175 Starting and driving
Use Normal mode when driving with a trailer
or trailer on hilly roads. The adaptive gear
change pattern function will prevent the
transmission from overheating.
Rises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
The following can also occur:
 the A/C-compressor can be shut off
 the gear-change pattern is changed
 the CHECK message TRANSMISSION
OVERHEATING can appear on the SID
If TRANSMISSION OVERHEATING
appears on the SID, stop the car as soon as
it is safe to do so and wait until the warning
has been extinguished. When continuing
your journey, select a locked gear (1, 2 or 3)
that will allow you to drive at an engine
speed of about 3,000 rpm (see page 161). Do not drive continuously with the WINTER
mode selected in hilly country when you are
towing a trailer, as this will increase fuel con-
sumption and risk overheating the transmis-
sion.
Driving considerations Always take extra care when towing a
trailer, as the car’s handling will be different
and its braking effect reduced. The trailer’s
braking system and suspension also have a
considerable effect on these characteris-
tics, see also ”Driving with a load” page 178.
If the car is equipped with automatic trans-
mission, select position L when ascending
or descending steep hills.
Trailer hitch loadThe weight distribution on the trailer makes
a lot of difference to the handling properties
of the car and trailer combination. As
regards single-axle trailers, whenever pos-
sible, concentrate the load over the wheels
and keep it as low as possible.
The trailer should be loaded so that the
maximum load on the towbar ball is 5% to
7% of the trailer weight with a maximum per-
missible tongue weight of 165 lbs. (75 kg).
Note that this load must be added to the total
load for the car. If this now exceeds the
specified load capacity, the load in the lug-
gage compartment will have to be reduced
by a corresponding amount.
WARNING
Remember to use engine-braking (selec-
tor position L, 3, or 4) to spare the brakes
when you are driving on a long or steep
downhill slope.
Brake failure can result from overheated
brakes!
NOTEIf the ”Automatic transmission, fault indi-
cator” indicator comes on, cease
towing until the problem has been recti-
fied.

178 Starting and drivingDriving with a loadThe driving characteristics of the car are
affected by the way it is loaded.
 Place heavy loads as far forward and as
low as possible in the trunk.
 Secure the load to the tie downs, see
page 134.
 The load should be such that the car´s
total weight or axle weight are not
exceeded, see page 248.
 Heavy loads mean that the car’s center of
gravity is further back. As a result, the car
will sway more during evasive steering.
 Never exceed the permissible load in the
roof box, even if there is room for more.
 Ensure that the tire pressure is correct –
slight overinflation is preferable to under-
inflation.
 The braking distance of a loaded car is
always greater. Keep your distance from
the vehicle in front.
 Roof loads can negatively affect tele-
communication.
Tire pressure, see page 257 and back
cover.
TiresThe tire pressure should match the current
load and speed of the car; see the back
cover or the tire pressure label on
page 257.
The tire pressures given apply to cold tires,
that is tires that are the same temperature
as the outside air temperature.
The tire pressure increases as the tires
become warm (e.g. during highway driving)
with approximately 0.3 bar (4 psi). When
the temperature of the tires changes by 50°
(10°C), the tire pressure will change 0.1 bar
(2 psi).Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
Underinflated tires wear more quickly than
slightly overinflated tires.
If a valve is leaking, simply unscrew it and fit
a new one.
Important! Remember to adjust the tire
pressures if you change the load in the car
or intend to drive at substantially lower or
higher speeds than normal.NOTECheck the tire pressure at least once a
month. Underinflation is the main cause
of:
 Damage to the wheels.
 Premature tire wear.
 Damage to the sidewalls.

197 Car care and technical information
Brake and clutch fluid Checking the fluid level The combined brake and clutch-fluid reser-
voir is transparent to facilitate checking of
the fluid level.
The level should be between the MAX and
MIN marks. Top up, as necessary, with
DOT 4 fluid. Do
not
use DOT 5 brake fluid.
Use only new brake fluid from a sealed con-
tainer.
Check that there are no leaks in the brake
system.
The brake fluid level will fall somewhat as
the brake pads wear. The MAX level in the
reservoir corresponds to the amount of
brake fluid required with new brake pads. If
the fall in fluid level is moderate, due to
normal brake pad wear, topping up is not
necessary.
Changing of the brake fluid should be
carried out by an authorized Saab dealer.The vehicle´s regular braking system is
adjusted automatically, but the parking
brake has to be adjusted manually. This
work, involving adjustment of the parking
brake cables and brake pads, must only be
carried out by an authorized Saab dealer.
It is not possible to detect, through abnormal
pedal or parking brake-lever travel, whether
brake pads are worn and need replacing. It
is therefore essential that brake pads be
checked regularly, as specified in the ser-
vice program.
Brake pad wear indicators The outboard brake pads on the front
wheels incorporate pad-wear indicators.
When the lining is down to 0.11 in (3 mm),
the pad will produce a screeching, squeal-
ing or scraping noise when the brakes are
applied. New pads should be fitted without
delay.
Brake pads should only be changed by
an authorized Saab dealer. To ensure
optimum brake performance, use only
Saab original brake pads.
WARNING
Brake fluid deteriorates as it becomes
old. Because it is hygroscopic, it absorbs
water from the air and, in time, could allow
vapor to form in the brake system, thus
reducing its performance. It is therefore
important that brake fluid be changed reg-
ularly, as specified in the service pro-
gram.
NOTEAvoid spilling brake fluid onto paintwork,
since it can cause the paint to bubble and
lift. If any brake fluid is spilled, the area
should be flushed with large quantities of
water as quickly as possible.

