Agile Handling Assist
Lightly brakes selective 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.

Driving
Adaptive Cruise Control (ACC) with Low Speed Follow
Helps maintain a constant vehicle speed a nd a set following-interval behind a vehicle
detected ahead of yours and, if the detect ed vehicle comes to a stop, can decelerate
and stop your ve hicle, without yo u having to keep your foot on the brake or the
accelerator.
When ACC with Low Speed Follow slows your 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.
The radar sensor for ACC with Low Speed Follow is
shared with the collision mitigation braking system
TM
(CMBSTM).
2 Collision Mitigation Braking SystemTM
(CMBSTM) P. 453
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.
■Shift position for ACC with Low Speed Follow: In ( D or (S.
The radar sensor is in
the lower bumper.
Be careful not to have
the radar sensor cover
strongly impacted.
The camera is
located behind
the rearview
mirror.

Use the parking brake to keep the vehicle stationary when parked. When the
parking brake is applied, you can manually or automatically release it.
■To apply
The electric parking brake can be applied any
time the vehicle has battery, no matter which
position the ignition switch
*1 is in.
Pull the electric parking brake switch up gently
and securely. u The indicator in th e switch comes on.
u The parking brake and brake system
indicator (red) comes on.
■To release
The ignition switch must be ON

to release the electric parking brake.
1. Depress the brake pedal.
2. Press the electric parking brake switch.
u The indicator in th e switch goes off.
u The parking brake and brake system
indicator (red) goes off.
Manually releasing the parking brake using
the switch helps your ve hicle start slowly and
smoothly when facing down hill on steep hills.
*1: Models with the smart entry system have an ENGINE START/STOP button instead of an
ignition switch.
■Parking Brake1 Parking Brake
You may hear the electric parking brake system
motor operating from the re ar wheel area when you
apply or release the parki ng 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 br ake. This is normal.
You cannot apply or release the parking brake if the
12-volt battery goes dead. 2 If the Battery Is Dead P. 583
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
comes to a stop. The electric parking brake then
applies, and the switch should be released.
In the following situations, the parking brake
automatically operates.
•When your vehicle is stopped with the automatic
brake hold system activated for more than 10
minutes.
•When the driver’s seat belt is unfastened while
your vehicle is stopped and the brake hold system
is applied.
•When the engine is turned off while the brake hold
system is applied.
•When there is a problem with the brake hold
system while brake hold is applied.
•When your vehicle is stopped for more than 10
minutes while ACC with Low Speed Follow is
activated.

uuBraking uBrake System
496
Driving
Your vehicle is equipped with disc brakes at all four wheels. A vacuum power assist
helps to 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 an ti-lock brake system (ABS) helps you retain steering
control when braking very hard.
2 Brake Assist System P. 500
2 Anti-lock Brake System (ABS) P. 499
■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 brake 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
speed position.
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.
