(LKAS).
Do not use the ACC under the following conditions.
•On roads with heavy traf fic or while driving in
continuous stop and go traffic.
•On roads with sharp turns.•On roads with steep downhill sections, as the set
vehicle speed can be exceeded by coasting. In such
cases, the ACC will not apply the brakes to
maintain the set speed.
•On roads with toll collection facilities or other
objects between lanes of traffic, or in parking
areas, or faci lities with driv e through access.

Driving
Lane Keeping Assist System (LKAS)*
Provides steering input to help keep the vehicle in the middle of a detected lane and
provides audible and visual alerts if the vehicle is detected drifting out of its lane.1Lane Keeping Assist System (LKAS)*
Important Safety Reminders
The LKAS is for your convenience only. It is not a
substitute for your vehicl e control. The system does
not work if you take y our hands off the steering
wheel or fail to steer the vehicle.
2 Multi-Information Display Warning and
Information Messages P. 93
Do not place objects on the instrument panel.
Objects may reflect on th e front windshield and
prevent correct detectio n of the traffic lanes.
LKAS only alerts you when lane drift is detected
without a turn signal in use. LKAS may not detect all
lane markings or lane departures; a ccuracy will vary
based on weather, speed, an d lane marker condition.
It is always your responsibility to safely operate the
vehicle and avoid collisions.
The LKAS is convenient when it is used on freeways.
The LKAS may not work properly or may work
improperly under the certain conditions: 2 LKAS Conditions and Limitations P. 309
Beeps and a warning display alert you
that the vehicle is drifting out of a
detected lane.
When you operate the turn signals to chan ge lanes, the system is suspended, and
resumes after the signals are off.
If you make a lane change without operat ing the turn signals, the LKAS alerts
activate, and torque is applied to the steering.

Driving
Provides assistance to keep the vehicle in the center of the lane. When the vehicle
nears a white or yellow line, steering force of the electric power steering will become
stronger.
When the vehicle enters th e warning area, LKAS alerts you with beeps as well a
warning display.
■Lane Keep Support Function1 Lane Keeping Assist System (LKAS)*
The LKAS may not functi on as designed on while
driving in frequent stop and go traffic, or on roads
with sharp curves.
When it fails to detect lanes, the system will
temporarily be cancelled. When lane is detected,
system will recover automatically.
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera

uuWhen Driving uAll-Wheel Drive (AWD) with Intelligent Control System*
Driving
All-Wheel Drive (AWD) with Intelligent Control System*
Your vehicle is equipped with the AWD wi th intelligent control system. When the
system senses a loss of front wheel tracti on, it automatically transfers some power
to the rear wheels. This allows you to ut ilize all available traction and may increase
mobility.
You still need to exercise the same care when accelerating, steering, and braking
that you would in a two wheel drive vehicle.
If you excessively spin all four wheels and overheat the AWD with intelligent control
system, only the front wheels receive power. Stop until the system cools down.
Tire Pressure Monitoring System (TPMS)
Monitors the tire pressure while you are
driving. If your vehicle’s tire pressure becomes
significantly low, the low tire pressure/TPMS
indicator comes on and a message appears on
the multi-information display.
1 All-Wheel Drive (AWD) with Intelligent Control System*
NOTICE
Do not continuously spin the front tires of your
vehicle. Continuously spinning the front tires can
cause transmission or re ar differential damage.
The AWD with intelligent control system may not
function properly if tire ty pe and size are mixed.
Make sure to use the same size and type of tire, and
the air pressures as specified.
2 Tire and Wheel Replacement P. 382
1Tire Pressure Monitoring System (TPMS)
Conditions such as low ambient temperature and
altitude change directly affect tire pressure and can
trigger the low tire pressure/TPMS indicator to come
on.
2 If the Low Tire Pressure/TPMS Indicator
Comes On or Blinks P. 425
Tire pressure checked and inflated in:
•Warm weather can beco me under-inflated in
colder weather.
•Cold weather can become over-inflated in warmer
weather.
The low tire pressure/TPMS indicator will not come
on as a result of over inflation.
The TPMS audibly and visually informs you of
changes in tire pressure of the individual ti re that you
are adjusting using audibl e and visual indications.
