Downloaded from www.Manualslib.com manuals search engine To signal a lane  change,  just  raise  or  lower  the  lever  until  the  green  ar\
row 
starts  to 
flash. Hold it  there  until  you  complete  your  lane  change.  The  lever 
will return  by  itself  when  you  release  it. 
As you  signal  a  turn  or  a  lane chi' -- if the  arrows  don’t  flash  but  just  stay 
on,  a  signal  bulb  may  be  burned 
OUT and other  drivers  won’t  see  your  turn 
signal. 
(If your  vehicle  has  the  digital  instrument  cluster,  the  turn  signa\
l  arrows  will 
flash  at  a  faster  rate 
if a  signal  bulb  is  burned  out.) 
If a  bulb  is  burned  out,  replace it to  help  avoid  an  accident. If the  green 
arrows  don’t  go  on  at  all when  you  signal  a  turn,  check  the  fuse  (see 
“Fuses”  in  the  Index)  and  for  burned-out  bulbs. 
If you  have  a  trailer  towing  option  with  added  wiring  for  the  tr\
ailer  lights,  a 
different  turn  signal  flasher  is  used.  With  this  flasher  instal\
led,  the  signal  indicator  will  flash  even  if  a  turn  signal  bulb  is  burned  out\
.  Check  the  front 
and  rear  turn  signal  lights  regularly  to make  sure  they  are  working. 
Operation of Lights 
Although  your  vehicle’s  lighting  system  (headlights,  parking  \
lights,  fog  lamps, 
side  marker  lights  and  tail  lights)  meet  all  applicable  Federa\
l  lighting 
requirements,  certain  states  and  providences  may  apply  their  own\
  lighting 
regulations  that  may  require  special  attention  before  you  operat\
e  these  lights. For  example,  some  jurisdictions  may  require  that  you  operate  yo\
ur  lower 
beam  lights  with  fog  lamps  at  all  times,  or  that  headlights  b\
e  turned  on 
whenever  you  must  use  your  windshield  wipers.  In  addition,  most\
  jurisdictions 
prohibit  driving  solely  with  parking  lights,  especially  at  dawn \
 or  dusk. 
It is 
recommended  that  you  check  with  your  own  state  or  provincial  h\
ighway 
authority  for  applicable  lighting  regulations.

Fuses and Circuit  Breakers 
The  wiring  circuits  in your  vehicle  are  protected  from  short  circuits  by a 
combination  of fuses,  circuit  breakers,  and  fusible  thermal  links  in the  wiring 
itself.  This  greatly  reduces  the  chance  of fires  caused  by  electrical  problems.

Downloaded from www.Manualslib.com manuals search engine Be  sure to use  the  correct  fuse. If you  ever  have  a  problem  on  the  road  and 
don’t  have  a  spare  fuse,  you  can  “borrow”  one  of the  correct  value.  Just  pick 
some  feature  of your  vehicle  that  you  can  get  along  without-like the  radio or 
cigarette  lighter-and  use  its  fuse, 
if it is  of  the  value  you  need.  Replace it 
as  soon  as you  can.  See  “Fuses  and  Circuit  Breakers”  in this  section.
