uuWhen Driving uBSI (Blind Spot Information)*
Driving
Press the BSI OFF button until you hear a beep to turn on and off the system. A
message on the multi-information display appears for five seconds and indicates
that the system is on or off.
When BSI is off, the BSI indicator in the in strument panel stays on.
BSI stays off next time you sta rt the engine, if you turned it off the last time you drive
the vehicle.
■BSI On and Off1 BSI (Blind Spot Information)*
The BSI alert indicator may not come on under
following conditions:
•A vehicle does not stay in the alert zone for more
than two seconds.
•A vehicle is parked in a side lane.•The speed difference between your vehicle and the
vehicle you are passing is greater than 6 mph (10 km/h).
•An object not detected by the radar sensors
approaches or passes your vehicle.
Turn the system off when towing a trailer. The system
does not work properly for the following reasons:
•The added mass tilts the vehicle and changes the radar coverage.•The trailer itself can be detected by the radar sensors,
causing the BSI alert indicators to come on.
BSI may be adversel y affected when:•Objects (guard rails, poles, trees, etc,.) are detected.•An object that does not reflect radio waves well,
such as a motorcycle, is in the alert zone.
•Driving on a curved road.•A vehicle is moving from a far lane to the adjacent lane.•The system picks up external electrical interference.•The rear bumper or the sensors have been improperly
repaired or the rear bumper has been deformed.
•The orientation of the sensors has been changed.•In bad weather (Heavy rain, snow, and fog).
For a proper BSI use:
•Always keep the rear bu mper corner area clean.•Do not cover the rear bumper corner area with
labels or stickers of any kind.
•Take your vehicle to a dealer if you need the rear bumper
corner area or the radar sensors to be repaired, or the
rear bumper corner area is strongly impacted.

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.

uuWhen Driving uTire Pressure Monitoring System (TPM S) - Required Federal Explanation
Driving
Tire Pressure Monitoring System (TPMS) - Required
Federal Explanation
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle placard
or tire inflation pressure label.
(If your vehicle has tires of a diffe rent size than the size indicated
on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with
a tire pressure monitoring system (TPMS) that illuminates a low
tire pressure telltale
when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pr essure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate
them to the proper pressure.
Driving on a significantly under-inflated tire causes the tire to
overheat and can lead to tire fail ure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.

251
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.

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.
