Understanding Toyota Traffic Jam Assist

Toyota’s Traffic Jam Assist is an innovative feature designed to take the edge off the daily grind of stop-and-go driving. It’s all about making your life easier when navigating those pesky traffic jams, especially for us living in Southern California.

Supported Roadways

To use Traffic Jam Assist, you need to be driving on a supported limited-access roadway. Think highways with divided lanes and on-and-off ramps – the kind of roads you often find yourself stuck in traffic on. It’s here that Traffic Jam Assist really shines.

Prerequisites

Before you engage Traffic Jam Assist, there are a few prerequisites to remember. First, you should have Dynamic Radar Cruise Control operating at a set speed and Lane Tracing Assist activated. Additionally, Traffic Jam Assist and the Pre-Collision System must be turned on in your vehicle’s settings. Don’t forget to enable Dynamic Radar Cruise Control’s extended Resume Time setting.

Driver Attention

While Traffic Jam Assist can make your life easier, it’s no excuse to check out mentally. Driver inattentiveness can deactivate the system, so always stay focused on the road.

DriveConnect Subscription

To utilize Traffic Jam Assist, you’ll need an active DriveConnect subscription or trial. This essential component enables this fantastic feature.

How Traffic Jam Assist Works

Once everything’s in place, Traffic Jam Assist steps in when system sensors detect traffic slowing down. The system can handle speeds within the range of 0 to 25 miles per hour. It takes control of acceleration and braking and even offers hands-free steering control – but remember, under your active supervision.

Driver Monitoring

To ensure your safety, a Driver Monitor Camera watches over you. It keeps tabs on your attentiveness, but factors like posture, height, and even face coverings (like masks or sunglasses) can affect its detection. You can disable the recording function in the settings if you prefer.

Visual Indicators

When Traffic Jam Assist is active, your multi-information display will show specific graphics indicating the vehicle-to-vehicle distance setting. This way, you’re always aware of the system’s status, even if the instrument cluster layout varies between Toyota models.

Stay Alert

Traffic Jam Assist is a great tool, but it’s not a replacement for an alert driver. If the system detects conditions no longer meet its criteria or traffic speeds exceed 25 miles per hour, it will prompt you with audible and visual alerts to take control of the vehicle.

And there you have it – a comprehensive overview of Toyota’s Traffic Jam Assist. It’s the latest addition to Toyota’s lineup of advanced driver assistance features, and it’s here to make your daily commute in stop-and-go traffic a whole lot more manageable. Stay tuned for more insights into Toyota’s active safety and driver assistance technologies on our blog.

How to Activate Toyota Traffic Jam Assist:

> 1. Select Supported Roadway: Ensure you drive on a supported limited access roadway, like a highway with divided lanes and on/off ramps. Traffic Jam Assist works best in these conditions.

> 2. Activate Dynamic Radar Cruise Control (DRCC): Make sure your Dynamic Radar Cruise Control is operating at a set speed. This is a prerequisite for Traffic Jam Assist.

> 3. Activate Lane Tracing Assist (LTA): Ensure Lane Tracing Assist is activated to help keep your vehicle centered in its lane.

> 4. Turn on Traffic Jam Assist and Pre-Collision System: In your vehicle’s settings, activate both Traffic Jam Assist and the Pre-Collision System. 

> 5. Adjust Dynamic Radar Cruise Control Setting: Within the settings, you may also want to adjust Dynamic Radar Cruise Control’s extended Resume Time setting to your preference.

> 6. Verify DriveConnect Subscription: Ensure you have an active DriveConnect subscription or trial; this is required for Traffic Jam Assist.

> 7. Drive with Caution: Drive your vehicle with Caution and stay attentive. Traffic Jam Assist is designed to assist but requires active supervision.

That’s it! Once these conditions are met, Traffic Jam Assist should activate when traffic slows down within the system’s operating range (0 to 25 miles per hour). You’ll see distinct graphics on the multi-information display, indicating that Traffic Jam Assist is active. Always be prepared to take control if conditions change or if traffic speeds exceed 25 miles per hour, as the system will prompt you with audible and visual alerts. Enjoy the convenience of Traffic Jam Assist during slow-moving stop-and-go traffic.
