4-5. Using the driving support systems

WARNING

●

Assisting the driver to operate the vehicle
The dynamic radar cruise control has limited capability 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  control  of  the  vehicle
and act appropriately in order to ensure the safety of all involved.

■

Situations unsuitable for dynamic radar cruise control

Do not use dynamic radar cruise control 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
front camera

●

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

●

When your vehicle is towing a trailer or during emergency towing

●

When an approach warning buzzer is heard often

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 down-
hill slopes.

Driving in vehicle-to-vehicle distance control mode

4-5. Using the driving support systems

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.

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.

Pulling  the  lever  toward  you
cancels the speed control.

Vehicle-to-vehicle  distance  control
mode:  The  speed  control  is  also
canceled  when  the  brake  pedal  is
depressed.
Constant speed control mode: The
speed  setting  is  also  canceled
when the brakes are applied or the
clutch  pedal  (manual  transmission
only) is depressed.

Pushing the lever up 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 mph (40 km/h) or less.

When your vehicle is too close to
a  vehicle  ahead,  and  sufficient
automatic  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 following 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
vehicle-to-vehicle distance is small.

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 can be set when

●

Vehicles with an automatic transmission: The shift lever is in D or range 4 or
higher of S has been selected.

●

Vehicle speed is at or above 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.

■

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).

●

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.

●

4WD models: The operation cannot be switched for 5 seconds or more after
operating the front-wheel drive control switch.

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.

Automatic cancelation of constant speed control mode

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).

●

4WD models: The operation cannot be switched for 5 seconds or more after
operating the front-wheel drive control switch.

If constant speed control mode is automatically canceled for any other rea-
son, there may be a malfunction in the system. Contact your Toyota dealer.

■

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

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
approach warning (
