2000 SAAB 9-5 warning

131 Starting and driving
If the car does not startIf the text “KEY NOT ACCEPTED” 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.
Contact an authorized Saab dealer for
checking and rectification.
Starting the engine Do not run the starter motor for more than
25 seconds at a time. Wait 20-30 seconds
before running the starter again, to give the
battery time to recover.
Avoid racing the engine or putting a heavy
load on it before it has warmed up. Drive
away as soon as the oil warning light has
been extinguished to enable the engine to
attain its normal temperature as quickly as
possible.
It is possible for air to enter the lubricating
system in conjunction with an oil or oil-filter
change, or if the car has been stored for
some time. This air can cause the hydraulic
cam followers to emit a ticking noise, which
can persist for up to 15 minutes after start-
ing. Although this is quite normal and does
not indicate any malfunction, it is advisable
not to exceed 3,000 rpm before the noise
has disappeared.
The hydraulic cam lifters are completely
service free; the valve clearance is set up at the factory and will not need any subse-
quent adjustment.
Starting the engineThe engine has an automatic choke and
should be started as follows:
Cars with manual gearbox
To start the engine the clutch pedal must
be fully depressed.
1 Depress the clutch pedal fully but do not
touch the accelerator.
2 Start the engine. Let the ignition key
spring back as soon as the engine has
started and is running smoothly – at very
low temperatures, you may need to run
the starter for up to 25 seconds.
Let the engine idle for about 10 seconds. Do
not open the throttle wide for at least
2-3 minutes after starting.
Cars with automatic transmission
1 The selector lever must be in the P or N
position.
2 Keep your foot on the brake pedal.
3 Start the engine. Let the ignition key
spring back as soon as the engine has
started and is running smoothly – at very
low temperatures, you may need to run
the starter for up to 25 seconds.
Let the engine idle for about 10 seconds. Do
not open the throttle wide for at least
2–3 minutes after starting.
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
 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.

133 Starting and driving
advantages of the system is that it
enables the engine to be run safely on
lower-grade fuel, although not lower
than AON 87.
 The maximum boost pressure is
adjusted automatically to the knocking
or pinging tendency of the engine.
Occasional, short-lived knocking when
the engine is under a heavy load is per-
fectly normal; the extent will depend on
the grade of fuel in the tank.
 Isolated instances of knocking are
more likely to occur with low-octane
fuel. This controlled form of knocking,
followed by a reduction in the boost
pressure, is a sign that the wastegate is
functioning and is perfectly safe for the
engine.
Important considerations with cata-
lytic convertersThe catalytic converter is an emission-con-
trol device incorporated in the car’s exhaust
system. It consists of a metal canister with a
honeycomb insert, the cells of which have
walls coated in a catalytic layer (mixture of
precious metals).
NOTEIf constant knocking occurs every time a
load is put on the engine, this indicates a
malfunction in the system.
Have the car checked without delay by an
authorized Saab dealer.
WARNING
If the engine is being run with the car on a
rolling road or dynamometer, to ensure
adequate cooling, air must be blown into
the engine compartment and under the
car at a rate equivalent to the ram-air
effect that would be obtained at the corre-
sponding road speed.
NOTEUse only unleaded gasoline. Leaded gas-
oline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.

possible running problems) is to keep the
tank well filled.
Before the onset of freezing temperatures in
winter, it may be advisable to add gasoline
anti-freeze to the fuel a few times to dispel
any condensation in the system.
Opening the fuel filler flap in an emergency,
see page 126.
Recommended fuel:The engine in your Saab 9-5 is designed to
operate on unleaded gasoline that has an
octane rating of 87 or higher. Octane rating
is determined according to the formula:
where MON is the Motor Octane Number,
and RON is the Research Octane Number.
The average of these two values is the
octane rating of the gasoline as it appears
on the pump at a retail gas station. This
value is sometimes referred to as the
"Anti-Knock Index" (AKI) or the "Average
Octane Number" (AON).To avoid deposit formation on the fuel injec-
tors which can cause poor driveability, use
only quality gasolines that contain deter-
gents and corrosion inhibitors. Because
gasolines sold at retail gas stations vary in
their composition and quality, you should
switch to a different brand if you begin expe-
riencing driveability and/or hard starting
problems shortly after refueling your car. In
recent years, a variety of fuel additives and
alcohols or oxygenates have been blended
with gasoline. These types of gasolines may
be found in all parts of the United States and
Canada, but particularly in geographic
areas and cities that have high carbon mon-
oxide levels. Saab approves the use of such
"reformulated" gasolines in its products,
which help in reducing pollution from all
motor vehicles, provided that the following
blending percentages are met by such
fuels:
 Up to 10% ethanol by volume, with corro-
sion inhibitors.
 Up to 15% MTBE by volume (methyl ter-
tiary butyl ether).
 Up to 5% methanol by volume, with an
equal amount of a suitable co-solvent and
added corrosion inhibitors.
Other, less common, fuel additives used by
some gasoline dealers are also acceptable,
provided that the resultant gasoline is not
more than 2.7% oxygen by weight.
Some Canadian and U.S. gasolines contain
an octane enhancing additive called meth-
lycyclopentadienyl manganese tricarbonyl
WARNING
 Never use fuel for any purpose other
than as engine fuel.
 Fuel is highly flammable and can
cause severe burns. Never use an
open flame in the vicinity of gasoline
and do not smoke when refuelling.

