■ Temporary cancellation of functions
When operation conditions are no longer met, a function may be temporarily
canceled. However, when the operation conditions are met again, operation
of the function is automatically restored. ( P. 358)
■ Yaw assist function
● Depending on the vehicle speed, lane departure situation, road conditions,
etc., the driver may not feel the func tion is operating or the function may not
operate at all.
● The yaw assist of the function is overridden by the driver’s steering wheel
operation.
● Do not attempt to test the operation of the yaw assist function.
● A sound may be heard from the engine compartment when the brake pedal
is depressed, when the yaw assist function is operating. This sound does
not indicate that a malfunction is occurred in the LDA system.
■ Lane departure alert function
● The warning buzzer may be difficult to hear due to external noise, audio
playback, etc.
● If the edge of the course* is not clear or straight, the lane departure alert
function may not operate.
● Do not attempt to test the operation of the lane departure alert function.
*: Boundary between asphalt and the side of the road, such as grass, soil,
or a curb
■ Vehicle sway warning function
Depending on the vehicle and road conditions, the warning may not operate.
When the system determines that the
vehicle is swaying while the vehicle sway
warning function is operating, a buzzer
sounds and a warning message urging
the driver to rest and the symbol shown in
the illustration are simultaneously dis-
played on the multi-information display.

■ Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly
In the case of the following conditions, operate the brake pedal (or accelera-
tor pedal, depending on the situation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system
may not operate properly.
● When the vehicle ahead of you decelerates suddenly
● When driving on a road surrounded by a structure, such as in a tunnel or on
a bridge
● While the vehicle speed is decreasing to the set speed after the vehicle
accelerates by depressing the accelerator pedal
● When the road curves or when the lanes
are narrow
● When steering wheel operation or your
position in the lane is unstable

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)
■ Unlocking the rear differential
If the rear differential lock indicator still flashes even after unlocking the rear
differential, check the safety of the surrounding area and 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.
