vehicles will have a number after each message. This number helps to
identify that message, which is only displayed in English.

This message shows that the electrical charging system is overcharging,
(more than 16 volts).
To avoid being stranded have the electrical system
checked by your Cadillac dealership at your earliest convenience.
You can
reduce the charging overload by using the accessories. Turn on the lights,

voltage on the Driver Information Center by toggling
the
“INFORMXTION” button. The normal range is 11.5 to 15.5 volts.
CHECK BRAKE FLUID - 37
This message is displayed to inform the driver that the brake reservoir

Speed Sensitive Steering (SSS)
This system varies the amount of steering effort proportionate to your
vehicle speed. Steering is easier at a lower speed for increased
maneuverability and parking ease.
As your vehicle speed increases, the
steering effort is also increased proportionately. At highway speeds the
amount
of steering effort is greatly increased to provide a manual like
steering feel for maximum control and enhanced vehicle stability.
Speed Sensitive Suspension
The Speed Sensitive Suspension automatically controls the ride of your
vehicle. The system controls damping forces in the shock absorbers and
struts in response to various speed and road conditions. There are three
dampening modes: Comfort, Normal and Firm. As the vehicle speed
increases, the firmness of the suspension increases. The system is in the
Comfort mode, for speeds less than
40 mph (65 km), normal mode for
speeds between 40 mph
(65 km) and’70 mph (110 km/h), and firm for
speeds greater than 70 mph
(1 10 km/h). The system also stiffens damping
during hard acceleration, braking and cornering for increased control.
The Speed Sensing Suspension controller is a computer used to control
and monitor the system. The computer receives inputs from acceleration
and determines optimum mode strut valving
(or suspension stiffness) for
your current operating conditions. The computer also receives feedback
