Warning lights and gauges can signal that  
something is wrong before it becomes  
serious enough to cause an expensive repair  
or replacement. Paying attention to the  
warning lights and gauges could prevent  
injury.

Gauge  
Caution  
Lack of proper engine oil maintenance  
can damage the engine. Driving with the  
engine oil low can also damage the  
engine. The repairs would not be covered  
by the vehicle warranty. Check the oil  
level as soon as possible. Add oil if  
required, but if the oil level is within the  
operating range and the oil pressure is  
still low, have the vehicle serviced.  
Always follow the maintenance schedule  
for changing engine oil.  
Oil pressure can vary with engine speed,  
outside temperature, coolant temperature,  
and oil viscosity.  
On some models, the oil pump will vary  
engine oil pressure according to engine  
needs. Oil pressure may change quickly as  
the engine speed or load varies. This is  
normal. If the oil pressure warning light or  
Driver Information Center (DIC) message  
indicates oil pressure outside the normal  
operating range, check the engine oil as  
soon as possible.

Then the light stays on solid until the belt is  
buckled. This cycle may continue several  
times if the driver remains or becomes  
unbuckled while the vehicle is moving.  
When the engine is running, this gauge

The gauge can transition from a higher to  
lower or a lower to higher reading. This is

If the airbag readiness light stays on  
after the vehicle is started or comes on  
while driving, it means the airbag system  
might not be working properly. The  
airbags in the vehicle might not inflate in

have the vehicle serviced right away.  
This light shows if there is an electrical  
problem with the airbag system. It is  
located in the instrument cluster. The  
system check includes the airbag sensor(s),  
the passenger sensing system, the  
pretensioners, the airbag modules, the  
wiring, and the crash sensing and diagnostic  
module. For more information on the airbag  
system, see Airbag System 0 59.

seconds as a system check. Then, after  
several more seconds, the status indicator

Malfunction Indicator Lamp  
(Check Engine Light)  
Charging System Light  
This light is part of the vehicles emission  
control on-board diagnostic system. If this  
light is on while the engine is running, a  
malfunction has been detected and the  
vehicle may require service. The light should  
come on to show that it is working when  
the ignition is on and the engine is not  
running. See Ignition Positions 0 211.  
If the word OFF, or the off symbol, is lit on  
the passenger airbag status indicator, it  
means that the passenger sensing system  
has turned off the front outboard passenger  
frontal airbag.  
If, after several seconds, both status  
indicator lights remain on, or if there are no  
lights at all, or if the airbag readiness light  
is on, there may be a problem with the  
lights or the passenger sensing system. See  
your dealer for service right away.  
The charging system light comes on briefly  
when the ignition is turned on, but the  
engine is not running, as a check to show  
the light is working. It should go out when  
the engine is started.  
If the light stays on, or comes on while  
driving, there may be a problem with the  
electrical charging system. Have it checked  
by your dealer. Driving while this light is on  
could drain the battery.

If the airbag readiness light ever comes  
on and stays on, it means that  
something may be wrong with the airbag  
system. To help avoid injury to yourself  
or others, have the vehicle serviced right

Poor fuel quality can cause inefficient  
engine operation and poor driveability,  
which may go away once the engine is  
warmed up. If this occurs, change the fuel  
brand. It may require at least one full  
tank of the proper fuel to turn the light  
off. See Recommended Fuel (6.2L  
To help prevent damage, reduce vehicle  
speed and avoid hard accelerations and  
uphill grades. If towing a trailer, reduce the  
amount of cargo being hauled as soon as  
possible.  
If the vehicle is driven continually with  
this light on, the emission control system  
may not work as well, the fuel economy  
may be lower, and the vehicle may not  
run smoothly. This could lead to costly  
repairs that might not be covered by the  
vehicle warranty.  
If the light continues to flash, find a safe  
place to park. Turn the vehicle off and wait  
at least 10 seconds before restarting the  
engine. If the light is still flashing, follow

If the light is on steady : A malfunction has  
been detected. Diagnosis and service may be  
required.  
Modifications to the engine, transmission,  
exhaust, intake, or fuel system, or the  
use of replacement tires that do not  
meet the original tire specifications, can  
cause this light to come on. This could  
lead to costly repairs not covered by the  
vehicle warranty. This could also affect  
the vehicles ability to pass an Emissions  
Inspection/Maintenance test. See  
If the vehicle requires an Emissions
