 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.

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.

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.

Jack Usage Precautions
To  complete  the  Use  and  Maintenance
Handbook  to  which  this  supplement  is
attached,  given  below are some instructions
on the proper use of the jack.MaintenanceMake sure grime does not build up on the
“worm screw.”
Keep the “worm screw” lubricated.
Never modify the jack.
Conditions Of Non-Use:
Temperatures below −40°C.
On sandy or muddy ground.
On uneven ground.
On steep roads.
In  extreme  weather  conditions:  thunder -
storms,  typhoons,  hurricanes,  blizzards,
storms, etc.
NOTE:
The jack requires no adjustment.
The  jack  cannot  be  repaired,  and  in  the
event  of  a  fault,  it  must  be  replaced  by
another genuine one.
No tool other than its cranking device may
be fitted on the jack.
 WARNING!
When  using  the  crank,  make  sure  it  turns
freely  without  the  risk  of  scraping  hands
against the ground.
Even  the  moving  parts  of  the  jack,  the
“worm  screw”  and  joints  can  cause
injuries:  avoid contact with  them. Clean  it
thoroughly if dirtied with grease.
 CAUTION!
The  jack  is  a  tool  designed  exclusively  for
changing a wheel, in case of a puncture or
damage to a tire of the vehicle on which it
is fitted or on vehicles of the same model.
Any other use, e.g. to jack up other vehicle
models  or  different  things,  is  strictly
prohibited.  Never  use  it  to  carry  out
maintenance  or  repairs  under  the  vehicle
or  to  change  summer/winter  wheels  and
vice  versa.  Never  go  under  the  raised
vehicle.  If  any  work  under  the  vehicle  is
necessary,  contact  an  authorized  dealer.
Incorrect placing of the jack can cause the
vehicle to drop: use it only in the positions
indicated.  Do  not  use  the  jack  for  loads
higher  than  that  specified  on  the  label.
Never start the  engine with  vehicle raised.
If  the  vehicle  is  raised  more  than
necessary,  everything  can  become  more
unstable,  with  the  risk  of  the  vehicle
dropping  violently.  Therefore  raise  the
vehicle  only  as  much  as  necessary  for  the
wheel/spare.

NOTE:
Wheel  Valve  Stem must be replaced  as  well
when  installing  new  tires  due  to  wear  and
tear in existing tires.
Keep  dismounted  tires  in  a  cool,  dry  place
with  as  little  exposure  to  light  as  possible.
Protect  tires  from  contact  with  oil,  grease,
and gasoline.
Replacement Tires 
The  tires  on  your  new  vehicle  provide  a
balance of many characteristics. They should
be  inspected  regularly  for  wear  and  correct
cold  tire  inflation  pressures.  The  manufac-
turer strongly recommends that you use tires
equivalent  to  the  originals  in  size,  quality
and  performance  when  replacement  is
needed.  Refer  to  the  paragraph  on  “Tread
Wear Indicators” in this section. Refer to the
Tire and  Loading Information placard  or  the
Vehicle Certification Label for the size desig -
nation  of  your  tire.  The  Load  Index  and
Speed  Symbol for  your tire  will  be found on
the original equipment tire sidewall.
It  is  recommended  to  replace  the  two  front
tires or two rear tires as a pair. Replacing just
one  tire  can  seriously  affect  your  vehicle’s handling.  If you  ever replace  a wheel, make
sure  that  the  wheel’s  specifications  match
those of the original wheels.
It is recommended you contact an authorized
tire dealer or original equipment dealer with
any questions you may have on tire specifica
-
tions or capability. Failure to use equivalent
replacement  tires  may  adversely  affect  the
safety, handling, and ride of your vehicle. WARNING!
Do not use a tire, wheel size, load rating,
or speed rating other than that specified
for  your  vehicle.  Some  combinations  of
unapproved tires and wheels may change
suspension dimensions and performance
characteristics,  resulting  in  changes  to
steering,  handling,  and  braking  of  your
vehicle.  This  can  cause  unpredictable
handling  and  stress  to  steering  and
suspension components.  You could lose
control  and  have  a  collision  resulting  in
serious injury or death. Use only the tire
and  wheel  sizes  with  load  ratings
approved for your vehicle.
Never use a tire with a smaller load index
or  capacity,  other  than  what  was  origi -
nally  equipped  on your  vehicle.  Using  a
tire with a smaller load index could result
in tire overloading and failure. You could
lose control and have a collision.
Failure  to  equip  your  vehicle  with  tires
having  adequate  speed  capability  can
result  in  sudden  tire  failure  and  loss  of
vehicle control.
 CAUTION!
Replacing  original  tires  with  tires  of  a
different  size  may  result  in  false
speedometer and odometer readings.
