CAUTION
■When using the rear view monitor system
When backing up, be sure to check visually behind and all around the vehicle
before proceeding.
Observe the following precautions to avoid an accident that could result in death
or serious injuries.
●The rear view monitor system is a supplemental device intended to assist the
driver when backing up. Never depend on the rear view monitor system entirely
when backing up. Always make sure your intended path is clear.
Use caution, just as you would when backing up any vehicle.
●Never back up while looking only at the screen.
The image shown on the screen may differ from the actual state, and you could
collide with another vehicle or obstacles if backing up looking only at the screen,
possibly causing an accident. When backing up, be sure to check in front of and
behind the vehicle, both directly and with mirrors.
●Be sure to back up slowly, depressing the brake pedal to control vehicle speed.
●The instructions given are only guidelines.
When and how much to turn the steering wheel will vary according to traffic con-
ditions, road surface conditions, vehicle condition, etc. when parking. It is neces-
sary to be fully aware of this before using the rear view monitor system.
●When parking, be sure to check that the parking space will accommodate your
vehicle before maneuvering into it.
●Do not use system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or the compact spare tire
• When the trunk lid is not closed completely
• On roads that are not flat or straight, such as curves or slopes.
●In low temperatures, the screen may darken or the image may become faint. The
image could distort when the vehicle is moving, or you may become unable to
see the image on the screen. Be sure to check direct visually and with mirror all
around the vehicle before proceeding.
●If the tire sizes are changed, the position of the fixation guide lines displayed on
the screen may change.
●The camera uses a special lens. The distances between objects and pedestrians
that appear in the image displayed on the screen will differ from the actual dis-
tances. (→P. 2 8 7 )

Hill-start assist control (hybrid vehicles)
To engage hill-start assist control,
further depress the brake pedal
when the vehicle is stopped com-
pletely.
A buzzer will sound once to indicate
the system is activated. The slip indica-
tor will also start flashing.
■Hill-start assist control operating conditions
●The system operates in the following situations:
• The shift lever is in a position other than P.
• The parking brake is not applied.
• The accelerator pedal is not depressed.
●Hill-start assist control cannot be operated while the slip indicator light is illumi-
nated.
■Hill-start assist control
●While hill-start assist control is operating, the brakes remain automatically applied
after the driver releases the brake pedal. The stop lights and the high mounted
stoplight turn on.
●Hill-start assist control operates for about 2 seconds after the brake pedal is
released.
●If the slip indicator does not flash and the buzzer does not sound when the brake
pedal is further depressed, slightly reduce the pressure on the brake pedal (do not
allow the vehicle to roll backward) and then firmly depress it again. If the system still
does not operate, check that the operating conditions explained above have been
met.
Assists with starting off and temporarily maintains braking power even
if the foot is removed from the brake pedal when starting off on an
incline or a slippery slope.

■Hill-start assist control buzzer
●When hill-start assist control is activated, the buzzer will sound once.
●In the following situations, hill-start assist control will be canceled and the buzzer
will sound twice.
• No attempt is made to drive the vehicle within approximately 2 seconds ofreleasing the brake pedal.
• The shift lever is moved to P.
• The parking brake is applied.
• The brake pedal is depressed again.
• The brake pedal has been depressed for more than approximately 3 minutes.

CAUTION
■Hill-start assist control
●Do not overly rely on hill-start assist control. Hill-start assist control may not oper-
ate effectively on steep inclines and roads covered with ice.
●Unlike the parking brake, hill-start assist control is not intended to hold the vehi-
cle stationary for an extended period of time. Do not attempt to use hill-start
assist control to hold the vehicle on an incline, as doing so may lead to an acci-
dent.