222 Car care and technical informationWheels Alternative wheels and tiresIf you wish to fit other tires or wheels than
those supplied with the car, consult your
Saab dealer first as to the possibilities avail-
able.
Wheels/tires combinations that are not
approved by Saab can negatively affect the
car´s directional stability, steering and brak-
ing in both wet and dry conditions.
Do not assume that a wheel/tire combina-
tion will function properly just because it will
bolt on.
The wheels and tires have been carefully
matched to the characteristics of the car and
play a key role in its outstanding roadhold-
ing and handling.
To ensure that the speedometer is as accu-
rate as possible it should be reprogrammed
if wheels of a different dimension are fitted.
Contact an authorized Saab workshop.
Tire pressureTires need to be inflated to suit the load car-
ried and the maximum speed the car will be
driven (see the recommended tire pres-
sures on the back cover). Note that all
values apply to cold tires. For tires with an
aspect ratio less than /60, increase the tire
pressure by 3 psi (20 kPa) for rough roads
with potholes to minimize the risk of rim
damage.
Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
Soft tires will cause faster wear than
over-pressurized tires. They also increase
fuel consumption.
If a valve is leaking, simply unscrew it and fit
a new one.
Important! Remember to adjust the tire
pressures if you change the load in the car
or intend to cruise at a substantially higher
or lower speed than normal.
NOTEAlways consult your Saab dealer before
changing the wheels and tires on your
Saab.
For wide wheels and/or low-profile tires,
bear in mind the following:
 Tires and wheels can be damaged in
potholes etc.
 Springs, shock absorbers and wheel
bearings and body mountings can be
overloaded.
 The wheels can come into contact with
chassis and body components.
 The speed and load limits for the tires
must not be exceeded; see page 223.
 Wheels larger than 17” must not be fit-
ted. The maximum permissible offset
is 49 mm.
 Tire and wheel size can affect the
function of the Electronic Stability
Program (ESP).
NOTECheck the tire pressures at least once
per month.
Underinflation is the main cause of:
 Tires wearing out prematurely.
 Damage to the sidewalls.
 Damage to the wheels.

226 Car care and technical informationCompact spare wheelThe compact spare is light and easy to
handle when changing the tire. Its use is
only permitted when a standard tire has sus-
tained a puncture. The maximum life of the
tire is only 2000 miles (3,500 km).
Do not exceed 50 mph (80 km/h) with the
compact spare fitted.
The compact spare should be inflated to
60 psi (420 kPa). Carry the punctured tire in
the spare-wheel well under the luggage-
compartment floor.
Have the standard tire repaired and refitted
as soon as possible (see also page 179).The spare wheel, together with the jack ,
front towrope attachment eye and toolkit, is
stowed away underneath a panel in the lug-
gage-compartment floor. The jack handle is
kept in a cover beside the spare wheel.
If you need to change a wheel, remove the
tool kit first and then the spare wheel.
The panel over the spare wheel can be held
open by hooking the handle onto the rubber
seal.
NOTETo avoid damaging a punctured alloy
wheel it can be placed outside up in the
spare-wheel well but only while driving to
the closest workshop.
A general rule is that all heavy loads must
be well secured in the luggage compart-
ment, see page 134 and 137.

Changing a wheel
WARNING
 The car jack is designed solely for use
in changing a wheel or fitting snow
chains. It must not be used to support
the car during repair work or servicing.
 Never crawl under a car that is
supported only by a jack.
 Special care must be taken if the car is
on a slope – use wheel chocks!
 Position chocks, one ahead and one
behind, the wheel that is diagonally
opposite to the one to be changed.
 Switch on the hazard warning lights if
the car is on a road.
 Apply the parking brake and leave the
car in gear (1st or reverse). Automatic
transmission: move selector to the
P position.
 Ensure that everybody is out of the car
before jacking it up.
 Never start the engine while the car is
jacked up.
 The jack must stand on a firm, level
surface.
 Stow the jack in the place provided for
it under the panel in the floor of the lug-
gage compartment. Secure it properly
to avert injury to passengers in the
event of a crash.
 Do not use the jack for any purpose
other than for jacking up the car.
