257 Car care
Winter tiresWinter (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.
Winter tires normally use a different speed
rating compared to summer/all season tires.
Make sure not to exceed the stated speed
rating on the tires you use.
Make sure that wheels with sensors for tire
pressure monitoring are fitted during
replacement if the car has automatic tire
pressure monitoring.Tire date codeTires should be regarded as perishable
goods. As the tires age, the rubber becomes
progressively harder, and the roadholding
ability of the tires diminishes. This is partic-
ularly true on winter tires.
Tires have a code that specifies their date of
manufacture. The first two digits denote the
week number and the last two digits the year
followed by a filled triangle.
Automatic tire pressure
monitoring systemThe system consists of a sensor in each
wheel and a receiver. The sensors are
located inside the tire in direct connection
with the air pressure valves.
Make sure that wheels with sensors for tire
pressure monitoring are fitted during
replacement if the car has automatic tire
pressure monitoring.Tire pressure information is transmitted
wirelessly to the receiver.
The system checks the tire pressures when
speed exceeds 19 mph (30 km/h).
The system is self-programming which
means that the wheels can be shifted
around without any need for adjustment.
The spare wheel has no sensor. The system
will trigger a warning/alarm because of that.
The sensor batteries last for 10 years or
around 160 000 km. The battery cannot be
replaced. The whole sensor must be
replaced.
WARNING
The system is an aid to the driver. The
driver always has the responsibility that
the tires have the correct air pressure.
For optimum safety, economy and com-
fort tire pressures should be checked reg-
ularly even if the automatic tire pressure
monitoring has not alarmed.
NOTETire replacement must take place with
great care to avoid damaging the sensors
that are built together with the valves.
Remove the rear side first.
Start to remove the tire opposite the
valve.
During removal the tire machine must
not come closer than ±10° from the
valve.
During fitting, start 20° after the valve
and finish 20° before the valve.
Do not inflate the tire with pressure
higher than 102 psi (700 kPa).

258 Car careThe system does not warn if the tire pres-
sure is too high.If the tire pressure decreasesIf the tire pressure decreases to 6 psi
(41 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 (159 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 tempera-
ture could also affect tire pressure.
If the system has triggered a low pressure
warning or alarm then the tire pressure must
be adjusted to the recommended pressure
in order to put out the warning or alarm.
For further information on tire air pres-
sure, see page 244.
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,
front right. Check tires.
Low tire pressure rear
left. Make a safe stop.

MalfunctionsThe above message is shown on the SID if:
a wheel without pressure sensor has
been fitted (e.g. spare wheel)
one or more pressure sensors are broken
or missing
a fault has arisen in the receiver
a system error has arisen.
Removing a tireRemove the tire with a tire machine. It is
important to follow the instructions for the
tire machine as well.
Do not fit the tire tool in an area ±10° from
the valve.
Start removing opposite the valve.
Remove the rear side first.
Fitting a tireFit the tire with a tire machine. It is important
to follow the instructions for the tire machine
as well.
Start to fit about 20° after the valve.
Finish fitting before an area 20° from the
valve.
Do not inflate the tire to a pressure higher
than 102 psi (700 kPa). Tire pressure system
failure. Contact service.

260 Car careCompact spareThe compact spare is light and easy to
handle when changing the tire. Its use is
only permitted when a standard tire has sus-
tained a puncture. The maximum life of the
tire is only just over 2,000 miles (3,500 km).
Do not exceed 50 mph (80 km/h) with the
compact spare fitted.
The tire pressure should be 60 psi
(420 kPa). Put the punctured tire in the
spare wheel well under the trunk floor.
Have the standard tire repaired and refitted
as soon as possible.The spare tire, the tools and the jack with its
crank are carried under a panel in the trunk.
Fold the carpeting forward to ease access to
the tools and spare tire.
The screwdriver handle has a “button” for
removing plastic rivets. This type of rivet
must be removed when changing the light
bulb in the trunk lid (see page 230).
Your Saab is equipped with a trip computer
and you can use its “Speed warning” func-
tion, to monitor driving speed since you
must not exceed 50 mph (80 km/h), see
page 92.
Driving with a compact wheel
fittedObserve the following when the compact
spare tire is fitted:
The compact spare is light and easy to
handle when changing a tire.
Do not drive further than necessary with
the compact spare fitted - the maximum
life of the tire is only just over 2,000 miles
(approx. 3,500 km).
Refit the standard tire as soon as possi-
ble.
Fitting a spare tire/wheel without pressure
sensor will trigger a malfunction
message, see page 259.
Important considerations when driving with
a compact spare tire:
The car’s ground clearance is reduced.
WARNING
The spare tire or punctured tire must be
stowed under the trunk floor, and secured
in place with the retaining nut.
WARNING
Do not exceed 50 mph (80 km/h). The
tire can overheat affecting the car’s
roadholding.
Tire pressure: refer to page 294.
The spare tire or punctured tire must
be stowed under the trunk floor, and
secured in place with the retaining nut.

268 Car care
The underside of the car also needs wash-
ing regularly, and this should be done extra
thoroughly at the end of winter. Clean the
underside of the car by hand if the car is
usually washed in an automatic car wash
without special facilities for underbody
cleaning.
Never wash or leave the car to dry in the
sun, but wipe it dry with a chamois leather
immediately after washing to avoid smears
and streaks.
Clean the inside of window glass using a
proprietary window cleaner. This is particu-
larly important when the car is new, as
upholstery and trim have a tendency to
sweat a little at first.
Keep the glass well polished, as this helps
to prevent misting.
Clean the outside of the windows with Saab
washer fluid. This is especially important if
the car has been washed in an automatic
car wash, as sometimes a wax treatment is
used that can contaminate the windshield
and impair the performance of the wipers.
In the U.S., Saab offers a full complement of
car care products. See your dealer or visit
us at www.saabcatalog.com.Convertible
If a pressure washer is used be heedful of
the following recommendations:
on the lower part of the car (not higher
than the door handles): max pressure
of 100 bar and not closer than 8 in.
(20 cm).
on the upper part of the car: tax pres-
sure of 100 bar and not closer than
32 in. (80 cm).
Do not use any drying chemicals or water-
proofing agents.
Avoid automatic car washes.
NOTEDo not use alcohol-based cleaners on the
plastic lenses of the front or rear lights, as
these can cause a crackling effect on the
lenses.
The door mirrors should be folded in
before the car enters an automatic car
wash.
SportCombi: To avoid the wiper arm to
break tape it down to the window when
using a drive-through carwash.
Try your brakes on leaving a car wash.
Wet brake discs reduce the performance
of the brakes.
Fixed antennae, such as for a mobile
phone, must be removed if the car goes
through an automatic car wash.
Cars with Saab Parking Assistance: Do
not spray the sensors or closer than 8 in.
(20 cm) to the sensors with a pressure
washer, as this can damage them.
WARNING
Read and follow the instructions on
the packaging of the recommended
cleaning agents and waterproofing
agents. We recommend that you con-
tact an authorized Saab dealer
regarding recommended cleaning
agents and waterproofing agents.
Never treat the soft top with hot wax or
similar.
