& WARN ING (continued )
• The engine compartment of any motor vehicle is a potentially
hazardous area . Never reach into the area around or touch the
radiator fan . It is temperature controlled and can sw itch on
suddenly -even when the engine is off and the ignition key has
been removed . The radiator fan switches on automatically when
the coolant reaches a certain temperature and will continue to run until the coolant temperature drops .
• Always remove the ignition key before anyone gets under the
vehi cle .
• Always support your vehicle with safety stands if it is neces ­
sary to work underneath the vehicle . The jack suppl ied with the
vehicle is not adequate for this purpose and could collapse causing serious personal injury .
• If you must work underneath the vehicle with the wheels on
the ground, always make sure the veh icle is on level ground , that
the wheels are always securely blocked and that the engine
cannot be sta rted .
• Always make sure the transmission selector lever (automatic
transmission) is in "P " (Park position ) or Neutral (manual transm is­
sion) and the park brake is firmly applied.
