uuWhen Driving uAdaptive Cruise Control (ACC)*
Driving
■There is a vehicle ahead
ACC monitors if a vehicle ahead of you enters the ACC range. If a vehicle is detected
doing so, the ACC system maintains or decele rates your vehicle’s set speed in order
to keep the vehicle’s set followi ng-distance from the vehicle ahead.
2To Change Vehicle Distance P. 292
■When in Operation1When in Operation
If the vehicle detected ahead of you slows down
abruptly, or if a nother vehicle is de tected cutting in
front of you, the beep er sounds and a message
appears on the multi-informat ion display to alert you
to brake.
Depress the brake pedal, and keep an appropriate
distance from the vehicle ahead.
Even if the distance betw een your vehicle and the
vehicle detected ahead is short, ACC may start
accelerating your vehi cle under the following
circumstances:
•The vehicle ahead of you is going at almost the
same speed as, or fast er than your vehicle.
•A vehicle that cuts in front of you is going faster
than your vehicle, gradua lly distancing itself from
you.

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.

uuWhen Driving uBlind spot information (BSI) System*
Continued
Driving
Blind spot informa tion (BSI) System*
Is designed to detect vehicles in specified alert zones adjacent to your vehicle,
particularly in harder to see areas commonly known as “blind spots.”
When the system detects vehicles approach ing from behind in adjacent lanes, the
appropriate indicator comes on for a few se conds, providing assistance when you
change lanes.
■How the system works
1 Blind spot inform ation (BSI) System*
Important Safety Reminder
Like all assistance systems, BSI has limitations. Over
reliance on BSI may re sult in a collision.
The system is for your convenience only. Even if an
object is within the alert zone, the following
situations may occur.
•The BSI alert indicator may not come on due to
obstruction (splashes, et c.) even without the BLIND
SPOT NOT AVAILABLE/Blind Spot Info Not
Available multi-information display appearing.
•The BSI alert indicator may come on even with the
message appearing.
3WARNING
Failure to visually confirm that it is safe to
change lanes before doing so may result in
a crash and serious injury or death.
Do not rely only on the blind spot
information system wh en changing lanes.
Always look in your mirrors, to either side
of your vehicle, and behind you for other
vehicles before changing lanes.
Radar sensors detect a
vehicle in the alert zone
when your vehicle is
moving forward at
between 20 mph (32 km/h)
and 100 mph (160 km/h). Alert zone range

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. 380
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.

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 uBrake System
Driving
Your vehicle is equipped with disc brakes at all four wheels. A vacuum power assist
helps reduce the effort needed on the brake pedal. The brake assist system increases
the stopping force when you depress the brake pedal hard in an emergency
situation. The anti-lock brake system (ABS) helps you retain steering control when
braking very hard.
2 Brake Assist System P. 321
2 Anti-lock Brake System (ABS) P. 320
■Foot Brake1Foot Brake
Check the brakes after driving through deep water,
or if there is a buildup of road surface water. If
necessary, dry the brakes by lightly depressing the
pedal several times.
If you hear a continuous me tallic friction sound when
applying the brakes, this is caused by the brake wear
indicator rubbing on the brake rotor and indicates
that the brake pads need to be replaced. Have the
vehicle checked by a deal er. If you hear only an
occasional squeak or squeal when you initially apply
the brake pedal, this may be normal and caused by
high frequency vibr ation of the brake pads against
the rotating brake disc.
Constantly using the brak e pedal while going down a
long hill builds up heat, which reduces the brake
effectiveness. Apply engine braking by taking your
foot off the accelerator pe dal and downshifting to a
lower gear.
Do not rest your foot on the brake pedal while
driving, as it will lightly apply the brakes and cause
them to lose effectiveness over time and reduce pad
life. It will also conf use drivers behind you.
Your vehicle is equipped with a hydraulic brake
booster that, under certain conditions, such as
braking at high altitudes, supplements the vacuum
power assist. When the hydraulic brake booster
activates, you may hear a motor sound and a slight
vibration in the pedal. This is normal.
