Preserving The Bodywork
Washing  
Wash  your  vehicle  regularly.  Always  wash
your vehicle in the shade using a mild car
wash  soap,  and  rinse  the  panels
completely with clear water.
If  insects,  tar,  or  other  similar  deposits
have  accumulated  on  your  vehicle,  use  a
specific detergent to remove.
Use  a  high quality cleaner wax to  remove
road film, stains and to protect your paint
finish.  Take  care  never  to  scratch  the
paint.
Avoid  using  abrasive  compounds  and
power buffing that may diminish the gloss
or thin out the paint finish.
Special Care
If  you  drive  on  salted  or  dusty  roads  or  if
you  drive  near  the  ocean,  hose  off  the
undercarriage at least once a month.
It is important that  the drain  holes  in  the
lower  edges  of  the  doors,  rocker  panels,
and trunk be kept clear and open.
If you detect any stone chips or scratches
in the  paint,  touch them up immediately.
The cost of such repairs is considered the
responsibility of the owner.
If  your  vehicle  is  damaged  due  to  a  colli-
sion  or  similar  cause  that  destroys  the
paint  and  protective  coating,  have  your
vehicle  repaired  as  soon  as  possible.  The
cost  of  such  repairs  is  considered  the
responsibility of the owner.
If  you  carry  special  cargo  such  as  chemi -
cals,  fertilizers,  de-icer  salt,  etc.,  be  sure
that such materials are well packaged and
sealed.
If a lot  of  driving is done on  gravel roads,
consider  mud  or  stone  shields  behind
each wheel.
Touch  up  the  scratches  as  soon  as
possible.  An  authorized  dealer  has  touch
up paint to match the color of your vehicle.
Some  parts  of  the  vehicle  may  be  painted
with  a  matte  paintwork  which  requires
special care for its preservation
 CAUTION!
Do  not  use  abrasive  or  strong  cleaning
materials such as steel wool or scouring
powder  that  will  scratch  metal  and
painted surfaces.
Use of power washers exceeding 1,200 psi
(8,274  kPa)  can  result  in  damage  or
removal of paint and decals.
 CAUTION!
Avoid  washing  with  rollers  and/or  brushes
in washing stations. Wash  the vehicle only
by hand using neutral pH detergents; dry it
with  a  wet  chamois  leather.  Abrasive
products  and/or  polishes  should  not  be
used  for  cleaning  the  car.  Bird  droppings
must  be  washed  off  immediately  and
thoroughly  as  the  acid  they  contain  is
particularly  aggressive.  Avoid  (if  at  all
possible)  parking  the  vehicle  under  trees;
remove  vegetable  resins  immediately  as,
when  dried,  it  may  only  be  possible  to
remove them with abrasive products and/or
polishes,  which  is  highly  inadvisable  as
they  could  alter  the  typical  opaqueness  of
the  paint.  Do  not  use  pure  windshield
washer  fluid  for  cleaning  the  front
windshield and rear window; dilute it  min.
50% with water. Only use pure windshield
washer fluid when strictly necessary due to
outside temperature conditions.

Appearance Care For Fabric Top Models 
To maintain the appearance of your vehicle's inte
-
rior trim and top, follow these precautions:
Avoid  leaving  your  vehicle  unattended
with  the  top  down,  as  exposure  to  sun  or
rain may damage interior trim.
Do  not  use  harsh  cleaners  or  bleaching
agents  on  top  material,  as  damage  may
result.
Do not allow any vinyl cleaner to run down
and dry on the paint, leaving a streak.
After  cleaning  your  vehicle's  fabric  top,
always  make  sure  it  is  completely  dry
before lowering.
Be  especially  careful  when  washing  the
windows  by  following  the  directions  for
“Care of Fabric Top Windows.”
Washing  –   Use  mild  soap  suds,  lukewarm
water, and a brush with soft bristles. If extra
cleaning  is  required,  use  a  mild  foaming
cleaner on the entire top, but support the top
from underneath.
