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 engine
switch is in the “ON” position and the
transmission is not in the “P” position.
Rear and rear corner sensors work
only when the transmission is in the
“R” position.
Front corner sensors works when the
transmission is in the “R” position.
Front corner sensors works when the
transmission is not in the “P” or “R”
position and vehicle speed is approxi-
mate 10 km/h (6 mph) or less.
To turn on: Push the switch.
The indicator comes on and the buzzer
will sound.
To turn off: Push the switch again.In the following cases, the buzzer will
sound several times and the indicator
will stay on to indicate that the system
is not working properly.
When the temperature is extremely low.
When any of the sensors are malfunc-
tion.
If the indicator is continuously on, have
your Toyota dealer check the system.
If the indicator remains blinking but
you do not hear the buzzer sound,
clean the sensors with soft cloth.

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.
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

Perceptible area
A: Approximately 1800 mm (70.9 in.)
B: Approximately 850 mm (33.5 in.)
Perceptible area is limited as shown in
the previous illustration. Check the area
around the vehicle before driving and start
driving slowly.
The maximum detection distance of the
sensor varies depending on the size of
the obstacle. The sensor can detect a
large obstacle, such as a wall, up to 1800
mm (70.9 in.) away. However, the detec-
tion distance of a thin obstacle, such as
a pole, is less than 1800 mm (70.9 in.).CAUTION

IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in prop-
er vehicle maintenance is to keep the en-
gine oil at the optimum level so that oil
function will not be impaired. Therefore, it
is essential that the oil level be checked
regularly. Toyota recommends that the oil
level be checked every time you refuel
the vehicle.
NOTICE
Failure to check the oil level regularly
could lead to serious engine trouble
due to insufficient oil.
For detailed information on oil level check,
see “Checking the engine oil level” on
page 518 in Section 7−2.
Long reach
type
Your engine is fitted with long reach
iridiumtipped spark plugs.
NOTICE
Use only Toyota genuine long reach
iridiumtipped spark plugs and do not
adjust gaps for your engine perfor-
mance and smooth driveab ility.
For details about the spark plug type, see
“Service specifications” on page 550 in
Section 8. The tandem master cylinder brake system
is a hydraulic system with two separate
sub
−systems. If either sub −system s hould
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will increase. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power −assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserved
vacuum for one or two stops—but no
more!
