ECO (Fuel Saver Indicator) — If Equipped
The ECO indicator will illuminate when you are driving
in a fuel efficient manner and can be used to modify
driving habits in order to increase fuel economy. The
ECO display will toggle on and off depending on driving
habits and vehicle usage.
Rear Wheel Drive (RWD) / All Wheel Drive (AWD)
Displays (Base Cluster)
On vehicles equipped with a Base Instrument Cluster, the
odometer will display "2drivE" when the vehicle is in
Rear Wheel Drive (RWD), and "4drivE" when All Wheel
Drive (AWD) is activated.
If the odometer displays the "tCASE" warning message
after engine start up, or during driving, the AWD system
is not functioning properly and service is required.
NOTE: Vehicles equipped with Electronic Vehicle Infor-
mation Center (EVIC) will display "ALL WHEEL
UNDERSTANDING YOUR INSTRUMENT PANEL 211
DRIVE" and "REAR WHEEL DRIVE" when the appro-
priate condition exists. The EVIC will display "SERVICE
AWD SYSTEM" if the system is not functioning properly
and service is required. Refer to "Electronic Vehicle
Information Center (EVIC)" in this section for more
information.
gASCAP
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
"gASCAP" message will display in the odometer display
area. Tighten the fuel filler cap properly and press the
TRIP ODOMETER button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the Malfunction Indicator Light (MIL).
