five seconds, all the doors will unlock. Press the rear
door
UNLOCK button to unlock the rear door only.

Matching Transmitterfs) To Your Vehicle
Each key chain transmitter is coded to prevent another transmitter from
unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring any remaining
transmitters with you when
you go to your dealer. When the dealer matches
the replacement transmitter
to your vehicle, the remaining transmitters must
also be matched. Once the new transmitter
is coded, the lost transmitter will
not unlock your vehicle.
You can match a transmitter to as many different vehicles as you own,
provided they are equipped with
exactly the same 17ZOdd system. (General
Motors offers several different models
of these systems on their vehicles.)
Each vehicle can have
only two transmitters matched to it.
See your dealer to match transmitters to another vehicle.
Battery Replacement
Under normal use, the batteries in your key chain transmitter should last
about two years.
You can tell the batteries are weak
if the transmitter won’t work at the
normal range in any location. If you have to get close to your vehicle before
the transmitter works,
it’s probably time to change the batteries.
Use two Duracell@ type
DL2016, or a similar type.

lf Your Diesel Engine Won’t Start
If you’ve run out of fuel, look at “Running Out of Fuel” (see “Diesel Fuel
Requirements and Fuel System” in the Index).
If you’re
not out of fuel, and your engine won’t start, do this:
Turn your ignition
key to RUN. Make sure that the GLOW PLUGS light is
out. Then IMMEDIATELY
turn the ignition key to START.
If the light doesn’t go off, wait a few seconds, then try starting your engine
again. And, see your dealer
as soon as you can for a starting system check.
If the light comes
on and then goes off and you know your batteries are
charged, but your engine still
won’t start, your vehicle needs service.
If the light does
not come on when the engine is cold, your vehicle needs
service.
If your batteries don’t have enough charge to start your engine, see
“Battery”
in the Index.
Be sure you have the right oil for your engine, and that you’ve changed
the
oil at the proper times. If you use the wrong oil, your engine may be harder
to start.
If the engine starts, runs a short time, then stops, your vehicle needs service.
