2006 SAAB 9-5 engine

132 Interior equipment and trunkTrunk pass-through hatch A trunk pass-through hatch is incorporated in the rear seat backrest
to enable long, narrow items to be carried inside the car.
Items should not weigh more than 33 lbs. (15 kg) nor be more than
2 yards (2 metres) in length. See the label on the hatch.
1 Fold down the armrest.
2 Raise the hatch by lifting the handle.
Before loading or unloading long items, switch off the engine and
apply the parkingbrake. This averts the danger of the car moving off
suddenly if a long item were to knock the gear or selector lever into
gear. Tie DownsThe tie downs for securing the load are fitted inside the trunk. Place
the load as far in as possible.
WARNING
 Anchor the load securely (e.g. using middle safety belt) to
avoid danger of injury resulting from displacement of load on
hard braking.
 Do not exceed the load capacity of the car, as this will alter its
handling characteristics (see page 260).

142 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.
The parking lights, hazard warning lights and interior lighting all work. OFF position Gear lever no longer locked.
Certain electrical circuits operationalON position All electrical circuits working. Do not leave the key in the ON position
when the engine is not running. Turn the key to OFF to switch off the
electrical circuits. In the ON position certain warning and indicator lights
come on as a check, and they normally are extinguished after about
3 seconds.ST (starter) position The starter operates when the key is turned to this position. When
released, the key will spring back to the ON position. If the engine fails to
start, the key must first be turned back to the position between OFF and
LOCK before the starter can be operated again.
When the starter motor is running, several electrical circuits are
disconnected to facilitate starting.

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
NOTICETake 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 crash9
– 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.

144 Starting and drivingIt 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 engineAvoid 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.
The engine has an automatic choke and
should be started as follows:
Cars with manual transmission
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. Wait
20–30 seconds before running the
starter again, to give the battery time to
recover.
Note:
On cars with manual transmission, if the
starter fails to engage when the ignition key
is turned to the start position, make sure the
clutch pedal is full depressed. Misposi-
tioned floor mats or other obstructions
under the clutch pedal may affect starting.
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. Wait
20–30 seconds before running the
starter again, to give the battery time to
recover.
Let the engine idle for about 10 seconds. Do
not open the throttle wide for at least
2–3 minutes after starting.  The tail pipe of the exhaust system
can become very hot during driving.
Bear this in mind when loading and
unloading the car.
 Do not rest or sleep in the car when
parked with the engine running. There
is a risk of depressing the accelerator
which could lead to engine damage.
There is also the risk that exhaust
gases may enter the cabin.

145 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.
NOTICEIf 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.

146 Starting and drivingImportant
considerations for
drivingThe engine-management system in the
Saab 9-5 is called Saab Trionic T7. The
system manages the ignition, fuel injection
and turbo boost pressure.
The Trionic T7 system developed by Saab
is an intelligent engine-management
system designed to achieve optimum driv-
ability under differing driving conditions.
The system makes adjustments automati-
cally, for instance, if the car is being driven
at altitude (oxygen-deficient air), for differ-
ent grades of fuel (AON 87–93) and for dif-
ferent load conditions.
1 Starting and driving
 Refrain from using full throttle before
the engine has warmed up (before
needle in mid-range on temperature
gauge).
 A safety function prevents the engine
from revving faster than 6,000 rpm by
limiting the induction air.
2 Stopping the engine
 Do not rev the engine immediately
before switching it off – stop the engine
when it is idling.
3 Regulating the boost pressure
 One of the advantages of boost pres-
sure regulation is that the engine can
also be run safely on gasoline with a
lower octane rating, although not lower than AON 87. However, engine perfor-
mance will fall slightly and heavy load-
ing and laboring should be avoided. For
optimum performance, use the recom-
mended grade of fuel.
 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.

NOTICE If the engine sounds strange there is a
fault in the system. Have the car
checked without delay by a workshop.
We recommend that you contact an
authorized Saab dealer.
 The use of fuel with too low an octane
rating can cause serious engine
damage.
WARNING
If the engine is being run with the car on a
rolling road or dynamometer, longer than
for a standard state emission inspection,
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 corresponding road speed.

147 Starting and driving
Important considerations with
catalytic 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).
To ensure that the catalytic converter con-
tinues to function properly, and also to avoid
damage to the converter and its associated
components, the following points must be
observed:
 Have the car serviced regularly in accor-
dance with the service program. The fuel
and ignition systems are particularly
important in this context.
 Always be alert to any misfiring of the
engine (not running on all cylinders) and
any loss of power or performance. At the
first sign of a malfunction, reduce speed
and take the car to a workshop as soon as
possible. We recommend that you con-
tact an authorized Saab dealer.  If the engine fails to start (in very cold
weather or if the battery is flat), the car can
be  started (manual gearbox only) or
started using 5

 to a donor
battery. However, as soon as you have
started the engine, it is important that it
runs on all cylinders. If it is misfiring, allow
it to idle for up to five minutes to give it time
to settle and run smoothly. If, after this
time, the engine still fails to run properly,
turn off the engine and get in touch with a
workshop for advice. We recommend that
you contact an authorized Saab dealer.  Never park the car on dry grass or other
combustible material. The catalytic con-
verter gets very hot and could therefore
start a fire.
 Never drive off if the engine is misfiring.
 If you jump start the car when the engine
is already up to normal temperature, the
engine must start to run on all cylinders.
Stop jump-starting if the engine fails to
start immediately.
Failure to follow these directions could
result in the catalytic converter and associ-
ated components being damaged, and
could represent a breach of the warranty
conditions.
NOTICEUse only unleaded gasoline. Leaded gas-
oline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.
NOTICEIf the car runs out of fuel, it is possible for
air to get into the fuel system. If this
happens, the catalytic converter may
overheat and be damaged.
