Before driving
devices
• Another vehicle’s electronic key, another electronic key of your vehicle, or a wire-
less key that em its radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or
metallic objects are attached to the rear
window
●When the electronic key is placed near a
battery charger or electronic devices
●When the vehicle is parked in a pay park-
ing spot where radi o waves are emitted
■Note for the entry function
●Even when the electronic key is within the
effective range (detection areas), the sys-
tem may not operate properly in the fol-
lowing cases:
• The electronic key is too close to the win-
dow or outside door handle, near the
ground, or in a high place when the doors
are locked or unlocked.
• The electronic key is near the ground or in a high place, or too close to the rear
bumper center when the back door is
opened.
• The electronic key is on the instrument panel, luggage compar tment, floor, or in
the door pockets or glove box when the
hybrid system is star ted or power switch
modes are changed.
●Do not leave the electronic key on top of
the instrument panel or near the door
pockets when exiting the vehicle.
Depending on the ra dio wave reception
conditions, it may be detected by the
antenna outside the cabin and the door
will become lockable from the outside,
possibly trapping the electronic key
inside the vehicle.
●As long as the electronic key is within the
effective range, the doors may be locked
or unlocked by anyone.
●Even if the electronic key is not inside the
vehicle, it may be possible to start the
hybrid system if the el ectronic key is near
the window.
●The doors may unlock if a large amount of water splashes on the door handle,
such as in the rain or in a car wash when
the electronic key is
within the effective
range. (The door will automatically be
locked after approximately 60 seconds if
the doors are not opened and closed.)
●If the wireless remote control is used to
lock the doors when the electronic key is
near the vehicle, there is a possibility that
the door may not be unlocked by the
entry function. (Use the wireless remote
control to unlock the doors.)
●Touching the door lock sensor while
wearing gloves may delay or prevent lock
operation. Remove the gloves and touch
the lock sensor again.
●When the lock operation is performed
using the lock sensor, recognition signals
will be shown up to two consecutive
times. After this, no recognition signals
will be given.
●If the door handle becomes wet while the
electronic key is within the effective
range, the door may lock and unlock
repeatedly. In that case, follow the follow-
ing correction procedures to wash the
vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more away from the vehicle.
(Take care to ensure that the key is not
stolen.)
• Set the electronic key to battery-saving
mode to disable the smart access system
with push-button start. ( P.126)
●If the electronic key is inside the vehicle
and a door handle becomes wet during a
car wash, a message may be shown on
the multi-information display and a
buzzer will sound outside the vehicle. To
turn off the alarm, lock all the doors.
●The lock sensor may not work properly if
it comes into contact with ice, snow, mud,
etc. Clean the lock sensor and attempt to
operate it again.
●A sudden approach to the effective
range or door handle may prevent the
doors from being unlocked. In this case,
return the door handle to the original
position and check that the doors unlock
before pulling the door handle again.

the parking brake is released automatically
when shifting the shift lever to any position
other than P. ( P.194)
3Gradually release the brake pedal
and gently depress the accelerator
pedal to accelerate the vehicle.
■Stopping
1 With the shift lever in D, depress the
brake pedal.
2 If necessary, set the parking brake.
( P.193)
If the vehicle is to be stopped for an
extended period of time, shift the shift lever
to P or N. ( P.189)
■Parking the vehicle
1 With the shift lever in D, depress the
brake pedal.
2 Set the parking brake ( P.193),
and shift the shift lever to P
(  P.189).

Lock the door, making sure that you
have the electronic key on your
person.
If parking on a hill, block the wheels as
needed.
■Starting off on a steep uphill
1 With the brake pedal depressed,
shift the shift lever to D. ( P.189)
2 Pull the parking brake switch and
parking brake is set manually.
( P.193)
3 Release the brake pedal and gently

■When starting off on a uphill
The hill-start assist control will activate.
( P.279)
■For fuel-efficient driving
Keep in mind that hybr id vehicles are similar
to conventional vehicles, and it is necessary
to refrain from activities such as sudden
acceleration. ( P.284)
■Driving in the rain
●Drive carefully when it is raining, because
visibility will be re duced, the windows
may become fogged-u p, and the road
will be slippery.
●Drive carefully when it starts to rain,
because the road surface will be espe-
cially slippery.
●Refrain from high speeds when driving on
an expressway in the rain, because there
may be a layer of water between the tires
and the road surface, preventing the
steering and brakes from operating prop-
erly.
■Restraining the hybrid system output

The emergency flashers can be used.
2ACCESSORY mode
Some electrical components such as the
audio system can be used.
“ACCESSORY” will be displayed on the
meters.
3ON mode
All electrical components can be used.
“IGNITION ON” will be displayed on the
meters.
*: If the shift lever is in a position other than
P when turning off the hybrid system, the
power switch will be turned to ACCES-
SORY mode, not to off.
■Auto power off function
If the vehicle is left in ACCESSORY mode
for more than 20 minutes or ON mode
(with the hybrid system is not operating) for
more than an hour with the shift lever in P,
the power switch will automatically turn off.
WARNING
■Stopping the hybrid system in an
emergency
If you want to stop the hybrid system in an
emergency while driving the vehicle,
press and hold the power switch for more
than 2 seconds, or press it briefly 3 times
or more in succession. ( P.402)
However, do not touch the power switch
while driving except in an emergency.
Turning the hybrid system off while driv-
ing will not cause loss of steering or brak-
ing control, however, power assist to the
steering will be lost. This will make it
more difficult to st eer smoothly, so you
should pull over and stop the vehicle as
soon as it is safe to do so.
■When parking
Exhaust gases include harmful carbon
monoxide (CO), which is colorless and
odorless. Observe the following precau-
tions.
Failure to do so may cause exhaust gases
to enter the vehicle and may lead to an
accident caused by light-headedness, or
may lead to death or a serious health
hazard.
●If the vehicle is in a poorly ventilated
area or a closed area, such as a
garage, stop the hybrid system.
●Do not leave the vehicle with the
hybrid system operating for a long
time. If such a situation cannot be
avoided, park the vehicle in an open
space and ensure that exhaust fumes
do not enter the vehicle interior.
●Do not leave the hybrid system operat-
ing in an area with snow build-up, or
where it is snowing. If snowbanks build
up around the vehicle while the hybrid
system is operating, exhaust gases
may collect and enter the vehicle.

• When vehicle lanes are narrow, or when driving on the edge of a lane, and a vehi-
cle traveling in a lane other than the adja-
cent lanes enters the detection area
• When driving on roads with sharp bends,
consecutive curves, or uneven surfaces
• When the tires are slipping or spinning
• When the distance between your vehicle and a following vehicle is short

equipped)
Ultrasonic sensors are used to detect
static objects in the detection area
when driving at a low speed or backing
up. ( P.252)

function (if equipped)
Rear side radar sensors are used to
detect approaching vehicles in the
detection areas behind the vehicle

The Parking Support Alert system
consists of the following functions
that operate when driving at a low
speed or backing up, such as when
parking. When the system deter-
mines that the possibility of a colli-
sion with a detected object or such
as a wall is high, a warning operates
to urge the driver to take evasive
action.
