Engine Coolant Heater (Option)
In very cold weather, 0
F (-18
C) or colder, the engine
coolant heater can help. You'll get easier starting and
better fuel economy during engine warm
-up. Usually,
the coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is attached to the underside of the diagonal
brace, which is located above the engine air
cleaner/filter assembly.
3. Plug it into a normal, grounded 110
-volt AC outlet.
CAUTION:
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
11 0
-volt AC outlet. If the cord won't reach, use a
heavy
-duty three-prong extension cord rated for
at least 15 amps.

2-34
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it away
from moving engine parts. If you don't, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.Automatic Transaxle Operation
Console Shift Lever
Your automatic transaxle may have a shift lever on the
steering column or on the console between the seats.

Engine Coolant Temperature Gage
United States-3400 V6
Engine ClusterUnited States-3800 V6
Engine Cluster
Canada-3400 V6
Engine ClusterCanada-3800 V6
Engine ClusterThis gage shows the engine coolant temperature.
It also provides an indicator of how hard your vehicle is
working. During the majority of the operation, the gage
will read 210
F (100
C) or less.
If you are pulling a load or going up hills, it is normal
for the temperature to fluctuate and approach the 250
F
(122
C) mark. When the gage reads greater than 250
F
(122
C), the HOT COOLANT TEMP light will be
illuminated in the message center and a chime will
sound continuously. If the gage reaches the 260
F
(125
C) mark, it indicates that the cooling system is
working beyond its capacity.
See ªEngine Overheatingº in the Index.

Battery Life Indicator
When the vehicle is started
this message will be
displayed for three seconds.
If the message is displayed when the engine is running,
you may have a problem with your charging system. If
there is a problem with the charging system, four chimes
will sound when the message comes on. The battery
display will also stay on while the key is in ON until the
engine is started.
If the message stays on after starting the engine it
could indicate a problem with the generator drive belt,
or some other charging system problem. Have it
checked right away. Driving with this message on
could drain your battery.
If you must drive a short distance with this message
displayed, it helps to turn off all your accessories.Hot Coolant Temp
United States Canada
This message is displayed when the cooling system
temperature gets hot. A chime will sound
continuously, also.
Check the coolant temperature gage and the coolant
level. See ªEngine Coolant,º ªEngine Coolant
Temperature Gageº and ªEngine Overheatingº in the
Index for further information.

2-91
Low Coolant Level
United States Canada
This message is displayed when the cooling system is
low on coolant. Four chimes will also sound.
The engine may overheat. See ªEngine Coolantº in the
Index and have your vehicle serviced as soon as you can.Low Oil PressureUnited States Canada
This message is displayed when the engine oil
pressure is low. A chime will sound continuously, also.
See ªLow Oil Pressure Lightº earlier in this section.

Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See ªRoadside
Assistanceº and ªRecreational Vehicle Towingº in
the Index.
Engine Overheating
You will find a coolant temperature gage and a warning
light about a hot engine on your instrument panel
cluster. See ªEngine Coolant Temperature Gageº and
ªHot Coolant Temperature Messageº in the Index.
You also have a low coolant light on your instrument
panel cluster. See ªLow Coolant Level Messageº in
the Index.
Overheated Engine Protection
Operating Mode
This emergency operating mode allows your vehicle
to be driven to a safe place in an emergency situation.
Should an overheated engine condition exist, an
overheat protection mode which alternates firing groups
of cylinders helps prevent engine damage. In this mode,
you will notice a significant loss in power and engine
performance. The low coolant light may come on and
the temperature gage will indicate an overheat condition
exists. Towing a trailer in the overheat protection mode
should be avoided.
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss and change the oil.
See ªEngine Oilº in the Index.
