1. What is Remote Start and Why Use It on Your 2021 Toyota Highlander?
Remote start is a feature that allows you to start your 2021 Toyota Highlander from a distance, typically using your key fob or a smartphone app. It is a convenience feature that allows you to pre-condition your vehicle’s interior before you even get in and provides added comfort and security.
What are the benefits of remote start?
- Comfort: Preheat your vehicle in the winter or cool it down in the summer before you get inside.
- Convenience: Start your vehicle from inside your home, office, or anywhere within range.
- Security: Ensure your vehicle is ready to go the moment you step inside.
- Time-saving: Defrost windows or warm up the engine, saving you valuable time in the morning.
2. How Does the Remote Start System Work in the 2021 Toyota Highlander?
The remote start system in the 2021 Toyota Highlander uses the key fob or Toyota app to send a signal to the vehicle’s computer, initiating the engine start while keeping the doors locked and the security system active. This system relies on a combination of hardware and software designed to ensure a secure and reliable start every time.
Key components of the remote start system
| Component | Description |
|---|---|
| Key Fob | The key fob transmits a radio frequency signal to the vehicle. Pressing the start button on the fob initiates the remote start sequence, provided the vehicle is within range and certain conditions are met (e.g., all doors are closed and locked). |
| Toyota App | The Toyota app (available on compatible smartphones) allows remote start functionality from virtually anywhere with cellular service. The app communicates with Toyota’s servers, which then relay the start command to the vehicle. |
| Vehicle Computer | The vehicle’s computer (ECU or ECM) receives the remote start signal, verifies its authenticity, and then initiates the engine start sequence. It also monitors various safety parameters, such as door status and brake pedal position, before allowing the engine to start. |
| Security System | The security system remains active during remote start to prevent unauthorized access. The doors stay locked, and the immobilizer prevents the vehicle from being driven without the key present inside the cabin. |
3. Step-by-Step Guide: Using the Key Fob for Remote Start on Your 2021 Toyota Highlander
To use the remote start feature on your 2021 Toyota Highlander with the key fob, follow these simple steps for a seamless start.
- Ensure the vehicle is in park (P) and all doors are closed and locked. Make sure all doors, hood, and tailgate are securely closed.
- Press the lock button on the key fob. This ensures the vehicle is locked and ready to receive the remote start command.
- Immediately press and hold the remote start button (usually a circular arrow) for about 3 seconds. The vehicle’s turn signal lights will flash to indicate that the remote start sequence has been initiated.
- The engine will start and run for 10 minutes. If you wish to extend the run time, you can repeat steps 2 and 3 while the engine is running. The engine can be remotely started for a maximum of 20 minutes (two 10-minute intervals).
