warning light SAAB 9-5 2007 Service Manual

174 Starting and driving2 Wait until the needle has dropped back
to indicate normal temperature (roughly
midway, in the white zone) before stop-
ping the engine. If the coolant needs top-
ping up, unscrew the cap on expansion
tank carefully.
Top up, as necessary, ideally with a
50/50 mixture of Saab-approved coolant
and water. If only water is available, use
that, but remember to have the coolant
mixture checked as soon as possible. 3 As soon as possible, have the cooling
system checked by a workshop. We rec-
ommend that you contact an authorized
Saab dealer.
Towing a trailer3Trailer hitch attachment3Trailer hitch attachments are available as
accessories. These are designed for a max-
imum trailer weight of 3500 lbs. (1588 kg),
see also page 259.
Use only the electrical trailer hitch socket
provided in the trailer hitch kit.3
Saab recommends:
Use a Saab original hitch kit attachment
which is designed and tested by Saab.
Consult your Saab dealer regarding the
appropriate hitch kit for your car.If the car has a 13-pin genuine Saab electri-
cal socket, the trailer/caravan can be equip-
ped with rear fog lamp and reversing lamps.
The caravan can also have interior and
exterior lighting when the car’s ignition is off.
Do not put a load on the battery for so
long that it becomes discharged and the
car cannot be started.
There is also access to power in the caravan
during a journey, the caravan battery can be
charged for example.

WARNING
Exercise care when opening the hood
if the engine is overheated. Never
remove the expansion tank cap com-
pletely when the engine is hot.
The cooling system is pressurized -
hot coolant and vapor can escape.
These can cause injury to your eyes
and burns. Open the cap slowly to
release the pressure before
removing it.
WARNING
When towing a trailer, do not attempt
to negotiate a hill having a gradient in
excess of 15 %. The weight distribu-
tion over the front wheels of the car will
be insufficient to prevent wheelspin,
making further progress impossible.
In addition, the parking brake may not
always be able to hold the car and
trailer securely, with the result that the
wheels can start to slide downhill.
Always apply the trailer’s parking-
brake when unhitching it. There is oth-
erwise a risk of personal injury or
damage to the bumper should the
trailer start to roll.
NOTICEOnly use a towbar that has been appro-
ved for your car. We recommend that you
entrust towbar installation to an authori-
zed Saab workshop, which can also pro-
vide important information such as trailer
weight. Your authorized Saab workshop
has information on how the towbar is to be
installed and whether other measures
must be undertaken that could affect the
cooling system or other equipment.
We recommend that you consult an
authorized Saab dealer for guidance on
how to connect the trailer hitch electrical
system.

178 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.

182 Starting and drivingTires
The tire pressure should match the current
load and speed of the car; for cars sold in
U.S. see page 231; for cars sold in Canada
see page 267.
The tire pressures given apply to cold tires,
that is tires that are the same temperature
as the outside air temperature.
The tire pressure increases as the tires
become warm (e.g. during highway driving)
with approximately 0.3 bar (4 psi). When
the temperature of the tires changes by 50°
(10°C), the tire pressure 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.
Underinflated tires wear more quickly than
slightly overinflated tires.
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 drive at substantially lower or
higher speeds than normal.
WARNING
Check the tire pressure at least once a
month and before long journeys. Under-
inflation can result in:
Punctures
Separation of the tire and tread
Damage to the sidewalls
Damage to the rims on poor roads
Poor handling characteristics
Premature tire wear
Increased fuel consumption.95_U S _M 07.book Page 182 Friday, June 9, 2006 8:58 AM

186 Starting and drivingJump startingIf your battery has run down, you may want
to use another vehicle and some jumper
cables to start your Saab. Follow the steps
below to do it safely.To jump start your vehicle:
1 Check the other vehicle. It must have a
12-volt battery with a negative ground
system.
2 Get the vehicles close enough so the
jumper cables can reach, but be sure the
vehicles are not touching each other. If a
poor connection on the negative jumper
cable should exist, it is possible for
damage to be caused to electrical sys-
tems/components of either vehicle
should inadvertent contact be made.
You would not be able to start your car
and bad grounding could damage elec-
trical systems.
3 Turn off the ignition on both vehicles.
Turn off all lights that are not needed,
and radios. This will avoid sparks and
help save both batteries and it could
save your radio.
WARNING
When working on the battery, highly
explosive gas can build up. A spark
could ignite this gas that collects
around the battery.
Therefore, always avoid sparks and
open flames in the vicinity of the bat-
tery.
The battery contains corrosive sulfuric
acid. Always wear a face mask or gog-
gles when working on the battery.
If battery acid gets into the eyes or
splashes onto skin or clothing, wash
the affected area liberally with water.
If acid gets into the eyes or a large
quantity makes contact with the skin,
seek medical help.
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash your hands after
handling.
NOTICEIgnoring these steps could result in costly
damage to your vehicle that would not be
covered by your warranty.
Trying to start your car by pushing or pull-
ing it could damage your vehicle, even if
you have a manual transmission. If you
have an automatic transmission, your
vehicle cannot be started by pushing or
pulling it.
NOTICEIf the other system is not a 12-volt system
with a negative ground, both vehicles can
be damaged.
WARNING
You could be injured if the vehicles roll.
Set the parking brake firmly on each vehi-
cle. Put an automatic transmission in P
(Park) or a manual transmission in
Neutral.

