2021 Toyota 4Runner Windshield Replacement: Off-Road Durability Meets ADAS Precision
The 4Runner Challenge: Flat Glass, Lift Kits, and TSS Compliance
The 2021 Toyota 4Runner is an icon of reliability and off-road capability. Its distinctive, near-vertical windshield design makes it a magnet for debris, resulting in high chip and crack rates. However, with the inclusion of Toyota Safety Sense P (TSS-P) as standard, replacing that tough glass has become a high-tech necessity, not just a simple mechanical swap.
At High-Tech Auto Glass, we understand the 4Runner community: its durability, its tendency toward customization (lift kits), and its reliance on safety. We don’t just replace the glass; we restore your vehicle to full Toyota safety compliance, ready for both the highway and the trail.
Calibration is Mandatory: Protecting Your Toyota Safety System
TSS-P and the Multipurpose Camera
The forward-facing camera, the key component of the TSS-P system (which controls Pre-Collision System and Lane Departure Alert), is meticulously mounted to the windshield. Toyota officially mandates that the camera must be recalibrated any time the glass is replaced.
Skipping calibration risks complete system malfunction:
Highway Hazards: A misaligned camera may misjudge the distance to the vehicle ahead or react unexpectedly to road signs and overpasses, creating a severe safety hazard during highway driving.
Warranty Integrity: Toyota requires correct calibration to ensure the validity of your TSS-P system warranty.
Specialized Service for Lifted 4Runners
For many 4Runner owners, stock height is just a suggestion. If your 2021 model has an aftermarket lift, the calibration process becomes unique and critical.
Angle Adjustment: A lift kit or aftermarket suspension changes the vehicle’s geometry, altering the camera’s angle relative to the ground. Our technicians are trained to identify these modifications and use the necessary Static Calibration targets and diagnostic tools to adjust the camera’s aiming point, guaranteeing accuracy from the truck’s new ride height.
OEM-Grade Assurance: We only use OEM-specification glass that guarantees perfect optical clarity, preventing the distortion that can cause calibration failure with the sensitive TSS camera.
Our High-Tech 4Runner Replacement Guarantee
We ensure your replacement is handled with the precision required for modern ADAS systems, combined with the structural strength your rugged vehicle demands.
Glass Integrity: Professional removal of the damaged glass and expert preparation of the frame, ensuring a strong, leak-proof urethane seal.
Certified Calibration: We perform the mandatory Static Calibration procedure using manufacturer-approved tools and targets, certifying that your Forward-Facing Camera is aimed with pixel-perfect accuracy.

Don’t let a cracked windshield sideline your safety. Trust the high-tech experts who know the 4Runner from the glass up.
Replacing the windshield on a 2021 Toyota 4Runner is a task best handled by a professional auto glass technician or an auto glass shop. Here’s an overview of the process:
Assessment: The technician will assess the condition of the existing windshield to determine whether it can be repaired or if a full replacement is necessary.
Gather Supplies: The necessary supplies are gathered, including the replacement windshield, automotive-grade sealant, and any additional materials or parts needed.
Safety Precautions: Safety measures are taken, such as wearing safety glasses, gloves, and other personal protective equipment.
Removal of Old Windshield:
- The old windshield is carefully removed using specialized tools designed to cut through the sealant holding it in place.
- Care is taken to avoid any damage to the vehicle’s frame, paint, or interior during the removal process.
Cleaning and Preparation:
- The area where the new windshield will be installed is thoroughly cleaned to ensure a proper seal.
- Any rust, corrosion, or contaminants are addressed to ensure a smooth and secure fit.
Installation of New Windshield:
- The new windshield is positioned and adhered in place using suitable automotive-grade sealant. This sealant creates a waterproof and airtight bond.
- Excess sealant is typically removed, and the installation is inspected to ensure it’s flush and secure.
Curing Time:
- The sealant requires time to cure and set properly. The curing time can vary depending on the type of sealant used.
Clean-Up and Inspection:
- The technician should inspect the work to ensure there are no issues with the seal, alignment, or any damage to the vehicle’s exterior or interior.
Testing:
- The new windshield is tested to ensure it is properly sealed, and there are no leaks or issues with visibility.
Interior Cleaning: Any debris or dirt that entered the vehicle during the replacement is cleaned from the interior.
Selecting a reputable auto glass service or technician with experience working on Toyota 4Runner models, specifically the 2021 model, is crucial. They can also provide guidance on any specific features or technologies integrated into the windshield, such as sensors for advanced driver assistance systems (ADAS). These sensors may need calibration or reprogramming after the windshield replacement to ensure they function correctly. Proper installation is essential for your safety and the structural integrity of your Toyota 4Runner.
