The lane change signals will blink 3,
5 or 7 times.
You can activate or deactivate the
One Touch Turn Signal function or
choose the number of blinking (3, 5,
or 7) from the User Settings Mode
(Light) on the LCD display (if
equipped with supervision cluster).
For more details, refer to the "LCD
Display" section in this chapter.
Battery saver function
The purpose of this feature is to help
prevent the battery from being dis-
charged. The system automatically
turns off the parking lamp when the
key is removed (remote key) or when
the driver turns the engine off (smart
key) and opens the driver-side door.
With this feature, the parking lamps
will turn off automatically if the driver
parks on the side of road at night.
If necessary, to keep the lamps on
when the engine is turned off, perform
the following:
1) Open the driver-side door.
2) Turn the parking lamps OFF andON again using the light switch on
the steering column.
Headlamp delay function (if equipped)
If the key is removed from the ignition
switch or placed in the ACC position
or the LOCK/OFF position with the
headlamps ON, the headlamps
(and/or parking lamps) remain on for
about 5 minutes. However, if the dri-
ver’s door is opened and closed, the
headlights are turned off after 15
seconds. Also, with the engine off if
the driver's door is opened and
closed, the headlamps (and/or park-
ing lamps) are turned off after 15
seconds.
The headlamps (and/or parking
lamps) can be turned off by pressing
the lock button on the remote key or
smart key twice or turning the light
switch to the OFF or AUTO position.
You can activate or deactivate the
Headlamp Delay function from the
User Settings Mode (Light) on the
LCD display (if equipped with super-
vision cluster).
For more details, refer to the "LCD
Display" section in this chapter. If the driver exits the vehicle
through another door besides the
driver door, the battery saver func-
tion does not operate and the
headlamp delay function does not
turn OFF automatically.
This may cause the battery to dis-
charge. To avoid battery dis-
charge, turn OFF the headlamps
manually from the headlamp
switch before exiting the vehicle.

System Description
Blind-Spot Collision Warning(BCW)
The Blind-Spot Collision Warning
(BCW) system uses radar sensors in
the rear bumper to monitor and warn
the driver of an approaching vehicle
in the driver's blind spot area.
1) Blind-Spot Area
The blind spot detection range varies
relative to vehicle speed.
Note that if your vehicle is traveling
much faster than the vehicles around
you, the warning will not occur. 2) Closing at high speed
The Lane Change Assist feature will
alert you when it detects a vehicle is
approaching in an adjacent lane at a
high rate of speed. If the driver acti-
vates the turn signal when the sys-
tem detects an oncoming vehicle,
the system sounds an audible alert.

Maintenance
Owner Maintenance Schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in the enginecoolant reservoir.
Check the windshield washer fluid level.
Check for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound ofthe exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
Notice if your vehicle constantly turns slightly or "pulls" to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
If any slipping or changes in the operation of your transmission
occurs, check the transmission
fluid level.
Check the transmission P (Park) function.
Check the parking brake. Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the brake lights,
turn signals and hazard warning
flashers.
Check the inflation pressures of all tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.
