1998 GMC ENVOY Owners Manual

Remember, the theft-deterrent system won‘t activate if
you lock the doors with a key or use the manual door
lock. It activates only if
you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should
also remember that you
can start your vehicle with the correct ignition key
if’ the
alarm has been set
off.
Here’s how to avoid setting off the alarm by accident:
If you don’t want to activate the theft-deterrent
system, the vehicle should be locked
with the door
key
after the doors are closed.
Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking
a door any other
way will set off the alarm.
If you set off the alarm by accident, unlock any door
with the key. You can
also turn off the alarm by pressing
UNLOCK on the remote keyless entry transmitter.
The alarm won’t stop if you try to unlock a door any
other way.
Testing the Alarm
The alarm can be tested by following these steps:
I. From inside the vehicle, lower the driver‘s window
and open the driver’s door.
3.
4.
Activate the system by locking the doors with the
power door
lock switch while the door is open, or
with the remote keyless entry transmitter.
Get out
of the vehicle, close the door and wait for the
SECURITY light to
go out.
Then reach
in through the window, unlock the door
with the manual door lock and open the door. This
should set
off the alarm.
If the alarm does not sound when it should but the
vehicle’s high-beam headlamps flash, check
to see if the
horn works. The horn fuse may be blown.
To replace the
f~~se, see “Fuses and Circuit Breakers”
in the Index.
If the alarm does not sound or the vehicle’s high-beam
headlamps do not flash, the vehicle should be serviced
by
an authorized service center.
Passlock’
Your vehicle is equipped with the Passlock
theft-deterrent system.
Passlock is
a passive theft-deterrent system. The system
is armed once the key is removed from the ignition.
Passlock enables fuel
if the ignition lock cylinder is
turned with a valid key. If a correct key is not used, fuel
is disabled.

During normal operation, the SECURITY light will go
off after the engine is started.
If the engine stalls and the SECURITY light flashes,
wait about
10 minutes until the light stops flashing
before trying to restart the engine. Remember to release
the key from the
START position as soon as the
engine starts.
If the engine does not start after three (3) tries, the
vehicle needs service.
If you are driving and the SECURITY light comes on,
you will be able to restart the engine if you turn the
engine
off. However, your Passlock system is not
working properly and
must be serviced by your dealer.
Your vehicle is not protected by Passlock at this time.
You may also want to check the fuse (see ”FLIS~S and
Circuit Breakers”
in the Index). See your dealer
for service.
If the SECURITY light comes on while the engine is
running.
a problem has been detected and the system
may need service. See your dealer for service.

