Warm-Up Assist Function
此功能通过使变矩器失速，可在寒冷天气下帮助预热发动机和变速箱。 从"空档"或"驻车档"选择档位 "2R" 将会触发预热辅助模式。
此外，如果满足以下条件，在变速箱处于"驻车档"的情况下接地失速启用开关也会触发预热辅助模式：
- 变速箱油温低于 87.7 °C (190 °F)。
- 变矩器油温低于 110.0 °C (230 °F)。
- 发动机转速低于 1000 rpm 但高于 500 rpm。
注: 循环计时器用于控制变矩器的失速时间。 变矩器的允许失速时间为每 60 秒一次。
换出 "2R" 档将会解除预热辅助模式。 然后变速箱将恢复正常运转。
