(Except All-Wheel Drive)
Tow Limits -- 35 mp11 (56 krnh), 50 rniles (80 km)
NOTICE:
Do not tow with sling-type equipment or the
front bumper system will be damaged. Use
wheel-lift or car-carrier equipment. Additional
ramping
may be required for car-carrier
equipment. Use safety chains and wheel straps.
Towing
a vehicle over rough surfaces could
damage a vehicle. Damage can occur from
vehicle to ground or vehicle to wheel-lift
equipment. To help avoid damage, install
a
towing dolly and raise the vehicle until adequate
clearance
is obtained between the ground and/or
wheel-lift equipment.
Do not attach winch cables or J-hooks to
suspension components when using car-carrier
equipment. Always use T-hooks inserted in
the T-hook slots.

Towing From the Front (All-Wheel Drive)
A towing dolly must be used under the rear wheels when
towing front the front.
NOTICE:
Do not tow with sling-type equipment or the
front bumper system will be damaged. Use
wheel-lift or car-carrier equipment. Additional
ramping may be required
for car-carrier
equipment. Use safety chains and wheel straps.

Engine Overheating
You will find a temperature gage on your vehicle’s
instrument panel.
If Steam Is Coming From Your Engine
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
opening 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.
I 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.
5-13

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:
0 Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer. See “Driving on Grades” in
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.
the Index.
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
-- DRIVE (D).
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, push the accelerator until
the engine speed is about twice as fast as normal idle
speed. Bring the engine speed 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 ofthe
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.
5-14

When you decide it’s safe to lift the hood, here’s what
you’ll see: If the coolant inside the coolant recovery tank is boiling,
don’t do anything else
until it cools down.
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Engine Fan The
coolant level should be at
the ADD mark. 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.
5-15

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.
Engine damage from running your engine without coolant isn’t covered by your warranty.
If there seems to be
no leak, start the engine again. See
if the fan speed increases when idle speed
is doubled by
pushing the accelerator pedal down.
If it doesn’t, your
vehicle needs service. Turn off the 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 the
ADD mark, add a 50/50 mixture of clean
water (preferably distilled) and DEX-COOL TM
(orange-colored, silicate-free) antifreeze at the coolant
recovery tank. (See “Engine Coolant’’
in the Index for
more information.)
Adding only plain water to your cooling system
can be dangerous. 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
50/50 mix of clean
water and
DEX-COOL TM antifreeze.
5-16

NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts. Use the recommended coolant and the proper
coolant mix.
I A 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 tank is at the
ADD mark, start your vehicle.
If the overheat warning continues, there’s one more
thing
you can try. You can add the proper coolant mix
directly
to the radiator, but be sure the cooling system is
cool before you do
it.

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 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.
