Tire Pressure Light
For vehicles with a tire
pressure light, this light
comes on briey when the
engine is started and
provides information about
tire pressures and the
Tire Pressure Monitoring
System.
When the Light is On Steady
This indicates that one or more of the tires is signicantly
underinated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDIC
Warnings and Messages on page 3-54for more
information. Stop and check the tires as soon as it is
safe to do so. If a tire is underinated, inate to the
proper pressure. SeeTires on page 5-62for more
information.
When the Light Flashes First and Then is
On Steady
This indicates that there could be a problem with the
Tire Pressure Monitor System. The light ashes
for about a minute and stays on steady for the remainder
of the ignition cycle. This sequence repeats with every
ignition cycle. SeeTire Pressure Monitor System on
page 5-73for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation of
the fuel, ignition, and emission control systems. It makes
sure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment.
This comes on briey
while starting the engine.
If it does not come on,
have the vehicle serviced
by your dealer/retailer.
3-42

If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light
can prevent more serious damage to the vehicle.
This system assists the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is continually driven with
this light on, after a while, the emission controls
might not work as well, the vehicle’s fuel economy
might not be as good, and the engine might not
run as smoothly. This could lead to costly repairs
that might not be covered by the vehicle warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system of
the vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect the vehicle’s emission
controls and can cause this light to come on.
Modications to these systems could lead to
costly repairs not covered by the vehicle warranty.
This could also result in a failure to pass a
required Emission Inspection/Maintenance test.
SeeAccessories and Modifications on page 5-3.This light comes on during a malfunction in one of
two ways:
Light Flashing:A misre condition has been detected.
A misre increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.
The following can prevent more serious damage to the
vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If the light continues to ash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the key off, wait at least 10 seconds, and restart
the engine. If the light is still ashing, follow the previous
steps and see your dealer/retailer for service as soon
as possible.
3-43

Light On Steady:An emission control system
malfunction has been detected on the vehicle.
Diagnosis and service might be required.
An emission system malfunction might be corrected by
doing the following:
Make sure the fuel cap is fully installed. SeeFilling
the Tank on page 5-9. 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.
If the vehicle has been driven through a deep
puddle of water, the 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.
Make sure to fuel the vehicle with quality fuel.
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, misring, 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.
SeeGasoline Octane on page 5-6.
If none of the above have made the light turn off, your
dealer/retailer can check the vehicle. The dealer/retailer
has the proper test equipment and diagnostic tools to
x any mechanical or electrical problems that might have
developed.

Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
The vehicle will not pass this inspection if the check
engine light is on with the engine running.
To perform a check engine light bulb check with the
keyless ignition, make sure the transmitter fob is
in the passenger compartment. SeeIgnition
Positions on page 2-22. Press the bottom of the
Acc. button on the instrument panel and hold
the button down for ve seconds. The instrument
panel, including the check engine light, will light up
and the ignition will be on, but the engine will not
start — press the bottom of the Acc. button only
briey, less than ve seconds, the accessory power
mode will be turned on, but not the ignition.
After the bulb check, press and release the Acc.
button again to turn the ignition off and avoid
draining the vehicle’s battery.
The vehicle will not pass this inspection if the
OBD II (on-board diagnostic) system determines
that critical emission control systems have not been
completely diagnosed by the system. The vehicle
would be considered not ready for inspection.
This can happen if the battery has recently
been replaced or if the battery has run down.
The diagnostic system is designed to evaluate
critical emission control systems during normal
driving. This can take several days of routine
driving. If this has been done and the vehicle still
does not pass the inspection for lack of OBD II
system readiness, your dealer/retailer can prepare
the vehicle for inspection.

Fuel Gage
The fuel gage shows
how much fuel the vehicle
has left while the engine
is on.
An arrow on the fuel gage indicates the side of the
vehicle the fuel door is on.
When the needle approaches the low fuel symbol, a
chime sounds and LOW FUEL appears on the Driver
Information Center (DIC) display. There is still a little fuel
left, but the vehicle’s fuel tank should be lled soon.
Press the RESET button to acknowledge a DIC
message(s). Pressing the RESET button also turns off a
DIC message but the LOW FUEL message comes on
again in 10 minutes if fuel is not added to the vehicle.Here are ve things that some owners ask about.
All these things are normal and do not indicate that
anything is wrong with the fuel gage.
At the service station, the gas pump shuts off
before the gage reads the full.
It takes a little more or less fuel to ll up than the
gage indicated. For example, the gage may have
indicated half full, but it took a little more or
less than half of the tank’s capacity to ll the tank.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate the tank is empty when
the ignition is turned off.
The gage reading may change slightly within the
rst several minutes after starting the vehicle.
SeeDIC Operation and Displays on page 3-49for more
information.

Boost Gage (ZR1 Only)
For vehicles that have this gage, it is located near the
driver side of the instrument panel cluster.
This gage indicates vacuum during light to moderate
throttle and boost under heavier throttle.
It displays the air pressure level in the intake manifold
before it enters the engine’s combustion chamber.
The gage is automatically centered at zero every time
the engine is started. Actual vacuum or boost is
displayed from this zero point. Changes in ambient
pressure, such as driving in mountains and changing
weather, will slightly change the zero reading.
