REVERSE (R): To back up, press the clutch pedal. After the vehicle stops, shift into REVERSE (R). Slowly let up on the clutch pedal as you press the accelerator pedal. If it is hard to shift, let the shift lever return to NEUTRAL and release the clutch pedal. Then press the clutch again and shift into REVERSE (R). Do not attempt to shift into the fifth gear position prior to shifting into REVERSE (R). Your transmission has a lock out feature which prevents a fifth gear to reverse gear shift. Notice: Shifting to REVERSE (R) while your vehicle is moving forward could damage the transmission. The repairs would not be covered by your warranty. Shift to REVERSE (R) only after your vehicle is stopped. Use REVERSE (R), along with the parking brake, for parking your vehicle. When this light comes on, you can shift to the next higher gear if weather, road and traffic conditions permit. For the best fuel economy, accelerate slowly and shift when the light comes on. While you accelerate, it is normal for the light to go on and off if you quickly change the position of the accelerator. Ignore the shift light when you downshift. If your vehicle has four-wheel drive and has a manual transmission, disregard the shift light when the transfer case is in four-wheel low. For more information, see Up-Shift Light (Manual Transmission) on page 181. Shift Speeds Up-Shift Light This light will show you when to shift to the next higher gear for best fuel economy. {CAUTION: If you skip a gear when you downshift, you could lose control of your vehicle.
