Cruise Control (Option)
With Cruise Control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot on
~ the accelerator. This can really help on long trips. Cruise
Control
does not work at speeds below about 25 mph
(40 km/h).
When you apply your brakes, the Cruise Control shuts
off.

/I CAUTION:
If you let your tires spin at high speed when the
“TRACTION OFF“ warning light is on, they can
explode and you or others could be injured. And,
spinning your tires with the “TRACTION OFF”
warning light on can cause the transaxle to
overheat
or can cause other problems. That
could
cause an engine 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/hl as shown on the speedometer.
I
:’NOTICE:
Spinning your wheels whel. ..?e “Tl .A (ION
OFF” warning light is on can destroy parts 01
your vehicle as well as the tires. If you spin your
wheels too fast while shifting your transaxle
back and forth, you can destroy your transaxle.

Engine Coolant
Temperature Warning
Light
TEMP
This light tells you that your engine coolant has
overheated or your radiator cooling fans are
not
working. If you have been operating your vehicle under
normal driving conditions, you should
pull off the road,
stop your vehicle and turn the engine
off as soon as
possible.
HOT COOLANT CAN BURN YOU BADLY!
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating”
in the Index.

Front Towing Hook-Ups Position a 4” x 4” wood beam across the sling chains
contacting the bottom
of the radiator support. Position
the lower sling crossbar just under
the front bumper.
Attach a separate safety chain around the outboard
end
of each lower control arm.
Attach
“T” hook
chains behind the front wheels into the
bottom slots
of the cradle rails on both sides.
I

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 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.

When you decide it's safe to lift the hood, here's what
you'll

If the coolant inside the coolant recovery tank is boiling,
don't do anything else until it cools down.

P
The coolant level should be at or above "FULL COLD.''
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,
I
/A CAUTION: 0
Heater and radiator hoses, and other engine
parts, can be very
hot. Don't touch them. If you p
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.
I
Engine damage from running your engine
without coolant isn't covered by your warranty.
If there seems to be no leak, check to see if the electric
engine 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
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at or above
“FULL COLD,” add a 50/50 mixture of
clean water (preferably distilled) and
a proper
antifreeze at the coolant recovery tank. (See “Engine
Coolant”
in the Index for more information about the
proper coolant mix.)
‘A CAUTION: Q
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 vbhicle’s coolant warning
system
is set for the properecoolant mix. With
plain water or the’wrong mix, your engine could
get too hot
but you douldn’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
a proper antifreeze.”

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 or
above “FULL COLD,” 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 radiatorpressure
cap, is hot. Wait for the cooling system and
radiator pressure
cap to cool if you ever have40
turn the pressure cap.
