In case of emergency
Engine overheatingIf the engine overheats, safely pull off the
road and stop the vehicle in a safe place.
If steam is coming from the
engine compartmentTurn the engine off and get everyone
away from the vehicle until it cools down.
If no steam is coming from
the engine compartment1. Keep the engine running at idling
speed.
2. Open the hood to ventilate the engine
compartment.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn offthe engine and contact your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If the temperature gauge stays at the
overheated zone, turn off the engine.
4. After the engine has fully cooled down,
check the coolant level in the reserve
tank.
If the coolant level is below the “LOW”
mark, add coolant up to the “FULL” mark.
5. If there is no coolant in the reserve
tank, add coolant to the reserve tank.
Then remove the radiator cap and fill the
radiator with coolant.
If you remove the radiator cap from a hot
radiator, first wrap a thick cloth around the
radiator cap, then turn the cap counter-
clockwise slowly without pressing down
until it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it.
TowingIf towing is necessary, it is best done by
your Saab dealer or a commercial towing
service. Observe the following procedures
for safety.
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has fully cooled down.
When the engine is hot, the coolant
is under pressure. Removing the
cap while the engine is still hot
could release a spray of boiling hot
coolant, which could burn you very
seriously.
Never tow AWD vehicles (both AT
and MT) with the front wheels raised
off the ground while the rear wheels
are on the ground, or with the rear
wheels raised off the ground while
the front wheels are on the ground.
This will cause the vehicle to spin
away due to the operation or deteri-
oration of the center differential.

1. Check the transmission and differential
oil levels and add oil to bring it to the upper
level if necessary.
2. Release the parking brake and put the
transmission in neutral.
3. The ignition switch should be in the
“ACC” position while the vehicle is being
towed.
4. Take up slack in the towline slowly to
prevent damage to the vehicle.
Rear liftgate – if the rear lift-gate cannot be unlockedIn the event that you cannot unlock the
rear liftgate by operating the power door
locking switches or the remote keyless en-
try system, you can unlock it from inside
the cargo area.

1. Remove the access cover at the bot-
tom-center of the rear liftgate trim.
2. Locate the rear liftgate lock release le-
ver behind the rear liftgate trim panel.
Never turn the ignition switch to
the “LOCK” position while the ve-
hicle is being towed because the
steering wheel and the direction
of the wheels will be locked.

Remember that the brake booster
and power steering do not func-
tion when the engine is not run-
ning. Because the engine is
turned off, it will take greater ef-
fort to operate the brake pedal and
steering wheel.

If transmission failure occurs,
transport your vehicle on a flat-
bed truck.

Do not run the engine while being
towed using this method. Trans-
mission damage could result if
the vehicle is towed with the en-
gine running.

For vehicles with automatic trans-
mission, the traveling speed must
be limited to less than 20 mph (30
km/h) and the traveling distance
to less than 31 miles (50 km). For
greater speeds and distances,
transport your vehicle on a flat-
bed truck.

When you do checking or ser-
vicing in the engine compart-
ment while the engine is run-
ning
Engine hood
0
To open the hood:
1. If the wiper blades are lifted off the
windshield, return them to their original
positions.
2. Pull the hood release knob under the
instrument panel.
Wear adequate eye protection to
guard against getting oil or fluids
in your eyes. If something does
get in your eyes, thoroughly wash
them out with clean water.

Do not tamper with the wiring of
the SRS airbag system or seatbelt
pretensioner system, or attempt
to take its connectors apart, as
that may activate the system or it
can render it inoperative. The wir-
ing and connectors of these sys-
tems are yellow for easy identifi-
cation. NEVER use a circuit tester
for these wiring.
If your SRS airbag or seatbelt pre-
tensioner needs service, consult
your nearest Saab dealer.

Always stop the engine and set
the parking brake firmly to pre-
vent the vehicle from moving.

Always let the engine cool down.
Engine parts become very hot
when the engine is running and
remain hot for some time after the
engine is stopped.

Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire.

Always remove the key from the
ignition switch. When the ignition
switch is in the “ON” position, the
cooling fan may operate suddenly
even when the engine is stopped.
A running engine can be dangerous.
Keep your fingers, hands, clothing,
hair and tools away from the cooling
fan, belts and any other moving en-
gine parts. Removing rings, watch-
es and ties is advisable.

Maintenance and service
Engine oil
Checking the oil levelCheck the engine oil level at each fuel
stop.
1. Park the vehicle on a level surface and
stop the engine.
2. Pull out the dipstick, wipe it clean, and
insert it again.
3. Be sure the dipstick is correctly insert-
ed until it stops with the graphic symbol
“ ” on its top appearing as shown in
the illustration.
1) Notch
2) Upper level
3) Lower level4. Pull out the dipstick again and check
the oil level on it. If it is below the lower
level, add oil to bring the level up to the up-
per level.
If you check the oil level just after stopping
the engine, wait a few minutes for the oil to
drain back into the oil pan before checking
the level.
Just after driving or while the engine is
warm, the engine oil level reading may be
in a range between the upper level and
the notch mark. This is caused by thermal
expansion of the engine oil.
To prevent overfilling the engine oil, do not
add any additional oil above the upper lev-
el when the engine is cold.
Changing the oil and oil filterChange the oil and oil filter according to
the maintenance schedule in the “Saab
Warranty and Service Record Booklet”.
The engine oil and oil filter must be
changed more frequently than listed in the
maintenance schedule when driving on
dusty roads, when short trips are frequent-
ly made, or when driving in extremely cold
whether.
1. Warm up the engine by letting the en-
gine idle for approximately 10 minutes to
ease draining the engine oil.
2. Park the vehicle on a level surface and
stop the engine.
3. Remove the oil filler cap.
B00467

Use only engine oil with the rec-
ommended grade and viscosity.

Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If en-
gine oil gets on the exhaust pipe,
be sure to wipe it off.

Maintenance and service
Turbo models
Non-turbo models7. Remove the oil filter with an oil filter
wrench.8. Before installing a new genuine Saab
oil filter, apply a thin coat of engine oil to
the seal.
9. Clean the rubber seal seating area of
the bottom of engine and install the genu-
ine Saab oil filter by hand turning. Be care-
ful not to twist or damage the seal.
10.Tighten the oil filter by the amount indi-
cated in the following table after the seal
makes contact with the bottom of engine.
Please see your Saab dealer for correct
oil filter information for your vehicle.
11.Reinstall under cover.
12.Pour engine oil through the filler neck.
Oil capacity (guideline):
4.2 US qt (4.0 liters, 3.5 Imp qt)
The oil quantity indicated above is only
guideline.
The necessary quantity of oil depends on
the quantity of oil that has been drained.
The quantity of drained oil differs slightly
depending on the temperature of the oil
and the time the oil is left flowing out. After
refilling the engine with oil, therefore, you
must the dipstick to confirm that the level
is correct.
13.Start the engine and make sure that no
oil leaks appear around the filter’s rubber
seal and drain plug.
14.Run the engine until it reaches the nor-
mal operating temperature. Then stop the
engine and wait a few minutes to allow the
oil to drain back. Check the oil level again
and if necessary, add more engine oil.

Oil filter color Amount of rotation
Black 1 rotation
White 2/3 – 3/4 rotation

Never over tighten the oil filter be-
cause that can result in an oil leak.

Thoroughly wipe off any engine
oil that has spilled over the ex-
haust pipe and/or under-cover. If
left unremoved, the oil could
catch fire.
Be careful not to spill engine oil
when adding it. If oil touches the ex-
haust pipe, it may cause a bad smell,
smoke, and/or a fire.

Maintenance and service
eas with very high temperatures, or used
for heavy-duty applications such as tow-
ing a trailer, use of oil with the following
grade and viscosities is recommended.API classification SM (or SL):
SAE viscosity no.: 30, 40, 10W-50,
20W-40, 20W-50

Synthetic oilYou can use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using syn-
thetic oil, you must use oil of the same
classification, viscosity and grade shown
in this owner’s manual, and must follow
the oil and filter changing intervals shown
in the maintenance schedule.
Cooling system

Cooling fan, hose and con-
nectionsYour vehicle employs an electric cooling
fan which is thermostatically controlled to
operate when the engine coolant reaches
a specific temperature.
If the radiator cooling fan does not operate
even when the engine coolant tempera-
ture gauge exceeds the normal operating
range, the cooling fan circuit may be de-
fective. Check the fuse and replace it if
necessary. If the fuse is not blown, have
the cooling system checked by your Saab
dealer.
If frequent addition of coolant is neces-
sary, there may be a leak in the engine
cooling system. It is recommended that
the cooling system and connections be
checked for leaks, damage, or looseness. Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down com-
pletely. Since the coolant is under
pressure, you may suffer serious
burns from a spray of boiling hot
coolant when the cap is removed.

The cooling system has been
filled at the factory with a high
quality, corrosion-inhibiting, year-
around coolant which provides
protection against freezing down
to –33
F (–36
C). For adding, use
genuine Saab coolant or an equiv-
alent: a mixture of 50% soft water
and 50% ethylene-glycol basis
coolant. Use of improper coolants
may result in corrosion in the
cooling system. It is important to
maintain protection against freez-
ing and corrosion, even if freezing
temperatures are not expected.
Never mix different kinds of cool-
ant.
Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.

1. Check the coolant level on the outside
of the reservoir while the engine is cool.
2. If the level is close to or lower than the
“LOW” level mark, add coolant up to the
“FULL” level mark. If the reserve tank is
empty, remove the radiator cap and refill
as required.3. After refilling the reserve tank and the
radiator, reinstall the caps and check that
the rubber gaskets inside the radiator cap
are in the proper position.

Changing the coolant
Always add genuine cooling system con-
ditioner whenever the coolant is replaced.
Change the engine coolant and add gen-
uine cooling system conditioner using the
following procedures according to the
maintenance schedule.
1. Remove the under cover.
2. Place a proper container under the
drain plug and loosen the drain plug.
3. Loosen the radiator cap to drain the
coolant from the radiator. Then drain the
