Engine malfunction
(CHECK ENGINE)
WARNING
An illuminated “Engine malfunction
(CHECK ENGINE)” indicator light indi-
cates an engine-related problem. While
your car may be able to be driven with the
“Engine malfunction (CHECK ENGINE)”
indicator light illuminated (limp-home
mode), you are advised to have your car
serviced at an authorized Saab dealer as
soon as possible.
Continued driving without this problem
being corrected might cause serious
further damage to your car and create
unsafe driving conditions. The operator
should be prepared to take action if such
unsafe conditions arise (e.g. brake
smoothly, engage neutral, stop in a suita-
ble place, switch off the engine, etc.)
Engine malfunction.
Contact Saab dealer.
NOTICEThe car should be checked immediately
at a Saab dealer to prevent more serious
faults from arising.

56 Instruments and controlsThis light indicates when the front fog lights
are on (see page 74).
The front fog lights are switched off auto-
matically when the engine is switched off.
When the fog lights are next needed, they
will have to be switched on manually.
This light indicates when the rear fog light is
on (see page 74).
The rear fog light is switched off automati-
cally when the engine is switched off. When
the fog light is next needed, it will have to be
switched on manually again.This light should come on briefly when you
turn the ignition key to ON. If it doesn´t come
on, have it fixed so it will be ready to warn
you if there is a problem. This light indicates
when the brake fluid level is too low (see
page 180).
The following message is shown on the
Saab Information Display (SID):For safety reasons, stop the car and check
the level of the brake fluid (see page 180).
If the level is normal, depress the brake
pedal firmly two or three times. Now check
the level again. If the level is still normal, you
may drive the car, with considerable cau-
tion, to the nearest Saab dealer to have the
brake system checked.
The brake system provides Electronic
Brakeforce Distribution (EBD). This distrib-
utes the brake pressure between the front
and rear wheels, in such a way as to achieve
optimum braking performance irrespective
of the car’s load.
If a fault arises in the EBD function, the ,
and lights will come on. Also, the fol-
lowing message will appear on the Saab
Information Display (SID):
If this is the case, drive carefully and contact
a Saab dealer as soon as possible. Refer to
Brake warning light on page 56, Antilock
braking warning on page 54 and TCS OFF
or ESP OFF indicator (certain variants only)
on page 63.

58 Instruments and controlsThis light comes on when there is less than
about 2.5 gallons (10 litre) of fuel left in the
tank.
This light indicates that the headlights or
parking lights are on.This light comes on when the system is
engaged.
This symbol can be found in cars with
manual transmission. The symbol is not
activated until the engine is warm.
It is not always necessary or even recom-
mended to shift up to a higher gear when
this symbol lights up, such as when driving
in heavy traffic or down a steep hill.
Changing up a gear when the symbol
comes on does however improve fuel econ-
omy. Make it a habit to shift up when the
symbol lights up.
Autochecking of lights, main
instrument panelThe warning and indicator lights shown
above should come on when the ignition
switch is turned to ON. They should go out
after about 4 seconds once the engine has
started or after the fault-free self-diagnosis
of each system or function.

Courtesy Headlamp FeatureA delay function allows the low beam head-
lights and back-up lights to remain on for
about 30 seconds after the driver’s door has
been closed.
To activate this function:
1 After turning off the engine, remove the
remote control.
2 Open the driver’s door.
3 Pull the control stalk all the way towards
the steering wheel.
The low beam headlights and reversing
lights will come on and remain on for
30 seconds when the door is closed.
Instrument lightingThe brightness of the instrument lighting
can be adjusted by pressing the button (+ or
- signs on the button above the NIGHT
PANEL button).
Headlight levelling(cars with Bi-Xenon headlights)
Cars with Bi-Xenon headlights are
equipped with an automatic headlight level-
ling system, with self-calibrates each time
the vehicle is started. If a fault arises in the
automatic headlight levelling system, the
headlights will be angled down to avoid daz-
zling drivers in oncoming traffic. Adjust your
speed accordingly as the range of the head-
lights will be reduced. Check fuse 20 in the
engine bay fuse box (see page 203).
A fault in the system will produce the follow-
ing message on the Saab Information Dis-
play (SID):
Special equipment is required for adjusting
the basic headlight alignment.Headlight levelling

