WARNING
●Although this system is designed to help avoid a collision or help reduce
the impact of the collision, its effec- tiveness may change according to various conditions, therefore the
system may not always be able to achieve the same level of perfor-mance.
Read the following conditions care- fully. Do not overly rely on this sys-tem and always drive carefully.
• Conditions under which the system may operate even if there is no pos-
sibility of a collision: →P. 1 6 7
• Conditions under which the system
may not operate properly: →P. 1 6 9
●Do not attempt to test the operation
of the pre-collision system yourself. Depending on the objects used for testing (dummies, cardboard
objects imitating detectable objects, etc.), the system may not operate properly, possibly leading to an
accident.
■Pre-collision braking
●When the pre-collision braking function is operating, a large amount of braking force will be
applied.
●If the vehicle is stopped by the
operation of the pre-collision brak- ing function, the pre-collision brak-ing function operation will be
canceled after approximately 2 sec- onds. Depress the brake pedal as necessary.
●The pre-collision braking function may not operate if certain opera-tions are performed by the driver. If
the accelerator pedal is being depressed strongly or the steering wheel is being turned, the system
may determine that the driver is tak- ing evasive action and possibly pre-vent the pre-collision braking
function from operating.
●In some situations, while the pre-
collision braking function is operat- ing, operation of the function may be canceled if the accelerator pedal
is depressed strongly or the steer- ing wheel is turned and the system determines that the driver is taking
evasive action.
●If the brake pedal is being
depressed, the system may deter- mine that the driver is taking eva-sive action and possibly delay the
operation timing of the pre-collision braking function.
■Emergency steering assist (for region A)
●As emergency steering assist oper-
ation will be canceled when the sys- tem determines that lane departure prevention function has been com-
pleted.
●Emergency steering assist may not
operate or may be cancel in the fol- lowing cases as the system may determine the driver is taking
actions.
• If the accelerator pedal is being
depressed strongly, the steering wheel is being operated sharply, the brake pedal is being depressed
or the turn signal lever is being operated. In this case, the system may determine that the driver is tak-
ing evasive action and the emer- gency steering assist may not operate.

●Pre-collision warning
●Pre-collision brake assist
●Pre-collision braking
If either of the following occur while the pre-collision braking function is operating, 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 assist will not operate in
case of an emergency.
If any of the following occur while the emergency steering assist function is operat-
ing, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.

■Object detection function
The system detects objects based on
their size, profile, motion, etc. However,
an object may not be detected depend-
ing on the surrounding brightness and
the motion, posture, and angle of the
detected object, preventing the system
from operating properly. (→P.169)

detectable objects.

■Lane departure alert function
When the system determines that
the vehicle might depart from its
lane or course*, a warning is dis-
played on the multi-information dis-
play, 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 system
determines that the vehicle might
depart from its lane and that the possi-
bility 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.
*: Boundary between asphalt and the
side of the road, such as grass, soil,
or a curb
■Steering assist function
When the system determines that
the vehicle might depart from its
lane or course*, the system pro-
vides assistance as necessary by
operating the steering wheel in
small amounts for a short period of
time to keep the vehicle in its lane.
Vehicle with BSM: When the system
determines that the vehicle might
depart from its lane and that the possi-
bility of a collision with an overtaking
vehicle in the adjacent lane is high, the
steering assist function will operate
even if the turn signals are operating.

4-5. Using the driving support systems
This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, determines the current vehicle-to-vehicle fol-
lowing distance, and operates to maintain a suitable following distance from
the vehicle ahead. The desired vehicle-to-vehicle distance can also be set
by operating the vehicle-to-vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may become
shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
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 deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the sys-
tem 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 vehi-
cle-to-vehicle distance set by the driver. Approach warning warns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the turn signal lever is operated and your vehicle moves to an overtaking lane
while driving at 80 km/h (50 mph) or more, the vehicle will accelerate to help to over-
take a passing vehicle.
The system’s identification of what is an overtaking lane may be determined solely
based on the location of the steering wheel in the vehicle (left 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 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.
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.188)
“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.
The vehicle speed at the moment the switch is released becomes the set speed.
■Adjusting the set speed by the
