Driving
Opening the fuel tank cap
●Close all the doors and windows, and turn the engine switch to the
“LOCK” position (vehicles without a smart key system) or off (vehi-
cles with a smart key system).
● Confirm the type of fuel.
■Fuel type
P. 609
■ Fuel tank opening for unleaded gasoline
To  help  prevent  incorrect  fueling,  your  vehicle  has  a  fuel  tank  opening  that
only accommodates the special nozzle on unleaded fuel pumps.
Perform the following steps  to open the fuel tank cap:
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 discharge any static electricity. It is important to
discharge  static  electricity  before  refueling  because  sparks  resulting  from
static electricity 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 of 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 statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.

4-4. Refueling
Pull  up  the  opener  to  open  the
fuel filler door.
Turn  the  fuel  tank cap slowly  to
remove  it  and  hang  it  on  the
back of the fuel filler door.
WARNING
■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.
NOTICE
■Refueling
Do not spill fuel during refueling.
Doing  so  may  damage  the  vehicle,  such  as  causing  the  emission  control
systems to operate abnormally or damaging fuel system components or the
vehicle’s painted surface.

Driving
After  refueling,  turn  the  fuel  tank
cap  until  you  hear  a  click.  Once

slightly in the opposite direction.
Closing the fuel tank cap
WARNING
■When replacing the fuel tank cap
Do  not  use  anything  but  a  genuine  Toyota  fuel  tank  cap  designed  for  your
vehicle.  Doing  so  may  cause  a  fire  or  other  incident  which  may  result  in
death or serious injury.

7-2. Maintenance
Emission inspection and maintenance (I/M) 
programs
The OBD system determines that a problem exists somewhere in the
emission  control  system.  Your  vehicl e  may  not  pass  the  I/M  test  and
may  need  to  be  repaired.  Contact  your  Toyota  dealer  to  service  the
vehicle.
● When the battery is disconnected or discharged
Readiness codes that are set duri ng ordinary driving are erased.
Also,  depending  on  your  driving  habits,  the  readiness  codes  may
not be completely set.
● When the fuel tank cap is loose
The  malfunction  indicator  lamp  comes  on  indicating  a  temporary
malfunction and your vehicle may not pass the I/M test.
The error code in the OBD system  will not be cleared unless the vehi-
cle is driven 40 or more times.
Contact your Toyota dealer to prepare the vehicle for re-testing.
Some states have vehicle emission inspection programs which
include OBD (On Board Diagnos tics) checks. The OBD system
monitors the operation of  the emission control system.
If the malfunction indicator lamp comes on
Your vehicle may not pass the I/M test in the following situations:
When the malfunction indicator lamp still remains on after sev-
eral driving trips
If your vehicle does not pass the I/M test

Maintenance and care
Tire valve
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure usi ng the gauge gradations.
If the tire inflation pressure is  not at the recommended level, adjust
the pressure.
If you add too much air, press the center of the valve to deflate.
After  completing  the  tire  inflation  pressure  measurement  and
adjustment, apply soapy water to  the valve and check for leakage.
Put the tire valve cap back on.
■Tire inflation pressure check interval
You should check tire inflation pressure every two weeks, or at least once
a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrect tire  inflation pressure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating, have it checked by your Toyota dealer.
