Condition
Some owners of the above models may experience an initial delay when shifting into drive after the vehicle has gone through an overnight cold soak
usually at -12° C (10° F) ambient temperature or colder. This condition will not repeat until the vehicle has gone through another overnight cold soak.
During the initial delay, an increase to engine RPM could cause the engagement into forward gear to be harsh. (See Figure 1)
