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

Here is how to operate your transmission:

FIRST (1): Press the clutch pedal and shift into FIRST (1). Then slowly let up on the clutch pedal as you press the accelerator pedal. You can shift into FIRST (1) 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 FIRST (1), put the shift lever in NEUTRAL and let up on the clutch. Press the clutch pedal back down. Then shift into FIRST (1).

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

THIRD (3), FOURTH (4), FIFTH (5) and SIXTH (6): Shift into THIRD (3), FOURTH (4), FIFTH  (5) and SIXTH (6) the same way you do for SECOND (2). 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 your engine. Your shift lever is in NEUTRAL when it is centered in the shift pattern, not in any gear.

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

Your six-speed manual transmission has a feature that allows you to safely shift into REVERSE (R) while the vehicle is rolling at less than 3 mph (5 km/h). You will be locked out if you try to shift into REVERSE (R) while your vehicle is moving faster than 3 mph (5 km/h). If you have turned your ignition off the shifter must be shifted to REVERSE (R), enabling the vehicle to be turned off. Otherwise, the vehicle will remain in accessory mode.

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 your 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 FIRST (1) to FOURTH (4) instead of FIRST (1) to SECOND (2).

You must complete the shift into FOURTH (4) to turn off this feature. This helps you get the best possible fuel economy.

After shifting to FOURTH (4), you may downshift to a lower gear if you prefer.

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.

This light will come on when:

    • The engine coolant temperature is higher than 169°F (76°C),
    • you are going 15 to 19 mph (24 to 31 km/h) and
    • you are 21 percent throttle or less.

Downshifting (Manual Transmission)

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

FIRST (1)

50 mph (80 km/h)

SECOND  (2)

74 mph (119 km/h)

THIRD (3)

101 mph (163 km/h)

FOURTH (4)

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 THIRD (3) and FOURTH (4). This spring helps you know which gear you are in when you are shifting. Be careful when shifting from FIRST (1) to SECOND (2) or downshifting from SIXTH (6) to FIFTH (5). The spring will try to pull the shift lever toward FOURTH (4) and THIRD (3). Make sure you move the lever into SECOND (2) or FIFTH (5). If you let the shift lever move in the direction of the pulling, you may end up shifting from FIRST (1) to FOURTH (4) or from SIXTH (6) to THIRD (3).
