■After recharging/reconnecting the battery (vehicles with smart key sys-
tem)
● Unlocking the doors using the smart key system may not be possible
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 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
second 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 system will not start even after multiple attempts, contact your Toyota
dealer.
CAUTION
■ Chemicals in the battery
Batteries contain poisonous and corrosive sulfuric acid and may produce
hydrogen gas which is flammable and explosive. To reduce the risk of death
or serious injury, take the following precautions while working on or near the
battery:
● Do not cause sparks by touching the battery terminals with tools.
● Do not smoke or light a match near the battery.
● Avoid contact with eyes, skin and clothes.
● Never inhale or swallow electrolyte.
● Wear protective safety glasses when working near the battery.
● Keep children away from the battery.

CAUTION
■
Caution while towing
● Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelets and the cables or chains. Always
be cautious of the surroundings and other vehicles while towing.
● Vehicles with a smart key system: Do not turn the “ENGINE START
STOP” switch off.
Doing so will lock the steering wheel and prevent operation, possibly caus-
ing an accident and resulting in death or serious injury.
● If the engine is not running, the power assist for the brakes and steering
will not function, making steering and braking more difficult.
NOTICE
■To prevent causing serious damage to the transmission and transfer
(4WD models) when towing using a wheel-lift type truck
2WD models: Never tow this vehicle from the front with the rear wheels on
the ground.
4WD models: Never tow this vehicle with any of the wheels in contact with
the ground.
■ To prevent damage to the vehicle when towing using a wheel-lift type
truck
● 2WD models without a smart key 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.
● 2WD models with a smart key system: Do not tow the vehicle from the rear
when the “ENGINE START STOP” switch is off. The steering lock mecha-
nism 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.
