SERVICE INFORMATION

02M/01-1 RECALLS AND SERVICE CAMPAIGNS: WHEN REPAIRING ANY VEHICLE, ALWAYS CHECK THE VEHICLE MASTER INQUIRY FOR OPEN CAMPAIGNS.

02M/01-2 GROUP 80 - MODEL 163, EXCESSIVE KEYCHAIN WEIGHT: Clients with large, heavy key chains attached to the remote key may experience inadvertent switching off of the ignition.

In some cases, such as on rough roads, the weight of objects on the keychain may overcome the key folding detent force, causing the key to begin to fold closed. The partially closed key may then act as a lever, which can in some cases have sufficient torque to partially turn the ignition switch towards the off position.

In case of client complaints, please ensure that only lightweight objects are attached to the remote key. A new remote key, with a higher folding force, was introduced into production as of December 18, 2000, VIN #245145. Only keys with the higher folding force are supplied by Spare Parts. These keys may be ordered as replacements to help in circumstances where key chain weight may be problematic, although clients should be advised that sufficient folding forces may still be generated where key chain weight is excessive.
