1998 GMC ENVOY Owners Manual

Shifting from 4LO to 4HI or 2HI
To shift from 4LO to 4H1 or 2H1, your vehicle must be
stopped or moving less than
3 mph (4.8 kdh) with the
transmission in NEUTRAL
(N). The preferred method
for shifting out of 4LO is to have your vehicle moving
1 to 2 mph (1.6 to 3.2 kdh). Press and release the 4HI
switch.
You must wait for the 4H1 indicator light to stop
flashing and remain illuminated before shifting your
transmission into gear.
If the 4HI switch is pressed when your vehicle is in gear
and/or moving, the 4HI indicator light will flash for
30 seconds but not complete the shift unless the vehicle
is moving slower than 3 mph (4.8 kmh) and the
transmission
is in NEUTRAL (N).
If your transfer case does not shift into 4H1, your
transmission indicator switch may require adjustment.
With your transmission in NEUTRAL
(N), press and
release the 4HI switch. While the 4HI indicator light is
flashing, shift your transmission into PARK
(P). Wait
until the 4HI indicator light remains illuminated before
shifting your transmission into gear. This will get you
into 4H1, but you should take your vehicle
in for service
to restore normal operation.

Turn and Lane Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow
you to signal a turn or a lane change.
To signal a turn, move the lever all the way up
or down. When the turn
is finished, the lever
will return automatically.
I 1 I An arrow on the instrument
panel will flash
in the
direction of the turn or
lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by
itself when you release it.
The signal indicator will flash even if a turn signal bulb
is burned out. Check the front and rear turn signal lamps
regularly
to make sure they are working. If
a bulb is burned out, replace it to help avoid an
accident. If the
arrows don’t go on at all when you
signal a turn, check the fuse (see “Fuses and Circuit
Breakers”
in the Index) and for burned-out bulbs.

to low, pull the multifunction lever all the way toward
you. Then release
it.
When the high beams are
on, this indicator light on
the instrument panel will
also be on.

Windshield Wipers
You control the windshield wipers by turning the band
with the wiper symbol on
it.
For a single wiping cycle, turn the band to MIST. Hold
it there until the wipers start, then let go. The wipers will
stop after one wipe. If you want more wipes, hold the
band on
MIST longer.
You can set the wiper speed for a long or short delay
between wipes. This
can be very useful in light rain or
snow. Turn the band to choose the delay time. The
closer to
LO, the shorter the delay. For steady wiping at
low speed, turn the band away
from you to the
LO position. For high-speed wiping,
turn the band further,
to HI. To stop the wipers, move
the band
to the OFF position.
Be sure to clear ice and snow from the wiper blades
before using them.
If they’re frozen to the windshield,
carefully loosen
or thaw them. If your blades do become
worn or damaged, get new blades or blade inserts.
Windshield Washer
There is a paddle marked with the windshield washer
symbol at the top
of the multifunction lever. To spray
washer fluid on the windshield, push the paddle. The
wipers
will clear the window and then either stop or
return to your preset speed.
In freezing weather, don’t use your washer until
the windshield is warmed. Otherwise the washer
fluid can
form ice on the windshield, blocking
your vision.

Rear Window Washermiper
To turn the rear wiper on, slide the switch to either LO
or HI. To turn the wiper off, slide the switch to OFF.
To wash the window, press the wash button located on
the switch.
The switch must be in either LO or HI.
The rear window washer uses the same fluid bottle as
the windshield washer. However, the rear window
washer will run out of fluid before the windshield
washer.
If you can wash your windshield but not your
rear window, check your fluid level.
Cruise Control
With cruise control, you can
maintain a speed
of about
25 mph (40 km/h) or more
without keeping your foot
on the accelerator. This can
really help on long trips.
Cruise control does not
work at speeds below about
25 mph (40 kmh).
If you apply your brakes, the cruise control
will disengage.

CAUTION:

Cruise control can be dangerous where you
can’t drive safely
at a steady speed. So,
don’t use your cruise control on winding
roads
or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don’t
use cruise control on slippery roads.
I ,A CAUTION: I
If you leave your cruise control switch on when
you’re not using cruise, you might hit a button
and go into cruise when
you don’t want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use it.
1. Move the cruise control switch to ON.
2. Get up to the speed you want.
3. Press in the SET button
at
the end of the lever
and release it.
4. Take your foot off the accelerator pedal.

Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course,
disengages the cruise control. But you don’t need to
reset it.
Once you’re going about
25 mph (40 km/h) or more,
you can move the cruise
control switch from
ON to
R/A for about a half
a second.
You’ll go right back up to your chosen speed and stay there.
If you hold the switch at FUA longer than half a second,
the vehicle will keep going faster until you release the switch or apply the brake.
So unless you want to go
faster, don’t hold the switch at
R/A.
Increasing Speed While Using Cruise Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher speed.
Press the SET button at the end
of the lever, then
release the button and the accelerator pedal. You’ll now cruise at the higher speed.
0 Move the cruise switch from ON to FUA. Hold it
there until you get up to the speed you want, and
then release the switch. To increase your speed in
very small amounts, move the switch to
R/A for less
than half a second. Each time you do this, your
vehicle will go about
1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise Control
Press and hold the SET button at the end of the lever
until you reach the lower speed you want, then release it.
To slow down in very small amounts, press the SET
button for less than half a second. Each time you do this, you’ll go
1 mph (1.6 km/h) slower.
