2005 SAAB 9-5 warning

197 Car care and technical information
Changing bulbsCheck that the new bulb is working when finished.Use only "Long Life" bulbs.Headlight aiming, see page 242.
Xenon headlight(if equipped)Xenon headlights produce roughly twice as much light as halogen
bulbs and have a significantly longer service life.
The lamp units consist of a gas discharge lamp containing xenon.
When the lights are switched on a very high voltage activates the
xenon gas. The lamps soon reach full intensity.
Cars with xenon headlights have automatic levelling. The levelling
system comprises two sensors on the front axle, one on the rear axle
and a control unit under the headlight housing. Headlight alignment
is regulated automatically to prevent dazzling oncoming traffic.
Alignment is also adjusted during braking.
WARNING
Before changing a bulb in the engine bay, 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.Xenon headlights are high voltage and must therefore be
changed at an authorized Saab workshop. Work involving
high-voltage components is potentially lethal.NOTICE Since the headlight lenses are made of plastic, rinse dried-on
dirt with water and allow it time to soften up before cleaning
the lenses. Avoid rubbing the lenses when dry and never use
solvents.
 Use de-icer spray instead of scraping the ice off.
NOTICE Do not fit bulbs with a higher rating than 55 W, since the head-
light reflector and the wiring of the car are not designed for a
higher wattage.
 Switch off the ignition before changing a bulb, to avoid possi-
ble short-circuiting.
 Do not touch the glass of the bulbs with your fingers. The oil
on your skin can shorten the life of the bulb.

Fuses
The fuses are housed in two fuse panels:
one at the end of the instrument panel on the
driver’s side, and one under the hood.
To check if a fuse has blown, first remove it
from the panel (see below). If the filament is
broken, the fuse has blown.
A special tool for removing fuses is provided
at the bottom of the fuse panel. Simply push
the tool onto the fuse, squeeze and remove
the fuse.
WARNING
To avoid the risk of short-circuiting and/or
fire breaking out in the electrical system,
the following advice should be heeded:
 Always consult an authorized Saab
dealer before modifying or adding any
electrical equipment. Failure to do so
can result in the electrical system
being damaged.
 Never replace a fuse with one having
a higher/lower rating than specified
(see page 213). The color of the fuse
indicates its amperage.
 If the same fuse blows repeatedly,
have the electrical system checked by
an authorized Saab dealer.
 If a MAXI fuse blows, it means that
there is a major fault in the electrical
system. Have the car checked by an
authorized Saab dealer.

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.

 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.

218 Car care and technical informationWhen to checkCheck your tires once a month or more.
Don’t forget your compact spare tire. It
should be at 60 psi (420 kPa).How to CheckUse a good quality pocket-type gauge to
check tire pressure. You can’t tell if your
tires are properly inflated simply by looking
at them. Radial tires may look properly infla-
ted even when they’re underinflated.
Be sure to put the valve caps back on the
valve stems. They help prevent leaks by
keeping out dirt and moisture.Tire Inspection and RotationAny time you notice unusual wear, rotate
your tires as soon as possible and check
wheel alignment. Also check for damaged
tires or wheels. See “When It Is Time for
New Tires” on page 219 and “Wheel Repla-
cement” on page 222 for more information.
The purpose of regular rotation is to achieve
more uniform wear for all tires on the
vehicle. The first rotation is the most impor-
tant.
When rotating your tires, always use the
correct rotation pattern. Left front tire to left
rear. Left rear tire to right front. Right front to
right rear. Right rear to left front.
Don’t include the compact spare tire in your
tire rotation.
After the tires have been rotated, adjust the
front and rear inflation pressures as shown
on the Tire-Loading Information label. Make certain that all wheel nuts are properly tigh-
tened. See page 233.
Flat spottingAll tires get hot, especially on long journeys
or when the car is driven hard. After the car
has been parked with hot tires and the tires
have cooled down, a flat spot can form in the
tire, where it is in contact with the ground.
The same can occur if the car has not been
moved for a long time.
Flat spots can cause vibration that can be
felt through the steering wheel, similar to
that experienced when the wheels need
balancing.
Flat spots of this type disappear once the
tires get hot again, usually after 10–15 miles
(20–25 km) of driving at cruising speed.
WARNING
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel
could come off and cause an accident.
When you change a wheel, remove any
rust or dirt from places where the wheel
attaches to the vehicle. In an emergency,
you can use a cloth or a paper towel to do
this; but be sure to use a scraper or wire
brush later, if you need to, to get all the
rust or dirt off. See “Changing a wheel” on
page 231.

