■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the fol- lowing precautions 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 disconnecting the charger cables to the battery.
■After recharging/reconnecting the
battery (vehicles with a smart entry & start system)
●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 ACC. The engine may not
start with the engine switch turned off. However, the engine will operate nor-mally 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 discon-nected. Make sure to turn off the
engine before disconnecting the bat- tery. 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 autho-
rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.

If your vehicle needs to
be towed
If towing is necessary, we rec-
ommend having your vehicle
towed by any authorized
Toyota retailer or Toyota autho-
rized repairer, or any reliable
repairer or commercial towing
service, using a wheel-lift type
truck or flatbed truck.
Use a safety chain system for
all towing, and abide by all
state/provincial and local laws.
WARNING
Observe the following precautions. Failure to do so may result in death or serious injury.
■When towing the vehicle
Be sure to transport the vehicle with
the front wheels raised or with all four wheels raised off the ground. If the vehicle is towed with the front wheels
contacting the ground, the drivetrain and related parts may be damaged.
■While towing
●When towing using cables or chains, avoid sudden starts, etc.
which place excessive stress on the towing eyelets, cables or chains. The towing eyelets, cables or
chains may become damaged, bro- ken debris may hit people, and cause serious damage.
●Do not turn the engine switch off.There is a possibility that the steer-
ing wheel is locked and cannot be operated.
■Installing towing eyelets to the vehicle
Make sure that towing eyelets are
installed securely. If not securely installed, towing eye-lets may come loose during towing.
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 off. The steering lock mechanism is not
strong enough to hold the front wheels straight.
●When raising the vehicle, ensure adequate ground clearance for tow-ing at the opposite end of the raised
vehicle. Without adequate clear- ance, the vehicle could be dam-aged 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.
