Anti-Lock Brake System Warning Light The orange anti-lock brake system warning light is located near the top right corner of the instrument cluster With anti-lock, this light will go on when you start your engine and may stay on for several seconds. That's normal. If the light doesn't come on, have it fixed so it will be ready to warn you if there is a problem. If the light stays on, or comes on when you're driving,your vehicle needs service. If the regular brake system warning light isn't on, you still have brakes, but you don't have anti-lock brakes. If the regular brake system warning light is also on, you don't have anti-lock brakes and there's a problem with your regular brakes. See "Brake System Warning Light" earlier in this part. Water in Fuel Light The red Water in Fuel light, if you have one, is located near the middle right edge of the instrument cluster, just below the turn signal and lane change indicator. This light will come on to warn you if there is water in the diesel fuel system. For more information on how this light works, see "Diesel Fuel Requirements and Fuel System" in the Index. 2-68
