9-5
Saab Parking Assistance, SPA (Available on Arc and Aero)
Brief description
To facilitate reversing and parking, the Saab 9-5
(Sedans and SportWagons) can be equipped
with Saab Parking Assistance (SPA). SPA will
be available in an option package on Arc and
Aero models in the U.S. market for model year
2002.
SPA measures and indicates the distance to the
closest object behind the vehicle. The distance
is indicated via the SID (Saab Information
Display) in the form of acoustic signals (beeps)
in addition to the message “PARK ASSIST”
displayed on SID.
While the vehicle is reversing, as it gets closer to
an object, the signal (beeps) from the SID
become more frequent (more signals per unit of
time). In this way the driver can avoid damage to
the vehicle when reversing (e.g. when parking).
SPA is activated only when the reverse gear is
selected.
In the Sedan variant, the control module is
located behind the backrest member, under the
side trim on the left-hand side.
In the SportWagon variant, the control module is
located under the front floor in luggage
compartment.
The four distance sensors use ultrasound to
measure the distance to the closest object
behind or alongside the car. The sensors are
located in the rear bumper and are named as
follows:
• Left-hand outer distance sensor (RL)
• Left-hand center distance sensor (RLC)
• Right-hand center distance sensor (RRC)
• Right-hand outer distance sensor (RR)
(Note that this system will not be available until
February, 2002)
