2007 CADILLAC DTS Underseat

Center Flex Storage Unit
Your vehicle may have a center ex storage unit
that includes a front center seat with a lap belt and
an underseat storage compartment. The center
seatback can also be used as a fold down armrest.
Cupholders are also located at the front edge of
the storage unit and can be accessed by
folding the compartment forward.
When not being used, the center seat lap belt can
be stored in the underseat storage compartment.
Floor Mats
The oor mats are designed to remain in position
under your feet and out of reach of the
accelerator pedal. The driver side oor mat is held
in place by two locator pins and the passenger
side is held in place by one.
Make sure that the driver side oor mat is properly
placed on the oor so that it does not block the
movement of the accelerator pedal.To remove a oor mat,
pull up on the rear of
the mat to disconnect it
from the locator pins.
To reinstall the oor mats, line up the openings in
the oor mat over the locator pins and push it
down into place.

Turn and Lane-Change Signals
To signal a turn, move the lever all the way up
or down. The lever returns automatically when the
turn is complete. If you momentarily press and
release the lever, the turn signal will ash 3 times.
An arrow on the
instrument panel
cluster and in the
outside rearview
mirror will ash in the
direction of the turn
or lane change.
Raise or lower the lever until the arrow starts to
ash to signal a lane change. Hold it there until
the lane change is complete. The lever returns
when it is released.
If the turn signal is left on, a warning chime will
sound and the Driver Information Center (DIC) will
display TURN SIGNAL ON after driving about a
mile to remind you to turn it off. SeeDIC Warnings
and Messages on page 246.Arrows that ash rapidly when signaling for a
turn or lane change may be caused by a burned
out signal bulb. Other drivers will not see the
turn signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse and for burned-out bulbs
if the arrow fails to work when signaling a turn.
SeeRear Underseat Fuse Block on page 455.
Headlamp High/Low-Beam Changer
Push forward to change the headlamps from
low beam to high. Pull the lever back and then
release it to change from high beam to low.
This light on the
instrument panel cluster
will be on, indicating
high-beam usage.

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.
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.
The battery is located under the rear seat cushion.
To access the battery, seeRear Underseat
Fuse Block on page 455. You do not need to
access the battery to jump start your vehicle. See
Jump Starting on page 392.
{CAUTION:
A battery that is not properly vented can
let sulfuric acid fumes into the area under
the rear seat cushion. These fumes can
damage your rear seat safety belt
systems. You may not be able to see this
damage, and the safety belts might not
provide the protection needed in a crash.
If a replacement battery is ever needed, it
must be vented in the same manner as
the original battery. Always make sure
that the vent hose is properly reattached
before reinstalling the seat cushion.

Notice:If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The repairs
would not be covered by your warranty.
Always turn off your radio and other
accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles.
Unplug unnecessary accessories plugged into
the cigarette lighter or the accessory power
outlets. Turn off the radio and all lamps
that are not needed. This will avoid sparks
and help save both batteries. And it could
save the radio!
4. Open the hoods and locate the positive (+)
and negative (−) terminal locations on the
other vehicle. Your vehicle has a remote
positive (+) jump starting terminal and
a remote negative (−) jump starting terminal.The remote positive (+) terminal is located in
the engine compartment on the passenger’s
side of the vehicle. Lift the red plastic cap
to access the terminal. SeeEngine
Compartment Overview on page 364for more
information on the location of the remote
positive (+) terminal.
A second remote positive (+) terminal is
located on the rear underseat fuse block.
