■Operational conditions
The pre-collision system is enabled and the system determines that the pos-
sibility of a frontal collision wi th a vehicle or pedestrian is high.
Each function is operational at the following speeds:
● Pre-collision warning:
• Vehicle speed is between approximately 10 and 180 km/h (7 and
110 mph). (For detecting a pedestrian, vehicle speed is between approxi-
mately 10 and 80 km/h [7 and 50 mph].)
• The relative speed between your vehicle and the vehicle or pedestrian
ahead is approximately 10 km/h (7 mph) or more.
● Pre-collision brake assist:
• Vehicle speed is between approximately 30 and 180 km/h (20 and
110 mph). (For detecting a pedestrian, vehicle speed is between approxi-
mately 30 and 80 km/h [20 and 50 mph].)
• The relative speed between your vehicle and the vehicle or pedestrian
ahead is approximately 30 km/h (20 mph) or more.
● Pre-collision braking:
• Vehicle speed is between approximately 10 and 180 km/h (7 and
110 mph). (For detecting a pedestrian, vehicle speed is between approxi-
mately 10 and 80 km/h [7 and 50 mph].)
• The relative speed between your vehicle and the vehicle or pedestrian
ahead is approximately 10 km/h (7 mph) or more.
The system may not operate in the following situations:
● If a battery terminal has been disconnected and reconnected and then the
vehicle has not been driven for a certain amount of time
● If the shift lever is in R
● If VSC is disabled (only the pre-collision warning function will be opera-
tional)
● If the low speed four-wheel drive indicator light is illuminated (only the pre-
collision warning function will be operational)

■ If the PCS warning light flashes or illuminates and a warning message is
displayed on the multi-information display
The pre-collision system may be tem porarily unavailable or there may be a
malfunction in the system.
● In the following situations, the warning light will turn off, the message will
disappear and the system will beco me operational when normal operating
conditions return:
• When the radar sensor or camera s ensor or the area around either sen-
sor is hot, such as in the sun
• When the radar sensor or camera s ensor or the area around either sen-
sor is cold, such as in an extremely cold environment
• When a front sensor is dirty or covered with snow, etc.
• When the part of the windshield in front of the camera sensor is fogged
up or covered with condensation or ice.
(Defogging the windshield: P. 493, 502)
• If the camera sensor is obstructed, such as when the hood is open or a
sticker is attached to the windshield near the camera sensor
● If the PCS warning light continues to flash or remains illuminated or the
warning message does not disappear even though the vehicle has returned
to normal, the system may be malfunctioning. Have the vehicle inspected by
any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer immediately.
■ If VSC is disabled
● If VSC is disabled (P. 389), the pre-collision brake assist and pre-collision
braking functions are also disabled.
● The PCS warning light will turn on and “VSC TURNED OFF PRE-COLLI-
SION BRAKE SYSTEM UNAVAILABLE”/“VSC Turned Off Pre-Collision
Brake System Unavailable” will be di splayed on the multi-information dis-
play.

WARNING
■When using the rear view monitor system
The rear view monitor system is a supplemental device intended to assist
the driver when backing up. When backing up, be sure to visually check all
around the vehicle both directly and using the mirrors before proceeding.
Observe the following precautions to avoid an accident that could result in
death or serious injuries.
● Never depend on the rear view monitor system entirely when backing up.
The image and the position of the guide lines displayed on the screen may
differ from the actual state.
Use caution, just as you would when backing up any vehicle.
● Be sure to back up slowly, depressing the brake pedal to control vehicle
speed.
● The instructions given are only guide lines.
When and how much to turn the steering wheel will vary according to traf-
fic conditions, road surface conditions , vehicle condition, etc. when park-
ing. It is necessary to be fully aware of this before using the rear view
monitor system.
● When parking, be sure to check that the parking space will accommodate
your vehicle before maneuvering into it.
● Do not use the rear view monitor system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains
• When the tailgate is not closed completely
• On roads that are not flat or straight, such as curves or slopes.
● In low temperatures, the screen may darken or the image may become
faint. The image could distort when the vehicle is moving, or you may
become unable to see the image on the screen. Be sure to visually check
all around the vehicle both directly and using the mirrors before proceed-
ing.
● If the tire sizes are changed, the position of the fixed guide lines displayed
on the screen may change.
● The camera uses a special lens. The distances between objects and
pedestrians that appear in the image displayed on the screen will differ
from the actual distances.

■Locking the rear differential
The following systems do not operate w hen the rear differential is locked.
It is normal operation for the ABS warning light, VSC OFF indicator (if
equipped) and “TRC OFF” indicator (if equipped) to be on or for “TRC
TURNED OFF”/“TRC turned off” to be displayed on the multi-information dis-
play (if equipped) at this time.
•ABS
• Brake assist (if equipped)
• VSC (if equipped)
• TRC/A-TRC (if equipped)
• Trailer Sway Control (if equipped)
• Hill-start assist control (if equipped)
• Downhill assist control (if equipped)
■ For easy unlocking
Slightly turn the steering wheel in either direction while the vehicle is in
motion.
■ Automatic system cancelation of the rear differential lock system
The rear differential lock is also unlocked in any of the following situations:
● The front-wheel drive control switch is turned to H2 or H4 (4WD models)
● The engine switch is turned to the “ACC” or “LOCK” position (vehicles with-
out smart entry & start system) or A CCESSORY or off (vehicles with smart
entry & start system)
■ After unlocking the rear differential
Check that the indicator goes off.
WARNING
■ To avoid an accident
Failure to observe the following precautions may result in an accident.
● Do not use the rear differential lock system except when wheel spinning
occurs in a ditch or on a slippery or rugged surface. Large steering effort
and careful cornering control will be required.
● Do not lock the rear differential until the wheels have stopped spinning.
Otherwise, the vehicle may move in an unexpected direction when the dif-
ferential lock is engaged, resulting in an accident. This may also lead to
possible damage to rear differential lock component parts.
● Do not drive over 8 km/h (5 mph) when the differential is locked.
● Do not keep driving with the rear differential lock switch on.

Press the Stop & Start cancel
switch to disable the Stop & Start
system.
The Stop & Start cancel indicator
will come on.
Pressing the switch again will
enable the Stop & Start system and
the Stop & Start cancel indicator
will turn off.
■Automatic reactivation of the Stop & Start system
Even if the Stop & Start system is disabled by the Stop & Start can-
cel switch, it will be automatically re-enabled once the engine
switch is turned to the “LOCK” position (vehicles without smart
entry & start system) or off (vehicles with smart entry & start sys-
tem), and then the engine is started.
■If the Stop & Start cancel switch is pressed while the vehicle is
stopped
● When the engine is stopped by the Stop & Start system, pressing
the Stop & Start cancel switch will restart the engine.
From the next time the vehicle is stopped (after Stop & Start sys-
tem has been turned off), the engine will not be stopped.
● With the Stop & Start system disabled, pressing the Stop & Start
cancel switch will re-enable the system but not stop the engine.
From the next time the vehicle is stopped (after Stop & Start sys-
tem has been turned on), the engine will be stopped.
If the engine is stopped by the Stop & Start system when the vehicle is
on an incline, brake force is temporarily maintained to prevent rolling
backwards until the engine is restarted and drive force is generated.
When drive force is generated, the maintained brake force is automat-
ically canceled.
● This function operates on flat surfaces as well as steep incline.
● Sound may be generated by the brakes, but this is not a malfunc-
tion.
● The brake pedal response may change and vibration may occur,
but these are not malfunctions.
