Toyota bZ4X Owner's Manual: Using the Remote Air Conditioning System

The Remote Air Conditioning System in your 2025 Toyota bZ4X offers the convenience of cooling or pre-heating the vehicle's interior before you even get in. This system utilizes the electrical energy stored in the high-voltage traction battery, allowing you to operate the air conditioning remotely.

If you activate the Remote Air Conditioning System while your 2025 Toyota bZ4X is connected to a charging cable, the system will prioritize drawing power from the external source. This intelligent feature helps to minimize the reduction of charge in your vehicle's traction battery, ensuring that the electricity used for pre-conditioning comes from the grid.

Rest assured that after you stop using the Remote Air Conditioning System, the vehicle will automatically resume its charging process if it is still connected to an external power source, ensuring your battery is ready for your next drive.

Important Step Before Exiting Your Vehicle

Before you leave your 2025 Toyota bZ4X, take a moment to check the temperature setting of the air conditioning system. The Remote Air Conditioning System will operate based on the last temperature settings you had selected when you turned off the vehicle.

Activating the Remote Air Conditioning System

To activate the Remote Air Conditioning System in your 2025 Toyota bZ4X, press and hold the "A/C" button on your vehicle's wireless remote control for a few seconds. This will initiate the system and start cooling or heating the interior.

For safety and security reasons, the Remote Air Conditioning System will automatically shut off if any of the vehicle's doors are opened. If you need to stop the system before it automatically shuts off, you can do so by pressing the "A/C" button on the remote control twice in quick succession.

• Type B

Operating conditions

The system will only operate if all of the following conditions are met:

• The power switch is OFF.
• All doors are closed.
• The hood is closed.

Automatic Shut-Off of the Remote Air Conditioning System

For safety and energy conservation, the Remote Air Conditioning System in your 2025 Toyota bZ4X is programmed to automatically shut off under the following conditions:

• If approximately 20 minutes have passed since the system was initially activated.
• If any of the required operating conditions for the system are no longer being met.

The system might also automatically stop if the charge level of the high-voltage traction battery drops to a critically low level to preserve driving range.

Conditions That May Affect System Operation

The Remote Air Conditioning System in your Toyota bZ4X might not start or operate effectively in the following situations:

• If the charge level of the high-voltage traction battery is too low to support the system's operation.
• When the EV system is very cold, such as after the vehicle has been left for an extended period in freezing temperatures. In such cases, the system might prioritize warming the core EV components before fully engaging remote climate control.

Limitations of Windshield Defogging with Remote AC

When using the Remote Air Conditioning System primarily for windshield defogging in your 2025 Toyota bZ4X, you might find that the defogging effect is less potent compared to when the air conditioning system is operating normally while the vehicle is running. This is because the power available to the system might be more restricted during remote operation. Additionally, depending on the outside temperature, humidity levels, and the set temperature of the air conditioning, the outer surface of the windshield might still experience some fogging.

Security Feature During Remote Operation

As a security measure, any doors that were left unlocked on your 2025 Toyota bZ4X will be automatically locked when the Remote Air Conditioning System is activated. The emergency hazard lights will briefly flash to visually indicate that the doors have been locked.

Conditions Affecting Operation While the System is Running

During Active Use of the Remote Air Conditioning System:

• Depending on the specific operating conditions of the Remote Air Conditioning System, you might hear the electric cooling fan running, and a general operating noise might be noticeable. Please be aware that these sounds are a normal part of the system's function and do not indicate any mechanical or electrical malfunction.
• The Remote Air Conditioning System might temporarily pause or stop operating if other electrical features in your vehicle are activated or drawing significant power (for example, if the seat heaters, interior lights, or windshield wipers are turned on) or if the charge level of the 12-volt auxiliary battery becomes low. The system will typically resume operation once the electrical load decreases or the 12-volt battery recovers.
• While the Remote Air Conditioning System is running, other vehicle components such as the headlights, windshield wipers, and the instrument panel meter will not be operational. The system focuses solely on managing the interior climate.

Electronic Key Battery Depletion

Ensure that the battery in your electronic key fob is adequately charged for reliable remote operation.

When the Electronic Key Battery is Fully Depleted

If your electronic key's battery is completely dead, you will need to replace it before you can use the remote air conditioning function.

WARNING - Important Precautions for Using the Remote Air Conditioning System

• Never use the Remote Air Conditioning System if there are people, especially children or pets, inside the vehicle. Even while the system is operating, the internal temperature might still reach dangerously high or low levels due to factors such as the automatic shut-off feature. Leaving individuals or animals inside the vehicle could lead to severe heatstroke, dehydration, hypothermia, or even death or serious injury.
• Be mindful of your surroundings when using the wireless remote to activate the system. Depending on the environmental conditions, the signals from the remote might travel further than you expect. Always pay attention to the vehicle and its vicinity, and only use the switch when it is safe and necessary.
• Do not operate the Remote Air Conditioning System if the hood of your 2025 Toyota bZ4X is open. The system could unintentionally start running, and objects might be drawn into the electric cooling fan, potentially causing damage or injury.

NOTICE - Preventing Traction Battery Discharge

To avoid excessive discharge of your vehicle's high-voltage traction battery due to unintentional or prolonged use of the Remote Air Conditioning System, it is recommended to only activate the "A/C" function remotely when it is truly needed.