Rinsing  –   Be  sure  to  remove  all  traces  of
cleaner  by  rinsing  the  top  thoroughly  with
clean  water.  Remember  to  allow  the  top  to
dry before lowering it. Some  parts  of  the  vehicle  may  be  painted
with  a  matte  paintwork  which  requires
special care for its preservation.
 CAUTION!
Failure to follow these cautions may cause
interior and exterior vehicle water damage,
stains  or  mildew  on  the  top  material  or
electrical components damage:
Avoid  high-pressure  car  washes  for  the
exterior  and  interior  of  the  vehicle,  as
they  can  damage  the  top  material  and
electrical  connectors.  Also,  increased
water  pressure  may  force  past  the
weather strips.
It is recommended that the top be free of
water  prior  to  opening  it.  Operating  the
top, opening a door or lowering a window
while  the  top  is  wet  may  allow  water  to
drip into the vehicle’s interior.
Use  care  when  washing  the  vehicle,
water  pressure  directed  at  the  weather
strip  seals  may  cause water  to  leak  into
the vehicle’s interior.
Careless  handling  and  storage  of  the
removable  roof  panels  may  damage  the
seals,  causing  water  to  leak  into  the
vehicle’s interior.
The  front  panel(s)  must  be  positioned
properly  to  ensure  sealing.  Improper
installation can cause water to leak into
the vehicle’s interior.
 CAUTION!
Avoid  washing  with  rollers  and/or
brushes  in  washing  stations.  Wash  the
vehicle  only  by  hand  using  neutral  pH
detergents;  dry  it  with  a  wet  chamois
leather.  Abrasive  products  and/or
polishes should not be used for cleaning
the car. Bird droppings must be washed
off  immediately  and  thoroughly  as  the
acid  they  contain  is  particularly  aggres-
sive.
Avoid  (if  at  all  possible)  parking  the
vehicle  under  trees;  remove  vegetable
resins  immediately  as,  when  dried,  it
may  only  be  possible  to  remove  them
with  abrasive  products  and/or  polishes,
which is highly inadvisable as they could
alter the typical opaqueness of the paint.

Care Of Fabric Top Windows
Your  vehicle's  fabric  top  has  pliable  plastic
windows  which  can  be  scratched  unless
special  care  is  taken  by  following  these
directions:
Never  use  a  dry  cloth  to  remove  dust.
Instead, use  a  microfiber  towel  or  soft
cotton  cloth  moistened  with  cold  or  warm,
clean  water,  and  wipe  across  the  window,
not up and down.  It removes fine scratches
to  improve  visibility  and  provides  UV
protection to help prevent yellowing.
When  washing,  never  use  hot  water   or
anything stronger than a mild soap. Never
use  solvents  such  as  alcohol  or  harsh
cleaning agents.
Always  rinse  thoroughly  with  cold  water,
then  wipe  with  a  soft  and  slightly  moist,
clean cloth.
When  removing  frost,  snow  or  ice,  never
use  a  scraper  or  de-icing  chemicals.   Use
warm  water  only  if  you  must  clean  the
window quickly.
Debris (sand, mud/dirt, dust, or salt) from
off-road  driving  will  have  an  impact  on
plastic  retainer  operation.  Even  normal
on-road  driving  and  vehicle  washing  will
eventually impact window  plastic  retainer
operation. To maintain  ease of  use of  the
window  plastic  retainers,  each  window
plastic  retainer  should  be  cleaned  and
lubricated  regularly.  Clean  them  with  a
mild  soap  solution  and  a  small  brush.
Cleaning  products  are  available  through
an authorized dealer.
Never  paste  stickers,  gummed  labels  or
any  tape  to  the  windows.  Adhesives  are
hard  to  remove  and  may  damage  the
windows.
INTERIORS 
Seats And Fabric Parts
Use a specific product to clean fabric uphol -
stery and carpeting.
