3. Slide the new battery into the transmitter with
the positive side of the battery facing down.
Use a type CR2032 battery, or equivalent
type. Make sure the cover is on tightly,
so water will not get in.
4. Snap the front and the back of the transmitter
together.
5. Test the operation of the transmitter with the
vehicle.
Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine from
outside the vehicle. It may also start the vehicle’s
heating or air conditioning systems, rear window
defogger, and heated seats. SeeHeated Seats on
page 11andHeated and Cooled Seats on page 12
for additional information. When the remote start
system is active, the climate control system will
heat or cool the inside of the vehicle at the setting
the vehicle was set to when the vehicle was last
turned off. The rear window defogger will be turned
on by the climate control system when it is cold
outside. If the vehicle has heated seats, they may
also turn on. Cooled seats are not activated during
a remote start. Normal operation of the system will
return after the key is turned to the RUN position.Laws in some communities may restrict the use of
remote starters. For example, some laws may
require a person using the remote start to have
the vehicle in view when doing so. Check local
regulations for any requirements on remote starting
of vehicles.
Do not use the remote start feature if your vehicle
is low on fuel. Your vehicle may run out of fuel.
If your vehicle has remote start, the RKE transmitter
provides, an increased range of operation.
However, the range may be less while the vehicle is
running. As a result, you may need to be closer to
your vehicle to turn it off, than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote
Keyless Entry (RKE) System on page 94for
additional information.
/(Remote Start):If your vehicle has the remote
start feature, the RKE transmitter will have a
button with this symbol on it.

2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator pedal all
the way to the oor and holding it there as you
hold the key in START for up to a maximum of
15 seconds. Wait at least 15 seconds between
each try, to allow the cranking motor to cool
down. When the engine starts, let go of the key
and accelerator. If the vehicle starts briey but
then stops again, do the same thing. This
clears the extra gasoline from the engine. Do
not race the engine immediately after starting
it. Operate the engine and transaxle gently
until the oil warms up and lubricates all
moving parts.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. Any resulting damage
would not be covered by your vehicle’s
warranty.
Engine Coolant Heater
If your vehicle has this feature, 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.
At temperatures above 32°F (0°C), use of the
coolant heater is not required.

DRIVE (D):This position is for normal driving. It
provides the best fuel economy for your vehicle. If
you need more power for passing, and you are:
Going less than about 35 mph (55 km/h), push
your accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push
the accelerator all the way down.
You will shift down to the next gear and have
more power.
Downshifting the transaxle in slippery road
conditions could result in skidding, see “Skidding”
underLoss of Control on page 290.
THIRD (3):This position is also used for normal
driving. It reduces vehicle speed more than
DRIVE (D) without using your brakes. You might
choose THIRD (3) instead of DRIVE (D) when
driving on hilly, winding roads, when towing
a trailer, so there is less shifting between gears
and when going down a steep hill.
SECOND (2):This position reduces vehicle speed
even more than THIRD (3) without using your
brakes. You can use SECOND (2) on hills. It can
help control your speed as you go down steep
mountain roads, but then you would also want to
use your brakes off and on.Notice:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph
(90 km/h) may damage the transaxle. Also,
shifting into SECOND (2) at speeds above
65 mph (105 km/h) can cause damage. Drive in
THIRD (3) or DRIVE (D) instead of SECOND (2).
FIRST (1):This position reduces vehicle speed
even more than SECOND (2) without using your
brakes. You can use it on very steep hills, or in
deep snow or mud. If the shift lever is put in
FIRST (1) while going forward, the transaxle will
not shift into rst gear until the vehicle is going
slowly enough.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only the
accelerator pedal may damage the transaxle.
If you are stuck, do not spin the tires. When
stopping on a hill, use the brakes, or parking
brake to hold the vehicle in place.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
that may be on your vehicle. The pictures will
help you locate them.
Warning lights and gages can signal that something
is wrong before it becomes serious enough to
cause an expensive repair or replacement. Paying
attention to your warning lights and gages could
also save you or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you
will see in the details on the next few pages, some
warning lights come on briey when you start the
engine just to let you know they are working. If you
are familiar with this section, you should not be
alarmed when this happens.
Gages can indicate when there may be or is a
problem with one of your vehicle’s functions.
Often gages and warning lights work together to
let you know when there is a problem with
your vehicle.When one of the warning lights comes on and stays
on when you are driving, or when one of the gages
shows there may be a problem, check the section
that tells you what to do about it. Please follow this
manual’s advice. Waiting to do repairs can be
costly — and even dangerous. So please get to
know your warning lights and gages. They are a
big help.
Your vehicle has a DIC that works along with the
warning lights and gages. SeeDriver Information
Center (DIC) on page 212.
Instrument Panel Cluster
Your instrument panel cluster is designed to let
you know at a glance how your vehicle is running.
You will know how fast you are going, how
much fuel you have, and many other things you
will need to drive safely and economically.
194

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation
of the fuel, ignition,
and emission control
systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The check engine light comes on to
indicate that there is a problem and service is
required. Malfunctions often will be indicated by
the system before any problem is apparent. This
may prevent more serious damage to your vehicle.
This system is also designed to assist your service
technician in correctly diagnosing any malfunction.Notice:If you keep driving your vehicle with
this light on, after awhile, your emission
controls may not work as well, your fuel
economy may not be as good, and your engine
may not run as smoothly. This could lead to
costly repairs that may not be covered by your
warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system of
your vehicle or the replacement of the original
tires with other than those of the same Tire
Performance Criteria (TPC) can affect your
vehicle’s emission controls and may cause
this light to come on. Modications to these
systems could lead to costly repairs not
covered by your warranty. This may also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 325.

This light should come on, as a check to show you it
is working, when the ignition is on and the engine is
not running. If the light does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and may damage the emission control system
on your vehicle. Diagnosis
and service may be required.
Light On Steady— An emission control
system malfunction has been detected on
your vehicle. Diagnosis and service may be
required.
If the Light Is Flashing
The following may prevent more serious damage
to your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possibleIf the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do
so, stop the vehicle. Find a safe place to park
your vehicle. Turn the key off, wait at least
10 seconds and restart the engine. If the light
remains on steady, see “If the Light Is On Steady”
following. If the light is still ashing, follow the
previous steps, and see your dealer for service
as soon as possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 330.
The diagnostic system can determine if the fuel cap
has been left off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere. A few driving trips with the cap
properly installed should turn the light off.
