2004 SAAB 9-5 wheel

182 Starting and drivingTrailer 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
permissible tongue weight of 110–165 lbs.
(50–75 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
When you connect the trailer be sure to
attach its safety chains to the holes as
illustrated.

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 possi-
ble.
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
 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 279.
 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 137 and 140.

Front 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 lever-
age.
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 seriously 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.

190 Starting and drivingTowing the car Gear lever in neutral (in cars with automatic
transmission: selector lever at N (neutral))
Turn on the parking lights.
Drive carefully and do not exceed the
speed limit for vehicles being towed.
Always try to keep the towrope taut by
gently applying the brake, as necessary.
This will avoid the towrope being jerked
violently.
The local regulations on towing speeds
must be followed.
The highest permissible towing speed is
30 mph (50 km/h), unless the legal limit is
lower. The longest permissible towing dis-
tance is 30 miles (50 km). If the car has to
be transported farther than that, summon a
tow truck. A flat bed tow truck is the pre-
ferred method to tow.
Failure to follow these guidelines can result
in damage.Cars with automatic transmission
The car cannot be bump started. In an
emergency, it is possible to start the engine
using jump leads (see the section, ”Jump
starting” on page 191).
Transporting the car
NOTICE
Never 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.
NOTICEIf a car with a sport (lowered) chassis is
transported, for example on a flat bed
truck, take extra care not to damage the
spoiler and/or underbody.
Never use the towing eyes to pull the car

196 Starting and drivingParking brake

The parking brake is situated between the
front seats and acts on the rear wheels.
When the parking brake is on, the indicator
light on the main instrument panel will
be on. To release the parking brake, lift the
lever slightly, press the release button and
release the lever by pushing down on it.
Parking
WARNING
Always apply the parking brake when
you park the car.
Always apply the parking brake
before removing the ignition key.
 Do not use the parking brake while
driving.
WARNING
 Do not leave children or pets unat-
tended in the car. In warm, sunny
weather, the temperature inside the
car can reach 160–180°F (70–80°C).
 Park where the vehicle will not create
an obstruction or a hazard to other
road users.
 Do not park on dry grass or other com-
bustible material. The catalytic con-
verter gets very hot and could start a
fire.
 Apply the parking brake.
 Shift to Reverse for manual transmis-
sion (automatic transmission: move
selector lever to P (Park)), and remove
the ignition key. Lock the car.

197 Starting and driving
Parking on a hillWhen parking on a steep hill, turn the front
wheels so that they will be blocked by the
curb if the car should move. Long-term parkingIf the car is not going to be used for some
time, e.g. 3–4 months, the following steps
are recommended:
 Run the engine to normal temperature
before long-term parking.
 Drain the washer-fluid reservoir and
hoses.
 Wash and wax the car. Clean the rubber
seals on the hood, luggage compartment
lid and doors, and lubricate them with
glycerol (glycerin).  After washing the car, dry the brake discs
by taking the car out on the road and
applying the brakes a few times.
 Fill the fuel tank with fuel to prevent con-
densation forming in it.
 Top up the coolant and check the anti-
freeze before the onset of winter.
 Park the car in a dry, covered and
well-ventilated building. Leave the park-
ing brake OFF!
 Disconnect the negative (–) battery lead.
If frost is likely to occur during the long-term parking, remove the battery
and store it away from the frost.
 Ideally, the car should be put up on blocks,
with the wheels off the ground. If this is not
possible, inflate the tires to about 43 psi
(300 kPa).
 Leave all the windows open a crack and
cover the car with a fabric tarpaulin – not
one made of plastic.NOTICEEmpty the car yourself and bear in mind:
 Never leave a mobile phone, camera,
computer or similar object visible in
your car.
 Clothing, packages and bags attract
thieves.
 Do not leave small objects such as
CDs, sunglasses and coins visible.
 If possible, park in a well-lit,
conspicuous parking space.
 Thieves strike whenever and wher-
ever they are given the opportunity.

203 Car care and technical information
ORVR (Onboard Refueling Vapor
Recovery)Hydrocarbon vapors formed when refueling
will be recovered by the car and not
released into the atmosphere. The hydro-
carbons are absorbed in a evaporative
emission canister. When the engine is sub-
sequently started, the evaporative emission
canister is gradually purged as air is sucked
into it through a shut-off valve. The hydro-
carbon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked at least 3 times. Otherwise, it is pos-
sible for the CHECK ENGINE light to illumi-
nate and a ”Tighten fuel filler cap.” message
to appear on SID.
Refueling, see page 154.
EngineThe 2.3-liter model is a transverse, 4-cylin-
der in-line engine with twin overhead cam-
shafts and 4 valves per cylinder.
This engine is equipped with balance shafts
that reduce engine vibration to a minimum.
The balance shafts are chain driven and
rotate at twice the speed of the crankshaft.
They produce forces and torques that are
opposed to those generated by the pistons
and connecting rods, an effect that occurs
twice for each revolution of the engine.
Engine noise is also reduced as the
counter-rotating shafts counteract the vibra-
tion from the moving parts of the engine.The transmission, located on the right
(viewed from the front), is integrated with
the engine. All models have front-wheel
drive.

208 Car care and technical informationBrake 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.
NOTICEAvoid 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.
