Turns the brake hold system on
The brake hold standby indicator
(green) comes on. While the system is
holding the brake, the brake hold
operated indicator (yellow) comes on.
■Brake hold system operating conditions
The brake hold system cannot be turned on in the following conditions:
●The trunk or hood is not closed.
●The driver’s door is not closed.
●The driver is not wearing the seat belt.
If any of the conditions above are detected when the brake hold system is enabled,
the system will turn off and the brake hold standby indicator light will go off. In addi-
tion, if any of the conditions are detected while the system is holding the brake, a
warning buzzer will sound and a message will be shown on the multi-information dis-
play. The parking brake will then be set automatically.
■Brake hold function
●If the brake pedal is left released for a period of about 3 minutes after the system
has started holding the brake, the parking brake will be set automatically. In this
case, a warning buzzer sounds and a message is shown on the multi-information
display.
●To turn the system off while the system is holding the brake, firmly depress the
brake pedal and press the switch again.
●The brake hold function may not hold the vehicle when the vehicle is on a steep
incline. In this situation, it may be necessary for the driver to apply the brakes. The
multi-information display will inform the driver of this situation.
Brake Hold
The brake hold system keeps the brake applied when the shift lever is in
D, S or N with the system on and the brake pedal has been depressed to
stop the vehicle. The system releases the brake when the accelerator
pedal is depressed with the shift lever in D or S to allow smooth start off.

Lane departure warning function
If the system judges that the vehicle may deviate from its lane, it alerts
the driver using rapid beeping, indications on the multi-information dis-
play, and a sensory warning* given via the steering wheel.
*: A slight steering torque is applied for a short period of time in the direction of the
center of the lane.
Lane keeping assist function
• This function will be active when the vehicle-to-vehicle distance con-
trol mode of the dynamic radar crui se control with full-speed range
( P. 307) is set with vehicle speed above approximately 72 km/h
(45 mph) and while the lane departure warning function is active.
• When the lane keeping assist function is active, a slight steering
torque will be applied, to help th e driver maintain the vehicle inside
the lane.
The lane keeping assist function will be temporarily canceled if the steering
wheel is not operated, or if you continue driving with your hands lightly touch-
ing the steering wheel. ( P. 329)

●The turn signal lever is operated.
●The vehicle speed deviates from the operating range of the LKA system functions.
(The buzzer will beep twice when the lane keeping assist function is being
canceled.)
●When the lane lines cannot be recognized while driving. (The buzzer will beep
twice when the lane keeping assist function is being canceled.)
●When the wiper switch is in the high spee d position or is set to “AUTO” mode with
the wipers operating at high speed. (The lane keeping assist function will be tempo-
rarily canceled, but the lane departure warning function will continue.)

after it has been activated, even if the vehicle leaves the lane again.
■The lane departure warning
It may be difficult to feel the sensory warning depending on the road conditions.
■No-handed driving warning
If the steering wheel is not operated for approximately 15 seconds on a straight road
or approximately 5 seconds on a curve, the buzzer will beep twice, indicators on the
multi-information display will flash, and the lane keeping assist function will be tem-
porarily canceled. If you drive the vehicle with your hands lightly touching the steer-

■After the vehicle has been parked in the sun
The LKA system functions may not be available and a warning message ( P. 563)
will be displayed for a while after driving has started. In such cases, turn the LKA sys-
tem off and turn it on again after normal temperature returns. When the temperature
in the cabin decreases and the temperature around the camera sensor ( P. 324)
becomes suitable for its operation, the functions will begin to operate.
■If there are lane markers on only one side of the vehicle
The lane keeping assist function will not operate. Also, the lane departure warning
will not operate for the side on which lane markers could not be recognized.
■Conditions in which the function may not operate correctly
In the following conditions, the LKA system functions may not operate, or it may not
be possible to ensure adequate performance. Also, the camera sensor may be
unable to recognize lane lines causing the lane departure warning function to oper-
ate incorrectly, or the lane keeping assist function may not operate properly. How-
ever, this does not indicate a malfunction.
●When driving through an area with no lane markers, such as a tollbooth, a crossing
or before a ticket checkpoint
●When driving on a sharp curve
●When lanes are extremely narrow or extremely wide
●When the vehicle leans to one side an unusual amount due to a heavy load or
improper tire inflation pressure
●When the following distance between your vehicle and the vehicle ahead is
extremely short
●When the lane markers are yellow (These may be more difficult for the system to
recognize compared to white markers.)
●When the lane markers are broken, “Raised pavement marker” or stones
●When lane markers are obscured or partially obscured by sand, dirt, etc.
●When there are shadows on the road running parallel with lane markers, or if a
shadow covers the lane markers
●When driving on a particularly bright road surface, such as concrete

●When driving on a road surface that is wet due to rain, previous rainfall, standing
water, etc.
●When the vehicle experiences strong up-and-down motion such as when driving
on an extremely rough road or on a seam in the pavement
●When headlight brightness at nighttime is reduced due to dirt on the lenses, or
when the headlights are misaligned
●When driving with a strong crosswind
●When driving on winding roads or roads that are uneven
●When driving on rough or unpaved roads
■When changing the tires
Depending on the tires used, such as snow tires, etc., sufficient performance may not
be maintainable.
■Warning messages for LKA
Warning messages are used to indicate a system malfunction or to inform the driver
of the need for caution while driving. ( P. 563)
CAUTION
■Before using the LKA system
Do not rely solely on the LKA system. The LKA system does not drive the vehicle
automatically, nor does it reduce the amount of care you need to take. As such, the
driver must always assume full responsibility for understanding his/her
surroundings, for operating the steering wheel to correct the driving line, and for
driving safely.
Inappropriate or negligent driving could lead to an accident.
■To avoid operating the LKA by mistake
Switch the LKA off using the LKA switch when not in use.
