lock GMC SIERRA 1995 Repair Manual

A CAUTION:
Driving to the top (crest) of a hill at full speed can cause an
accident. There could be a drop-off, embankment, cliff, or even
another vehicle. You could be seriously injured
or killed. As you
near the top
of a hill, slow down and stay alert.
Q: What should I do if my vehicle stalls, or is about to stall, and I
A: If this happens, there are some things you should do, and there are
some things you must not do. First, here’s what you
shoclld do:
can’t make it up the hill?
0 Push the brake pedal to stop the vehicle and keep it from rolling
backwards. Also, apply the parking brake.
If your engine is still running, shift the transmission into reverse,
release the parking brake, and slowly back down the
hill in reverse.
If your engine has stopped running, you’ll need to restart it. With the
brake pedal depressed and the parking brake still applied, shift the
transmission to PARK (P) (or, shift to NEUTRAL
(N) if your vehicle
has a manual transmission) and restart the engine. Then, shift
to
reverse, release the parking brake, and slowly back down the hill as
straight
as possible in reverse.
0 As you are backing down the hill, put your left hand on the steering
wheel at the
12 o’clock position. This way, you’ll be able to tell if your
wheels are straight and maneuver
as you back down. It’s best that you
back down the hill with your wheels straight rather than in the left or
right direction. Turning the
wheel too far to the left or right will
increase the possibility
of a rollover.
Here are some things you
must mt do if you stall, or are about to stall,
when going
up a hill.
0 Never attempt to prevent a stall by shifting into NEUTRAL (N) (or
depressing the clutch,
if you have a manual transmission) to ”rev-up”
the engine and regain forward momentum. This won’t work. Your
vehicle will roll backwards very quickly and
you could go out of
control.

What’s
the worst time for this? “Wet ice.” Very cold snow or ice can
slick and hard to drive
on. But wet ice can be even more trouble because it
may offer the least traction of all. You can get “wet ice” when it’s about
freezing
(32°F; OOC) and freezing rain begins to fall. Try to avoid driving
on wet ice until salt and sand crews can get there.
Whatever the condition
- smooth ice, packed, blowing or loose snow -
drive with caution.
Accelerate gently. Try not to break the fragile traction.
If you accelerate too
fast, the drive wheels will spin and polish the surface under the tires even
more.
Your anti-lock brakes improve your ability
to make a hard stop on a
slippery road. Even though you have an anti-lock braking system, you’ll
want to begin stopping sooner than you would on dry pavement. See
“Anti-Lock”
in the Index.
Allow greater following distance on any slippery road.
Watch for slippery spots. The road might be fine until you hit a spot
that’s covered with ice.
On an otherwise clear road, ice patches may
appear in shaded areas where the sun can’t reach: around clumps of
trees, behind buildings, or under bridges. Sometimes the surface
of a
curve or an overpass may remain icy when the surrounding roads are
clear. If
you see a patch of ice ahe.ad of you, brake before you are on it.
Try not to brake while you’re actually on the ice, and avoid sudden
steering maneuvers.

If You’re Caught in a Blizzard
k
I ....- -’
If you are stopped by heavy snow, you could be in a serious situation. You
should probably stay with your vehicle unless you know for sure that you
are near help and
you can hike through the snow. Here are some things to do
to summon help and keep yourself and your passengers safe: Turn on your
hazard flashers. Tie
a red cloth to your vehicle to alert police that you’ve
been stopped by the snow.
Put on extra clothing or wrap a blanket around
you.
If you have no blankets or extra clothing, make body insulators from
newspapers, burlap bags, rags, floor mats
- anything you can wrap around
yourself
or tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
-
A CAUTION:
Snow can trap exhaust gases under your vehicle. This can cause
deadly
CO (carbon monoxide) gas to get inside. CO could
overcome you and kill you.
You can’t see it or smell it, so you
might not know it is in your vehicle. Clear away snow from
around the base of your vehicle
, especially any that is blocking
your exhaust pipe.
And check around again from time to time to
be sure snow doesn’t collect there.
Open a window just
a little on the side of the vehicle that’s away
from the wind. This
will help keep CO out.

c
Run your engine only as long as you must. This saves fuel. When you run
the engine, make
it go a little faster than just idle. That is, push the
accelerator slightly. This uses less fuel for the heat that
you get and it keeps
the battery (or batteries) charged. You will need a well-charged battery (or
batteries) to restart the vehicle, and possibly for signaling later on with your
headlights. Let the heater run for awhile.
If you have a diesel engine, you may have to run it at a higher speed to get
enough heat. Then, shut the engine off and close the window almost all the
way
to preserve the heat. Start the engine again and repeat this only when
you feel really uncomfortable from the cold. But do it as little as possible.
Preserve the fuel as long
as you can. To help keep warm, you can get out of
the vehicle and do some fairly vigorous exercises every half hour or so until
help comes.
Power Winches
If you wish to use a power winch on your vehicle, only use it when your
vehicle
is stationary or anchored.
NOTICE:
Using a power winch with the transmission in gear may damage
the transmission. When operating a power winch, always leave
the transmission in NEUTRAL
(N).
Use the regular brakes, set the parking brake, or block the wheels to keep
your vehicle
from rolling.
