This message displays when your vehicle’s throttle
system is not functioning properly. Have your vehicle
serviced by your dealer/retailer.
THEFT ATTEMPTED
This message displays if the content theft-deterrent
system has detected a break-in attempt while you were
away from your vehicle. See Content Theft-Deterrent

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 Malfunction
Indicator Lamp on page 3-50. Reinstall the fuel cap

cap allows fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn this light and message off.
