Not all manual downshift requests will be allowed
by the transmission. To prevent excessive
engine RPMs, each gear has a maximum vehicle
speed associated with it. Any downshift request
above this speed is not allowed by the
transmission.
If shifting is prevented for any reason, the current
gear ashes multiple times in the Driver
Information Center (DIC), indicating that the
transmission has not shifted gears.
Some automatic downshifts can occur to maintain
minimum engine speed. This only happens if the
vehicle is left in too high of a gear for the vehicle’s
speed. For example, if you have been driving in
sixth gear range and come to a stop without
manually downshifting, the transmission
automatically downshifts to rst gear and displays
rst gear on the HUD. As you begin to drive and
accelerate, the transmission remains in rst gear
until the driver selects a downshift.DSC can be used while using cruise control, but
transmission shifting is different while the
cruise control is on. This is not a malfunction and
is necessary to let proper operation of the
cruise control.
To return to fully automatic operation, move the
shift lever to the right and back into DRIVE (D).
When accelerating your vehicle from a stop
in snowy and icy conditions, you may want to shift
into second gear. A higher gear lets you gain
more traction on slippery surfaces.
In higher gears, on the XLR only, an automatic
downshift occurs if you press the accelerator pedal
to the oor. This feature provides adequate
acceleration capabilities if you forget to downshift
manually. Tap the shifter forward and the
vehicle upshifts.

5. Push and hold the
bottom of the
retractable hardtop
button located
on the console
behind the shifter
lever.
The windows will automatically lower and the top
will automatically lower into the storage area.
A chime will sound when the top has lowered
completely.
If the radio is on, the sound may be muted brie y
while the retractable top is lowered. This occurs
because a new audio system equalization is being
loaded.
Under certain conditions, the Driver Information
Center (DIC) may display messages regarding the
retractable hardtop. If the CLOSE CARGO
DIVIDER, TOO COLD TO MOVE TOP, TOP
INOP - VALET ON, TOP INOP OUT OF PARK,TOP MOTOR OVER TEMP or TOP NOT SECURE
messages display, seeDIC Warnings and
Messages on page 206for 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 82.
Raising the Retractable Hardtop
1. Park on a level surface. 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.
4. Make sure nothing or no one is on or
around the top. Make sure the trunk
cargo cover is in place with no cargo on top
of or in front of the cargo cover. SeeRear
Storage Area on page 123for more
information. Also, be sure the valet lockout
switch is off.

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 messages regarding the
retractable hardtop. If the CLOSE CARGO
DIVIDER, TOO COLD TO MOVE TOP, TOP
INOP - VALET ON, TOP INOP OUT OF PARK,
TOP MOTOR OVER TEMP or TOP NOT SECURE
messages display, seeDIC Warnings and
Messages on page 206for 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 82.
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 65andTrunk on page 77for more
information.
3. Raise the trunk by hand.

When Rainsense™ is active, the headlamps will
turn on automatically. If it is dark, they will
remain on. See “Wiper-Activated Headlamps”
underExterior Lamps on page 164for more
information.
Notice:Do not place stickers or other items
on the exterior glass surface directly in front of
the moisture sensor. Doing this could cause

continue to clear the window for about six seconds
after the button is released and then stop or
return to your preset speed.
{CAUTION:
In freezing weather, do not use your
washer until the windshield is warmed.
Otherwise the washer uid can form ice
on the windshield, blocking your vision.
If the uid in the windshield washer uid reservoir
is low, the message LOW WASHER FLUID will
appear on the Driver Information Center (DIC)
display. It will take 60 seconds after the bottle is
re lled for this message to turn off. For information
on the correct washer uid mixture to use, see
Windshield Washer Fluid on page 397and
Recommended Fluids and Lubricants on page 473.
Headlamp Washer
The headlamps washer only functions every fourth
time the washer button is depressed and if the
headlamps are on.

startled by Adaptive Cruise Control
response and even lose control. Keep
your HUD on and properly adjusted when
using Adaptive Cruise Control.
The set speed is selected by the driver. This is the
speed you will travel if there is not a vehicle
detected in your path.
To set Adaptive Cruise Control, do the following:
1. Make sure the Head-Up Display (HUD) is
on and properly adjusted. SeeHead-Up
Display (HUD) on page 171for more
information.
2. Move the switch to on.
