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.

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.

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.

tions, conduct research and development, and improve quality.

• 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
