Understanding AWD in the Toyota Highlander 2019
Before diving into how to turn on AWD in your 2019 Highlander, it’s important to understand how the system works. The 2019 Toyota Highlander AWD system is known as Dynamic Torque Control AWD, and it’s designed to improve traction and stability by automatically sending power to the wheels that need it most.
How Toyota’s Dynamic Torque Control AWD Works
Unlike traditional AWD systems that operate all four wheels all the time, Dynamic Torque Control AWD in the 2019 Highlander is more energy-efficient. At normal driving conditions (dry roads), the system operates in front-wheel drive (FWD) mode. This reduces mechanical drag and improves fuel economy. However, when the system detects wheel slip or a loss of traction, it automatically engages the rear wheels as needed.
The engagement is seamless and automatic, managed by sensors that monitor wheel speed, throttle position, steering angle, and other relevant inputs.
Which 2019 Toyota Highlander Trims Offer AWD?
Not all trim levels of the 2019 Toyota Highlander come with AWD. The AWD feature was available on the following trim levels:
- LE
- XLE
- Hybrid XLE
- Hybrid Limited
So, if you’re not sure whether your 2019 Highlander has AWD, the easiest way to confirm is by checking your vehicle’s VIN (Vehicle Identification Number) or consulting your owner’s manual. You can also check your gear shifter; a “4WD” or “AWD” switch near the shifter is a strong indicator that your Highlander has the system.
Steps to Turn On AWD on a Toyota Highlander 2019
Many drivers assume they need to manually toggle a switch or button to “turn on” AWD. However, in the 2019 Toyota Highlander with Dynamic Torque Control AWD, the system usually operates automatically. But under certain conditions, users can activate or lock AWD mode manually. Here’s how to properly turn on AWD when you need to.
Step 1: Verify That Your Vehicle Is Parked
To engage AWD functions manually, your vehicle must be entirely stopped and in “P” (Park) mode. This is a built-in safety feature to prevent accidental shifting while the vehicle is in motion.
Step 2: Locate the AWD Switch
The AWD control switch is typically found near the gear shift lever. It may be labeled with options like “Auto,” “4WD,” or “Locked.” Some models also have a “Mud & Sand,” “Rock & Dirt,” or “Snow” specific mode that you can toggle.
Step 3: Toggle to AWD Mode
If you’re preparing to drive in less-than-ideal road conditions, such as snow, rain, or off-road terrain, follow these steps:
- Bring the gear shifter to “P” and ensure the vehicle is at a complete stop.
- Press or toggle the AWD switch to “4WD” or the more specific terrain mode (e.g., “Mud & Sand”, “Snow”).
- You’ll hear a chime or see an indicator light on your dashboard that confirms AWD is engaged.
Step 4: Return to Auto Mode When Conditions Improve
If you’ve manually locked the AWD, it’s important to return the system to “Auto” mode when driving conditions improve. Operating in locked AWD on paved, dry roads for an extended time can decrease fuel efficiency and increase mechanical wear.