126 Starting and drivingLimp-homeThe engine management system has a
diagnostic feature that checks a number of
internal functions. If a fault is detected in the
throttle valve, the engine management
system will set the throttle system to the
limp-home mode. This means:
 idling control will be poor (uneven idling
since regulated by ignition and fuel
supply)
 engine performance will be reduced
 the cruise control will not function
 the capacity of the A/C compressor will be
limited.If the diagnosis function detects a fault in the
engine management system, the light
"Engine malfunction (CHECK ENGINE)" in
the instrument panel will come on (see page
55). Have the car checked at a Saab dealer
as soon as possible.
The following message is shown on the SID:
Important considarations 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 (precious
metal alloy).
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:
NOTICE If the engine sounds strange there is a
malfunction. Contact a Saab dealer
immediately.
 The use of fuel with too low an octane
rating can cause serious engine
damage.
Reduced engine power.
Contact Saab dealer.
NOTICEIf "Engine malfunction (CHECK
ENGINE)" warning light starts to flash
(indicating that the engine is misfiring and
the catalytic converter can be damaged),
ease off the accelerator slightly. The light
should go out or start to shine constantly.
If the light continues to flash despite
easing off the accelerator, you may
continue to drive the car but at the mini-
mum throttle permitted by the current traf-
fic situation. Have the car checked as
soon as possible at a Saab dealer.
NOTICEUse only unleaded gasoline. Leaded
gasoline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.

132 Starting and drivingIf your vehicle is certified to meet California
Emission Standards (indicated on the
underhood emission control label), it is
designed to operate on fuels that meet Cal-
ifornia specifications. If such fuels are not
available in states adopting California emis-
sions standards, your vehicle will operate
satisfactorily on fuels meeting federal spec-
ifications, but emission control system per-
formance may be affected. The malfunction
indicator lamp on your instrument panel
may turn on and/or your vehicle may fail a
smog-check test. See "Engine malfunction
(CHECK ENGINE)" on page 55. If this
occurs, return to your authorized Saab
dealer for diagnosis to determine the cause
of failure. In the event it is determined that
the cause of the condition is the type of fuels
used, repairs may not be covered by your
warranty.Some gasolines that are not reformulated
for low emissions may contain an octane-
enhancing additive called methylcyclopen-
tadienyl manganese tricarbonyl (MMT); ask
your service station operator whether or not
the fuel contains MMT. Saab does not
recommend the use of such gasolines. If
fuels containing MMT are used, spark plug
life may be reduced and your emission
control system performance may be
affected. The Engine malfunction (CHECK
ENGINE) light on your instrument panel
may turn on. If this occurs, return to your
authorized Saab dealer for service.
Engine Break-in PeriodPistons, cylinder bores and bearings need
time to obtain uniform, wear-resistant
surfaces.
If a new engine is driven too hard, this grad-
ual process of bedding-in will not be possi-
ble and the life of the engine will be short-
ened.
During the first 1,200 miles (2,000 km),
do not exceed 5,000 rpm.
In addition, refrain from driving the car at full
throttle, other than for brief instances,
during the first 1,800 miles (3,000 km).Wearing in new brake padsNew brake pads take time to bed in, about
90 miles (150 km) if the car is driven largely
under stop-and-go conditions or about
300 miles (500 km) of highway driving.
To extend the useful life of the pads, avoid
hard braking as much as possible.

154 Starting and drivingengine wear is at its greatest during this
period. Drive off as soon as possible after
starting the engine and avoid high engine
speeds.
 Drive as smoothly and thoughtfully as
possible. Match your driving to the
prevailing traffic conditions.
 Driving in a low gear gives rise to higher
fuel consumption than driving in a high
gear because of the higher engine speed
for any given road speed. Always shift up
as soon as traffic conditions allow and
drive in the highest gear as much as
possible.
 Check the tire pressure once a month.
Incorrect tire pressure increases tire
wear. It is preferable for the tire pressure
to be slightly high than too low. Under-
pressure increases fuel consumption. Check the fuel consumption regularly.
Increased fuel consumption can indicate
that something is wrong and that the car
needs to be checked at a Saab dealer.
Practical road tests have demonstrated that
substantial savings in fuel consumption can
be made if the above advice is followed.
Road conditionsWet roads increase fuel consumption, as do
unpaved roads and driving in hilly country
(the amount of fuel saved driving downhill is
less than the additional amount required to
climb the hill).
Engine block heater (standard
equipment in Canada, accessory in
U.S.)The following are just some of the benefits
to the car and the environment of using an
engine block heater:
 Lower fuel consumption.
 Reduced wear on the engine.
 Inside of car warms up faster.
 Exhaust emissions substantially reduced
over short runs.
The engine heater is effective at outside
temperatures up to 60–70°F (+15–+20°C).
The warmer it is outside, the shorter the time
the engine heater needs to be connected.
Longer than 1.5 hours is unnecessary.
If the car is equipped with a removable,
electric cabin heater that is not in use, store
this in the trunk.
WARNING
Never switch off the engine while driving
as the effect of the brakes and power
steering will be greatly reduced.

