The  SRS  airbag  and  seat  belt  pretensioner  devices  in  your  Toyota  contain
explosive chemicals. If the vehicle is scrapped with the airbags and seat belt
pretensioners  left  as  they  are,  this  may  cause  an  accident  such  as  fire.  Be
sure  to  have  the  systems  of  the  SRS  airbag  and  seat  belt  pretensioner
removed and disposed of by a qualified service shop or by your Toyota dealer
before you scrap your vehicle.
Special handling may apply, See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your  vehicle  has  components  that  may  contain  perchlorate.  These  compo-
nents  may  include  airbag,  seat  belt  pretensioners,  and  wireless  remote  con-
trol batteries.

WARNING
■General precautions while driving
Driving under the  influence:  Never drive  your vehicle when  under  the  influ-
ence of alcohol or drugs that have impaired your ability to operate your vehi-
cle.  Alcohol  and  certain  drugs  delay  reaction  time,  impair  judgment  and
reduce  coordination,  which  could  lead  to  an  accident  that  could  result  in
death or serious injury.
Defensive  driving: Always  drive  defensively. Anticipate  mistakes  that  other
drivers or pedestrians might make and be ready to avoid accidents.
Driver  distraction:  Always  give  your  full  attention  to  driving.  Anything  that
distracts the driver, such as adjusting controls, talking on a cellular phone or
reading can result in a collision with resulting death or serious injury to you,
your occupants or others.
■General precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children  may  be  able  to  start  the  vehicle  or  shift  the  vehicle into  neutral.
There is also a  danger that  children  may  injure  themselves  by playing with
the  windows,  the  moon  roof,  or  other  features  of  the  vehicle.  In  addition,
heat build-up or extremely cold temperatures inside the vehicle can be fatal
to children.

801-3. Theft deterrent system
The  alarm  uses  light  and  sound  to  give  an  alert  when  an  intrusion  is
detected.
The  alarm  is  triggered  in  the  following  situations  when  the  alarm  is
set:
●A  locked  door  is  unlocked  or  opened  in  any  way  other  than  using
the entry function, wireless remote control or mechanical key. (The
doors will lock again automatically.)
●The trunk is opened in any way other than using the entry function
or wireless remote control.
●The hood is opened.
Close  the  doors,  trunk  and  hood,
and lock all the doors. The system
will  be  set  automatically  after  30
seconds.
The  indicator  light  changes  from
being  on  to  flashing  when  the  sys-
tem is set.
Do one of the following to deactivate or stop the alarm:
●Unlock the doors.
●Open the trunk using the entry function or wireless remote control.
●Turn the engine switch to ACCESSORY or IGNITION ON mode, or
start  the  engine.  (The  alarm  will  be  deactivated  or  stopped  after  a
few seconds.)

1383-2. Opening, closing and locking the doors
■Note for the entry function
●Even when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near
the ground, or in a high place when the doors are locked or unlocked.
• The  electronic  key  is  near  the  ground  or  in  a  high  place,  or  too  close  to
the rear bumper center when the trunk is opened.
• The electronic key is on the instrument panel, rear package tray or floor,
or in the door pockets or glove box when the engine is started or engine
switch modes are changed.
●Do  not  leave  the  electronic  key  on  top  of  the  instrument  panel or  near  the
door pockets when exiting the vehicle. Depending on the radio wave recep-
tion conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping the electronic
key inside the vehicle.
●As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.
●Even if the electronic key is not inside the vehicle, it may be possible to start
the engine if the electronic key is near the window.
●The  doors  may  unlock  or  lock  if  a  large  amount  of  water  splashes  on  the
door handle, such as in the rain or in a car wash, when the electronic key is
within  the  effective  range.  (The  doors  will  automatically  be  locked  after
approximately 60 seconds if the doors are not opened and closed.)
●If  the  wireless  remote  control  is  used  to  lock  the  doors  when  the  electronic
key  is  near  the  vehicle,  there  is  a  possibility  that  the  door  may  not  be
unlocked  by  the  entry  function.  (Use  the  wireless  remote  control  to  unlock
the doors.)
●Touching  the  door  lock  sensor  while  wearing  gloves  may  delay  or prevent
lock operation. Remove the gloves and touch the lock sensor again.
●When the lock operation is performed using the lock sensor, recognition sig-
nals  will  be  shown  up  to  two  consecutive  times. After  this,  no recognition
signals will be given.
*
●If the  door  handle becomes  wet while the  electronic  key  is within the  effec-
tive range, the door may lock and unlock repeatedly. In this case, follow the
<00490052004f004f0052005a004c0051004a00030046005200550055004800460057004c00520051000300530055005200460048004700580055004800560003005700520003005a00440056004b00030057004b0048000300590048004b004c0046004f00

