Battery Replacement
Replace the battery if the KEY FOB BATT LOW
message displays in the DIC. See “KEY FOB BATT
LOW” underDIC Warnings and Messages on page 3-44
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.
To replace the battery in the RKE transmitter:
1. Separate the halves of the transmitter with a at,
thin object inserted into the notch on the side.
2. Remove the old battery. Do not use a metal object.3. Insert the new battery, positive side facing up.
Replace with a CR2032 or equivalent battery.
4. Put the transmitter back together tightly.
Remote Vehicle Start
Your vehicle may have a remote start 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. When you start your vehicle using
the remote start feature, the climate control system
will come on and adjust the interior to the temperature
settings that you left it set to when you turned the
vehicle off.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require a
person using 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.
The remote start feature provides two separate starts
per ignition cycle, each with 10 minutes of engine
running time.

Engine Coolant Heater
The engine coolant heater, if available, can help in cold
weather conditions at or below 0°F (−18°C) for easier
starting and better fuel economy during engine warm-up.
Plug in the coolant heater at least four hours before
starting your vehicle. An internal thermostat in the
plug-end of the cord may exist which will prevent
engine coolant heater operation at temperatures
above 0°F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. For
the 2.2L and 2.4L engines, the electrical cord is
located on the passenger’s side of the vehicle
between the strut and the air cleaner/lter.
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
a dealer/retailer in the area where you will be parking
your vehicle. The dealer/retailer can give you the
best advice for that particular area.
2-26

DRIVE (D):This position is for normal driving with the
automatic transmission. 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), push your
accelerator all the way down.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 4-15.
INTERMEDIATE (I):This position is also used for
normal driving. However, it reduces vehicle speed
without using your brakes for slight downgrades where
the vehicle would otherwise accelerate due to
steepness of grade. If constant upshifting or
downshifting occurs while driving up steep hills, this
position can be used to prevent repetitive types of shifts.
You might choose INTERMEDIATE (I) instead of
DRIVE (D) when driving on hilly, winding roads and
when towing a trailer, so that there is less shifting
between gears.LOW (L):This position reduces vehicle speed more
than INTERMEDIATE (I) without actually using
your brakes. You can use it on very steep hills, or in
deep snow or mud. If the shift lever is put in LOW (L),
the transmission will not shift into LOW (L) 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 transmission. The repair will
not be covered by your warranty. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
2-29

Shift Speeds
{CAUTION:
If you skip a gear when you downshift, you
could lose control of your vehicle. You could
injure yourself or others. Do not shift down
more than one gear at a time when you
downshift.
Up-Shift Light
If you have a manual
transmission, you may
have an up-shift light. This
light will show you when
to shift to the next
higher gear for the best
fuel economy.
When this light comes on, you can shift to the next
higher gear if weather, road, and traffic conditions let
you. For the best fuel economy, accelerate slowly
and shift when the light comes on.
While you accelerate, it is normal for the light to go on
and off if you quickly change the position of the
accelerator. Ignore the light when you downshift.United States Only

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, about how much fuel is left in the tank, and many other things you will need to drive safely and
economically.

When the Light Flashes First and Then
is Solid
This indicates that there may be a problem with the Tire
Pressure Monitor System. The light ashes for about
a minute and stays on solid for the remainder of
the ignition cycle. This sequence will repeat with every
ignition cycle. SeeTire Pressure Monitor System on
page 5-56for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation of
the fuel, ignition, and emission control systems. It makes
sure 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 an OBD II
problem and service is
required.Malfunctions often are indicated by the system before
any problem is apparent. This can 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 a while, the emission controls
might not work as well, your vehicle’s fuel economy
might not be as good, and the engine might not
run as smoothly. This could lead to costly repairs
that might not be covered by your warranty.
Notice:Modications made to the engine,
transmission, 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 can cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This could
also result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 5-3.
