1998 CHEVROLET ASTRO check engine light

Downloaded from www.Manualslib.com manuals search engine The most important advice on freeway driving is: Keep
up with traffic and keep
to the right. Drive at the same
speed most of the other drivers are driving. Too-fast or
too-slow driving breaks a smooth traffic flow. Treat the
left lane
on a freeway as a passing lane.
At the entrance, there is usually a ramp that leads to the
freeway.
If you have a clear view of the freeway as you
drive along the entrance ramp, you should begin
to
check traffic. Try to determine where you expect to
blend with the flow. Try to merge into the gap at close to
the prevailing speed. Switch
on your turn signal, check
your mirrors and glance over your shoulder as often as
necessary. Try to blend smoothly with the traffic flow.
Once you are on the freeway, adjust your speed to the
posted limit or to the prevailing rate if it’s slower. Stay
in the right lane unless
you want to pass.
Before changing lanes, check your mirrors. Then use
your turn signal.
Just before
you leave the lane, glance quickly over your
shoulder to make sure there isn’t another vehicle in your
“blind” spot.
Once
you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower
at night. When
you want
to leave the freeway, move to the proper
lane well in advance. If you miss your exit, do not,
under any circumstances, stop and back up. Drive
on to
the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according
to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds,
you may tend to think you are going
slower than
you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
-- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes
you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to go. If it needs
service, have it done before starting out. Of course,
you’ll find experienced and able service experts in GM
dealerships all across
North America. They’ll be ready
and willing to help
if you need it.

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.
Sr Y can trap exha. ler your vehicle.
~ This can cause deadly 60 (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.
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 charged. You will need a well-charged battery
to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let
the heater run for a while.
You can run the engine to keep warm, but be careful.

When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often
to check the lubricant and when to change it. See
“Scheduled Maintenance Services” in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level to the bottom
of the filler plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant
to use. See “Recommended Fluids and
Lubricants” in the Index.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant
is designed
to remain in your vehicle for
5 years or 150,000 miles
(240
000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem with
engine overheating,
see “Engine Overheating” in
the Index.
A 50/50 mixture of water and DEX-COOL@
coolant will:
Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265 “F ( 129°C).
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
B
they should.
