If your vehicle is a Z06, do not downshift into a gear shown below at a speed greater than shown in the table: Parking Brake 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. The six-speed transmission has a spring that centers the gearshift 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 gearshift lever toward FOURTH (4) and THIRD (3). Make sure you move the lever into SECOND (2) or FIFTH (5). If you let the gearshift 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). To set the parking brake, hold the brake pedal down. Pull the parking brake lever up. If the ignition is on, the brake system warning light will come on. 2-30
