This is the shift pattern for the six-speed manual transmission.

Here is how to operate the transmission:

1 (First): Press the clutch pedal and shift into 1 (First). Then slowly let up on the clutch pedal as you press the accelerator pedal. You can shift into 1 (First) when you are going less than 40 mph (64 km/h). If you come to a complete stop and it is hard to shift into 1 (First), put the shift lever in Neutral and let up on the clutch. Press the clutch pedal back down. Then shift into 1 (First).

2 (Second): Press the clutch pedal as you let up on the accelerator pedal and shift into 2 (Second). Then, slowly let up on the clutch pedal as you press the accelerator pedal.

3 (Third), 4 (Fourth), 5 (Fifth) and 6 (Sixth): Shift into 3 (Third), 4 (Fourth), 5 (Fifth) and 6 (Sixth) the same way you do for 2 (Second). Slowly let up on the clutch pedal as you press the accelerator pedal. To stop, let up on the accelerator pedal and press the brake pedal. Just before the vehicle stops, press the clutch pedal and the brake pedal, and shift to Neutral.

Neutral: Use this position when you start or idle the engine. The shift lever is in Neutral when it is centered in the shift pattern, not in any gear.

R (Reverse): To back up, press down the clutch pedal and shift into R (Reverse). Just apply pressure to get the lever past 5 (Fifth) and 6 (Sixth) into R (Reverse). Let up on the clutch pedal slowly while pressing the accelerator pedal.

The six-speed manual transmission has a feature that allows you to safely shift into R (Reverse) while the vehicle is rolling at less than 3 mph (5 km/h). You will be locked out if you try to shift into R (Reverse) while the vehicle is moving faster than 3 mph (5 km/h).

Shift Speeds (Manual Transmission)

Caution: If you skip a gear when you downshift, you could lose control of the vehicle. You could injure yourself or others. Do not shift down more than one gear at a time when you downshift.

This chart shows when to shift to the next higher gear for the best fuel economy.

Manual Transmission Recommended

Shift Speeds in mph (km/h)

Engine

Acceleration Shift Speed

1 to 2

2 to 3

3 to 4

4 to 5

5 to 6

All Engines

15 (24)

25 (40)

40 (64)

45 (72)

50 (80)

If the engine speed drops below 900 rpm, or if the engine is not running smoothly, you should downshift to the next lower gear. You may have to downshift two or more gears to keep the engine running smoothly or for good engine performance.

Notice: When shifting gears, do not move the shift lever around unnecessarily. This may damage the transmission. Shift directly into the next gear.

One to Four Shift Light (Manual Transmission)


Object Number: 1430320  Size: A1

When this light comes on, you can only shift from 1 (First) to 4 (Fourth) instead of 1 (First) to 2 (Second).

See One-to-Four Shift Light for more information.

Downshifting (Manual Transmission)

Do not downshift into the gear shown below at a speed greater than shown in the table:

1 (First)

50 mph (80 km/h)

2 (Second)

74 mph (119 km/h)

3 (Third)

101 mph (163 km/h)

4 (Fourth)

130 mph (209 km/h)

Notice: If you skip more than one gear when you downshift, or if you race the engine when you release the clutch pedal while downshifting, you could damage the engine, clutch, driveshaft or the transmission. Do not skip gears or race the engine when downshifting.

The six-speed transmission has a spring that centers the shift lever near 3 (Third) and 4 (Fourth). This spring helps you know which gear you are in when you are shifting. Be careful when shifting from 1 (First) to 2 (Second) or downshifting from 6 (Sixth) to 5 (Fifth). The spring will try to pull the shift lever toward 4 (Fourth) and 3 (Third). Make sure you move the lever into 2 (Second) or 5 (Fifth). If you let the shift lever move in the direction of the pulling, you may end up shifting from 1 (First) to 4 (Fourth) or from 6 (Sixth) to 3 (Third).
