1. Turn the ignition key to the "OFF" position.
2. Place the gear shift lever in the "N" position on a manual transmission (in the "P" position on an automatic transmission).
3. Tighten the parking brake lever.
4. Check the alternator drive belt for damage. If damage is found, the belt must be replaced. Main damages to the belt:
- Wear of the edges of the V-shaped ribs of belt B and exposure of the cord in the grooves of belt C; on new belts the ribs have a trapezoidal shape A (figure 1.2);
