How do you turn off daytime running lights on a Toyota Highlander?

In most Toyota Highlander models, there isn’t a simple, permanent switch to disable daytime running lights (DRLs) for everyday driving. If a DRL-off option exists, it’s model-year and trim dependent and may require dealer programming. This article explains what you can do as a owner and what may require professional help.

What DRLs do in the Highlander and why they matter

Daytime running lights are designed to keep the vehicle visible during daylight hours. On many Highlander models, DRLs come on automatically when the engine is running and the headlights are off. For safety and regulatory reasons, some markets require DRLs to remain on, which means there are limited owner controls to disable them. Understanding your specific year and trim is key, as the availability of a DRL-off option varies widely.

Model-year and trim variations you should know

The ability to disable DRLs varies by generation, region, and equipment package. Some early and recent Highlanders offer no user-accessible switch to turn DRLs off, while a few trims or markets may provide a toggle or setting in the vehicle’s menu. Always consult your owner’s manual for model-specific instructions, and note that even when a setting exists, certain driving modes or conditions may keep DRLs active.

Owner controls you can try (if your model supports them)

Before attempting any changes, it’s important to understand that results depend on your exact year and trim. If your Highlander has any of these options, you can try them in this order:

1. Check the headlight switch: Some Highlanders place DRL control in the same stalk or dial used for exterior lights. If the switch offers Off or Parking Lights positions, try selecting those to see if DRLs disable. Note that on many models DRLs stay active even in these positions.


2. Inspect the vehicle settings menu: Some models provide a DRL toggle in Settings > Vehicle > Lighting. If a DRL Off option exists, enable it and verify whether DRLs switch off.


3. Test with the engine running and lights off: After selecting Off or Parking Lights (if available), observe whether DRLs remain on. If they do, the DRL function may be locked to the factory setting and not user-adjustable.


4. Be mindful of local regulations: In many regions DRLs are required by law, and disabling them could be illegal or affect insurance/warranty coverage.

In practice, many Highlander owners will find that DRLs cannot be turned off through normal consumer controls. If you don’t see a DRL-off option in your switch or settings, you should assume DRLs are not user-adjustable on your vehicle.

What to do if you cannot disable DRLs with consumer controls

If your model does not present a DRL-off option in the switch or settings menu, and you still need DRLs disabled for a specific situation, you have a few avenues to consider. Each comes with caveats about safety, legality, and warranty.

1. Consult a Toyota dealer or authorized service center: Some regions allow dealer-enabled coding or programming to alter DRL behavior. This varies by market and may require documentation or compliance with local laws.


2. Do not attempt DIY electrical modifications: Unauthorized wiring changes or aftermarket modules that claim to disable DRLs can interfere with safety systems and may void warranty.


3. Check local regulations and insurance policies: Ensure that turning DRLs off complies with local traffic laws and won’t affect your coverage in the event of an incident.


4. Ask about approved alternatives: In some cases, dealerships can offer sanctioned options that reduce glare or adjust lighting behavior without fully disabling DRLs.

Because DRLs are tied to safety and regulatory standards, any change should be undertaken with professional guidance and a clear understanding of the legal implications for your location and vehicle warranty.

Summary and takeaway

Daytime running lights on a Toyota Highlander are designed to enhance daytime visibility and, in many cases, cannot be turned off by the owner. If a DRL-off option exists, it is model-year and region specific and may require dealer programming. For most drivers, the recommended approach is to consult the owner’s manual, check the Settings menu for any available DRL toggle, and contact an authorized Toyota service center before pursuing any modification. Always weigh safety, legality, and warranty considerations when considering disabling DRLs.

Additional notes for readers

If you’re researching this topic due to glare or a medical cause, explain your situation to a Toyota technician. They can confirm whether there is an official, compliant path to modify DRL behavior on your exact Highlander, and they can guide you through any approved steps or alternatives.

Can you disable daytime running lights?

Yes, you can turn off daytime running lights, but the method depends on your car. A common method is to engage the parking brake and turn the headlight switch to the "off" position while parked. For some newer cars, you can permanently disable them through the vehicle's infotainment or settings menu, while others may require more complex workarounds like removing a fuse or a more technical modification, such as using a special software for programming.

• Engage the parking brake: Make sure the car is in park. Activate the parking brake (either the manual lever or the electric button) and turn the headlights to the "off" position.
• Restart the car: Turn the car off and then back on again. The DRLs should remain off as long as the parking brake is engaged.
• Important: The DRLs will turn back on automatically once you disengage the parking brake. 

Permanent or menu-based turn-off

• Check the vehicle settings: Many modern cars allow you to disable DRLs in the infotainment system. Look for a "Vehicle Settings," "Customize," or "Light Settings" menu. 
• Use a programming tool: Some manufacturers require specific software and a tool (like an OBDLink adapter) to make modifications to the vehicle's settings. 
• Consult the owner's manual: The most accurate instructions for your specific vehicle will be in the owner's manual.

Other methods

• Remove the fuse: Some vehicles have a specific fuse for the DRLs, which can be removed. However, this could have unintended consequences, so it is important to know exactly which fuse you are removing.
• Contact a dealership: If you are not comfortable with any of these methods, a dealership or a qualified mechanic can disable the DRLs for you.