1-800-268-6800).
New Vehicle “Break-In”
NOTICE:
~~~ ~ ~
Your vehicle doesn’t need an elaborate
“break-in.” But it will perform better in the long
run if you follow these guidelines:
0
0
0
0
Keep your speed at 55 mph (88 kmh) or
less for the first
500 miles (805 km).
Don’t drive at any one speed
-- fast or
slow -- for the first 500 miles (805 km).
Don’t make full-throttle starts.
Avoid making hard stops for the first
200
miles (322 km) or so. During this time your
new brake linings aren’t yet broken in.
Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every
time you get new brake linings.
Don’t tow a trailer during break-in.
See “Towing a Trailer” in the Index for
more information.

Ignition Positions
Use the key to turn the ignition switch to
five different positions.
C
ACCESSORY (A): This position lets you use things
like the radio and
the windshield wipers when the
engine is
off. Push in the key and turn it toward you.
Your steering wheel will remain locked, just as it was
before you inserted the key.
I NOTICE:
Don’t operate accessories in the ACCESSORY
position for long periods
of time. Prolonged
operation
of accessories in the ACCESSORY
position could drain your battery and prevent
you from starting your vehicle.
LOCK
(B): This position locks your ignition, steering
wheel and transmission.
It’s a theft-deterrent feature.
You will only be able to remove your key when the
ignition is turned to LOCK.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. Use
OFF if you must have
your vehicle in motion while the engine is off (for
example, if your vehicle is being towed).
RUN (D): This is the position for driving.
START (E): This position starts your engine.

NOTICE:
If your key seems stuck in LOCK and you can’t
turn
it, be sure you are using the correct key; if
so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. But turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch.
If none of this works, then your
vehicle needs service.
Retained Accessory Power
Your vehicle is equipped with a Retained Accessory
Power (RAP) feature which will allow certain features
on your vehicle to continue to work up to
20 minutes
after the ignition key
is turned to OFF.
Your radio, power windows, sunroof and overhead
console will work when the ignition key is in RUN or
ACCESSORY. Once the key is turned from RUN to
OFF, these features will continue to work for up to
20 minutes or until a door is opened.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position -- that’s a
safety feature.
To restart when you’re already moving,
use NEUTRAL (N) only.
I 1
I NOTICE:
Don’t try to shift to PARK (P) if your vehicle is
moving.
If you do, you could damage the
transmission. Shift to
PARK (P) only when your
vehicle
is stopped.
1. Without pushing the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as your
engine gets warm.
2-15
ProCarManuals.com

I NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to be
drained much sooner. And the excessive heat can
damage your starter motor.
2. If it doesn’t start right away, hold your key in
START. If it doesn’t start in 10 seconds, push the
accelerator pedal
all the way down for five more
seconds, unless
it starts sooner.
3. If your engine still won’t start (or starts but then
stops), wait
15 seconds and start over.
When
the engine starts, let go of the key and the
accelerator pedal.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle.
If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don’t,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part of this manual that tells how to do it
without damaging your vehicle. See “Towing
Your Vehicle” in the Index.
Engine Coolant Heater (If Equipped)
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.
2-16
ProCarManuals.com

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is located on the driver’s side of the engine
compartment, behind the underhood fuse block.
3. Plug it into a normal, grounded 110-volt AC outlet.
% CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind
of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into
a properly grounded three-prong
110-volt
AC outlet. If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least
15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away from
moving engine parts. If you don’t, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind
of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

Automi ic Transmission Operation
There are several different positions for your shift lever.
PARK (P): This locks your rear wheels. It’s the best
position to use when you start your engine because your
vehicle can’t move easily.
It is dangerous to get out of your vehicle if the
shift lever is not fully in
PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don’t leave your vehicle when the engine is
running unless
you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured.
To be sure your
vehicle won’t move, even when you’re on fairly
level ground, always set your parking brake and
move the shift lever to
PARK (P).
See “Shifting Into PARK (P)” in the Index. If
you’re pulling
a trailer, see “Towing a Trailer” in
the Index.
Ensure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has
a
Brake-Transmission Shift Interlock (BTSI). You have to
fully apply your regular brakes before you can shift
from PARK (P) when the ignition key is
in RUN. If you
cannot shift out of PARK (P), ease pressure on the shift
lever
-- push the shift lever all the way into PARK (P)
(press
the button in on the console shift lever) as you
maintain brake application. Then move the shift lever
into the gear
you wish. See “Shifting Out of PARK (P)”
in the Index.
REVERSE (R): Use this gear to back up.
NOTICE:
Shifting to REVERSE (R) while your vehicle
is moving forward could damage your
transmission. Shift to
REVERSE (R) only
after your vehicle is stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transmission, see
“Stuck: In Sand, Mud, Ice or Snow”
in the Index.

ProCarManuals.com

NEUTRAL (N): In this position, your engine doesn’t
connect with the wheels.
To restart when you’re already
moving, use
NEUTRAL (N) only.
Shifting out of PARK (P) or NEUTRAL (N) while
your engine
is “racing” (running at high speed) is
dangerous. Unless your foot is firmly on the
brake pedal, your vehicle could move very rapidly.
You could lose control and hit people or
objects. Don’t shift out
of PARK (P) or
NEUTRAL (N) while your engine is racing.
ml
I NOTICE:
Damage to your transmission caused by shifting
out
of PARK (P) or NEUTRAL (N) with the
engine racing isn’t covered by your warranty. DRIVE
(D):
This position is for normal driving. If you
need more power for passing, and you’re:
0 Going less than about 35 mph (55 krdh), push your
accelerator pedal about halfway down.
Going about 35 mph (55 krdh) or more, push the
accelerator all the way down.
You’ll shift down
to the next gear and have more power.
DRIVE
(D) should not be used when towing a trailer,
carrying a heavy load, driving on steep hills, or for
off-road driving. Select THIRD
(3) when operating the
vehicle under any of these conditions.
THIRD (3): This position is also used for normal
driving, however it offers more power and lower fuel
economy than DRIVE (D).
You should use THIRD (3)
when towing a trailer, carrying a heavy load, driving on
steep hills or winding roads or for off-road driving.
SECOND (2): This position gives you more power but
lower fuel economy than
THIRD (3). You can use
SECOND
(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.
You can also use SECOND
(2) for starting your vehicle
from a stop
on slippery road surfaces.
