If the Light Is On Steady
You might 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 381.
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.
Did you just drive through a deep puddle of water?
If so, your 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.Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 379. Poor fuel
quality causes the engine not to run as efficiently
as designed. You might notice this as stalling
after start-up, stalling when you put the vehicle into
gear, mis ring, hesitation on acceleration, or
stumbling on acceleration — these conditions
might go away once the engine is warmed up. This
will be detected by the system and cause the
light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at
least one full tank of the proper fuel to turn the
light off.
If none of the above steps have made the light
turn off, your dealer/retailer can check the vehicle.
Your dealer/retailer has the proper test equipment
and diagnostic tools to x any mechanical or
electrical problems that might have developed.

Here are some situations you may experience with
your fuel gage. None of these indicate a problem
with the fuel gage.
At the gas station, the fuel pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than
the fuel 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 tank’s capacity to ll the tank.
The gage goes back to empty when you turn
off the ignition.
Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
The DIC displays information about your vehicle. It
also displays warning messages if a system
problem is detected.
All messages will appear in the DIC display
located at the top of the instrument panel cluster.
The DIC comes on when the ignition is on.
After a short delay, the DIC will display the
information that was last displayed before the
engine was turned off.The DIC also displays a shift lever position
indicator on the bottom line of the display. See
Automatic Transmission Operation on page 129for
more information.
The outside air temperature also displays on the
DIC when viewing the trip and fuel information.
The outside air temperature automatically appears
in the top right corner of the DIC display. If
there is a problem with the system that controls
the temperature display, the numbers will be
replaced with dashes. If this occurs, have
the vehicle serviced.
If your vehicle has DIC buttons, see “DIC
Operation and Displays (With DIC Buttons)” later
in this section andDIC Vehicle Customization
(With DIC Buttons) on page 250for the displays
available.
If your vehicle does not have DIC buttons, see
“DIC Operation and Displays (Without DIC
Buttons)” later in this section for the displays
available.

This message may display along with the check
engine light on the instrument panel cluster if
the vehicle’s fuel cap is not tightened properly. See
Malfunction Indicator Lamp on page 222.
Reinstall the fuel cap fully. SeeFilling the Tank on
page 381. 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 this
light and message off.

Towing a Trailer
{CAUTION:
If you do not use the correct equipment
and drive properly, you can lose control
when you pull a trailer. For example, if the
trailer is too heavy, the brakes may not
work well — or even at all. You and your
passengers could be seriously injured.
You may also damage your vehicle; the
resulting repairs would not be covered by
your warranty. Pull a trailer only if you
have followed all the steps in this section.
Ask your dealer/retailer for advice and
information about towing a trailer with
your vehicle.To identify the trailering capacity of your vehicle,
you should read the information in “Weight of
the Trailer” that appears later in this section. But
trailering is different than just driving your
vehicle by itself. Trailering means changes in
handling, acceleration, braking, durability and fuel
economy. Successful, safe trailering takes
correct equipment, and it has to be used properly.
That’s the reason for this part. In it are many
time-tested, important trailering tips and safety
rules. Many of these are important for your safety
and that of your passengers. So please read
this section carefully before you pull a trailer.
Load-pulling components such as the engine,
transmission, rear axle, wheel assemblies and tires
are forced to work harder against the drag of
the added weight. The engine is required
to operate at relatively higher speeds and under
greater loads, generating extra heat. What’s more,
the trailer adds considerably to wind resistance,
increasing the pulling requirements.
