Note to lessors receiving this recall: Federal regulation requires that you forward this recall notice to the lessee within 10 days. 

OWNER'S MANUAL ADDENDUM

"HOTOIL" Transmission Temperature Warning Message 

The "HOTOIL" cluster message accompanied with a continuous audible chime indicates that there is excessive transmission fluid temperature that might occur with severe usage such as trailer towing. It may also occur when operating the vehicle in a high torque converter slip condition, such as 4-wheel-drive operation (e.g., snow plowing, off- road operation). If this "HOTOIL" message accompanied with a continuous chime comes on, stop the vehicle and run the engine at idle or faster, with the transmission in NEUTRAL until the light turns off.

CAUTION: Continuous driving with the Transmission Temperature "HOTOIL" Warning message illuminated will eventually cause severe transmission damage or transmission failure.
WARNING: Continued operation with the Transmission Temperature "HOTOIL" Warning message illuminated could cause the fluid to boil over, come in contact with hot engine or exhaust components causing a fire that may result in personal injury.

Disabling Electronic Stability Program (ESP) for Modified Vehicles (4WD Models Only) 

Vehicles modified with larger tires and/or suspension lifts may experience early ESP activations as compared to a non-modified production vehicle depending on lift size, tire size, suspension changes and/or driving habits. If early ESP activations are experienced while driving a modified vehicle, the additional ability to permanently turn off ESP is available. A steering wheel/ESP button maneuver must be performed to permanently disable ESP and defeat the functionality of the ESP switch. Repeating the procedure will return the system to normal ESP operation and restore ESP switch functionality allowing ESP "Partial" or "Off" modes.

WARNING: With ESP in the permanent disable mode, enhanced vehicle stability offered by the ESP and Electronic Roll Mitigation (ERM) systems is unavailable. In an emergency evasive maneuver, the ESP and ERM systems will not engage to assist in maintaining stability. This disabled mode is intended for off-highway or off-road use only. Vehicle modifications requiring the owner to configure the vehicle in the ESP disabled mode will seriously affect the vehicle's roadworthiness and safety and may lead to loss of control and/or accident resulting in possible serious or fatal injuries.

The following procedure will disable (or re-enable) ESP functionality in the vehicle: 

  1. Shift the transfer case into the 4H range position.
  2. Turn the steering wheel until it is centered and the wheels are pointed straight ahead.
  3. Cycle the ignition key OFF to ON.
  4. Wait approximately five seconds for the system bulb check.
  5. Turn and hold the steering wheel one-half turn to the right (clockwise).
  6. Press and hold the ESP OFF button for seven seconds.
  7. Turn the steering wheel back to center, and turn and hold an additional one-half turn to the left (counter clockwise).
  8. Press and hold the ESP OFF button for seven seconds.
  9. Turn the steering wheel back to center.
  10. Press and hold the ESP OFF button for seven seconds.
  11. Cycle the ignition key to OFF.

After performing the ESP disable procedure correctly, "ESP OFF" will be displayed in the odometer for approximately 12 seconds each time the ignition is moved to ON. Repeating the ESP disable procedure will re-enable normal ESP operation.
