QAUTO mode can be used when
The power switch is in ON mode.
QDaytime running light system
OThe daytime running lights illuminate
using the same lights as the parking lights
and illuminate brighter than the parking
lights.
OTo make your vehicle more visible to
other drivers during daytime driving, the
daytime running lights turn on automati-
cally when all of the following conditions
are met. (The daytime running lights are
not designed for use at night.)
• The hybrid system is operating
• The parking brake is released
• The headlight switch is in the or
* position
*: When the surroundings are bright
The daytime running lights remain on after
they illuminate, even if the parking brake is
set again.
OFor the U.S.A.: Daytime running lights
can be turned off by operating the head-
light switch to position.
OCompared to turning on the headlights,
the daytime running light system offers
greater durability and consumes less
electricity, so it can help improve fuel
economy.
QHeadlight 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 wind-
shield.
Doing so interferes with the sensor detect-
ing the level of ambient light and may cause
the automatic headlight system to malfunc-
tion.
Headlight switch
The headlights can be operated
manually or automatically.

Driving
OHouse lights, street lights, traffic signals,
and illuminated billboards or signs may
cause the high beam to switch to the low
beams, or the low beams to remain on.
OThe following factors may affect the
amount of time taken to turn the high
beam on or off:
• The brightness of headlights, fog lights,
and tail lights of vehicles ahead
• The movement and direction of vehicles ahead
• When a vehicle ahead only has opera- tional lights on one side
• When a vehicle ahead is a two-wheeled
vehicle
• The condition of the road (gradient, curve, condition of the road surface etc.)
• The number of passengers and amount of luggage
OThe high beam may be turned on or off
when the driver does not expect it.
OBicycles or similar objects may not be
detected.
OIn the situations shown below, the system
may not be able to accurately detect sur-
rounding brightness levels. This may
cause the low beams to remain on or the
high beams to cause problems for pedes-
trians, vehicles ahead or other parties. In
these cases, manually switch between the
high and low beams.
• In bad weather (rain, snow, fog, sand-
storms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged
• The front camera is deformed or dirty
• When the temperature of the front cam- era is extremely high
• Surrounding brightness levels are equal to those of headlights, tail lights or fog
lights
• When headlights or tail lights of vehicles ahead are turned off, dirty, changing
color, or not aimed properly
• When the vehicle is hit by water, snow,
dust, etc. from a preceding vehicle
• When driving through an area of inter- mittently changing brightness and dark-
ness
• When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces
(such as stone-paved roads, gravel roads
etc.)
• When frequently and repeatedly taking curves or driving on a winding road
• There is a highly reflective object ahead
of the vehicle, such as a sign or a mirror
• The back of a vehicle ahead is highly reflective, such as a container on a truck.
• The vehicle’s headlights are damaged or dirty
• The vehicle is listing or tilting, due to a flat
tire, a trailer being towed etc.
• The high beam and low beam are repeat- edly being switched between in an
abnormal manner
• The driver believes that the high beam may be causing problems or distress to
other drivers or pedestrians nearby
QTemporarily lowering sensor sensitivity
The sensitivity of the sensor can be tempo-
rarily lowered.

2064-5. Using the driving support systems
This mode employs a radar to detect the presence of vehicles up to approximately
328 ft. (100 m) ahead, determines the current vehicle-to-vehicle following dis-
tance, 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 down hill slopes, the vehicle-to-vehicle distance may become shorter.
Example of constant speed cruising
When there are no vehicles ahead
WARNING

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

Driving
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 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 th is 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 sufficiently to
prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicl e will also stop (vehicle is stopped by sys-
tem control). After the vehicle ahead starts off, pressing the “+RES” switch or depressing
the accelerator pedal (start-off operation) will resume follow-up cruising. If the start-off
operation is not performed, system contro l continues to keep your vehicle stopped.
When the turn signal lever is operated and your vehicle moves to an overtaking lane while
driving at 50 mph (80 km/h) or more, the vehicle will accelerate to help to overtake a
passing vehicle.
The system’s identification of what is an overtaking lane may be determined solely based on
the location of the steering wheel in the vehicl e (left side driver position versus right side
driver position.) If the vehicle is driven to a region where the overtaking lane is on a differ-
ent side from where the vehicle is normally driven, the vehicle may accelerate when the
turn signal lever is operated in the opposite direction to the overtaking lane (e.g., if the
driver normally operates the vehicle in a region where the overtaking lane is to the right but
then drives to a region where the overtaking lane is to the left, the vehicle may accelerate
when the right turn signal is activated).
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.
1 Press the cruise control main
switch to activate the cruise con-
trol.
Dynamic radar cruise control indicator will
come on and a message will be displayed
on the multi-information display. Press the
switch again to deactivate the cruise con-
trol. If the cruise control main switch is pressed
and held for 1.5 seconds or more, the sys-
tem turns on in constant speed control
mode. (
