2005 SAAB 9-5 coolant temperature

180 Starting and drivingParking 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 gly-
cerol (glycerin).
 After washing the car, dry the brake discs
by taking the car out on the road and app-
lying 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 parking
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.

1Pointing downhill and
against the curb– Turn the wheels into
the curb and edge the
car forward until the
wheels touch the curb.2
Pointing uphill and
against the curb– Turn the wheels away
from the curb and edge
the car back until the
wheels touch the curb.3
Pointing uphill or
downhill – no curb– Turn the wheels
towards the edge of the
road. If the car should
start rolling, it will not run
into the road.

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.

189 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 appro-
ved 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 pro-
perties are no longer retained and the coo-
lant 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
regularly, as specified in the service
program.
