In Brief 1-21
Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS warning light alerts you
to a significant loss in pressure of
one of the vehicle's tires. If the
warning light comes on, stop as
soon as possible and inflate the
tires to the recommended pressure
shown on the Tire and Loading
Information label. SeeVehicle Load
Limits on page 9‑12. The warning
light will remain on until the tire
pressure is corrected.
During cooler conditions, the low tire
pressure warning light may appear
when the vehicle is first started and
then turn off. This may be an early indicator that the tire pressures are
getting low and the tires need to be
inflated to the proper pressure.
The TPMS does not replace normal
monthly tire maintenance. It is the
driver
’s responsibility to maintain
correct tire pressures.
See Tire Pressure Monitor System
on page 10‑47.Tire Sealant and
Compressor Kit
This vehicle may come with a jack
and spare tire or a tire sealant and
compressor kit. The kit can be used
to temporarily seal small punctures
in the tread area of the tire.
See Tire Sealant and Compressor
Kit on page 10‑63 for complete
operating information.
If the vehicle came with a jack and
spare tire, see If a Tire Goes Flat on
page 10‑61.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays the CHANGE ENGINE
OIL SOON message when it is time
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change.
Resetting the Oil Life System

Extending Engine Run Time
To extend the engine run time by
10 minutes, repeat Steps 1 though 3
while the engine is still running.
The engine run time can only be
extended if it is the first remote start
since the vehicle has been driven.
Remote start can be extended
one time.
If the remote start procedure is used
again before the first 10 minute
time frame has ended, the first
10 minutes will immediately expire
and the second 10 minute time
frame will start.For example, if the lock button and
then the remote start buttons are
pressed again after the vehicle
has been running for five minutes,
10 minutes are added, allowing
the engine to run for a total of
15 minutes.
A maximum of two remote starts or
remote start attempts are allowed
between ignition cycles.
After the vehicle's engine has been
started two times using the remote
start button, the ignition must be
turned on and then back off before

Instruments and Controls 5-23
Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the engine
is started. It provides information
about tire pressures and the TPMS.
When the Light is On Steady
This indicates that one or more
of the tires are significantly
underinflated.
A tire pressure message can
accompany the light. SeeTire
Messages on page 5‑44 for more
information. Stop as soon as
possible, and inflate the tires to
the pressure value shown on the
Tire and Loading Information label.
See Tire Pressure on page 10‑45
for more information. When the Light Flashes First and
Then is On Steady
This indicates that there may
be a problem with the TPMS.
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. See
Tire Pressure
Monitor Operation on page 10‑48
for more information.
Engine Oil Pressure Light
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced. Notice:
Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule for changing engine oil.
The oil pressure light should come
on briefly as the engine is started.
If it does not come on have the
vehicle serviced by your dealer.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem.

Vehicle Care 10-95
Interior Care
The interior will continue to look
its best if it is cleaned often.
Dust and dirt can accumulate on
the upholstery and cause damage
to the carpet, fabric, leather, and
plastic surfaces. Stains should be
removed quickly as extreme heat
could cause them to set rapidly.
Lighter colored interiors may
require more frequent cleaning.
Newspapers and garments that
can transfer color to home
furnishings can also transfer
color to the interior.
Remove dust from small buttons
and knobs with a small brush with
soft bristles.
Your dealer has products for
cleaning the interior. When
cleaning the interior, only use
cleaners specifically designed
for the surfaces that are being
cleaned. Permanent damage can
result from using cleaners on
surfaces for which they were notintended. Apply the cleaner directly
to the cleaning cloth to prevent
over-spray. Remove any accidental
over-spray from other surfaces
immediately.
Notice:
Using abrasive cleaners
when cleaning glass surfaces on
the vehicle, could scratch the
glass and/or cause damage to
the rear window defogger. When
cleaning the glass on the vehicle,
use only a soft cloth and glass
cleaner.
Cleaners can contain solvents that
can become concentrated in the
interior. Before using cleaners,
read and adhere to all safety
instructions on the label. While
cleaning the interior, maintain
adequate ventilation by opening
the doors and windows.
Do not clean the interior using the
following cleaners or techniques:
.Never use a knife or any other
sharp object to remove a soil
from any interior surface.
.Never use a stiff brush. It can
cause damage.
.Never apply heavy pressure or
rub aggressively with a cleaning
cloth. Use of heavy pressure can
damage the interior and does
not improve the effectiveness
of soil removal.
.Avoid laundry detergents
or dishwashing soaps with
degreasers. Using too much
soap will leave a residue that
leaves streaks and attracts
dirt. For liquid cleaners, about
20 drops per 3.78 L (1 gal) of
water is a good guide. Use only
mild, neutral-pH soaps.
.Do not heavily saturate the
upholstery while cleaning.
.Cleaners that contain solvents
can damage the interior.
