2006 SAAB 9-5 ABS

164 Starting and drivingThe ABS system has a built-in diagnostic
function which will switch on the Anti-lock
brake warning light if a fault is detected in
the system (see page 60).
The ABS system will not reduce the braking
distance on loose gravel or on snow or ice
but, because the wheels cannot lock up,
some steering control is retained.
When the ABS system is working, i.e. mod-
ulation of the brake pressure is in progress,
the brake pedal will pulsate and a ticking
noise will be heard. All this is perfectly nor-
mal.
Press the pedal down hard (you cannot
press too hard) and steer the car to safety.
Do not release the brake pedal before the
car has come to a halt or the danger has
passed!
If the road is slippery, the ABS system will
operate even when only light pressure is
applied to the pedal. This means that you
can brake gently to test the condition of the
road and adapt your driving accordingly.
It is well worth practicing the use of ABS
brakes on a skid pad or other suitable
facility.

165 Starting and driving
Electronic Stability
Program (ESP)The Electronic Stability Program employs
both the antilock braking system (ABS) and
the traction control system (TCS). It is a
system that helps the driver to stabilize the
car in unusual circumstances that would
otherwise be more difficult to handle.
How the ESP system worksThe Electronic Stability Program can help to
prevent the car from skidding by braking
one or several wheels independently of the
driver. The engine output is then also
reduced to prevent the driving wheels from
spinning. The car has sensors that measure
wheel speed, yaw acceleration, lateral
acceleration, steering wheel position and
braking pressure. The values provided by
these sensors are used to calculate the
actual direction of the car. If this direction
does not agree with that intended by the
driver, calculated from the steering wheel
position, the ESP is engaged.
ESP improves the driver’s chances of
retaining control over the car in critical situ-
ations.
To ensure that the system works as
designed, the dimensions of all four tires
must be the same.
WARNING
When driving normally, ESP will help to
improve the stability of the car. This does
not mean that car can be driven faster.
The same care and prudence as normally
applied should be displayed on cornering
and when driving on slippery roads.

195 Car care and technical information
Saab Trionic engine
management systemThe Saab Trionic engine management
system is a unique Saab development that
combines sequential multiport fuel injection,
electronic distributorless ignition and turbo-
charger boost pressure control into one sys-
tem.
The Trionic engine control module (ECM)
monitors many different engine parameters
such as:
 Intake manifold pressure
 Intake air temperature
 Crankshaft position
 Engine coolant temperature
 Throttle position and
 The oxygen content of the exhaust gases.
The ECM receives information regarding
engine knocking from a sophisticated feed-
back function in the ignition discharge unit.
By processing all of this information, the Tri-
onic system can control fuel injector open-
ing duration, ignition timing and turbo-
charger boost pressure to provide excellent
engine performance while maintaining low
emissions and fuel consumption.
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.
Refueling, see page 148.
NOTICEThe Trionic engine management system
continuously monitors the operation of
these systems and has on-board diag-
nostic capabilities (OBD II).
If the ”Engine malfunction (CHECK
ENGINE)” lamp in the main instru-
ment illuminates, this indicates that the
Trionic ECM has detected a problem. The
car will continue to operate, but perfor-
mance may be diminished. You should
have your car checked by a Saab dealer
as soon as possible.

199 Car care and technical information
The cooling system is charged at the factory
with coolant containing a 45 % concentra-
tion of a combined antifreeze and corrosion
inhibitor. A weaker mixture will result in
reduced anticorrosion protection. For pro-
tection against freezing in very cold
weather, a stronger concentration will be
needed.
A 60 % concentration of antifreeze will pro-
vide protection at temperatures down to
–58°F (–50°C).
The coolant does not normally have to be
changed during the service life of the car.
The type of coolant used has a reddish color
and should not be mixed with other types of
coolant. Saab Original coolant should be
used all year round. Only use coolant
approved by Saab.
Note:
If incorrect coolant is used or added, the
life-time properties will be affected. Even if
the coolant is flushed from the system and
replaced with life-time coolant, life-time
properties are no longer retained and the
coolant must then be drained and replaced
at regular intervals.

