2. If it doesn't start within 10 seconds, hold your key in
START for about 10 seconds at a time until your
engine starts. Wait about 15 seconds between
each try.
3. If your engine still won't start (or starts but then
stops), it could be ¯ooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
¯oor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
brie¯y but then stops again, do the same thing.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly.
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 Location
2-26

In very cold weather, 0ÉF (-18ÉC) 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. At
temperatures above 32ÉF (0ÉC), use of the coolant
heater is not required.
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.
CAUTION: (Continued)
CAUTION: (Continued)
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 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.

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.
See
Engine Overheating on page 5-28.
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. See
Engine
Overheating on page 5-28.
United StatesCanada

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. See
Oil Life Indicator on
page 3-77. SeeEngine Oil on page 5-13.
CHANGE TRANS FLUID ± 47:This message will
appear when it is time to change the transaxle ¯uid. See
Part A: Scheduled Maintenance Services 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. See
Brake
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. See
Engine Coolant on page 5-25.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's 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. See
Engine Oil on page 5-13.
3-57

CHECK WASHER FLUID ± 25:This message means
that your vehicle is low on windshield washer ¯uid.
See
Windshield Washer Fluid on page 5-39.
DRIVER DOOR AJAR ± 140:This message will
display anytime the key is in ON, the transaxle is not in
PARK (P) and the driver's door is open or ajar. A
chime will sound when the vehicle's speed is greater
than 3 mph (4.8 km/h).
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 262ÉF (128ÉC). 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. See
Engine Overheating on page 5-28.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. See
Engine Overheating on
page 5-28. 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.

Filling a Portable Fuel Container
{CAUTION:
Never ®ll 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 ®ll 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 ®ll nozzle in contact with the
inside of the ®ll opening before operating
the nozzle. Contact should be maintained
until the ®lling 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 ®re. These include liquids like fuel,
oil, coolant, brake ¯uid, windshield washer and
other ¯uids, 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.

see ªCHECK OIL LEVELº under
DIC Warnings and
Messages on page 3-56.
You should check your engine oil level regularly; this is
an added reminder.
