Chevrolet Sonic Owner's Manual: Cruise Control
If the vehicle is 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 40 km/h (25 mph).
Warning
Cruise control can be dangerous where you cannot drive safely at a steady speed. Do not use the 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.
If the vehicle's Traction Control System (TCS) or StabiliTrak system begins to limit wheel spin while using cruise control, the cruise control will automatically disengage. See Traction Control/Electronic Stability Control. If a collision alert occurs when cruise control is activated, cruise control is disengaged. See Forward Collision Alert (FCA) System. When road conditions allow you to safely use it again, the cruise control can be turned back on.
If the brakes are applied, the cruise control shuts off.
(On/Off): Press to turn the cruise
control system on and off.
RES/+ (Resume/Accelerate): Move the thumbwheel up briefly to make the vehicle resume to a previously set speed or hold upwards to accelerate. If cruise control is already active, use to increase vehicle speed.
SET/− (Set/Coast): Move the thumbwheel down briefly to set the speed and activate cruise control. If cruise control is already active, use to decrease speed.
(Cancel): Press to disengage cruise
control without erasing the set speed from memory.
Setting Cruise Control
If is on when not in use, it could
get bumped and go into cruise when not desired. Keep o off when cruise control is
not being used.
To set cruise control:
1. Press the button to turn the
cruise system on.
2. Get to the speed desired.
3. Move the thumbwheel down to SET/- and release it.
4. Take your foot off the accelerator pedal.
Resuming a Set Speed
If the cruise control is set at a desired speed and then the brakes or clutch for manual transmissions are applied, the cruise control is disengaged without erasing the set speed from memory.
Once the vehicle reaches about 40 km/h (25 mph) or more, move the thumbwheel up toward RES/+ briefly. The vehicle returns to the previous set speed.
Increasing Speed While Using Cruise Control
If the cruise control system is already activated:
- Move the thumbwheel up toward RES/+ and hold it until the desired speed is reached, then release it.
- To increase the vehicle speed in small increments, move the thumbwheel up toward RES/+ briefly and then release it. For each press, the vehicle goes about 1.6 km/h (1 mph) faster.
Reducing Speed While Using Cruise Control
If the cruise control system is already activated:
- Move the thumbwheel toward SET/− and hold until the desired lower speed is reached, then release it.
- To decrease the vehicle speed in smaller increments, move the thumbwheel toward SET/− briefly. For each press, the vehicle goes about 1.6 km/h (1 mph) slower.
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 slows down to the previous set cruise control speed. While pressing the accelerator pedal or shortly following the release to override cruise control, briefly moving the thumbwheel toward SET– will result in cruise control set to the current vehicle speed.
Using Cruise Control on Hills
How well cruise control works on hills depends on the vehicle speed, load, and the steepness of the hills. When going up steep hills, you might have to step on the accelerator pedal to maintain the vehicle speed. When going downhill, you might have to brake or shift to a lower gear to maintain the vehicle speed. When the brakes are applied, cruise control will turn off.
Ending Cruise Control
There are three ways to end cruise control:
- To disengage cruise control, step lightly on the brake pedal or clutch for manual transmission.
- Press on the steering wheel.
- To turn off cruise control, press
on the steering wheel.
Erasing Speed Memory
The cruise control set speed is erased from memory if the o button is pressed or if the ignition is turned off.
