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.
●When the system determines that the 
vehicle may deviate from the lane 
while driving around a curve while the 
lane centering function is operating.
Depending on the vehicle condition and 
road conditions, the warning may not 
operate. Also, if the system determines 
that the vehicle is driving around a 
curve, warnings will occur earlier than 
during straight-lane driving.
●When the system determines that the 
driver is driving without holding the 
steering wheel while the steering 
wheel assist of the steering assist 
function is operating.

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 normally driven, the vehi-
cle may accelerate when the turn signal lever is operated in the 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 system then returns to  
constant speed cruising.

4-5. Using the driving support systems
*: If equipped
The RSA system recognizes spe- 
cific road signs using the front cam- 
era and/or navigation system (when  
speed limit information is available)  
to provide information to the driver  
via the display. 
If the system judges that the vehicle  
is being driven over the speed limit,  
performing prohibited actions, etc.,  
according to the recognized road  
signs, it notifies the driver through a  
visual notification and notification  
buzzer. 
When the front camera recognizes  
a sign and/or information of a sign  
is available from the navigation sys- 
tem, the sign will be displayed on  
the multi-information display. 
 z When the driving support system  
information is selected, a maxi- 
mum of 3 signs can be dis- 
played. ( →P. 8 6 ) 
 z When a tab other than the driving

WARNING
■Before using the RSA 
Do not rely solely upon the RSA sys- 
tem. RSA is a system which supports  the driver by providing information, but it is not a replacement for a  
driver’s own vision and awareness.  Drive safely by always paying careful attention to the traffic rules.
