DANGER
Engines produce carbon monoxide which
is odorless, causes slower reaction time,
and can lead to serious injury. When the
engine is operating, keep service areas
WELL VENTILATED or attach the vehicle
exhaust system to the shop exhaust
removal system.
Set the parking brake and block the
wheels before testing or repairing the
vehicle. It is especially important to block
the wheels on front-wheel drive vehicles;
the parking brake does not hold the drive
wheels.
Wear an eye shield when testing or
repairing vehicles.
