2007 SAAB 9-3 fuel consumption

90 Instruments and controlsPress the CLR button to acknowledge a SID
message. If you acknowledge a message
but do nothing about it, the message will be
displayed again the next time you start the
car.
When the engine is switched off the warn-
ing/indicator lights still active are displayed,
this is to remind the driver. At this point the
warning/indicator lights previously acknowl-
edged with the CLR button are also dis-
played.
You can adjust the settings of several of the
car’s systems, such as the alarm3, rain
sensor3 and climate control system. These
are known as Settings se page 94.Odometer and trip meterThe odometer records the distance trav-
elled in miles on U.S. vehicles and on Cana-
dian vehicles the distance indicated is in
kilometres, and the trip meter in miles and
tenths (kilometres and tenths of kilometres
on Canadian vehicles).xx
Reset buttonThe reset button is positioned immediately
to the left of the speedometer.
Press once to resets the trip meter, the igni-
tion shall be in position ON.
Trip computer function of the SIDSID is available in two levels, SID1 and
SID2. which one xx that your car has
depends on the car´s equipment level.

164 Starting and drivingPark Brake Shift LockThe transmission has a security function
known as Park Brake Shift Lock. To move
the gear selector lever out of the P or N posi-
tion, the gear selector lever detent (catch)
must be pressed in at the same time as the
brake pedal is held depressed.
The detent button on the selector lever has
to be pressed in before the lever can be
moved between certain positions.
Temporary override of Park Brake Shift
Lock, see page 166.
Adaptive gear change patternsThe adaptive gear change pattern function
adapts gear changing to the prevailing driv-
ing conditions. The transmission control
module senses the engine load, vehicle
speed and temperature of the transmission.
A suitable gear change pattern is then
selected automatically to avoid unneces-
sary gear changes and undesired increases
in transmission temperature.
Certain variants use a special change pat-
tern for the first few minutes after a cold start
so that the catalytic converter reaches its
working temperature more quickly.
Thermal transmission protectionThe transmission has built-in protection
against overheating. If the temperature of
the transmission fluid exceeds 302°F
(150°C), engine torque will be limited to
147 ft.lbs. (200 Nm).
The following message is shown on the SID:
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.Lock-upThe transmission’s torque converter has a
lock-up function. This can lock the torque
converter, thus reducing the engine speed
and fuel consumption.Kick-downWhen the accelerator is pressed down fully,
a down change is made to optimize acceler-
ation, e.g. for overtaking.
Following this, the next higher gear will be
selected at the optimum engine speed,
unless you ease off the accelerator before
reaching this.Gearbox too hot. Make a
safe stop. Open hood.

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
to reach its optimum temperature, and Percentage increase in fuel consumption
of engine starting from cold compared to
engine at normal temperature.

184 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. We recommend
that you contact 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 heater3The 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.

203 Car care
engine is equipped with CVCP (Continuous
Variable Cam Phasing). This means that
the engine’s intake camshafts can be
adjusted to achieve optimum functionality.
The switches are hydraulic.Engine familiesSaab cars imported into the United States
and Canada meet all applicable emission
control standards. The engine family and
appropriate tune-up specifications are iden-
tified on a label in the engine bay.
These engine families meet applicable EPA
Federal Standards, California State Stan-
dards and Canadian Federal Standards and
are equipped with the following systems:
sequential multiport fuel injection system
three way catalytic converter
crankcase emissions control system
evaporative emission system.
Emission control
systemsThe systems for controlling emissions to the
atmosphere require regular checking and
adjustment at the intervals specified in the
service program.
In addition to meeting the exhaust emission
regulations and thereby helping to keep the
environment clean, a correctly tuned engine
will also give maximum fuel economy.
Saab Trionic engine
management system, 4-cyl
engineThe Saab Trionic engine management
system is a unique Saab development that
combines sequential multiport fuel injection,
electronic distributorless ignition and turbo-
charger boost pressure control into one sys-
tem.
The Trionic engine control module (ECM)
monitors many different engine parameters
such as:
Intake manifold pressure.
Intake air temperature.
Crankshaft position.
Engine coolant temperature.
Throttle position.
The oxygen content of the exhaust gases.
The ECM receives information regarding
engine knocking from a sophisticated feed-
back function in the ignition discharge unit.
By processing all of this information, the Tri-
onic system can control fuel injector open-
ing duration, ignition timing and turbo-
charger boost pressure to provide excellent
engine performance while maintaining low
emissions and fuel consumption.
WARNING
Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth
defects and reproductive harm. In addi-
tion, certain fluids contained in vehicles
and certain products of component wear
contain or emit chemicals known to the
State of California to cause cancer and
birth defects or other reproductive harm.
