Cruise Control - Chevrolet 4500 HD 2023 Manual

Warning (Continued)
When the ESC warning light is
flashing, the road surface is slippery,
or acceleration is too fast. Ease up on
the accelerator pedal and drive
conservatively.
The ESC warning light may also flash
when the driver fully depresses the
accelerator pedal on roads that are
not slippery such as dry asphalt roads.
Even with ESC model, when driving on
a snowy or icy road, install tire chains
or winter tires, and drive the vehicle
carefully.
When tire chains are installed, it may
be easier for you to start the vehicle
to move on an icy slope if just the
ASR is canceled.
If there is significant wear or
degradation on parts related to the
suspension, tires, brakes, etc., the ESC
warning light may turn on. In such
cases, ESC may not function properly.
Have your vehicle inspected/repaired
at the dealer.

Cruise Control

The cruise control function allows you to
drive the vehicle at a constant speed
without operating the accelerator pedal. Use
this function when the vehicle speed is
above 40 km/h (25 mph). This function
should only be used when driving without
frequent starts and stops.
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. You
and others could be seriously injured.
Cruise control can be dangerous on
slippery roads. On such roads, fast
