Downloaded from www.Manualslib.com manuals search engine Driving On a Long nip
Although most long trips today are made on freeways, there are still many
made on regular highways.
Long-distance driving on freeways and regular highways is the same in some
ways. The trip has to be planned and the vehicle prepared, you drive at
higher-than-city speeds, and there are longer turns behind the wheel. You’ll
enjoy your trip more
if you and your vehicle are in good shape. Here are
some tips for a successful long trip.
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.
Here are some things you can check before a trip:
Windshield Washer Fluid: Is the reservoir full? Are all windows clean
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked all levels?
Lights: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe, trouble-free trip. Is the tread
good enough for long-distance driving? Are the tires all inflated to the
recommended pressure?
Should you delay your trip a short time to avoid a major storm system?
inside and outside?
Weather Forecasts: What’s the weather outlook along your route?
Maps: Do you have up-to-date maps?
On the Road
Unless you
are the only driver, it is good to share the driving task with
others. Limit turns behind the wheel to about
100 miles (160 km) or two
hours- at a sitting. Then, either change drivers or stop for some refres\
hment
like coffee, tea or soft drinks and some limbering up. But
do stop and move
around. Eat lightly along the way. Heavier meals tend to make some people
sleepy.

A Adding only plain water to your cooling system can be dangerous.
Plain water, or some other liquid like alcohol, can boil before the
proper coolant mix
will. Your vehicle’s coolant warning system is set
for the proper coolant mix. With plain water or the wrong mix, yo\
ur
engine could get too hot but you wouldn’t get the overheat \
warning.
Your engine could catch fire and you or others could be burned. Use
~ cold weather, water can freeze and crack the engine, radiator, heater
‘e and other parts. Use the recommended coolant.
I CAUTION
A You can be burned if you spill coolant on hot engine parts. Coolant
enough. Don’t spill coolant on a hot engine.
b contains ethylene glycol and it will burn if the engine parts are hot
Vwn the coolant in the coolant recovery tank is at or above FULL, start
your vehicle.

Hood Latches and Hood Hinge
The Maintenance Schedule will tell you how often to lubricate the hood latch
and hood hinge assembly. See “Recommended Fluids and Lubricants”\
in the
Index for the proper lubricant
to use.
Propeller Shaft Slip Splines/Universal Joints
The Maintenance Schedule will tell you how often the slip splines must be
lubricated. See “Recommended Fluids and Lubricants” in the \
Index for the
proper lubricant
to use.
Constant Velocity Joints (All- Wheel Drive Only)
The Maintenance Schedule will tell you how often to lubricate the the
constant velocity joints. See “Recommended Fluids and Lubrican\
ts” in the
Index for the proper lubricant
to use.
Sliding Door Tracks
Your vehicle’s sliding door has three tracks which need lubricatio\
n.
For the upper and lower tracks, open the door, wipe the track\
clean and then
lubricate with Lubriplate@ White Grease.
For the outside middle track, close the door after you finish \
the upper and
lower tracks. Then, wipe the track clean and lubricate with Lu\
briplateB White
Grease.
Body
Normal use of your vehicle will cause metal-to-metal wear at some points \
on
the cab and body
if they are not lubricated.
tor exposed surfaces, such as door checks, door lock bolts, lock s\
triker
plates, dovetail bumper wedges, etc., a thin film
of engine oil should be
applied.
Where oil holes are provided in the body or cab, a dripless \
oil can be used.
The seat adjusters and seat track should be lubricated with chassis grease.
Door weatherstrips and rubber hood bumpers should be lightly coated with
a
rubber lubricant.
Never use
too much of any lubricant and be sure to wipe up any extra
lubricant when you are finished.
Some parts that need lubricating are hard
to get at. Window regulators and
controls are inside the doors. You can get to these by removing the trim
panels.

Downloaded from www.Manualslib.com manuals search engine The Maintenance Schedule will tell you how often to lubricate these items.
See “Recommended Fluids and Lubricants” in the Index for the proper
lubricant to use.
Lock Cylinders
To be sure your locks operate properly, they must be lubricated. \
The
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 th\
e 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.
Exhaust System
To help prevent damage to your exhaust system, do not continue to drive
your vehicle
if you notice:
Engine misfiring
Loss of performance
Other unusual operating conditions
Have your engine and exhaust system serviced regularly.
Three- Way Catalytic Converter
Your vehicle’s three-way catalytic converter is designed to reduce the
pollutants in your vehicle’s exhaust. Use only unleaded fuel in your vehicle.
If
you use leaded fuel, you could damage your three-way catalytic \
converter,
and other emission control components.
Malfunction Indicator Lamp (SERVICE ENGINE SOON light)
The Malfunction Indicator Lamp (SERVICE ENGINE SOONlight) on y\
our instrument panel lets you know when your emission system needs \
service.
The light will come on briefly when you start your engine to let you know
that the system is working.
If it does not come on when you start your
engine, or
if it comes on and stays on while you’re driving, your system \
may
need service. Your vehicle should still be driveable, but you should have your
system serviced right away.

Downloaded from www.Manualslib.com manuals search engine Your vehicle has a “basecoat/clearcoat” finish. The clearcoat gi\
ves more
depth and gloss to the colored basecoat.
NU I ILt
- -
Machine compounding or aggressive polishing on a basecoatklearcoat
paint finish may dull the finish
or leave swirl marks.
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep their l\
uster. Washing
with water is all that is usually needed. However, you may use
GM Chrome
Polish on chrome
or stainless steel trim, if necessary.
Use special care with aluminum trim. To avoid damaging protective trim, never
use auto
or chrome polish, steam or caustic soap to clean aluminum. A
coating of wax, rubbed to a high polish, is recommended for all bright metal
parts.
Aluminum Wheels (If So Equipped)
Your aluminum wheels have a protective coating similar to the \
painted surface
of your vehicle. Don’t use strong soaps, chemicals, chrome p\
olish,
or other
abrasive cleaners on them because you could damage this coating\
. After
rinsing thoroughly, a wax may be applied.
NOTICE
Weatherstrips
These are places where glass or metal meets rubber. Silicone grease there
will make them last longer, seal better, and not stick
or squeak. Apply silicone
grease with a clean cloth at least every six months.
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal repair or replacement,
make sure the body repair shop applies anti-corrosion material \
to the parts
repaired
or replaced to restore corrosion protection.
Foreign Material
Calcium chloride and other salts, ice melting agents, road oil \
and tar, tree
sap, bird droppings, chemicals from industrial chimneys, and oth\
er foreign matter can damage your vehicle’s finish
if they remain on painted surfaces.
Use cleaners that are marked safe for painted surfaces for the\
se stains.
