1998 CHEVROLET ASTRO ECU

Downloaded from www.Manualslib.com manuals search engine Include an ice scraper, a small brush or broom, a supply
of windshield washer fluid, a rag, some winter outer
clothing, a small shovel, a flashlight, a red cloth and
reflective warning triangles. And, if
you will be driving
under severe conditions, include a small bag
of sand, a
piece of old carpet or a couple of burlap bags to help
provide traction. Be sure you properly secure these
items in your vehicle.
Driving ‘---3w or Ice
Most of the time, those places where your tires meet the
road probably have good traction.
However, if there is snow or ice between your tires and
the road,
you can have a very slippery situation. You’ll
have a lot less traction or “grip” and will need to be
very careful.
What’s the worst time for this? “Wet ice.” Very cold
snow or ice can
be 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.

Do not load your vehicle any heavier than the
GVWR, or either the maximum front or rear GAWR.

break, or it can change the way your vehicle
handles. These could cause you to lose control.
Also, overloading can shorten the life of
your vehicle.
Using heavier suspension components to get added
durability might not change your weight ratings.

Downloaded from www.Manualslib.com manuals search engine Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with
the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are
driving is now a good deal longer and
not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand
to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without
a trailer. This
can help
you avoid situations that require heavy braking
and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal \
longer, you’ll need to go much farther beyond the
passed vehicle before
you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to
the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up slowly and, if
possible, have someone guide you.

Try to have a GM dealer or a professional towing
service tow your vehicle. They can provide the right
equipment and know how
to tow it without damage.
See “Roadside Assistance” in the Index.
If
your vehicle has been changed or modified since
it was factory-new by adding aftermarket items like
fog lamps, aero skirting, or special tires and wheels,
these things can be damaged during towing.
Before you do anything, turn
on the hazard

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
A vehicle can fall from a car carrier if it isn’t
adequately secured. This can cause
a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains or
steel cables before
it is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath the towed vehicle.
When your vehicle is being towed, have the ignition
key in the
OFF position. The steering wheel should
be clamped in a straight-ahead position, with a
clamping device designed for towing service. Do not
use the vehicle’s steering column lock for this. The
transmission should be in NEUTRAL
(N) and the
parking brake released.
I I
If your vehicle has the all-wheel-drive option, it can
only be towed with all four wheels
off the ground.
A dolly must be used under the unraised wheels
when towing or the vehicle must be transported on a
flat bed carrier.
Don’t have your vehicle towed with the wheels in
contact with the ground
if it has all-wheel drive. If
a vehicle with all-wheel drive must be towed with
sling-type or wheel-lift equipment, then either the
front or rear wheels must be supported on a dolly.
NOTICE:
If your vehicle has all-wheel drive, do not have
it towed with the wheels in contact with the
ground or vehicle damage may occur.
