1998 GMC ENVOY Owners Manual

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

Rotate the knob to the right to the master lamps symbol
to turn on all the lamps listed as well as
the headlamps.
Rotate the
knob all the way to the left to turn off your
lamps and put the system in automatic headlamp mode.
Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as the
taillamps, sidemarker, parking lamps and the instrument
panel lights. The radio lights will also be dim.
Your vehicle is equipped with High Intensity Discharge
(€€ID) headlamps. Your headlamps come on at lower
intensity and gradually increase to full brightness.
Your vehicle is equipped with
a light sensor on the top
of the instrument panel under the radio speaker grille,
so
be sure it is not covered, which will cause the system to
be on whenever the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather, a tunnel or fueling your vehicle in a low-light
area. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running Lamps
(DRL) and the automatic headlamp systems
so that driving under bridges or bright overhead street lights
does not affect the system. The DRL and automatic
headlamp system will only be affected when the light
sensor
sees a change in lighting lasting longer than
the delay.
To idle your vehicle with the automatic headlamp
system
off, set the parking brake while the ignition is
off. Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Lamps On Reminder
A reminder chime will sound when your headlamps or
parking lamps
are manually turned on and your ignition
is in
OFF, LOCK or ACCESSORY. To disable the
chime, rotate the thumb wheel all the way down. In
the
automatic mode, the headlamps turn off once the
ignition key is in
OFF,
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short periods after dawn and before sunset.

The DRL system will make your high-beam headlamps
come
on at reduced brightness when:
Fog Lamps
the ignition is on,
the headlamp switch is in automatic headlamp
mode and
the parking brake is released.
When the DRL are on, only your high-beam headlamps
will be on. The taillamps, sidemarker and other lamps
won’t be on. The instrument panel won’t be lit up either.
When it begins to get dark, the high-beam headlamps
will automatically switch from DRL to the regular
low-beam headlamps.
When you turn
the headlamp switch off, the regular
low-beam headlamps will
go off, and your high-beam
headlamps will change to the reduced brightness
of DRL
provided it is not dark outside.
To idle your vehicle with
the DRL off, set the parking
brake. The DRL will stay off until
you release the
parking brake.
As with any vehicle, you should turn on the regular
headlamp system
when you need it. Use your fog lamps
for better vision in foggy or misty
conditions. Your low-beam headlamps or your parking
lamps must be on for your fog lamps to work.
The fog lamp switch is
on the instrument panel under
the lamps switch. Press
the switch to turn the fog lamps
on. Press the switch again to turn them
off. A light will
glow in
the switch when the fog lamps are on.
Remember,
fog lamps alone will not give off as much
light as your headlamps. Never use your fog lamps in
the dark without turning on your headlamps.
The
fog lamps will go off whenever your high-beam
headlamps come on. When the high beams
go off, the
fog lamps will come on again.

Battery Run-Down Protection
This feature shuts off the dome, courtesy, vanity,
reading, glove
box and underhood lamps if they are left
on for more than
20 minutes when the ignition is off.
This will keep your battery from running down.
If the battery run-down protection shuts off the interior
lamps, it may be necessary to do one of the following to
return
to normal operation:
0 Shut off all lamps and close all doors, or
Turn the ignition key to RUN.
This mirror automatically changes to reduce glare from
headlamps behind you. A photocell on
the back of the
mirror senses when it is becoming dark outside. Another
photocell
built into the mirror surface senses when
headlamps are behind you.
At night, when the glare is too high, the mirror will
gradually darken
to reduce glare (this change may take a
few seconds). The mirror will return to its clear daytime
state when the glare
is reduced. The vehicle will also
return to its clear daytime state when the vehicle is put
into
REVERSE (R).

Press the OFF AUTO button at the base of the mirror to
turn on the automatic feature. The button has
an
indicator light to show it is on. Press the OFF AUTO
button to turn the automatic feature
off.
Time Delay
The automatic mirror has a time delay feature which
prevents unnecessary switching from the night back to
the day position. This delay prevents rapid changing of
the mirror as you drive under lights and through traffic.
Cleaning the Photocells
Use a cotton swab and glass cleaner to clean the
photocells when necessary. The
control is located on the
driver’s door armrest.
Move the upper control to the left or right to choose the mirror, then press the
arrows on the control pad to adjust
the mirror.

A convex mirror can make things (like other
vehicles)
look farther away than they really are.
If you cut
too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder before
changing lanes.
4 Overhead Console
Heated Outside Rearview Mirror
When you operate the rear window defogger, a defogger
also warms the heated driver’s and passenger’s outside
rearview mirrors
to help clear them of ice and snow.
See “Rear Window Defogger” in the Index for
more information. The
overhead console includes reading lamps, a driver
information system,
a storage compartment for
sunglasses and a universal transmitter.

Reading La ~ ~ ps
Press the button near each
lamp to turn the reading
lamps
on and off.
The lamps can also be swiveled
to point in the
desired direction.
Driver Information System
This system displays the outside air temperature,
compass direction and trip information in the
overhead console.
USMET The USMET (United Statedmetric) button
allows you to switch the display between
the English
and metric system.
MODE: The MODE button can be used to toggle
between three modes
of operation: OFF, COMP/TEMP
and TRIP.
OFF: This button turns the system off.
COMP/TEMP: The display provides the outside
temperature and one
of eight compass readings to
indicate the direction the vehicle is facing.
Before you turn on the ignition and move
the vehicle,
the temperature indicated will be the last outside
temperature recorded with the ignition on. If the outside
temperature is
37°F (3°C) or lower, the display will
toggle between the word ICE and the current
temperature every eight seconds. This is a warning
to
the driver that road conditions may be icy, and that
appropriate precautions should be taken.
The compass is self-calibrating,
so it does not need to be
manually set. However, if C (Calibration) is displayed, the
compass will need
to be calibrated. You may also place the
compass in a noncalibrated mode by pressing and holding
the MODE and USMET buttons simultaneously while in
the COMPREMP mode. After about 10 seconds, the
compass will display
C and you can release the buttons.
Drive
the vehicle in a complete 360" circle three times at
a speed of less than 5 mph (8 km/h), and the compass will
function normally. Once the calibration is complete, the
display will return
to a compass reading.
