your vehicle (especially during cold winter weather), and
begin to drive away (up to 6 mph (10 km/h)), the
message ACT HNDLG – WARMING UP may be

UP COMPLETE is displayed in the DIC.
During hot or cold temperature conditions, this message
may be displayed in the DIC after exceeding 12 mph

off until the WARM UP COMPLETE message is

Active Handling Systems are off, pressing the Active
Handling System console button momentarily will

TRAC/ACT HNDLG – OFF: By pressing the Active
Handling System console button briefly, the driver can

The Traction Control System will not be operating
while in the Competitive Driving mode. You should

SERVICE ABS (Anti-Lock Brake System): If the
SERVICE ABS message is displayed when you
are driving, stop as soon as possible and turn the
ignition off. Then start the engine again to reset the
system. If the message stays on, or comes back
on again while you are driving, your vehicle is in need
of service. If the regular brake system warning light isn't
on, you still have brakes, but don't have anti-lock
brakes. If the regular brake system light is also on, you
don't have anti-lock brakes and there is a problem
with your brakes. See Brake System Warning Light on
page 3-35 .
