How do you turn on traction control on a 2016 Toyota Sienna?
Press the TRAC OFF button briefly to re-enable traction control. When traction control is active, the TRAC OFF indicator on the instrument cluster should disappear. Traction control is normally on by default as part of Toyota’s Vehicle Stability Control system, and it helps manage wheel spin and stability on slippery roads.
In the 2016 Sienna, traction control (often called TCS or part of VSC) can be temporarily disabled for snow, mud, or sand, then easily reactivated. This guide explains where to find the control, how to re-enable it, what indicators to look for, and what to do if it won’t respond.
Where to Find the Traction Control Switch
The TRAC OFF switch is typically located on the lower left portion of the dashboard, near the driver's knee area, or close to the steering column. It is labeled TRAC OFF or uses an icon of a car with wavy lines. If you can’t spot it, consult the owner’s manual for the exact location on your trim level.
Steps to Re-enable Traction Control
Use this quick guide to re-activate traction control after it has been turned off.
- Start the engine and ensure the vehicle is stationary or moving at a very slow, safe speed.
- Locate the TRAC OFF button on the dash (the label or icon helps identify it).
- Press the TRAC OFF button briefly to re-enable traction control. The TRAC OFF indicator should turn off or disappear from the instrument cluster when the system is active.
- Drive normally to confirm proper operation. If the indicator remains lit or you still feel wheel spin, stop safely and check for fault indicators or consult a dealership.
Once re-enabled, the vehicle’s stability control system will periodically intervene as needed to help maintain grip. If the system cannot be reactivated after multiple attempts, there may be a fault that requires service.
Indicator Lights and What They Mean
TRAC OFF / VSC OFF lights
The TRAC OFF indicator appears on the instrument cluster when traction control is disabled. It should go dark when the system is active. If the light stays on after you press the switch, there may be a fault, a fuse issue, or a condition that requires service.
Troubleshooting Tips
If you’re unable to turn traction control back on by pressing the button, try these steps: ensure the ignition is ON, verify there are no fault warnings, check relevant fuses tied to the Vehicle Stability Control system, and consider having the system inspected at a Toyota service center if the indicator remains illuminated.
Summary
Turning on traction control in a 2016 Toyota Sienna is typically as simple as briefly pressing the TRAC OFF button to re-enable the system. The switch is usually found on the lower left side of the dashboard near the steering column. When traction control is active, the TRAC OFF light should disappear from the dash, and the system will assist with grip and stability. If you encounter persistent trouble reactivating the system or continued warning lights, consult the owner’s manual or a Toyota dealer for diagnostics.
