radio waves, such as a large truck or
guardrail
• When driving near a TV tower, broad-
casting station, electric power plant, or
other location where strong radio waves
or electrical noise may be present
■Situations in which the system may not
operate properly
●In some situations such as the following, a
vehicle may not be detected by the radar
sensor and front camera, preventing the
system from operating properly:
• If an oncoming vehicle is approaching your vehicle
• If a vehicle ahead is a motorcycle or bicy-
cle
• When approaching the side or front of a vehicle
• If a preceding vehicle has a small rear end, such as an unloaded truck
• If a preceding vehicle has a low rear end,
such as a low bed trailer
• If a vehicle ahead is carrying a load which protrudes past its rear bumper
• If a vehicle ahead has extremely high ground clearance
• If a vehicle ahead is irregularly shaped, such as a tractor or side car
• If the sun or other light is shining directly
on a vehicle ahead
• If a vehicle cuts in front of your vehicle or emerges from beside a vehicle
• If a vehicle ahead makes an abrupt maneuver (such as sudden swerving,
acceleration or deceleration)
• When suddenly cutting behind a preced- ing vehicle
• When a vehicle ahead is not directly in front of your vehicle
• When driving in incl ement weather such
as heavy rain, fog, snow or a sandstorm
• When the vehicle is hit by water, snow,
dust, etc. from a vehicle ahead
• When driving through steam or smoke
• When driving in a place where the sur- rounding brightness changes suddenly,
such as at the entrance or exit of a tunnel
• When a very bright light, such as the sun
or the headlights of oncoming traffic,
shines directly into the front camera
• When the surrounding area is dim, such
as at dawn or dusk, or while at night or in
a tunnel
• After the engine has started the vehicle
has not been driven for a certain amount
of time
• While making a left/r ight turn and for a
few seconds after making a left/right turn
• While driving on a curve and for a few seconds after driving on a curve
• If your vehicle is skidding
• If the front of the vehicle is raised or low- ered
• If the wheels are misaligned

The following settings can be changed.
For how to change settings, refer to P.358
“Front Cam-
era Unavail-
able”
The operation conditions
of the camera sensor (tem-
perature, etc.) are not met.
 When the operation
conditions of the camera
sensor (temperature, etc.)
are met, the LDA system
will become available. Turn
the LDA system off, wait
for a little while, and then
turn the LDA system back
on.
“Lane Depar-
ture Alert
Unavailable”
The LDA system is tempo-
rarily canceled due to a
malfunction in a sensor
other than the camera sen-
sor.
 Turn the LDA system off
and follow the appropriate
troubleshooting proce-
dures for the warning mes-
sage. Afterward, drive the
vehicle for a short time,
and then turn the LDA sys-
tem back on.
“Lane Depar-
ture Alert
Unavailable
Below
Approx
32MPH”The LDA system cannot be
used as the vehicle speed
is less than approximately
32 mph (50 km/h).
 Drive the vehicle at
approximately 32 mph
(50 km/h) or more.
“Lane Depar-
ture Alert

Driving
This mode employs a radar sensor to detect the presence of vehicles up to approx-
imately 328 ft. (100 m) ahead, determines the current vehicle-to-vehicle following
distance, and operates to maintain a suit able following distance from the vehicle
ahead.
Note that vehicle-to-vehicle distance will close in when traveling on downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle distance
can also be set by operating the ve hicle-to-vehicle distance switch.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears
When a vehicle is detected running ahead of you, the system automatically decelerates
your vehicle. When a greater reduction in vehicle speed is necessary, the system applies
the brakes (the stop lights will come on at this time). The system will respond to changes in
the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by
the driver. Approach warning warns you when th e system cannot decelerate sufficiently to
prevent your vehicle from clos ing in on the vehicle ahead.
Example of acceleration
When there are no longer any preceding vehicles driving slower than the set
speed
The system accelerates until the set speed is reached. The system then returns to constant
speed cruising.

If a vehicle is running ahead of you, the pre-
ceding vehicle mark will also be dis-
played.

1Normal mode/Custom mode
Normal mode and custom mode are
selected by pressing the driving mode
select switch. Each time the switch is
pressed, the driving mode changes
between normal mode and custom mode.
When custom mode is selected, the “CUS-
TOM” indicator will be illuminated.
When Eco drive mode or sport mode is
selected, pressing th e switch changes the
driving mode to normal mode.
•Normal mode
Provides an optimal balance of fuel econ-
omy, quietness, and dynamic performance.
Suitable for city driving.
•Custom mode
Allows you to drive with the following func-
tions set to your preferred settings.
Custom mode settings can only be
changed on the drive mode customization
display of the Center Display. ( P.208)
2Eco drive mode
Helps the driver accelerate in an
eco-friendly manner and improve fuel
economy through moderate throttle char-
acteristics and by controlling the operation
of the air conditioning system (heat-
ing/cooling).
When not in Eco drive mode, if the driving
mode select switch is turned to the left, the
Eco drive mode indicator will come on.
3Sport mode
• SPORT S mode
Controls the transmission and engine to
provide quick, powerful acceleration. Also,
gear shift timing is controlled to suit sporty
driving, making this mode is suitable for
when agile driving response is desired,
such as when driving on roads with many
curves.
When not in SPORT S mode, if the driving
mode select switch is turned to the right,
the “SPORT S” indicator will come on.
• SPORT S+ mode
Provides earlier downshift timing than
SPORT S mode in order to maintain a high
engine speed and provides faster gear
changes. This mode also changes the
steering feel, susp ension control and
VDIM control, making it suitable for pow-
erful sporty driving.
