This message is displayed when the
brake fluid level is low; seeBrake
Fluid on page 10-22.
HILL START ASSIST ACTIVE
This message is displayed when the
vehicle is stopped on a grade
sufficient to activate HSA. HSA
holds the braking pressure for a
maximum of two seconds to ensure
that there is no rolling, which will
assist the driver to transition
between releasing the brake pedal
and accelerating to drive off while
on the grade. The brakes will
automatically release when the
accelerator pedal is applied within
the two-second window. See Hill
Start Assist (HSA) on page 9-42.

This message is displayed as a
reminder that the parking brake is
on. Release it before you attempt
to drive.
SERVICE BRAKE ASSIST
This message may be displayed
when there is a problem with the
