An arrow on the fuel gage indicates
the side of the vehicle the fuel
door is on.
Here are three things that can
happen but do not indicate 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 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
turning a corner or speeding up.
When the fuel in the fuel tank is low,
a LOW FUEL message displays
on the Driver Information
Center (DIC). SeeDIC Warnings
and Messages on page 3-37
for more information.

When the system has calculated
that oil life has been diminished,
it indicates that an oil change
is necessary. A CHANGE OIL
message comes on. SeeDIC
Warnings and Messages on
page 3-37. Change the oil as soon
as possible within the next
600 miles (1 000 km). It is possible
that, if driving under the best
conditions, the oil life system might
not indicate that an oil change is
necessary for over a year. However,
the engine oil and lter must be
changed at least once a year and
at this time the system must be
reset. Your dealer/retailer has
trained people who will perform this
work using genuine parts and reset
the system. It is also important
to check the oil regularly and keep it
at the proper level.
If the system is ever reset
accidentally, the oil must be
changed at 3,000 miles (5 000 km)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.How to Reset the Engine Oil
Life System
The Engine Oil Life System
calculates when to change the
engine oil and lter based on vehicle
use. Whenever the oil is changed,
reset the system so it can calculate
when the next oil change is required.
If a situation occurs where the oil is
changed prior to a CHANGE OIL
message being turned on, reset the
system.
To reset the Engine Oil Life system:
1. With the engine off, turn the
ignition to ON/RUN.
2. Press and release the stem in
the lower center of the
instrument cluster until the OIL
LIFE message is displayed.
3. Once the alternating OIL LIFE
and RESET messages appear,
press and hold the stem until
several beeps sound. This
conrms that the oil life system
has been reset.
4. Turn the key to LOCK/OFF.If the CHANGE OIL message
comes back on when the vehicle is
started, the engine oil life system
has not reset. Repeat the procedure.
SeeDIC Warnings and Messages
on page 3-37.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer’s warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your own
oil, be sure to drain all the oil from the
lter before disposal. Never dispose
of oil by putting it in the trash, pouring
it on the ground, into sewers, or into
streams or bodies of water. Recycle
it by taking it to a place that collects
used oil.
5-16 Service and Appearance Care

Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn
the driver when a low tire pressure
condition exists. TPMS sensors
are mounted onto each tire and
wheel assembly on the vehicle,
excluding the spare tire. The TPMS
sensors monitor the air pressure
in the vehicle’s tires and transmit the
tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light
located on the instrument panel
cluster.At the same time, a Driver
Information Center (DIC) message
is displayed on the DIC display
screen. The low tire pressure
warning light and the DIC warning
message come on at each
ignition cycle until the tires are
inated to the correct ination
pressure. For additional information
and details about the DIC operation
and displays seeDIC Operation and
Displays on page 3-34andDIC
Warnings and Messages on
page 3-37.
The low tire pressure warning light
may come on in cool weather
when the vehicle is rst started, and
then turn off as you start to drive.
This could be an early indicator that
the air pressure in the tire(s) are
getting low and need to be inated
to the proper pressure.A Tire and Loading Information
label, attached to the vehicle, shows
the size of the vehicle’s original
equipment tires and the correct
ination pressure for the vehicle’s
tires when they are cold. See
Loading the Vehicle on page 4-35,
for an example of the Tire and
Loading Information label and its
location on the vehicle. Also see
Inflation - Tire Pressure on
page 5-51.
The vehicle’s TPMS can warn you
about a low tire pressure condition
but it does not replace normal
tire maintenance. SeeTire
Inspection and Rotation on
page 5-57andTires on page 5-44.
Notice:Liquid tire sealants
could damage the Tire Pressure
Monitor System (TPMS) sensors.
Sensor damage caused by using
a tire sealant is not covered
by your warranty. Do not use
liquid tire sealants.
