1995 GMC SIERRA door lock

Key in the Ignition
If you walk away from your vehicle with the keys inside, it’s an easy target
for joy riders or professional thieves
- so don’t do it.
When you park your vehicle and open the driver’s door, you‘ll hear a tone
reminding
you to remove your key from the ignition and take it with you.
Always do this.
Your steering wheel will be locked, and so will your
ignition. If you have
an automatic transmission, taking your key out also
locks your transmission. And remember to lock the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your vehicle. Remember
to keep
your valuables out of sight. Put them in a storage area, or take them
with
you.
Parking Lots
If you park in a lot where someone will be watching your vehicle, it‘s best
to lock
it up and take your keys. But what if you have to leave your ignition
key? What if
you have to leave something valuable in your vehicle?
Put your valuables in a storage area, like your glove box.
Lock all the doors except the driver’s.
New Vehicle “Break-In ”
NOTICE:
Your modern vehicle doesn’t need an elaborate “break-in.” But
it will perform better in the long run if you follow these
guidelines:
Keep your speed at 55 mph (88 km/h) or less for the first 500
miles (804 km).
Don’t drive at any one speed - fast or slow - for the first
500 miles
(804 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.

Don’t pause in NEUTRAL (N) as you shift the transfer case into 4-WHEEL
LOW (4L), or your gears could clash.
Remember that driving in
&WHEEL HIGH (4H) or 4-WHEEL LOW (4L) may
reduce fuel economy.
Also, driving in four-wheel drive on dry pavement could
cause your tires
to wear faster and make your transfer case harder to shift.
Front Axle Locking Feature
The front axle locks and unlocks automatically when you shift the transfer
case. Some delay for the axle to lock or unlock is normal. If the outside
temperature is very hot, or the vehicle has been used under hard driving
conditions, there may be a slight delay for the axle to unlock.
Windows
To open your manual
windows, turn the
hand crank on each
door to raise or lower
your side door
windows.
If you have the
optional power
windows, the controls
are on each of the side
doors.
The driver’s door has a switch for the passenger windows as well.
Your power
windows will work when the ignition has been turned to ACC or RUN.
Push the rear
of the switch with the power window symbol on it to lower the
window.
Push the front of the switch with the power window symbol on
it to raise the
window.

While refueling, hang
the cap inside the fuel
door.
To take off the cap, turn it slowly to the left (counterclockwise).
-~
A CAUTION:
If you get gasoline on yourself and then something ignites it, you
could be badly burned. Gasoline can spray out on you if you
1 open the fuel filler cap too quickly. This spray can happen if
your tank is nearly full, and
is more likely in hot weather. Open
the
fuel filler cap slowly and wait for any “hiss” noise to stop.
Then unscrew the cap all the way.
Be careful not to spill gasoline. Clean gasoline from painted surfaces as
soon as possible. See “Cleaning the Outside of Your Vehicle” in the Index.
When
you put the cap back on, turn it to the right until you hear a clicking
noise.
1 NOTICE:
If you need a new cap, be sure t.0 get the right type. Your dealer
can get one for you.
If you get the wrong type, it may not fit or
have proper venting, and your fuel tank and emissions system
might be damaged.

Fuse Block
The fuse block access
door is on the driver’s
side edge
of the
instrument panel.
Pull
off the cover to access
the fuse block.
You can remove fuses
with a fuse extractor.
The fuse extractor is
mounted to the fuse
block access door.
To remove fuses if you don’t have a fuse extractor, hold the end of the fuse
between your thumb and index finger and pull straight out.
Be sure to use the correct fuse. If you ever have a problem
on the road and
don’t have a spare fuse, you can “borrow” one
of the correct value. Just pick
some feature of your vehicle that
you can get along without-like the radio
or cigarette lighter-and use its fuse, if
it is of the value you need. Replace
it as soon as you can. See “Fuses and Circuit Breakers” in the Tndex for
more information.

in the Index for further details.
At Least Once a Year
Key Lock Cylinders
Lubricate the key lock cylinders with the lubricant specified in Part D.
Body Lubrication
Lubricate all fuel doors, body hood and body door hinges, tailgate and
tailgate handle pivot points, latches, locks, and folding seat hardware. Part

Starter Switch
A CAUTION:
When you are doing this check, the vehicle could move suddenly.
If it does, you or others could be injured. Follow the steps below.
1. Before you start, be sure you have enough room around the vehicle. It
should be parked
on a level surface.
2. Firmly apply both the parking brake (see “Parking Brake” in the Index
if necessary) and the regular brake.
NOTE: Do not use the accelerator pedal, and be ready to turn off the
engine immediately
if it starts.
3. On automatic transmission vehicles, try to start the engine in each gear.
The starter should work only
in PARK (P) or NEUTRAL (N). If the
starter works in any other position, your vehicle needs service.
On manual transmission vehicles, put the shift lever in NEUTRAL
(N),
push the clutch down halfway and try to start the engine. The starter
should work only when the clutch is pushed down
all the way to the
floor. If the starter works when the clutch isn’t pushed all the way
down, your vehicle needs service.
