2005 CADILLAC DEVILLE Owners Manual

{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.
To be sure the vent hose (A) is properly attached, the
vent hose connectors (B) must be securely reattached to
the vent outlets (C) on each side of the battery, and
the vent assembly grommet (D) must be secured to the
oor pan (E).

Vehicle Storage
If you are not going to drive your vehicle for 25 days or
more, remove the black, negative (−) cable from the
battery. This will help keep your battery from
running down.
{CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
are not careful. SeeJump Starting on
page 5-42for tips on working around a battery
without getting hurt.
Jump Starting
If you cannot start your vehicle and you are unable to
remove your key from the ignition, see “Shift Lock
Release” underAutomatic Transaxle Operation on
page 2-28.
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. Be sure to use the following steps to do it safely.
{CAUTION:
Batteries can hurt you. They can be dangerous
because:
They contain acid that can burn you.
They contain gas that can explode or
ignite.
They contain enough electricity to
burn you.
If you do not follow these steps exactly, some
or all of these things can hurt you.

Notice:Ignoring these steps could result in costly
damage to your vehicle that would not be covered
by your warranty.
Trying to start your vehicle by pushing or pulling it
will not work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice:If the other vehicle’s system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles are not touching
each other. If they are, it could cause a ground
connection you do not want. You would not be able
to start your vehicle and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake rmly on both vehicles involved in
the jump start procedure. Put an automatic
transaxle in PARK (P) or a manual transaxle in
NEUTRAL before setting the parking brake.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!
5-43

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. A second
remote positive (+) terminal
is located on the rear
underseat fuse block. Lift
the red plastic cap to
access the terminal.
The remote negative (−) terminal is located near
the power steering uid reservoir. It is marked
GND (−). SeeEngine Compartment Overview on
page 5-12for more information on location.You will not see the battery of your vehicle under
the hood. It is located under the rear passenger’s
seat. You will not need to access the battery
for jump starting. The remote positive (+) terminal is
for that purpose.
{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you. Keep
hands, clothing and tools away from any
underhood electric fan.
5-44

{CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing
this, and some have been blinded. Use a
ashlight if you need more light.
Be sure the battery has enough water. You do
not need to add water to the battery installed
in your new vehicle. But if a battery has ller
caps, be sure the right amount of uid is there.
If it is low, add water to take care of that rst.
If you do not, explosive gas could be present.
Battery uid contains acid that can burn you.
Do not get it on you. If you accidentally get it
in your eyes or on your skin, ush the place
with water and get medical help immediately.
{CAUTION:
Fans or other moving engine parts can injure
you badly. Keep your hands away from moving
parts once the engine is running.
5. Check that the jumper cables do not have loose or
missing insulation. If they do, you could get a
shock. The vehicles could be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+) will go to
positive (+) or to a remote positive (+) terminal if
the vehicle has one. Negative (−) will go to a heavy,
unpainted metal engine part or to a remote
negative (−) terminal if the vehicle has one.
Do not connect positive (+) to negative (−)oryou
will get a short that would damage the battery
and maybe other parts too. And do not connect the
negative (−) cable to the negative (−) terminal on
the dead battery because this can cause sparks.
5-45

6. Connect the red
positive (+) cable to the
remote positive (+)
terminal location on the
vehicle with the dead
battery. Use a remote
positive (+) terminal if
the vehicle has one.
7. Do not let the other end touch metal. Connect it to
the positive (+) terminal location of the vehicle with
the good battery. Use a remote positive (+)
terminal if the vehicle has one.
8. Now connect the black negative (−) cable to the
negative (−) terminal location of the vehicle with
the good battery. Use a remote negative (−) terminal
if the vehicle has one.
Do not let the other end of the cable touch anything
until the next step. The other end of the negative (−)
cabledoes notgo to the dead battery. It goes to
a heavy, unpainted metal engine part or to a remote
negative (−) terminal on the vehicle with the dead
battery.9. Connect the other end
of the negative (−)
cable to the
negative (−) terminal
location on the vehicle
with the dead battery.
Your vehicle has a
remote negative (−)
terminal marked
GND (−).
10. Now start the vehicle with the good battery and run
the engine for a while.
11. Try to start the vehicle that had the dead battery.
If it will not start after a few tries, it probably needs
service.
Notice:If the jumper cables are connected or
removed in the wrong order, electrical shorting may
occur and damage the vehicle. The repairs would
not be covered by your warranty. Always connect
and remove the jumper cables in the correct
order, making sure that the cables do not touch
each other or other metal.

Headlamp Aiming
Your vehicle has a visual optical headlamp aiming
system which may be equipped with horizontal aim
indicators. The aim has been preset at the factory and
should need no further adjustment. This is true even
though your horizontal aim indicators (if equipped) may
not fall exactly on the “0” (zero) marks on their scales.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the low beam
may be necessary if it is difficult to see lane markers
(for horizontal aim), or if oncoming drivers ash
their high beams at you (for vertical aim). If you believe
your headlamps need to be re-aimed, we recommend
that you take your vehicle to your dealer for service.
However, it is possible for you to re-aim your headlamps
as described in the following procedure.Adjustment screws can be turned with an E8 Torx
®
socket or T15 Torx®screwdriver.
Notice:To make sure your headlamps are aimed
properly, read all the instructions before beginning.
Failure to follow these instructions could cause
damage to headlamp parts.
The vehicle should be properly prepared as follows:
The vehicle should be placed so the headlamps are
25 ft. (7.6 m) from a light colored wall or other at
surface.
The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall
or other at surface.
The vehicle should be placed so it is perpendicular
to the wall or other at surface.
The vehicle should not have any snow, ice or mud
attached to it.
The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.
The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs (75 kg) on
the driver’s seat.
Tires should be properly inated.
