¢(D.

258 What do I do no w?
• Use the hexagonal socket in the screwdriver
hand le to screw in and tighten all wheel
bolts
slightly .
• Remove the alignment pin and insert and
t ighten the remaining wheel bolt slightly
Like the rest .
• Turn the jack handle counter-clockw ise to
lower the vehicle unt il the jack is fully re­
leased .
• Use the whee l bolt wrench to t ighten al l
wheel bolts firmly¢
page 255 . Tighten
them
crosswise, from one bolt to the (ap­
proximate ly) opposite one, to keep the
whee l centered.
@ Note
When removing or installing the wheel,
the rim could hit the brake rotor and dam­
age the rotor. Work carefully and have a
second person help you.
@ Tips
Never use the hexagonal socket in the han­
dle of the screwdriver to loosen or tighten
the wheel bolts .
- Pull the reversible b lade from the screw­
driver before you use the hexagonal

- When mounting tires with
unid irectional
t re ad design
make sure the tread pat­
tern is pointed the right way
~ page 258.
- The wheel bolts should be clean and easy
to turn . Check for d irt and corrosion on
the mat ing surfaces of both the whee l

s ur faces before remo unt ing the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction .
Using a sp are t ire w ith a tre ad pattern
intended for use in a specific direction
When using a spare t ire with a tread patter n
intended for use in a spec ific d irection , please
note the following :
- The direct ion of rotation is marked by an ar­
row on the side of the ti re .
- If the spare tire has to be installed in the in­
correct direct ion, use the spare tire only
temporarily s ince the tire will not be able to
achieve its optim um performance cha racter­
is tic s wit h regard to aquap la ni ng, no ise and
wear .
- We recommend that you pay part icu la r at­
t en tion to th is fact d uring wet wea ther and
