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.

Power Windows
The power window
switches are located on
each door near the
armrest.
Press the up or down arrows on the switches to raise or
lower the windows.
Your vehicle has Retained Accessory Power (RAP)
that allows you to use the power windows once
the ignition has been turned off. For more information,
seeRetained Accessory Power (RAP) on page 2-22.
Power Window Initialize
After a power reconnect such as battery replacement,
the express-up and index-up features will not function
until the system is initialized. Once power is restored,
do the following:
1. Close the door.
2. Raise the window by holding the up arrow on the
power window switch.
3. Hold the up arrow for three seconds after the
window is closed. Release the switch. Then hold
the up arrow again for three seconds.
The express-up system must be initialized to operate the
windows with the door open and the retractable hardtop.
Express-Down Window
This feature is on both power windows. Press the down
arrow on the switch to the second position to activate
the express-down feature. If you want to stop the
window as it is lowering, press the switch again.
Express-Up Window
This feature is on both power windows. Press the
up arrow on the switch to the second position to
activate the express-up feature. If you want to stop
the window as it is raising, press the switch again.

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 “Battery
Replacement” underKeyless Access System
Operation on page 2-5for more information.
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 ACC
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?.

Battery
Your vehicle has a maintenance free battery. When it is
time for a new battery, get one that has the replacement
number shown on the original battery’s label. We
recommend an ACDelco
®replacement battery.
For battery replacement, see your dealer or the service
manual. To purchase a service manual, seeService
and Owner PublicationsinService Publications Ordering
Information on page 8-12.
Warning:Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands
after handling.
Vehicle Storage
If you are not going to drive your vehicle for 25 days or
more, remove the black, negative (−) cable from the
battery. This will help keep your battery from
running down.
{CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
are not careful. SeeJump Starting on
page 6-37for tips on working around a battery
without getting hurt.
You must close all doors and the trunk before
reconnecting the battery. After reconnecting the battery,
you must press the unlock button on the keyless
access transmitter. Failure to follow this procedure may
result in the alarm sounding. Pressing unlock on the
keyless access transmitter would stop the alarm.
Also, for your audio system, seeTheft-Deterrent Feature
on page 3-78.
