5. For a rear tire, place the jack in the slot on
the rear tie-down bracket, just forward of
the rear tire (as indicated by the triangular
lift point symbol on the sill molding). Do not
raise the vehicle until you are sure the jack
is fully engaged.
CAUTION!
Do NOT raise the vehicle by the body side sill
molding. Be sure the jack is placed in the
proper engagement location on the inside of
the panel. Damage of the vehicle may occur if
the procedure is not properly followed.
NOTE:
The rear lifting point location is the same for all
trim levels.

clockwise. Raise the vehicle only until the
tire just clears the surface and enough

tire. Minimum tire lift provides maximum
stability.
