• Check to determine whether battery
replacement or resynchronization is
necessary.
See Section 2 of your Owner Manual.
Note:The RKE system will not operate
if the hood is open or if the key is in the
ignition.
PASS-Key®III Theft-Deterrent
System
Your vehicle is equipped with the
PASS-Key III theft-deterrent system,
which is a passive system that disables
the vehicle’s starter and fuel system if
someone attempts to start the vehicle
without the correct key.
During normal operation, the
(Security) light will turn off approximately
five seconds after the key is turned to
Run.
If the security light turns on while driving
and stays on, there may be a problem
with the PASS-Key III system. You will
be able to restart the engine if you turn
off the engine; however, your vehicle will
not be protected by PASS-Key III and
you should see your GM dealer.
See Section 2 of your Owner Manual.
Door Locks
Lockout Protection
This feature protects you from locking
the vehicle with the key in the ignition.
If the power door lock switch is pressed
when either the driver’s, passenger’s
or rear doors are open, all of the doors
will lock and then the driver’s door will
unlock. This feature does not include the
side cargo door.Cargo Door Relocking
This feature secures the side cargo
door after unloading cargo. If the side
cargo door is open when the Lock button
on the power door lock switch or the
Remote Keyless Entry transmitter is
pressed, all doors will lock and then
relock after the side cargo door is
closed. The side cargo door must be
closed within several minutes for the
relock to occur.
Security Locks (if equipped)
Security locks can be engaged on the
passenger-side rear door, the side
sliding door and the driver-side and
passenger-side 60/40 swing-out side
doors so that passengers can’t open the
doors from the inside.
To engage the security locks, move the
lever on the door to the (Lock) posi-

off as you start to drive. This could be
an early indicator that your tire pres-
sures are getting low and the tires need
to be inflated to the proper pressure.
See Section 5 of your Owner Manual.

Note: The Tire Pressure Monitor can
alert you about low tire pressure, but it
doesn’t replace normal monthly tire
maintenance.
The Duramax Diesel engine is equipped
with a Diesel Particulate Filter (DPF)
that will filter or trap particulates (solid
particles in the exhaust exhibited as
black smoke) before they can be emit-
ted into the atmosphere. The DPF will
occasionally need to be cleaned of
accumulated solids. During a cleaning,
the exhaust gas temperature is warmed
so that the accumulated particulate mat-
ter in the DPF will be safely converted to
harmless gases. This feature has been
designed to operate automatically, with
limited driver involvement.
For effective DPF cleaning, the vehicle
will need to operate continuously for
approximately 20 minutes and at speeds
greater than 30 mph. If the vehicle is
returned to idle during the cleaning
process, the driver may notice a slightly
different sound or a slightly elevated
engine idle speed. This is normal.
If the vehicle is not being operated in a
manner to allow effective automatic DPF
cleaning, the CLN EXH FILTER warning
lamp will illuminate.
See your Duramax Diesel Engine Owner
Manual for more information.

Oil Life System
The Oil Life System calculates engine
oil life based on vehicle use and
displays the CHANGE ENGINE OIL
SOON message when it’s necessary to
change your engine oil and filter. This is
based on engine operation and driving
conditions, not mileage. The Oil Life
System should be reset to 100% only
following an oil change.
To reset the Oil Life System:
1. Turn the ignition key to Run with the
engine off.
2. Fully press and release the accelera-
tor pedal slowly three times within
five seconds.
3. Turn the key to Lock.
See Section 5 of your Owner Manual.
