tem Unavailable” is displayed.

Situation

Actions

When the area around a sensor is covered 
with dirt, moisture (fogged up, covered with 
condensation, ice, etc.), or other foreign 
matter

To clean the part of the windshield in front of 
the front camera , use the windshield wipers 
or the windshield defogger of the air condi-
tioning system (



P.215).

When the temperature around the front 
camera is outside of the operational range, 
such as when the vehicle is in the sun or in an 
extremely cold environment

If the front camera is hot, such as after the 
vehicle had been parked in the sun, use the 
air conditioning system to decrease the tem-
perature around the front camera.
If a sunshade was used when the vehicle 
was parked, depending on its type, the sun-
light reflected from the surface of the sun-
shade may cause the temperature of the 
front camera to become excessively high.

If the front camera is cold, such after the 
vehicle is parked in an extremely cold envi-
ronment, use the air conditioning system to 
increase the temperature around the front 
camera.

The area in front of the front camera is 
obstructed, such as when the hood is open 
or a sticker is attached to the part of the 
windshield in front of the front camera.

Close the hood, remove the sticker, etc. to 
clear the obstruction.

When “Pre-Collision System Unavailable” is 
displayed

Check whether there is attached materials 
on the radar sensor and radar sensor cover, 
and if there is, remove it.

■

Pre-collision warning

When the system determines that the 
possibility of a frontal collision is high, a 
buzzer will sound and a warning mes-
sage will be displayed on the 
multi-information display to urge the 
driver to take evasive action.

■

Pre-collision brake assist

When the system determines that 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

When the system determines that the 
possibility of a frontal collision is high, 
the system warns the driver. If the sys-
tem determines that the possibility of a 
frontal collision is extremely high, the 
brakes are automatically applied to 
help avoid the collision or reduce the 
collision speed.

■

Suspension control (if equipped)

When the system determines that the 
possibility of a frontal collision is high, 
the Adaptive Variable Suspension Sys-
tem (



P.199) will control the damping 

force of the shock absorbers to help 
maintain an appropriate vehicle pos-
ture.

PCS (Pre-Collision System)

The pre-collision system uses a 
radar sensor and front camera to 
detect vehicles and pedestrians in 
front of your vehicle. When the sys-
tem determines that the possibility 
of a frontal collision with a vehicle 
or pedestrian is high, a warning 
operates to urge the driver to take 
evasive action and the potential 
brake pressure is increased to help 
the driver avoid the collision. If the 
system determines that the possi-
bility of a frontal collision with a 
vehicle or pedestrian is extremely 
high, the brakes are automatically 
applied to help avoid the collision or 
help reduce the impact of the colli-
sion.

The pre-collision system can be dis-
abled/enabled and the warning tim-
ing can be changed. (

WARNING

■

Limitations of the pre-collision system

●

The driver is solely responsible for safe 

driving. Always drive safely, taking 

care to observe your surroundings.

Do not use the pre-collision system 

instead of normal braking operations 

under any circumstances. This system 

will not prevent collisions or lessen col-

lision damage or injury in every situa-

tion. Do not overly rely on this system. 

Failure to do so may lead to an acci-

dent, resulting in death or serious 

injury.

●

Although this system is designed to 

help avoid a collision or help reduce 

the impact of the collision, its effective-

ness may change according to various 

conditions, therefore the system may 

not always be able to achieve the same 

level of performance.

Read the following conditions care-

fully. Do not overly rely on this system 

and always drive carefully.

• Conditions under which the system 

may operate even if there is no possi-

bility of a collision: 



P.160

• Conditions under which the system 

may not operate properly: 



P.162

●

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, pos-

sibly leading to an accident.

■

Pre-collision braking

●

When the pre-collision braking func-

tion is operating, a large amount of 

braking force will be applied.

●

If the vehicle is stopped by the opera-

tion of the pre-collision braking func-

tion, the pre-collision braking function 

operation will be canceled after 

approximately 2 seconds. Depress the 

brake pedal as necessary.

●

The pre-collision braking function may 

not operate if certain operations are 

performed by the driver. If the acceler-

ator pedal is being depressed strongly 

or the steering wheel is being turned, 

the system may determine that the 

driver is taking evasive action and pos-

sibly prevent the pre-collision braking 

function from operating.

●

In some situations, while the pre-colli-

sion braking function is operating, 

operation of the function may be can-

celed if the accelerator pedal is 

depressed strongly or the steering 

wheel is turned and the system deter-

mines that the driver is taking evasive 

action.

●

If the brake pedal is being depressed, 

the system may determine that the 

driver is taking evasive action and pos-

sibly delay the operation timing of the 

pre-collision braking function.

