2000 SAAB 9-5 wheel torque

147 Starting and driving
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!
That 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 practicing the use of ABS
brakes on a skid pan or other suitable facil-
ity.
Traction Control SystemHow the system works The traction control system (TCS) is
designed to prevent 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

170 Car care and technical informationORVR (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 134.
Engine2.3-liter 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.
3.0-liter V6 engine The 3.0-liter engine is a transverse, V6
engine with each bank of cylinders having
double overhead camshafts and 4 valves
per cylinder.
The transmission, located on the right
(viewed from the front), is integrated with
the engine. All models have front-wheel
drive.

205 Car care and technical information
4 Wind the jack to raise the wheel clear of
the ground. Remove the wheel bolts and
lift off the wheel.
5 Fit the wheel and screw in the bolts in the
sequence shown (opposite pairs).
Tighten the bolts enough for the bolts
and wheel to be seated correctly.
6 Lower the car and tighten the wheel
bolts to the correct torque in the
sequence shown (opposite pairs).
Tightening torque
Light-alloy wheels: 80 ft.lbs. (110 Nm)
Steel wheels: 80 ft.lbs. (110 Nm)
Do not overtighten the bolts using a per-
cussion nut tightener: not only can this
damage the wheels but it can also make it impossible to undo the bolts using the
wheel wrench in the car’s toolkit.
7 Check-tighten the wheel bolts after a
few miles.
Tightening torque
Light-alloy wheels: 80 ft.lbs. (110 Nm)
Steel wheels: 80 ft.lbs. (110 Nm)
We advise against using wheels with open
wheel covers in winter, as the brake compo-
nents are then more exposed both to slush
and to road salt and grit.
NOTEWhen refitting wheel covers (where
applicable), make sure that the valve
protrudes through the hole in the wheel
cover.
