Daytime running light system

●

The daytime running lights illuminate using the same lights as the parking

lights and illuminate brighter than the parking lights.

●

To make your vehicle more visible to other drivers during daytime driving,

the  daytime  running  lights  turn  on  automatically  when  all  of  the  following

conditions are met. (The daytime running lights are not designed for use at

night.)
• The engine is running
• The parking brake is released
• The headlight switch is in the 

 or “AUTO”

*

 position

*

: When the surroundings are bright

The daytime running lights remain on after they illuminate, even if the parking
brake is set again.

●

For  the  U.S.A.:  Daytime  running  lights  can  be  turned  off  by  operating  the

switch.

●

Compared  to  turning  on  the  headlights,  the  daytime  running  light  system

offers greater durability and consumes less electricity, so it can help improve

fuel economy.

■

Headlight control sensor

The sensor may not function properly if an

object is placed on the sensor, or anything

that  blocks  the  sensor  is  affixed  to  the

windshield. 

Doing  so  interferes  with  the  sensor

detecting  the  level  of  ambient  light  and

may  cause  the  automatic  headlight  sys-

tem to malfunction.

WARNING

■

When refueling the vehicle

Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.

●

After  exiting  the  vehicle  and  before  opening  the  fuel  door,  touch  an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.

●

Always hold the grips on the fuel tank cap and turn it slowly to remove it. 
A  whooshing  sound  may  be  heard  when  the  fuel  tank  cap  is  loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out the filler neck and cause injury.

●

Do  not  allow  anyone  that  has  not  discharged  static  electricity  from  their
body to come close to an open fuel tank.

●

Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.

●

Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.

●

Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.

■

When refueling

Observe the following precautions to prevent fuel overflowing from the fuel
tank:

●

Securely insert the fuel nozzle into the fuel filler neck.

●

Stop filling the tank after the fuel nozzle automatically clicks off.

●

Do not top off the fuel tank.

NOTICE

■

Refueling

Do not spill fuel during refueling. 
Doing  so  may  damage  the  vehicle,  such  as  causing  the  emission  control
system to operate abnormally, or damaging fuel system components, or the
vehicle’s painted surface.

PCS (Pre-Collision System)

The pre-collision system uses a radar sensor and camera sen-
sor to detect vehicles and pedestrians in front of your vehicle.
When the system determines that the possibility of a frontal col-
lision 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 possibility of a frontal collision with
a  vehicle  or  pedestrian  is  extremely  high,  the  brakes  are  auto-
matically applied to help avoid the collision or help reduce the
impact of the collision.

The pre-collision system can be disabled/enabled and the warning
timing can be changed. (

◆

Pre-collision brake assist

When  the  system  determines  that  the  possibility  of  a  frontal  colli-

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
collision damage or injury in every situation. Do not overly rely on this sys-
tem. Failure to do so may lead to an accident, 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 effectiveness may change according to vari-
ous conditions, therefore the system may not always be able to achieve
the same level of performance. 
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no pos-

sibility of a collision: 



P. 235

• Conditions under which the system may not operate properly: 



P. 238

●

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 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  accelerator  pedal  is  being  depressed
strongly or the steering wheel is being turned, the system may determine
that the driver is taking evasive action and possibly prevent the pre-colli-
sion braking function from operating.

●

In  some  situations,  while  the  pre-collision  braking  function  is  operating,
operation  of  the  function  may  be  canceled  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 possibly delay the operation timing of
the pre-collision braking function.

sibility of a 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 approx-
imately 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.

there is a possibility of a frontal collision and operate.
• When passing a vehicle or pedestrian
• When changing lanes while overtaking a preceding vehicle
• When overtaking a preceding vehicle that is changing lanes

The pre-collision system detects pedestri-
ans based on the size, profile, and motion
of  a  detected  object.  However,  a  pedes-
trian  may  not  be  detected  depending  on
the  surrounding  brightness  and  the
motion,  posture,  and  angle  of  the
detected  object,  preventing  the  system
from operating properly. (

that  the  vehicle  might  depart
from  its  lane,  the  system  pro-
vides  assistance  as  necessary
by operating the steering wheel
in  small  amounts  for  a  short
period of time to keep the vehi-
cle 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-infor-
mation  display  and  the  warning
buzzer sounds.

