Never drive until the tank is completely emp­
ty. The irregular supply of fuel that results
from that can cause engine misfires . Uncom­
busted fuel will then enter the exhaust sys­
tem. This can cause overheating and damage
to the catalytic converter .

- Read and follow the warnings in
¢ page 235, Working in the engine com­
partment
before opening the hood and
checking the brake fluid level.
- If the brake system indicator light does not
turn off or it turns on while driving, the
