Active Handling System
The Active Handling System is a computer
controlled system that helps the driver maintain
directional control of the vehicle in difficult driving
conditions. This is accomplished by selectively
applying any one of the vehicle’s brakes.
When you first start your vehicle during cold winter
weather and begin to drive away, the message
ACTIVE HANDLING WARMING UP may be
displayed in the DIC. This is normal. You can
acknowledge this message by pressing the RESET
button. The Active Handling System performance is
affected until the message, ACTIVE HANDLING
READY, is displayed in the DIC.
The ACTIVE HANDLING CALIBRATING message
may be displayed in the DIC and the instrument
panel cluster light will be on after exceeding 18 mph
(30 km/h) for 10 seconds. The Active Handling
System is off until the ACTIVE HANDLING READY
message is displayed. This could take up to
15 minutes.
The ACTIVE HANDLING message will come on
when the system is operating. See DIC Warnings
and Messages on page 212 for more information.
You may also feel or hear the system working.
This is normal.
The SERVICE ACTIVE
HANDLING message
will be displayed, the
instrument cluster light
will come on, and a
chime will sound to let
you know if there is a
problem with the system.
See DIC Warnings and Messages on page 212 for
more information.
When this light and the SERVICE ACTIVE
HANDLING SYSTEM message are on, the system
is not operational. Adjust your driving accordingly.
