warning light SAAB 9-3 2003 Service Manual

157 Starting and driving
Towing a trailerMake 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 attachmentTrailer hitch attachments are available as
accessories. These are designed for a max-
imum trailer weight of 3500 lbs (1588 kg),
with trailer brakes.
An electrical socket is provided for connect-
ing the trailer electrics. This is located under
the floor trim by the left-hand tail light.
The Saab genuine electrical socket enables
the battery in the trailer on tow to be charged
during while driving. 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 towbar that is
designed and tested for your Saab.
 Contact your Saab dealer for advice on
which towbar is designed for your car.
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
prevent 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
otherwise 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 attachment.
NOTICE Use only a genuine Saab trailer hitch,
since other models can damage the
car’s bodywork and electrical system.
 Consult 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 18" wheels.

159 Starting and driving
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. As
regards 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 1, 2, or 3) to spare the brakes
when you are driving on a long or steep
downhill slope.
Overheating can cause the brakes to
fade!

162 Starting and drivingDriving with a loadThe handling characteristics are affected by
how the car is loaded.
 Place the heaviest load as far forward and
as low as possible in the trunk.
 Secure the load to the lashing eyes (see
page 118).
 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 of 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.
 Do not exceed the car’s permissible
gross vehicle weight or axle load (see
page 236).
 Roof loads can negatively affect telecom-
munication.
TiresNote: Low tire pressure also causes prema-
ture tire wear and increased fuel consump-
tion.
Tire pressure should match the current load
and speed of the car (see page 245).
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 approximately
4 psi/27 kPa as the tires become warm (e.g.
during highway driving). When the temper-
ature of the tires changes by 50°F (10°C),
the tire pressure will change 2 psi/13 kPa.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.
Note: Remember to adjust the tire pres-
sures if you change the load in the car sig-
nificantly or intend to drive at substantially
lower or higher speeds than normal.
Automatic tire pressure monitoring, see
page 207.
WARNING
Check the tire pressure at least once a
month and before long journeys. Under-
inflation can result in:
 punctures
 separation of the tire and tread
 damage to the sidewalls
 damage to the rims on poor roads
 poor handling characteristics
 premature tire wear
 increased fuel consumption.

165 Starting and driving
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.
Towing the carEngage neutral (automatic transmission:
move the selector lever to N). Turn on the
parking lights.
Engage neutral (automatic transmission:
move the selector lever to N). Turn on the
hazard warning lights.
Drive carefully and do not exceed the
speed limit for vehicles on tow.Always try to keep the towrope taut by
gently applying the brake of the car on tow,
as necessary. This will avoid the towrope
being jerked violently.
Cars with automatic transmission:
Always observe the speed limit for vehicles
on tow. Whatever 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 168.NOTICENever use the towing eyes to pull the car
unstuck.
NOTICE The car must be towed front first.
 If the car is to be towed with the front
wheels off the ground, make sure the
parking brake is off, as this acts on the
rear wheels.
Rear towing eye
Never use the towing eyes to pull the car
unstuck.

167 Starting and driving
Driving with the
compact spare wheelObserve the following when the compact
spare wheel is fitted:
 The compact spare is light and easy to
handle when changing a wheel.
 Do not drive further than necessary with
the compact spare fitted - the maximum
life of the wheel is only just over
2,000 miles (approx. 3,500 km).
 Refit the standard wheel as soon as
possible.Important considerations when driving with
a compact spare wheel:
 The car’s ground clearance is reduced.
 The car must not be driven with more than
one compact spare wheel at a time.
 Avoid driving against the curb.
 Do not use snow chains.
 Do not fit the wheel cover - this would
conceal the warning text.
WARNING
 Do not exceed 50 mph (80 km/h). The
tire can overheat affecting the car’s
roadholding.
 Tire pressure: refer to page 243.
 The spare wheel or punctured wheel
must be stowed under the trunk floor,
and secured in place with the retaining
nut.
NOTICETo avoid damaging a punctured alloy
wheel, this can be temporarily placed
outside up in the spare wheel well but
only while driving to the closest work-
shop.
As a general rule, all heavy loads must be
well secured in the trunk (see page 118).

