4 Lower the entire backrest cushion by pulling this same handle
(item 3) forward. At the same time, pivot the beam backwards.
IMPORTANT: When you replace the belt beam using the handle
(item 3), you must verify that it is properly locked and that the two
red "warning tabs" go down (thereby indicating that locking has
taken place properly).
5 To increase the volume, the rear head restraints can be removed
before the backrest cushion is lowered.
Lowering the right-hand part of the rear seat
WARNING
Never leave a child or animal unattended in the car. During sunny
weather the temperature in the cabin/luggage compartment can
climb to 160-180°F (70-80°C). Small children are very susceptible
to heat stroke.
The tail pipe of the exhaust system can become very hot during
driving. Bear this in mind when loading and unloading the car so
that children, for example, do not burn themselves.
WARNING
 If the head restraints have been removed, they must be stored
safely so that they cannot be thrown about and injure someone
while braking or in a crash.
 Do not ride in the rear seat without having remounted the head
restraints, and making sure they are properly locked in place.
 Whenever you handle any system containing moving parts,
such as the belt beam, always be careful not to get pinched.
 Never keep objects on the rear window shelf since they can be
thrown forward and cause personal injury during heavy brak-
ing or in the event of a crash.
 When the back seat has been put back in place, make certain
that the belt beam is locked firmly on both sides (the red warn-
ing tabs must go down). This is vital since the upper anchor-
ages for the safety belts are located in the belt beam.
The
belts will not restrain a rear seat occupant if the belt beam is
not properly latched

140 Interior equipment, trunkTo provide more flexibility, the rear seat is divided so that you can
lower the narrower (right) part separately.
1 Tilt the seat cushion forward by pulling the loop located between
the backrest and the seat cushion.
2 Stand the seat cushion on end behind the front seats.
3 Release the right backrest cushion by means of the latch on the
belt beam’s right side just behind the head restraint.
4 Lower the right backrest cushion.
IMPORTANT: When you replace the right backrest cushion, make
certain that it is properly locked.

165 Starting and driving
ABS brakes ABS (Antilock Braking System) modulates
the brake pressure to the respective
wheels. Wheel sensors detect if a wheel is
about to lock, and the control module
reduces the pressure to that wheel and then
increases it once more until the tendency is
detected again.
The brake system is equipped with an Elec-
tronic Brake-force Distribution device
(EBD), which distributes the brake pressure
between the front and rear wheels in such a
way as to achieve optimum braking per-
formance irrespective of the car’s speed
and load.
The ABS system has a built-in diagnostic
function which will switch on the ABS warn-
ing light if a fault is detected in the system
(see page 62). 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 is
past!
This is critical.
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 practising the use of ABS
brakes on a skid pad or other suitable facil-
ity.
WARNING
 The additional safety afforded by the
ABS system is not designed to allow
drivers to drive faster but to make
normal driving safer.
 To stop as quickly as possible, without
loss of directional stability, whether
the road surface is dry, wet or slippery,
press the brake pedal down hard
without letting up (do not pump the
pedal), declutching simulta-
neously, and steer the car to safety.

166 Starting and drivingTraction Control SystemHow the system works The traction control system (TCS) is
designed to minimize wheelspin. This
enables the car to achieve the best possible
grip and, hence, maximum tractive effort,
together with greater stability.
The TCS system uses information from the
ABS system’s wheel sensors to detect
when the front (driving) wheels are rotating
faster then the rear wheels. It then monitors
whether one driving wheel is rotating faster
than the other. If so, the faster wheel is
retarded until both wheels are rotating at the
same speed.
If the two front wheels are rotating at the
same speed but are turning faster than the
rear wheels, the torque from the engine is
reduced to eliminate the difference.
The process continues until all the wheels
are rotating at the same speed. The advantages of the TCS system become
most apparent when the cohesion between
the front wheels and the road surface is so
low that one or both of the wheels would
lose their grip were the car not equipped
with the TCS, e.g.:
 When the car is pulling away or accelerat-
ing with the front wheels on different sur-
faces (e.g. one slippery and one dry). The
TCS then functions like an electronic dif-
ferential lock.
 When the car is pulling away or accelerat-
ing on a slippery road, in which case the
TCS eliminates wheelspin. The same
applies when the car is reversing.
 On cornering, if there is a tendency for the
inner front wheel to rotate faster than the
other wheels.
 On overtaking.
TCS OFF The indicator on the main instrument
panel will come on:
 If a fault has been detected and the
system has therefore been switched off.
 If there is a fault in the ABS system.
 If the system has been switched off man-
ually.
The indicator light will also come on for
4 seconds when the ignition key is turned to
ON, while an internal system check is per-
formed. TCS indicator The in the tachometer comes on when
the system is operative, i.e. when the
wheels are not rotating at the same speed.
The fact that the TCS system is operative
indicates that the limit for grip has been
exceeded and that the driver must exert
greater care.
WARNING
When driving normally, the TCS helps to
imrove the safety of the car. This does
not mean that car can be driven faster.
The same care and prudence normally
applied should be displayed on corner-
ing and when driving on slippery roads.

167 Starting and driving
Turning the TCS off The is switched on automatically when
the engine is started.
The system can be switched off manually by
the TCS button, whereupon on the
main instrument panel will come on. The
TCS system cannot be switched off if the car
is travelling faster than 35 mph (60 km/h).
It may be necessary to switch off the system
if the car has become bogged down, for
instance. Press TCS to switch it on again.
If a fault is detected in the ABS system, the
TCS will be switched off automatically.
The cruise-control system will automatically
be disengaged after one second if it is active
when the TCS starts to operate.

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.
 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)All hydrocarbons formed when refueling will
be recovered by the car and not released
into the atmosphere. The hydrocarbons are
absorbed in an evaporative emission canis-
ter. When the engine is subsequently
started, the evaporative emission canister is
gradually purged as air is sucked into it
through a shut-off valve. The hydrocar-
bon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned. "Refueling", see page
151.
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.
NOTEThe Trionic engine management system
continuously monitors the operation of
these systems and has on-board diag-
nostic capabilities (OBD II). If the CHECK
ENGINE light in the main instrument illu-
minates, the Trionic ECM has detected a
problem. The car will continue to operate,
but performance may be diminished. You
should have your car checked by a Saab
dealer as soon as possible.

194 Car careBrake- clutch fluid and
brake padsChecking 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.
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 installed with-
out 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.
