Cruise Control

Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
With cruise control a speed of about
40 km/h (25 mph) or more can be
maintained without keeping your
foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
See Tow/Haul Mode Grade
Braking under Tow/Haul Mode
0 227 for an explanation of how
cruise control interacts with the
Range Selection Mode, Tow/Haul
Mode, and Grade Braking systems.

and the Traction Control system
(TCS) begins to limit wheel spin, the
cruise control will automatically
disengage. When road conditions
allow you to safely use it again,
cruise control can be turned
back on.
If the brakes are applied, cruise
control disengages.
