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 9‑11. 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 10‑58.Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays a DIC message when
it is necessary 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
1. Turn the ignition to ON/RUN, with the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds. 3. Turn the key to LOCK/OFF.
See
Engine Oil Life System on
page 10‑10.

Remote Vehicle Start
This vehicle may have a remote
start feature. This feature allows you
to start the engine from outside the
vehicle. It may also start the
vehicle's heating or air conditioning
systems. See Climate Control
Systems on page 8‑1 for additional
information.
Laws in some local communities
may restrict the use of remote
starters. For example, some laws
may require a person using remote
start to have the vehicle in view
when doing so. Check local
regulations for any requirements on
remote starting of vehicles. Do not use the remote start
feature if the vehicle is low on fuel.
The vehicle may run out of fuel.
If the vehicle has the remote start
feature, the RKE transmitter
functions will have an increased
range of operation. However, the
range may be less while the vehicle
is running.
There are other conditions which
can affect the performance of the
transmitter, see
Remote Keyless
Entry (RKE) System on page 2‑3 for
additional information.

Vehicle Security
This vehicle has theft-deterrent
features; however, they do not
make it impossible to steal.
Immobilizer
SeeRadio Frequency Statement on
page 13‑22 for information
regarding Part 15 of the Federal
Communications Commission (FCC)
rules and Industry Canada
Standards RSS-GEN/210/220/310.
Immobilizer Operation
This vehicle is equipped with the
PASS-Key®III+ (Personalized
Automotive Security System)
theft-deterrent system.
PASS-Key III+ is a passive
theft deterrent system.
The system is automatically armed
when the key is removed from the
ignition. You do not have to manually arm or
disarm the system.
The security light will come on if
there is a problem with arming or
disarming the theft-deterrent
system.
When the PASS-Key III+ system
senses that someone is using the
wrong key, it shuts down the
vehicle's starter and fuel systems.
The starter will not work and fuel will
stop being delivered to the engine.
Anyone using a trial-and-error
method to start the vehicle will be
discouraged because of the high
number of electrical key codes.
If the engine does not start and the
security message comes on, the
key may have a damaged
transponder. Turn the ignition off
and try again.
If the engine still does not start, and
the key appears to be undamaged,
try another ignition key. At this time,
you may also want to check the
instrument panel PASS KEY fuse.
If the engine still does not start with
the other key, the vehicle needs
service. If the vehicle does start, the
first key may be faulty. See your
dealer or a locksmith who can
service the PASS-Key III+ to have a
new key made. See
Fuses and
Circuit Breakers on page 10‑41.
It is possible for the PASS-Key III+
decoder to learn the transponder
value of a new or replacement key.
Up to 10 keys may be programmed
for the vehicle. This procedure is for
learning additional keys only. If all
the currently programmed keys are
lost or do not operate, you must see
your dealer or a locksmith who can
service PASS-Key III+ to have keys
made and programmed to the
system.

5-22 Instruments and Controls
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, stop
and park the vehicle. Turn the
vehicle off, wait at least 10 seconds,
and restart the engine. If the light is
still flashing, follow the previous
steps and see your dealer for
service as soon as possible. Light On Steady:
An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might
be required.
The following may correct an
emission system malfunction:
.Check that the fuel cap is fully
installed. See Filling the Tank on
page 9‑44. 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.
.Check that good quality fuel is
used. Poor fuel quality causes
the engine not to run as
efficiently as designed and
may 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.
See Recommended Fuel on
page 9‑40.
If none of the above have made the
light turn off, your dealer can check
the vehicle. The dealer has the
proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.

system warning light also comes on
when the parking brake is set. See
Parking Brake on page 9‑34for
more information. The light stays on
if the parking brake does not fully
release. If it stays on after the
parking brake is fully released, it
means the vehicle has a brake

If the ABS light stays on, turn the
ignition off. If the light comes on
while driving, stop as soon as it is
safely possible and turn the ignition
off. Then start the engine again to
reset the system. If the ABS light
stays on, or comes on again while
driving, the vehicle needs service.
If the regular brake system warning
