2005 Cadillac DeVille Owner ManualM

Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly.
But the notice will tell what to do to help avoid
the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.

{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.
Your vehicle has a light
that comes on as a
reminder to buckle up.
SeeSafety Belt Reminder
Light on page 3-45.In most states and in all Canadian provinces, the law
says to wear safety belts. Here is why:They work.
You never know if you will be in a crash. If you do have
a crash, you do not 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 would not
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!

Driver Position
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see “Seats” in the Index.
3. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.The lap-shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.
4. Push the latch plate into the buckle until it clicks.
Be sure to use the correct buckle when buckling
your lap-shoulder belt. If you nd that the latch plate
will not go fully into the buckle, see if you are
using the buckle for the center passenger position.
Pull up on the latch plate to make sure it is
secure. If the belt is not long enough, seeSafety
Belt Extender on page 1-27.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
1-13

Lap-Shoulder Belt
All rear seating positions have lap-shoulder belts.
Here is how to wear one properly.
1. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
The shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.2. Push the latch plate into the buckle until it clicks.
The latch plates for the safety belts in each rear
seating position vary in size. If the center rear or the
left rear latch plate is inserted into the incorrect
buckle, the plate will not latch properly. Be sure you
are using the correct buckle and that the latch
plate clicks when inserted into the buckle.
If the belt stops before it reaches the buckle, tilt the
latch plate and keep pulling until you can buckle it.
