lights up under the speedometer if:
• a fault has been detected and the system
has therefore been switched off
• the system has been switched off
manually
ESP indicator light
When the remote control is turned to the ON
position, the lamp is lit for about 4 seconds
while the system performs self-diagnosis.
The light under the speedometer
comes on for a short period of time when the
ESP system is operative.
Operation of the ESP indicates reduced
cohesion between the tires and the road,
and that extra care should be taken by the
driver.
Turning ESP system off
The system can be turned off manually with
the ESP button, whereupon the
under the speedometer will come on. The
car must be travelling slower than 35 mph
(60 km/h). The TCS is also disengaged.
The ESP is always engaged during braking,
even if it has been switched off manually
with the ESP button.
If a fault is detected in the system, the
following message will be displayed on
the SID:
Stability control failure.
Contact Saab dealer.
The cruise control system (if active) will
automatically be disengaged if the ESP is
operative.
NOTICE
Changes to the chassis, such as a
change of wheels, shock absorbers or
light
springs, could affect the function of the
ESP system.
Always consult your Saab dealer before
changing any chassis components.
