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.

The Certificationflire 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 the GVWR
(Gross Vehicle Weight Rating). The GVWR includes the weight o\
f the vehicle,
all occupants, fuel and cargo.
The Certificationnire 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 Gross Axle Weight Rating
(GAWR) for either the front or rear axle.
And,
if you do have a heavy load, you should spread it out.
A
Do not load your vehicle any heavier than the GVWR or the I
maximum front and rear GAWRs. If you do, parts on your vehicl\
e
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.
Using heavier suspension components
to get added durability might not
change your weight ratings. Ask your dealer to help you load your vehicle the
right way.

nth
or more. Also, check the
tire pressure of the spare tire.
How to Check: Use a good quality pocket-type gage to check tire pressure.
Simply looking at the tires will not tell you the pressure, e\
specially if you
have radial tires-which may look properly inflated even
if they’re
underinflated.
If your tires have valve caps, be sure to put them back on. The\
y help
prevent leaks by keeping out dirt and moisture.
Special Tire Inflation
If you have 16 inch tires on your vehicle, and:
- You’ll be driving for very long at speeds of 66 mph (105 km/h) to 75
mph
(120 km/h) where legal, inflate tires 10 psi (70 kPa) more than
the recommended
cold inflation pressure,
- You’ll be driving for very long at speeds of 76 mph (120 kmih) to 85
mph (135 km/h) where legal, cold inflation pressure should be
increased
by 10 psi (70 kPa) and you must also reduce axle load
capacity by
10%. Do not drive over 85 mph (135 kmlh) even if
it’s legal.
- Inflation pressures should never exceed 10 psi (70 kPa) above the
inflation specified for the maximum
load of the tire.

On manual transmission vehicles, put the shift lever in N (Neutral), push the
clutch down halfway, and try
to start the engine. The starter should work only
when the clutch is pushed down all the way to the floor.
Steering column lock operation -While parked, try to turn the key to Lock
in each gear shift position.
With an automatic transmission, the key should turn to
Lock only when the
gear shift is in
P (Park).
On vehicles with a key release lever,
try to turn the key to Lock without
pressing the lever. The key should turn to
Lock only with the key lever
depressed.
On all vehicles, the key should come out only in
Lock.

When you are doing this check, your vehicle could begin to move.
You
or others could be injured and property could be damaged.
Make sure there
is room in front of your vehicle in case you begin
to roll. Be ready to apply the regular brake at once should the
vehicle begin to move.
Park on a fairly steep hill, with the vehicle facing downhill. Keeping yo\
ur foot
on the regular brake, set the manual parking brake.
CAUTION
To check the parking brake: With the engine running and the
transmission in
N (Neutral), slowly remove foot pressure from the regular
brake pedal.
Do this until the vehicle is held by the parking brake only.
To check the “Park” mechanism’s holding ability: Apply the \
regular brake
and shift to
P (Park). Release the manual parking brake, then slowly
release the regular brake.
Lap and shoulder belts condition and operation -Inspect belt system,
including: webbing, buckles, latch plates, retractors, guide loop\
s and anchors.
Have a belt assembly replaced if the webbing has been cut or otherwise
damaged.
Body Lubrication Service -Lubricate all body door hinges with engine oil.
Also lubricate the tailgate, tailgate handle pivot points, and \
tailgate mounted
spare tire carrier
(if equipped). Lubricate the body hood, fuel door and rear
compartment hinges, latches and locks including interior glove b\
ox and
console doors, and any folding seat hardware. Lubricate the hoo\
d safety lever
pivot and prop rod pivot.
More frequent lubrication may be required when
exposed to a corrosive environment.