220 Car care and technical informationThe wheels and tires have been carefully
matched to the characteristics of the car and
play a key role in its outstanding roadhol-
ding and handling.
Do not take it for granted that a wheel/tire
combination will work in the best possible
way, just because it can be fitted to the car.
To ensure that the speedometer is as accu-
rate as possible it should be reprogrammed
if wheels of a different dimension are fitted.
Contact a Saab dealer.
Because of 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.
Store wheels lying flat or hanging –
never

standing upright.
NOTICEAlways
consult your Saab dealer before
changing the wheels and tires on your
Saab.
Wide wheels and tires with sidewalls that
are too low can:
 be damaged in potholes etc.
 cause springs, shock absorbers and
wheel bearings and body mountings
can be overloaded.
 cause the wheels to come into contact
with chassis and body components.
 can affect the function of the Elec-
tronic Stability Program (ESP).
The speed and load limits for the tires
must not be exceeded; see page 225.
Wheels larger than 17” must not be fitted.
The maximum permissible offset is
49 mm.
WARNING
Mixing tires could cause you to lose
control while driving. If you mix tires of
different sizes or types (radial and bias-
belted tires), the vehicle may not handle
properly, and you could have a crash.
Using tires of different sizes may also
cause damage to your vehicle. Be sure to
use the same size and type tires on all
wheels. It’s all right to drive with your
compact spare temporarily, it was devel-
oped for use on your vehicle. See
“Compact spare tire” on page 230.
WARNING
If you use bias-ply tires on your vehicle,
the wheel rim flanges could develop
cracks after many miles of driving. A tire
and/or wheel could fail suddenly, causing
a crash. Use only radial-ply tires with the
wheels on your vehicle.

Uniform Tire Quality GradingQuality grades can be found where applica-
ble on the tire sidewall between tread shoul-
der and maximum section width. For
example:Treadwear 200 Traction AA
Temperature AThe following information relates to the
system developed by the United States
National Highway Traffic Safety Administra-
tion, which grades tires by treadwear, trac-
tion and temperature performance. (This
applies only to vehicles sold in the United
States.) The grades are molded on the side-
walls of most passenger car tires. The Uni-
form Tire Quality Grading system does not
apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires,
tires with nominal rim diameters of 10 to 12
inches (25 to 30 cm), or to some limited-pro-
duction tires.
While the tires available on General Motors
passenger cars and light trucks may vary
with respect to these grades, they must also
conform to federal safety requirements and
additional General Motors Tire Perfor-
mance Criteria (TPC) standards.
TreadwearThe 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 a half (1.5) times as well on the govern-
ment course as a tire graded 100. The rela-
tive 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 prac-
tices and differences in road characteristics
and climate.Traction – AA, A, B, CThe traction grades, from highest to lowest,
are AA, A, B, and C. Those grades repre-
sent the tire’s ability to stop on wet pave-
ment as measured under controlled condi-
tions on specified government test surfaces
of asphalt and concrete. A tire marked C
may have poor traction performance. War-
ning: The traction grade assigned to this tire
is based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
Temperature – A, B, CThe temperature grades are A (the highest),
B, and C, representing the tire’s resistance
to the generation of heat and its ability to dis-
sipate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature can
cause the material of the tire to degenerate
and reduce tire life, and excessive tempera-
ture can lead to sudden tire failure. The
grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A
represent higher levels of performance on
the laboratory test wheel than the minimum
required by law.
Warning: The temperature grade for this tire
is established for a tire that is properly infla-
ted and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause
heat buildup and possible tire failure.