■

When to disable the pre-collision sys-

tem

In the following situations, disable the 

system, as it may not operate properly, 

possibly leading to an accident resulting 

in death or serious 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 engine running 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 wheel bal-

ancer

●

When a strong impact is applied to the 

front bumper or front grille, due to an 

accident or other reasons

frontal collision with a vehicle or pedestrian 

is high.
Each function is operational at the following 

speeds:

●

Pre-collision warning:

• Vehicle speed is between approximately 

7 and 110 mph (10 and 180 km/h). (For 

detecting a pedestrian, vehicle speed is 

between approximately 7 and 50 mph 

[10 and 80 km/h].)

• The relative speed between your vehicle 

and the vehicle or pedestrian ahead is 

approximately 7 mph (10 km/h) or more.

●

Pre-collision brake assist:

• Vehicle speed is between approximately 

20 and 110 mph (30 and 180 km/h). (For 

detecting a pedestrian, vehicle speed is 

between approximately 20 and 50 mph 

[30 and 80 km/h].)

• The relative speed between your vehicle 

and the vehicle or pedestrian ahead is 

approximately 20 mph (30 km/h) or 

more.

Pre-collision braking:

• Vehicle speed is between approximately 

7 and 110 mph (10 and 180 km/h). (For 

detecting a pedestrian, vehicle speed is 

between approximately 7 and 50 mph 

[10 and 80 km/h].)

• The relative speed between your vehicle 

and the vehicle or pedestrian ahead is 

approximately 7 mph (10 km/h) or more.

The system may not operate in the following 

situations:

●

If a battery terminal has been discon-

nected and reconnected and then the 

vehicle has not been driven for a certain 

amount of time

●

If the shift lever is in R

●

If VSC is disabled (only the pre-collision 

warning function will be operational)

■

Pedestrian detection function

The pre-collision system detects pedestri-

ans based on the size, profile, and motion of 

a detected object. However, a pedestrian 

may not be detected depending on the sur-

rounding brightness and the motion, pos-

ture, and angle of the detected object, 

preventing the system from operating prop-

erly. (



P.162)

■

Cancelation of the 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.

■

Conditions under which the system may

Lane departure alert function

When the system determines that the 
vehicle might depart from its lane, a 
warning is displayed on the multi-infor-
mation display, and either the warning 
buzzer sounds or the steering wheel 
vibrates to alert the driver.

When the warning buzzer sounds or the 
steering wheel vibrates, check the sur-
rounding road situation and carefully oper-
ate the steering wheel to move the vehicle 
back to the center of the lane.

■

Steering control function

When the system determines that the 
vehicle might depart from its lane, the 
system provides assistance as neces-
sary by operating the steering wheel in 
small amounts for a short period of 
time to keep the vehicle in its lane.

If the system detects that the steering 
wheel has not been operated for a fixed 
amount of time or the steering wheel is not 
being firmly gripped, a warning is displayed 
on the multi-information display and the 
function is temporarily canceled.

LDA (Lane Departure Alert 
with steering control)

When driving on highways and 
freeways with white (yellow) lines, 
this function alerts the driver when 
the vehicle might depart from its 
lane and provides assistance by 
operating the steering wheel to 
keep the vehicle in its lane.

The LDA system recognizes visible 
white (yellow) lines with the camera 
sensor on the upper portion of the 
front windshield.

WARNING

■

Before using LDA system

Do not rely solely upon the LDA system. 

The LDA system does not automatically 

drive the vehicle or reduce the amount of 

attention that must be paid to the area in 

front of the vehicle. The driver must 

always assume full responsibility for driv-

ing safely by paying careful attention to 

the surrounding conditions and operat-

ing the steering wheel to correct the path 

of the vehicle. Also, the driver must take 

adequate breaks when fatigued, 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.

■

To avoid operating LDA system by 

mistake

When not using the LDA system, use the 

LDA switch to turn the system off.

■

Situations unsuitable for LDA system

Do not use the LDA system in the follow-

ing situations.

The system may not operate properly 

and lead to an accident, resulting in 

death or serious injury.

●

A spare tire, tire chains, etc. are 

equipped.

●

When the tires have been excessively 

worn, or when the tire inflation pres-

sure is low.

●

Tires which differ by structure, manu-

facturer, brand or tread pattern are 

used.

●

Objects or patterns that could be mis-

taken for white (yellow) lines are pres-

ent on the side of the road (guardrails, 

curbs, reflective poles, etc.).

●

Vehicle is driven on a snow-covered 

road.
