upper limits. Don’t drive very long with the tachometer in the yellow range.
If you have a manual transmission, shift to a higher gear as soon as possible.
If you have an automatic transmission, lift your foot off
of the accelerator

Warning Lightsy Gages and Indicators
This section describes the warning lights and gages that may be on your
vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something is wrong be\
fore it
becomes serious enough to cause an expensive repair or replacem\
ent.
Paying attention to your warning lights and gages could also s\
ave you or
others from injury.
Warning lights
go on when there may be or is a problem with one of your
vehicle’s functions.
As you will see in the details on the next few pages,
some warning lights come on briefly when you turn the ignition\
key just to
let you know they’re working. If you are familiar with this sec\
tion, you
should not
be alarmed when this happens.
Gages can indicate when there may be or is a problem with one
of your
vehicle’s functions. Often gages and warning lights work toge\
ther to let you
know when there’s a problem with your vehicle.
When one of the warning lights comes on and stays on when you are
driving, or when one of the gages shows there may be a problem, check the
section that tells you what to
do about it. Please follow the manual’s advice.
Waiting to do repairs can be costly
- and even dangerous. So please get to
know your warning lights and gages. They’re a big help.

Downloaded from www.Manualslib.com manuals search engine Driving On Grades
Reduce speed and shift to a lower gear before you start dawn a long or
steep downgrade. If you don’t shift down, you might have to use your
brakes
so much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your speed
to around 45 mph
(70 km/h) to reduce the possibility of engine and transmission overheating.
If you have an automatic transmission, you should use “D” when towing a
trailer. Operating your vehicle
in “D” when towing a trailer will minimize
heat buildup and extend the life of your transmission.
Or, if you have a
rrianual transmission with fifth gear, it’s better not to use fifth gear, just
drive in fourth gear (or, as
you need to, a lower gear).
Parking on Hills
You really should not park your vehicle, with a trailer attached, \
on a hill. If
something goes wrong, your rig could start to move. People
can be injured,
and both your vehicle and the trailer can be damaged.
But if you ever have
to park your rig on a hill, here’s how to do it:
1. Apply your regular brakes, but don’t shift into “P” (Park) yet, or into

in a drive gear-not in “N” (Neutral).

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 store 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, belt, cooling system, an\
d brake
adjustment. 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.

Jump Starting
If your battery has run down, you may want to use another ve\
hicle and some
jumper cables to
start your vehicle. But please follow the steps below to do
it safely.
NOTICE:
Ignoring these steps could result in costly damage to your
vehicle that wouldn’t be covered by your warranty.
Trying to start your vehicle by pushing or pulling

To Jump Start Your Vehicle:
1. Check the other vehicle. It must have a 12-volt battery wlm a\
negauve
ground system.
NOTICE:
If the other system isn’t a 12-volt system with a negative \
ground, both vehicles can be damaged.
2. Get the vehicles close enough so the jumper cables can reach, but be
sure the vehicles aren’t touching each other. If they are, it could cause
a
ground connection you don’t want. You wouldn’t be able to start your
vehicle, and the bad grounding could damage the electrical syst\
ems.
You could be injured if the vehicles roll, Set the parking brake
firmly
on each vehicle. Put an automatic transmission in “P” (Park)\
or a
manual transmission
in “N’ (Neutral). If you have a four-wheel drive
vehicle with
a manual transfer case shift lever, be sure the transfer case
is not in “N’ (Neutral).
3. Turn off the ignition on both vehicles. Turn off all lights t\
hat aren’t
needed, and radios. This will avoid sparks and help save both batteries.
And it could save your radio!

If you leave your radio on, it could be badly damaged. The
repairs wouldn’t be covered by your warranty.
4. Open the hoods and locate the batteries. Find the positive (+) and
negative
(-) terminals on each battery.
