Brea, California (6/29/06) - Suzuki has received field reports on 2005 and 2006 model LT-Z400 ATVs regarding erosion of the magnesium clutch cover in the sealing area adjacent to the water pump cavity. This erosion can affect the sealing ability of the clutch cover and in extreme cases allow engine coolant to contaminate the oil. While we have received reports of the erosion, very few cases of coolant seepage have occurred.

It is common that over time corrosion occurs in the cooling system of motor vehicles and periodic maintenance such as flushing and cleaning is required. Starting with the 2005 models, the clutch cover material for the LT-Z400 was changed from aluminum to magnesium. Suzuki engineers have determined that the erosion found in the 2005 and 2006 model LT-Z400 clutch cover is not normal and is a result of a chemical reaction between the magnesium alloy and the coolant. Suzuki has decided that the best long term solution is to conduct a Customer Satisfaction Program and replace the clutch cover with one constructed of aluminum. In addition to replacing the clutch cover, your dealer will replace the engine oil, the oil filter and the coolant at no cost to you.

Contact your Suzuki dealer to schedule an appointment for the Customer satisfaction Program service. Your dealer will then order replacement parts and schedule a service appointment for your LT-Z400 ATV. Parts are currently available for your dealer to order.

During your pre-ride inspection, if there is no indication of engine oil contamination (oil is milky in color)found and the engine coolant level is normal, it is OK to operate your ATV. If engine oil contamination is found or coolant level is abnormal, please contact your Suzuki dealer to make an appointment for this Customer Satisfaction Program service before operating your ATV.

If you do not reside near the dealer from whom you purchased your ATV, or you purchased your ATV from a private party, you can contact the nearest authorized Suzuki dealer to schedule an appointment for the service. You can obtain information about Suzuki dealers in your area by calling the toll-free dealer
locator telephone number of 800/828-7433.

To save yourself time and travel, do not bring your LT-Z400 to your Suzuki dealer until you have made an appointment. Please be aware that no other conditions or service is covered by the Customer Satisfaction Program. The cost of any additional service you ask your dealer to perform is your responsibility.

If you have an additional question that is not addressed in this letter, please do not hesitate to contact your Suzuki dealer or you may contact the American Suzuki Customer Service Department for assistance using the direct Customer Service telephone line at 714-572-1490. You will need to have your Vehicle
Identification Number ready when calling.

We apologize for any inconvenience this action may cause, but we are certain you understand Suzuki'sinterest in your satisfaction with your LT-Z400 ATV.

Sincerely,
American Suzuki Motor Corporation
