169 Starting and driving
When an object is approximately 3 feet
(90 cm) from the car, the sound pulses
change character markedly. A distance of
about 3 feet (90 cm) is suitable if you wish
to load or unload the luggage compartment.
If the distance between an object and the
corner sensors does not change for three
seconds, e.g. if you are reversing alongside
a wall, the system will switch to monitoring
straight back. The system indicates if the
distance to the wall decreases again.
The system can be disengaged for when
driving with a trailer. Press and hold the CLR
button on the steering wheel when the dis-
play shows "PARK ASSIST", until the dis-
play shows "PARK ASSIST OFF". The
system is re-engaged in the same way. The
system is also always activated when the
ignition key is turned to ON. Pressing a steering wheel button briefly will
not disengage the system, the display will
simply show the previously selected func-
tion.
Ice, snow and dirt can affect the sensitivity
of the sensors. In such cases a continuous
tone will sound warning the driver that the
system cannot measure the distance to an
object. You can turn the system off by press-
ing and holding the CLR button for
1.5 seconds.
If the text "PARK ASSIST FAILURE" is dis-
played on the SID, have the system
checked by a workshop. We recommend
that you contact an authorized Saab dealer.NOTEReverse slowly so that you have time to
stop the car when the continuous tone is
heard at approx. 12 in. (30 cm).
NOTETo function well, the sensors must be kept
clean. Ice snow and dirt can affect their
sensitivity.
Do not spray the sensors or closer than
8 in. (20 cm) to the sensors with a pres-
sure washer, as this could damage them.

170 Starting and drivingEconomical motoringFactors affecting fuel
consumptionFuel consumption is greatly affected by the
general driving conditions, the way in which
the car is driven and at what speeds, the
weather, the state of the road, the condition
of the car, etc. Breaking-inFuel consumption may be somewhat higher
during the break-in period (the first 3,000–
4,000 miles (5,000–7,000 km) than stated.Weather conditionsFuel consumption can be as much as 10 %
lower in summer than in winter. The higher
consumption in cold weather is explained by
the longer time it takes for the engine to
reach normal operating temperature, and
for the transmission and wheel bearings to
warm up. Fuel economy is also affected by
the distance driven: short journeys of
3–5miles (5–8 km) do not give the engine
enough time to reach normal temperature.
Strong winds can also affect fuel con-
sumption. How to read the graph above:
If fuel consumption with the engine at
normal temperature is 28 mpg
(10l/100 km), the actual fuel consumption 3
miles (5 km) after the engine has started
from cold will be:
–23.5 mpg (12l/100 km) at outside temp. of
68°F (20°C) (increase of 20 %).
–17.7 mpg (16l/100 km) at outside temp. of
32°F (0°C) (increase of 60 %).
–14 mpg (20l/100 km)) at outside temp. of
–4°F (–20°C) (increase of 100 %).
As can be seen, both the distance travelled
by the car and the outside temperature have
a major impact on fuel consumption after
the engine has started from cold. Thus, if the
car is mainly used for short journeys of
3–5miles (5–8 km), the fuel consumption
will be 60–80 % higher than normal.

171 Starting and driving
Driving techniqueTo obtain the best running economy, not
only regarding fuel consumption but
general wear also, regular service is
required.
High speed, unnecessary acceleration,
heavy braking and much low gear work all
gives rise to higher fuel consumption.
Frequent gear changing in traffic, starting
in cold weather, the use of studded tires
and roof racks, and towing a trailer all
increase fuel consumption.
Do not run the engine when the car is
stationary.
If idling, it will take much longer before the
engine becomes hot. Engine wear is
greatest during this warming-up phase.
Therefore drive away as soon as possible
after the engine is started and avoid high
revving.Driving in a low gear results in higher fuel
consumption than in a high gear because
of the higher engine speed for a given
road speed. Always change up to a higher
gear as soon as traffic conditions allow
and use the highest gear as much as
possible.
Check the air pressure in the tires once a
month. Incorrect pressures increase tire
wear. It is better to have slightly higher
pressure than lower.
Check fuel consumption regularly.
Increased consumption can indicate that
something is wrong and that the car
needs to be checked by a workshop. We
recommend that you contact an autho-
rized Saab dealer.
Practical trials on the roads have demon-
strated that substantial savings in fuel con-
sumption can be made if the above advice
is heeded.
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).
WARNING
Never switch the engine off while driving
as the effect of the brakes and power
steering will be greatly reduced.

