Ve hicles with rear wheel drive
Only use the middle rod and the pump le verrod
with the largest diame terfo rth e jack as a lug
wrench extension. Only inse rtthe middle rod on
th e lug wrench, and alw ays as far as it will go.
Otherwise, thero ds could bend and deform so
much that they can no longer be used as pu mp

Ve hicles with Super Single tires: if you mount the
spare wheel tothere ar axle, do not exceed the
maximum speed of 34 mph (55 km/h) and the
maximum dis tance of 62 miles (100 km). Other‐
wise, the transmission could be damaged due to
th e dif fere nt rotational speeds of the wheels. #
