5-22Starting and driving
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.
3. Before driving, be sure the brake warning light goes out.
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.

— 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.
SYSTEM TEMPORARILY UNA-
VAILABLE
Condition A
The warning and assist functions of the
LDW and LDP (if so equipped) systems are
not designed to work under the following
conditions:
.When you operate the lane change signal
and change the traveling lanes in the
direction of the signal. (The LDP system
(if so equipped) will be deactivated for
approximately 2 seconds after the lane
change signal is turned off.)
. When the vehicle speed lowers to less
than approximately 45 MPH (70 km/h). .

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).

TURNING THE BSW SYSTEM ON/
OFF
The warning systems switchis used to
turn on and off the BSW system when it is
activated using the settings menu on the
lower display
. See “How to enable/disable
the BSW system” (P.5-34). When the warn-
ing systems switch

will turn on
and off the Lane Departure Warning (LDW)
and BSW systems at the same time.
HOW TO ENABLE/DISABLE THE
BSW SYSTEM
The BSW system can be turned off perma-
nently using the lower display.

BSI SYSTEM OPERATION
The BSI system operates above approxi-
mately 37 MPH (60 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.
If the BSI system is ON and your vehicle
approaches a lane marker while another
vehicle is in the detection zone, the system
chimes (three times) and the side indicator
light flashes. Then the BSI system slightly
applies the brakes to help return the vehicle
back to the center of the driving lane. The
BSI system operates regardless of turn
signal usage.
NOTE:
.Warning and system application of the
brakes will only be activated if the side
indicator light is already illuminated
when your vehicle approaches a lane
marker. If another vehicle comes into
the detection zone after your vehicle has
crossed a lane marker, no warning or
system application of the brakes will be
activated. (See “BSI driving situations” (P.5-46).)
. The BSI system is typically activated
earlier than the Lane Departure Preven-
tion (LDP) system when your vehicle is
approaching a lane marker.
