Checking Oil Level
To  assure  proper  engine  lubrication,  the
engine oil must be maintained at the correct
level. Check the oil level at regular intervals,
such  as  every  fuel  stop.  The  best  time  to
check  the  engine  oil  level  is  about  five
minutes  after  a  fully  warmed  up  engine  is
shut off.
Checking the oil while the vehicle is on level
ground  will  improve  the  accuracy  of  the  oil
level readings.
There are three possible dipstick types,
Crosshatched zone.
Crosshatched zone marked SAFE.
Crosshatched  zone  marked  with  MIN  at
the  low  end  of  the  range  and  MAX  at  the
high end of the range.
Crosshatched  zone  marked  with  dimples
at the MIN and the MAX ends of the range.
NOTE:
Always  maintain  the  oil  level  within  the
crosshatch markings on the dipstick.
Adding  1  quart  (1.0  liters)  of  oil  when  the
reading  is  at  the  low  end  of  the  dipstick
range  will  raise the  oil  level to the high  end
of the range marking.
Adding Washer Fluid 
The  fluid  reservoir  is  located  in  the  front  of
the  engine  compartment.  Be  sure  to  check
the fluid level in the reservoir at regular inter -
vals. Fill the reservoir with windshield washer
solvent (not  radiator antifreeze) and  operate
the system for a few seconds to flush out the
residual washer fluid.
When  refilling  the  washer  fluid  reservoir,
take some washer fluid, apply it to a cloth or
towel, and wipe clean the wiper blades; this
will help blade performance.
 WARNING!
Never smoke while working in the engine
compartment:  gas  and  inflammable
vapors  may  be  present,  with  the  risk  of
fire.
Be  very  careful  when  working  in  the
engine compartment when the engine is
hot: you may get burned. Do not get too
close  to  the  radiator  cooling  fan:  the
electric  fan  may  start;  danger  of  injury.
Scarves,  ties  and  other  loose  clothing
might be pulled by moving parts.
 CAUTION!
Be  careful  not  to  confuse  the  various
types of fluids while topping up: they are
not compatible with each other! Topping
up  with  an  unsuitable  fluid  could
severely damage your car.
The oil level must never exceed the MAX
mark.
Always  top  up  using  engine  oil  of  the
same  specifications  as  that  already  in
the engine.
If the engine oil is being topped up, wait
for the engine  to cool  down  before  loos-
ening the filler cap, particularly for vehi -
cles  with  aluminium  cap  (if  equipped).
WARNING: risk of burns!
Overfilling  or  underfilling  the  crankcase
will cause aeration or loss of oil pressure.
This could damage your engine.
 CAUTION! (Continued)

To  prevent  freeze-up  of  your  windshield
washer system in cold weather, select a solu-
tion  or  mixture  that  meets  or  exceeds  the
temperature  range  of  your  climate.  This
rating  information  can  be  found  on  most
washer fluid containers.
Maintenance-Free Battery 
Your  vehicle  is  equipped  with  a  mainte -
nance-free  battery.  You  will  never  have  to
add  water,  nor  is  periodic  maintenance
required.
 WARNING!
Commercially  available  windshield  washer
solvents  are  flammable.  They  could  ignite
and  burn  you.  Care  must  be  exercised
when  filling  or  working  around  the  washer
solution.
 CAUTION!
Do  not  travel  with  the  windshield  washer
fluid  reservoir  empty:  the  windshield
washer is essential for improving visibility.
 WARNING!
Using  the  battery  with  low  fluid  will
irreparably  damage the  battery  and may
cause an explosion.
When  performing  any  operation  on  the
battery  or  near  it,  always  protect  your
eyes with special goggles.
Batteries  contain  substances  which  are
very dangerous for  the environment. For
battery  replacement,  contact  an  autho-
rized dealership.
Battery fluid  is  a  corrosive  acid solution
and  can  burn  or  even  blind  you.  Do  not
allow  battery  fluid  to  contact  your  eyes,
skin,  or  clothing.  Do  not  lean  over  a
battery  when  attaching  clamps.  If  acid
splashes  in  eyes  or  on  skin,  flush  the
area  immediately  with  large  amounts  of
water.  Refer  to  “Jump  Starting  Proce-
dure”  in  “In  Case  Of  Emergency”  for
further information.
Battery  gas  is  flammable  and  explosive.
Keep  flame  or  sparks  away  from  the
battery.  Do  not  use  a  booster  battery  or
any other booster source  with an output
greater than 12 Volts. Do not allow cable
clamps to touch each other.
Battery  posts,  terminals,  and  related
accessories  contain  lead  and  lead
compounds. Wash hands after handling.
 CAUTION!
It is essential when replacing the cables
on  the  battery  that  the  positive  cable  is
attached  to  the  positive  post  and  the
negative  cable  is  attached  to  the  nega-
tive post. Battery posts are marked posi -
tive  (+)  and  negative  (-)  and  are
identified  on  the  battery  case.  Cable
clamps  should  be  tight  on  the  terminal
posts and free of corrosion.
If  a  “fast  charger”  is  used  while  the
battery is in the vehicle, disconnect both
vehicle battery cables before connecting
the  charger to  the battery.  Do  not  use  a
“fast  charger”  to  provide  starting
voltage.

