functions of the multi-information
display.
The radar sensor for ACC is shared
with the collision mitigation braking
system™(CMBS™). For more

Overview
Adaptive cruise control (ACC) allows
you to maintain a set speed and keep
the vehicle ahead of you and your
vehicle at a safe distance without
having to use the accelerator pedal or
the brake pedal.
When the vehicle ahead of you slows
down or speeds up, ACC senses the
change in distance and compensates
by adjusting your vehicle speed
accordingly. The distance between
vehicles is based on your speed: the
faster you go, the longer the distance
will be; the slower you go, the
shorter it will be.If the vehicle ahead of you slows
down suddenly or another vehicle
cuts in front of your vehicle, ACC
alerts you by sounding a beeper and
displaying a message on the multi-
information display.
The ACC radar sensor in the front
grille can detect and monitor the
distance of a vehicle up to 328 feet
(100 meters) ahead of your vehicle.
For more information on the radar
sensor, see page 464.
Important Safety Precautions
As with any system, there are limits
to ACC. Inappropriate use of ACC
can result in a serious accident. Use
the brake pedal whenever necessary,
and always keep a safe distance
between your vehicle and other
vehicles.Do not use ACC under these
conditions:
●
In poor visibility.
●
In heavy traffic.
●
When you must slow down and
speed up repeatedly.
●
On winding roads.
●
When you enter a toll gate,
interchange, service area, parking
area, etc. In these areas, there is
no vehicle ahead of you, but ACC
would still try to accelerate to your
set speed.
●
In bad weather (rain, fog, snow,
etc.)
●
On a slippery road (for example a
road covered with ice or snow).

Features

On models without navigation systemYou can turn the camera display on
and off by pressing the power button
when the shift lever is in reverse.
The camera display turns on
everytime you shift to reverse, even if
you turned it off the last time.
Whenever you shift to reverse (R)
with the ignition switch in the ON
(II) position, the rearview appears on
a display in the rearview mirror.
For the best picture, always keep the
rearview camera clean, and do not
cover the camera lens. To avoid
scratching the lens when you clean
it, use a moist, soft cloth.
Since the rearview camera display
area is limited, you should always
back up slowly and carefully, and
look behind you for obstacles.If the engine has just been started, it
may take a short time for the system
to display the rearview.
The camera display brightness is
adjusted automatically by sensors. If
you use the camera display
continuously at high temperatures,
the image will gradually dim.
The rearview mirror will be hot when
you use the camera display for an
extended period of time.
If a bright light (such as sunlight) is
reflected on the mirror, the image
may be difficult to see.

Carrying Cargo in the Passenger
Compartment●
Store or secure all items that could
be thrown around and hurt
someone during a crash.
●
Be sure items placed on the floor
behind the front seats cannot roll
underneath and interfere with the
proper operation of the seats, the
sensors under the seats, or the
driver's ability to operate the
pedals.
Also, keep all cargo below the
bottom of the windows. If it is
higher, it could interfere with the
proper operation of the side
curtain airbags.
●
Keep the glove box closed while
driving. If it is open, a passenger
could injure their knees during a
crash or sudden stop.Carrying Cargo in the Cargo Area
or on a Roof Rack
●
Distribute cargo evenly on the
floor of the cargo area, placing the
heaviest items on the bottom and
as far forward as possible. Tie
down items that could be thrown
about the vehicle during a crash or
sudden stop.
●
If you fold down the second or
third row seats, tie down items that
could be thrown about the vehicle
during a crash or sudden stop.
●
If you carry large items that
prevent you from closing the
tailgate, exhaust gas can enter the
passenger area. To avoid the
possibility ofcarbon monoxide
poisoning,follow the instructions
on page 61.
●
If you carry any items on a roof
rack, be sure the total weight of
the rack and the items does not
exceed 165 lbs (75 kg).
