Customer Information Sheet (03/10/2011)

Your vehicle's Powertrain Control Module (PCM) has been updated with improved fault detection capabilities to minimize engine related repair costs. Below is a list of enhanced warning features in the new update:

• Water In Fuel Reduced Power Mode
• Engine Coolant Temperature Monitoring
• Overfilled Crankcase Detection (excessive oil level)
• Oil Cooler Efficiency Detection
• Turbocharger Overboost Detection

When a fault is detected in these areas, the PCM may implement the following:
• Wrench Light Illumination
• Reduce the Engine Power (limp home operation)
• Instrument Cluster Displays "reduced engine power"

If the vehicle exhibits one of these symptoms, you should return to your dealer for service. Refer to the Owner Guide for more information.

We understand that it may be inconvenient to take your vehicle in for service due to a warning light or limp-home operation. However, these warnings will help to avoid potential engine damage and time consuming, costly service repairs.

Also, if your Instrument Cluster Message Center was not updated previously, it may now display new powertrain status information.

Automatic transmission equipped vehicles only: Your vehicle is equipped with an adaptive
transmission shift strategy which allows the vehicle's computer to learn the transmission's unique parameters and improve shift quality. When your PCM is updated, the adaptive strategy is reset and the computer will begin a re-learning process. This re-learning process may result in firmer than normal up shifts and downshifts for several days.