WARNING

■

Before using LDA system

Do not rely solely upon the LDA system. The LDA system does not auto-
matically 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 driving safely by paying careful attention to the surround-
ing  conditions and operating 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.

WARNING

■

Before using dynamic radar cruise control with full-speed range

●

Driving safely is the sole responsibility of the driver. Do not rely solely on
the system, and drive safely by always paying careful attention to your sur-
roundings.

●

The  dynamic  radar  cruise  control  with  full-speed  range  provides  driving
assistance to reduce the driver’s burden. However, there are limitations to
the assistance provided.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be correctly detecting the vehicle ahead: 



P. 264

• Conditions  under  which  the  vehicle-to-vehicle  distance  control  mode

may not function correctly: 



P. 266

●

Set the speed appropriately depending on the speed limit, traffic flow, road
conditions, weather conditions, etc. The driver is responsible for checking
the set speed.

●

Even when the system is functioning normally, the condition of the preced-
ing  vehicle  as  detected  by  the  system  may  differ  from  the  condition
observed  by  the  driver.  Therefore,  the  driver  must  always  remain  alert,
assess the danger of each situation and drive safely. Relying on this sys-
tem or assuming the system ensures safety while driving can lead to an
accident, resulting in death or serious injury.

●

Switch the dynamic radar cruise control with full-speed range off using the
“ON-OFF” button when not in use.

■

Cautions regarding the driving assist systems

Observe the following precautions, as there are limitations to the assistance
provided by the system.
Failure to do so may cause an accident resulting in death or serious injury.

●

Assisting the driver to measure following distance
The dynamic radar cruise control with full-speed range is only intended to
help the driver in determining the following distance between the driver’s
own vehicle and a designated vehicle traveling ahead. It is not a mecha-
nism that allows careless or inattentive driving, and it is not a system that
can  assist  the  driver  in  low-visibility  conditions.  It  is  still  necessary  for
driver to pay close attention to the vehicle’s surroundings.

●

Assisting the driver to judge proper following distance
The  dynamic  radar  cruise  control  with  full-speed  range  determines
whether  the  following  distance  between  the  driver’s  own  vehicle  and  a
designated vehicle traveling ahead is within a set range. It is not capable
of making any other type of judgement. Therefore, it is absolutely neces-
sary for the driver to remain vigilant and to determine whether or not there
is a possibility of danger in any given situation.

254

4-5. Using the driving support systems

WARNING

●

Assisting the driver to operate the vehicle
The dynamic radar cruise control with full-speed range has limited capabil-
ity to prevent or avoid a collision with a vehicle traveling ahead. Therefore,
if there is ever any danger, the driver must take immediate and direct con-
trol of the vehicle and act appropriately in order to ensure the safety of all
involved.

■

Situations unsuitable for dynamic radar cruise control with full-speed
range

Do not use dynamic radar cruise control with full-speed range in any of the
following situations.
Doing so may result in inappropriate speed control and could cause an acci-
dent resulting in death or serious injury.

●

Roads where there are pedestrians, cyclists, etc.

●

In heavy traffic

●

On roads with sharp bends

●

On winding roads

●

On slippery roads, such as those covered with rain, ice or snow

●

On steep downhills, or where there are sudden changes between sharp up
and down gradients 
Vehicle speed may exceed the set speed when driving down a steep hill.

●

At entrances to freeways and highways

●

When weather conditions are bad enough that they may prevent the sen-
sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)

●

When there is rain, snow, etc., on the front surface of the radar sensor or
camera sensor

●

In traffic conditions that require frequent repeated acceleration and decel-
eration

●

This mode employs a radar sensor to detect the presence of vehicles
up  to  approximately  328  ft.  (100  m)  ahead,  determines  the  current
vehicle-to-vehicle following distance, and operates to maintain a suit-
able following distance from the vehicle ahead.

Note  that  vehicle-to-vehicle  distance  will  close  in  when  traveling  on  long

C-HR_OM_USA_OM10634U

Example of constant speed cruising
When there are no vehicles ahead

The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle  distance  can  also  be  set  by  operating  the  vehicle-to-vehicle  dis-
tance switch.

