■VSA ® On and Off1 VSA ® (Vehicle Stability Assist), aka ESC (Electronic Stability
Control), System
Without VSA ®, your vehicle will have normal braking
and cornering ability, but it will not have VSA ®
traction and stability enhancement.
In certain unusual condition s when your vehicle gets
stuck in shallow mud or fresh snow, it may be easier
to free it with the VSA ® temporarily switched off.
When the VSA ® system is off, the traction control
system is also off. You sh ould only attempt to free
your vehicle with the VSA ® off if you are not able to
free it when the VSA ® is on.
Immediately after freeing yo ur vehicle, be sure to
switch VSA ® on again. We do not recommend driving
your vehicle with the VSA ® and traction control
systems switched off.
If the low tire pressure/T PMS indicator comes on or
blinks, the VSA ® system comes on automatically. In
this case, you cannot turn the system off by pressing
the button.
You may hear a motor sound coming from the
engine compartmen t while system checks are being
performed immediately after starting the engine or
while driving. This is normal.

uuWhen Driving uTPMS (Tire Pressure Monitoring System)
Driving
TPMS (Tire Pressure Monitoring System)
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 mu lti-information display.
To select the tire pressure monitor, turn the
ignition switch to ON
w*1 and press the /
button until you see the tire pressure screen.
If all the tire pressures are normal, TIRE
PRESSURE OK and the pressure of all four
tires will be displayed.
The pressure for each tire is displayed in PSI
(U.S.) or kPa (Canada).
*1: Models with the keyless access system have an ENGINE START/STOP button
instead of an ignition switch.
■Tire Pressure Monitor
1 TPMS (Tire Pressure Monitoring System)
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. 337
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/TPM S indicator will not come
on as a result of over inflation.
1 Tire Pressure Monitor
The pressure displayed on the multi-information
display can be slightly different from the actual
pressure as measured by a gauge. If there is a
significant difference between the two values, or if
the low tire pressure/TPMS indicator and the message
on the multi-information display do not go off after
you have inflated the tire to the specified pressure,
have the system checked by a dealer.
TPMS ERROR may appear if you drive with the
compact spare tire, or ther e is a problem with the
TPMS.

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

uuBraking uABS (Anti-lock Brake System)
Driving
ABS (Anti-lock Brake System)
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) sy stem, which is part of the ABS, also
balances the front-to-rear braking distri bution according to vehicle loading.
You should never pump th e brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pedal. 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.
When the vehicle speed goes under 6 mph (10 km/h), the ABS stops.
■ABS1 ABS (Anti-lock Brake System)
NOTICEThe 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 no t affected, there is a
possibility of the ABS not operating. Have the 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, your vehicle may need more
stopping distance than a vehicle without the ABS:
•When driving on rough road surfaces, including
when driving on uneven surfaces, such as gravel or
snow.
•When tire chains are installed.
You may hear a motor sound coming from the
engine compartmen t while system checks are being
performed immediately after starting the engine or
while driving. This is normal.

uuBraking uCMBSTM (Collision Mitigation Braking SystemTM)*
Continued
Driving
CMBSTM (Collision Mitigation Braking SystemTM)*
Can assist you when there is a possibility of your vehicle colliding with the vehicle in
front of yours. The CMBSTM is designed to alert you, then reduce your vehicle speed
when a possible collision is likely unavoidable to help minimize collision severity.
■How the system works
■When the system activates
1 CMBSTM (Collision Mitigation Braking SystemTM)*
Important Safety Reminder
The CMBSTM is designed to reduce the severity of an
unavoidable collision. It do es not prevent collision nor
stop the vehicle automatically. It is still your
responsibility to operate th e brake pedal and steering
wheel appropriately according to the driving
conditions.
The CMBS
TM may not activate or may not detect a
vehicle in front of your vehicle under the following
conditions:
•The distance 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 ra pidly and approach the
vehicle ahead of you at high speed.
•The vehicle ahead of you is a motorcycle or other
small vehicle.
•A vehicle suddenly crosses in front of you.•When you drive on a curved or winding road that
makes it difficult for the se nsor to properly detect a
vehicle in front of you.
•When there are pedestrians or animals in front of
your vehicle.
A radar sensor starts to detect if there is a vehicle in front of you when your vehicle
speed is above 10 mph (15 km/h).
The radar sensor is under the
emblem in the front grille.
The CMBS
TM activates when the speed difference betw een the two vehicles
becomes more than 10 mph (15 km/h ) with a chance of a collision.
A visual alert or a combination of a visual
alert and an audible alert for a possible
collision.
