193 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.

195 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 222.
 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, gasoline anti-
freeze 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 gaso-
line anti-freeze 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.
Convertible: Avoid operating the soft top
at temperatures below 23°F (–5°C).
 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 tires be fitted. However, winter tires
achieve this extra grip at the expense of
grip on bare road surfaces.
Winter tires, particularly studded tires, gen-
erally 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.

196 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 293.
We recommend that you contact a Saab
dealer regarding approved tire chains. See
also page 263.
WARNING
 Do not drive at speeds above 30 mph
(50 km/h) when tire chains are fitted.
 Tire chains can reduce directional
stability.
 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 293, for information on wheel
and tire dimensions approved for the
fitting of tire chains.

256 Car careIf the tire pressure continues to drop, the
SID will issue a warning alarm when the
pressure is an additional 0.2 bar below the
first warning level.
Reduce speed (avoid heavy braking and
violent steering wheel movements) and
stop the car as soon as it is safe to do so.
Change the wheel.Malfunction
The message shown above will be dis-
played on the SID if:
 a wheel without pressure sensor is fitted
(e.g. spare wheel)
 one, two or three pressure sensors are
broken or missing
 two or more detectors are missing or
broken
 the receiver malfunctions
 a fault arises in the system.
The message shown above is not displayed
if none of the wheels have sensors, such as
if winter wheels without sensors are fitted.
TiresYour new vehicle comes with high-quality
tires made by a leading tire manufacturer. If
you ever have questions about your tire
warranty and where to obtain service, see
your Saab Warranty and Service Record
Booklet for details. Low tire pressure.

Contact Saab dealer.
WARNING
Poor maintained and improperly used
tires are dangerous.
 Overloading your tires can cause
overheating as a result of too much
friction. You could have an blow-out
and a serious accident. See “Loading
Your Vehicle” on page 267.
 Underinflated tires pose the same
danger as overloaded tires. The
resulting accident could cause serious
injury. Check all tires frequently to
maintain the recommended pressure.
Tire pressure should be checked
when your tires are cold.
 Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact – such as when you hit a
pothole. Keep tires at the recom-
mended pressure.
 Worn, old tires can cause accidents. If
your tread is badly worn, or if your tires
have been damaged, replace them.

259 Car care
Flat spottingAll tires get hot, especially on long journeys
or when the car is driven hard. After the car
has been parked with hot tires and the tires
have cooled down, a flat spot can form in the
tire, where it is in contact with the ground.
The same can occur if the car has not been
moved for a long time.
Flat spots can cause vibration that can be
felt through the steering wheel, similar to
that experienced when the wheels need bal-
ancing.
Flat spots of this type disappear once the
tires get hot again, usually after 10–15 miles
(20–25 km) of driving at cruising speed. If
the outdoor temperature is low it takes a
longer distance.
When It Is Time for New TiresOne way to tell when it’s time for new tires is
to check the treadwear indicators, which will
appear when your tires have only 1/16 inch
(1.6 mm) or less of tread remaining.
You need a new tire if any of the following
statements are true:
 You can see the indicators at three or
more places around the tire.
 You can see cord or fabric showing
through the tire’s rubber.
 The tread or sidewall is cracked, cut or
snagged deep enough to show cord or
fabric.
 The tire has a bump, bulge or split.
 The tire has a puncture, cut or other
damage that can’t be repaired well
because of the size or location of the
damage.
Treadwear indicatorsThe tires incorporate wear indicators in the
form of smooth, treadless strips across the
width, which become visible when only
2/32" (1.6 mm) of tread remains. As soon as
the indicators become visible, new tires
should be fitted without delay.
Make sure you are familiar with the legal
limit for minimum tread depth in your
country and also any regulations gov-
erning the use of winter (snow) tires.Treadwear indicator

Uniform Tire Quality GradingQuality grades can be found where applica-
ble on the tire sidewall between tread shoul-
der and maximum section width. For exam-
ple:
Treadwear 200 Traction AA Temperature
A
The following information relates to the
system developed by the United States
National Highway Traffic Safety Administra-
tion, which grades tires by treadwear, trac-
tion and temperature performance. (This
applies only to vehicles sold in the United
States.) The grades are molded on the side-
walls of most passenger car tires. The Uni-
form Tire Quality Grading system does not
apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires,
tires with nominal rim diameters of 10 to 12
inches (25 to 30 cm), or to some limited-pro-
duction tires.
While the tires available on General Motors
passenger cars and light trucks may vary
with respect to these grades, they must also
conform to federal safety requirements and
additional General Motors Tire Perfor-
mance Criteria (TPC) standards.Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions on
a specified government test course. For
example, a tire graded 150 would wear one
and a half (1.5) times as well on the govern-
ment course as a tire graded 100. The rela-
tive performance of tires depends upon the
actual conditions of their use, however, and
may depart significantly from the norm due
to variations in driving habits, service prac-
tices and differences in road characteristics
and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades repre-
sent the tire’s ability to stop on wet pave-
ment as measured under controlled condi-
tions on specified government test surfaces
of asphalt and concrete. A tire marked C
may have poor traction performance. Warn-
ing: The traction grade assigned to this tire
is based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
WARNING
Mixing tires could cause you to lose
control while driving. If you mix tires of
different sizes or types (radial and bias-
belted tires), the vehicle may not handle
properly, and you could have a crash.
Using tires of different sizes may also
cause damage to your vehicle. Be sure to
use the same size and type tires on all
wheels. It’s all right to drive with your
compact spare temporarily, it was devel-
oped for use on your vehicle. See
“Compact spare” on page 270.
WARNING
If you use bias-ply tires on your vehicle,
the wheel rim flanges could develop
cracks after many miles of driving. A tire
and/or wheel could fail suddenly, causing
a crash. Use only radial-ply tires with the
wheels on your vehicle.93U S M 06.book Page 261 Friday, February 18, 2005 1:15 PM

Steps for Determining Correct
Load Limit1 Locate the statement “The
combined weight of occupants and
cargo should never exceed
XXX pounds” on your vehicle´s
placard.
2 Determine the combined weight of
the driver and passengers that will
be riding in your vehicle.
3 Substract the combined weight of
the driver and passengers from
XXX kilograms or XXX pounds.
4 The resulting figure equals the avail-
able amount of cargo and luggage
load capacity. For example, if the
“XXX” amount equals 1400 lbs. and
there will be five 150 lb. passengers
in your vehicle, the amount of avail-
able cargo and luggage load capac-
ity is 650 lbs. (1400–750 (5x150) =
650 lbs.).5 Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calcu-
lated in Step 4.
6 If your vehicle will be towing a trailer,
load from your trailer will be trans-
ferred to your vehicle. Consult this
manual to determine how this
reduces the available cargo and
luggage load capacity of your vehi-
cle.
Winter tiresWinter (snow) tires are recommended for
winter climates where the majority of your
driving will be done on snow and ice. Winter
tires should be fitted to all four wheels to
maintain a proper balance. Your Saab
dealer can advise you of to the correct size
tire for your car (if different from the original
size) and also supply Saab approved winter
tires pre-mounted on steel or alloy rims.
Winter tires normally use a different speed
rating compared to summer/all season tires.
Make sure not to exceed the stated speed
rating on the tires you use.
