&, WARNING (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 switch 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 .

sary to work underneath the vehicle . The jack suppl ied with the

the ground , always make sure the vehicle is on level ground , that
the wheels are always securely blocked and that the engine
cannot be started .
