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,

The battery should recharge after driving a few
miles and the message should go out. If this message appears while
driving or after starting your vehicle and stays on, have
it checked
immediately to determinethe cause of this problem. To help the
generator recharge the battery quickly,
you can reduce the load on the
electrical system by turning

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

your engine and have it serviced before driving it again. Severe engine
damage can result from an overheated engine. See “Engine Overheating”
in the Index.
ENGINE HOT - A/C COMPRESSOR OFF - 16

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

receives an incorrect feedback from the system, an error code
will be set
in memory and a “SERVICE RIDE CONTROC’ message will display on
the Driver Information Center. If this message should appear, have your
vehicle serviced at your Cadillac dealer at your earliest convenience.
Oil Life Indicator
This feature lets you know when to change your engine oil. It’s based
upon the engine oil temperatures and your driving patterns.
To see the display, press the Information button several times until
“XXX
OIL LIFE LEFT” appears.
You’ll
see how much oil life you have left, as a percentage. So, if you see
“95 OIL LIFE LEFT,” for example, that means that the way you’re
driving your car,
95% of your current oil life is still left.
The Oil Life Indicator may say
to change the oil sooner than your
maintenance schedule. This can happen
if driving conditions, such as
short trips
in cold weather, cause shorter oil life. Always keep a written
record of the mileage and date when you last changed your oil. For more
information on when to change your oil, see the Cadillac Maintenance
Schedule Booklet.
If you
see “CHANGE OIL SOON,” it means that you have less than 10%
of your oil life left, and you should consider changing your engine oil.
If you see “CHANGE ENGINE OIL,’’ it means the oil
life is gone and
you should change the oil right away (certainly within 200 more miles
[320 km]).
