while driving the vehicle. Failure to do so may result in a door opening and an occupant being
thrown out of the vehicle, resulting in death or serious injury.
●Ensure that all doors are properly closed and locked.
●Do not pull the inside door handle while driving.Be especially careful of the front
doors, as the doors may be opened even if the inside lock buttons are in the locked position.
●Set the rear door child-protector locks when children are seated in
the rear seats.
■When opening or closing a door
Check the surroundings of the vehicle such as whether the vehicle is on an incline, whether there is enough
space for a door to open and whether a strong wind is blowing. When open-ing or closing the door, hold the door
handle tightly to prepare for any unpredictable movement.
■When using the wireless remote control or the key and operating the power windows

3-2. Opening, closing and locking the doors
●Interior buzzer sounds continuously
■Battery-saving function
The battery-saving function will be acti-
vated in order to prevent the electronic
key battery and the vehicle battery from
being discharged while the vehicle is not
operated for a long time.
●In the following situations, the smart
entry & start system may take some
time to unlock the doors.
• The electronic key has been left within
approximately 3.5 m (11 ft.) of the out-
side of the vehicle for 2 minutes or
longer.
• The smart entry & start system has
not been used for 5 days or longer.
●If the smart entry & start system has
not been used for 14 days or longer,
the doors cannot be unlocked from
any door except the driver’s door. In
this case, hold the driver’s door han-
dle, or use the wireless remote control
or mechanical key to unlock the
doors.
■Electronic key battery-saving func-
tion
●When battery-saving mode is set, bat-
tery depletion is minimized by stop-
ping the electronic key from receiving
radio waves.
Press twice while pressing and holding . Confirm that the electronic
key indicator flashes 4 times.
While the battery-saving mode is set,
the smart entry & start system cannot be
used. To cancel the function, press any
of the electronic key buttons.
●Electronic keys that will not be used
for long periods of time can be set to
the battery-saving mode in advance.
■Conditions affecting operation
The smart entry & start system uses
weak radio waves. In the following situa-
tions, the communication between the
electronic key and the vehicle may be
affected, preventing the smart entry &
start system, wireless remote control
and engine immobilizer system from
operating properly. (Ways of coping:
→P.399)
●When the electronic key battery is
depleted
●Near a TV tower, electric power plant,
gas station, radio station, large dis-
play, airport or other facility that gen-
erates strong radio waves or electrical
noise

lar phone, cordless phone or other
wireless communication device
●When the electronic key is in contact
with, or is covered by the following

4 Start the engine of the second
vehicle. Increase the engine
speed slightly and maintain at
that level for approximately 5
minutes to recharge the battery
of your vehicle.
5 Vehicles with a smart entry &
start system: Open and close
any of the doors of your vehicle
with the engine switch OFF.
6 Maintain the engine speed of
the second vehicle and start the
engine of your vehicle by turning
the engine switch to ON.
7 Once the vehicle’s engine has
started, remove the jumper
cables in the exact reverse
order from which they were con-
nected.
Once the engine starts, have the
vehicle inspected at any autho-
rized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer as soon as possible.
■Starting the engine when the bat- tery is discharged
The engine cannot be started by push-
starting.
■To prevent battery discharge
●Turn off the headlights and the audio
system while the engine is stopped.
●Turn off any unnecessary electrical
components when the vehicle is run- ning at a low speed for an extended period, such as in heavy traffic.
■When the battery is removed or dis-charged
●Information stored in the ECU is cleared. When the battery is depleted, have the vehicle inspected at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Some systems may require initializa-tion. ( →P.431)
■When removing the battery termi-
nals
When the battery terminals are removed, the information stored in the
ECU is cleared. Before removing the battery terminals, contact any autho-rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.
■Charging the battery
The electricity stored in the battery will discharge gradually even when the vehi-
cle is not in use, due to natural dis- charge and the draining effects of certain electrical appliances. If the vehi-
cle is left for a long time, the battery may discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
■When recharging or replacing the battery (vehicles with a smart entry & start system)
●In some cases, it may not be possible to unlock the doors using the smart
entry & start system when the battery is discharged. Use the wireless remote control or the mechanical key
to lock or unlock the doors.
●The engine may not start on the first
attempt after the battery has recharged but will start normally after the second attempt. This is not a mal-
function.
●The engine switch mode is memo-
rized by the vehicle. When the battery is reconnected, the system will return

to the mode it was in before the bat-
tery was discharged. Before discon- necting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the bat-tery discharged, be especially careful
when reconnecting the battery.
■When replacing the battery
●Use a battery that conforms to Euro-
pean regulations.
●Use a battery that the case size is
same as the previous one, 20 hour rate capacity (20HR) is equivalent or greater, and performance rating
(CCA) is equivalent or greater. Check the label on top of the battery for the battery size and specifications (ex.
LN2, 60Ah, 345A). • If the sizes differ, the battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehi-cle is not used is a short time, the bat-
tery may discharge and the engine may not be able to start.
●For details, consult any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
WARNING
■When removing the battery ter-minals
Always remove the negative (-) termi-
nal first. If the positive (+) terminal contacts any metal in the surrounding area when the positive (+) terminal is
removed, a spark may occur, leading to a fire in addition to electrical shocks and death or serious injury.
■Avoiding battery fires or explo-sions
Observe the following precautions to prevent accidentally igniting the flam-mable gas that may be emitted from
the battery:
●Make sure each jumper cable is connected to the correct terminal and that it is not unintentionally in
contact with any other than the intended terminal.
●Do not allow the other end of the jumper cable connected to the “+” terminal to come into contact with
any other parts or metal surfaces in the area, such as brackets or unpainted metal.
●Do not allow the + and - clamps of the jumper cables to come into con-
tact with each other.
●Do not smoke, use matches, ciga-
rette lighters or allow open flame near the battery.
■Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following precautions when handling the bat-
tery:
●When working with the battery,
always wear safety glasses and take care not to allow any battery fluids (acid) to come into contact
with skin, clothing or the vehicle body.
●Do not lean over the battery.
●In the event that battery fluid comes
into contact with the skin or eyes, immediately wash the affected area with water and seek medical atten-
tion. Place a wet sponge or cloth over the affected area until medical attention can be received.
●Always wash your hands after han-dling the battery support, terminals,
and other battery-related parts.
●Do not allow children near the bat-
tery.
