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 the warning area, the LKAS alerts you with slight steering
wheel vibration as well as a warning display.

Vehicle Stability Assist (VSA®), aka Electronic Stability Control (ESC), System

Continued

Driving

Vehicle Stability Assist (VSA®), aka Electronic
Stability Control (ESC), System

VSA® helps to stabilize the vehicle during cornering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine and motor output and selectively applying the
brakes.

When VSA® activates, you may notice that the
engine and motor do not respond to the
accelerator. You may also notice some noise
from the hydraulic system. You will also see
the indicator blink.

■

VSA® Operation

1

Vehicle Stability Assist (VSA®), aka Electronic Stability Control
(ESC), System

The VSA® may not function properly if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the air pressures as specified.

When the VSA® system indicator comes on and stays
on while driving, there may be a problem with the
system. While this may not interfere with normal
driving, have your vehicle checked by a dealer
immediately.

VSA® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and always leave a sufficient
margin of safety.

The main function of the VSA® system is generally
known as Electronic Stability Control (ESC). The
system also includes a traction control function.

This button is on the driver side control panel.
To partially disable VSA® functionality/
features, press and hold it until you hear a
beep.

The traction control stops fully functioning,
allowing the wheels to spin more freely at low
speed. The VSA® OFF indicator will also come
on.

To restore VSA® functionality/features, press
the

(VSA® OFF) button until you hear a

beep.

VSA® is turned on every time you turn the
power system on, even if you turned it off the
last time you drove the vehicle.

■

VSA® On and Off

1

Vehicle Stability Assist (VSA®), aka Electronic Stability Control
(ESC), System

With the

button pressed, your vehicle will have

normal braking and cornering ability, but VSA®
traction and stability enhancement becomes less
effective.

In certain unusual conditions when your vehicle gets
stuck in shallow mud or fresh snow, it may be easier
to free it with the VSA® temporarily switched off.

When the

button is pressed, the traction control

function becomes less effective. This allows for the
wheels to spin more freely at low speed. You should
only attempt to free your vehicle with the VSA® off if
you are not able to free it when the VSA® is on.

Immediately after freeing your vehicle, be sure to
switch VSA® on again. We do not recommend driving
your vehicle with the VSA® system switched off.

You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after turning the power
system on or while driving. This is normal.

Agile Handling Assist

Lightly brakes each of the front and rear wheels, as needed, when you turn the
steering wheel, and helps support the vehicle’s stability and performance during
cornering.

Agile Handling Assist

The agile handling assist cannot enhance stability in
all driving situations. You still need to drive and
corner at speeds appropriate for the conditions and
always leave a sufficient margin of safety.

When the VSA® system indicator comes on and stays
on while driving, the agile handling assist does not
activate.

You may hear a sound coming from the engine
compartment while the agile handling assist is
activated. This is normal.

SPORT HYBRID Super Handling-All Wheel Drive

TM

(SPORT HYBRID SH-AWD®)

The system controls and transfers varying amounts of motor and/or engine torque
to each wheel in accordance with the driving conditions.

SPORT HYBRID SH-AWD® helps to enhance driving stability, and lets you handle
situations like slippery surfaces, such as snow, sand, mud, and steep hills, better
than when driving with standard two wheel drive. However, the system does not
help to enhance braking. Be cautious about the following:
• It is still your responsibility to drive safely when you steer, accelerate, and apply

brakes.

• Leave a sufficient margin when braking on slippery surfaces.

Blind spot information (BSI) System

Continued

Driving

Blind spot information (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 approaching from behind in adjacent lanes, the
appropriate indicator comes on for a few seconds, providing assistance when you
change lanes.

■

How the system works

1

Blind spot information (BSI) System

Important Safety Reminder
Like all assistance systems, BSI has limitations. Over
reliance on BSI may result 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, etc.) even without the Blind
Spot Info Not Available MID appearing.

•

The BSI alert indicator may come on even with the
message appearing.

3

WARNING

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 when changing lanes.

Always look in your mirrors, to either side
of your vehicle, and behind you for other
vehicles before changing lanes.

Alert zone range
A: Approx. 1.6 ft. (0.5 m)
B: Approx. 10 ft. (3 m)
C: Approx. 10 ft. (3 m)

no more than 31 mph (50 km/h) from your
vehicle.

• You pass a vehicle with a speed difference

The BSI alert indicator may not come on under the
following conditions:

•

A vehicle does not stay in the alert zone for more
than two seconds.

•

A vehicle is parked in a side lane.

•

The speed difference between your vehicle and the
vehicle you are passing is greater than 6 mph (10
km/h).

•

An object not detected by the radar sensors
approaches or passes your vehicle.

•

A vehicle running in the adjacent lane is a
motorcycle or other small vehicle.

You can turn off the audible alert, or all the BSI alert
using the audio/information screen or MID.

2 Customizable Features P. 128

BSI may be adversely affected when:

•

Objects (guard rails, poles, trees, etc,.) are
detected.

•

An object that does not reflect radio waves well,
such as a motorcycle, is in the alert zone.

•

Driving on a curved road.

•

A vehicle is moving from a far lane to the adjacent
lane.

•

The system picks up external electrical interference.

•

The rear bumper or the sensors have been
improperly repaired or the rear bumper has been
deformed.

•

The orientation of the sensors has been changed.

•

In bad weather (Heavy rain, snow, and fog).

Tire Pressure Monitoring System (TPMS) with Tire Fill Assist

Driving

Tire Pressure Monitoring System (TPMS) with Tire
Fill Assist

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 MID.

1

Tire Pressure Monitoring System (TPMS) with Tire Fill Assist

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. 416

Tire pressure checked and inflated in:

•

Warm weather can become 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 tire that you
are adjusting using audible and visual indications.

If a change in tire pressure has been significant, the
system beeps and the hazard lights flash continuously
for five seconds when the specified tire pressure is
reached. Stop filling the tire.
