■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following before recharging:
● If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
● Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the battery.
■ After recharging/reconnecting the battery (vehicles with smart entry &
start system)
The engine may not start. Follow the procedure below to initialize the system.
Shift the shift lever to P (automat ic transmission) or depress the brake
pedal with the shift lever in N (manual transmission).
Open and close any of the doors.
Restart the engine.
● Unlocking the doors using the smart entry & start system may not be possi-
ble immediately after reconnecting the battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the doors.
● Start the engine with the engine switch in ACCESSORY mode. The engine
may not start with the engine switch turned off. However, the engine will
operate normally from the second attempt.
● The engine switch mode is recorded by the vehicle. If the battery is recon-
nected, the vehicle will return the engine switch mode to the status it was in
before the battery was disconnected. Make sure to turn off the engine
before disconnect the battery. Take extra care when connecting the battery
if the engine switch mode prior to discharge is unknown.
If the system will not start even after multiple attempts, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■ If a symbol of a battery is shown on the multi-information display (if
equipped)
There is a malfunction in the vehicle’s charging system.
Immediately stop the vehicle in a safe place and contact any authorized
Toyota retailer or Toyota authorized repai rer, or any reliable repairer. Continu-
ing to drive the vehicle may be dangerous.

NOTICE
■To prevent damage to the vehicle when towing using a wheel-lift type
truck
● Do not tow the vehicle from the rear when the engine switch is in the
“LOCK” position or the key is removed (vehicles without smart entry & start
system) or the engine switch is turned to off (vehicles with smart entry &
start system). The steering lock mechanism is not strong enough to hold
the front wheels straight.
● When raising the vehicle, ensure adequate ground clearance for towing at
the opposite end of the raised vehicle. Without adequate clearance, the
vehicle could be damaged while being towed.
■ To prevent damage to the vehicle when towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
■ To prevent damage to the vehicle during emergency towing
Do not secure cables or chains to the suspension components.
■ When towing a vehicle equipped with the Stop & Start system (if
equipped)
When it is necessary to tow the vehicle with all four wheels contacting the
ground, perform the following procedure before towing the vehicle to protect
the system.
Turn the engine switch to the “LOCK” position (vehicles without smart entry
& start system) or off (vehicles with smart entry & start system) once, and
then start the engine. If the engine does not start, turn the engine switch to
the “ON” position (vehicles without smart entry & start system) or IGNITION
ON mode (vehicles with smart entry & start system).
