Maintenance and care
Emission inspection and maintenance (I/M) programs
Some  states  have  vehicle  emission  inspection  programs  which
include OBD (On Board Diagnostics) checks. The OBD system moni-
tors the operation of the emission control system.
■ If the malfunction i ndicator lamp comes on
The  OBD  system  determines  that  a  problem  exists  somewhere
in the emission control system. Y our vehicle may not pass the I/
M test and may need to be repaired. Contact your Toyota dealer
to service the vehicle.
■ Your vehicle may not pass the I/M test:
●When the battery is disconnected or discharged
Readiness  codes  that  are  set  during  ordinary  driving  are
erased. 
Also,  depending  on  your  driving  habits,  the  readiness  codes
may not be completely set.
● When the fuel t ank cap is loose
The malfunction indicator lamp comes on as a temporary mal-
function and your vehicle may not pass the I/M test.
■ When  the  malfunction  indicator  lamp  goes  off  after  several
driving trips
The error code in the OBD system  will not be cleared unless the
vehicle is driven 40 or more times.
■ If your vehicle does not pass the I/M test
Contact your Toyota dealer to pr epare the vehicle for re-testing.

WARNING
The  engine  compartment  contains  many  mechanisms  and  fluids  that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
■ When working on the engine compartment
●Keep  hands,  clothing,  and  tools  away  from  the  moving  fan  and  en gine
drive belt.
● Be  careful  not  to  touch  the  engine,  radiator,  exhaust  manifold,   etc.  right
after driving as they may be hot. Oil and other fluids may also  be hot.
● Do not  leave  anything that  may burn easily,  such as  paper or ra gs,  in the
engine compartment.
● Do  not  smoke,  cause  sparks  or  expose  an  open  flame  to  fuel  or  t he  bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■ When working near the electric cooling fans or radiator grille
Vehicles  without  a  smart key  system:  Be  sure  the  engine switch  is off.  With
the  engine  switch  in  the  “ON”  position,  the  electric  cooling  fa ns  may  auto-
matically start to run if the air conditioning is on and/or the  coolant tempera-
ture is high. ( P. 337)
Vehicles  with  a  smart  key  system:  Be  sure  the  “ENGINE  START  STO P”
switch  is  off.  With  the  “ENGINE  START  STOP”  switch  in  IGNITION  ON
mode, the electric cooling fans may automatically start to run  if the air condi-
tioning is on and/or the coolant temperature is high. ( P. 337) 
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive  engine wear
due to dirt in the air.

Maintenance and care
Battery
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.
Hold-down clamp
Te r m i n a l s
■ Checking battery fluid
Check  that  the  level  is  between
“UPPER  LEVEL”  and  “LOWER
LEVEL”. 
“UPPER LEVEL”
“LOWER LEVEL”
If  the  fluid  level  is  at  or  below
“LOWER  LEVEL”,  add  distilled
water.

■Adding distilled water
Remove the vent plug.
Add distilled water.
If  the “UPPER  LEVEL”  line  cannot be  seen,  check  the  fluid  level  by
looking directly at the cell.
Put the vent plug back on and close securely.
Low O.K.
■Before recharging
When  recharging,  the  battery  produces  hydrogen  gas  which  is  fla mmable
and explosive. Therefore, before recharging:
● If  recharging  with  the  battery  installed  on  the  vehicle,  be  sur e  to  discon-
nect the ground cable.
● Make  sure  the  power  switch  on  the  charger  is  off  when  connectin g  and
disconnecting the charger cables to the battery.

Maintenance and care
■
After  recharging/reconnecting  the  battery  (vehicles  with  a  smar t  key
system)
● Unlocking  the  doors  using  the  smart  key  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 do ors.
● 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 sec-
ond 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  STAR T
STOP” switch mode prior  to discharge is unknown.
If  the  engine  will  not  start  even  after  multiple  attempts,  cont act  your Toyota
dealer.
