Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
You can tell the battery is weak if the transmitter will not
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it is probably time to change the battery.
The KEY FOB BATT LOW message in the vehicle’s
DIC will display if the remote keyless entry transmitter
battery is low.
Notice:When replacing the battery, use care not
to touch any of the circuitry. Static from your
body transferred to these surfaces may damage
the transmitter.To replace the battery in the remote keyless entry
transmitter, do the following:
1. Insert a at object, with a thin edge, into the notch
located below the panic alarm button, and separate
the bottom half from the top half of the transmitter.
2. Remove the old battery. Do not use a metal object
to do this.
3. Slide the new battery into the transmitter with the
positive (+) side of the battery facing up. Use
one three-volt, CR2032 battery, or equivalent type.
4. Snap the front and the back of the transmitter
together. Make sure the cover is on tight, so water
will not get inside the transmitter.
5. Test the operation of the transmitter with the vehicle.

The remote vehicle start feature will not operate if any
of the follow occur:
The remote start system is disabled through
the DIC.
The vehicle’s key is in the ignition.
A door on the vehicle is open.
The vehicle’s hood is open.
The hazard warning ashers are on.
The check engine light is on. SeeMalfunction
Indicator Lamp on page 3-41.
The engine coolant temperature is too high.
The oil pressure is low.
Two remote vehicle starts have already been
provided for that ignition cycle.
If a remote start is attempted and is unsuccessful, the
Driver Information Center (DIC) will display REMOTE
START DISABLED.Vehicles that have the remote vehicle start feature are
shipped from the factory with the remote vehicle start
system enabled. The system may be enabled or disabled
through the DIC. See “REMOTE START” underDIC
Vehicle Personalization on page 3-75for additional
information. If your vehicle does not have the DIC feature,
and remote vehicle start was installed at the dealership,
you will need to have the dealership enable or disable
the system.
Remote Start Ready
If your vehicle does not have the remote vehicle start
feature, it may have the remote start ready feature. This
feature allows your dealer to add the manufacturer’s
remote vehicle start feature.
If the keyless entry transmitter has a plus (+) symbol
on the back cover, your vehicle has the remote
start ready feature. You can lock or unlock your
vehicle from approximately 492 feet (150 m) away.
See your dealer if you would like to add the
manufacturer’s remote vehicle start feature to
your vehicle.

feature can be turned off. See “Content Theft” under
DIC Vehicle Personalization on page 3-75.
Delayed Locking
Your vehicle may have this feature. If so, it delays the
locking of the vehicle’s doors for ve seconds after the
last door is closed. Two chimes will sound when the
power door lock switch or the LOCK button on the remote
keyless entry transmitter is pressed when a door is open.

on. If your vehicle has a Driver Information Center (DIC),
a warning will be displayed.
The doors can be locked immediately by pressing the
power door lock switch or the LOCK button on the
transmitter a second time.
The delayed locking feature will not activate when the
ignition is in RUN or ACCESSORY.
You can program this feature on or off through the
Driver Information Center (DIC), if equipped. See
“Delayed Locking” underDIC Vehicle Personalization
on page 3-75.

Ignition Positions
With the ignition key in the ignition, the key can be
turned to four different positions:
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is in all the way. If
none of this works, then your vehicle needs service.
A (OFF):This is the only position in which the ignition
key can be inserted or removed. This position locks
the ignition and transaxle. It is a theft-deterrent feature.B (ACCESSORY):This position lets the radio and
windshield wipers operate while the engine is off.
To use ACCESSORY, turn the key clockwise.

Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.
1. Press the cruise on/off button. The indicator light in
the button will come on.
2. Get up to the speed you want.
3. Press the SET−button. The cruise symbol will
display in the instrument panel cluster when the
system is engaged.
4. Take your foot off the accelerator pedal.
Resuming a Set Speed
Suppose you set your cruise control at a desired
speed and then you apply the brake. This, of course,
disengages the cruise control. The cruise symbol in the
instrument panel cluster will go out, indicating cruise
control is no longer engaged.To return to your previously set speed, press the
RES + button once you are going about 25 mph
(40 km/h) or more.
You will go right back up to your chosen speed and
stay there.
If you hold the RES + button, the vehicle will keep going
faster until you release the button or apply the brake.
So unless you want to go faster, do not hold the RES +
button.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher
speed. Press the SET−button, then release
the button and the accelerator pedal. You’ll now
cruise at the higher speed.
Press the RES + button. Hold it there until you get up
to the speed you want, and then release the button.
To increase your speed in very small amounts, press
the button briey. Each time you do this, your vehicle
will go about 1 mph (1.6 km/h) faster.
3-11

The URPA display is located inside the vehicle, above the
rear window. It has three color-coded lights that can be
seen through the rearview mirror or by turning around.
{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully before
backing up. The system does not operate above
typical backing speeds of 3 mph (5 km/h) while
parking. And, the system does not detect
objects that are more than 5 feet (1.5 meters)
behind the vehicle.
So, unless you check carefully behind you
before and when you back up, you could strike
children, pedestrians, bicyclists or pets behind
you, and they could be injured or killed.
Whether or not you are using rear park assist,
always check carefully behind your vehicle
before you back up and then watch closely as
you do.
How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R). When the system comes on,
the three lights on the display will briey illuminate to let
you know that the system is working. If your vehicle is
moving in REVERSE (R) at a speed greater than 3 mph
(5 km/h), the red light will ash to remind you the system
does not work at this speed.
The rst time an object is detected while in
REVERSE (R), a chime will sound and the following
will occur in sequence, depending on the distance from
the object:
At 5 feet (1.5 m) a chime will sound and one amber
light will be lit.
At 40 inches (1.0 m) both amber lights will be lit.
At 20 inches (0.5 m) a continuous chime will sound
and all three lights (amber/amber/red) will be lit.
At 1 foot (0.3 m) a continuous chime will sound and
all three lights (amber/amber/red) will ash.
URPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (25.4 cm) tall, but it cannot detect
objects that are above trunk level. In order for the
rear sensors to recognize an object, it must be within
operating range.
