Cruise control allows you to maintain
a set speed above 25 mph (40 km/h)
without keeping your foot on the
accelerator pedal. It should be used
for cruising on straight, open
highways. It is not recommended for
city driving, winding roads, slippery
roads, heavy rain, or bad weather.
Improper use of the cruise
control can lead to a crash.
Use the cruise control only
when traveling on open
highways in good weather.Using Cruise Control
1. Push in the CRUISE button or
MAIN button (models with
adaptive cruise control) on the
steering wheel. The CRUISE

controlTo switch from ACC to cruise
control, press the distance button
on the steering wheel, and hold it
for 1 second (see page 362).

Cruise control may not hold the set
speed when you are going up and
down hills. If your vehicle speed
increases going down a hill, use the
brakes to slow down. This will cancel
the cruise control. On models with
adaptive cruise control (ACC), this
also causes the cruise control
indicator on the instrument panel to
go off and the cruise mode indicator
to come on. To resume the set speed,
press the RES/ACCEL button. The
CRUISE CONTROL indicator on the
instrument panel will come back on.Changing the Set Speed
You can increase the set cruising
speed in any of these ways:
●
Press and hold the RES/ACCEL
button. When you reach the
desired cruising speed, release the
button.
●
Push on the accelerator pedal.
Accelerate to the desired cruising
speed, then press the SET/
DECEL button.
●
To increase the speed in very
small amounts, tap the RES/
ACCEL button. Each time you do
this, your vehicle will speed up
about 1 mph (1.6 km/h).You can decrease the set cruising
speed in any of these ways:
●
Press and hold the SET/DECEL
button. Release the button when
you reach the desired speed.
●
To slow down in very small
amounts, tap the SET/DECEL
button. Each time you do this,
your vehicle will slow down about
1 mph (1.6 km/h).
●
Tap the brake pedal lightly with
your foot. The CRUISE CONTROL
indicator on the instrument panel
will go out. When the vehicle

ACC ComponentsIf equippedAdaptive cruise control (ACC)
consists of a radar sensor in the front
grille, the MAIN buttons on the
steering wheel, and the ACC
functions of the multi-information
display.
The radar sensor for ACC is shared
with the collision mitigation braking
system™(CMBS™). For more
information on the radar sensor, see
page 464. For more information on
CMBS, see page 463.

Adaptive Cruise Control (ACC)348

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

Improper use of ACC can lead
to a crash.
Use ACC only when traveling
on open highways in good
weather.Operating Characteristics
When there is no vehicle ahead within
ACC rangeYour vehicle will maintain a set
cruising speed.
When a vehicle ahead is within ACC
range and going slower than your set
speedIf the vehicle ahead of you is going
slower than your set speed, your
vehicle will slow down to the speed
of that vehicle. Your vehicle will then
follow at a constant distance until the
vehicle ahead changes speed again.
Adaptive Cruise Control (ACC)350

If the vehicle ahead of you slows
down abruptly, or if another vehicle
cuts in front of you, a beeper sounds
and a message appears on the multi-
information display to warn you.
In this case, decelerate your vehicle
by pressing the brake pedal, and
keep an appropriate distance from
the vehicle ahead.
When a vehicle ahead is within ACC
range and going at a steady speedYour vehicle follows the vehicle
ahead of it, keeping a constant
distance. ACC will not keep your
vehicle at a constant distance if the
vehicle ahead of you goes out of
range of your set speed.
If the vehicle ahead of you slows
down and changes lanes, ACC no
longer tracks it. Your vehicle will
then return to your set speed.

Features

Limitations●
ACC does not work below 25 mph
(40 km/h). It cannot bring your
vehicle to a complete stop.
●
ACC will not sound a beeper or
display a message on the multi-
information display to warn you of
vehicles going slower than 13 mph
(20 km/h) or vehicles that are
parked. In these cases, it is up to
you to maintain a safe distance by
using the brake pedal.
●
ACC may not recognize
motorcycles or other small
vehicles ahead of your vehicle.
●
ACC may react to vehicles beside
you or even a building beside you
by momentarily applying the
brakes or sounding a beeper
under conditions such as a sudden
curve or narrowing of the road, an
abrupt movement of the steering
wheel, or if you are in an unusual
position within your lane.
Adaptive Cruise Control (ACC)352

Using the ACC1. Push the MAIN button on the
steering wheel. The ACC indicator
on the instrument panel comes on,
and‘‘ACC’’is shown on the multi-
information display.
2. Accelerate to the desired speed
above 25 mph (40 km/h).
3. Press and release the SET/
DECEL button on the steering
wheel, then release the accelerator
pedal.
If you press the SET/DECEL button
when the vehicle speed is below 25
mph (40 km/h), you will hear a beep
for about 1 second. This means ACC
is not activated, and you cannot set
your speed.
When your speed reaches 25 mph
(40 km/h), ACC goes into wait
mode, and‘‘ACC’’is shown on the
multi-information display.
