169 Starting and driving
Tires
The tire pressure should match the current
load and speed of the car; for cars sold in
U.S. see page 226; for cars sold in Canada
see page 261.
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 as the tires
become warm (e.g. during highway driving)
with approximately 0.3 bar (4 psi). When
the temperature of the tires changes by 50°
(10°C), the tire pressure will change 0.1 bar
(2 psi).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.
Important!
Remember to adjust the tire
pressures if you change the load in the car
or intend to drive at substantially lower or
higher speeds than normal.
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.

185 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 ope-
ning duration, ignition timing and turbochar-
ger 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 rele-
ased into the atmosphere. The hydrocar-
bons are absorbed in a evaporative emis-
sion canister. When the engine is
subsequently started, the evaporative emis-
sion canister is gradually purged as air is
sucked into it through a shut-off valve. The
hydrocarbon/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 138.
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.
