• The lane in which you are driving has dete ctable lane markers on both sides, and
your vehicle is in the center of the lane.
• The vehicle speed is between 45 and 90 mph (72 and 145 km/h).
• You are driving 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 to activate the system
1.Press the MAIN button.
u The LKAS is on in the multi-information
display.
The system is ready to use.
2. Press the LKAS button.

uuWhen Driving uAgile Handling Assist
Driving
Agile Handling Assist
Lightly brakes each of the front and rear wheels, as needed, when you turn the
steering wheel, and helps support the vehi cle’s stability and performance during
cornering.
Precision All-Wheel SteerTM (P-AWS ®) System
Monitors road conditions while you are dr iving. In response to current driving
conditions, the system automatically makes slight adjustment to the relative rear
wheel toe settings to help enhance vehicle control and stability.
1 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 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.

The Precision All-Wheel Steer
TM (P-AWS ®) System
cannot enhance vehicle cont rol and 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.
The toe setting of the rear wheels may get stuck in a
non-centered se tting if the system malfunctions
while driving. This can caus e the vehicle to pull to a
side even as you keep the steering wheel in the
center position. If this occurs, the system
automatically limits the vehicle speed to a maximum
of 50 mph (80 km/h). Reduce your speed and be
extra cautious, as handling may be difficult. Go to a
dealer immediately.

Braking
Brake System
Use the parking brake to keep the vehicle stationary when parked. You can
manually apply and release, or automatically release it.
■Manual operations
Use the electric parking brake switch to apply or release the brake. Manually
releasing the parking brake using the switch helps your vehicle start slowly and
smoothly when facing down hill on steep hills.
■To apply manually
Pull the electric parkin g brake switch up gently
and securely.
u The electric parking brake indicator
comes on.
■To release manually
1. Depress the brake pedal.
2. Press the electric parking brake switch.
u The electric parking brake indicator goes
off.
■Parking Brake1Parking Brake
You may hear the electric parking brake system
operating when you apply or release the parking
brake, or set the power mode to OFF. 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 br ake. This is normal.
You cannot apply or release the parking brake if the
battery goes dead. 2 Jump Starting P. 512

uuBraking uBrake System
404
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 th e 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. 408
2 Anti-lock Brake System (ABS) P. 407
■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 vibration 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.

Keeps the brake applied after releasing the brake pedal until the accelerator pedal is
pressed. You can use this system while the vehicle is temporarily stopped, such as
when you stop at a traffic light.
■Automatic Brake Hold1 Automatic Brake Hold
3WARNING
Activating the automatic brake hold system
on steep hills or slippery roads may still
allow the vehicle to move if you remove
your foot from the brake pedal.
If a vehicle unexpectedly moves, it may
cause a crash resulting in serious injury or
death.
Never activate the automatic brake hold
system or rely on it to keep a vehicle from
moving when stopped on a steep hill or
slippery roads.
3WARNING
Using the automatic brake hold system to
park the vehicle may result in the vehicle
unexpectedly moving.
If a vehicle moves unexpectedly, it may
cause a crash, resulting in serious injury or
death.
Never leave the vehicle when braking is

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, and helps you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distribu tion (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distribution according to vehicle loading.
You should never pu mp the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.”
■ABS operation
The brake pedal may pulsate slightly when the ABS is working. Keep holding the
pedal firmly down. On dry pavement, you w ill need to press on the brake pedal very
hard before the ABS activates. However, you may feel the ABS activate immediately
if you are trying to stop on snow or ice.
When the vehicle speed goes unde r 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correctly if you use an
incorrect tire type and size.
When the ABS indicator comes on while driving,
there may be a problem with the system.
While normal braking is not affected, there is a
possibility of the ABS not operating. Have your
vehicle checked by a dealer immediately.
The ABS does not reduce the ti me or distance it takes
to stop the vehicle. It only helps with steering control
during hard braking.
In the following cases, yo ur vehicle may need more
stopping distance than a vehicle without the ABS:
•When driving on rough road surfaces, including
when driving on uneven surf aces, such as gravel or
snow.
•When tire chains are installed.
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after starting the engine or
while driving. This is normal.
