Before recharging
When recharging, the battery produces hydrogen gas which is flammable
and explosive. Therefore, before recharging:
●If recharging with the battery installed on the vehicle, be sure to discon-
nect the ground cable.
● Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the battery.
■ After recharging/reconnecting the batt ery (vehicles with a smart entry
& start system)
● Unlocking the doors using the smart entry & start system may not be
possible immediately after reconnecti ng the battery. If this happens, use
the wireless remote control or the mechanical key to lock/unlock the
doors.
● Start the engine with the “ENGINE START STOP” switch in ACCES-
SORY mode. The engine may not start with the “ENGINE START STOP”
switch turned off. However, the engine will operate normally from the sec-
ond attempt.
● The “ENGINE START STOP” switch mode is recorded by the vehicle. If
the battery is reconnected, the vehicle will return the “ENGINE START
STOP” switch mode to the status it was in before the battery was discon-
nected. Make sure to turn off the engine before disconnect the battery.
Take extra care when connecting the battery if the “ENGINE START
STOP” switch mode prior to discharge is unknown.
If the engine will not start even after multiple attempts, contact any
authorized Toyota dealer or repairer, or another duly qualified and equipped
professional.

down your vehicle, the angles
shaded in black must be 45°.
Do not overly tighten the tie
downs or the vehicle may be
damaged.
NOTICE
■ To prevent causing serious damage to the transmission when towing
using a wheel-lift type truck (vehicles with an automatic transmission)
Never tow this vehicle from the front with the rear wheels on the ground.
■ To prevent damaging the vehicle
●Vehicles without a smart entry & start system: Do not tow the vehicle from
the rear when the engine switch is in the “LOCK” position or the key is
removed. The steering lock mechanism is not strong enough to hold the
front wheels straight.
● Vehicles with a smart entry & start system: Do not tow the vehicle from the
rear when the “ENGINE START STOP” switch is off. The steering lock
mechanism is not strong enough to hold the front wheels straight.
● When raising the vehicle from the rear, 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 from the rear.