DEALER SERVICE 
An  authorized  dealer  has  the  qualified
service  personnel,  special  tools,  and  equip-
ment  to  perform  all service operations  in an
expert  manner.  Service  Manuals  are  avail -
able which include detailed service informa -
tion  for  your  vehicle.  Refer  to  these  Service
Manuals  before  attempting  any  procedure
yourself. NOTE:
Intentional tampering with emissions control
systems  may  void  your  warranty  and  could
result  in  civil  penalties  being  assessed
against you.
Air Conditioner Maintenance  
For  best  possible  performance,  your  air
conditioner should be checked and serviced
by  an  authorized  dealer  at  the  start  of  each
warm  season.  This  service  should  include
cleaning of the condenser fins and a perfor
-
mance test. Drive belt tension should also be
checked at this time.
 CAUTION!
Cleaning  the  engine  compartment  with  a
high pressure washer is not recommended.
Precautions  have  been  taken  to  safeguard
all  parts  and  connections  however,  the
pressures  generated  by  these  machines  is
such  that  complete  protection  against
water ingress cannot be guaranteed.
 WARNING!
You  can  be  badly  injured  working  on  or
around  a  motor  vehicle.  Only  do  service
work  for  which  you  have  the  knowledge
and the proper equipment. If you have any
doubt  about  your  ability  to  perform  a
service  job,  take  your  vehicle  to  a
competent mechanic.
 WARNING!
Use  only  refrigerants  and  compressor
lubricants approved by the manufacturer
for  your  air  conditioning  system.  Some
unapproved  refrigerants  are  flammable
and  can  explode,  injuring  you.  Other
unapproved  refrigerants  or  lubricants
can  cause  the  system  to  fail,  requiring
costly  repairs.  Refer  to  Warranty  Infor -
mation  Book,  located  in  your  owner’s
information  kit,  for  further  warranty
information.
The  air  conditioning  system  contains
refrigerant under high pressure. To avoid
risk  of  personal  injury  or  damage  to  the
system,  adding  refrigerant  or  any  repair
requiring  lines  to  be  disconnected
should be done by an experienced tech -
nician.
 CAUTION!
Do  not  use  chemical  flushes  in  your  air
conditioning  system  as  the  chemicals  can
damage your air conditioning components.
Such  damage  is  not  covered  by  the  New
Vehicle Limited Warranty.

See an authorized dealer for service.
Wiper Blades 
Clean  the  rubber  edges  of  the  wiper  blades
and the windshield and rear window periodi-
cally with  a  sponge  or  soft  cloth and a  mild
nonabrasive  cleaner.  This  will  remove  accu -
mulations  of  salt,  waxes,  or  road  film,  and
help reduce streaking and smearing.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use  washer  fluid  when using
the  wipers  to  remove  salt  or  dirt  from  a  dry
windshield or rear window.
Avoid using the wiper blades to remove frost
or  ice  from  the  windshield  or  rear  window.
Make  sure  that  they  are  not  frozen  to  the
glass  before  turning  them  on  to  avoid
damaging  the  blade.  Keep  the  wiper  blade
out of contact with petroleum products such
as engine oil, gasoline, etc.
NOTE:
Life  expectancy  of  wiper  blades  varies
depending  on  geographical  area  and
frequency  of  use.  Poor  performance  of
blades  may  be  present  with  chattering, marks,  water  lines  or  wet  spots.  If  any  of
these conditions are present, clean the wiper
blades or replace as necessary.
Exhaust System 
The best protection against carbon monoxide
entry  into  the  vehicle  body  is  a  properly
maintained engine exhaust system.
If  you  notice  a  change  in  the  sound  of  the
exhaust system; or if the exhaust fumes can
be  detected  inside  the  vehicle;  or  when  the
underside or rear of the vehicle is damaged;
have  an  authorized  technician  inspect  the
complete exhaust system and adjacent body
areas  for  broken,  damaged,  deteriorated,  or
mispositioned  parts.  Open  seams  or  loose
connections  could  permit  exhaust  fumes  to
seep  into  the  passenger  compartment.  In
addition, have the exhaust system inspected
each time the vehicle is raised for lubrication
or oil change. Replace as required.
 WARNING!
Exhaust  gases  can  injure  or  kill.  They
contain carbon monoxide (CO), which is
colorless  and  odorless.  Breathing  it  can
make  you  unconscious  and  can  eventu
-
ally  poison  you.  To  avoid  breathing  CO,
refer  to  “Safety  Tips”  in  “Safety”  for
further information.
A  hot  exhaust  system  can  start  a  fire  if
you  park  over  materials  that  can  burn.
Such materials might be  grass or leaves
coming  into  contact  with  your  exhaust
system.  Do  not  park  or  operate  your
vehicle  in  areas  where  your  exhaust
system  can  contact  anything  that  can
burn.
 CAUTION!
The  catalytic  converter  requires  the  use
of  unleaded  fuel  only.  Leaded  gasoline
will destroy the effectiveness of the cata-
lyst  as  an  emissions  control  device  and
may  seriously  reduce  engine  perfor -
mance and cause serious damage to the
engine.
