●In the following si tuations, the cor-
rect outside tempe rature may not
be displayed, or the display may
take longer than normal to
change.
• When stopped, or driving at low
speeds (less than 12 mph [20
km/h])
• When the outside temperature
has changed suddenly (at the
entrance/exit of a garage, tunnel,
etc.)
●When “--” or “E” is displayed, the

Vehicle status information and indicators
■Display items
 Odometer
Displays the total distance the vehi-
cle has been driven.
 Trip meter A/Trip meter B
Displays the distance the vehicle
has been driven since the meter
was last reset. Trip meters A and B
can be used to record and display
different distances independently.
Distance until next engine oil
change

necessary.
■Changing the display
Each time the “ODO TRIP”
switch is pressed, the displayed
item will be changed. When the
trip meter is displayed, pressing
and holding the switch will reset
the trip meter.
WARNING
For example, there is a lag
between the driver’s shifting and
the new gear number appearing
on the display. This lag could
cause the driver to downshift
again, causing rapid and exces-
sive engine braking and possibly
an accident resulting in death or
injury.
NOTICE
■To prevent damage to the
engine and its components
●Do not let the i ndicator needle
of the tachomete r enter the red
zone, which indicates the maxi-
mum engine speed.
●The engine may be overheating
if the engine coolant tempera-
ture gauge is in the red zone
(H). In this case, immediately
stop the vehicle in a safe place,
and check the engine after it
has cooled completely.
(  P.535)
■Voltmeter
When the voltmeter indicates 19
V or higher or 9 V or lower while
the hybrid system is operating,
there may be a 12- volt battery or
charging system malfunction.
Have the vehicle inspected at
your Toyota dealer.
■Engine oil pressure gauge
When the value of the engine oil
pressure gauge drops while the
engine is running, stop the vehicle
in a safe place immediately and
check the amoun t of engine oil.
(  P.458)
When the oil pressure drops even
though the engine oil amount has
not decreased, or i f the oil pres-
sure does not increase when
engine oil is added, contact your
Toyota dealer, as there may be a
problem with the lubrication sys-
tem.

■Conditions affecting operation
The smart key 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 key system, wireless remote
control and immobilizer system from
operating properly. (Ways of coping:
 P.527)
●When the electronic key battery is
depleted
●Near a TV tower, electric power
plant, gas station , radio station,
large display, airpo rt or other facil-
ity that generates strong radio
waves or electrical noise
●When carrying a portable radio,
cellular phone, cordless phone or
other wireless communication
device
●When the electronic key is in con-
tact with, or is covered by the fol-
lowing metallic objects
• Cards to which al uminum foil is
attached
• Cigarette boxes that have alumi- num foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When other wireless keys (that
emit radio waves) are being used
nearby
●When carrying the electronic key
together with the following devices
that emit radio waves
• Another electronic key or a wire- less key that emits radio waves
• Personal computers or personal
digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic con-
tent or metallic objects are
attached to the rear window
●When the electronic key is placed
near a battery charger or elec-
tronic devices
●When the vehicle is parked in a
pay parking spot where radio
waves are emitted.
■Note for the entry function
●Even when the electronic key is
within the effective range (detec-
tion areas), the system may not
operate properly in the following
cases:
• The electronic key is too close to the window or outside door han-
dle, 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 center of the rear
bumper.
• The electronic key is on the instru- ment panel, or floor, or in the door
pockets or glove box when the
hybrid system is started or power
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 reception conditions, it may
be detected by the antenna out-
side the cabin and the doors 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 electronic key
can be used to unlock the vehicle.
●Even if the electro nic key is not
inside the vehicle, it may be possi-
ble to start the hybrid system 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 effec-
tive range. (The doors will auto-
matically be locked after
approximately 60 seconds if the
