Engine Coolant Heater
Your vehicle may be equipped with an engine coolant
heater.
A. Engine Oil Dipstick Location
B. Engine Coolant Heater Cord
C. Transaxle Dipstick/Fluid Fill LocationIn very cold weather, 0°F (−18°C) or colder, the engine
coolant heater can help. You will 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. At
temperatures above 32°F (0°C), use of the coolant
heater is not required.
2-27

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is located on the driver’s side
of the engine, behind the transaxle dipstick/uid ll
location (C) and next to the engine.
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 re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
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 do not, 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 will be parking
your vehicle. The dealer can give you the best advice
for that particular area.
Automatic Transaxle Operation
The automatic transaxle may have a shift lever located
either on the steering column or on the console
between the seats.
There are several different
positions for the shift lever.

Engine Coolant Temperature
Warning Light
This light tells you that
your engine has
overheated. As a check,
the light should come
on for a few seconds when
you start your engine.
If this light comes on and stays on, you should stop your
vehicle and turn the engine off as soon as possible. A
warning chime should also sound if this light comes on.
SeeEngine Overheating on page 5-31.
Engine Coolant Temperature Gage

This gage shows the
engine coolant
temperature. If the gage
pointer moves into
the shaded area, the
engine is too hot.
That reading means the same thing as the warning
light – the engine coolant has overheated. SeeEngine
Overheating on page 5-31.Malfunction Indicator Lamp

BATTERY VOLTAGE LOW – 6:This message will
appear when the electrical system is charging less than
10 volts or if the battery has been drained. If this
message appears immediately after starting, it is
possible that the generator can still recharge the battery.
The battery should recharge while driving but may
take a few hours to do so. Consider using an auxiliary
charger (be sure to follow the manufacturer’s
instructions) to boost the battery after returning home or
to a nal destination. If this message appears while
driving or after starting your vehicle and stays on, have
it checked immediately to determine the cause of
this problem. To help the generator recharge the battery
quickly, you can reduce the load on the electrical
system by turning off the accessories. You can monitor
battery voltage on the DIC by pressing the INFO
button. The normal range is 11.5 to 15.5 volts.
CHANGE ENGINE OIL – 82:This means that the life
of the engine oil has expired. SeeScheduled
Maintenance on page 6-4. After an oil change, the Oil
Life Indicator must be reset. SeeOil Life Indicator
on page 3-89. SeeEngine Oil on page 5-15.CHANGE TRANS FLUID – 47:This message will
appear when it is time to change the transaxle uid. See
Scheduled Maintenance on page 6-4for the proper
uid and change intervals.
CHECK BRAKE FLUID – 37:This message will display
if the ignition is in ON to inform the driver that the brake
uid level is low. Have the brake system serviced by a
technician as soon as possible. SeeBrake System
Warning and Parking Brake Indicator Light on page 3-51.
CHECK COOLANT LEVEL – 2:This message will
appear when there is a low level of engine coolant. Have
the cooling system serviced by a technician as soon
as possible. SeeEngine Coolant on page 5-27.
CHECK FUEL GAGE – 50:(Analog Cluster) This
message will appear when the fuel supply is less than
5 gallons (18.9 L) and the display is turned off. A
single chime will also sound when this message is
displayed.
CHECK GAS CAP – 61:This message will appear if
the gas cap has not been fully tightened. You should
recheck your gas cap to ensure that it is on properly.
3-66

DRIVE NO. X (1 OR 2):This message will be displayed
with the key in ON and while entering FEATURE
PROGRAMMING, but only if the vehicle is equipped
with memory seats. The message will show which driver
is activating the personalization feature. It will only
stay on for ve seconds. This message can be
customized for you by your dealer.
ENGINE COOLANT HOT, IDLE ENGINE – 44:This
message will appear when the engine coolant
temperature is over 262°F (128°C). Stop and allow your
vehicle to idle in PARK (P) until it cools down and the
message is removed. Do not increase engine speed
above a normal idle. If it does not cool down, turn off the
engine and have it serviced before driving it again.
Severe engine damage can result from an overheated
engine. SeeEngine Overheating on page 5-31.
ENGINE HOT–AC OFF – 16:This message displays
when the engine coolant becomes hotter than the normal
operating temperature. To avoid added strain on a hot
engine, the air conditioning compressor is automatically
turned off. When the coolant temperature returns to
normal, the A/C operation will automatically resume. You
can continue to drive your vehicle. If this message
continues to appear, have the system repaired as soon
as possible to avoid compressor damage.ENGINE OVERHEATED, STOP ENGINE – 42:This
message will appear when the engine has overheated.
Stop and turn the engine off immediately to avoid
severe engine damage. SeeEngine Overheating on
page 5-31. A multiple chime will also sound when this
message is displayed.
ENGINE POWER REDUCED – 41:This message
informs you that the vehicle is reducing engine power
because the transaxle is being placed in gear under
conditions that may cause damage to the vehicle’s
engine, transaxle or ability to accelerate.
FUEL LEVEL LOW – 11:This message serves as a
warning that the fuel level in the tank is critically
low. Stop for fuel soon. A single chime will sound when
this message is displayed.
HEADLAMPS SUGGESTED – 23:If it is dark enough
outside and the headlamps and Twilight Sentinel
®
controls are off, this message will display on the DIC.
This message informs the driver that turning on the
exterior lamps is recommended even though the DRL
are still illuminated. It has become dark enough outside
to require the headlamps and/or other exterior lamps.
This message will also appear if the optional
Rainsense™ wiping feature is on and the Twilight
Sentinel
®is off.
