The oil pressure gage shows the engine oil pressure in psi (\
pounds per square inch) when the engine
is running. Canadian vehicles indicate pressure
in kPa (kilopascals). Oil pressure may vary with engine speed\
, outside
temperature and
oil viscosity, but readings above the low pressure zone
indicate the normal operating range.
2-78

A reading in the low pressure zone may be caused by a dangerouslv low oil
level or other problem causing low oil pressure. Check your oi\
l as soon as
possible.
CAUTION
Don’t keep driving if the oil pressure is low. If you do, your engine
can become so hot that it catches on fire, You or others could be
burned. Check your oil as soon as possible and have your vehicle
serviced.

When your engine is not running, but the ignition is on (in \
the Run position),
this gage
shows your battery’s state of charge in DC volts. When the engine
is running, the gage shows the condition
of the charging system. Readings
between the low and high warning zones indicate the normal ope\
rating range.
Readings in either warning zone indicate a possible problem in \
the electrical
system.

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.

. .
6. Release the regular brakes.
CAUTION
It can be dangerous to get out of your vehicle if the shift lever is no
fully in
P (Park) wi-. the parking brake firmly set. Your vehicle can
roll.
If you have left the engine running, the vehicle can move suddenl\
y.
You or others could be injured.
To be sure your vehicle won’t move,
when you’re on fairly level ground, use the steps that foll\
ow.
If you have four-wheel drive and your transfer case is in N (Neutral),
your vehicle will be free to
roll, even if your shift lever is in P (Park)
So, be sure the transfer case is in a drive gear-not in N (Neutral).
If you are parking on a hill, or if you’re pulling a trailer, also see
I “Parking On Hills” in the Index. I
When You Are Ready to Leave After Parking on a Hill
1. Apply your regular brakes and hold the pedal down while you:
Start your engine.
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and stow the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re pulling a \
trailer. .See
the Maintenance Schedule for more on this. Things that are especially
important in trailer operation are automatic transmission fluid (don’t overfill),
engine oil, axle lubricant, belts, cooling system, and brake ad\
justment. Each
of these is covered in this manual, and the Index will help you find them
quickly.
If you’re trailering, it’s a good idea to review these sections before
you start your trip.
Check periodically to see that all hitch nuts and bolts are tight.

An electric fan under the hood can start up even when the engine is
not running and can injure you. Keep hands, clothing, and tools
away from any underhood
electric fan.
CAUTION
If the coolant inside the coolant recovery tank or surge tank is \
boiling, don't
do anything else until it cools down.

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.

CAUTION

You can be burned if you spill coolant on hot engine parts. Coolant
contains ethylene glycol
and it will burn if the engine parts are hot
enough. Don’t spill coolant on
a hot engine.
When the coolant in the coolant recovery
is at or above COLD, start your
vehicle.

Fuels in Foreign Countries
If you plan on driving in another country outside the US. or Canada,
unleaded fuel may be hard
to find. Do not use leaded gasoline. If you use
even one tank full, your emission controls won’t work well \
or at all. With
continuous use, spark plugs can get fouled, the exhaust system \
can corrode,
and your engine
oil can deteriorate quickly. Your vehicle’s three-way catalytic
converter and oxygen sensor will be damaged.
All of that means costly
repairs that wouldn’t
be covered by your warranty.
To check on fuel availability, ask an auto club, or contact a major oil
company
that does business in the country where you’ll be driving.
You can also write us at the following address for advice. Just tell us where
you’re
going and give your Vehicle Identification Number (VIN).

~AUTION
- Things that burn can get on hot engine parts and start a fire. These
include liquids like gasoline,
oil, coolant, brake fluid, windshield
washer and other fluids, and plastic or rubber.
You or others could
be burned. Be careful not to drop or spill things that will burn onto a
Before closing the hood, be sure
all the filler caps are on properly. Then just
pull the
hood down and close it firmly.
Engine Oil
It's a good idea to check your engine oil every time you get fuel. In order to
get an accurate reading, the
oil must be warm and the vehicle must be on
level ground.
Turn
off the engine and give the oil a few minutes to get back down into the
oil pan. If you don't, the oil dipstick might not show the actual level.
