In very cold weather, 0°F (-18°C) or colder, the optional engine block heater
can help. You’ll get easier starting and better fuel economy\
during engine
warm-up.
To use the brock heater:
1. Turn
off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 1 IO-volt outlet.
A
Plugging the cord into an ungrounded outlet could cause an electrical
shock.
Also, the wrong kind of extension cord could overheat and
cause a fire. You could be seriously injured. Plug the cord into a
properly grounded three-prong 110-volt outlet.
If the cord won’t reach,
use a heavy-duty three-prong extension cord rated for at least \
15
amps.

Leaving Your Vehicle With the Engine Running
(Automatic Transmission Models Only)
1 CAUTION
It can be dangerous to leave your vehicle with the engine running.
Your vehicle could move suddenly
if the shift lever is not fully in P
(Park) with the parking brake firmly set. If you have four-wheel drive
with a manual transfer case shift lever 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). And, if you leave the vehicle with the engine running, it
could overheat and even catch fire. You or others could be injured.
I Don’t leave your vehicle with the engine running unless you have to.
If you have to leave your vehicle with the engine running, be sure your
vehicle is in
P (Park) and your parking brake is firmly set before you leave it.
If you have four-wheel drive with a manual transfer case shift le\
ver, be sure
that the transfer case is in
a drive gear-not in N (Neutral). After you’ve
moved the shift lever into the
P (Park) position, hold the regular brake pedal
down. Then, see if you can move the shift lever away from P (Park) without
first pulling it toward you.
If you can, it means that the shift lever wasn’t fully
locked into
P (Park).
Parking Your b bide (Manual Transmission Models
Before you get out of your vehicle, put your manual transmissi\
on in R
(Reverse) and firmly apply the parking brake.
If you have four-wheel drive with a manual transfer case shift le\
ver, be sure
your transfer case is in a drive gear. Your vehicle could roll
if it isn’t.

Downloaded from www.Manualslib.com manuals search engine Most drivers treat their brakes with care. Some, however, overw\
ork the
braking system with poor driving habits.
Avoid needless heavy braking. Some people drive in spurts-heavy
acceleration followed by heavy braking-rather than keeping pace with
traffic. This is a mistake. Your brakes may not have time
to cool
between hard stops. Your brakes will wear out much faster
if you do a
lot of heavy braking.
Don’t “ride” the brakes by letting your left foot rest lightly on the brake
pedal while driving.
I
“Riding” your brakes can cause them to overheat to the point that
they won’t work well. You might not be able to stop your vehicle in
time
to avoid an accident. If you “ride” your brakes, they will get so
hot they will require a lot of pedal force to slow you down. Avoid
“riding” the brakes.

Downloaded from www.Manualslib.com manuals search engine Your Driving and the Road
If you decide you can go down a hill safely, then try to keep \
your vehicle
headed straight down, and use a low gear. This way, engine drag can help
your brakes and they won’t have to do all the work. Descend slowly, keeping
your vehicle under control at all times.
A
Heavy braking when going down a hill can cause your brakes to
overheat and fade. This could cause
loss of control and a serious
accident. Apply the brakes lightly when descending a hill and use a
low gear to keep vehicle speed under
1 control.
Q: Are there some things I should not do when driving down a hill?
A: Yes! These are important because
if you ignore them you could lose
control and have a serious accident.
When driving downhill, avoid turns that take you across the in\
cline of the
hill. A hill that’s not too steep to drive down may be too steep to drive
across. You could roll over
if you don’t drive straight down.
Never go downhill with the transmission in N (Neutral), or with the clutch
pedal depressed in a manual shift. This is called “free-wheeling.” Your
brakes will have to do all the work and could overheat and fade.
Avoid braking so hard that you lock the wheels when going downhill. If
your front wheels are locked, you can’t steer your vehicle. \
If your wheels
lock up during downhill braking, you may feel the vehicle starting to slide
sideways.
To regain your direction, just ease off the brakes and steer to
keep the front of the vehicle pointing straight downhill.
Q: Am I likely to stall when going downhill?
A: It’s much more likely to happen going uphill. But if it happens going
downhill, here’s what to do.
* Stop your vehicle by applying the regular brakes. Apply the parking
brake.
Shift to P (Park) (or to N (Neutral) with the manual transmission) and,
while still braking, restart the engine.
Shift back to a low gear, release the parking brake, and drive straight
down.

