For your infor mation
Please note that this manual applies to all models and explains all equipment,
including 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.
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.
A wide variety of non-genuine spare parts and accessories for Toyota vehi-
cles are currently available in 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. Modi-
fication with non-genuine Toyota products could affect its performance, safety
or durability, and may even violate governmental regulations. In addition,

covered under warranty.
