183 Starting and driving
Economical drivingFactors affecting fuel
consumptionThe fuel consumption of a car is greatly
affected by driving conditions, climate, road
conditions, speed, driving technique, 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)).Weather conditionsSummer temperatures give better fuel
economy than winter ones. The difference
can be as much as about 10%. Consump-
tion increases in cold weather because the
engine takes longer to reach its normal
operating temperature. The transmission
and wheel bearings also take longer to
warm up. Even distance affects consump-
tion: short journeys of 3–5 miles (5–8 km)
do not give the engine enough time to
reach its optimum temperature. Wind con-
ditions also have a marked effect on fuel
consumption.How to read the diagram:
If fuel consumption with the engine at
normal temperature is 28 mpg
(10 l/100 km), the actual fuel consumption
3 miles (5 km) after the engine has started
from cold will be:
– 23.5 mpg (12 l/100 km) at outside temp.
of 68 °F (+20 °C) (increase of 20 %).
– 17.7 mpg (16 l/100 km) at outside temp.
of 32 °F (0 °C) (increase of 60 %).
– 14 mpg (20 l/100 km) at outside temp. of
–4 °F (–20 °C) (increase of 100 %).
It is clear from the diagram that both dis-
tance driven and outside temperature have
a significant impact on fuel consumption,
after a cold start.
If the car is normally driven on short jour-
neys, 3–5 miles (5–8 km), for example to
and from work, the average consumption
will be 60–80% above the normal level.
Driving techniques To obtain the best running economy, with
regard to fuel consumption and general
wear, the car must be serviced regularly.
 High speed, unnecessary acceleration,
frequent braking and much changing
down all give higher fuel consumption.
 Frequent gear changing in traffic, starting
in cold weather, the use of studded tires
and roof racks, and towing a camper all
increase fuel consumption.
 Do not warm up the engine while the car
is stationary.
If idling, the engine will take much longer Percentage increase in fuel consumption
of engine starting from cold compared to
engine at normal temperature.

188 Starting and drivingTowing a trailer3Make sure you are familiar with the legal
requirements regarding speed limits for
towing, maximum trailer weights, trailer
braking requirements, and also any spe-
cial driving licence provisions.
Trailer hitch attachment3Trailer hitch attachments are available as
accessories. These are designed for a max-
imum trailer weight of 3500 lbs (1588 kg),
with trailer brakes.
The towbar must not be installed on certain
models. Contact an authorised Saab dealer
for information.
An electrical connection3 for the towbar
and an electrical unit are provided in the
electrical center on the left-hand side of the
luggage compartment.
If the car has a 13-pin Saab genuine electri-
cal socket then it is possible to supply a
trailer/caravan with rear fog lights and
reversing lights. The caravan can also have
interior and exterior lighting even when the
car’s ignition is switched off. In which case,
remember not to load the battery for too
long so that it is discharged and pre-
vents the car from starting.
There is also access to power in the caravan
during a journey, the caravan battery can be
charged for example.
Also, if the car has SPA, this is deactivated
automatically if a trailer is hitched up and
correctly connected to the Saab genuine
trailer socket.
Saab recommendations:
 Use a genuine Saab trailer hitch that is
designed and tested for your Saab.
WARNING
 Do not drive with a trailer on inclines
steeper than 15 %. The load on the
drive (front) wheels will be so low that
the wheels can start to spin and pre-
vent further progress.
 In addition, the car’s parking brake
may not always be sufficient to hold
the car and trailer securely, as the
wheels may start to slide.
 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.
 When you hitch up the trailer be sure
to attach its safety chains to the holes
by the hitch.93_US_MY09.book Page 188 Tuesday, April 15, 2008 10:30 AM

189 Starting and driving
 Contact your Saab dealer for advice on
which trailer hitch is designed for your car.
Recommendations for cars with
automatic transmissionThe following driving time limits are based
on the capacity of the cooling system in hot
weather, i.e. approximately 86°F (+30°C).
The following driving time limits are based
on the capacity of the cooling system in hot
weather, i.e. approximately 104°F (+40°C).When negotiating long hills, bear the follow-
ing important considerations in mind.
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 transmission increases:
 Gear change pattern is altered
 A/C compressor is switched off
 Max. engine torque is reduced.
The following message will be displayed on
the SID if the transmission fluid becomes
too hot:
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.
NOTICE Only use a towbar that has been
approved for your car. We recom-
mend that you entrust towbar installa-
tion to an authorized Saab dealer,
which can also provide important
information such as trailer weight.
Your authorized Saab dealer 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 contact a
Saab dealer for guidance on how to
connect a trailer hitch.
 Exercise care when driving on uneven
roads or against the curb if the car is
heavily laden. This particularly applies
to cars with 17" and 18" wheels.

190 Starting and drivingWhen continuing your journey, manually
select a low gear in which the engine speed
is about 3,500 rpm until the incline eases
(see page 168).
Recommendations for cars with
manual transmissionRises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
When the needle is just outside the red
zone, the A/C compressor will be switched
off and, on certain engine variants, the max-
imum engine torque will be limited.
When continuing your journey, select a low
gear in which the engine speed is about
3,500 rpm until the incline eases.
Trailer hitch loadThe weight distribution on the trailer makes
a lot of difference to the handling properties
of the car and trailer combination. With a
two-wheel trailer, concentrate the load over
the wheels and keep it as low as possible.
The trailer should be loaded so that the load
on the towball is 110–165 lbs. (50–75 kg).
Note that this load must be included in the
total load for the car. If this now exceeds the
specified load capacity, the load in the trunk
may have to be reduced by the correspond-
ing amount.
WARNING
Remember to use engine-braking (selec-
tor position M1, M2, or M3) to spare the
brakes when you are driving on a long or
steep downhill slope.
Overheating can cause the brakes to
fade!

