light SAAB 9-5 2009 Manual PDF

180 Starting and drivingTires
The tire pressure should match the current
load and speed of the car; for cars sold in
U.S. see page 229; for cars sold in Canada
see page 263.
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_US_MY09.book Page 180 Tuesday, April 15, 2008 11:03 AM

183 Starting and driving
Towing the car Gear lever in neutral (in cars with automatic
transmission: selector lever at N (neutral))
Turn on the parking lights.
Drive carefully and do not exceed the
speed limit for vehicles being towed.
Always try to keep the towrope taut by
gently applying the brake, as necessary.
This will avoid the towrope being jerked
violently.
The local regulations on towing speeds
must be followed.
The highest permissible towing speed is
30 mph (50 km/h), unless the legal limit is
lower. The longest permissible towing dis-
tance is 30 miles (50 km). If the car has to
be transported farther than that, summon a
tow truck. A flat bed tow truck is the pre-
ferred method to tow.
Failure to follow these guidelines can result
in damage.Cars with automatic transmission
The car cannot be push started. In an emer-
gency, it is possible to start the engine using
jump leads (see the section, ”Jump starting”
on page 184).
Transporting the car
NOTICENever use the towing eyes to pull the
car unstuck.
NOTICE The car must be towed front first.
 If the car is to be towed with the front
wheels off the ground, make sure the
parking brake is off, as this acts on the
rear wheels.
NOTICEIf a car with a sport (lowered) chassis is
transported, for example on a flat bed
truck, take extra care not to damage the
spoiler and/or underbody.
Never use the towing eyes to pull the car
unstuck

184 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
systems/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
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.

185 Starting and driving
help save both batteries and it could
save your radio.
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.

191 Car care and technical information
Saab Trionic engine
management systemThe Saab Trionic engine management
system is a unique Saab development that
combines sequential multiport fuel injection,
electronic distributorless ignition and turbo-
charger boost pressure control into one sys-
tem.
The Trionic engine control module (ECM)
monitors many different engine parameters
such as:
 Intake manifold pressure
 Intake air temperature
 Crankshaft position
 Engine coolant temperature
 Throttle position and
 The oxygen content of the exhaust gases.
The ECM receives information regarding
engine knocking from a sophisticated feed-
back function in the ignition discharge unit.
By processing all of this information, the Tri-
onic system can control fuel injector open-
ing duration, ignition timing and turbo-
charger boost pressure to provide excellent
engine performance while maintaining low
emissions and fuel consumption.
ORVR (Onboard Refueling Vapor
Recovery)Hydrocarbon vapors formed when refueling
will be recovered by the car and not
released into the atmosphere. The hydro-
carbons are absorbed in a evaporative
emission canister. When the engine is sub-
sequently started, the evaporative emission
canister is gradually purged as air is sucked
into it through a shut-off valve. The hydro-
carbon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked at least 3 times. Otherwise, it is pos-
sible for the CHECK ENGINE light to illumi-
nate.
Refueling, see page 146.
NOTICEThe Trionic engine management system
continuously monitors the operation of
these systems and has on-board diag-
nostic capabilities (OBD II).
If the ”Service Engine Light also known as
CHECK ENGINE” lamp in the main
instrument illuminates, this indicates that
the Trionic ECM has detected a problem.
The car will continue to operate, but per-
formance may be diminished. You should
have your car checked by a Saab dealer
as soon as possible.

200 Car care and technical informationWipers and washersCheck and clean all wiper blades regularly.
If poor wiper performance is experienced,
clean the windshield with a quality glass
cleaner. This is particularly important if the
car has been through an automatic car
wash, as these sometimes leave a wax
coating on the windshield.
If wiper performance is still unsatisfactory,
fit new blades.
Changing the windshield wiper
blades1 Hold the wiper arm and push the two
catches off the arm.
2 Move the blade along the extension of
the arm.
Fitting the wiper blade
1 Slide the new blade onto the arm until it
locks in position. Make sure that the end
of the wiper arm is within the blade
bracket.
2 Check that the blade is seated correctly.
Rear window, SportCombi1 Detach the blade from the arm by pres-
sing the blade’s mounting from underne-
ath.
2 Install a new blade by pressing the shaft
of the blade in the arm’s mounting.
The washer jet, which is located next to the
high-mounted brake light, is not adjustable.

202 Car care and technical informationChanging bulbs
Check that the new bulb is working when
finished.
Use only "Long Life" bulbs.
Headlight aiming, see page 248.
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, one on the front axle, one on
the rear axle and a control unit under each
of the two headlight housings. Headlight
alignment is regulated automatically to pre-
vent 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.
