WARNING
■Emergency steering assist (for region A) 
● As emergency steering assist operation will be canceled when the system 
determines that lane departure prevention function has been com pleted. 
● Emergency steering assist may not operate or may be cancel in the follow- 
ing cases as the system may determine the driver is taking acti ons. 
• If the accelerator pedal is being depressed strongly, the stee ring wheel 
is  being  operated  sharply,  the  brake  pedal  is  being  depressed  o r  the 
turn signal lever is being  operated. In this case, the system m ay deter- 
mine that the driver is taking evasive action and the emergency  steering 
assist may not operate. 
• In  some  situations,  while  the  emergency  steering  assist  is  ope rating, 
operation  of  the  function  may  be  canceled  if  the  accelerator  pe dal  is 
depressed strongly, the steering wheel is operated sharply or t he brake 
pedal  is  being  depressed  and  the  system  determines  that  the  dri ver  is 
taking evasive action. 
• When  the emergency  steering  assist  is  operating,  if the  steeri ng  wheel 
is  held  firmly  or  is  operated  in  the  opposite  direction  to  that   which  the 
system is generating torque, the function may be canceled. 
■ When to disable the pre-collision system 
In  the  following  situations,  disable  the  system,  as  it  may  not  operate  prop- 
erly, possibly leading to an accident resulting in death or ser ious injury: 
● When the vehicle is being towed 
● When your vehicle is towing another vehicle 
● When  transporting  the  vehicle  via  truck,  boat,  train  or  similar  means  of 
transportation 
● When the vehicle is raised on a lift with the hybrid system on and the tires 
are allowed to rotate freely 
● When inspecting  the vehicle using a  drum tester such  as a  chassis dyna- 
mometer  or  speedometer  tester,  or  when  using  an  on  vehicle  whee l  bal- 
ancer 
● When a  strong impact is  applied to  the front  bumper or front  grille, due to 
an accident or other reasons 
● If the vehicle cannot be driven in a stable manner, such as when the vehi- 
cle has been in an accident or is malfunctioning 
● When the vehicle is driven in a sporty manner or off-road 
● When the tires are not properly inflated

● Pre-collision braking 
If either of the following occur while the pre-collision brakin g function is oper- 
ating, it will be canceled: 
• The accelerator pedal is depressed strongly. 
• The steering wheel is turned sharply or abruptly. 
● Emergency steering assist (for region A) 
When the turn signal lights are flashing, emergency steering as sist will not 
operate in case of an emergency. 
If  any  of  the  following  occur  while  the  emergency  steering  assi st  function  is 
operating, it will be canceled: 
• The accelerator pedal is depressed strongly. 
• The steering wheel is turned sharply or abruptly.
• The brake pedal is depressed.

LTA (Lane Tracing Assist)
While  driving  on  a  road  with  clear  white  (yellow)  lane  lines,  the  LTA 
system  warns  the  driver  if  the  vehicle  may  deviate  from  the  cur rent 
lane  or  course*,  and  also  can  slightly  operate  the  steering  wheel  to 
help avoid deviation from the lane or course*. Also, while the dynamic 
radar cruise control with full-speed range is operating, this s ystem will 
operate the steering wheel to maintain the vehicle’s lane posit ion. 
The  LTA  system  recognizes  white 
(yellow)  lane  lines  or  a  course*
using  the  front  camera.  Addition-
ally,  it  detects  preceding  vehicles 
using the front camera and radar.

or a curb

Summary of functions
WARNING
■ Before using LTA system 
● Do  not  rely  solely  upon  the  LTA  system.  The  LTA  system  does  not  auto- 
matically  drive  the vehicle  or  reduce the  amount of  attention  t hat must be 
paid to the area in front of the  vehicle. The driver must always assume full 
responsibility for driving safely by paying careful attention t o the surround- 
ing  conditions  and  operating  the  steering  wheel  to  correct  the  path  of  the 
vehicle. Also,  the  driver  must  take  adequate  breaks  when  fatigu ed,  such 
as from driving for a long period of time. 
● Failure to perform appropriate driving operations and pay careful attention 
may lead to an accident, resulting in death or serious injury.

WARNING
■Conditions in which functions may not operate properly 
In  the  following  situations,  the  functions  may  not  operate  prop erly  and  the 
vehicle  may  depart  from  its  lane.  Drive  safely  by  always  paying   careful 
attention to your surroundings and operate the steering wheel t o correct the 
path of the vehicle without relying solely on the functions. 
● When  the  follow-up  cruising  display  is  displayed  (P.  396)  and  the  pre- 
ceding vehicle is swaying. (Your vehicle may sway accordingly a nd depart 
from the lane.) 
● When  the  follow-up  cruising  display  is  displayed  (P.  396)  and  the  pre- 
ceding vehicle departs from its lane. (Your vehicle may follow  the preced- 
ing vehicle and depart from the lane.) 
● When  the  follow-up  cruising  display  is  displayed  (P.  396)  and  the  pre- 
ceding  vehicle  is  being  driven  extremely  close  to  the  left/righ t  lane  line. 
(Your vehicle may follow the preceding vehicle and depart from  the lane.) 
● Vehicle is being driven around a sharp curve.
●When  the  follow-up  cruising  display  is 
displayed  ( P.  396)  and  the  preceding 
vehicle  changes  lanes.  (Your  vehicle 
may  follow  the  preceding  vehicle  and 
also change lanes.)
●Objects  or  patterns  that  could  be  mis- 
taken  for white  (yellow)  lines are  pres- 
ent on the side of the road (guardrails,
reflective poles, etc.).

■Lane departure alert function 
When  the  system  determines 
that  the  vehicle  might  depart 
from its lane or course*,  a 
warning  is  displayed  on  the 
multi-information  display,  and  a 
warning  buzzer  will  sound  to 
alert the driver.
When  the  warning  buzzer  sounds, 
check the area around your vehicle 
and  carefully  operate  the  steering 
wheel  to  move  the  vehicle  back  to
the center of the lane. 
Vehicle  with  BSM:  When  the  sys- 
tem  determines  that  the  vehicle
might  depart  from  its  lane  and  that 
the  possibility  of  a  collision  with  an 
overtaking  vehicle  in  the  adjacent
lane  is  high,  the  lane  departure 
alert  will  operate  even  if  the  turn 
signals are operating.
