Transmitter Range
The transmitter range depends on your
vehicle and where you are standing. The
coupe
(A) has an antenna in the driver’s
door and one in the rear area. The
convertible
(B) has one antenna in each
door. The antennas do not require any
maintenance.
Range also depends on how you hold
the transmitter. For best performance,
when you come near your vehicle, hold
the transmitter straight up and down,
so
the keys hang down.
If the range seems to be decreasing,
check the battery
in the transmitter.
Range will decrease if the battery is
low. It will also decrease if more than
one transmitter is in the area. Don’t put
the transmitter in a metal container
because the transmitter won’t work.
Matching Transmitter(s) 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
?urchased through your dealer.
Remember to bring any remaining
:ransmitters 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
model -system. (General Motors offers
several different models of these
systems on their vehicles.) Each vehicle
can have only three transmitters
matched to it.
To match transmitters to your
vehicle:
1. Move all transmitters out of range.
2. Turn the ignition on.
3. Push “TRIP ODO’ on the Driver
Information Center twice.
4. Within five seconds press and hold
“FUEL INFO’ until the “PASSIVE
KEYLESS ENTRY” light comes on.
5. Turn the ignition off, but leave the
key in the ignition. The “PASSIVE
KEYLESS ENTRY” light should
begin to flash to show the system is
in programming mode.

PASS-Key@
Your vehicle is equipped with the
PASS-Key@ (Personalized Automotive
Security System) theft deterrent system.
PASS-Key@ is a passive theft deterrent
system. This means you don’t have to do
anything different to arm or disarm the
system. It works when you insert or
remove the key from the ignition.
PASS-Key@ uses a resistor pellet in
the ignition key that matches a decoder
in your vehicle. When the PASS-Key@ system
senses that
someone is using the wrong key, it shuts
down the vehicle’s starter and fuel
systems. For about three minutes,
the
starter won’t work and fuel won’t go to
the engine. If someone tries to start your
vehicle again or uses another key during
this time, the shutdown period will start
over again. This discourages someone
from randomly trying different keys with
different resistor pellets in an attempt to
make a match.
The ignition key must be clean and dry
before it’s inserted in
the ignition or the
engine may not start. If the “SECURITY”
light comes on, the key may be dirty or
wet.
If this happens and the starter won’t work,
turn the ignition off. Clean and dry
the
key, wait three minutes and try again. If
the starter still won’t work, wait three
minutes and
try the other ignition key. At
this time, you may also want to check
the
fuses (see “Fuses and Circuit Breakers’’ in
the Index). If the starter won’t work with the
other key, your vehicle needs service.
[f your vehicle does start, the first ignition
key may be faulty. See your Chevrolet
Jealer or a locksmith who can service the
PASS-Key@
However, if you accidentally use a key
that has
a damaged or missing resistor
pellet, you will see no “SECURITY”
light.
You don’t have to wait three
minutes before trying the proper key.
if the resistor pellet is damaged
OF
missing, the starter won’t work. Use the
other ignition key, and see your Chevrolet
dealer or a locksmith who can service the
PASS-Key@ to have a new key made.
If the “SECURITY” light comes on while
driving, have your vehicle serviced as
soon as possible.
If you lose or damage a PASS-Key@
ignition key, see your Chevrolet
dealer or a locksmith who can service
PASS-Key@. In an emergency, call the
Chevrolet Roadside Assistance Program
at
1 -800-CHEV USA (1 -800-243-8872).

Engine Power Switch (ZR-I)
The LT5 engine in your ZR-1 has two sets
of intake runners and fuel injectors. The
primary set can be run alone for normal
engine power, or both sets can be used
for
full engine power.
Full power gives you extra power for
highway touring and off-road sports use
and reserve power for passing. With
normal power, you’ll notice less engine
and exhaust noise. To
change the power setting, put your
engine power key into the switch. Turn
the key to the setting you want and let
go
The key will return to the center position.
Your ZR-1 is able to run at full power

(LTI ENGINE, CANADA)
In very cold weather, 0 “F (- 18 “C) or
colder, the engine coolant heater can help.
You’ll get easier starting and better fuel
economy during engine warm-up.
Usually, the coolant heater should be
plugged in a minimum of four hours prior
to starting your vehicle.
To use the coolant heater:
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
3. Plug it into a normal, grounded
1 10-volt outlet.
I NOTICE:
After you’ve used the coolant heater,

0 Automatic Overdrive
This position is for normal driving. If you
need more power for passing, and you’re:
- Going less than about 35 mph
(56 kmh), push your accelerator
pedal about halfway down.
- Going about 35 mph (56 km/h) or
more, push the accelerator all the way
down.
You’ll shift down to the next gear and
have more power.

Overdrive.
Here are some times
you might choose
“D’ instead of 0 :
- When driving on hilly, winding roads
- When going down a steep hill
2 (Second Gear)
This position gives you more power but
lower
fuel economy. You can use “2” on
hills. It can help control your speed as
you
go down steep mountain roads, but
then you would also want to use your
brakes
off and on.

more than
5 miles (8 km), or at
speeds over

Don’t shift into
“2” unless you are
going slower than
65 mph (1 05

This position gives you even more power
(but lower fuel economy) than
“2.” You
can use it on very steep hills, or in deep
snow or mud. If the selector lever is put
ir

gear until the vehicle is going slowly
enough.
NOTICE:
If your rear wheels can’t rotate, don’t
try to drive. This might happen if you
were stuck in very deep sand or mud
or were up against a solid object. You
could damage your transmission.
Also, if you stop when going uphill,
don’t hold your vehicle there with
