193 Car care and technical information
Maxi 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 dam-
aged. 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 seat.The 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 mod-
ules 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.
NOTEIf 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.

198 Car care and technical informationWheels Alternative wheels and tiresIf you wish to fit other tires or wheels than
those supplied with the car, consult your
Saab dealer first as to the possibilities avail-
able.
Wheels/tires combinations that are not
approved by Saab can negatively affect the
car´s directional stability, steering and brak-
ing in both wet and dry conditions.
Do not assume that a wheel/tire combina-
tion will function properly just because it will
bolt on.The wheels and tires have been carefully
matched to the characteristics of the car and
play a key role in its outstanding roadhold-
ing and handling.
Tire pressureTires need to be inflated to suit the load car-
ried and the maximum speed the car will be
driven (see the recommended tire pres-
sures on the back cover). Note that all
values apply to cold tires. For tires with an
aspect ratio less than /60, increase the tire
pressure by 3 psi (20 kPa) for rough roads
with potholes to minimize the risk of rim
damage.Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
Soft tires will cause faster wear than
over-pressurized tires. They also increase
fuel consumption.
If a valve is leaking, simply unscrew it and fit
a new one.
Important! Remember to adjust the tire
pressures if you change the load in the car
or intend to cruise at a substantially higher
or lower speed than normal.
NOTEFor wide wheels and/or low-profile tires,
bear in mind the following:
 Tires and wheels can be damaged in
potholes etc.
 Springs and dampers can be over-
loaded.
 The wheels can come into contact with
chassis and body components.
 The speed and load limits for the tires
must not be exceeded; see page 199.
 Wheels larger than 17” must not be fit-
ted. The maximum permissible offset
is 49 mm.
NOTECheck the tire pressures at least once
per month.
Underinflation is the main cause of:
 Tires wearing out prematurely.
 Damage to the sidewalls.
 Damage to the wheels.

199 Car care and technical information
Rotating tiresBecause the car has front-wheel drive, the
front tires tend to wear faster than the rear
ones. New tires should always be fitted in
pairs, so that tires on the same axle have the
same amount of tread.
If swapping the complete set, e.g. winter
tires for summer tires, mark the tires
removed to ensure that they go back in the
same position (e.g. FL for front left, RL rear
left, etc.).
Store wheels lying flat or hanging – never
standing upright.
Tire markingsAn example of the meaning of the different
markings in a tire size is given below for a
tire size of:
205/65 R15 94 V
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 as to the correct size
tire for your car (if different from the original
size) and also supply Saab approved winter
tires.Tire quality grading (cars sold in
U.S.)New tires must be graded and labeled in
accordance with new Federal regulations.
Standard tests are conducted to measure
performance in the areas of traction and
temperature resistance. Refer to the tire
sidewall for the specific quality grades of the
tires provided on your new Saab. Compact
spare tires are exempt.
DOT QUALITY GRADES
 Treadwear
 Traction AA, A, B, C
 Temperature A, B, C
All passenger car tires must conform to Fed-
eral safety requirements in addition to these
grades.
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.
Always move left rear to left front and right
rear to right front, so that the direction of
rotation remains the same.

200 Car care and technical informationUniform Tire Quality Grading (US)Quality grades can be found where applica-
ble on the tire sidewall between tread shoul-
der and maximum section width. For exam-
ple:
Treadwear 200 Traction AA
Temperature ATreadwearThe treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions on
a specified government test course. For
example, a tire graded 150 would wear one
and one half (1 1/2) times as well on the gov-
ernment course as a tire graded 100. The
relative performance of tires depends upon
the actual conditions of their use, however,
and may depart significantly from the norm
due to variations in driving habits, service
practices and differences in road character-
istics and climate.
TractionThe traction grades, from highest to lowest,
are AA, A, B and C. These grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C may
have poor traction performance.
Wear indicatorsThe tires incorporate wear indicators in the
form of smooth, treadless strips across the
width, which become visible when only
1.6 mm of tread remains. As soon as the
indicators become visible, new tires should
be fitted without delay.
Make sure you are familiar with the legal
limit for minimum tread depth in your
country and also any regulations gov-
erning the use of winter tires.
WARNING
The traction grade assigned to a tire is
based on straight-ahead braking, traction
test and does not include acceleration,
cornering, hydroplaning or peak traction
characteristics.
