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 your vehicle’s
dealerships all across North America. They’ll be ready and w\
illing to help
if
you need it.
Here are some things you can check before a trip:
e
e
On
Windshield Washer Fluid: Is the reservoir full? Are all windows clean
inside and outside?
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?
Weather Forecasts: What’s the weather outlook along your route?
Should you delay your trip a short time to avoid a major storm system?
Maps: Do you have up-to-date maps?
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 s\
ome refreshment
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.
On two-lane highways or undivided multilane highways that do not have
controlled access, you’ll want to watch for some situations not usually found
on freeways. Examples are: stop signs and signals, shopping cen\
ters with
direct access to the highway, no passing zones and school zones, vehicles
turning left and right
off the road, pedestrians, cyclists, parked vehicles, and
even animals.

antifreeze at the coolant recovery tank. (See “Coolant” i\
n the Index for more information about the proper coolant mix.)
Adding only plain water to your cooling system can be dangerou\
s. 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, your
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
a 50150 mix of clean water and a proper antifreeze. I I
NOTICE I
In cold weather, water can freeze and crack the engine. radiator, heater
I core and other parts. Use the recommended coolant.

J
PO232
To replace the windshield wiper blade insert, lift the wiper arm and rotate the
blade until
it is facing away from the windshield. Unlatch the end of the insert
from the holding clips. Remove the insert and slide a new one in place,
Make sure the blade
is secured in the clips.
Air Conditioning
Every now and then have your dealership check your air conditioning system
to be sure it has not lost any cooling ability,
If you think the system is not
working properly, have your dealership check
it out as soon as possible.
The air conditioning will not work when the temperature is below
40°F (4°C).
Fluid Leak Check
After the vehicle has been parked for a while, inspect the su\
rface under the
vehicle for water, oil, fuel or other fluids. Water dripping from the air
conditioning system after
it has been used is normal. If you notice fuel leaks
or fumes, the causes should be found and corrected at once.
Lubrication
Accelerator Control System
Your maintenance schedule will tell you how often the accelerator linkage
pivot points must be lubricated. See “Recommended Fluids and Lubric\
ants”
in
the Index for the proper lubricant to use.
Accelerator cables and cruise control cables should not be lubr\
icated. Any
cables that are worn or are hard to pull
should be replaced.

Hood Laiches and Hood Hinge
Your maintenance schedule will tell you how often to lubricate the hood latch
and hood hinge assembly. See “Recommended Fluids and Lubrican\
ts” in the
Index for the proper lubricant to use.
Propeller Shaft Slip Splines
See your maintenance schedule to find out 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
See your maintenance schedule to find out how often the consta\
nt velocity
joints must be lubricated. See “Recommended Fluids and Lubricants”\

in the
Index for the proper lubricant to use.
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.
For exposed surfaces, such as door checks, door lock bolts, lo\
ck striker
plates, dovetail bumper wedges, etc., a thin film of engine oil should be
applied.
The seat adjusters and seat track should be lubricated with ch\
assis grease, Door weather strips and rubber hood bumpers should be lightly \
coated with a
rubber lubricant.

for the proper
lubricant to use.
Lock Cylinders

“Recommended Fluids and Lubricants”
in the Index for the proper lubricant to
use.
You should not use penetrating oils because they could wash out the 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.

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 polis\
h, or other
abrasive cleaners on them because you could damage this coating\
. After
rinsing thoroughly, a wax may be apptied.
NOTICE 1
f you have aluminum wheels, don’t use an automatic vehicle wash that
?as hard silicon carbide cleaning brushes. These brushes can take
off the
xotective coating.
White Sidewall Tires
Your General Motors dealer has a GM White Sidewall Tire Cleaner. You can
use a stiff brush with
it.
Weatherstrips
These are places where glass or metal meets rubber. Silicone g\
rease there
will make them last longer, seal better, and not stick or squeak. Apply silic\
one
grease with a clean cloth at least eve@ 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 0the.r 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.
Finish Damage
Any stone chips, fractures or deep scratches in the finish should be repaired
right away. Bare metal will corrode quickty and may develop into a major
repair expense.
