Retractable Hardtop
The following procedures explain the proper operation
of the retractable hardtop. The retractable hardtop
will not operate if the valet lockout switch is on.
If the retractable hardtop is lowered or raised multiple
times, the engine should be running while doing so
to prevent drain on the vehicle’s battery.
{CAUTION:
When the retractable hardtop is opened or
closed, people can be injured by the parts that
move: the hardtop and its mechanism, the
trunk lid, and the side windows. Keep people
away from these parts when you are lowering
or raising the top.
Lowering the Retractable Hardtop
Notice:Leaving the retractable hardtop down and
exposing the interior of your vehicle to outdoor
conditions may cause damage. Always close
the retractable hardtop if leaving your vehicle
outdoors.
1. Park on a level surface and shift the transmission
into PARK (P).
2. The vehicle’s engine must be on or in Acc.
3. Lower both sun visors.
Notice:Raising or lowering the top while the
vehicle is in motion can cause damage to the top
or top mechanism. Make sure the vehicle is in
PARK (P) to lower or raise the top.
Notice:Lowering the top if it is damp, wet, or dirty
can cause stains, mildew, and damage to the
inside of your vehicle. Dry off the top before
lowering it.
4. Make sure that nothing or no one is on or around
the top. Make sure the trunk cargo cover is in
place with nothing on top or in front of the cargo
cover. SeeRear Storage Area on page 2-53
for more information. Also, make sure the valet
lockout switch is off.
2-54

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 messages regarding the
retractable hardtop. SeeDIC Warnings and Messages
on page 3-63for more information.
If the retractable hardtop does not operate, and there
are no messages displayed on the Driver Information
Center (DIC), then perform the “Power Window Initialize”
steps underPower Windows on page 2-17.Manually Raising the Retractable Hardtop
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. SeeKeys on
page 2-3andTrunk on page 2-13for more
information.
3. Raise the trunk by hand.
4. 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 retractable hardtop button
when the hydraulic pump valve is open could
damage the pump. Always close the hydraulic pump
valve after the retractable hardtop has been closed
manually.

Battery Run-Down Protection
Your vehicle has a feature to help prevent the battery
from being drained, in case the underhood lamp, vanity
mirror lamps, cargo lamps, reading lamps, console, or
glove box lamps are accidentally left on, or something is
left plugged into the accessory power outlet or cigarette
lighter. If any of the accessory lamps are left on, they will
automatically time-out after about 10 minutes. To reset
the battery protection, all of the above lamps must be
turned off or the ignition must be in the Acc. position.
Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high in
your eld of view, it may take you more time to
see things you need to see when it is dark
outside. Be sure to keep the HUD image dim
and placed low in your eld of view.
The Head-Up Display (HUD) allows you to see some of
the driver information that appears on your instrument
panel cluster.The information may be displayed in English or metric
units and appears as an image focused out toward
the front of your vehicle. To change from English
to metric units, seeDriver Information Center (DIC)
on page 3-60.
The HUD consists of the following information:

The following Adaptive Cruise Control (ACC) messages
may appear in the HUD:
CRUISE SPEED LIMITED:This message indicates that
your vehicle speed has been reduced below your set
speed due to ACC limitations. Your set speed is too high
and ACC cannot detect other vehicles at far enough
distances for the system to operate properly.
TIGHT CURVE:This message indicates that ACC has
reduced your vehicle speed due to a tight curve in
the road. Once the road straightens, ACC will return to
your selected set speed or follow distance setting.
See “Adaptive Cruise Control (ACC)” underTurn
Signal/Multifunction Lever on page 3-8for more
information.
You may also see an ACC active symbol, alert symbol
or vehicle ahead symbol. See “Adaptive Cruise
Control (ACC)” underTurn Signal/Multifunction Lever
on page 3-8for more information.Accessory Power Outlet(s)
The accessory power outlet can be used to connect
electrical equipment such as a cellular phone or
CB radio.
The accessory power outlet is located inside the
center console storage compartment, on the forward
left side.
To use the outlet, remove the tethered cap. When not
using it, always cover the outlet with the protective cap.
Notice:When using an accessory power outlet,
maximum electrical load must not exceed 20 amps.
Always turn off any electrical equipment when
not in use. Leaving electrical equipment on for
extended periods will drain your vehicle’s battery.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses. If you experience a
problem, see your dealer for additional information
on accessory power outlets.
3-36

The rear window defogger and heated mirrors are
automatically disabled when the retractable hardtop
is moving or down.
Notice:Do not use anything sharp on the inside
of the rear window. If you do, you could cut or
damage the warming grid, and the repairs would
not be covered by your warranty. Do not attach
a temporary vehicle license, tape, a decal or
anything similar to the defogger grid.
Outlet Adjustment
Use the thumbwheel to open or close the outlets.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the area around the base of the instrument
panel console and air path under the seats
clear of objects to help circulate the air inside
of your vehicle more effectively.
Passenger Compartment Air Filter
The passenger compartment air lter removes certain
particles from the air, including pollen and dust particles.
Reductions in airow, which may occur more often in
dusty areas, indicate that the lter may need to be
replaced early.
The lter should be replaced as part of the routine
scheduled maintenance. SeeScheduled Maintenance
on page 7-4for more information.
To check or replace the air lter, do the following:
1. With the hood open, unlatch and remove the
access panel.
The passenger compartment air lter and access
panel are located on the passenger’s side of
the engine compartment near the battery.
SeeEngine Compartment Overview on page 6-12
for more information on location.
2. Pull the old lter out of the housing.
3. Insert the new lter into the housing.
4. Reinstall the air lter access panel.
3-42

Voltmeter Gage
When the vehicle is in
accessory mode, the
voltmeter shows the
voltage output of your
battery. When the engine
is running, it shows
the voltage output of
the charging system.
The reading will change as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, your instrument panel
cluster and other systems may shut down. The Driver
Information Center (DIC) will read LOW VOLTAGE when
your vehicle is at 10 volts or below. Have it checked
right away. Driving with the voltmeter reading at
10 volts or below could drain your battery and disable
your vehicle.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
This light should come on when you start the engine.
If it does not come on then, have it xed so it will
be ready to warn you if there is a problem.
If this warning light stays on after you start the engine,
the parking brake may still be set or there could be
a brake problem. Refer toParking Brake on page 2-30
to see if it is set. If the parking brake is not set, have
your brake system inspected right away.

Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have
or might begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the check
engine light is on or not working properly.
To perform a check engine light bulb check with the
keyless ignition, make sure the transmitter fob is
in the passenger compartment. SeeIgnition Positions
on page 2-23. Press the bottom of the Acc. button
on the instrument panel and hold the button down for
ve seconds. The instrument panel, including the check
engine light, will light up and the ignition will be on,but the engine will not start — if you press the bottom
of the Acc. button only briey, less than ve seconds,
the accessory power mode will be turned on, but not
the ignition. After the bulb check, be sure to press and
release the Acc. button again to turn the ignition off
and avoid draining the vehicle’s battery.
Your vehicle will not pass this inspection if the
OBD (on-board diagnostic) system determines that
critical emission control systems have not been
completely diagnosed by the system. The vehicle would
be considered not ready for inspection. This can
happen if you have recently replaced the battery or
if the battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your
vehicle still does not pass the inspection for lack of
OBD system readiness, your dealer/retailer can prepare
the vehicle for inspection.
