lock CHEVROLET SUBURBAN 1996 Manual Online

Then, without shutting off the engine, follow these steps:
1. Flip the handle up and then pull out the dipstick and wipe it with a
clean rag or paper towel.
2. Push it back in all the way, wait three seconds and then pull it back out
again.
3. Check both sides of the dipstick, and read the lower level. The fluid
level must be
in the COLD area for a cold check or in the HOT area or
cross-hatched area for a hot check.
4. If the fluid level is in the acceptable range, push the dipstick back in all
the way; then flip the handle down to lock the dipstick
in place.

How to Add Fluid
Refer to the Maintenance Schedule to determine what kind of transmission
fluid to use. See “Recommended Fluids and Lubricants”
in the Index.
Add fluid only after checking the transmission fluid HOT.
(A COLD check
is used
only as a reference.) If the fluid level is low, add only enough of the
proper fluid to bring the level up to the HOT area for a
hot check. It doesn’t
take much fluid, generally less than a
int. Don 7 overfill. We recommend
you
use only fluid labeled DEXRON -111, because fluid with that label is
made especially for your automatic transmission. Damage caused by fluid
other than DEXRON@-111
is not covered by your new vehicle warranty.

After adding fluid, recheck the fluid level as described under “How to
Check.”
When the correct fluid level is obtained, push the dipstick back in all
the way; then flip
the handle down to lock the dipstick in place.
Manual Transmission Fluid
When to Check
A good time to have it checked is when the engine oil is changed. However,
the fluid
in your manual transmission doesn’t require changing.
How to Check
Because this operation can be a little difficult, you may choose to have this
done at your
GM dealer Service Department.
If you do it yourself, be sure to follow all the instructions here, or you could
get a false reading.
I NOTICE:
Too much or too little fluid can damage your transmission. Too
much can mean that some of the fluid could come out and fall on
hot engine parts or exhaust system parts, starting a fire.
Be sure
to get an accurate reading if you check your transmission fluid.
Check the fluid level only when your engine is off, the vehicle is parked on
a level place and the transmission is cool enough for you to rest your fingers
on the transmission case.

Air Conditioning
Every now and then have your dealership check your air conditioning
system to be sure
it has not lost any cooling ability. If you think the system
is not working properly, have your dealership check it out as soon as
possible.
The air conditioning will not work when the temperature is below
40°F
(4°C).
Fluid Leak Check
After the vehicle has been parked for a while, inspect the surface under the
vehicle for water, oil, fuel or other fluids. Water dripping from the air
conditioning system after
it has been used is normal. If you notice fuel leaks
or fumes, the causes should be found and corrected at once.
Lock Cylinders
To be sure your locks operate properly, they must be lubricated. Your
vehicle’s maintenance schedule will tell
you how often to lubricate them.
See “Recommended Fluids and Lubricants”
in the Index for the proper
lubricant to use.
You should not use penetrating oils because they could wash out the factory
installed lubricant and cause the lock
to bind. De-icers which contain
alcohol could also wash away
the lubricant, so be sure to lubricate the lock
after using
a de-icer of this type.
Battery
Every new GM vehicle has a Delco Freedom’ battery. You never have to
add water
to one of these. When it’s time for a new battery, we recommend
a Delco Freedom@ battery. Get one that has the replacement number shown
on the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or more, take off the
black, negative
(-) cable from the battery. This will help keep your battery
from running down.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from short circuits by a
combination of fuses, circuit breakers, and fusible thermal links
in the
wiring itself. This greatly reduces the chance
of fires caused by electrical
problems. See “Fuses and Circuit Breakers”
in the Index for more
information.
Headlamps
The headlamp wiring is protected by a circuit breaker in the lamp switch.
An electrical overload will cause
the lamps to flicker on and off, or in some
cases to remain off. If this happens, have your headlamp wiring checked
right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit breaker and a fuse. If
the motor overheats due
to heavy snow, etc., the wiper will stop until the
motor cools. Although the circuit is protected from electrical overload,
overload due
to heavy snow, etc., may cause wiper linkage damage. Always
clear ice and heavy snow from the the windshield before using the
windshield wipers. If the overload
is caused by some electrical problem and
not snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power windows and other
power accessories. When the current load is
too heavy, the circuit breaker
opens and closes. This protects the circuit
until the current load returns to
normal
or the problem is fixed.
Trailer Wiring Harness
The seven-wire trailer wiring harness is protected by an in-line fuse in the
battery feed wire. This fuse is near the junction block. See “Trailer Wiring
Harness”
in the Index for more information.

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 Index for
more information.