155 Starting and driving
Driving in cold weatherIn cold weather, special attention should be
paid to the following:
 Before driving off, make sure that the
wiper blades have not frozen to the wind-
shield.
 Remove any snow from the heating
system air intakes between the hood and
the windshield.
 If necessary, inject oil into the locks to
prevent them from freezing. Use molyb-
denum-sulphide oil (MoS
2). If the locks
freeze, exercise care when unlocking the
car (manual unlocking) to avoid breaking
the key. Warm up the key or use a de-icer.
 It is particularly important when the roads
are slippery that the brakes and tires are
in good condition.
 For how to check the level of antifreeze in
the engine coolant, see page 179. Add gasoline anti-freeze when refueling
several times before the onset of winter.
This will prevent condensation water in
the fuel tank from freezing and causing
interruptions in the fuel supply. The likeli-
hood of condensation is lowest when the
fuel tank is full.
If the car is parked outside and the
temperature is below zero, carburettor
spirit is of little use as it cannot remove
water that has already frozen. Park the
car in a warm place so that any ice that
may have built up melts, then add carbu-
rettor spirit when refueling.
Condensation is caused by temperature
fluctuations, either in the outside temper-
ature alone or when the car is alternately
parked outdoors and in a garage.
The car is equipped with tires designed to
provide optimum grip on both wet and dry
roads, although this has been achieved at
the expense of somewhat reduced grip on
snow and ice. For regular driving on snow
and ice, we therefore recommend that
winter (snow) tires be fitted.Winter tires, particularly studded tires,
generally make driving safer on snow and
ice.
Acquaint yourself with the legal provi-
sions governing the use of different
types of winter tires and snow chains.
Studded tires are not allowed in some
countries. If winter tires are fitted, the same
type must be fitted to all four wheels. Your
Saab dealer will be pleased to advise you on
the best tires for your car.
Remember that tires age: it may therefore
be necessary to change winter tires before
they reach the legal wear limit, as they grad-
ually lose their friction properties with age.
If you get into a front wheel skid and the car
has a manual transmission, the best
response is to freewheel, which means
declutching so that the wheels neither drive
nor brake, and to cautiously steer in the
desired direction.
If the car has automatic transmission, ease
off the accelerator slightly and steer cau-
tiously in the desired direction.
If you get into a rear wheel skid, steer in the
same direction as the movement of the rear
of the car.

163 Starting and driving
Driving with the trunk lid
openAvoid driving with the trunk lid partly or fully
open, since exhaust fumes can be drawn
into the cabin.
If you must drive with the trunk lid open,
close all windows and the sunroof (if fitted)
and set the cabin fan to its highest speed
setting.
Driving in deep water Driving at night
Bear in mind the following points, especially
when driving at night:
 Nighttime driving requires your full
concentration
 Do not rush. Count on your journey taking
slightly longer.
 The number of drivers under the influence
of drugs is likely to be greater at night than
during the day.
 Do not stare at the headlights of oncom-
ing vehicles.
 Avoid driving at night if you have poor
eyesight. Night vision deteriorates with
age.
 Keep your car’s headlights, windows and
mirrors clean. Also, if you wear glasses,
make sure they are clean.
 Make sure you are well rested before
starting a long journey. Take a break
every other hour.
 Only eat light meals. Heavy meals have a
tendency to induce tiredness.
 Wild animals prefer to move at dusk and
dawn.
 Check the headlight levelling setting (see
page 73).
NOTICEDo not drive in puddles or water deeper
than 7 in. (20 cm) and do not drive faster
than at idling speed. Water can otherwise
be sucked into the engine. The engine will
be damaged if water enters the intake
system.

169 Starting and driving
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.
4 Open the hood and locate the battery.
Find the positive (+) and negative (–) termi-
nals on the battery.
5 Check that the jumper cables do not
have loose or missing insulation. If they
do, you could get a shock and also the
vehicles could be damaged.
Before you connect the cables, here are
some basic things you should know.
Positive (+) will go to positive (+) and
negative (–) will go to negative (–). Do
not connect (+) to (–) or you will get a
short that could injure you or would
damage the battery and maybe other
parts as well.
6 Connect the red positive (+) cable to the
positive (+) terminal of the vehicle with
the discharged battery.7 Do not let the other end touch metal.
Connect it to the positive (+) terminal of
the good battery. Use a remote positive
(+) terminal if the vehicle has one.
8 Now connect the negative (–) cable to
the good battery’s negative terminal.
9 Attach the cable to the discharged
battery’s negative terminal.
10 Start the vehicle with the good battery
and run the engine for a while.
11 Try to start the vehicle with the
discharged battery. If it does not start
after a few tries, it probably needs
service.
12 Remove the cables in reverse order to
prevent electrical shorting. Take care
that they do not touch each other or any
other metal.NOTICEIf you leave your radio on, it could be
badly damaged. The repairs would not be
covered by your warranty.
WARNING
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.
WARNING
Using a match or flame of any kind near a
battery can cause battery gas to explode.
You can suffer burns or be blinded. Use a
flashlight if you need more light.
Be sure the electrolyte in the battery is not
frozen. Discharged batteries will freeze.
When connecting jumper cables to a
frozen battery, gas from the chemical
reaction inside the battery can build up
under the ice and cause an explosion.
Battery fluid contains acid that can burn
you. Do not get it on you. If you acciden-
tally get it in your eyes or on your skin,
flush the area with water and get medical
help immediately.
