Cavity Cartridge Fuse Micro Fuse Description
 CAUTION!
When  installing  the  power  distribution
center  cover,  it  is  important  to  ensure
the cover is properly positioned and fully
latched. Failure to do so may allow water
to get into the power distribution center
and  possibly  result  in  an  electrical
system failure.
When  replacing  a  blown  fuse,  it  is
important  to  use  only  a  fuse  having  the
correct  amperage  rating.  The  use  of  a
fuse  with  a  rating  other  than  indicated
may  result  in  a  dangerous  electrical
system overload. If a properly rated fuse
continues to blow, it indicates a problem
in the circuit that must be corrected.
 WARNING!
Do  not  attempt  to  change  a  tire  on  the
side  of  the  vehicle  close  to  moving
traffic.  Pull  far  enough  off  the  road  to
avoid the danger of being hit when oper-
ating the jack or changing the wheel.
Being  under  a  jacked-up  vehicle  is
dangerous. The vehicle could slip off the
jack  and  fall  on  you.  You  could  be
crushed. Never put any part of your body
under  a  vehicle  that is  on  a jack.  If  you
need to get  under  a  raised  vehicle, take
it  to  a  service  center  where  it  can  be
raised on a lift.
Never  start  or  run  the  engine  while  the
vehicle is on a jack.
The jack is designed to be used as a tool
for  changing  tires only.  The  jack  should
not be used to lift the vehicle for service
purposes.  The  vehicle  should  be  jacked
on a firm level surface only. Avoid ice or
slippery areas.
 WARNING! (Continued)

3. Remove the lug nuts with the lug wrench turning  them  counterclockwise.  If
equipped,  remove  the  locking  lug  nut
with  the  lock  key  (located  in  the  glove
box) turning it counterclockwise.
Removing The Spare Tire
Preparations For Jacking 
1. Park on a firm, level surface. Avoid ice orslippery areas.
2. Turn on the Hazard Warning flasher.
3. Apply the parking brake.
4. Shift  the  automatic  transmission  into PARK (P), or a manual transmission into
REVERSE (R).
5. Turn the ignition OFF. 6. Block both the front and rear of the wheel
diagonally opposite  the jacking  position.
For  example,  if  the  right  front  wheel  is
being changed, block the left rear wheel.
Wheel Blocked
NOTE:
Passengers should not remain in the vehicle
when the vehicle is being lifted or raised.
 WARNING!
Do not attempt to change a tire on the side
of  the  vehicle  close  to moving  traffic. Pull
far  enough  off  the  road  to  avoid  being  hit
when  operating  the  jack  or  changing  the
wheel.

Jacking Instructions  
Jack Warning Label1. Remove  the  spare  tire,  jack  and  tools
from the stored location.
2. Loosen (but do not remove) the wheel lug nuts by turning them to the left one turn
while the wheel is still on the ground.
3. Assemble  the  jack  and  jacking  tools. Connect  the  jack  handle  driver  to  the
extension, then to the lug wrench.
Assembled Jack And Tools
 WARNING!
Carefully  follow  these  tire  changing
warnings to help prevent personal injury or
damage to your vehicle:
Always  park  on  a  firm,  level  surface  as
far  from  the  edge  of  the  roadway  as
possible before raising the vehicle.
Turn on the Hazard Warning flashers.
Block  the  wheel  diagonally  opposite the
wheel to be raised.
Apply the parking brake firmly and shift
an automatic transmission to PARK.
Never  start  or  run  the  engine  with  the
vehicle on a jack.
Do not let anyone sit in the vehicle when
it is on a jack.
Do  not  get  under  the  vehicle  when  it  is
on  a  jack.  If  you  need  to  get  under  a
raised vehicle, take it to a service center
where it can be raised on a lift.
Only  use  the  jack  in  the  positions  indi -
cated and for lifting this vehicle during a
tire change.
If  working  on  or  near  a  roadway,  be
extremely careful of motor traffic.
To  assure  that  spare  tires,  flat  or
inflated,  are  securely  stowed,  spares
must  be  stowed  with  the  valve  stem
facing the ground.
 WARNING! (Continued) CAUTION!
Do  not  attempt  to  raise  the  vehicle  by
jacking  on  locations  other  than  those
indicated.

4. Operate the jack from the front or the rearof  the  vehicle.  Place  the  jack  under  the
axle  tube,  as  shown.  Do  not  raise  the
vehicle  until  you  are  sure  the  jack  is  fully
engaged.

Rear Jacking Location
5. Raise  the  vehicle  by  turning  the  jack screw  clockwise.  Raise  the  vehicle  only
until  the  tire  just  clears  the  surface  and
enough  clearance  is  obtained  to  install
the spare tire. Minimum tire lift provides
maximum stability. 6. Remove the lug nuts and wheel.
7. Mount the spare tire on the axle.
8. Install the lug nuts with the cone-shaped
end toward the wheel. Lightly tighten the
lug nuts clockwise.
9. Lower  the  vehicle  by  turning  the  jack screw  to  the  counterclockwise,  and
remove the jack. WARNING!
Raising  the  vehicle  higher  than  necessary
can  make  the  vehicle  less  stable.  It  could
slip off the jack and hurt someone near it.
Raise  the  vehicle  only  enough  to  remove
the tire.
 WARNING!
To  avoid  the  risk  of  forcing  the  vehicle  off
the  jack,  do  not  tighten  the  wheel  nuts
fully  until  the  vehicle  has  been  lowered.
Failure to follow this warning may result in
serious injury.
