Quick Reference Guide
What to Do If
Why does the brake pedal
pulsate slightly when
applying the brakes?This can occur when the ABS activates and does not indicate a
problem. Apply firm, steady pressure on the brake pedal. Never
pump the brake pedal.
2Anti-lock Brake System (ABS) (P 456)
The rear door cannot be
opened from inside the
vehicle. Why?Check if the childproof lock is in
the LOCK position. If so, open the
rear door with the outside door
handle.
To cancel this function, slide the
lever to the UNLOCK position.
Why do the doors lock
after I unlocked the doors?If you do not open the doors within 30 seconds, the doors are
relocked automatically for security.
Why does the beeper
sound when I open the
driver’s door?The beeper sounds when:
●The power mode is in ACCESSORY.
●The exterior lights are left on.

uuWhen Driving uAdaptive Cruise Control (ACC) with Low Speed Follow
Driving
Adaptive Cruise Control (ACC) with Low Speed
Follow
Helps maintain a constant vehicle speed an d a set following-interval behind a vehicle
detected ahead of yours and, if the detected vehicle comes to a stop, decelerates
and stop your vehicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with Low Speed Follow slows y our vehicle by applying the brakes, your
vehicle's brake lights will illuminate.
1 Adaptive Cruise Control (ACC) with Low Speed Follow
Important Reminder
As with any system, there are limits to ACC with Low
Speed Follow. Use the brake pedal whenever
necessary, and always keep a safe interval between
your vehicle and other vehicles.
3WARNING
Improper use of ACC with Low Speed
Follow can lead to a crash.
Use ACC with Low Speed Follow only when
driving on expressways or freeways and in
good weather conditions.
3WARNING
ACC with Low Speed Follow has limited
braking capability and may not stop your
vehicle in time to avoid a collision with a
vehicle that quickly stops in front of you.
Always be prepared to apply the brake
pedal if the conditions require.
When to use
■Vehicle speed for ACC wi th Low Speed Follow: A vehicle is detected ahead within
ACC with Low Speed Follow range – ACC with Low Speed Follow operates at
speeds up to 90 mph (145 km/h).
No vehicle is detected within ACC with Low Speed Follow range – ACC with Low
Speed Follow operates at the speed of 25 mph (40 km/h) or above.
■Gear position for ACC with Low Speed Follow: In ( D.
The radar sensor is
in the front grille.
The camera is
located behind
the rearview
mirror.

Driving
■Detection limitations
• A vehicle suddenly crosses in front of you.
• The interval between your vehicle and the vehicle ahead of you is too short.
• A vehicle cuts in front of you at a slow speed, and it brakes suddenly.
• When you accelerate rapidly and approach the vehicle ahead of you at high
speed.
• The vehicle ahead of you is a motorcycle, bicycle, mobility scooter, or other small
vehicle.
• When there are animals in front of your vehicle.
• When you drive on a curved or winding or undulating road that makes it difficult
for the sensor to properly detect a vehicle in front of you.
• The speed difference between your vehicl e and a vehicle in front of you is
significantly large.
• An oncoming vehicle suddenly comes in front of you.
• Your vehicle abruptly crosses over in front of an oncoming vehicle.
• When driving through a narrow iron bridge.
• When the vehicle ahead of you brakes suddenly.
• When the vehicle ahead of you has a unique shape.
• When your vehicle or the vehicle ahead of you is driving on one edge of the lane.1ACC with Low Speed Follow Conditions and Limitations
If the front of the vehicle is impacted in any of the
following situations, the ra dar sensor may not work
properly. Have your vehi cle checked by a dealer:
•The vehicle mounted onto a bump, curb, chock,
embankment, etc.
•You drive the vehicle where the water is deep.
•Your vehicle has a frontal collision.

Driving
Vehicle Stability AssistTM (VSA ®), aka Electronic
Stability Control (ESC), System
VSA ® helps to stabilize the vehicle during corn ering 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 AssistTM (VSA® ), aka Electronic Stability Control
(ESC), System
The VSA ® may not function properl y 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 ma y be a problem with the
system. While this may not interfere with normal
driving, have your vehi cle checked by a dealer
immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the en tire 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 Stab ility Control (ESC). The
system also includes a traction control function.

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.1 Agile Handling Assist
The agile handling assist ca nnot 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 agil e 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.

uuWhen Driving uSPORT HYBRID Super Handling-All Wheel DriveTM (SPORT HYBRID SH-AWD® )
Driving
SPORT HYBRID Super Handling-All Wheel DriveTM
(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.
1SPORT HYBRID Super Handling-All Wheel DriveTM (SPORT
HYBRID SH-AWD ®)
Do not drive through deep water.
The SPORT HYBRID SH-AWD ® system 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. 2 Tire and Wheel Replacement P. 526

Braking
Brake System
Use the parking brake to keep the vehicle stationary when parked. When the
parking brake is applied, you can ma nually or automatically release it.
■To apply
The electric parking brake can be applied any
time the vehicle has battery, no matter which
power mode the vehicle is in.
Pull the electric parkin g brake switch up gently
and securely. u The electric parking brake indicator
comes on.
■Parking Brake1Brake System
When you depress the brak e pedal, you may hear a
whirling sound from the engine compartment. This is
because the brake system is in operation, and it is
normal.
1 Parking Brake
You may hear the electric parking brake system
motor operating from the re ar wheel area when you
apply or release the parking brake. This is normal.
The brake pedal may slightly move due to the electric
parking brake system opera tion when you apply or
release the parking brake. This is normal.
You cannot apply or release the parking brake if the
battery goes dead. 2 Jump Starting P. 562
If you pull up and hold the electric parking brake
switch while driving, the brakes on all four
wheels are applied by the VSA ® system until the
vehicle come to a stop. The electric parking
brake then applies, and the switch should be
released.
