Changes or modi®cations to this system by other than
an authorized service facility could void authorization to
use this equipment.
If you ever notice a decrease in the remote keyless
entry transmitter range, try doing one of the following:
·Check the distance. You may be too far from
your vehicle. You may need to stand closer during
rainy or snowy weather.
·Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.

Battery Replacement
Under normal use, the battery in your keyless access
transmitter should last about three 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.
A weak battery may also cause the DIC to display NO
FOBS DETECTED when you try to start the vehicle. If
this happens, place the transmitter in the glove box
transmitter pocket with the buttons facing to the right.
Then, with the vehicle in PARK (P) or NEUTRAL (N),
press the brake pedal and the START button. Although
this will start the vehicle, it is recommended that you
replace the transmitter battery as soon as possible. The
DIC may display FOB BATTERY 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.1. Insert a coin or similar object into the slot on the
back of the transmitter and gently pry apart the
front and back.
2. Gently pull the battery out of the transmitter.
3. Put the new battery in the transmitter, positive (+)
side up. Use a battery, type CR2032, or equivalent.
4. Reassemble the transmitter. Make sure to put
it together so water will not get in.
5. Test the transmitter.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you
can help.
Theft-Deterrent System
Your vehicle is equipped with a theft-deterrent alarm
system.
With this system, the
security light will ¯ash
when the door is open and
locked with the power
door lock switch.
If this light is on continuously while the engine is
running, your vehicle needs service.
Arming the System
Use one of the two following items listed here to arm
the system:
·Press the lock button on the keyless access
transmitter.
·Open the door. Lock the door with the power door
lock switch. The SECURITY light should ¯ash.
Close the door. The SECURITY light will stop
¯ashing and stay on. After 30 seconds, the light
should turn off.
·The vehicle can be programmed to automatically
lock the doors when you exit the vehicle. See
DIC Vehicle Personalization on page 3-66.
Now, if a door or the trunk lid is opened without the
keyless access transmitter, the alarm will go off. Your
horn will sound for two minutes, then it will go off to save
battery power. And, your vehicle will not start without
a keyless transmitter present.
The theft-deterrent system will not arm if you lock the
driver's door with the power door lock switch after
the doors are closed.
If your passenger stays in the vehicle when you leave
with the keyless access transmitter, have the passenger
lock the vehicle after the doors are closed. This way the
alarm will not arm, and your passenger will not set it off.
2-17

When the engine is off, press this button to place the
vehicle in ACCESSORY mode. ACCESSORY
MODE ACTIVE will display on the Driver Information
Center (DIC). This mode allows you to use things
like the radio and the windshield wipers while the engine
is off. Use ACCESSORY if you must have your vehicle
in motion while the engine is off, for example, if your
vehicle is being pushed or towed. If the door is
open while in ACCESSORY, the key in reminder chime
will sound continuously.
Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 10 minutes after the engine is turned off:
·Radio
·Power Windows
·Audio Steering Wheel Controls
Power to these accessories stops after 10 minutes or if
a door is opened. If you want power for another
10 minutes, close all the doors and press the
OFF/ACCESSORY button to place the vehicle in
ACCESSORY mode. Press the button again and the
vehicle will return to RAP.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position ± that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
The keyless access transmitter must be in the vehicle
for the ignition to work.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
1. With your foot on the brake pedal, press the
START button. When the engine begins cranking,
let go of the button. The idle speed will go down as
your engine gets warm.
If the battery in the keyless access transmitter is
weak, the DIC will display FOB BATTERY
LOW. You can still drive the vehicle. See ªBattery
Replacementº under
Keyless Access System
Operation on page 2-4for more information.
2-20

Notice:Holding the button in for longer than
15 seconds at a time will cause the battery to be
drained much sooner. This can also cause damage
to the starter motor. Wait 15 seconds between
each try to avoid draining your vehicle's battery or
damaging the starter.
2. If the engine does not start and no DIC message is
displayed, wait 15 seconds before trying again.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly.
Stopping Your Engine
Move the shift lever to PARK (P) and press the
OFF/ACCESSORY button. If the shifter is not in PARK
(P), the vehicle will go into ACCESSORY mode and
the DIC will display SHIFT TO PARK. Once the shifter
is moved to PARK (P), the vehicle will turn off.If the keyless access transmitter is not detected
while going to off, the DIC will display NO FOB, OFF
OR RUN.
See
DIC Warnings and Messages on page 3-57for
more information.
Engine Coolant Heater
Your vehicle may be equipped with an engine coolant
heater.
In very cold weather, 0ÉF (-18ÉC) or colder, the engine
coolant heater can help. You will get easier starting
and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle. At
temperatures above 32ÉF (0ÉC), use of the coolant
heater is not required.

5. Push and hold the top
of the retractable
hardtop button located
behind the shift
lever. The windows will
automatically lower
and the top will raise. A
chime will sound
when the top has
raised completely.
After the top is fully raised, release the retractable
hardtop button. If you press the button again within ®ve
seconds, the windows will automatically close.
If your radio is on, you may notice a brief mute in
sound. This is normal and due to a new audio system
equalization being loaded for the vehicle with the
top raised.
Under certain conditions, the Driver Information Center
(DIC) may display a message regarding the retractable
hardtop. If this happens, see
DIC Warnings and
Messages on page 3-57for more information.If your vehicle has a power loss, such as a dead
battery, you can still raise the top manually by doing the
following:
1. Lower both sun visors and open both doors.
2. Use the key to open the trunk. See
Keys on
page 2-2andTrunk on page 2-11for more
information.
3. Raise the trunk by hand.
4. Remove the wrench located inside the passenger's
side storage compartment.
5. Find the hydraulic
pump under the carpet
on the rear driver's side
of the trunk. Open the
valve by turning it
counterclockwise with
your hand until it stops.
Notice:Pressing the convertible top button when
the hydraulic pump valve is open could damage the
pump. Always close the hydraulic pump valve
after the top has been closed manually.
