WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.
Only digital display
The speed can be generated with the engine idling and the gear selector in P/N position. If the gear selector is in any other position, a gear is engaged and the transmission input shaft is connected to the output shaft and an RPM will not be indicated until the car is driven. Depending on slippage in the torque converter the transmission speed and the engine speed will differ when the lock-up function is not engaged.
Measurement range (rpm): 0 - 8000.
