ignition SAAB 9-5 2007 Service Manual

154 Starting and drivingIf ”Automatic transmission3, fault indicator”
light appears on the main instrument panel,
the system has detected a fault in the auto-
matic transmission or its control module
(see page 62).
This also means that the Limp-home mode
has been selected, to guard against further
damage being done to the transmission. In
this mode, the automatic transmission
starts in 5th gear, and gear changes (if nec-
essary) will have to be made manually.
Stop the car in a safe place. Switch off then
restart the engine. If the fault is intermittent,
the transmission will operate as normal
despite the fault indicator being on. Have
the car checked at a workshop. We recom-
mend that you contact an authorized Saab
dealer.
It is not possible to select the SPORT or
Sentronic mode when the Limp-home mode
is active.
Gear changes must be made manually.
The following gears will be engaged in the
respective selector positions when the auto-
matic transmission is in Limp-home mode:
Overheated transmission fluid If the automatic-transmission fluid should
overheat, the following message will appear
on the SID:
”Gearbox too hot.
Make a safe stop.”
In this event, stop the car in a suitable place,
switch off the engine and open the hood.
Wait for several minutes then turn on the
ignition to check that the message has gone
out. When driving subsequent to the trans-
mission fluid overheating, select a gear in
which the engine speed is about 3,000 rpm.
Overheating of the automatic-transmission
fluid can occur when the car is towing a
heavy load, such as a camping trailer in hilly
country. High ambient temperatures can
also increase the temperature of the trans-
mission fluid or the oil cooler may be faulty.
Contact a workshop. We recommend that
you contact an authorized Saab dealer (see
also page 174).

gear when D is selected, making it very
sluggish.
Select position L to prevent unnecessary
wear on the transmission. The transmis-
sion then starts in 2nd gear. Once the car
is moving you can select position D.
When the indicator light is on, the car
must not be driven with a caravan or
trailer attached.

157 Starting and driving
Selector positions
P
To shift out of the P position you must
depress the brake pedal and the ignition
must be ON.
The parking position (P) must only be selected
when the car is at a complete standstill. The
selector lever is locked and the transmission is
mechanically immobilized. Always apply the
parking brake after parking the car.
The engine can be started. The key can be
removed.
R
The reverse (R) position must only be selected
when the car is at a complete standstill. The
detent-release button must be pressed before
the selector lever can be moved to R. Wait until
reverse gear has engaged (car starts to creep)
before touching the accelerator.
N
In the Neutral position (N), the transmission is
disengaged from the engine. The engine can be
started, but first ensure that the parking brake is
on, to prevent the car from moving off unexpect-
edly.
To prevent the engine and transmission from
becoming hotter than necessary, select N for
stops other than brief ones, e.g. if stuck in a traf-
fic jam.
The normal drive position (D) is recommended
for waiting at traffic lights.
D
The Drive position (D) is the position for normal
motoring. Gear changes between 1st and 5th
will take place automatically, the timing of which
is determined by the throttle (accelerator) posi-
tion and the speed of the car.
After moving the selector lever to D, pause to
give the gear time to engage (car starts to pull).
M
Move the selector lever from position D to M to
allow you to change gear manually. Refer to
page 156.
L
Select position L if you wish to drive in 1st gear.
No upchanges will be made if you pull off in posi-
tion L. If you move the selector lever from posi-
tion D or M to L at a high vehicle speed, the
transmission will automatically shift down
through 4th, 3rd and 2nd gears to 1st gear,
depending on the car’s speed. Use this position
for descending steep hills if the car is heavily
loaded to spare the brakes.

169 Starting and driving
When an object is approximately 3 feet
(90 cm) from the car, the sound pulses
change character markedly. A distance of
about 3 feet (90 cm) is suitable if you wish
to load or unload the luggage compartment.
If the distance between an object and the
corner sensors does not change for three
seconds, e.g. if you are reversing alongside
a wall, the system will switch to monitoring
straight back. The system indicates if the
distance to the wall decreases again.
The system can be disengaged for when
driving with a trailer. Press and hold the CLR
button on the steering wheel when the dis-
play shows "PARK ASSIST", until the dis-
play shows "PARK ASSIST OFF". The
system is re-engaged in the same way. The
system is also always activated when the
ignition key is turned to ON. Pressing a steering wheel button briefly will
not disengage the system, the display will
simply show the previously selected func-
tion.
Ice, snow and dirt can affect the sensitivity
of the sensors. In such cases a continuous
tone will sound warning the driver that the
system cannot measure the distance to an
object. You can turn the system off by press-
ing and holding the CLR button for
1.5 seconds.
If the text "PARK ASSIST FAILURE" is dis-
played on the SID, have the system
checked by a workshop. We recommend
that you contact an authorized Saab dealer.NOTICEReverse slowly so that you have time to
stop the car when the continuous tone is
heard at approx. 12 in. (30 cm).
NOTICETo function well, the sensors must be kept
clean. Ice snow and dirt can affect their
sensitivity.
Do not spray the sensors or closer than
8 in. (20 cm) to the sensors with a pres-
sure washer, as this could damage them.

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.

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.

193 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 ”Engine malfunction (CHECK
ENGINE)” lamp in the main instru-
ment illuminates, this indicates that the
Trionic ECM has detected a problem. The
car will continue to operate, but perfor-
mance may be diminished. You should
have your car checked by a Saab dealer
as soon as possible.

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.
