4-5. Using the driving support systems
the possibility of a frontal collision is
high, the system applies greater
braking force in relation to how
strongly the brake pedal is
depressed.
■Pre-collision braking
If the system determines that the
possibility of a frontal collision is
extremely high, the brakes are
automatically applied to help avoid
the collision or reduce the impact of
the collision.
■Emergency steering assist (for
region A)
If the system determines that the
possibility of a collision with a
pedestrian is high and that there is
sufficient space for the vehicle to be
steered into within its lane, and the
driver has begun evasive maneuver
or steering, emergency steering
assist will assist the steering move-
ments to help enhance the vehicle
stability and for lane departure pre-
vention.
■Intersection right/left turn
assistance (for region A)
If the system determines that there
is a high possibility of a collision in
the following situations, it will assist
with Pre-collision warning and, if
necessary Pre-collision braking.
Depending on the configuration of
the intersection, it may not be pos-
sible to support.
 When you turn right/left at an
intersection and cross the path of
an oncoming vehicle
 When you turn right/left, pedes-
trian is detected in the forward
direction and estimated to enter
your vehicle’s path (bicyclists are
not detected.)
WARNING
■Limitations of the pre-collision system
●The driver is solely responsible for
safe driving. Always drive safely, taking care to observe your sur-roundings.
Do not use the pre-collision system instead of normal braking opera-tions under any circumstances.
This system will not prevent colli- sions or lessen collision damage or injury in every situation. Do not
overly rely on this system. Failure to do so may lead to an accident, resulting in death or serious injury.

WARNING
●Although this system is designed to he l p a vo id a c ol li s io n o r he lp r ed u ce
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 5
• Conditions under which the system
may not operate properly: P. 1 6 7
●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.

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, d etermines 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 distanc e 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 appe ars
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 ti me). The system will
respond to changes in the speed of the vehicle ahead in order t o maintain the vehi-
cle-to-vehicle distance set by the driver. Approach warning war ns 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 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

cle-to-vehicle distance
increases/decreases in accor-
dance with vehicle speed.
1 Pressing the cancel switch can-
cels the speed control.
The speed control is also canceled
when the brake pedal is depressed.
2 Pressing the “+RES” switch
resumes the cruise control and
returns vehicle speed to the set
speed.
However, cruise control does not
resume when the vehicle speed is
approximately 25 km/h (16 mph) or
less.
When your vehicle is too close to a
vehicle ahead, and sufficient auto-
matic deceleration via the cruise
control is not possible, the display
will flash and the buzzer will sound
to alert the driver. An example of
this would be if another driver cuts
in front of you while you are follow-
ing a vehicle. Depress the brake
pedal to ensure an appropriate
vehicle-to-vehicle distance.
■Warnings may not occur when
In the following instances, warnings
may not occur even when the vehi-
cle-to-vehicle distance is small.
 When the speed of the preceding
vehicle matches or exceeds your
vehicle speed
 When the preceding vehicle is
traveling at an extremely slow
speed
 Immediately after the cruise con-
trol speed was set

■Accelerating after setting the vehi-cle speed
The vehicle can accelerate by operating the accelerator pedal. After accelerat-ing, the set speed resumes. However,
during vehicle-to-vehicle distance con- trol mode, the vehicle speed may decrease below the set speed in order
to maintain the distance to the preceding vehicle.
■Shift position selection
Select a shift position according to the
vehicle speed. If the engine speed is too high or too low, control may be automat-ically canceled.
■Automatic cancelation of vehicle-
