Toyota bZ4X Owner's Manual: Maintenance

Maintenance Requirements for a Safe and Economical Driving Experience

To ensure safe and economical driving, day-to-day care and regular maintenance are essential. It is the owner’s responsibility to perform periodic checks and address any issues early. Regular maintenance not only prolongs the life of your vehicle but also helps avoid unexpected breakdowns and costly repairs. Following the recommended service intervals and using the proper maintenance procedures ensures that every system on your vehicle functions as it should.

Toyota recommends a structured maintenance plan to keep your vehicle in prime condition. Daily care, swept in with routine inspections, and scheduled maintenance tasks are crucial components of a balanced maintenance strategy.

Repair and Replacement Guidelines

When repairs or replacements are necessary, it is highly recommended that you use genuine Toyota parts. Genuine parts are specifically designed to match the performance and quality standards of your vehicle, ensuring that every system operates correctly. If non-Toyota parts are used in replacement, or if repairs are handled by a shop other than an authorized Toyota dealer, it is important to confirm that your warranty coverage remains intact. This protects you from potential issues that could affect the vehicle's performance and your overall safety.

Allowing inspection and repairs to be performed by a Toyota dealer is highly recommended. Toyota technicians are well-trained specialists who remain up to date with the latest service information and innovations. Their expertise covers every system in your vehicle, ensuring that repairs and maintenance are completed correctly. Moreover, maintaining a record of repair orders is crucial, as this documentation provides proof that the required maintenance has been properly performed under warranty coverage. In the event of any issues while your vehicle is still under warranty, an authorized Toyota dealer will be able to promptly address and take care of the problem.

WARNING – The Critical Importance of Proper Maintenance

If Your Vehicle is Not Properly Maintained

Improper maintenance may result in serious damage to the vehicle and can potentially lead to death or severe injury. Neglecting regular inspections and timely repairs can compromise both the mechanical integrity and safety features designed to protect you in critical moments.

Handling of the 12-Volt Battery

• Oils and fluids contained in the vehicle-as well as waste products generated from component wear-can emit chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. Avoid any unnecessary exposure and immediately wash any affected area.
• The 12-volt battery posts, terminals, and related accessories contain lead and lead compounds, which are known to cause brain damage. Always wash your hands after handling these components.

General Maintenance

General maintenance should be performed daily or as frequently needed to keep every aspect of your vehicle in optimal condition. Simple tasks such as checking fluid levels, inspecting tires, and ensuring that all lights and electrical systems operate properly can be done by yourself or during a routine service by a Toyota dealer. Daily care is the first defense against wear and tear and helps keep your vehicle running smoothly.

Scheduled Maintenance

Scheduled maintenance is designed to address specific components at predetermined intervals. Following the maintenance schedule outlined in your “Scheduled Maintenance Guide” or “Owner’s Manual Supplement” is critical to preserving performance and safety. These scheduled maintenance tasks may include oil changes, filter replacements, brake inspections, and more. Adhering to these guidelines minimizes the risk of unexpected breakdowns and prolongs the lifespan of critical systems.

In summary, a rigorous maintenance program is the cornerstone of safe and efficient vehicle operation. By utilizing genuine parts, entrusting repairs to qualified Toyota technicians, and conducting daily as well as scheduled maintenance, you safeguard both your investment and your safety on the road. Regular upkeep not only optimizes vehicle performance but also supports the reliability of advanced safety systems, ensuring that your driving experience is secure and stress-free.
