Maintenance and care
■Note for a smart entry & start system
If the door handle becomes wet while the electronic key is within the effective
range, the door may lock and unlock repeatedly. In that case, follow the fol-
lowing correction procedures to wash the vehicle:
●Place the key in a position 2 m (6 ft.) or more separate from the vehicle
while the vehicle is being washed. (Take care to ensure that the key is not
stolen.)
●Set the electronic key to battery-saving mode to disable the smart entry &
start system. (P. 285)
■Wheels and wheel ornaments
●Remove any dirt immediately by using a neutral detergent.
●Wash detergent off with water immediately after use.
●To protect the paint from damage, make sure to observe the following pre-
cautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the wheels when they are hot, such as after driv-
ing or parking in hot weather
■Brake pads and calipers
Rust may form if the vehicle is parked with wet brake pads or disc rotors,
causing them to stick. Before parking the vehicle after it is washed, drive
slowly and apply the brakes several times to dry the parts.
■Bumpers
Do not scrub with abrasive cleaners.
■Front side windows water-repellent coating
The following precautions can extend the effectiveness of the water-repellent
coating.
●Remove any dirt, etc. from the front side windows regularly.
●Do not allow dirt and dust to accumulate on the windows for a long period.
Clean the windows with a soft, damp cloth as soon as possible.
●Do not use wax or glass cleaners that contain abrasives when cleaning the
windows.
●Do not use any metallic objects to remove condensation build up.
■Plated portions
If dirt cannot be removed, clean the parts as follows:
●Use a soft cloth dampened with an approximately 5% solution of neutral
detergent and water to clean the dirt off.
●Wipe the surface with a dry, soft cloth to remove any remaining moisture.
●To remove oily deposits, use alcohol wet wipes or a similar product.

Maintenance and care
■When opening the cover of the positive (+) battery terminal
■ Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, obser ve the following precautions before
recharging:
● If recharging with the 12-volt battery installed on the vehicle, be sure to dis-
connect the ground cable.
● Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the 12-volt battery.
■ After recharging/reconnecting the 12-volt battery
● Unlocking the doors using the smart entry & start system may not be possi-
ble immediately after reconnecting the 12-volt battery. If this happens, use
the wireless remote control or the mechanical key to lock/unlock the doors.
● Start the hybrid system with the power switch in ACCESSORY mode. The
hybrid system may not start with the power switch turned off. However, the
hybrid system will operate normally from the second attempt.
● The power switch mode is recorded by the vehicle. If the 12-volt battery is
reconnected, the vehicle will return the power switch mode to the status it
was in before the 12-volt battery was disconnected. Make sure to turn off
the power switch before disconnect the 12-volt battery. Take extra care
when connecting the 12-volt battery if the power switch mode prior to dis-
charge is unknown.
If the system will not start even after multiple attempts at all methods above,
contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer.
While pushing the portion shown in the
illustration from both sides, lift the end of
the cover up.
