DOORS
Manual Door Locks
Front and rear doors may be locked by moving the lock knob
down. The lock knobs will unlock when the interior handle
is used to open the doors.Door Lock Knob
Front doors may be opened with the inside door handle
without lifting the lock knob. Doors locked before closing will remain locked when closed.
The emergency key will unlock the driver door lock on your
vehicle.
WARNING!
• Do not leave children or animals inside parked vehicles in hot weather. Interior heat build-up may cause
serious injury or death.
• For personal security and safety in the event of a colli -
sion, lock the vehicle doors as you drive as well as
when you park and leave the vehicle.
• Before exiting a vehicle, always shift the automatic transmission into PARK, apply the parking brake, turn
the vehicle OFF, remove the key fobs from vehicle, and
lock the vehicle.
• Never leave children alone in a vehicle, or with access to an unlocked vehicle. Leaving children in a vehicle
unattended is dangerous for a number of reasons. A
child or others could be seriously or fatally injured.
Children should be warned not to touch the parking
brake, brake pedal or the gear selector.2

NOTE:
The mist feature does not activate the washer pump; there-
fore, no washer fluid will be sprayed on the windshield. The
wash function must be used in order to spray the windshield
with washer fluid.
Rain Sensing Wipers — If Equipped
This feature senses rain and snowfall on the windshield and
automatically activates the wipers for the driver. The feature
is especially useful for road splash or overspray from the
windshield washers of the vehicle ahead. Rotate the end of
the multifunction lever to one of four settings to activate this
feature.
NOTE:
This feature can be programmed through the Uconnect
system. Refer to “Uconnect Settings” in “Multimedia” for
further information.
The sensitivity of the system can be adjusted with the multi -
function lever. Wiper delay position 1 is the least sensitive,
and wiper delay position 4 is the most sensitive.
NOTE:
Position 3 should be used for normal rain conditions. Positions 1 and 2 can be used if the driver desires less wiper
sensitivity. Position 4 can be used if the driver desires more
sensitivity. Place the wiper switch in the O (off) position
when not using the system.
NOTE:
• The Rain Sensing feature will not operate when the wiper
switch is in the low or high-speed position.
• The Rain Sensing feature may not function properly when ice, or dried salt water is present on the windshield.
• Use of Rain-X or products containing wax or silicone may reduce Rain Sensing performance.
The Rain Sensing system has protection features for the
wiper blades and arms, and will not operate under the
following conditions:
• Low Ambient Temperature — When the ignition is first
placed in the ON position, the Rain Sensing system will
not operate until the wiper switch is moved, vehicle speed
is greater than 0 mph (0 km/h), or the outside temperature
is greater than 32°F (0°C).
• Transmission In NEUTRAL (N) Position — When the
ignition is ON, and the transmission is in the NEUTRAL
position, the Rain Sensing system will not operate until the

NOTE:
HomeLink® is disabled when the Vehicle Security Alarm is
active.
NOTE:
Only use this transceiver with a garage door opener that has
a “stop and reverse” feature as required by federal safety
standards. This includes most garage door opener models
manufactured after 1982. Do not use a garage door openerwithout these safety features. Call toll-free 1-800-355-3515 or,
on the Internet at HomeLink.com for safety information or
assistance.
Before You Begin Programming HomeLink®
Be sure that your vehicle is parked outside of the garage
before you begin programming.
For more efficient programming and accurate transmission
of the radio-frequency signal it is recommended that a new
battery be placed in the hand-held transmitter of the device
that is being programmed to the HomeLink® system.
To erase the channels, place the ignition in the ON/RUN
position, and push and hold the two outside HomeLink®
buttons (I and III) for up to 20 seconds or until the orange
indicator flashes.
NOTE:
• Erasing all channels should only be performed when programming HomeLink® for the first time. Do not erase
channels when programming additional buttons.
• If you have any problems, or require assistance, please call toll-free 1-800-355-3515 or, on the Internet at Home-
Link.com for information or assistance.
WARNING!
• Your motorized door or gate will open and close while you are programming the universal transceiver. Do not
program the transceiver if people, pets or other objects
are in the path of the door or gate. Only use this trans -
ceiver with a garage door opener that has a “stop and
reverse” feature as required by Federal safety stan -
dards. This includes most garage door opener models
manufactured after 1982. Do not use a garage door
opener without these safety features.
• Vehicle exhaust contains carbon monoxide, a dangerous gas. Do not run your vehicle in the garage
while programming the transceiver. Exhaust gas can
cause serious injury or death.

5. Press and hold the programmed HomeLink® button andobserve the indicator light.
• If the indicator light stays on constantly, programming is complete and the garage door/device should acti -
vate when the HomeLink® button is pressed.
• To program the two remaining HomeLink® buttons, repeat each step for each remaining button. DO NOT
erase the channels.
Reprogramming A Single HomeLink® Button (Non-Rolling
Code)
To reprogram a channel that has been previously trained,
follow these steps:
1. Place the ignition in the ON/RUN position.
2. Press and hold the desired HomeLink® button until the indicator light begins to flash after 20 seconds. Do not
release the button.
3. Without releasing the button, proceed with “Program -
ming A Non-Rolling Code” step 2 and follow all
remaining steps.Canadian/Gate Operator Programming
For programming transmitters in Canada/United States that
require the transmitter signals to “time-out” after several
seconds of transmission.
Canadian Radio Frequency (RF) laws require transmitter
signals to time-out (or quit) after several seconds of transmis -
sion – which may not be long enough for HomeLink® to pick
up the signal during programming. Similar to this Canadian
law, some US gate operators are designed to time-out in the
same manner.
It may be helpful to unplug the device during the cycling
process to prevent possible overheating of the garage door or
gate motor.
1. Place the ignition inthe ON/RUN position.
2. Place the hand-held transmitter 1 to 3 inches (3 to 8 cm) away from the HomeLink® button you wish to program
while keeping the HomeLink® indicator light in view.
3. Continue to press and hold the HomeLink® button, while you press and release (“cycle”) your hand-held trans-
mitter every two seconds until HomeLink® has success-
fully accepted the frequency signal. The indicator light
will flash slowly and then rapidly when fully trained.
