DIC Warnings and Messages
Messages are displayed on the DIC to notify the driver
that the status of the vehicle has changed and that
some action may be needed to correct the condition.
Multiple messages may appear one after another.
Some messages may not require immediate action.
Press any of the DIC buttons on the steering wheel or
the trip odometer reset stem on the instrument panel
cluster to acknowledge that you received the messages
and to clear them from the display.
Some messages cannot be cleared from the display
because they are more urgent. These messages require
action before they can be removed from the DIC
display. Take any messages that appear on the display
seriously and remember that clearing the messages
will only make the messages disappear, not correct the
problem.
The following are the possible messages that can be
displayed and some information about them.
3-51

CHANGE ENGINE OIL
This message displays when the engine oil needs to be
changed and service is required for your vehicle.
SeeScheduled Maintenance on page 6-4andEngine
Oil on page 5-15for more information. Also see
Engine Oil Life System on page 5-18for information
on how to reset the message. This message clears itself
after 10 seconds until the next ignition cycle.
CHECK TIRE PRESSURE
On vehicles with the Tire Pressure Monitor System
(TPMS), this message displays when the pressure in
one or more of the vehicle’s tires needs to be checked.
If a tire pressure message appears on the DIC, stop
as soon as you can. Have the tire pressures checked
and set to those shown on the Tire Loading Information
label. SeeTires on page 5-53,Loading the Vehicle
on page 4-31, andInflation - Tire Pressure on
page 5-60. The DIC also shows the tire pressure
values. SeeDIC Operation and Displays on page 3-48.
If the tire pressure is low, the low tire pressure
warning light comes on. SeeTire Pressure Light on
page 3-38.
CHECK WASHER FLUID
This message displays if the washer uid level is low.
Adding washer uid to the windshield washer uid
reservoir clears this message. SeeWindshield Washer
Fluid on page 5-34. This message clears itself after
10 seconds, or you can manually clear it from the
DIC display.
DRIVER DOOR AJAR
This message displays and a chime sounds if the driver
door is not fully closed. Stop and turn off the vehicle,
check the door for obstructions, and close the door
again. Check to see if the message still appears
on the DIC.

OVERHEATED
Notice:If you drive your vehicle while the engine
is overheating, severe engine damage may occur.
If an overheat warning appears on the instrument
panel cluster and/or DIC, stop the vehicle as soon as
possible. Do not increase the engine speed above
normal idling speed. SeeEngine Overheating
on page 5-30for more information.

Tire Inspection and Rotation
We recommend that you regularly inspect your
vehicle’s tires, including the spare tire, if the vehicle
has one, for signs of wear or damage. SeeWhen It
Is Time for New Tires on page 5-69for more
information.
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km). SeeScheduled Maintenance
on page 6-4.
The purpose of a regular tire rotation is to achieve
a uniform wear for all tires on the vehicle. This
will ensure that your vehicle continues to perform
most like it did when the tires were new.
Any time you notice unusual wear, rotate your
tires as soon as possible and check wheel
alignment. Also check for damaged tires or wheels.
SeeWhen It Is Time for New Tires on page 5-69
andWheel Replacement on page 5-74.When rotating your tires, always use the correct
rotation pattern shown here.
After the tires have been rotated, adjust the front
and rear ination pressures as shown on the Tire
and Loading Information label. SeeInflation - Tire
Pressure on page 5-60andLoading the Vehicle on
page 4-31.
Reset the Tire Pressure Monitor System. SeeTire
Pressure Monitor Operation on page 5-64.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specifications on page 5-120.

Scheduled Maintenance
When the change engine oil light or CHANGE ENGINE
OIL DIC message displays, service is required for the
vehicle. SeeChange Engine Oil Light on page 3-43or
DIC Warnings and Messages on page 3-51. Have the
vehicle serviced as soon as possible within the next
600 miles (1 000 km). It is possible that, if driving under
the best conditions, the engine oil life system may not
indicate that vehicle service 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 service technicians
who will perform this work using genuine parts and reset
the system.
If the engine oil life system is ever reset accidentally,
service the vehicle within 3,000 miles (5 000 km)
since the last service. Remember to reset the oil life
system whenever the oil is changed. SeeEngine Oil Life
System on page 5-18for information on the Engine
Oil Life System and resetting the system.When the change engine oil light or CHANGE ENGINE
OIL DIC message appears, certain services, checks,
and inspections are required. Required services are
described in the following for “MaintenanceI” and
“MaintenanceII.” Generally, it is recommended that the
rst service be MaintenanceI, the second service be
MaintenanceII, and then alternate MaintenanceIand
MaintenanceIIthereafter. However, in some cases,
MaintenanceIImay be required more often.
MaintenanceI— Use MaintenanceIif the light or
message displays within 10 months since the vehicle
was purchased or MaintenanceIIwas performed.
MaintenanceII— Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
MaintenanceIIwhenever the light or message displays
10 months or more since the last service or if the
light or message has not come on at all for one year.