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
decelerates  your  vehicle.  When  a  greater  reduction  in  vehicle  speed  is
necessary, the system 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 vehicle-to-vehicle distance set by the driver.
Approach  warning  warns  you  when  the  system  cannot  decelerate  suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pushing the
cruise control lever up or depressing the accelerator pedal will resume fol-
low-up cruising.

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.

When constant speed control mode is selected, your vehicle will main-
tain  a  set  speed  without  controlling  the  vehicle-to-vehicle  distance.
Select this mode only when vehicle-to-vehicle distance control mode
does not function correctly due to a dirty radar sensor, etc.

With  the  cruise  control  off,
press  and  hold  the  “ON-OFF”
button for 1.5 seconds or more.

Immediately  after  the  “ON-OFF”
button is pressed, the radar cruise
control  indicator  will  come  on.
Afterwards, it switches to the cruise
control indicator.
Switching  to  constant  speed  con-
trol  mode  is  only  possible  when
operating  the  lever  with  the  cruise
control off.

Accelerate  or  decelerate,  with
accelerator  pedal  operation,  to
the desired vehicle speed (at or
above  approximately  25  mph
[40  km/h])  and  push  the  lever
down to set the speed.

Dynamic radar cruise control with full-speed range can be set when

●

The shift lever is in D.

●

Vehicle speed is at or above approximately 30 mph (50 km/h).
However,  when a  preceding  vehicle is detected, the  dynamic  radar  cruise
control with full-speed range can be set even if the vehicle speed is below
approximately 30 mph (50 km/h).

■

Accelerating after setting the vehicle speed

The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating,  the  set  speed  resumes.  However,  during  vehicle-to-vehicle  distance
control mode, the vehicle speed may decrease below the set speed in order
to maintain the distance to the preceding vehicle.

■

When the vehicle stops while follow-up cruising

●

Pushing  the  lever  up  while  the  vehicle  ahead  stops  will  resume  follow-up
cruising if the vehicle ahead starts off within approximately 3 seconds after
the lever is pushed up.

●

If the vehicle ahead starts off within 3 seconds after your vehicle stops, fol-
low-up cruising will be resumed.

■

Automatic cancelation of vehicle-to-vehicle distance control mode

Vehicle-to-vehicle distance control mode is automatically canceled in the fol-
lowing situations:

●

Actual vehicle speed falls at or below approximately 25 mph (40 km/h) when
there are no vehicles ahead.

●

The preceding vehicle leaves the lane when your vehicle is following at a
vehicle speed at or below approximately 25 mph (40 km/h). Otherwise, the
sensor cannot properly detect the vehicle.

●

VSC is activated.

●

TRAC is activated for a period of time.

●

When the VSC or TRAC system is turned off.

●

The sensor cannot detect correctly because it is covered in some way.

●

Pre-collision braking is activated.

●

The parking brake is operated.

●

The vehicle is stopped by system control on a steep incline.

●

The following are detected when the vehicle has been stopped by system
control:
• The driver is not wearing a seat belt.
• The driver’s door is opened.
• The vehicle has been stopped for about 3 minutes.

If vehicle-to-vehicle distance control mode is automatically canceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.

Constant speed control mode is automatically canceled in the following situa-
tions:

●

Actual vehicle speed is more than approximately 10 mph (16 km/h) below
the set vehicle speed.

●

Actual vehicle speed falls below approximately 25 mph (40 km/h).

Brake system operation sound

If the brakes are applied automatically while the vehicle is in vehicle-to-vehi-
cle  distance  control  mode,  a  brake  system  operation  sound  may  be  heard.
This does not indicate a malfunction.

■

Warning  messages  and  buzzers  for  dynamic  radar  cruise  control  with
full-speed range

Warning messages and buzzers are used to indicate a system malfunction or
to inform the driver of the need for caution while driving. If a warning message
is shown on the multi-information display, read the message and follow the
instructions.

When the sensor may not be correctly detecting the vehicle ahead

In  the  case  of  the  following  and  depending  on  the  conditions,  operate  the
brake  pedal  when  deceleration  of  the  system  is  insufficient  or  operate  the
accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types of vehicles, the
