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/fluid fill
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 fire. 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
There are several different
positions for the shift lever,
which is located on the
console between the seats.
PARK (P):This position locks the front wheels. It is the
best position to use when you start the engine
because your vehicle cannot move easily.

•If the traction control system is affected by an
engine-related problem, the system will turn off and
the warning light will come on.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
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 5-26.
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 5-26.

CHANGE ENGINE OIL – 82:This means that the life
of the engine oil has expired and it should be changed
within 200 miles. After an oil change, the Oil Life
Indicator must be reset. SeeOil Life Indicator on
page 3-74. SeeEngine Oil on page 5-13.
CHANGE TRANS FLUID – 47:This message will
appear when it is time to change the transaxle fluid. See
Scheduled Maintenance on page 6-4for the proper
fluid and change intervals.
CHECK BRAKE FLUID – 37:This message will
display if the ignition is in ON to inform the driver that
the brake fluid 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 3-43.
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 5-23.
CHECK FUEL GAGE – 50: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.
CHECK OIL LEVEL – 36:For correct operation of the
low oil sensing system, your vehicle should be on a
level surface. A false CHECK OIL LEVEL message may
appear if the vehicle is parked on a grade. The oil
level sensing system does not check for actual oil level
if the engine has been off for a short period of time,
and the oil level is never checked while the engine is
running. If the CHECK OIL LEVEL message appears,
and your vehicle has been parked on level ground
with the engine off for at least 30 minutes, the oil level
should be checked by observing the oil dipstick. Prior to
checking the oil level, be sure the engine has been
off for a few minutes and your vehicle is on a level
surface. Then check the dipstick and add oil if
necessary. SeeEngine Oil on page 5-13.
3-56

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

is activating the personalization feature. It will only
stay on for five 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 5-26.
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

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 5-26. 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
®

Filling a Portable Fuel Container
{CAUTION:
Never fill a portable fuel container while it is in
your vehicle. Static electricity discharge from
the container can ignite the gasoline vapor.
You can be badly burned and your vehicle
damaged if this occurs. To help avoid injury to
you and others:
•Dispense gasoline only into approved
containers.
•Do not fill a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed or
on any surface other than the ground.
•Bring the fill nozzle in contact with the
inside of the fill opening before operating
the nozzle. Contact should be maintained
until the filling is complete.
•Do not smoke while pumping gasoline.
Checking Things Under
the Hood
{CAUTION:
An electric fan under the hood can start up
and injure you even when the engine is not
running. Keep hands, clothing and tools away
from any underhood electric fan.
{CAUTION:
Things that burn can get on hot engine parts
and start a fire. These include liquids like fuel,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or
others could be burned. Be careful not to drop
or spill things that will burn onto a hot engine.

If the CHECK OIL LEVEL message appears on the
instrument cluster, it means you need to check
your engine oil level right away. For more information,
see “CHECK OIL LEVEL” underDIC Warnings and
Messages on page 3-55.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don’t, the oil
dipstick might not show the actual level.
