If a vehicle is detected ahead of you—2. Deceleration cruising function: If a
slower moving vehicle is detected
ahead of you, your vehicle cruising
speed decreases within the range of
about 40 km/h (25 mph) to about 135
km/h (85 mph). The display shows the
preset speed, the detected vehicle
ahead and selected vehicle −to −vehicle
distance. If your vehicle gets closer to
the vehicle ahead because of insuffi-
cient automatic deceleration, then the
alarm warns you to also manually ap-
ply brakes.
3. Followup cruising function: After de-
celeration, your vehicle cruising speed
changes in proportion to the speed of
the vehicle ahead to maintain an ap-
propriate distance from your vehicle to
the vehicle ahead. The vehicle −to −ve-
hicle distance can be changed. For de-
tails, see “CHANGING VEHICLE −TO −
VEHICLE DISTANCE” on page 225.
4. Acceleration cruising function: If the
vehicle ahead changes lanes, your ve-
hicle cruising speed will be gradually
increased up to the preset speed, and
your vehicle resumes fixed −speed
cruising. This system operates by detecting pri-
marily the reflectors of the vehicle
ahead. The distance may not be accu-
rately or absolutely detected in the fol-
lowing cases:
The vehicle ahead has higher ground
clearance, which means that the
placement of the reflectors is in a
higher position.
The rear section of the vehicle ahead
is extremely dirty.
The vehicle ahead or other vehicles
around you are flinging up water or
snow.
Excessive exhaust gas (black smoke)
is coming from the vehicle ahead or
other vehicles around you, obscuring
your front view.
There is an obstruction (protective
film, sticker, etc.) on the reflectors
on the vehicle ahead, or reflectors
are not installed on the vehicle
ahead or are damaged.
Heavy luggage in the luggage
compartment or rear seats is caus-
ing the nose of your vehicle to tilt
up.
CAUTION
To avoid accidents, always keep the
laser radar sensor glass clean and
never allow it to be covered with
icicle or any substance, so it can de-
tect the vehicle in front. (See “LASER
RADAR SENSOR” on page 226.)

CAUTION
Do not rely excessively on dynamic
laser cruise control. Observe the fol-
lowing precautions in order to avoid
serious injury or death:
Under certain conditions where the
vehicle in front slows drastically, or
is stopped, the dynamic laser cruise
control will neither warn you nor
decelerate. You must depress the
brake pedal to slow down, ensuring
collision avoidance or that suffi-
cient vehicletovehicle distance is
maintained.
Do not use dynamic laser cruise
control in the following conditions:
In bad weather (such as rain, fog,
snow, sandstorms or direct sun-
light, or when raindrops or snow-
flakes get on the laser radar sensor
glass), the vehicletovehicle dis-
tance will not be measured accura-
tely.
When using the windshield wipers
at high or low speeds the dynamic
laser radar cruise control turns off.
On roads with heavy traffic or
sharp bends, an appropriate speed
cannot be maintained and an acci-
dent may occur.
On slippery road surfaces (icy or
snowcovered road surfaces), the
tires will race and you will be un-
able to control the vehicle.
When there is no vehicle detected
ahead on steep downhill slopes, the
preset speed will be easily exceed-
ed because of inefficient engine
braking. (In this case, automatic
braking will not work.) If there is a
vehicle detected ahead, the delay in
deceleration timing could cause se-
rious injury or death.
When the alarm sounds frequently
(because acceleration or decelera-
tion was repeated or sufficient ve-
hicletovehicle distance was not
maintained), an appropriate vehicle
speed cannot be attained and an
accident may occur.On roads with steep and short in-
clines and declines, failure to de-
tect the vehicle ahead will shorten
the distance between your vehicle
and the vehicle ahead and an acci-
dent may occur.
Deceleration cruising function and
approach warning do not operate
when the vehicle ahead is at a stop
or driving very slowly.
If the vehicle ahead of you deceler-
ates abruptly or if another vehicle
cuts in ahead of you, your vehicle
may collide with the vehicle ahead
unless you manually depress the
brake pedal to slow down your ve-
hicle.

Braking control is operating only when the
vehicle−to −vehicle distance control mode
is selected and your vehicle speed ex-
ceeds about 40 km/h (25 mph). If the
speed decreases below about 40 km/h (25
mph), braking control will cease, requiring
the manual application of brakes.
CAUTION
Braking control will not ensure that
your vehicle will reduce speed ap-
propriately. You must depress the
brake pedal to slow down, ensuring
collision avoidance or that sufficient
vehicletovehicle distance is main-
tained.
APPROACH WARNING
While you are cruising in the vehicle −to −
vehicle distance control mode, if the ve-
hicle ahead decelerates abruptly or if
another vehicle cuts in ahead of you, in-
adequate braking will make your vehicle
become closer to the vehicle ahead of you
and the display will flash and beep.
CAUTION
If the display flashes and beeps,
you must depress the brake pedal
to slow down to avoid a collision
or maintain sufficient vehicletove-
hicle distance.
In the following conditions, the ap-
proach warning may not turn on
even if the vehicle drives closer to
the vehicle ahead, and an accident
may occur:
Your vehicle and the vehicle ahead
are cruising at almost the same
speed.
The vehicle ahead is cruising at a
faster speed than yours. (The dis-
tance between the vehicles will be-
come longer.)
The vehicle ahead is at a stop or
driving very slowly. Pay special
attention to a very slow vehicle at
the end of the line in heavy traffic
or at a tollgate.
The speed has just been set.
The accelerator pedal is depressed
or has just been released.
LASER RADAR SENSOR
The laser radar sensor is used for ve-
hicletovehicle distance control cruis-
ing.
If dirt is on the sensor glass, the
dynamic laser cruise control function is
automatically cancelled and a warning
code appears on the display. (See
“VEHICLETOVEHICLE DISTANCE
CONTROL MODE FAILURE WARNING”
on page 227.)
However, if the glass sensor is covered
with icicle or any substance, dirt may
not be detected.

Before driving in the vehicletovehicle
distance control mode, make sure the
radar sensor glass is clean.
This product is a class I laser product
complied with 21 C.F.R part 1040.10
and 1040.11.
CAUTION
To ensure that dynamic laser cruise
control will function properly while
driving, observe the following:
Always keep the laser radar sensor
glass clean. When cleaning, use a
soft cloth and be careful not to
damage the sensor.
Avoid strong impacts around the la-
ser radar sensor. An incorrect laser
radar sensor alignment will result in
system malfunction. A special de-
vice is required to adjust the laser
radar sensor alignment. Be sure to
have the sensor adjusted by your
Toyota dealer.
Do not affix a sticker (including a
transparent sticker) or attach an ac-
cessory around the laser radar sen-
sor.
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.

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.

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 332.)
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 ignition key
is at the “ON” position and the transmis-
sion is not in the “P” position.
Rear and rear corner sensors work
only when the transmission is in the
“R” position.
Front corner sensors work only when
driving at approximate 10 km/h (6 mph)
or less.
When the vehicle is forwarding, the
front corner sensors work.