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.
NOTICEAlways mix the antifreeze with the
appropriate volume of water before
adding it to the cooling system.
If pure antifreeze is added, the engine
could still freeze and be damaged. This is
because the antifreeze will not mix
properly with the coolant before the
thermostat has opened to allow full
circulation.
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.

228 Car care and technical informationBuying New TiresTo find out what kind and size of tires you
need, look at the Tire-Loading Information
label.
If you wish to fit other tires or wheels than
those supplied with the car, consult your
Saab dealer first as to the possibilities
available.
Wheels/tires combinations that are not
approved by the vehicle manufacturer can
negatively affect the car’s directional stabil-
ity, steering and braking in both wet and dry
conditions.
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.
Do not take it for granted that a wheel/tire
combination will work in the best possible
way, just because it can be fitted to the car.
To ensure that the speedometer is as accu-
rate as possible it should be reprogrammed
if wheels of a different dimension are fitted.
Contact a Saab dealer.
Because of front wheel drive, the front tires
tend to wear faster than the rear ones. New
tires should always be fitted in pairs, so that
tires on the same axle have the same
amount of tread.
Store wheels lying flat or hanging – never
standing upright.
NOTICEAlways consult your Saab dealer before
changing the wheels and tires on your
Saab.
Wide wheels and tires with sidewalls that
are too low can:
 be damaged in potholes etc.
 cause springs, shock absorbers and
wheel bearings and body mountings
can be overloaded.
 cause the wheels to come into contact
with chassis and body components.
 can affect the function of the Elec-
tronic Stability Program (ESP).
The speed and load limits for the tires
must not be exceeded; see page 233.
Wheels larger than 17” must not be fitted.
The maximum permissible offset is
49 mm.
WARNING
Mixing tires could cause you to lose con-
trol while driving. If you mix tires of differ-
ent sizes or types (radial and bias-belted
tires), the vehicle may not handle prop-
erly, 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 developed for
use on your vehicle. See “Compact spare
tire” on page 237.
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.

243 Car care and technical information
Upholstery and trimTo remove lint or hairs from the seat uphol-
stery or headlining, use a moist, lint-free
cloth or a special lint remover (brush or
roller). Remove any dirty marks using a
cloth moistened with lukewarm soapy
water.
When using a stain remover, always work
from the outside towards the center to avoid
leaving a ring. If a soiled ring or spot should
remain, it can usually be removed using
lukewarm soapy water or water alone.
Wet patches left by spilled soft drinks or thin
oil must be wiped off immediately using an
absorbent material, such as a paper towel,
and treated with stain remover.
Alcohol is recommended for removing
grease or oil stains, and a semi-stiff brush
may also be used.
Cleaning and caring for
leather upholsteryThe principal reason for treating leather
upholstery is to maintain its elegant appear-
ance and to provide it with a protective film.
Discoloration caused by dust and wear
mainly affects the lighter shades, although
this is not detrimental to the leather –
indeed, the patina resulting from use is often
considered desirable in leather. But if the
leather is allowed to become too grubby, it
can start to look shabby.
It is a good idea to clean and recondition the
leather twice a year – in conjunction with a
general spring-cleaning of the car – after the
winter and in the autumn, for instance. In
hot, dry climates, the leather will need to be
treated more frequently. Use conventional
leather care products. Follow the instruc-
tions on the packaging.
Do not use harsh polishing agents, cleaning
agents, sprays, coarse soap or hot water.
Textile carpetingVacuum clean the carpeting regularly. Car-
pets can also be cleaned using a brush, or
carpet shampoo applied with a sponge. Do
not use vacuum cleaners outdoors unless
they are properly grounded.
