Second generation VI (2009–2024) / Hyundai Equus VI 2009-2024 Service Manual / Engine Electrical System / Cruise Control System / Description and Operation
| Cruise Control |
The cruise control system is engaged by the cruise "ON/OFF"
main switch located on right of steering wheel column. The system has
the capability to cruise, coast, accelerate and resume speed.
It also has a safety interrupt, engaged upon depressing brake or shifting select lever.
The ECM is the control module for this system. The main
components of cruise control system are mode control switches,
transmission range switch, brake switch, vehicle speed sensor, ECM and
ETS motor that connect throttle body.
The ECM contains a low speed limit which will prevent system engagement below a minimum speed of 40km/h (25mph).
The operation of the controller is controlled by mode control switches located on steering wheel.
Transmission range switch and brake switch are provided to
disengage the cruise control system. The switches are on brake pedal
bracket and transmission. When the brake pedal is depressed or select
lever shifted, the cruise control system is electrically disengaged and
the throttle is returned to the idle position.
| Cruise main switch (CRUISE) |
The cruise control system is engaged by pressing the cruise
"ON/OFF" main switch. Pressing the cruise "ON/OFF" main switch again
releases throttle, clears cruise memory speed, and puts vehicle in a
non-cruise mode.
| Set/Coast switch (SET/–) |
The "SET/–" switch located on right of steering wheel column has two functions.
The set function - Push the "SET/–" switch and release it
at the desired speed. The SET indicator light in the instrument cluster
will illuminate. Release the accelerator pedal. The desired speed will
automatically be maintained.
The coast function - Push the "SET/–" switch and hold it
when the cruise control is on. The vehicle will gradually slow down.
Release the switch at the desired speed. The desired speed will be
maintained.
Push the "SET/–" switch and release it quickly. The cruising speed will decrease by 2km/h or 1mph.
| Resume/Accel switch (RES/+) |
The "RES/+" switch located on right of steering wheel column has two functions.
The resume function - If any method other than the cruise
“ON/OFF” main switch was used to cancel cruising speed temporarily
and the system is still activated, the most recent set speed will
automatically resume when the "RES/+" switch is pushed. It will not
resume, however, if the vehicle speed has dropped below approximately
40km/h (25mph).
The accel function - Push the "RES/+" switch and hold it when
the cruise control is on. The vehicle will gradually accelerate.
Release the switch at the desired speed. The desired speed will be
maintained.
Push the "RES/+" switch and release it quickly. The cruising speed will increase by 2km/h or 1mph.
| Cancel switch (CANCEL) |
The cruise control system is temporarily disengaged by pushing the "CANCEL" switch.
Cruise speed canceled by this switch can be recovered by pushing the "RES/+" switch.
