Cadillac 2004 CTS - Manual (Page 87)

To program a new key do the following:
1. Verify that the new key has PK3+ stamped on it.
2. Insert the current driver’s key in the ignition and start
the engine. If the engine will not start see your dealer
for service.
3. After the engine has started, turn the key to OFF,
and remove the key.
4. Insert the key to be programmed and turn it to ON
within ten seconds of removing the previous key.
5. The security light will turn off once the key has been
programmed. It may not be apparent that the security
light went on due to how quickly the key is
programmed.
6. Repeat the Steps 1 through 4 if additional keys are
to be programmed.
If you are ever driving and the security light comes on and
stays on, you will be able to restart your engine if you turn
it off. The theft-deterrent system, however, is not working
properly and must be serviced by your dealer. Your
vehicle is not protected by the theft-deterrent system at
this time.
In an emergency, contact Cadillac Roadside Assistance.

Roadside Service on page 7-6.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice: Your vehicle does not need an elaborate
“break-in.” But it will perform better in the long run
if you follow these guidelines for the first 500 miles
(805 km):
• Do not drive at any one speed — fast or slow.
• Do not exceed 70 mph (113 km/h).
• Do not make full-throttle starts; also refrain
from using the full throttle while driving.
If these procedures are not followed, your engine,
axle or other parts could be damaged.
Avoid making hard stops for the first 200 miles
(322 km) or so. During this time your new brake
linings are not yet broken in. Hard stops with new
linings can mean premature wear and earlier
replacement. Follow this break-in guideline every
time you get new linings.
Do not tow a trailer during break-in. See Towing a
Trailer on page 4-38 for more information.
