cle-to-vehicle distance control mode. • Width of traffic lane is approximately 3 to 4 m (10 to 13 ft.).
• Turn signal lever is not operated. • Vehicle is not being driven around a sharp curve.
• No system malfunctions are detected. ( P.251) • Vehicle does not accelerate or decel-
erate by a fixed amount or more. • Steering wheel is not operated with a steering force level suitable for chang-
ing lanes. • ABS, VSC, TRC and PCS are not operating.
• TRC or VSC is not turned off. • Hands off steering wheel warning is not displayed. ( P.250)
• The vehicle is being driven in the center of a lane.• Steering assist function is not operat-
ing.
■Temporary cancelation of functions
●When operation conditions are no lon-
ger met, a function may be temporar- ily canceled. However, when the operation conditions are met again,
operation of the function is automati- cally restored. ( P.249)
●If the operation conditions (P.249) are no longer met while the lane cen-tering function is operating, the steer-
ing wheel may vibrate and the buzzer may sound to indicate that the func-tion has been temporarily canceled.
However, if the steering wheel vibra- tion customization setting is set to on, the system will notify the driver by
vibrating the steering wheel instead of sounding the buzzer.
■Steering assist function/lane cen-tering 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 steering control of the function is overridden by the driver’s steering
wheel operation.
●Do not attempt to test the operation of the steering assist function.
■Lane departure alert function
●The warning buzzer may be difficult to hear due to external noise, audio play-
back, etc. Also, it may be difficult to feel steering wheel vibrations due to the road conditions, etc.
●Vehicle with BSM: It may not be possi-ble for the system to determine if there
is a danger of a collision with a vehicle in an adjacent lane.
●Do not attempt to test the operation of the lane departure alert function.
■Hands off steering wheel warning
In the following situations, a warning
message urging the driver to hold the steering wheel and the symbol shown in the illustration are displayed on the
multi-information display to warn the driver. The warning stops when the sys-tem determines that the driver holds the
steering wheel. Always keep your hands on the steering wheel when using this system, regardless of warnings.
●When the system determines that the driver is driving without holding the
steering wheel while the system is operating
If the driver continues to keep their
hands off of the steering wheel, the
buzzer sounds, the driver is warned and
the function is temporarily canceled.
This warning also operates in the same
way when the driver continuously oper-
ates the steering wheel only a small
amount.

4-5. Using the driving support systems
When the turn signal lever is operated and your vehicle moves t o an overtaking lane
while driving at 80 km/h (50 mph) or more, the vehicle will acc elerate to help to over-
take a passing vehicle.
The system’s identification of what is an overtaking lane may b e determined solely
based on the location of the steering wheel in the vehicle (lef t side driver position
versus right side driver position.) If the vehicle is driven to a region where the over-
taking lane is on a different side from where the vehicle is no rmally driven, the vehi-
cle may accelerate when the turn signal lever is operated in th e opposite direction to
the overtaking lane (e.g., if the driver normally operates the vehicle in a region
where the overtaking lane is to the right but then drives to a region where the over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).
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 syst em then returns to
constant speed cruising.
1 Press the cruise control main
switch to activate the cruise con-
trol.
Dynamic radar cruise control indicator will come on and a message will be dis-played on the multi-information display.
Press the switch again to deactivate the cruise control.
If the cruise control main switch is
pressed and held for 1.5 seconds or more, the system turns on in constant
speed control mode. ( P.259)
“Radar Ready”
2 Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 30 km/h
[20 mph]) and press the “-SET”
switch to set the speed.
Cruise control “SET” indicator will come on.

*3: If the turn signal indicator is not
operated when changing lanes, the
mark does not display.
In the following situations, the RSA
system will notify the driver.
When the vehicle speed exceeds
the speed notification threshold
of the speed limit sign displayed,
the sign display will be empha-
sized and a buzzer will sound.
When the RSA system recog-
nizes a no-entry sign and detects
that the vehicle has entered a
no-entry area based on the map
information of the navigation sys-
tem, the no-entry sign flashes
and a buzzer will sound. (For
vehicles with 7-inch/8-inch dis-
play navigation system)
If it is detected that your vehicle
is overtaking when a no overtak-
ing sign is displayed on the multi-
information display, the dis-
played sign will flash and a
buzzer will sound.
Depending on the situation, traffic
environment (traffic direction,
speed unit) may be detected incor-
rectly and a notification function
may not operate properly.

■Conditions in which the function may not operate or detect correctly
In the following situations, RSA does not
operate normally and may not recognize signs, display the incorrect sign, etc. However, this does not indicate a mal-
function.
●The front camera is misaligned due to
a strong impact being applied to the sensor, etc.
●Dirt, snow, stickers, etc., are on the windshield near the front camera.
●In inclement weather such as heavy rain, fog, snow or sand storms.
