Engine Coolant HeaterThe engine coolant heater can provide easier starting
and better fuel economy during engine warm-up in cold
weather conditions at or below 0°F (−18°C). Vehicles
with an engine coolant heater should be plugged
in at least four hours before starting.To Use the Engine Coolant Heater1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is attached to the underside of the
diagonal brace, which is located above the
engine air cleaner/filter assembly.
3. Plug it into a normal, grounded 110-volt AC outlet.
{
WARNING:
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, and prevent damage.
The length of time the heater should remain plugged in
depends on several factors. Ask a dealer/retailer in
the area where you will be parking the vehicle for the
best advice on this.

R (Reverse):Use this gear to back up.
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice,
or Snow on page 5-19.
N (Neutral):In this position, the engine does not
connect with the wheels. To restart the engine when the
vehicle is already moving, use N (Neutral) only. Also,
use N (Neutral) when the vehicle is being towed.
{
WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage
the transmission. The repairs would not be covered
by the vehicle warranty. Be sure the engine is
not running at high speed when shifting the vehicle.
D (Drive):This position is for normal driving. It
provides the best fuel economy. If you need more
power for passing, and you are:
•
Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
•
Going about 35 mph (55 km/h) or more, push the
accelerator pedal all the way down.
The transmission will shift down to the next gear and
the vehicle will have more power.

Instrument Panel ClusterThe instrument panel cluster is designed to show how the vehicle is running. It shows how fast the vehicle is going,
about how much fuel has been used and many other things needed to drive safely and economically.

Tire Pressure LightFor vehicles with a tire pressure monitoring system,
this light comes on briefly when the engine is started.
It provides information about tire pressures and the
Tire Pressure Monitoring System.When the Light is On SteadyThis indicates that one or more of the tires are
significantly underinflated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDriver
Information Center (DIC) on page 4-37for more
information. Stop and check the tires as soon as it is safe
to do so. If underinflated, inflate to the proper pressure.
SeeInflation - Tire Pressure on page 6-59for more
information.
When the Light Flashes First and Then is
On SteadyThis indicates that there may be a problem with the Tire
Pressure Monitor System. The light flashes for about
a minute and stays on steady for the remainder of
the ignition cycle. This sequence repeats with every
ignition cycle. SeeTire Pressure Monitor Operation
on page 6-62for more information.Malfunction Indicator LampCheck Engine LightA computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It ensures that emissions are at acceptable levels
for the life of the vehicle, helping to produce a cleaner
environment.
This light should come on
when the ignition is on, but
the engine is not running,
as a check to show it
is working. If it does not,
have the vehicle serviced
by your dealer/retailer.
4-31

If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light
can prevent more serious damage to the vehicle.
This system assists the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is continually driven with
this light on, after a while, the emission controls
might not work as well, the 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 the vehicle warranty.
Notice:Modifications made to the engine,
transmission, exhaust, intake, or fuel system of the
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect the vehicle’s emission
controls and can cause this light to come on.
Modifications to these systems could lead to
costly repairs not covered by the vehicle warranty.
This could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 6-3.This light comes on during a malfunction in one of
two ways:
Light Flashing:A misfire condition has been detected.
A misfire increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.
To prevent more serious damage to the vehicle:
•
Reduce vehicle speed.
•
Avoid hard accelerations.
•
Avoid steep uphill grades.
•
If towing a trailer, reduce the amount of cargo being
hauled as soon as it is possible.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the key off, wait at least 10 seconds, and restart
the engine. If the light is still flashing, follow the previous
steps and see your dealer/retailer for service as soon
as possible.
4-32

Light On Steady:An emission control system
malfunction has been detected on the vehicle.
Diagnosis and service might be required.
An emission system malfunction might be corrected by
doing the following:•
Make sure the fuel cap is fully installed. SeeFilling
the Tank on page 6-10. The diagnostic system
can determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap
allows fuel to evaporate into the atmosphere. A few
driving trips with the cap properly installed should
turn the light off.
•
If the vehicle has been driven through a deep puddle
of water, the vehicle’s electrical system might be wet.
The condition is usually corrected when the electrical
system dries out. A few driving trips should turn the
light off.
•
Make sure to fuel the vehicle with quality fuel. Poor
fuel quality causes the engine not to run as efficiently
as designed and can cause: stalling after start-up,
stalling when the vehicle is changed into gear,
misfiring, hesitation on acceleration, or stumbling on
acceleration. These conditions might go away once
the engine is warmed up.
If one or more of these conditions occurs, change the
fuel brand used. It will require at least one full tank of
the proper fuel to turn the light off.
SeeGasoline Octane on page 6-6.
If none of the above have made the light turn off, your
dealer/retailer can check the vehicle. The dealer/retailer
has the proper test equipment and diagnostic tools to
fix any mechanical or electrical problems that might have
developed.

Highbeam On Light
This light comes on when
the high-beam headlamps
are in use.
SeeHeadlamp High/Low-Beam Changer on page 4-5
for more information.
Fuel GageWhen the ignition is on, the fuel gage indicates about
how much fuel is left in the fuel tank.An arrow on the fuel gage indicates the side of the
vehicle the fuel door is on.
Here are four things that some owners ask about.
None of these show a problem with the fuel gage:
•
At the gas station, the gas pump shuts off before the
gage reads full.
•
It takes a little more or less fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the fuel tank’s capacity
to fill the tank.
•
The gage moves a little when while turning a corner
or speeding up.
•
The gage does not go back to empty when the
ignition is turned off.
