perpendicular to the wall or other flat
surface.
The vehicle should be unloaded and fuel tank full, and one person or 160 lbs.
(75 kg) on the drivers seat.
The vehicle should be fully assembled and all other work stopped while headlight
aiming is being done.
The vehicle should not have any snow, ice or mud attached to it.
Tires should be inflated to the prescribed pressure.
Close all doors.
Rock the vehicle to stabilize the suspen- sion.
Headlight aiming is done with the vehicle
low beam lamps. The high beam lamps will
WARNING
Before checking/adjusting the headlight
aiming, switch off the engine to avoid
danger of fingers and hands being injured
by moving parts.
The radiator fan can start up even when
the engine is switched off.NOTICETo make sure that your headlights are
aimed properly read all instructions
before beginning. Failure to follow these
instructions could cause damage to
headlight parts or a not correctly aimed
headlight.