136 Starting and driving(MMT). If such fuel is used, your emission
control system performance may deterio-
rate and the malfunction indicator lamp on
your instrument panel may turn on. If this
occurs, return to your authorized Saab
dealer for service.
However, these blended gasolines are reg-
ulated and should never exceed these rec-
ommended blend percentages and service
station operators should know if their gaso-
lines contain detergents and oxygenates,
and have been reformulated to reduce vehi-
cle emissions. Nevertheless, if you begin to
notice a problem with the way your car starts
or runs shortly after it has been refueled, try
a different brand of gasoline.
FuelUse the correct type of fuel. The fuel filler
cap is located in the right rear fender. Do not
lift the nozzle while filling is in progress. NOTEHigher concentrations of methanol than
listed above, or the use of methanol-
blended gasoline without suitable
co-solvents and corrosion inhibitors,
can damage your car’s fuel system,
leading to the need for repairs which are
not covered by Saab’s product warranty.
WARNING
Gasoline is highly flammable and can
cause severe burns. Never use an
exposed flame in the vicinity of gasoline.
Never smoke when filling the vehicle up
with gasoline.
NOTEThe engine control module (ECM) mon-
itoring the engine parameters also
stores fault codes.
Under certain circumstances, this may
cause constant illumination of the
“Engine malfunction” lamp , thus
indicating a fault that must be checked
by your Saab dealer.
NOTE: always observe the following two
measures:
 Make sure that the fuel filler cap is
screwed on correctly before the
engine is started. Screw on the fuel
filler cap until you hear 3 distinct
clicks.
 Avoid driving with the fuel low level
indicator illuminated. The symbol
illuminates when less than approxi-
mately 2 gallons (8 litres) of fuel
remains in the tank.

138 Starting and drivingAutomatic transmission
The electronic control module for the auto-
matic transmission receives information on
engine torque and road speed, and also
controls the hydraulic pressure in the trans-
mission to ensure that gear changing is as
smooth as possible.
The position of the selector lever is shown
by the symbols adjacent to the lever and
also by an indicator on the main instrument
panel.
The ignition key can only be removed when
the selector lever is in the P position. When the car is stationary, the engine must
be at idling speed when the selector lever is
moved. You must have your foot on the
brake pedal to move the lever out of park.
If the accelerator is depressed while the
lever is moved, this will result in abnormal
wear in the transmission.
WARNING
 Make it a habit to keep your foot on the
brake when selecting a drive position,
to prevent the car creeping forward (or
backward if reverse is selected).
 The car must be at a standstill before
P, R or N is selected. You have to have
your foot on the brake pedal to move
the lever out of P. If the car is still
moving when a drive position is subse-
quently selected, this could cause an
accident or damage the automatic
transmission.
 Never park the car with the selector
lever in a drive position, even if the
parking brake is on.
 Always select "P" position and apply
the parking brake when leaving the
vehicle unattended.
NOTEAfter selecting a drive position, pause to
allow the gear to engage before you
accelerate.

Overheated transmission fluid If the automatic-transmission fluid should
overheat, the following message will appear
on the SID:
”TRANSMISSION OVERHEATING”. If this
happens, stop the car and wait for the mes-
sage to be extinguished. Continue driving in
a locked gear that produces an engine
speed of 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, with the wrong gear selected,
resulting in abnormally frequent gear
changing. Try selecting position 1, 2 or 3.
High ambient temperatures can also
increase the temperature of the transmis-
sion fluid or the oil cooler may be faulty.
Contact an authorized Saab dealer (see
also page 152).
Towing Towing of cars with automatic transmission,
see page 158.
NOTEIf the control module has actuated the
Limp-home function for the automatic
transmission, the car will remain in 4th
gear when D is selected, making it very
sluggish. To overcome this, move the
selector lever to position 2.
WARNING
Remember to use engine-braking (selec-
tor position 1, 2, or 3) to spare the brakes
when you are driving on a long or steep
downhill slope. Select the same gear as
you would on the corresponding uphill
slope.
Brake failure can result from overheated
brakes!

