How It Works
The traction control system constantly monitors the speed of the front and rear wheels. If Model Y experiences a loss of traction, the system minimizes wheel spin by controlling brake pressure and motor power. By default, the traction control system is on. Under normal conditions, it should remain on to ensure maximum safety.
Disabling Traction Control
Under normal conditions, the traction control system should remain on. Turn it off only in circumstances where you deliberately want the wheels to spin, such as:
- Starting on a loose surface, such as gravel or snow.
- Driving in deep snow, sand or mud.
- Rocking out of a hole or deep rut.
- Driving off-road.
On Rear-Wheel Drive vehicles, turn off traction control and allow the wheels to spin by touching.
On All-Wheel Drive vehicles, you can choose one of these options, depending on the circumstances:
- Slip Start is designed to make it easier to dislodge Model Y when stuck in mud, snow, ice, etc. Turning on Slip Start allows the wheels to spin, making it possible to rock Model Y out of a situation in which the wheels are stuck.
- Off-Road Assist is designed to provide overall improvements when driving off-road. In addition to allowing the wheels to spin, Off-Road Assist balances the torque between the front and rear motors to optimize traction. Off-Road Assist improves traction on rough and soft surfaces where one side of the vehicle may lose traction while the other side still has traction. When Off-Road Assist is on, the accelerator pedal provides more gradual torque, which is useful for crawling at low speeds (for example, over rocky surfaces). When enabled, OFF-ROAD displays on the touchscreen above the driving speed.
After the circumstances that required you to turn on Slip Start or Off-Road Assist have passed, it is strongly recommended that you turn the setting off to re-enable traction control. If you leave these settings on, Traction Control automatically re-enables on your next drive.
