2009 SAAB 9-3 manual transmission

168 Starting and driving
Certain variants also have steering wheel controls for manual gear
selection. On these models, it is possible to change gear manually
using the selector lever and the steering wheel controls. The steer-
ing wheel controls are only active when the selector lever is in the M
position.
Select a higher gear by pressing the right-hand button and a lower
gear by pressing the left-hand button. Sentronic, manual gear selection
Move the selector lever to the manual position (M)
(to the left position D) to select gear manually.
Select a higher gear by pressing the selector lever
forward or a lower gear by pulling it back. The
selector lever will return to a position adjacent to
the letter M after each gear change.
An example of when you may wish to make
manual gear changes is when overtaking, to
enable you to remain in a low gear for an extended
period of time.
If the road surface is slippery, you may wish to start
off in 2nd or 3rd to reduce the risk of wheel spin.
When descending steep hills you should select a
low gear to increase the braking effect of the
engine and thus spare the brakes.
Manual gear selections are displayed on the main instrument
panel. The letter M and the current gear are displayed.
When the selector lever is in the M position, as opposed to the D
position, the engine is much more responsive to changes in accel-
erator position. The accelerator has a different feel.
When changing down, the desired gear can be selected but the
transmission will not change down until the engine speed is low
enough to avoid overrevving.Steering wheel controls for manual gear

170 Starting and drivingTo reduce the preset speedYou can reduce speed in any of the follow-
ing ways:
 Brake to the desired speed. Jog the
control to SET/+ or SET/–.
 Jog the control to SET/– to reduce the
speed by 1 mph (1.6 km/h).
 Hold the control in the SET/– position until
the desired speed is reached.Temporary increase in speedAccelerate, without shifting down (manual
transmission), to exceed the set speed such
as for overtaking. When you release the
accelerator, the car will return to the set
speed.To disengage the system
temporarilySlide the switch to the left towards OFF, but
only as far as to disengage the cruise con-
trol. Allow the switch to spring back.
To re-engage the systemSlide the switch to RESUME. The car will
return to the previously set speed. Vehicle
speed must exceed 15 mph (25 km/h).To disengage the systemThe system will be disengaged:
 As soon as the brake or clutch pedal is
depressed (cars with manual transmis-
sion).
 When the switch is slid towards OFF. See
also heading "To disengage the system
temporarily".
 When the switch is slid to OFF.
 When the TCS/ESP
® system is operative.
 When position N is selected (cars with
automatic transmission).
BrakingIt is good practice to try your brakes period-
ically while driving. This is particularly
important when driving in heavy rain, on
roads with a lot of surface water, in snow or
in salty slush. In such conditions a slight
delay in the braking effect may be noticed.
To minimize this delay, dry the brakes by
applying them lightly now and again. This
should also be done after the car has been
washed, and in extremely damp weather.
To avoid the brakes becoming overheated,
such as when negotiating long descents
with a drop of several hundred yards (hun-
dred metres), select a low gear to utilize the
braking effect of the engine. If the car has
automatic transmission, select 1st or 2nd
gear.
You can help to prolong the life of the brakes
by thinking ahead and braking harder over
short periods, rather than braking more
moderately over long stretches.

173 Starting and driving
All-wheel drive (XWD)3Essentially, the system consists of a PTU
(Power Take off Unit), propeller shaft, RDM
(Rear Drive Module which contains an elec-
tronically controlled plate clutch, final drive
gear and differential) and driveshafts. This
system enhances driving characteristics
and stability. The system is always active
and cannot be deactivated. It works
together with the ESP system and the
engine and transmission control modules.
When driving at a constant speed, approx.
95% of the torque is distributed to the front
wheels and approx. 5% to the rear wheels.
The torque is distributed steplessly and
instantaneously between the front and rear
wheels, depending on the driving condi-
tions. If the car is fitted with eLSD (electron-
ically controlled plate clutch between the
rear wheels), the torque can also be distrib-
uted individually to the relevant rear wheel.For optimum system function, the car’s tires
should not have varying degrees of wear.
When the XWD system requires service,
the following message is shown on the SID:
When the service message is displayed,
the XWD system may have limited func-
tionality (or be completely disabled in
some cases, i.e. the car switches to
front-wheel drive). Contact a workshop
for information. We recommend that you
contact an authorised Saab dealer.
Traction Control
System (TCS)Anti-spin systemHow the system worksThe Traction Control System (TCS) is
designed to prevent wheelspin. This
enables the car to achieve the best possible
grip and, hence, maximum tractive effort,
together with greater stability.
The TCS system uses information from the
ABS system’s wheel speed sensors to
determine whether any wheel is spinning. If
any wheel is spinning, this is reduced on
all-wheel drive cars initially by changing the
torque distribution, secondly by reducing
the engine torque, and thirdly with the aid of
the wheel brakes. On front-wheel drive cars,
wheelspin is reduced initially by reducing
the engine torque, and secondly with the aid
of the wheel brakes. Service XWD.
WARNING
When driving normally, the TCS system
helps to improve the car’s stability, and
driveability under slippery road and
extreme driving conditions. The TCS
must not be regarded as a system to
enable the driver to maintain higher
speeds. The same precautions must be
adopted as normal for safe cornering and
driving on slippery roads.

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.

186 Starting and drivingRemember 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.
Driving with tire chains3Snow chains must only be fitted to the wheel
and tire dimensions that Saab recommends
in "Technical data" on page 283.
We recommend that you contact a Saab
dealer regarding approved tire chains. See
also page 247.
WARNING
 Do not drive at speeds above 30 mph
(50 km/h) when tire chains are fitted.
 Tire chains can reduce directional sta-
bility.
 Do not fit tire chains to the car’s rear
wheels.
NOTICE Check the links frequently for wear.
 Check that the chains do not foul the
wheel arch liner at full lock.
 Refer to the "Technical data" section
on page 283, for information on wheel
and tire dimensions approved for the
fitting of tire chains.

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.