191 Starting and driving
Checks before drivingMake sure that the car and trailer are in
good working order. This is essential since
towing a trailer increases the strain on the
car.
 Check and if necessary adjust the tire
pressure of the car and trailer.
 Make sure all wheel bolts are properly
tightened.
 Make sure that the equipment joining the
car and trailer is properly secured and
adjusted.
 Make sure the trailer’s electrical cable is
properly connected and is not so long that
it drags along the ground. Also, make sure
the cable is not too short and risks break-
ing when turning a corner.
 Check all bulbs.
 Check the car and trailer brakes.
 Make sure that all items on or in the
camper or trailer are properly secured.
 Make sure that the trailer’s jockey wheel is
raised and locked.
 Check the distribution of the load so that
the car and trailer are well balanced.
 Check that the rear view mirrors provide
the best possible rearward vision.
 Make sure the trailer’s safety cable is
correctly attached.
Driving considerationsAlways take extra care when towing a
trailer, as the car’s handling will be different
and its braking performance reduced. The
trailer’s braking system and suspension
also have a considerable effect on these
characteristics. See also "Driving with a
load" on page 192.
Drive carefully:
 Descending hills
 On uneven roads
 Over railway crossings
 When meeting large vehicles.
If the car has automatic transmission, select
gear M1 when ascending or descending
steep hills.
ReversingGet someone to help you keep an eye out
behind the trailer as the door mirrors do not
always provide sufficient rearward vision
when reversing.

193 Starting and driving
Driving with the trunk lid
openIf you must drive with the trunk lid open,
close all windows and the moonroof (if
equipped) and set the cabin fan to its high-
est speed setting.Driving in deep waterTowing the car
WARNING
Avoid driving with the trunk lid partly or
fully open, since exhaust fumes can be
drawn into the cabin.NOTICEDo not drive in puddles or water deeper
than 7 in. (20 cm) and do not drive faster
than 3–4 mph. Water can otherwise be
sucked into the engine. The engine will be
seriously damaged if water enters the
intake system.
WARNING
 Remember that the brake servo does
not operate when the engine is off.
Much greater pressure than normal
will therefore be required to operate
the brake pedal.
 Nor does the steering servo operate
when the engine is off. The steering
will therefore be much heavier than
usual.
 The towing vehicle should always be
heavier than the vehicle on tow.
 Never allow passengers to ride in the
car when it is on tow.
 Always seek professional help if the
car needs to be recovered.
 The ignition switch must be in the ON
position if the car is moved with the
engine not running.
 The steering wheel lock must be dis-
engaged before towing the car.
 The steering wheel lock disengages
when the remote control is inserted
into the ignition switch, if the battery
has sufficient charge.

194 Starting and drivingFront towing eyeThe front towing eye is stowed by the spare
wheel. On the left-hand side of the bumper
is a cover concealing the attachment point
(tapped hole) for the towing eye.1 Open the cover first at the lower edge
with a screwdriver for example. Watch
out for the paintwork.
2 Screw in the towing eye. The towing
eye has a left-hand thread!
3 Insert the wheel wrench into the eye to
tighten it properly.
To refit the cover: Start by inserting the top
edge of the cover. Then click in the lower
edge.
Rear towing eyeThe car has a permanent towing eye at the
rear under the bumper.
If the car is equipped with a towbar, this can
be used instead of the towing eye.
WARNING
 Make sure that the towing eye is
screwed in tightly. It has a left-hand
thread!
 The towing eye is only designed for
towing the car on roads. It must not
be used to pull the car out of a ditch,
for example.
 Make sure that all bystanders keep a
suitable distance, in case the towing
eye or tow rope should snap. The
towing eye or tow rope could catapult
off and cause seriously injury.
 Never drive with the towing eye fitted
to the front bumper. Return it to its des-
ignated storage space.

196 Starting and drivingWhatever the speed limit, the car must not
be towed at speeds exceeding 30 mph
(50 km/h) nor for a distance of more than
30 miles (50 km). If the car needs to be
transported over a longer distance, a tow
truck or flatbed truck must be called out.
The engine cannot be started by towing or
pushing the car. In an emergency, the
engine can be started as described under
"Jump starting" on page 197.
Vehicle recoveryIf the car has to be transported on a flatbed
truck, or similar, it must be securely
strapped down. There are attachment
points for this purpose on the underside of
the car. The attachment points are oblong
hole that have been reinforced to cope with
the stresses that arise during this type of
transport.
Transporting the carNOTICEIf a car with sports (lowered) chassis is
transported, for example on a flat bed
truck, take extra care not to damage the
spoiler and/or underbody.

216 Car careWipers and washersWiper bladesCheck and clean all wiper blades regularly.
If poor wiper performance is experienced,
clean the windshield with washer fluid. This
is particularly important if the car has been
through an automatic car wash, as these
sometimes leave a wax coating on the wind-
shield.
If wiper performance is still unsatisfactory,
fit new blades.
Windshield1 Press in the two catches (1) together.
2 Hold the wiper arm and move the wiper blade out and diagonally up.
Fitting the wiper blade 1 Align the wiper arm’s guide lug in the blade’s corresponding slot.
2 Move the blade in towards the wiper arm until the two catches grip the blade.
Check that the blade is fitted firmly.
Rear window, SportCombi1 Detach the blade from the arm by press-ing on the mounting for the blade from
below.
2 Fit the new blade by pressing the shaft of the blade into the arm's mounting.
The washer jet, which is located next to the
high-mounted brake light, is not adjustable.
