CAUTION
Use the headlights with the engine run-
ning to avoid discharging the vehicle
battery.
Autolight system
The autolight system allows the headlights
to turn on and off automatically. The auto-
light system can:∙ Turn on the headlights, front parking, tail, license plate and instrument panel
lights automatically when it is dark.
∙ Turn off all the lights when it is light.
∙ Keep all the lights on for a period of time af ter you place the ignition switch in the
OFF position and all doors are closed. NOTE:
Autolight activation sensitivity and the
time delay for autolight shutoff can be
adjusted. For additional information, re-
fer to “Vehicle information display ” in
this section.
To turn on the autolight system:
1. Turn the headlight switch to the AUTO position
1.
2. Turn the ignition switch to ON.
3. The autolight system automatically turns the headlights on and off.
Initially, if the ignition switch is placed in the
OFF position and a door is opened and lef t
open, the headlights remain on for a period
of time. If another door is opened while the
headlights are on, then the timer is reset.
To turn the autolight system off, turn the
switch to the OFF (if so equipped),

Be sure you do not put anything on top
of the autolight sensor located in the top
side
1of the instrument panel. The au-
tolight sensor controls the autolight; if it
is covered, the autolight sensor reacts as
if it is dark out and the headlights will
illuminate. If this occurs while parked
with the engine off and the ignition
switch placed in the ON position, your
vehicle’s battery could become dis-
charged.

WARNING
∙ Your vehicle’s engine should beturned off while programming the
HomeLink® Universal Transceiver. For
additional information, refer to
“Push-button ignition switch” in the
“Starting and driving” section of this
manual. Do not breathe exhaust
gases; they contain colorless and
odorless carbon monoxide. Carbon
monoxide is dangerous. It can cause
unconsciousness or death.
∙ Do not use the HomeLink® Universal Transceiver with any garage door
opener that lacks safety stop and re-
verse features as required by federal
safety standards. (These standards
became effective for opener models
manufactured af ter April 1, 1982.) A
garage door opener which cannot de-
tect an object in the path of a closing
garage door and then automatically
stop and reverse does not meet cur-
rent federal safety standards. Using a
garage door opener without these
features increases the risk of serious
injury or death. ∙ During the programming procedure
your garage door or security gate will
open and close (if the transmitter is
within range). Make sure that people
or objects are clear of the garage door,
gate, etc., that you are programming.
PROGRAMMING HOMELINK®
If you have any questions or are having
difficulty programming your HomeLink®
buttons, refer to the HomeLink® web site at:
www.homelink.com or call 1-800-355-3515.
NOTE:
Place the ignition switch in the ON posi-
tion (without starting the engine) when
programming HomeLink®. It is also rec-
ommended that a new battery be placed
in the hand-held transmitter of the de-
vice being programmed to HomeLink®
for quicker programming and accurate
transmission of the radio frequency. 1. Position the end of your hand-held
transmitter 1–3 in (2–8 cm) away from
the HomeLink® surface, keeping the
HomeLink® indicator light
1in view.

NOTE:∙ Request switches for all doors and
trunk can be deactivated when the
Ext. Door Switch feature is switched
to OFF using the “Vehicle Settings”
menu on the vehicle information, re-
fer to “Vehicle information display ” in
the “Instruments and controls” sec-
tion of this manual.
∙ Doors lock with the door handle re-
quest switch while the ignition switch
is not in the LOCK position. ∙
Doors lock by pushing the driver’s
side door handle request switch while
any door is open. However, the corre-
sponding door locks with the me-
chanical key even if any door is open.

The non-viewable area2is highlighted in
yellow for several seconds af ter the bird’s-
eye view is displayed. It will be shown only
the first time af ter the ignition switch is
placed in the ON position.
In addition, the non-viewable corners are
displayed in red and blink for the first 3 sec-
onds
3to remind the driver to be cau-
tious. Predicted course lines
4indicate the pre-
dicted course when operating the vehicle.
The predicted course lines will be displayed
on the monitor when the steering wheel is
turned. The predicted course lines will
move depending on how much the steer-
ing wheel is turned and will not be dis-
played while the steering wheel is in the
neutral position.
When the monitor displays the front view
and the steering wheel turns about 90 de-
grees or less from the neutral position, the
two green predicted course lines are
shown in front of the vehicle.
When the steering wheel turns about 90
degrees or more, one green predicted
course line is shown in front of the vehicle
and the other predicted course line is
shown at the side of the vehicle.
When the monitor displays the rear view,
the predicted course lines are shown at the
back of the vehicle.

Additional information:∙ When replacing a wheel without the TPMS such as the spare tire, the TPMS
does not monitor the tire pressure of
the spare tire.
∙ The TPMS will activate only when the vehicle is driven at speeds above
16 mph (25 km/h). Also, this system may
not detect a sudden drop in tire pres-
sure (for example, a flat tire while driv-
ing).
∙ The low tire pressure warning light does not automatically turn off when the tire
pressure is adjusted on all four tires. Af-
ter all four tires are inflated to the rec-
ommended pressure, the vehicle must
be driven at speeds above 16 mph
(25 km/h) to activate the TPMS and turn
off the low tire pressure warning light.
Use a tire pressure gauge to check the
tire pressure.
∙ The “Tire Pressure Low - Add Air” warn- ing appears in the vehicle information
display when the low tire pressure
warning light is illuminated and low tire
pressure is detected. The “Tire Pressure
Low - Add Air” warning turns off when
the low tire pressure warning light turns
off. ∙ The “Tire Pressure Low - Add Air” warn-
ing appears each time the ignition
switch is placed in the ON position as
long as the low tire pressure warning
light remains illuminated.
∙ The “Tire Pressure Low - Add Air” warn- ing does not appear if the low tire pres-
sure warning light illuminates to indi-
cate a TPMS malfunction.
∙ Tire pressure rises and falls depending on the heat caused by the vehicle’s op-
eration and the outside temperature.
Do not reduce the tire pressure af ter
driving because the tire pressure rises
af ter driving. Low outside temperature
can lower the temperature of the air
inside the tire which can cause a lower
tire inflation pressure. This may cause
the low tire pressure warning light to
illuminate. If the warning light illumi-
nates, check the tire pressure for all four
tires.
∙ The Tire and Loading Information label is located in the driver’s door opening. ∙ You can also check the tire pressure of
all tires (except the spare) on the vehicle
information display screen. The order of
the tire pressure figures displayed on
the screen corresponds with the actual
order of the tire position.
For additional information, refer to “Low tire
pressure warning light” in the “Instruments
and controls” section, “Tire Pressure Moni-
toring System (TPMS)” in the “In case of
emergency” section and “Tire pressure” in
the “Do-it-yourself ” section of this manual.
