®
activates continuously for an extended
period of time.
•
The message also displays if the brake system
warning light is on. See
Light on page 3-39
.
•
The message could display if the stability system
takes longer than usual to complete its diagnostic
checks due to driving conditions.
•
The message displays if an engine or vehicle
related problem has been detected and the vehicle
needs service. See your dealer/retailer.
•

TIGHTEN GAS CAP
This message may display along with the check engine
light on the instrument panel cluster if the vehicle’s fuel
cap is not tightened properly. See
Lamp on page 3-43
. Reinstall the fuel cap fully. See
Filling 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 this light and
message off.
TIRE LEARNING ACTIVE
This message displays when the Tire Pressure Monitor
System (TPMS) is re-learning the tire positions on
your vehicle. The tire positions must be re-learned after
rotating the tires or after replacing a tire or sensor.
See
Tire Inspection and Rotation on page 5-70
,
