ECU SAAB 9-5 2005 Service Manual

168 Starting and driving
Driving at nightBear in mind the following points when
driving at night:
 Nighttime driving requires your full con-
centration.
 Do not rush. Count on your journey taking
slightly longer.
 The number of drivers under the influence
of drugs is likely to be greater at night than
during the day.
 Do not stare at the headlights of onco-
ming vehicles.
 Avoid driving at night if you have poor eye-
sight. Night vision deteriorates with age.
 Keep your car's headlights, windows and
mirrors clean. Also, if you wear glasses,
make sure they are clean.
 Make sure you are well rested before star-
ting a long journey. Take a break every
other hour.
 Only eat light meals. Heavy meals have a
tendency to induce tiredness.
Driving 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 123.
 The load should be such that the car´s
total weight or axle weight are not
exceeded, see page 252.
 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 262 and back
cover.

170 Starting and drivingSpare wheel and toolsThe spare wheel, together with the jack and
jack handle, front towrope attachment eye
and toolkit, are stowed away underneath
the trunk.
Driving considerations
with compact spare
wheel/tire fitted
The following should be observed when the
compact spare wheel (T115/70 R16) is
fitted:
 The compact spare is light and easy to
handle when changing the wheel.
 Do not drive further than necessary with
the compact spare fitted – the maximum
life of the wheel is only just over
2000 miles (3,500 km).
 Refit the standard tire as soon as pos-
sible.
Important considerations when driving with
a compact spare tire:
 The car’s ground clearance is reduced.
 The car must not be driven with more than
one compact tire at a time.
 Avoid driving against a curb.
 Do not use snow chains.
 Do not fit the wheel cover - this would con-
ceal the warning text.
WARNING
Stow all tools carefully away after use, so
that they cannot get loose and cause
injury in the event of a crash.
WARNING
 Do not exceed 50 mph (80 km/h) as
the tire can overheat and adversely
affect the handling of the car.
 Tire pressure: refer to page 261.
 The spare wheel or punctured tire
must be stowed under the trunk floor,
and secured in place with the retaining
nut.
NOTICETo 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 123 and 126.

172 Starting and drivingFront towing eye
The front towing eye is stored with the spare
wheel.
The attachment point (tapped hole) for the
towing eye is midway along the engine sub-
frame at the front of the car.
Remove the plastic plug and screw in the
towing eye securely.
To ensure that the towing eye is in far
enough, insert the handle of the wheel
wrench through the eye for additional
leverage.
Rear towing eyeThe car has a permanently mounted towing
eye at the back. If the car is equipped with a
trailer hitch, this can be used instead of the
towing eye.
WARNING
 Make sure that the towing eye at the
front is screwed in tightly.
 The towing eye is only designed for
use when the car is being towed on the
road. It
must not be used
to pull the
car out of a ditch, for example.
 Make sure that all bystanders keep a
suitable distance, in case the towing
eye or tow rope should break. The
towing eye or tow rope could catapult
off and cause serious injury.
NOTICE Do not drive the car with the front
towing eye in position. If it catches the
curb, for example, the engine sub-
frame could be damaged.
 Refit the plastic plug in the hole when
the towing eye has been removed, to
keep dirt and moisture out of the
threads.

223 Car care and technical information
Tire Chains
Notice:
If your vehicle does not have
225/45R17 size tires, use tire chains only
where legal and only when you must.
Contact your Saab dealer regarding sui-
table snow chains. Install them on the
front tires and tighten them as tightly as
possible with the ends securely faste-
ned. Drive slowly and follow the chain
manufacturer’s instructions. If you can
hear the chains contacting your vehicle,
stop and retighten them. If the contact
continues, slow down until it stops. Dri-
ving too fast or spinning the wheels with
chains on will damage your vehicle.If a Tire Goes Flat
It’s unusual for a tire to “blow-out” while
you’re driving, especially if you maintain
your tires properly. If air goes out of a tire,
it’s much more likely to leak out slowly. But
if you should ever have a “blow-out”, here
are a few tips about what to expect and what
to do:
If a front tire fails, the flat tire will create a
drag that pulls the vehicle toward that side.
Take your foot off the accelerator pedal and
grip the steering wheel firmly. Steer to main-
tain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blow-out, particularly on a curve, acts
much like a skid and may require the same
correction you’d use in a skid. In any rear
blowout, remove your foot from the accele-
rator pedal. Get the vehicle under control by
steering the way you want the vehicle to go.
It may be very bumpy and noisy, but you can
still steer. Gently brake to a stop – well off
the road if possible.
If a tire goes flat, the next part shows how to
use your jacking equipment to change a flat
tire safely.
WARNING
If your vehicle has 225/45 R17 size tires,
don’t use tire chains, there’s not enough
clearance.
Tire chains used on a vehicle without the
proper amount of clearance can cause
damage to the brakes, suspension or
other vehicle parts. The area damaged by
the tire chains could cause you to lose
control of your vehicle and you or others
may be injured in a crash.
Use another type of traction device only if
its manufacturer recommends it for use
on your vehicle and tire size combination
and road conditions. Follow that manu-
facturer’s instructions. To help avoid
damage to your vehicle, drive slowly,
readjust or remove the device if it’s
contacting your vehicle, and don’t spin
your wheels.
If you do find traction devices that will fit,
install them on the front tires.

230 Car care and technical informationCompact spare tireThe 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 170).The spare tire, together with the jack, front
towrope attachment eye and toolkit, is
stowed away underneath the luggage-
compartment floor.
NOTICETo avoid damaging a punctured alloy
wheel it can be placed outside up in the
spare-wheel well but
only
while driving to
the closest dealer.
A general rule is that all heavy loads must
be well secured in the luggage compart-
ment, see page 123 and 126.