Seat Belt Maintenance
Do  not  bleach,  dye  or  clean  the  belts  with
chemical solvents or  abrasive cleaners. This
will weaken the fabric. Sun damage can also
weaken the fabric.
If  the  belts  need  cleaning,  use  a  mild  soap
solution  or  lukewarm  water.  Do  not  remove
the belts from the vehicle to wash them. Dry
with a soft cloth.
Replace  the  belts  if  they  appear  frayed  or
worn or if the buckles do not work properly.
Do not use pure windshield washer fluid
for  cleaning  the  front  windshield  and
rear  window;  dilute  it  min.  50%  with
water.  Only  use  pure  windshield  washer
fluid  when  strictly  necessary  due  to
outside temperature conditions.
 CAUTION! (Continued)
 WARNING!
Do  not  use  volatile  solvents  for  cleaning
purposes. Many are potentially flammable,
and if used in closed areas they may cause
respiratory harm.

Plastic And Coated Parts
Use a  specific product  to  clean  vinyl uphol-
stery.
Cleaning Plastic Instrument Cluster Lenses 
The lenses in front of the instruments in this
vehicle  are  molded  in  clear  plastic.  When
cleaning  the  lenses,  care  must  be  taken  to
avoid scratching the plastic.
1. Clean with a  wet soft  cloth.  A  mild soap solution  may  be  used,  but  do  not  use
high  alcohol  content  or  abrasive
cleaners. If soap is used, wipe clean with
a clean damp cloth.
2. Dry with a soft cloth.
Leather Parts
Your  leather  upholstery  can  be  best
preserved  by  regular  cleaning  with  a  damp
soft cloth.  Small  particles  of dirt  can  act as
an  abrasive  and  damage  the  leather  uphol -
stery and should be removed promptly with a
damp  cloth.  Care  should  be  taken  to  avoid
soaking  your  leather  upholstery  with  any
liquid.  Please  do  not  use  polishes,  oils,
cleaning  fluids,  solvents,  detergents,  or
ammonia-based  cleaners  to  clean  your
leather  upholstery.  Application  of  a  leather
conditioner  is  not  required  to  maintain  the
original condition. NOTE:
If  equipped  with  light  colored  leather,  it
tends to show any foreign material, dirt, and
fabric  dye  transfer  more  so  than  darker
colors.  The  leather  is  designed  for  easy
cleaning.
Glass Surfaces 
All  glass  surfaces  should  be  cleaned  on  a
regular  basis  with  any  commercial  house
-
hold-type  glass  cleaner.  Never  use  an  abra -
sive type cleaner. Use caution when cleaning
the  inside  rear  window  equipped  with  elec -
tric  defrosters  or  windows  equipped  with
radio antennas. Do not use scrapers or other
sharp  instruments  that  may  scratch  the
elements.
When  cleaning  the  rear  view  mirror,  spray
cleaner  on  the  towel  or  cloth  that  you  are
using.  Do  not  spray  cleaner  directly  on  the
mirror.
 WARNING!
A  frayed  or  torn  belt  could  rip  apart  in  a
collision and leave  you with no protection.
Inspect  the  belt  system  periodically,
checking  for  cuts,  frays,  or  loose  parts.
Damaged  parts  must  be  replaced
immediately. Do not disassemble or modify
the  system.  Seat  belt  assemblies  must  be
replaced after a collision if they have been
damaged  (i.e.,  bent  retractor,  torn
webbing, etc.).
 CAUTION!
Direct  contact  of  air  fresheners,  insect
repellents,  suntan  lotions,  or  hand  sani -
tizers  to the plastic, painted, or decorated
surfaces  of  the  interior  may  cause  perma -
nent damage. Wipe away immediately.
Damage  caused  by  these  type  of  prod -
ucts  may  not  be  covered  by  your  New
Vehicle Limited Warranty.
 CAUTION!
Do not use Alcohol and Alcohol-based and/
or  Ketone  based  cleaning  products  to
clean leather upholstery, as damage to the
upholstery may result.