169 Starting and driving
3 Turn off the ignition on both vehicles.
Turn off all lights that are not needed,
and radios. This will avoid sparks and
help save both batteries and it could
save your radio.
4 Open the hood and locate the battery.
Find the positive (+) and negative (–) termi-
nals on the battery.
5 Check that the jumper cables do not
have loose or missing insulation. If they
do, you could get a shock and also the
vehicles could be damaged.
Before you connect the cables, here are
some basic things you should know.
Positive (+) will go to positive (+) and
negative (–) will go to negative (–). Do
not connect (+) to (–) or you will get a
short that could injure you or would
damage the battery and maybe other
parts as well.
6 Connect the red positive (+) cable to the
positive (+) terminal of the vehicle with
the discharged battery.7 Do not let the other end touch metal.
Connect it to the positive (+) terminal of
the good battery. Use a remote positive
(+) terminal if the vehicle has one.
8 Now connect the negative (–) cable to
the good battery’s negative terminal.
9 Attach the cable to the discharged
battery’s negative terminal.
10 Start the vehicle with the good battery
and run the engine for a while.
11 Try to start the vehicle with the
discharged battery. If it does not start
after a few tries, it probably needs
service.
12 Remove the cables in reverse order to
prevent electrical shorting. Take care
that they do not touch each other or any
other metal.NOTICEIf you leave your radio on, it could be
badly damaged. The repairs would not be
covered by your warranty.
WARNING
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.
WARNING
Using a match or flame of any kind near a
battery can cause battery gas to explode.
You can suffer burns or be blinded. Use a
flashlight if you need more light.
Be sure the electrolyte in the battery is not
frozen. Discharged batteries will freeze.
When connecting jumper cables to a
frozen battery, gas from the chemical
reaction inside the battery can build up
under the ice and cause an explosion.
Battery fluid contains acid that can burn
you. Do not get it on you. If you acciden-
tally get it in your eyes or on your skin,
flush the area with water and get medical
help immediately.

188 Car careChanging bulbsAutochecking of lightsThe bulbs that are most important from the point of view of traffic
safety are monitored by the car’s electrical system. If one of these
bulbs should fail, a message will be displayed on the SID.
Example of SID message:
The following bulbs are not checked: parking lights, front fog lights,
reversing lights, license plate lighting, side marker lights and side
direction indicators.If a brake light bulb fails
If a brake light bulb fails, the adjacent tail light will act as a brake light
to ensure traffic safety. Change the broken bulb when possible.
All rear light bulbs are of the same type and rated 21 W, with the
exception of the license plate lighting which is rated 5 W.
Wrong bulb fitted
If a dipped or main beam bulb of too high a rating is fitted, a bulb
failure message will be shown on the SID (a too high wattage bulb
can damage the reflector).
If the following message is displayed but the bulb shines, it is most
likely that an incorrect bulb has been fitted.
Note:
When changing bulbs, fit the same type of bulb (e.g. Long-Life)
as that removed.
Headlight aiming, page 226.
WARNING
Before changing a bulb in the engine bay, switch off the engine
to avoid the danger of fingers and hands being injured by moving
parts.
The radiator fan can cut in even when the engine is switched off.NOTICESwitch off the ignition before changing a bulb, to avoid possible
short-circuiting.

Bi-Xenon headlight, main and dipped beam (certain
variants only)Xenon headlights produce roughly three times as much light as
halogen bulbs and have a significantly longer service life.
The lamp units consist of a gas discharge lamp containing xenon.
When the lights are switched on a very high voltage activates the
xenon gas. The lamps soon reach full intensity.
Cars with Bi-Xenon headlights have automatic levelling. The level-
ling system comprises two sensors, one on the front suspension and
one on the rear suspension, and a control unit by the engine bay fuse
box. Headlight alignment is adjusted automatically to the car’s load
to prevent dazzling drivers in oncoming traffic.
If a fault is detected in the system, the following message will be dis-
played on the SID:
WARNING
Bi-Xenon headlights are high tension. All work on Bi-Xenon head-
lights, including changing bulbs, must be carried out by dealer
personnel.
