pressed.
If the battery of the vehicle is discharged,
the push-button ignition switch cannot be
turned from the LOCK position.
Some indicators and warnings for operation
are displayed on the vehicle information
display between the speedometer and tach-
ometer. (See “Vehicle information display”
(P.2-20).)

WARNING
.Be sure the parking brake is fully
released before driving. Failure to do
so can cause brake failure and lead to
an accident.
. Do not release the parking brake
from outside the vehicle.
. Do not use the gear shift in place of
the parking brake. When parking, be
sure the parking brake is fully en-
gaged.
. To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not
leave children, people who require the
assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly
become high enough to cause a sig-
nificant risk of injury or death to
people and pets.
SPA2331
To apply: Fully depress the parking brake
pedal.
To release:
1. Firmly apply the foot brake
.
2. Depress the parking brake pedal
and
the parking brake will be released.

WARNING
Failure to follow the warnings and
instructions for proper use of the LDW
and LDP (if so equipped) systems could
result in serious personal injury or death.
.The LDW and LDP (if so equipped)
systems will not steer the vehicle or
prevent loss of control. It is the
driver’s responsibility to stay alert,
drive safely, keep the vehicle in the
traveling lane, and be in control of
the vehicle at all times.
. The LDP system (if so equipped) may
activate if you change lanes without
first activating your turn signal or,
for example, if a construction zone
directs traffic to cross an existing
lane marker. If this occurs, you may
need to apply corrective steering to
complete your lane change.
. Because the LDP system (if so
equipped) may not activate under
the road, weather, and lane marker
conditions described in this section, it
may not activate every time your
vehicle begins to leave its lane and
you will need to apply corrective
steering.

mately 45 MPH (70 km/h) and the lane
markings are clear.
If the vehicle approaches either the left or
right side of the traveling lane, the LDW
indicator on the vehicle information display
will flash and a warning chime will sound.
NOTE:
The LDW system is not designed to warn
when you operate the lane change signal
and change traveling lanes in the direction
of the signal. (The LDW system will become
operable again approximately 2 seconds
after the lane change signal is turned off.)

LDP SYSTEM OPERATION (if so
equipped)
The LDP system operates above approxi-
mately 45 MPH (70 km/h) and the lane
markings are clear.
If the vehicle approaches either the left or
right side of the traveling lane, the LDW
indicator on the vehicle information display
will flash and a warning chime will sound.
Then, the LDP system will automatically
apply the brakes for a short period of time to
help assist the driver to return the vehicle to
the center of the traveling lane.
NOTE:
. The LDP system is not designed to work
when you operate the lane change signal
and change traveling lanes in the direc-
tion of the signal. (The LDP system will
become operable again approximately 2
seconds after the lane change signal is
turned off.)
. The LDP braking assist will not operate
or will stop operating and only a warn-
ing chime will sound under the following
conditions.
— When the brake pedal is depressed.
— When the steering wheel is turned as
far as necessary for the vehicle to
change lanes. —
When the accelerator pedal is de-
pressed while brake control assist is
provided.
— When the Intelligent Cruise Control
(ICC), Distance Control Assist (DCA),
Blind Spot Intervention
®(BSI), Blind
Spot Warning (BSW), Predictive For-
ward Collision Warning (PFCW) or
Forward Emergency Braking (FEB)
warnings sound.
— When the hazard warning flashers
are operated.
— When driving on a curve at a high
speed.
. While the LDP system is operating, you
may hear a sound of brake operation.
This is normal and indicates that the
LDP system is operating properly.

— On roads where the discontinuedlane markers are still detectable.
— On roads where there are sharp curves.
— On roads where there are sharply contrasting objects, such as sha-
dows, snow, water, wheel ruts,
seams or lines remaining after
road repairs. (The LDW and LDP
(if so equipped) systems could
detect these items as lane mar-
kers.)
— On roads where the traveling lane merges or separates.
— When the vehicle’s traveling di- rection does not align with the
lane marker.
— When traveling close to the ve- hicle in front of you, which ob-
structs the lane camera unit
detection range.
— When rain, snow or dirt adheres to the windshield in front of the
lane camera unit.
— When the headlights are not bright due to dirt on the lens or
if the aiming is not adjusted
properly. — When strong light enters the lane
camera unit. (For example, the
light directly shines on the front
of the vehicle at sunrise or sun-
set.)
— When a sudden change in bright- ness occurs. (For example, when
the vehicle enters or exits a tunnel
or under a bridge.)
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.

BSW SYSTEM OPERATION
The BSW system operates above approxi-
mately 20 MPH (32 km/h).
If the radar sensors detect a vehicle in the
detection zone, the side indicator light
illuminates.
If the turn signal is then activated, the
system chimes (twice) and the side indicator
light flashes. The side indicator light con-
tinues to flash until the detected vehicle
leaves the detection zone.
NOTE:
.The side indicator light illuminates for a
few seconds when the ignition switch is
placed in the ON position.
. The brightness of the side indicator light
is adjusted automatically depending on
the brightness of the ambient light.
. If a vehicle comes into the detection zone
after the driver activates the turn
signal, then only the side indicator light
flashes and no chime sounds. For addi-
tional information, refer to “BSW sys-
tem limitations” (P.5-35).
