Before refueling the vehicle
WARNING
■When refueling the vehicle
Observe the following precautions
while refueling the vehicle. Failure to do so may result in death or serious injury.
●After exiting the vehicle and before opening the fuel door, touch an
unpainted metal surface to dis- charge any static electricity. It is important to discharge static elec-
tricity before refueling because sparks resulting from static electric-ity can cause fuel vapors to ignite
while refueling.
●Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened. Wait until the sound cannot be
heard before fully removing the cap. In hot weather, pressurized fuel may spray out the filler neck
and cause injury.
●Do not allow anyone that has not
discharged static electricity from their body to come close to an open fuel tank.
●Do not inhale vaporized fuel.Fuel contains substances that are
harmful if inhaled.
●Do not smoke while refueling the
vehicle. Doing so may cause the fuel to ignite and cause a fire.
●Do not return to the vehicle or touch any person or object that is stati-
cally charged. This may cause static electricity to build up, resulting in a possible igni-
tion hazard.
■When refueling
Observe the following precautions to prevent fuel overflowing from the fuel tank:
●Securely insert the fuel nozzle into the fuel filler neck.
●Stop filling the tank after the fuel nozzle automatically clicks off.
●Do not top off the fuel tank.

• When multiple vehicles are approach-
ing with only a small gap between
each vehicle
• When the distance between your vehi-
cle and a following vehicle is short
• When there is a significant difference
in speed between your vehicle and
the vehicle that enters the detection
area
• When the difference in speed
between your vehicle and another
vehicle is changing
• When a vehicle enters a detection
area traveling at about the same
speed as your vehicle
• As your vehicle starts from a stop, a
vehicle remains in the detection area
• When driving up and down consecu-
tive steep inclines, such as hills, dips
in the road, etc.

●Instances of the Blind Spot Monitor unnecessarily detecting a vehicle
and/or object may increase in the fol- lowing situations:• When the sensor is misaligned due to
a strong impact to the sensor or its surrounding area• When the distance between your vehi-
cle and a guardrail, wall, etc., that enters the detection area is short• When driving up and down consecu-
tive steep inclines, such as hills, dips in the road, etc.• When vehicle lanes are narrow, or
when driving on the edge of a lane, and a vehicle traveling in a lane other than the adjacent lanes enters the
detection area • When driving on roads with sharp bends, consecutive curves, or uneven
surfaces • When the tires are slipping or spinning• When the distance between your vehi-
cle and a following vehicle is short • When an accessory (such as a bicycle carrier) is installed to the rear of the

■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.
