2008 SAAB 9-5 check engine

64 Instruments and controlsAutochecking of lights,
main instrument panel The above warning and indicator lights
should come on when the ignition is
switched on prior to starting. They should go
out after about 3 seconds.
The following lights light up until the engine
is started, presuming that no fault exists:
Oil pressure warning light .
Warning, charging .
InstrumentsTachometerThe tachometer indicates the engine speed
in thousands of revolutions per minute. The
needle may be allowed to enter the broken
red zone on the dial only for an instant.
A safety cut-out function (in the fuel system)
prevents the engine speed from exceeding
approximately 6,000 rpm.
Odometer and trip meter The odometer records the distance traveled
in miles on U.S. vehicles and on Canadian
vehicles the distance indicated is in kilome-
tres, and the trip meter in miles and tenths
(kilometres and tenths of kilometres on
Canadian vehicles). Reset button The reset button has two functions, deter-
mined by whether the ignition is ON or OFF.
When the ignition is ON, pressing the
button will reset the trip meter.
When the ignition is OFF, the display
lights up enabling you to read the odome-
ter and trip meter. Pressing the button a
second time will reset the trip meter.

Speedometer(U.S. speedometer shown)
The speedometer receives signals from the
wheel sensors in the ABS system.
Cars sold in U.S.: The speedometer dis-
plays the speed of the car in miles per hour
(mph).
Cars sold in Canada: The speedometer dis-
plays the speed of the car in kilometres per
hour (km/h).
Fuel gauge Fuel-tank capacity, 18.5 US gal. (70 liters).
The fuel gauge shows the amount of fuel left
in the tank. When this is down to about
2.5 gal. (10 liters), a warning light on the
main instrument panel will come on (see
page 61).
Use the Saab Information display (SID) to
check the approximate distance that can be
traveled on the remaining fuel
(see page 68).
Temperature gauge The temperature gauge shows the temper-
ature of the coolant. The needle should be
in the middle of the scale when the engine
is at normal operating temperature.
If the needle approaches the red zone,
which can occur in very hot weather or when
the engine is under a heavy load, drive in the
highest gear possible, keep the engine revs
low and avoid shifting down.

66 Instruments and controlsCheck fuse 1 (radiator fan) in the fuse panel
under the hood, see page 220.
If the needle repeatedly enters the red zone,
stop the car as soon as it is safe to do so and
check the coolant level by looking at the
level visible through the plastic tank – do not
remove the cap. If the coolant level falls below the MIN mark,
the Saab Information Display (SID) will
display the message
”Coolant level low.
Refill.”.

Pressure gaugeThe turbo gauge indicates the air volume for
combustion, which is equivalent to the
engine load.
Under certain barometric conditions, the
needle may enter the first part of the red
zone without necessarily indicating that a
fault has arisen.
If the needle repeatedly enters the red zone
and the engine at the same time loses
power because the monitoring system is
limiting boost pressure, you should contact
a workshop immediately. We recommend
that you contact an authorized Saab work-
shop.
NOTEIf the needle, despite the above action,
enters the red zone, stop the car immedi-
ately, let the engine idle.
If the needle stays in the red zone, stop
the engine.
WARNING
Never open the cap of the expansion tank
completely when the engine is hot, open
with care. The pressure in the cool-
ing-system can cause hot coolant and
steam to be released. Failure to heed this
warning may result in personal injury.

CHECK messages When the engine is started, CHECKING will
appear on the display for about 4 seconds
while the SID CHECK functions are being
performed.
When a CHECK message is activated while
driving, a chime sounds and the message
appears in SID. The number of possible
CHECK messages varies depending on the
car’s specifications.
If more than one CHECK message has
been generated, the
+ symbol will appear to
the left of the text on the display. The mes-
sages appear in order of priority.
If a new fault occurs whilst another message
is being displayed, the message relating to
the new one will appear for 10 seconds,
after which the display will return to the ear-
lier one.
Briefly press the CLR button to acknowl-
edge a message from the display. After
acknowledgement, the message is dis-
played each time the ignition is re-started
until remedied.The following messages may be displayed:
1) This message will be displayed approximately
600 miles (1,000 km) before the next scheduled
service is due, or when 365 days have elapsed
since the last service. The message should be
cleared at the time of that service (see the Saab
Warranties & Service Record Booklet).
This message can also be deleted by pressing
the CLR button for at least eight seconds until a
chime sounds. The message can only be deleted
when it is shown on the SID.

