Resuming the prior set speed:
After cruise control has be en canceled, you can still
resume the prior set speed by pressing the RES/
ACCEL button while driving at a speed of at least 25
mph (40 km/h) or more.
You cannot set or resume in the following situations:

•When the MAIN button is turned off.
At vehicle speeds of 22 m ph (35 km/h) or less, cruise
control canceled automatically.

uuWhen Driving uLane Departure Warning (LDW)*
Continued
Driving
Lane Departure Warning (LDW)*
Alerts you when the system determines a possibility of your vehicle unintentionally
crossing over detected lane markings.
If your vehicle is getting too close to detected
left or right side lane markings without a turn
signal activated, LDW will give audible and
visual alerts.
The beeper sounds and the Lane Departure
message appears on the multi-information
display, letting you know that you need to
take appropriate action.
The system begins to search for lane mark ings when all the following conditions are
met:
• The vehicle is traveling between about 45 and 90 mph (72 and 145 km/h).
• The vehicle is on a straight or slightly curved road.
• The turn signals are off.
• The brake pedal is not depressed.
• The wipers are not in continuous operation.
■How the System Works
1Lane Departure Warning (LDW)*
Important Safety Reminder
Like all assistance systems, LDW has limitations.
Over-reliance on LDW may result in a collision. It is
always your respons ibility to keep the vehicle within
your driving lane.
LDW only alerts you when lane drift is detected
without a turn signal in us e. LDW may not detect all
lane markings or lane departures; a ccuracy will vary
based on weather, speed and lane marker condition.
It is always your responsibility to safely operate the
vehicle and avoid collisions.

camera equipped with this system. 2 Front Sensor Camera

uuWhen Driving uLane Keeping Assist System (LKAS)*
304
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
* P. 284
If the vehicle drifts toward ei ther left or right lane line
due to the system applying torque, turn off the LKAS
and have your vehicle checked by a dealer.

3. Keep your vehicle near the center of the
lane while driving.
u The dotted outer lines change to solid
ones once the system starts operating
after detecting the left and right lane
markings.
To cancel the LKAS:
Press the MAIN or LKAS button.
The LKAS is turned off every time you stop the
engine, even if you turned it on the last time
you drove the vehicle.

■The system operation is suspended if
you:
• Set the wipers to continuous operation.
u Turning the wipers off resumes the
LKAS.
• Decrease the vehicle speed to about 40
mph (64 km/h) or less.
u Increasing the vehicle speed to about 45
mph (72 km/h) or more resumes the
LKAS.
• Depress the brake pedal.
u The LKAS resumes and starts detecting
the lane lines again once you release the
brake pedal.
• Set the wiper switch to AUTO and the
wipers operate continuously.
u The LKAS resumes when the wipers stop
or operate intermittently.
■The LKAS may automatically be suspended when:
• The system fails to detect lane lines.
• The steering wheel is quickly turned.
• You fail to steer the vehicle.
• The vehicle runs on a curved road over the speed limit.
Once these conditions no longer exist, the LKAS automatically resumes.
When the LKAS is suspended,
the lane lines on the multi-
information disp lay change to
contour lines, and the beeper
sounds.

• The camera temperature gets too high.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
• When driving through a sharp curve.
• When driving at a speed in excess of approximately 90 mph (145 km/h).
• When the ABS or VSA ® systems engage.
A beeper will sound if the LKAS is automatically canceled.

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.

uuBraking uCollision Mitigation Braking SystemTM (CMBSTM)*
Driving
Collision Mitigati on Braking SystemTM (CMBSTM)*
Can assist you when there is a possibility of your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The CMBSTM is designed to alert you when a
potential collision is determined, as well as to reduce your vehicle speed to help
minimize collision severity when a collision is deemed unavoidable.
■How the system works
1 Collision Mitigation Braking SystemTM (CMBSTM)*
Important Safety Reminder
The CMBSTM is designed to reduce the severity of an
unavoidable collision. It does not prevent collision nor
stop the vehicle automatically. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately acco rding to the driving
conditions.
The CMBS
TM may not activate or may not detect a
vehicle in front of y our vehicle under certain
conditions:
2 CMBS
TM Conditions and Limitations P. 328
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera
* P. 284
The system starts monitoring the roadway ah ead when your vehicle speed is about
3 mph (5 km/h) and there is a vehicle in front of you. The radar sensor is
in the front grille.
The CMBS
TM activates when:●The speed difference between your vehicle and a vehicle or pedestrian
detected in front of you becomes about 3 mph (5 km/h) and over with a chance
of a collision.
●Your vehicle speed is about 62 mph (100 km/h) or less and there is a chance of a
collision with an oncoming detected vehicle or a pedestrian in front of you. The camera is
located behind the
rearview mirror.
