NOTICE
■Before driving
Fully release the parking brake.
Driving the vehicle with the parking brake set will lead to brake components
overheating, which may affect braking performance and increase brake
wear.
To set the parking brake, fully
depress the parking brake
pedal with your left foot while
depressing the brake pedal
with your right foot.
(Depressing the pedal again
releases the parking brake.)

Turning on the high beam headlights
With the headlights on, push
the lever away from you to
turn on the high beams.
Pull the lever toward you to the
center position to turn the high
beams off.
Pull the lever toward you and
release it to flash the high
beams once.
You can flash the high beams
with the headlights on or off.
■Daytime running light system
●For the U.S.A.: To make your vehicle more visible to other drivers, the
daytime running lights turn on automatically whenever the hybrid system
is started and the parking brake is released.
Daytime running lights can be turned off by operating the switch. (if
equipped)
For Canada: To make your vehicle more visible to other drivers, the day-
time running lights turn on automatically (at a reduced intensity) whenever
the hybrid system is started and the parking brake is released. Daytime
running lights are not designed for use at night.
● For Canada: 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.

■Adjusting the set speed
To change the set speed, operate the lever until the desired set
speed is obtained.
Increases the speed
Decreases the speed
Fine adjustment: Momentarily
move the lever in the desired
direction.
Large adjustment: Hold the
lever in the desired direction.
The set speed will be increased or decreased as follows:
Fine adjustment: By approximately 1 mph (1.6 km/h) each time
the lever is operated.
Large adjustment: The set speed can be increased or
decreased continually until the lever is released.
■ Canceling and resuming the constant speed control
Pulling the lever toward you
cancels the constant speed
control.
The speed setting is also can-
celed when the brakes are
applied.
Pushing the lever up
resumes the constant
speed control.
Resuming is available when
the vehicle speed is more
than approximately 25 mph
(40 km/h).

When driving
■Canceling and resuming the speed control
Pulling the lever toward you
cancels the cruise control.
The speed setting is also can-
celed when the brakes are
applied.
Pushing the lever up
resumes the cruise control
and returns vehicle speed
to the set speed.
Resuming is available when
the vehicle speed is more
than approximately 25 mph
(40 km/h).

When driving
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 control.
Example of deceleration cruising
When the vehicle ahead is driving slower than the set speed
When a vehicle is detected running ahead of you, the system automati-
cally decelerates your vehicle. When a greater reduction in vehicle speed
is necessary, the system applies the brakes. A warning tone warns you
when the system cannot decelerate sufficiently to prevent your vehicle
from closing in on the vehicle ahead.
Example of follow-up cruising
When following a vehicle driv ing slower than the set speed
The system continues follow-up cruising while adjusting for changes in the
speed of the vehicle ahead in order to maintain the vehicle-to-vehicle dis-
tance set by the driver.
Example of acceleration
When there are no longer any vehi cles ahead driving slower than
the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.

Approach warningWhen your vehicle is too close to a vehicle ahead, and sufficient
automatic deceleration via the cruise control is not possible, the dis-
play will flash and the bu zzer will sound to alert the driver. An exam-
ple of this would be if another driver cuts in front of you while you are
following a vehicle. Apply the brakes to ensure an appropriate vehi-
cle-to-vehicle distance.
■ Warnings may not occur when
In the following instan ces, there is a possibility that the warnings
will not occur:
● When the speed of the vehicl e ahead matches or exceeds your
vehicle speed
● When the vehicle ahead is traveling at an extremely slow speed
● Immediately after the cruise control speed was set
● At the instant the accelerator is applied

CAUTION
■Before using dynamic radar cruise control
Do not overly rely on vehicle-to-vehicle distance control.
Be aware of the set speed. If automatic deceleration/acceleration is not
appropriate, adjust the vehicle speed, as well as the distance between your
vehicle and vehicles ahead by applying the brakes etc.
■ Cautions regarding the driving assist systems
Observe the following precautions.
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 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 mechanism that allows care-
less 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 determines whether the following dis-
tance between the driver’s own vehicle and a designated vehicle traveling
ahead is appropriate or not. It is not capable of making any other type of
judgement. Therefore, it is absolutely necessary for the driver to remain
vigilant and to determine whether or not there is a possibility of danger in
any given situation.
● Assisting the driver to operate the vehicle
The dynamic radar cruise control has no capability to prevent or avoid a
collision with a vehicle traveling ahead. Therefore, if there is ever any dan-
ger, the driver must take immediate and direct control of the vehicle and
act appropriately in order to ensure the safety of all involved.

CAUTION
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes (or accelerator pedal) as necessary when any of the follow-
ing types of vehicles are in front of you.
As the sensor may not be able to correctly detect these types of vehicles,
the approach warning ( P. 280) will not be activated, and a fatal or serious
accident may result.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving
● Vehicles with small rear ends (trailers with no load on board etc.)
● Motorcycles traveling in the same lane
● Vehicles splashing up water or snow
■ Conditions under which the vehicle -to-vehicle distance control may
not function correctly
Apply the brakes (or accelerator pedal) as necessary in the following condi-
tions as the radar sensor may not be able to correctly detect vehicles a\
head,
and a fatal or serious accident may result:
● When water or snow thrown up by the surrounding vehicles hinders the
functioning of the sensor
● When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment etc.)
● When the road curves or when the lanes are narrow
● When steering wheel operation or your position in the lane is unstable
● When the vehicle ahead of you decelerates suddenly