140 Starting and drivingIgnition switchThe combined ignition switch and
gear-lever lock is located in the center con-
sole between the front seats. The ignition
key can only be removed when reverse is
engaged (automatic transmission: selector
in ”P” position).
The key fits all the locks on the car. The key
number is specified on the small plastic
strap that comes with the keys when the car
is delivered. Keep a note of the key number
in a safe place, as you will need to quote it if
ordering a replacement key.
See also page 44.
LOCK position Engage reverse and turn the key to LOCK.
Automatic transmission: select ”P”.
The gear lever is locked. This is the only
position in which the key can be removed.

If the car does not startIf the text
”Key not accepted.
Contact service.”
is shown on the SID, after a failed start
attempt, the cause could be a fault in the
transmitter in the key, or in the receiver in
the ignition lock. The following should be
done:
Turn the key back to the LOCK position.
Turn the key to ON.
Press one of the buttons on the remote
control (the LED stops blinking).
Start the engine.
Try another key. If this works, then the fault
is in the first key.
We recommend that you contact an autho-
rized Saab dealer for checking and rectifica-
tion.
Note:
Certain electronic items, such as cellular
phones, may affect the starting produce-
dure. Be sure that all devices are clear of the
key/ignition switch area.
Starting the engine
NOTETake care not to spill drinks or to drop
crumbs over the ignition switch. If dirt or
liquid gets into it, the switch may not
operate properly.
WARNING
Always remove the key before leaving
the car.
Always apply the parking brake before
removing the ignition key.
WARNING
When starting the engine:
–Sit down in the driver’s seat.
–Depress the clutch pedal fully. If the
gear lever is not in the neutral position,
the clutch pedal must be fully
depressed or the car will jump for-
wards or backwards, which may
cause a crash.
–Never start the car from outside the
vehicle, e.g. through a wound down
window. This could lead to serious
personal injury.
Engage reverse (R) (position P for
automatic transmission) to remove the
ignition key. The key can only be
removed in this gear position.
Carbon monoxide (CO) is a colorless,
odorless, poisonous gas. Be alert to
the danger of CO – always open the
garage doors before starting the
engine in the garage.
There is also a danger of CO poison-
ing if the exhaust system is leaking.

143 Starting and driving
Useful tips on cold climate
startingIf the engine has failed to start after several
attempts in very cold weather, press and
hold the accelerator down to the floor and
run the starter for 5–10 seconds. This will
prevent the engine being flooded (exces-
sively rich fuel-air mixture).
Now start the engine in the normal way – do
not touch the accelerator.
If the engine stalls immediately after starting
(e.g. if the clutch was released too quickly),
do not touch the accelerator when restarting
the engine.
Limp-home modeThe engine management system has a
diagnostic feature that continually checks a
number of internal functions.
If, for example, a fault is detected in the
throttle valve, the engine management
system will go into Limp-home mode.This
limits:
idling control,
disables the cruise-control system and
limits the capacity of the A/C compressor.
If the limp-home mode is in operation
(”Engine malfunction (CHECK ENGINE)”
light on, see below) and the outside temper-
ature is close to or below freezing, you may
need to use some throttle on starting (some
pressure on the accelerator).
If the diagnostic system has detected a fault
in the engine-management system, the
”Engine malfunction (CHECK ENGINE)”
light on the main instrument panel will
come on (see page 58), indicating that you
should have the car checked as soon as
possible by a workshop. We recommend
that you contact an authorized Saab dealer.
NOTEIf the CHECK ENGINE warning light
starts to flash, ease off the accelerator
slightly. If the light does not cease to flash
within 5 seconds, stop the car in a suit-
able place as soon as possible and turn
off the engine. The car must be towed to
a workshop. We recommend that you
contact an authorized Saab dealer.
If the CHECK ENGINE warning light
flashes, it indicates that the engine is mis-
firing which can result in damage to the
catalytic converter.
