Cruise Control*
Maintains a constant vehicle speed with out having to keep your foot on the
accelerator. Use cruise control on freeways or open roads where you can travel at a
constant speed with little ac celeration or deceleration.1Cruise Control*
It may not be possible to maintain a constant speed
when driving uphill or downhill.
When not using cruise control:
Turn off cruise control by pressing the CRUISE
button.
3WARNING
Improper use of the cruise control can lead
to a crash.
Use the cruise control only when traveling
on open highways in good weather.
■Shift positions for cruise control:
In ( D or (S Always keep sufficient distance
between you and the vehicle in
front of you.

ACC (Adaptive Cruise Control)*
Maintains a constant vehicle speed and a safe distance between your vehicle and the
vehicle ahead of you without having to keep your foot on the brake pedal or
accelerator.1 ACC (Adaptive Cruise Control)*
Important Safety Reminder
As with any system, th ere are limits to ACC.
Inappropriate use of ACC can result in a serious
accident. Use the brake pedal whenever necessary,
and always keep a safe distance between your vehicle
and other vehicles.
The radar sensor for ACC is shared with the CMBS
TM
(collision mitigation braking systemTM).

SystemTM)* P. 257
3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when traveling on open
highways in good weather.When to use
■Vehicle speed for adaptive cruise control:

uuWhen Driving uACC (Adaptive Cruise Control)*
238
Driving
■There is no vehicle ahead
Your vehicle cruises at the set speed.
■A vehicle ahead is within ACC range and going slower than the set speed
Your vehicle slows down, and maintains the same speed as the speed of the vehicle
ahead.
■A vehicle ahead is within ACC range and going at a steady speed
Your vehicle follows the vehicle ahead of it, keeping a constant distance, without
going beyond the set speed.
■A vehicle ahead goes out of range
ACC accelerates your vehicle to the set speed, and then maintains it.
■When you depress the accelerator pedal
You can temporarily increase the vehicle speed . In this case, there is no audible or
visual alerts even if a vehicle is in ACC range.
ACC stays on unless you cancel it. Once you release the accelerator pedal, the
system resumes the set speed.
1 When in Operation
Limitations
Use the brake pedal to mainta in a safe distance with
other vehicles in the follo wing cases. ACC may not
work properly when:
•Vehicles ahead of you are going slower than 13
mph (20 km/h) or vehicles are parked.
•Motorcycles or other small vehicles are ahead of
you.
ACC may momentarily apply brakes or sounds a beep
against a vehicles beside you or even a building
beside you if:
•You drive at a sudden curve or on a narrow road.•You abruptly move the steering wheel.•You are in an unusual position within your lane.

uuWhen Driving uSH-AWD ® (Super Handling-All Wheel DriveTM)
Driving
SH-AWD ® (Super Handling-All Wheel DriveTM)
The system controls and transfers varying amounts of engine torque to each wheel
in accordance with the driving conditions.
SH-AWD® helps to enhance driving stability, and lets you handle situations like
slippery surfaces, such as snow, sand, mud, and steep hill, better than when driving
with two wheel drive. However, the system does not help to enhance braking. Be
precautious about the following:
• It is still your responsibility to drive sa fely when you steer, accelerate, and apply
brakes.
• Leave a sufficient margin when braking on slippery surfaces.1SH-AWD ® (Super Handling-All Wheel DriveTM)
NOTICEAvoid continuously driving in sand or mud where a
wheel is likely to spin out, and do not drive once the
SH-AWD ® indicator starts blinking. Driving
continuously under such conditions can damage the
system’s torque distribution unit.
Do not drive through deep water.
The 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.

uuWhen Driving uTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Driving
Please note that the TPMS is no t a substitute for proper tire
maintenance, and it is the driv er’s responsibility to maintain
correct tire pressure, even if u nder-inflation has not reached the
level to trigger illumination of th e TPMS low tire pressure telltale.
Your vehicle has also been equi pped with a TPMS malfunction
indicator to indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the syst em detects a malfunction, the
telltale will flash for approximately one minute and then remain
continuously illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction te lltale after replacing one or
more tires or wheels on your vehicle to ensure that the
replacement or alternate tire s and wheels allow the TPMS to
continue to function properly.

Braking
Brake System
Use the parking brake to keep the vehicle stationary when parking.
To apply:
Push the pedal down with your foot.
To release:
Push the pedal again.
■Parking Brake1 Parking Brake
NOTICERelease the parking brake fully before driving. The
rear brakes and axle can be damaged if you drive
with the parking brake applied.
If you start driving without fully releasing the parking
brake, a buzzer sounds as a warning, and RELEASE
PARKING BRAKE appears on the multi-information
display.
Always apply the parking brake when parking.
To prevent the parking brake from freezing when the
outside temperature is extremely cold, do not apply
it, but do the following:
Put the shift lever in
( P, then use a block or other
wheel chock to stop the wheels from turning.

uuBraking uBrake System
254
Driving
Your vehicle is equipped with disc brakes at all four wheels. A power assist helps
reduce the effort needed on the brake pedal. The brake assist system increases the
stopping force when you depress the brake pe dal hard in an emergency situation.
The anti-lock brake system (ABS) helps you re tain steering control when braking very
hard.

■Foot Brake1Foot Brake
Check the brakes after driv ing 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 metallic friction sound when
applying the brakes, the brake pads need to be
replaced. Have the vehicl e checked by a dealer.
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 pedal 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 confuse drivers behind you.
