Universal Remote System
Programming
If equipped, these buttons are in the
overhead console.
This system can replace up to three
remote control transmitters used to
activate devices such as garage
door openers, security systems, and
home automation devices. These instructions refer to a garage door
opener, but can be used for other
devices.
Do not use the Universal Remote
system with any garage door opener
that does not have the stop and
reverse feature. This includes any
garage door opener model
manufactured before April 1, 1982.
Read these instructions completely
before programming the Universal
Remote system. It may help to have
another person assist with the
programming process.
Keep the original hand-held
transmitter for use in other vehicles
as well as for future programming.
Erase the programming when
vehicle ownership is terminated.
See
“Erasing Universal Remote
System Buttons” later in this
section.
To program a garage door opener,
park outside directly in line with and
facing the garage door opener
receiver. Clear all people and
objects near the garage door. Make sure the hand-held transmitter
has a new battery for quick and
accurate transmission of the
radio-frequency signal.
Programming the Universal
Remote System
For questions or help programming
the Universal Remote system, call
1-800-355-3515 or see
www.homelink.com.
Programming involves
time-sensitive actions, and may time
out causing the procedure to be
repeated.
To program up to three devices:
1. Hold the end of the hand-held transmitter about 3 to 8 cm (1
to 3 in) away from the
Universal Remote system
buttons with the indicator light
in view. The hand-held
transmitter was supplied by the
manufacturer of the garage
door opener receiver.
2. At the same time, press and hold both the hand-held
transmitter button and one of
the three Universal Remote

Driving Information
Distracted Driving
Distraction comes in many forms
and can take your focus from the
task of driving. Exercise good
judgment and do not let other
activities divert your attention away
from the road. Many local
governments have enacted laws
regarding driver distraction. Become
familiar with the local laws in
your area.
To avoid distracted driving, always
keep your eyes on the road, hands
on the wheel, and mind on the drive.
. Do not use a phone in
demanding driving situations.
Use a hands-free method to
place or receive necessary
phone calls.
. Watch the road. Do not read,
take notes, or look up
information on phones or other
electronic devices.
. Designate a front seat
passenger to handle potential
distractions. .
Become familiar with vehicle
features before driving, such as
programming favorite radio
stations and adjusting climate
control and seat settings.
Program all trip information into
any navigation device prior to
driving.
. Wait until the vehicle is parked
to retrieve items that have fallen
to the floor.
. Stop or park the vehicle to tend
to children.
. Keep pets in an appropriate
carrier or restraint.
. Avoid stressful conversations
while driving, whether with a
passenger or on a cell phone.
{Warning
Taking your eyes off the road too
long or too often could cause a
crash resulting in injury or death.
Focus your attention on driving.

166 Driving and Operating
Steering
Electric Power Steering
If the vehicle has electric power
steering it does not have power
steering fluid. Regular maintenance
is not required.
If power steering assist is lost due
to a system malfunction, the vehicle
can be steered, but may require
increased effort.
See your dealer if there is a
problem.
If the steering wheel is turned until it
reaches the end of its travel and is
held against that position for an
extended period of time, power
steering assist may be reduced.
If the steering assist is used for an
extended period of time, power
assist may be reduced.
Normal use of the power steering
assist should return when the
system cools down.
See specific vehicle steering
messages underVehicle
Messages 0130.
Variable Effort Steering
Some vehicles have a steering
system that varies the amount of
effort required to steer the vehicle in
relation to the speed of the vehicle.
The amount of steering effort
required is less at slower speeds to
make the vehicle more
maneuverable and easier to park. At
faster speeds, the steering effort
increases to provide a sport-like feel
to the steering. This provides
maximum control and stability.
Hydraulic Power Steering
If the vehicle has hydraulic power
steering, it may require
maintenance. See Power Steering
Fluid (2.4L L4 Engine and 3.6L
V6 Engine with FWD) 0247 or
Power Steering Fluid (3.6L
V6 Engine with AWD) 0247.
If power steering assist is lost
because the engine stops or there is
a system malfunction, the vehicle
can be steered but may require
increased effort. See your dealer if
there is a problem.
Caution
If the steering wheel is turned
until it reaches the end of its
travel, and is held in that position
for more than 15 seconds,
damage may occur to the power
steering system and there may be
loss of power steering assist.
Curve Tips
. Take curves at a reasonable
speed.
. Reduce speed before entering a
curve.
. Maintain a reasonable, steady
speed through the curve.
. Wait until the vehicle is out of
the curve before accelerating
gently into the straightaway.
Steering in Emergencies
.
There are some situations when
steering around a problem may
be more effective than braking.

Caution (Continued)
breaking-in guideline every
time you get new brake
linings.
Following break-in, engine speed
and load can be gradually
increased.
Ignition Positions
(Keyless Access)
The vehicle has an electronic
keyless ignition with pushbutton
start. Pressing the button cycles it through
three modes, ACC/ACCESSORY,
ON/RUN/START, and Stopping the
Engine/OFF.
The transmitter must be in the
vehicle for the system to operate.
If the pushbutton start is not
working, the vehicle may be near a
strong radio antenna signal causing
interference to the keyless access
system. See
Remote Keyless Entry
(RKE) System Operation 028.
To shift out of P (Park), the vehicle
must be in ACC/ACCESSORY or
ON/RUN and the brake pedal must
be applied.
Stopping the Engine/OFF (No
Indicator Lights) : When the
vehicle is stopped, press the
ENGINE START/STOP button once
to turn the engine off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory
Power (RAP) 0183. If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display the
message SHIFT TO PARK in the
Driver Information Center (DIC).
See
Transmission Messages 0138.
When the vehicle is shifted into
P (Park), the ignition system will
switch to OFF.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steady pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting
to N (Neutral), firmly apply the
brakes and steer the vehicle to
a safe location.

3. Come to a complete stop, shiftto P (Park), and turn the
ignition to OFF. On vehicles
with an automatic transmission,
the shift lever must be in
P (Park) to turn the ignition
switch to the OFF position.
4. Set the parking brake. See Parking Brake 0190.
{Warning
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
press and hold the ENGINE START/
STOP button for longer than
two seconds, or press twice in
five seconds.
ACC/ACCESSORY (Amber
Indicator Light) : This mode allows
you to use some electrical
accessories when the engine is off. With the ignition off, pressing the
button one time without the brake
pedal applied will place the ignition
system in ACC/ACCESSORY.
The ignition will switch from ACC/
ACCESSORY to OFF after
five minutes to prevent battery
rundown.
ON/RUN/START (Green Indicator
Light) :
This mode is for driving and
starting. With the ignition off, and
the brake pedal applied, pressing
the button once will place the
ignition system in ON/RUN/START.
Once engine cranking begins,
release the button. Engine cranking
will continue until the engine starts.
See Starting the Engine 0178. The
ignition will then remain in ON/RUN.
Service Only Mode
This power mode is available for
service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may
be required for emission inspection
purposes. With the vehicle off, and
the brake pedal not applied,
pressing and holding the button for
more than five seconds will place the vehicle in Service Only Mode.
The instruments and audio systems
will operate as they do in ON/RUN,
but the vehicle will not be able to be
driven. The engine will not start in
Service Only Mode. Press the
button again to turn the vehicle off.