172 Starting and drivingEngine block heater3
33 3The following are just some of the benefits
to the car and the environment of using an
engine block heater:
Lower fuel consumption.
Exhaust emissions substantially reduced
over short runs.
Reduced wear on the engine.
Inside of car warms up faster.
The engine heater is effective at outside
temperatures up to 58–68°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,
electrical cabin heater that is not in use, this
should be stored in the luggage compart-
ment.
Driving in cold weatherBefore starting a journey in cold weather
you should check the following:
That the wiper blades have not become
frozen to the windshield/glass.
Brush any snow away from the air intake
for the heater system (opening between
hood and windshield).
It may be advisable to lubricate the
door-lock cylinder (use molybdenum
disulphide, MoS
2) to prevent its freezing.
If the lock has frozen, take care not to
break the key (or use the remote control)
– heat it first or spray it with de-icer.
Periodically during the winter, add gaso-
line anti-freeze to the fuel to dispel any
condensation in the fuel tank which could
freeze and cause problems in the system.
Keep the tank well filled to reduce the risk
of condensation forming.
If the car is parked outside in freezing
weather, fuel additives (gasoline
anti-freeze) will not do any good 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 gasoline anti-freeze when filling
up the tank. Condensation is caused by
changes in the outdoor temperature or by
the car being parked alternately in a
garage and outside. It is particularly important when the roads
are slippery that the brakes and tires be in
good condition.
Check the anti-freeze in the engine cool-
ant, see page 195.
The car´s trip computer will warn you when
there is a risk of slippery conditions. For fur-
ther information on this function, see
page 68.
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 (snow) tires, particularly studded
tires (where use is legally permitted), gener-
ally 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.

173 Starting and driving
If winter tires are fitted, the same type must
be fitted on all 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 them before they
reach the legal wear limit, as they gradually
lose their friction properties.
The best response if the car gets into a
front-wheel skid is to freewheel (manual
gearbox only), i.e. disengage the clutch (so
that the wheels are neither driven or
retarded by the engine.
If the car has automatic transmission, ease
up on the accelerator and steer carefully in
the desired direction.
In a rear-wheel skid, steer in the same direc-
tion that the rear of the car is moving.
Tire chains3
33 3If you want to fit tire chains (where legally
permitted) they should only be fitted to the
tires recommended under ”Specifications”
(see page 268).
Consult your Saab dealer for details of
approved tire chains.
Driving in hot weatherAlways check the coolant level before start-
ing a journey. When the engine is cold, the
coolant shall lie on or just above the
KALT/COLD mark on the expansion tank..
At the end of a journey, if the engine has
worked hard, allow it to idle for two or three
minutes before switching it off.
If the needle on the temperature gauge
enters the red zone:
1 Bring the car to a standstill but leave the
engine running. Do not remove the cap
on the expansion tank even if the tank is
empty. If the needle on the temperature
gauge continues to rise while the engine
is idling, switch off the engine.
WARNING
Do not exceed 30 mph (50 km/h)
when tire chains are fitted.
Tire chains can reduce the directional
stability of the car.
Tire chains must not be used on the
rear wheels. NOTECheck the links frequently for wear.
Check that the chains do not contact
the wheel-arch liner at full lock.
See section ”Specifications”,
page 268, for information on allowable
wheel dimensions for the fitting of tire
chains.

