# DELAYED ENGAGEMENT-CRUISE III MISDIAGNOSED AS MALFUNCTION

#### MODELS: ALL 1984-86 LIGHT DUTY MODELS EOUIPPED WITH CRUISE CONTROL (CUSTOM CRUISE III)

The Custom Cruise III system contains a built in delay feature which could be mis-diagnosed as a malfunctioning cruise control. Specifically, with this system, only after the multifunction lever switch has been in the "ON " position for approximately one to two seconds will the cruise control system engage - with depression of the set/coast button. The reason for this time delay is twofold:

- It allows ample opportunity for the cruise control module to correctly interpret vehicle speed.

- Secondly, an important safety consideration is yielded as well. This same delay prevents the cruise controller from storing an uncalled-for "set" speed.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
