Automatic Traction Control

Electric vehicles with ABS are equipped with automatic traction control (ATC). On these vehicles, the ATC system automatically limits wheel spin during reduced-traction situations. If the vehicle comes to a stop in soft soil or sand, it may be necessary to back up prior to attempting forward movement.

When the ATC system is in normal mode, it applies gentle braking to the spinning wheel to feed power to the wheel(s) with better traction. If both wheels are spinning, the system signals the motor to reduce power.

If the system detects wheel spin, the wheel spin telltale, shown in Fig. flashes and an alert is shown on the driver display.

Pressing the ATC SPIN switch, shown in Fig. deactivates ATC and allows drive wheel spin. When ATC is off, an ATC deactivated telltale, as shown in Fig. appears on the driver display. Pressing the switch again, or cycling the keyswitch, cycles the system back to normal operation.
