For your information
Main Owner’s Manual
Please note that this manual applies to all models and all equipment, includ-
ing options. Therefore, you may find some explanations for equipment not
installed on your vehicle.
All specifications provided in this manual are current at the time of printing.
However, because of the Toyota policy of continual product improvement, we
reserve the right to make changes at any time without notice.
Depending on specifications, the vehicle shown in the illustrations may differ
from your vehicle in terms of equipment.
Noise from under vehicle after turning off the engine
Approximately five hours after the engine is turned off, you may hear sound
coming from under the vehicle for several minutes. This is the sound of a fuel
evaporation leakage check and, it does not indicate a malfunction.
Accessories, spare parts and modification of your Toyota
A wide variety of non-genuine spare parts and accessories for Toyota
vehicles are currently available on the market. You should know that Toyota
does not warrant these products and is not responsible for their
performance, repair, or replacement, or for any damage they may cause to,
or adverse effect they may have on, your Toyota vehicle.
This vehicle should not be modified with non-genuine Toyota products.
Modification with non-genuine Toyota products could affect its performance,
safety or durability, and may even violate governmental regulations. In
addition, damage or performance problems resulting from the modification
may not be covered under warranty.

Vehicle control and operation data recording
Your Toyota is equipped with sophisticated computers that record certain
information about your vehicle’s operation, such as:
• Engine speed
• Accelerator status
• Brake status
• Vehicle speed
• Shift position
The data recorded varies according to the grade level and options the vehi-
cle is equipped with. The computers do not record conversations, sound or
pictures.
●Data usage
Toyota may use the data recorded in these computers to diagnose malfunc-
tions, conduct research and development, and improve quality.
Toyota will not disclose the recorded data to a third party except:
• With the consent of the vehicle owner or with the consent of the lessee if the vehicle is leased
• In response to an official request by the police, a court of law or a govern- ment agency
• For research purposes where the data is not tied to a specific vehicle or vehicle owner
● Usage of date collected through Safety Connect (U.S. mainland only)
If your Toyota has Safety Connect and if you have subscribed to those ser-
vices, please refer to the Safety Connect Telematics Subscription Service
Agreement for information on data collected and its usage.

Event data recorder
Your vehicle has computers that monitor and control certain aspects of your
vehicle. These computers assist in driving and maintaining optimal vehicle
performance.
Besides storing data useful for troubleshooting, there is an event data
recorder (EDR) that records data in a crash or near crash event.
The SRS airbag sensor assembly contains the EDR. In a crash or near crash
event, this device may record the following information:
• Engine speed
• Whether the brake pedal was depressed or not
• Vehicle speed
• To what extent the accelerator pedal was depressed
• The transaxle shift position
• Whether the driver and front passenger wore seat belts or not
• Driver’s seat position
• SRS airbag deployment data
• SRS airbag system diagnostic data
• Front passenger’s occupant classification
The information above is intended to be used for the purpose of improving
vehicle safety performance. Unlike general data recorders, the EDR does
not record sound data such as conversation between passengers.