187 Starting and driving
4 Open the hood and locate the battery.
Find the positive (+) and negative (–) termi-
nals on the battery.5 Check that the jumper cables do not
have loose or missing insulation. If they
do, you could get a shock and also the
vehicles could be damaged.
Before you connect the cables, here are
some basic things you should know.
Positive (+) will go to positive (+) and
negative (–) will go to a major metal
engine part with a good ground. Do not
connect (+) to (–) or you will get a short
that could injure you or would damage
the battery and maybe other parts as
well.
6 Connect the red positive (+) cable to the
positive (+) terminal of the vehicle with
the discharged battery.
7 Do not let the other end touch metal.
Connect it to the positive (+) terminal of
the good battery. Use a remote positive
(+) terminal if the vehicle has one.
8 Now connect the black negative (–)
cable to the good battery’s negative
terminal.NOTICEIf you leave your radio on, it could be
badly damaged. The repairs would not be
covered by your warranty.
WARNING
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.
WARNING
Using a match or flame of any kind near a
battery can cause battery gas to explode.
You can suffer burns or be blinded. Use a
flashlight if you need more light.
Be sure the battery has enough water.
The battery installed in your new Saab
has filler caps. Be sure the right amount
of water is there. Add distilled or boiled
water if the level is too low. If you don’t,
explosive gas could be present.
Be sure the electrolyte in the battery is not
frozen. Discharged batteries will freeze.
When connecting jumper cables to a
frozen battery, gas from the chemical
reaction inside the battery can build up
under the ice and cause an explosion.
Battery fluid contains acid that can burn
you. Do not get it on you. If you acciden-
tally get it in your eyes or on your skin,
flush the area with water and get medical
help immediately.

199 Car care and technical information
Battery
The battery is provided with a cover to pro-
tect it from radiated heat. If the battery is
exposed to high temperatures, its life will be
shortened. To remove the cover, release
the two clips along its long sides.
The cover fits the standard battery installed
in the car. If a new battery is to be fitted,
make sure that its dimensions are the same
as the standard one.
The battery is maintenance free and should
be changed if the electrolyte level is too low.
The indicator on the top side of the battery
will be white if the battery needs replacing.
The fluid level and the charge level should
be checked regularly.
If frequent short journeys are made, the bat-
tery may need to be given a booster charge.
This can be done either using a battery
charger or by taking the car for a long run.
A car with a standard equipment specifica-
tion and a fully charged battery can be left
for up to 40 days and still have a sufficient
charge for starting. If extra equipment is fit-
ted, such as a car phone, the charge may
only be sufficient for about 15 days.
WARNING
Work on the battery may entail an
explosion hazard, since the battery
gives off hydrogen which forms an
explosive mixture with the oxygen in
the air.
For this reason, always avoid sparks
or open flames when working near the
battery.
The battery contains corrosive sulfuric
acid. Always wear a face mask or
goggles when working on the battery.
If battery acid gets into the eyes or
splashes the skin or clothing, wash the
affected area liberally with water.
If acid gets into the eyes or a large
quantity makes contact with the skin,
seek medical help.
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash your hands after
handling.
NOTICEA discharged battery can freeze and frac-
ture. Batteries should therefore always be
stored away from frost.

204 Car care and technical informationChanging bulbs
Check that the new bulb is working when fin-
ished.
Use only "Long Life" bulbs.
Headlight aiming, see page 247.
Xenon headlight3Xenon headlights produce roughly twice as
much light as halogen bulbs and have a sig-
nificantly 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 head-
light housing. Headlight alignment is regu-
lated 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 headlights3 are high voltage
and must therefore be changed at a
workshop. We recommend that you
contact an authorized Saab work-
shop. 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 headlight reflec-
tor and the wiring of the car are not
designed for a higher wattage.
Switch off the ignition before chang-
ing a bulb, to avoid possible short-cir-
cuiting.
Do not touch the glass of the bulbs
with your fingers. The oil on your skin
can shorten the life of the bulb.

217 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:
DICE controls (among other things):
Front lights and interior lighting
Instrument illumination
Intermittent wiper operation
Electric heating of rear window and door
mirrors
Cooling fansTWICE controls (among other things):
Central locking.
Car alarm (Anti-theft system)

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. We recommend that you contact
an authorized 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 a
workshop. We recommend that you con-
tact an authorized Saab dealer.