Cruise controlThe system is operated by means of the
controls on the stalk switch:
 ON/OFF (switch on/off).
 RES/– (Resume preset speed).
 SET/+ (to set the desired speed).
 CANCEL (Cancel operation of system,
e.g. to reduce speed temporarily).
When the system is ON, the CRUISE indi-
cator light will appear on the main instru-
ment panel and will be extinguished when
the system is switched OFF. If CANCEL is
selected, CRUISE will flash once. To set the desired speed Move the switch to ON. Accelerate to the
desired speed (minimum speed: 25 mph
(40 km/h)) and press SET/+.
To increase the preset speed Accelerate to the desired speed and press
SET/+.
You can also increase the speed of the car
using the SET/+ button. Press it once to
increase the speed by 1 mph (1.6 km/h) or
hold it in and release when the desired
speed is reached. Temporary increase in speed Press the accelerator to override the preset
speed, e.g. for overtaking.
When you release the accelerator, the
system will revert to the preset speed. To cancel temporarily Move the control stalk to CANCEL
(spring-loaded position before OFF posi-
tion). This will disengage the system but the
preset speed will be retained in the system memory. (The memory is deleted when the
engine is switched off.)
To re-engage the system To revert to the preset speed, slide the
switch to RES/–. This will only operate when
the car’s speed is above 25 mph (40 km/h). To reduce the preset speedThe cruise-control system will always disen-
gage automatically the moment that either
the brake pedal or the clutch pedal is
depressed.
It is also possible to reduce the speed by
means of the RES/– button.
Sliding the button to RES/– once will reduce
the speed by 1 mph (1.6 km/h). Holding the
button in the RES/– position will effect a
gradual reduction in speed until the button
is released. Disengaging the system The system will be disengaged:
 When the brake or clutch pedal is
depressed.
 When the switch is moved to CANCEL.
 When the switch is moved to OFF.
 When the engine is switched off.
 When the selector lever is moved to posi-
tion N (cars with automatic transmission).
WARNING
 Do not use the Cruise-control system
on wet or icy roads, in dense traffic or
on winding roads.
 Set the control to OFF when you do
not want to use the system, to prevent
the system being activated inadvert-
ently.

146 Starting and drivingBrakingTo avoid the brakes becoming overheated,
(e.g. when negotiating long descents with a
drop of several hundred feet), select a low
gear to use the braking effect of the engine.
If the car has automatic transmission, move
the selector lever to position 1 or 2.
When driving fast, you can help to prolong
the life of the brakes by thinking ahead and
braking harder for short periods, rather than
braking more moderately over long
stretches. Brake pad wear indicatorsThe outboard brake pads on the front
wheels incorporate pad-wear indicators.
When the lining is down to 3 mm, the pad
will produce a screeching, squealing or
scraping noise when the brakes are applied.
New pads should be fitted without delay.
Brake pads should only be replaced by
an authorized Saab dealer. To ensure optimum brake performance,
it is recommended that you use only
Saab original brake pads.
ABS brakesABS (antilock braking system) modulates
the brake pressure to the respective
wheels. Wheel sensors detect if a wheel is
about to lock, and the control module
reduces the pressure to that wheel and then
increases it once more until the tendency is
detected again.
The brake system is equipped with an Elec-
tronic Brake-force Distribution device
(EBD), which distributes the brake pressure
between the front and rear wheels, in such
a way as to achieve optimum braking perfor-
mance irrespective of the car’s speed and
load.
The ABS system has a built-in diagnostic
function which will switch on the Anti-lock
brake warning light if a fault is detected in
the system (see page 48).
WARNING
 It is prudent to try your brakes from
time to time, especially when driving in
heavy rain, on roads with a lot of sur-
face water, or in snow or slush. In such
conditions, the brakes may take
longer than normal to take effect. To
rectify this, touch the brake pedal peri-
odically to dry the brakes out.
The same applies after the car has
been washed or when the weather is
very humid.
 The brakes are power assisted and it
should be kept in mind that the servo
unit only provides the power assis-
tance when the engine is running.
 The brake pressure required when the
engine is off,( e.g. when the car is on
tow) is roughly four times the normal
pedal force required. The pedal also
feels hard and unresponsive.
 We advise against using wheels with
open wheel covers in winter, as the
brake components are then more
exposed both to slush, road salt and
grit.
WARNING
 The additional safety afforded by the
ABS system is not designed to allow
drivers to drive faster but to make
normal driving safer.
 To stop as quickly as possible, without
loss of directional stability, whether
the road surface is dry, wet or slippery,
press the brake pedal down hard-
without letting up, declutching
simultaneously, and steer the car to
safety.
