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 320.
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.

Daytime Running Lamps (DRL)
Indicator Light
This light turns on
whenever the Daytime
Running Lamps are on.
SeeDaytime Running Lamps (DRL) on page 167
for more information.
Fuel Gage
When the ignition is on,
the fuel gage tells you
about how much
fuel you have remaining
in the fuel tank.Here are four things that some owners ask about.
None of these indicate a problem with your
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 ll 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 tank’s capacity to ll the tank.
The gage moves a little when you turn a
corner or speed up.
The gage does not go back to empty when
you turn off the ignition.
When the fuel in the fuel tank is low, you will see
a LOW FUEL message on the Driver Information
Center (DIC) display. SeeDIC Warnings and
Messages on page 198for more information.

FUEL CAP
This message displays if the vehicle’s fuel cap is
either off or loose. Pull over as soon as possible
and check to see if the fuel cap is secure. You may
also see the check engine light on the instrument
panel cluster. If the check engine light does
come on when the fuel cap was loose, it may take
a few driving trips before the light turns off. See
Malfunction Indicator Lamp on page 188for more
information if the light still remains on. Press
and release the reset stem to acknowledge the
message and clear it from the display.
LOW FUEL
This message displays if the level of fuel in
the vehicle is low. Also check the fuel gage. See
Fuel Gage on page 193for more information.
Rell the fuel tank as soon as possible.
LOW TIRE
This message displays if a low tire pressure
is detected in any of the vehicle’s tires. Press
and release the reset stem to acknowledge
the message and clear it from the display.The message appears at each ignition cycle
until the tires are inated to the correct
ination pressure. SeeTires on page 369and
Ination - Tire Pressure on page 377for
more information on tires and the correct
ination pressures.
LOW TRAC (Traction)
If your vehicle has the Traction Control
System (TCS), this message displays when a
low traction condition is detected. SeeTraction
Control System (TCS) on page 249for more
information. Press and release the reset stem to
acknowledge the message and clear it from
the display.
OIL
This message displays when the oil pressure is
low. SeeOil Pressure Light on page 191and
Engine Oil on page 325for more information.

Refer to your vehicle’s Tire and Loading Information
label for specic information about your vehicle’s
capacity weight and seating positions. The
combined weight of the driver, passengers, cargo,
and any accessories or equipment added to your
vehicle after it left the factory should never exceed
your vehicle’s capacity weight.
Certication/Tire Label
A vehicle specic Certication/Tire label is attached
to the bottom section of the center pillar, on the
driver’s side of the vehicle. Vehicles without a
center pillar, like extended cab models, will have
the Certication/Tire label attached to the edge of
the driver’s side, extended cab door, below the door
latch post. The label shows the Gross Vehicle
Weight Rating (GVWR). The GVWR includes the
weight of the vehicle, all occupants, fuel, cargo, and
trailer tongue weight, if pulling a trailer.

If the tow vehicle will not be started or driven
for six weeks or more, remove the battery
cable from the negative terminal (post) of the
battery to prevent your battery from draining
while towing.
After towing, see “Shifting Out of NEUTRAL”
underFour-Wheel Drive on page 126.
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.
Pull a trailer only if you have followed all
the steps in this section. Ask your dealer
for advice and information about towing
a trailer with your vehicle.Notice:Pulling a trailer improperly can
damage your vehicle and result in costly
repairs that would not be covered by your
warranty. Always follow the instructions in this
section and check with your dealer for more
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.
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.

The tethered fuel cap is located behind a hinged
fuel door on the driver’s side of the vehicle.
To remove the fuel cap, turn it slowly
counterclockwise.
While refueling, hang the tethered fuel cap from
the hook on the fuel door.
{CAUTION:
If you spill fuel and then something ignites
it, you could be badly burned. Fuel can
spray out on you if you open the fuel cap
too quickly. This spray can happen if your
tank is nearly full, and is more likely in hot
weather. Open the fuel cap slowly and wait
for any hiss noise to stop. Then unscrew
the cap all the way.
Be careful not to spill fuel. Do not top off or overll
the tank and wait a few seconds after you have
nished pumping before removing the nozzle.
Clean fuel from painted surfaces as soon
as possible. SeeWashing Your Vehicle on
page 419.
When replacing the fuel cap, turn it clockwise until
it clicks. Make sure the cap is fully installed.
The diagnostic system can determine if the fuel
cap has been left off or improperly installed.
