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.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.

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. 657
Tire pressure checked and inflated in:
•Warm weather can beco me 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 ti re that you
are adjusting using audibl e 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.

uuWhen Driving uTire Pressure Monitoring System (TPMS) with Tire Fill Assist
Driving
To select the tire pressure monitor, set the power
mode to ON, and roll the multi-function
steering-wheel controls until you see the tire
pressure screen.
The pressure for each tire is displayed in psi
(U.S.) or kPa (Canada).
Tire Pressures Low is displayed when a tire
has significantly low pressure. The specific tire
is displayed on the screen.
■Tire Pressure Monitor1 Tire Pressure Monitor
The pressure displayed on the MID can be slightly
different from the actual pr essure as measured by a
gauge. If there is a signifi cant difference between the
two values, or if the low tire pressure/TPMS indicator
and the message on the MID do not go off after you
have inflated the tire to the specified pressure, have
the system checked by a dealer.
Tire Pressure Monitor Problem may appear if you
drive with the compact spare tire, or there is a
problem with the TPMS.

Braking
Brake System
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
power mode the vehicle is in.
Press the electric parking brake switch gently
and securely. u The electric parking brake indicator
comes on.
■Parking Brake1Parking 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, 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. 649
If you press 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 (at which point the
electric parking brake is applied) or the switch is
released.

uuBraking uBrake System
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 the brake pedal hard in an emergency
situation. The anti-lock brake system (ABS) helps you retain steering control when
braking very hard.

■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 vibr ation 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.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, an d helps you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distribution (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distri bution according to vehicle loading.
You should never pump 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 will 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.
ABS may activate when you depress the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surfaces, such as potholes, cracks, manholes, etc.
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 correc tly if you use a tire of
the wrong size or type.
If the ABS indicator comes on while driving, there
may be a problem with the system.
While normal braking will not be affected, there is a
possibility that the ABS will not operating. Have your
vehicle checked by a dealer immediately.
The ABS is not designed for the purpose of reducing
the time or distance it takes for a vehicle to stop: It is
designed to limit brake lo ckup which can lead to
skidding and loss of steering control.
In the following cases, yo ur vehicle may need more
distance to stop than a vehicle without the ABS:
•You are driving on rough or uneven road surfaces,
such as gravel or snow.
•The tires are equipped with snow chains.
The following may be observed with the ABS system:
•Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the
engine has been started and while vehicle is
accelerates.
•Brake pedal and/or the ve hicle body vibration when
ABS activates.
These vibrations and sou nds are normal to ABS
systems and are no cause for concern.

Brake Assist System
Designed to assist the driver by generati ng greater braking force when you depress
the brake pedal hard during emergency braking.
■Brake assist system operation
Press the brake pedal firmly for more powerful braking.
When brake assist operates, the pedal may wiggle slightly and an operating noise
may be heard. This is normal. Keep holding the brake pedal firmly down.
