2003 CADILLAC DEVILLE Owners Manual

Massaging Lumbar
If your vehicle has this
feature, the control is
located on the outboard
sides of the front seats.
With the ignition on, brie¯y
press the top of the control
where it is marked AUTO to
activate the massaging
lumbar feature.
The massage cycle will run continuously for up to
10 minutes and can be interrupted by brie¯y pressing the
bottom of the control. The lumbar support can be
adjusted during the massage cycle by moving the control
forward to increase support and rearward to decrease
support. The massage cycle will continue to run even if
the ignition is turned to OFF unless interrupted.
If your vehicle has this feature, it will not have the
adaptive seat feature.
Adaptive Seat Control
If your vehicle has this
feature, the control is
located on the outboard
side of each front seat.
It is marked AUTO.
With the ignition in ON, ®rst use the power seat control
to get the proper position. Then press the top of the
control where it is marked AUTO. The system will in¯ate
the cushion and take a reading, then automatically
de¯ate the cushion to a suggested level of comfort by
distributing the pressure evenly. The seatback and
cushion will in¯ate to adjust to the driver's body position
in two to four-minute cycles.
1-3

You may still wish to further adjust the overall ®rmness
or softness of the seat cushion. To get to your
desired level of comfort, hold the control up to increase
the ®rmness, or down for less ®rmness. When you
let go of the control, the seat will automatically readjust
to your desired level of comfort.
To reshape the lower seatback, press the lumbar
control forward to increase support and rearward to
decrease support. The lumbar will then automatically
adjust to your body's positioning for the duration of the
trip in two to four-minute cycles.
If you exit the vehicle after the system has been
activated and the seat is left unoccupied for more than
two minutes, the system will de¯ate. You will then
need to readjust the lumbar support upon returning to
your vehicle.
To turn off the adaptive seat feature, brie¯y press the
bottom of the control. The seat will de¯ate when
the adaptive seat control or the ignition is turned off.
If your vehicle has this feature, massaging lumbar is not
available for your vehicle.Heated Seats
Your vehicle may have heated front and rear seats.
The buttons are located on the armrests. Press the
buttons to turn the feature on. Press them again to turn
off the heated seats. The feature will also shut off
when the ignition is turned to OFF.
The HEAT/OFF button controls the temperature settings
HI, MED and LO. The other button is to choose BACK
ONLY heating. The LO setting warms the seatback and
cushion until the seat approximates body temperature.
The MED and HI settings heat the seatback and
seat cushion to a slightly higher temperature, and the
BACK ONLY heats only the seatback.
1-4

The temperature can be adjusted by pushing the button
from HI to LO or, until the desired setting is reached.
You will be able to feel heat in approximately two
minutes. To heat just the seatback, push the BACK
ONLY button once, after ®rst activating the heated seat
feature. To resume heat to both the seat cushion
and seatback, press the button again.Reclining Seatbacks
The recliner controls are
located on the outboard
sides of the front seats.
Press the recliner control forward or rearward to adjust
the seatback forward or rearward.
1-5

But don't have a seatback reclined if your vehicle
is moving.
{CAUTION:
Sitting in a reclined position when your vehicle
is in motion can be dangerous. Even if you
buckle up, your safety belts can't do their job
when you're reclined like this.
The shoulder belt can't do its job. In a crash,
you could go into it, receiving neck or other
injuries.
The lap belt can't do its job either. In a crash the
belt could go up over your abdomen. The belt
forces would be there, not at your pelvic bones.
This could cause serious internal injuries.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit well
back in the seat and wear your safety belt
properly.

Head Restraints
Adjust your head restraint so that the top of the restraint
is closest to the top of your head. This position
reduces the chance of a neck injury in a crash.The front head restraints are adjustable. Lift up or push
down on the head restraint to raise or lower it. Pull
forward or push rearward on the head restraint to tilt it
forward or rearward.
The rear head restraints work the same way as the front
head restraints, except that they do not tilt forward or
rearward.
1-7

Rear Seats
Power Lumbar
Your vehicle may be equipped with four-way lumbar
support, without the massage feature, for the outboard
rear seating positions.
The rear lumbar support
controls are located on the
rear door trim panels.To activate the rear lumbar support feature, push forward
on the control to increase support or rearward to
decrease support. The lumbar control can also be moved
up and down to adjust the location of the support.

Safety Belts
Safety Belts: They Are for Everyone
This part of the manual tells you how to use safety
belts properly. It also tells you some things you should
not do with safety belts.
{CAUTION:
Don't let anyone ride where he or she can't
wear a safety belt properly. If you are in a
crash and you're not wearing a safety belt,
your injuries can be much worse. You can hit
things inside the vehicle or be ejected from it.
You can be seriously injured or killed. In the
same crash, you might not be, if you are
buckled up. Always fasten your safety belt,
and check that your passengers' belts are
fastened properly too.
{CAUTION:
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are more
likely to be seriously injured or killed. Do not
allow people to ride in any area of your vehicle
that is not equipped with seats and safety
belts. Be sure everyone in your vehicle is in a
seat and using a safety belt properly.
1-9

Your vehicle has a light
that comes on as a
reminder to buckle up. See
Safety Belt Reminder
Light on page 3-45.
In most states and in all Canadian provinces, the law
says to wear safety belts. Here's why:
They work.
You never know if you'll be in a crash. If you do have a
crash, you don't know if it will be a bad one.
A few crashes are mild, and some crashes can be so
serious that even buckled up, a person wouldn't survive.
But most crashes are in between. In many of them,
people who buckle up can survive and sometimes walk
away. Without belts they could have been badly hurt or
killed.
After more than 30 years of safety belts in vehicles, the
facts are clear. In most crashes buckling up does
matter... a lot!
Why Safety Belts Work
When you ride in or on anything, you go as fast as
it goes.
Take the simplest vehicle. Suppose it's just a seat on
wheels.
