Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Accel Control
When the + RES SW is held down during cruise control driving, the engine control module adjusts the throttle valve to gradually accelerate the vehicle. Every time the + RES SW is tapped momentarily, the vehicle speed is accelerated by approximately 1.6 km/h. However, in the case of tap-up operation which puts a difference of more than a 5 km/h between the set speed and the actual vehicle speed, the device does not change the set speed. (Tap-up operation is not available.)
