One-to-Four Shift Light (Manual Transmission) When this light comes on, the vehicle can only be shifted from 1 (First) to 4 (Fourth) instead of 1 (First) to 2 (Second). This light comes on when: • The engine coolant temperature is higher than 169°F (76°C), • The vehicle is going 15 to 19 mph (24 to 31 km/h) and • The vehicle 21 percent throttle or less. Brake System Warning Light The vehicle's hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop the vehicle. For good braking both parts need to be working well. The shift must be completed into 4 (Fourth) to turn off this feature. This helps the vehicle get the best possible fuel economy. After shifting to 4 (Fourth), the vehicle can be downshifted to a lower gear. Notice: Forcing the shift lever into any gear except 4 (Fourth) when the 1 TO 4 SHIFT light comes on may damage the transmission. Shift only from 1 (First) to 4 (Fourth) when the light comes on.