174 Starting and driving2 Wait until the needle has dropped back
to indicate normal temperature (roughly
midway, in the white zone) before stop-
ping the engine. If the coolant needs
topping up, unscrew the cap on expan-
sion tank carefully.
Top up, as necessary, ideally with a
50/50 mixture of Saab-approved coolant
and water. If only water is available, use
that, but remember to have the coolant
mixture checked as soon as possible. 3 As soon as possible, have the cooling
system checked by a workshop. We
recommend that you contact an autho-
rized Saab dealer.
Towing a trailer3
33 3Trailer hitch attachment3
33 3Trailer hitch attachments are available as
accessories. These are designed for a max-
imum trailer weight of 3500 lbs. (1588 kg),
see also page 261.
Use only the electrical trailer hitch socket
provided in the trailer hitch kit.3
Saab recommends:
Use a Saab original hitch kit attachment
which is designed and tested by Saab.Consult your Saab dealer regarding the
appropriate hitch kit for your car.
If the car has a 13-pin genuine Saab electri-
cal socket, the trailer/caravan can be
equipped with rear fog lamp and reversing
lamps.
The caravan can also have interior and
exterior lighting when the car’s ignition is off.
Do not put a load on the battery for so
long that it becomes discharged and the
car cannot be started.
There is also access to power in the caravan
during a journey, the caravan battery can be
charged for example.
WARNING
Exercise care when opening the hood
if the engine is overheated. Never
remove the expansion tank cap com-
pletely when the engine is hot.
The cooling system is pressurized -
hot coolant and vapor can escape.
These can cause injury to your eyes
and burns. Open the cap slowly to
release the pressure before
removing it.
WARNING
When towing a trailer, do not attempt
to negotiate a hill having a gradient in
excess of 15 %. The weight distribu-
tion over the front wheels of the car will
be insufficient to prevent wheelspin,
making further progress impossible.
In addition, the parking brake may not
always be able to hold the car and
trailer securely, with the result that the
wheels can start to slide downhill.
Always apply the trailer’s parking-
brake when unhitching it. There is oth-
erwise a risk of personal injury or
damage to the bumper should the
trailer start to roll.
NOTEOnly use a towbar that has been
approved for your car. We recommend
that you entrust towbar installation to an
authorized Saab workshop, which can
also provide important information such
as trailer weight. Your authorized Saab
workshop has information on how the
towbar is to be installed and whether
other measures must be undertaken that
could affect the cooling system or other
equipment.
We recommend that you consult an
authorized Saab dealer for guidance on
how to connect the trailer hitch electrical
system.

175 Starting and driving
Trailer weightMaximum recommended trailer weights for
different gradients, with a view to comfort
and drivability for manual and automatic
cars, are shown on the drawing.
Make sure you are familiar with the law
regarding speed limits for towing, maxi-
mum trailer weights, trailer-braking
requirements, and also any special
driving-license provisions
(see also page 261).
The specified trailer weights and gradients
assume that the journey starts at the hill and
therefore apply only to short periods. Recommendations for driving in hilly
terrain
The following time limits are based on the
capacity of the cooling system in warm
weather, i.e. approximately 86F (30C).
The following time limits are based on the
capacity of the cooling system in hot
weather, i.e. approximately 104F (40C).

176 Starting and drivingWhen negotiating long hills, bear the follow-
ing important considerations in mind:
Use Normal mode when driving with a
caravan or trailer on hilly roads. The adap-
tive gear change pattern function will
prevent the transmission overheating.
Rises in coolant temperature are indi-
cated by the temperature gauge in the
main instrument panel.Recommendations for cars with
automatic transmission
Rises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
The following steps are taken in order as the
temperature of the engine increases:
Gear change pattern is altered.
A/C compressor is switched off.
Engine torque is reduced.
The following message will be displayed on
the SID if the transmission fluid becomes
too hot:
“Gearbox too hot.
Make a safe stop.
If this message appears, stop the car as
soon as it is safe to do so and allow the
engine to idle until the message has gone
out. The selector lever should be in
position P.When continuing your journey, select
manual mode and a gear in which the
engine speed is about 3,000 rpm until the
incline eases (see page 157).
WARNING
Remember to use the braking effect of the
engine (position D or L) when you are
descending long or steep hills to spare
the brakes.
Brake failure can result from overheated
brakes!
