WARNING
Improperly lifting your vehicle with a workshop hoist or a floor jack can cause the vehicle to fall off and cause serious personal injury.
x Always read and heed the operating instructions from the floor jack manufacturer and legal regulations if necessary before using the floor jack to lift the vehicle.
x Never let anyone stay in the vehicle when it is being lifted or when it is off the ground.
x Always lift your vehicle only at the designated lift points shown in the illustrations
⇒ fig. 188 and ⇒ fig. 189. Not using the designated lift points can cause the vehicle to fall off the floor jack when heavy parts such as the engine or transmission are removed.
x Always make sure that the vehicle's lift points lie as flat as possible and centered on the carrier plates of the floor jack.
x Never start the engine when you have raised the vehicle on the floor jack. The engine vibrations and vehicle movements could knock the vehicle off the floor jack.
x If you must work under a vehicle raised on a floor jack, always make sure that the vehicle is safely supported on safety stands intended for that purpose that are strong enough to support the weight of the vehicle.
x Never use the floor jack as a ladder or step ladder.
x Always make sure that the weight of the vehicle is not heavier than the lifting capacity of the floor jack and safety stands being used.
NOTICE
x To help prevent serious vehicle damage, never lift the vehicle by the engine oil pan, transmission housing, or by the front or rear axles or suspension.
x To help prevent damage to the underbody or chassis, always insert a rubber pad between the hoist and the lifting points. In addition make sure the lifting arms have enough clearance.
x The lifting arms should not touch side sills or other parts of the vehicle.
