1998 GMC ENVOY ignition

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:

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.

FIRST (1): This position gives you even more power
but lower fuel economy than SECOND (2). You can use
it on very steep hills, or in deep snow or mud. If the
selector lever
is put in FIRST (1) while the vehicle is
moving forward, the transmission won’t shift into
FIRST (1) 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 only the accelerator
pedal. This could overheat and damage the
transmission.
Use your brakes or shift into
PARK
(P) to hold your vehicle in position
on a hill.
Parking Brake
To set the parking brake. hold the regular brake pedal
down with your
right foot. Push down the parking brake
pedal with your left foot.
If the ignition is on, the brake
system warning light
will come on.
To release the parking brake, hold the regular brake
pedal down.
Pull the BRAKE RELEASE lever. It is located on the
bottom of the driver’s side of the instrument panel.

2. Move the shift lever into PARK (P) position
like this:
Hold in the button on the lever.
Push the lever all the way toward the front of
the vehicle.
3. Turn the ignition key to LOCK,
4. Remove the key and take it with you. If you can
leave your vehicle with the key, your vehicle
is in
PARK
(P).
Leaving Your Vehicle With the
Engine Running
It can be dangerous to leave your vehicle with the
engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P)
with the parking brake firmly set. And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don’t leave your vehicle with the
engine running unless you have to.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is firmly set before
you leave it. After
you’ve moved the shift lever into PARK
(P), hold the
regular brake pedal down. Then, see if you can move the
shift lever away from PARK
(P) without pressing the
button
on the shift lever. If you can, it means that the
shift lever wasn’t fully locked into PARK
(P).

Torque Lock Shifting Out of Park (P)
If you are parking on a hill and you don’t shift your
transmission into PARK (P) properly, the weight
of the
vehicle may put too much force on the parking pawl in
the transmission. You may find it difficult to pull the
shift lever out
of PARK (P). This is called “torque lock.”
To prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the
driver’s seat.
To find out how, see “Shifting Into PARK
(P)” in the Index.
When you are ready to drive, move the shift lever
out of
PARK (P)
before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill
to take some of the
pressure from the parking pawl in
the transmission, so
you can pull the shift lever out of PARK (P). Your
vehicle has
a Brake-Transmission Shift Interlock
(BTSI). You have to fully apply your regular brake
before you
can shift from PARK (P) when the ignition is
in RUN. See “Automatic Transmission Operation”
in
the Index.
If you cannot shift out of PARK (P), ease pressure on
the shift lever
-- push the shift lever all the way into
PARK
(P) as you maintain brake application. Then
move
the shift lever into the gear you want. You must
press the shift lever button on the console shift lever.
If
you ever hold the brake pedal down but still can’t
shift out
of PARK (P), try this:
1. Turn the key to OFF.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear
you want.
5. Have the vehicle fixed as soon as you can.

4LO: This setting also engages your front axle to give
you extra traction. You may never need 4LO. It sends
the maximum power to all four wheels.
You might
choose 4LO if you were driving off-road in sand, mud
or deep snow and climbing or descending steep hills.
Indicator lights in the switches show
you which setting
you are in. The indicator lights will come on briefly
when you turn on the ignition and one will stay on.
If the lights do not come on, you should take your
vehicle in for service. An indicator light will flash
while shifting. It will remain illuminated when the
shift is completed.
Shifting from 2HI to 4HI
Press and release the 4HI switch. This can be done at
any speed, and the front axle will lock automatically.
Shifting from 4HI to 2HI
Press and release the 2HI switch. This can be done at
any speed, and the front axle will unlock automatically.
Shifting from 2HI or 4HI to 4LO
To shift from 2HI or 4HI to 4L0, the vehicle must be
stopped
or moving less than 3 mph (4.8 kmh) with the
transmission
in NEUTRAL (N). The preferred method
for shifting into 4LO is to
have your vehicle moving 1 to
2 mph (1.6 to 3.2 kmh). Press and release the 4LO
switch. You must wait for the 4LO indicator light to stop
flashing and remain illuminated before shifting your
transmission into gear.
If the 4LO switch
is pressed when your vehicle is in
gear and/or moving,
the 4LO indicator light will flash
for
30 seconds and not complete the shift unless your
vehicle
is moving slower than 3 mph (4.8 kdh) and the
transmission is in NEUTRAL
(N).
If your transfer case does not shift into 4L0, your
transmission indicator switch may require adjustment.
With your transmission in NEUTRAL (N), press and
release the 4LO switch. While the 4LO indicator light
is
flashing, shift your transmission into PARK (P). Wait
until the 4LO indicator light remains illuminated before
shifting your transmission into gear. This will get you
into 4L0, but you should take your vehicle in for service
to restore normal operation.

Passing Another Vehicle While Using Cruise Control Exterior Lamps
Use the accelerator pedal to increase your speed. When
you take your foot off the pedal, your vehicle will slow
down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the hills.
When going up steep hills, you may want
to step on the
accelerator pedal to maintain your speed. When going
downhill, you may have to brake or shift to a lower gear
to keep your speed down.
Of course, applying the brake
takes you out of cruise control. Many drivers find this to
be too much trouble and don’t use cruise control on
steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:
Step lightly on the brake pedal.
Move the cruise control switch to OFF.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased. Your
parking lamp and headlamp switch is on the
driver’s side
of your instrument panel.
Rotate the
knob to the right to the parking lamps symbol
to manually turn on:
Parking Lamps
Sidemarker Lamps
Taillamps
License Plate Lamps
Instrument Panel Lights
