This mode employs a radar sensor to detect the presence of vehicles up to
approximately 100 m (328 ft.) ahead, determines the current vehicle-to-vehicle
following distance, and operates to maintain a suitable following distance from
the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long downhill slopes.
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 dis- tance can also be set by operating the vehicle-to-vehicle distance button.
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 reductio n 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 wa rning warns you when the system cannot decelerate sufficiently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your ve hicle will also stop (vehicle is stopped by system control). After the vehicle ahead starts off, pushing the cruise control lever upor depressing the accelerator peda l will resume follow-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 con-
stant speed cruising.

Pressing the button changes the vehi-
cle-to-vehicle distance as follows:
Long
Medium
Short
The vehicle-to-vehicle distance is set automatically to long mode when theengine switch is turned to IGNITION
ON mode.
If a vehicle is running ahead of you, the preceding vehicle mark will also be displayed.
Select a distance from the table below. Note that the distances shown corre-
spond to a vehicle speed of 80 km/h (50 mph). Vehicle-to-vehicle distance
increases/decreases in accordance with vehicle speed. When the vehicle is
stopped by system control, the vehicle- to-vehicle distance will be about 3 m
(10 ft.) to 5 m (16 ft.) regardless of the vehicle-to-vehicle distance setting.
After the vehicle ahead of you starts off,
push the lever up.
Your vehicle will also resume follow-up
cruising if the accelerator pedal is
depressed after the vehicle ahead of
you starts off.

◆When the brake hold system is enabled
The Stop & Start system is operational when the brake hold system is operat-
ing. (P. 263)
■Stopping the engine
While driving with the shift lever in D
or M, depress the brake pedal, and
stop the vehicle.
The Stop & Start indicator will come
on.
While the brake hold system is oper- ating, the brake hold operated indi-
cator (yellow) will come on. If the brake pedal is released, the enginewill remain stopped by the Stop &
Start system.
■Restarting the engine
Depress the accelerator pedal. (Releasing the brake pedal will not restart the
engine.)
The Stop & Start indicator and brake hold op erated indicator (yellow) will turn off.
■Stop & Start system operation when the brake hold system is operating
●If the engine is restarted automatically by the Stop & Start system when the
brake hold system is operating, the brake hold system will continue to apply
the brakes.
●If the operation conditions of the brake hold system are no longer met ( P.
263) while the engine is stopped by the Stop & Start system, the brake hold
system will stop operating.
At this time, the parking brake will be a pplied automatically and the engine will be restarted automatically.

◆When the dynamic radar cruise control with full-speed range is operating
(if equipped)
The Stop & Start system is operational during a controlled stop by the
dynamic radar cruise control with full-speed range. (P. 332)
■Stopping the engine
While driving with the dynamic
radar cruise control with full-speed
range in vehicle-to-vehicle distance
control mode, the engine will stop
automatically if the vehicle comes to
a complete stop through a con-
trolled stop. (The engine will stop
automatically even though the brake
pedal is not depressed.)
The Stop & Start indicator will come on.
■Restarting the engine
When the preceding vehicle starts off, the engine will restart automatically.
The Stop & Start indicator will turn off.
■Stop & Start system operation during a controlled stop by the dynamic
radar cruise control with full-speed range
If the engine is restarted automatically by the Stop & Start system during a
controlled stop by the dynamic radar cruise control with full-speed range, the
controlled stop will continue. (Resuming follow-up cruising after a controlled
stop: P. 335)

Press the Stop & Start cancel switch to
disable the Stop & Start system.
The Stop & Start cancel indicator will
come on. Pressing the switch again will enable theStop & Start system and the Stop & Start
cancel indicator will turn off.
■Automatic reactivation of the Stop & Start system
Even if the Stop & Start system is disabled by the Stop & Start cancel switch, it
will be automatically enabled when the engine switch is turned off, and then to
the engine started.
■If the Stop & Start cancel switch is pressed
●When the engine is stopped by the St op & Start system, pressing the Stop
& Start cancel switch will restart the engine.
●With the Stop & Start system disabl ed, pressing the Stop & Start cancel
switch will enable the system but no t stop the engine. From the next time
the vehicle is stopped (after the Stop & Start system has been enabled), the
engine will be stopped.
If the engine is stopped by the Stop & Start system when the vehicle is on an
incline, brake force is temporarily maintained to prevent rolling backwards until
the engine is restarted and drive force is generated. When drive force is gener-
ated, the maintained brake force is automatically canceled.
●This function operates on flat surfaces as well as steep inclines.
●Sound may be generated from the brak es, but this is not a malfunction.
●Brake pedal response may change and vibration may occur, but these are not
malfunctions.

• The battery is not sufficiently charged.
■Hood
●If the hood is opened while the engine is stopped by the Stop & Start system, the engine
will stall and will not be able to be restarte d by the automatic engine start function. In
this case, restart the engine using the normal engine starting procedure. (P. 246)
●If the hood is closed after the engine is st arted with the hood open, the Stop & Start sys-
tem will not operate. Close the hood, turn the engine switch off, wait 30 seconds or

the engine will stall and will not be able to be restarted by the automatic engine start
function. In this case, restart the engine using the normal engine starting procedure.
(  P. 246)
●When the engine is restarted by the Stop & Start system, the power outlets may be
temporarily unusable, but this is not a malfunction.

tem in order to reduce changes in the cabin temperature.
●To ensure air conditioning system performanc e when the vehicle is stopped, disable the Stop & Start system by pressing the Stop & Start cancel switch.
■Changing the idling stop time with the air conditioning system on
The length of time the Stop & Start system will operate when the air conditioning system
is on can be changed on the ( P. 109) or (P. 110). (The length of time the Stop
& Start system will operate when the air condit ioning system is off cannot be changed.)
■The Stop & Start system protection function
