1998 CHEVROLET EXPRESS tires

Downloaded from www.Manualslib.com manuals search engine If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
1 .) Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transmission. These parts can work
hard on
mountain roads.
0 Know how to go down hills. The most important
thing to know is this: let your engine do some of the
slowing down. Shift to a lower gear when you go
down a steep or long hill.
If you don’t shift down, your brakes could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down a hill.
You could crash.
Shift down to let your engine
assist your brakes on
a steep downhill slope. Coasting downhill
in NEUTRAL (N) or
with the
ignition
off is dangerous. Your brakes will have to
do
all the work of slowing down. They could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down
a hill.
You could crash. Always have your engine running
1 and your vehicle in gear when you go downhill.

Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine and transmission, and you can climb the
hill better.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Don’t swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.
As you go over the top of a hill, be alert. There could be
something in your lane, like a stalled car or an accident.
You may see highway signs
on mountains that warn of
special problems. Examples
are long grades, passing or
no-passing zones, a falling rocks area or
winding
roads. Be alert to these and take appropriate action.

Here are some tips for winter driving:
Have your vehicle in good shape for winter. 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 on Snow 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.
0 You may want to put winter emergency supplies in
your vehicle.

Downloaded from www.Manualslib.com manuals search engine 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. 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 vehicle’s stability
when you 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 ahead of you, brake before you
are on it. Try not to brake while you’re actually on
the ice, and avoid sudden steering maneuvers.

COLD TIRE PRESSURE
The Certificationrnire label is found on the rear edge of
the driver's door. The label shows the size
of your
original tires and the inflation pressures needed to obtain
the gross weight capacity of your vehicle. This is called
GVWR (Gross Vehicle Weight Rating). The GVWR
includes the weight of the vehicle, all occupants, fuel
and cargo. The
Certificatioflire label also tells you the maximum
weights for the front and rear axles, called
Gross Axle
Weight Rating (GAWR).
To find out the actual loads on
your front and rear axles, you need to go to a weigh
station and weigh your vehicle. Your dealer can help
you with
this. Be sure to spread out your load equally on
both sides of the centerline.
Never exceed the GVWR for your vehicle, or the
GAWR
for either the front or rear axle.
And, if you do have a heavy load, you should spread
it out.
I
I
A QUI 0 :
Do not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
GAWR. If you do, parts on your vehicle can 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.

Downloaded from www.Manualslib.com manuals search engine You should use DRIVE (D) (or, as you need to, a
lower gear) when towing a trailer. Operating your
vehicle
in DRIVE (D) when towing a trailer will
minimize heat buildup and extend the
life of your
transmission.
Three important considerations have to do with weight:
0 the weight of the trailer,
the weight of the trailer tongue
and the weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull a
trailer are all important. And, it can also depend
on any
special equipment that you have
on your vehicle.
The following chart shows
how much your trailer can
weigh, based upon vehicle model and options. GlOOOO

Be sure your vehicle’s tires are inflated to the upper
limit for cold tires. You’ll find these numbers on the
Certification label at the rear edge of the driver’s door or
see “Tire Loading” in the Index. Then be sure you don’t
go over the
GVW limit for your vehicle, including the
weight of the trailer tongue.

It’s important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough roads are a
few reasons why you’ll need the right hitch. Here are
some rules to follow:
1 The bumpers on your vehicle are not intended for
hitches.
Do not attach rental hitches or other
bumper-type hitches to them. Use only a
frame-mounted hitch that does not attach to the
bumper.
Do not use a ball hitch, because it could pull
the bumper loose.
0 If you’ll be pulling a trailer that, when loaded, will
weigh
more than 4,000 lbs. (1 800 kg), be sure to use
a properly mounted, weight-distributing hitch and
sway control of the proper size.
This equipment is
very important for proper vehicle loading and good
handling when you’re driving.
0 Will you have to make any holes in the body of your
vehicle when
you install a trailer hitch?
If you’re using the wiring provided by the
factory-installed hitch, you should not need to make
any holes in the body of your vehicle. However, if
you have an aftermarket hitch installed, you may
need to make holes in the body.
If
you do, then be sure to seal the holes later when
you remove the hitch. If you don’t seal them, deadly
carbon monoxide (CO) from your exhaust can get
into your vehicle (see “Carbon Monoxide” in the
Index). Dirt and water can, too.

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.

Towing Your Vehicle
Try to have your 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 your Index.
If your vehicle has been changed since it was
factory-new, by adding things like fog lamps, aero
skirting, or special tires and wheels, these things could
be damaged during towing.
Before you do anything, turn
on the hazard
warning flashers.
When
you call, tell the towing service:
0 That your vehicle has rear-wheel drive.
0 The make, model and year of your vehicle.
0 Whether you can move the shift lever for
the transmission.
0 If there was an accident, what was damaged.
