VEHICLETOVEHICLE DISTANCE
CONTROL MODE FAILURE WARNING
If there is trouble somewhere in the dy-
namic laser cruise control while the ve-
hicle−to −vehicle distance control mode is
on, the master warning light comes on
and the alarm sounds, and one of the
warning codes “E1”, “E2” or “E3” will ap-
pear on the display. Dynamic laser cruise
control is automatically cancelled.
If “E3” appears on the display, the
“CRUISE” indicator light in the instrument
cluster also flashes. If “E1” appears on the display,
the sys-
tem cannot easily measure the vehicle −to −
vehicle distance because of a dirty laser
radar sensor glass while the dynamic la-
ser cruise control is on.
If this code appears, clean the sensor
glass with a soft cloth and try setting the
preset speed again. If the dirt is removed
without cleaning, the system will automati-
cally enter the ready mode.
If the system does not enter the ready
mode even after cleaning or the code re-
mains on the display, the system might be
malfunctioning. Although there is no prob-
lem to continue driving, please contact
your Toyota dealer.
CAUTION
Always keep the sensor glass and
never allow it to be covered with
icicle or any substance, so it can de-
tect the vehicle in front.
If “E2” appears on the display, the sys-
tem cannot easily measure the vehicle −to −
vehicle distance because of the following
conditions:
The wipers are operating at high or low
speeds
Direct sunlight from the front
It is difficult to make a measurement
because of bad weather (such as rainy,
foggy, or snowy weather)
In the following cases, dynamic laser
cruise control switches to the ready mode:
The wipers are stopped or are
switched to intermittent operation.
No direct sunlight from the front
In the above conditions, push the lever up
in the “+ RES” direction and release it.
Dynamic laser cruise control will be re-
stored. If the setting operation cannot be
performed or if the warning code still ap-
pears even after the weather clears, the
system might have malfuncti oned. Al-
though there is no problem to continue
driving, contact your Toyota dealer.

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 engine
switch 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 engine
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. However, when only a
small amount of fuel is added to the tank,
the display may not be 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.

The compass sensor is on the roof of
the vehicle.
NOTICE
Do not put magnets or a metal object
on or near the roof of the vehicle.
Doing this may cause malfunction of
the compass sensor.
CALIBRATING THE COMPASS (deviation
calibration)
The direction display on the compass
deviates from the true direction deter-
mined by the earth’s magnetic field. The
angle of deviation varies according to the
geographic position of the vehicle.
To adjust for this deviation;1. Stop the vehicle in a level place and switch the display to the outside tem-
perature. (To switch to this mode, see
“—Outside temperature and cruise in-
formation display” on page 376.)
2. Push and hold both the “MODE” and “E/M” buttons simultaneously for 5 sec-
onds until the “VAR” indication appears
on the compass display.
3. Push the “E/M” button several times until the desired zone number appears
on the compass display.
If the button is not pushed for 10 sec-
onds, the display returns to the compass/
outside temperature mode and the number
that is last set is memorized.
To select the zone where the vehicle is
currently located, refer to the following
map.

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.

Perceptible area
A: Approximately 1800 mm (70.9 in.)
B: Approximately 850 mm (33.5 in.)
C: Approximately 600 mm (23.6 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
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.
