Attach the cable at least 18 inches (45 cm) away
from the dead battery, but not near engine parts that
move. The elactrical connection
is just as goad
there, but the chance of sparks gettmg back to the
battery is much less.
Now start the vehicle with the good battery
and run
the engine for a while.
Try to start the vehicle with the dead battery.
If it won’t start after a few tries, it probably
needs service.
13. Remove the cables in reverse order to prevent
electrical shorting. Take care that they don’t touch
each other
or any other metal.

Engine Overheating
You will find a coolant temperab Ire gage on
vehicle’s instrument panel. see “Engine Coo

your

in the Index. You will also find a
low coolant level waming light on your vehicle’s
instrument panel. See
“LOW Coolant Warning Light”
in the Index.

Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn it off and get everyone away
from the vehicle until it cools down. Wait until
there is no sign of steam or coolant before you
open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine
if
it overheats, and get out of the vehicle until the
engine is cool.
~~ ~
NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.

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.
a 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. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (D) or
THIRD
(3).
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for about
10 minutes. If the warning doesn’t come 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, you can idle the engine
for
two or three minutes while you’re parked, to 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.

Cooling System
When you decide it’s safe to lift the hood, here’s what
you’ll see:
A Coolant Surge Tank with Pressure Cap
B. Electric Engine Cooling Fans

Ik I
/!II CAUTION:
An electric engine cooling fan under the hood can
start up even when the engine is not runnimg
and
can injure you. Keep hands, clothing and tools
away from any underhood electric fan.
If the coolant inside the coolant surge tank is boiling,
don’t
do anytlung else until it cools down.
Page 202 of 348
The coalant level should be at or above FULL COLD
m-ark .or slightly higher.
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water
pump or somewhere else in
the cooling system.
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine
if there is a leak. If you run
the engine, it could lose all coolant. That could
cause
an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
1 NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fans are running.
If the
engine is overheating, both fans should be running.
If
they aren’t, your vehicle needs service.

How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
FULL COLD mark or slightly higher, add a
50/50 mixture of clean water (preferably distilled) and
DEX-COOL’ coolant at the coolant surge tank, but be
sure the cooling system, including the coolant surge tank
pressure cap,
is cool before you do it. (See “Engine
Coolant’’ in the Index for more infomation.)
I
Steam and scaldmg liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and
if you turn the coolant
surge tank pressure cap
-- even a little -- they
can come out at high speed. Never
turn the cap
when the cooling system, including the coolant
surge tank pressure cap, is hot. Wait for the
cooling system and coolant surge
tank pressure
cap to cool
if you ever have to turn the
pressure cap.

I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
You can be bmrned 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.
1. You can remove the coolant mge tank pressure .cap
when the cooling system, inclu-ding the coalimt surge
tank pressare cap and upper radiatox hose, is no
longer hot. Tm the pressure cap slowly about
one-quafter
turn to the left and then stop.
If you hear a hiss, wait for that to stop. A hiss means
there is still some pressure left.

If a Tire Goes Flat
It’s unusual
for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly. If air goes
out
of a tire, it’s much more likely to leak out slowly.
But if you should ever have a “blowout,” here
are a few
tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that\
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a
skid.
In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to
go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to
a level place. Turn on your hazard
warning flashers.
:, , ,::*,,
Changing a tire can cause an injury. The vehicle
can slip off the jack and roll over you or other
people. You and they could be badly injured.
Find
a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. ’krn off the .engine.
To be even more certain the vehicle won’t move,
you can put blocks
at the front and rear of the
tire farthest away from the one being changed.
That would be the’ tire on the other side of the
vehicle, at the opposite end.

Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire or wheel with
other wheels or tires. They won’t fit. Keep your spare
tire
and its wheel together.
NOTICE:
Tire chains won’t fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don’t use tire chains on your
compact spare.
If You’re Stuck: ,In Sand, Mud,
Ice or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known as
“rocking” can help you get out when you’re stuck, but \
you must use caution.
A CAUTION:
If you let your tires spin at high speed, they can
explode, and you or others could be injured. And,
the transaxle or other parts
of the vehicle can
overheat. That could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels as little
as possible. Don’t
spin the wheels above
35 mph (55 km/h) as shown
on the speedometer.
