NOTICE
To prevent the battery from being
discharged, do not use the power
outlet longer than necessary when
the engine is not running.
 Close the power outlet lid when the
power outlet is not in use. Inserting
a foreign object other than the ap-
propriate plug that fits the outlet
may cause electrical failure or short
circuit.
The power outlet is not designed for
the following electric appliances even if
their power consumption is under 115
VAC/100W. These appliances may not
operate properly.
Appliances with high initial peak watt-
age: cathode− ray tube type televisions,
compressor −driven refrigerators, electric
pumps, electric tools, etc.
Measuring devices which process pre-
cise data: medical equipment, measur-
ing instruments, etc.
Other appliances requiring an extremely
stable power supply: microcomputer −
controlled electric blankets, touch sen-
sor lamps, etc.
Certain electrical appliances may cause
radio noise.
You can enjoy the rear seat entertain-
ment system with commercial head-
phones.
To use the headphones, connect them to
the jack.
The key must be in the “ACC” or “ON”
position.
To adjust the volume of the headphones,
turn the dial.
Left side dial: Turn it upward to increase
the volume, turn it downward to decrease
the volume.
Right side dial: Turn it downward to in-
crease the volume, turn it upward to de-
crease the volume.

1. Outside temperature (“OUTSIDE C”
or “OUTSIDE F”)
The outside temperature display indi-
cates the outside air temperature.
The displayed value is updated every 1
second.
The displayed temperature ranges from
− 30 C ( −22 F) up to 50 C (122 F).
If an abnormality exists in the connection
of the outside air temperature sensor,
“ −− C” (“ −−F”) will appear on the display.
If “ −−C” (“ −−F”) appears on the display,
contact your Toyota dealer.
There may be a case that “−− C” (“ −−F”)
appears momentarily when the ignition is
quickly turned to “ON”. It is normal if it
goes out soon.
2. Average fuel consumption (“AVG MPG” or “AVG L/100 km”)
Average fuel consumption is calculated
and displayed based on total driving
distance and total fuel consumption
with the engine running.
The displayed value is updated every 1
seconds.
To reset the calculations, return the mode
to “AVG” and push and hold the “MODE”
and “E/M” button simultaneously for 2 sec-
onds. 3. Instantaneous fuel consumption
(“INST MPG” or “INST L/100 km”)
The instantaneous fuel consumption is
calculated and displayed based on dis-
tance and fuel consumption for 1 sec-
onds with the engine running.
The displayed value is updated every 2
seconds.
Note that an accurate figure may not be
shown in the following cases.
The vehicle is stopped with the engine
running. (The display will indicate the
extremely high fuel consumption.)
The vehicle is driving down a long
slope applying the engine brake. (The
display will indicate the extremely low
fuel consumption.)
The calculation is reset when the ignition
switch is turned off. 4. Distance to empty (“DTE MI” or “DTE km”)
The distance the vehicle can travel with
the remaining fuel is calculated and
displayed based on the quantity of re-
maining fuel and past fuel consumption.
The displayed value is updated every 1
second. Every time you refuel the vehicle, the cal-
culation is reset.
The actual driving range varies with driv-
ing habits and road conditions. If fuel con-
sumption is good, the driving range will be
longer. If fuel consumption is poor, the
driving range will be shorter.

In the following cases, the system may
not work properly.
When ice, snow, mud or other objects
build up on the sensor.
When the vehicle is parked in extreme-
ly high or extremely low temperature
for a long period.
When driving on bumpy or graveled
roads or on grass
When a device such as a horn from
another vehicle, motorcycle engine, or
an air brake sound from a heavy −duty
vehicle, issues ultrasonic waves, near
your vehicle
When attaching a two −way radio anten-
na
When rain or water splashes on the
sensor.
When operating the vehicle on an in-
clined surface
When a radio antenna or fender pole
is mounted on your vehicle.
When a towing hitch is mounted on
your vehicle. The system may not detect the follow-
ing.
Thin objects such as a wire or rope
Objects with a surface area too small
to reflect ultrasonic waves such as
wire gauze
Sound wave absorbing objects or mate-
rial such as cotton or snow
A person near the vehicle (depending
on the type of clothes worn)
Objects with a sharp edge
Small or short objects
Tall objects with an upper part project-
ing toward the vehicle
Objects just under the bumper
Objects very close to your vehicle
In the following cases, have your
Toyota dealer check the system.
When the bumper is damaged.
When the indicator is continuously on.
1: Rear sensors
2: Rear corner sensors
The Toyota park assist system is de-
signed to inform you of the approxi-
mate distance between your vehicle and
an obstruction by indicator and buzzer
when parking the vehicle. This system
uses sensors to detect obstructions.
This system works when the ignition key
is at the “ON” position and the transmis-
sion is in the “R” position.
The sensors work only when the transmis-
sion is in the “R” position.

CAUTION
The Toyota park assist system is
intended as an aid to assist you to
park and is not a substitute for
your personal judgment. Make your
driving decisions based on your ob-
servations.
Do not attach accessories or other
objects to the vehicle within the
sensor perceptible area. Doing so
may cause the system to malfunc-
tion, which might result in an acci-
dent.
In certain situations, the system
will not function properly and when
the vehicle approaches certain ob-
jects, the system will not detect
those objects. Therefore, always ob-
serve the area around the vehicle
and do not rely solely on the sys-
tem.
For vehicles sold in Canada
This ISM device compiles with
Canadian ICES001.
In the following cases, the system may
not work properly.
When ice, snow, mud or other objects
build up on the sensor.
When the vehicle is parked in extreme-
ly high or extremely low temperature
for a long period.

Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
break−in. But following a few simple tips
for the first 1600 km (1000 miles) can add
to the future economy and long life of
your vehicle:
Avoid full throttle acceleration when
starting and driving.
Avoid racing the engine.
Try to avoid hard stops during the first
300 km (200 miles).
Do not drive for a long time at any
single speed, either fast or slow.
Do not tow a trailer during the first 800
km (500 miles). FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mix
−ups, your
Toyota has a smaller fuel tank opening.
The special nozzle on pumps with un-
leaded fuel will fit it, but the larger stan-
dard nozzle on pumps with leaded gas will
not.
At a minimum, the gasoline you use
should meet the specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5 −M93
in Canada.NOTICE
Do not use leaded gasoline. Use of
leaded gasoline will cause the three
way catalytic converter to lose its ef-
fectiveness and the emission control
system to function improperly. Also,
this can increase maintenance costs.
OCTANE RATING
Select Octane Rating 87 (Research
Octane Number 91) or higher. For
improved vehicle performance, use
premium unleaded gasoline with an
Octane Rating of 91 (Research Octane
Number 96) or higher.
Use of unleaded gasoline with an octane
rating or research octane number lower
than stated above will cause persistent
heavy knocking. If it is severe, this will
lead to engine damage.
If your engine knocks...
If you detect heavy knocking even when
using the recommended fuel, or if you
hear steady knocking while holding a
steady speed on level roads, consult your
Toyota dealer.
However, occasionally, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is normal
and there is no need for concern.