If No Steam Is Coming From Your Engine:
If you get the overheat warning but see or hear no steam, the problem may
not be too serious. Sometimes the engine can get a little
too hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam, try this for a minute
or so:
1. If you have an air conditioner, turn it off.
2. Turn your heater to full hot at the highest fan speed and open the

window as necessary.
If you no longer have the overheat warning, you can drive. Just to
be safe,
drive slower for about ten minutes. If the warning doesn't com\
e back on, you
can drive normally.
If the warning continues, pull over, stop, and park your vehicle \
right away.
If there's still no sign of steam, push the accelerator until the engine speed is
about twice as fast as normal idle speed. Bring the engine sp\
eed back to
normal idle speed after
two or three minutes. Now see if the warning stops.
But then,
if you still have the warning, TURN OFF THE ENGINE AND GET
EVERYONE
OUT OF THE VEHICLE until it cools down.
You may decide
not to lift the hood but to get service help right away.

Downloaded from www.Manualslib.com manuals search engine How to Add Coolant to the Coolant Recovery Tank
If you haven’t found a problem yet, but the coolant level isn’t at or above the
ADD mark, add a 50/50 mixture of clean water (preferably distilled) and the
proper antifreeze at the coolant recovery tank. (See “Engine\
Coolant” in the Index for more information about the proper coolant mix.)
I CAUTION
4
Adding only plain water to your cooling system can be dangerous.
Rain water,
or some other liquid, like alcohill, 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 5Q/M mix of clean wafer and a proper antifreeze.
NOTICE
In cold weather, water can freeze and crack the en1
core and other
parts. Use the recommended coolan
*
I CAUTION
I I
You can be burned if you spill coolant on hot engine parts. Coolant
b contains ethylene glycol and it wil’l burn if the engine parts are hot
I’ enough. Don’t spill coolant on a hot engine.
When the coolant in the coolant recovery tank is at or above \
the
ADD mark,
start your vehicle.
If the overheat warning continues, there’s one more thing you c\
an try. You
can add the proper coolant mix directly to the radiator, but \
be sure the
cooling system
is cool before you do it.
A
Steam and scalding liquids from a hot cooling system can blow out
and burn you badly. They are under pressure, and if you turn the
radiator pressure cap-even a little-they can come out at high
speed. Never turn the pressure cap when the cooling system, including the radiator pressure cap, is hot. Wait for the cooling
system and radiator pressure cap
to cool if you ever have to turn
the pressure cap.

If You’re Stuck: In Sand, Mud, Ice or

What you don’t want to do when your vehicle is stuck is to spin your
wheels. The method known as “rocking” can help you get o\
ut when you’re
stuck, but you must use caution.
~
fi If you let your tires spin at high speed, they can explode and you1 or
others could be injured. And, the transmiss’ion or other parts of the
vehicle
can overheat. That could cause an engine comparlme’nt fire
or other damage. When you’re
stuck, spin the wheels as little as
possible.
Don’t spin the wheels above 35 rnph 1(55 krn/h) as shown
oln the speedometer.
Rocking Your Vehicle To Get It Out:
First, turn your steering wheel left and right. That will clear the area \
around
your front wheels. Then shift back and forth between
R (Reverse) and a
forward gear (or with a manual transmission, between
1 (First) or 2 (Second)
gear and
R (Reverse), spinning the wheels as little as possible. Release \
the
accelerator pedal while you shift, and press lightly on the accelerator pedal
when the transmission is in gear.
If that doesn’t get you out after a few tries,
you may need to be towed
out. Or, you can use your recovery hooks, if your
vehicle has them.
If you do need to be towed out, see “Towing Your Vehicle’’
in the Index.