• Place  the  electronic  key  in  a  location  6  ft.  (2  m)  or  more  away  from  the
vehicle. (Take care to ensure that the key is not stolen.)
• Set  the  electronic  key  to  battery-saving  mode  to  disable  the  smart  key
system. (P. 137)
●If  the  electronic  key  is  inside  the  vehicle  and  a  door  handle  becomes  wet
during  a  car  wash,  a  message  may  be  shown  on  the  multi-information  dis-
play and a buzzer will sound outside the vehicle. To turn off the alarm, lock
all the doors.

Operation of each component
●The  lock  sensor  may  not  work  properly  if  it  comes  into  contact with  ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again.
●A  sudden  approach  to  the  effective  range  or  door  handle  may  prevent  the
doors from being unlocked. In this case, return the door handle to the origi-
nal position and check that the doors unlock before pulling the door handle
again.
●If  there  is  another  electronic  key  in  the  detection  area,  it  may  take  slightly
longer to unlock the doors after the door handle is gripped.
●Fingernails  may  scrape  against  the  door  during  operation  of  the  door  han-
dle. Be careful not to injure fingernails or damage the surface of the door.
*: This setting can be customized at your Toyota dealer.
■When the vehicle is not driven for extended periods
●To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2
m) of the vehicle.
●The smart key system can be deactivated in advance. (P. 505)
●Setting  the  electronic  key  to  battery-saving  mode  helps  to  reduce  key  bat-
tery depletion. (P. 137)
■To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from the
outside of the vehicle.
Depending on the position and holding condition of the electronic key, the key
may not be detected correctly and the system may not operate properly. (The
alarm  may  go  off  accidentally,  or  the  door  lock  prevention  function  may  not
operate.)

Maintenance and care
Check the battery as follows.
■Battery exterior
Make  sure  that  the  battery  terminals  are  not  corroded  and  that
there are no loose connections, cracks, or loose clamps.
Terminals
Hold-down clamp
■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following 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 dis-
connecting the charger cables to the battery.
■After recharging/reconnecting the battery
●Unlocking the doors using the smart key system may not be possible imme-
diately  after  reconnecting  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 switch  in ACCESSORY mode. The engine
may  not  start  with  the  engine  switch  turned  off.  However,  the  engine  will
operate normally 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  disconnected.  Make  sure  to  turn  off  the engine
before  disconnecting the  battery. Take extra care  when connecting  the  bat-
tery if the engine switch mode prior to discharge is unknown.
If  the  system  will  not  start  even  after  multiple  attempts,  contact  your  Toyota
dealer.

4697-2. Steps to take in an emergency
7
When trouble arises
■Starting the engine when the battery 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 off.
●Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
■When the battery is removed or discharged
●Information stored in the ECU is cleared. When the battery is depleted, have
the vehicle inspected at your Toyota dealer.
●Some systems may require initialization. (P. 513)
■When removing the battery terminals
When the battery terminals are removed, the information stored in the ECU is
cleared. Before removing the battery terminals, contact your Toyota dealer.
■Charging the battery
The  electricity  stored  in  the  battery  will  discharge  gradually even  when  the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle 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
●In  some  cases,  it  may  not  be  possible  to  unlock  the  doors  using the smart
key 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 malfunction.
●The  engine  switch  mode  is  memorized  by  the  vehicle.  When  the  battery  is
reconnected, the system will return to the mode it was in before the battery
was discharged. Before disconnecting the battery, turn the engine switch off. 
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.
■When replacing the battery
●Use a battery that conforms to European regulations.
●Use a battery that the case size is same as the previous one (LN3), 20 hour
rate capacity (20HR) is equivalent (70Ah) or greater, and performance rating
(CCA) is equivalent (603A) or greater.
• 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 battery may discharge and the engine
may not be able to start.
●For details, consult your Toyota dealer.
