2021 Chevrolet Silverado 2500HD Owners Manual - Cruise Contro



Cruise Contro

If equipped 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).

If the cruise control is being used and the Traction Control System (TCS) or StabiliTrak/ Electronic Stability Control (ESC) begins to limit wheel spin, the cruise control will automatically disengage. See Traction Control/Electronic Stability Control 0 242.

If a collision alert occurs when cruise control is activated, cruise control is disengaged. See Forward Collision Alert (FCA) System 0 257.

When road conditions allow you to safely use it again, cruise control can be turned back on.

Turning off the TCS or StabiliTrak/ESC system will disengage the cruise control.

If the brakes are applied, cruise control disengages.

5 : Press to turn cruise control on or off. A white indicator comes on or off in the instrument cluster.

+RES : If there is a set speed in memory, press the control up briefly to resume to that speed or press and hold to accelerate. If cruise control is already engaged, use to increase vehicle speed.

SET− : Press the control down briefly to set the speed and activate cruise control.

If cruise control is already engaged, use to decrease vehicle speed.

* : Press to disengage cruise control without erasing the set speed from memory.

Setting Cruise Control

If 5 is on when not in use, SET− or +RES could get pressed and go into cruise when not desired. Keep 5 off when cruise is not being used.

    Press 5 to turn the cruise system on.
    Get up to the desired speed.
    Press and release SET−.
    Remove your foot from the accelerator.

The cruise control indicator on the instrument cluster turns green after cruise control has been set to the desired speed. See Instrument Cluster 0 102.

Resuming a Set Speed

If the cruise control is set at a desired speed and then the brakes are applied or * is pressed, the cruise control is disengaged without erasing the set speed from memory.

Once the vehicle reaches about 40 km/h (25 mph) or more, press RES+ up briefly. The vehicle returns to the previously set speed.

Increasing Speed While Using Cruise Control

Do one of the following:

    Press and hold +RES up until the desired speed is reached, then release it.
    To increase vehicle speed in small increments, press +RES up briefly. For each press, the vehicle goes about 1 km/h (1 mph) faster.

The speedometer reading can be displayed in either English or metric units. See Instrument Cluster 0 102. The increment value used depends on the units displayed.

Reducing Speed While Using Cruise Control

Do one of the following:

    Press and hold SET– down until the desired lower speed is reached, then release it.
    To slow down in small increments, press SET– down briefly. For each press, the vehicle goes about 1 km/h (1 mph) slower.

The speedometer reading can be displayed in either English or metric units. See Instrument Cluster 0 102. The increment value used depends on the units displayed.

Passing Another Vehicle While Using Cruise Control

Use the accelerator pedal to increase the vehicle speed. When you take your foot off the pedal, the vehicle will slow down to the previously set cruise speed. While pressing the accelerator pedal or shortly following the release to override cruise control, briefly pressing SET– will result in cruise control set

to the current vehicle speed.

Using Cruise Control on Hills

How well the cruise control works on hills depends on the vehicle speed, the load, and the steepness of the hills. When going up steep hills, pressing the accelerator pedal may be necessary to maintain vehicle speed.

While going downhill, cruise braking helps maintain driver selected speed.

Cruise Grade Braking is enabled when the vehicle is started and cruise control is active. It is not enabled in Range Selection Mode.

It assists in maintaining driver selected speed when driving on downhill grades by using the engine and transmission to slow the vehicle.

For other forms of descent control, see Hill Descent Control (HDC) 0 244, Automatic

Transmission 0 232, and Tow/Haul Mode

0 235.

Ending Cruise Control

There are four ways to end cruise control:

    Step lightly on the brake pedal.
    Press *.
    Shift the transmission to N (Neutral).
    To turn off cruise control, press 5.

Erasing Speed Memory

The cruise control set speed is erased from memory if 5 is pressed or the ignition is turned off.
