New Vehicle “Break-In” - 3500 HD Model 
If you have a 3500 HD model, your parking brake requires a special 
break-in  procedure.  See “Parking  Brake” 
in the Index. 
Ignition Switch 
Use  your  key to start your  vehicle.  The key lets you turn the ignition switch 
to  five  different positions: 
2 
5 
1. OFF 
2. RUN 
3. START 
4. ACC 
5. LOCK 
ACC  (Accessory): 
ACC lets you use things like the radio, power  windows 
and the windshield  wipers when the engine is off. To get into ACC, push in 
the key and turn it toward you.  Your steering  wheel  will  remain locked,  just 
as it was before you inserted  the key. 
LOCK: This  position  locks your ignition,  steering wheel and  transmission. 
It’s 
a theft deterrent  feature. You will only  be able  to remove  your key  when 
the ignition 
is turned  to LOCK. 
OFF: This position  lets  you turn  off the  engine  but still  turn the steering 
wheel.  It  doesn’t lock the  steering wheel like  LOCK. Use 
OFF if  you must 
have  your  vehicle 
in motion while the  engine is off (for example, if your 
vehicle  is  being pushed). 
RUN: This is the position  for  driving. 
START:  This  starts  your engine.

When the high beams 
are 
on. this blue light 
on  the instrument 
panel  also 
will be on. 
Windshield  Wipers 
You  contro: the 
windshield  wipers  by 
turning the  band  with 
the  wiper symbol 
on 
it. 
..... ".. ....  ~.. 
For  a  single wiping  cycle, turn  the  band to MIST.  Hold it there until the 
wipers  start, then let 
go. The wipers  will stop  after  one  cycle.  If  you want 
more  cycles,  hold the band 
on MIST longer. 
You can set the wiper  speed for a long or short delay between  wipes.  This 
can  be very useful  in light  rain 
or snow.  Turn the band to  choose the delay 
time.  The  closer  to LOW,  the shorter  the delay. 
For steady wiping  at  low speed,  turn  the  band  to the LOW position.  For  high 
speed  wiping, 
turn the band  further, to HIGH. To stop  the wipers, move  the 
band to the 
off symbol. 
Remember  that damaged  wiper blades  may prevent  you from  seeing  well 
enough 
to drive  safely.  To avoid  damage,  be sure  to clear  ice  and snow from 
the wiper blades before using  them. 
If they are frozen  to the  windshield, 
carefully  loosen  or thaw  them. 
If your blades  do become  damaged,  get new 
blades  or blade  inserts.

Heavy snow  or ice can overload your wipers.  The windshield wiper motor  is 
protected  from overload  by 
a circuit breaker and  a  fuse. If the motor 
overheats  due  to heavy snow,  etc., the wiper will  stop 
until the motor cools. 
Although the circuit  is protected from electrical  overload, overload due 
to 
heavy  snow,  etc. may  cause wiper linkage damage.  Always  clear ice and 
heavy  snow from the windshield  before using your windshield wipers. 
Windshield Washer 
At the top of the  lever 
there’s  a paddle with 
the  word 
PUSH on it. 
To spray washer fluid 
on the windshield, 
push  the paddle. 
Washer fluid  will spray 
as long  as you  push  the paddle. When  you  let go of 
the paddle,  the wipers  will continue  to  wipe for a few seconds  and then 
either  stop 
or return to the preset  speed. 
Driving  without washer fluid  can  be dangerous. 
A bad  mud  splash can block 
your  vision.  You could 
hit another vehicle  or  go off the  road.  Check  your 
washer fluid level  often. 
A CAUTION: 
In  freezing  weather,  don’t  use  your  washer  until  the  windshi\
eld 
is  warmed.  Otherwise  the  washer 
fluid can form ice on the 
windshield,  blocking  your  vision.

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.  See “Fuses  and Circuit  Breakers’’ 
in the Index  for more 
information. 
Headlamps 
The headlamp  wiring is protected by a  circuit breaker in the lamp  switch. 
An  electrical  overload  will cause 
the lamps to flicker  on and off, or in some 
cases  to  remain 
off. If this  happens,  have  your  headlamp  wiring checked 
right  away. 
Windshield  Wipers 
The  windshield  wiper motor  is protected  by a clrculc DreaKer  ana a ruse. 11 
the motor  overheats due to heavy  snow, etc., the wiper  will stop  until the 
motor  cools.  Although  the  circuit  is protected  from electrical  overload, 
overload  due to heavy  snow,  etc., may  cause  wiper  linkage  damage.  Always 
clear  ice  and heavy  snow  from  the the windshield  before  using  the 
windshield  wipers. If the  overload 
is caused  by some  electrical  problem and 
not snow,  etc., be sure 
to get it fixed. 
Power  Windows and Other  Power  Options 
Circuit  breakers in the  fuse  panel  protect the power windows  and  other 
power  accessories.  When  the current  load is too  heavy, the  circuit breaker 
opens  and  closes.  This  protects  the circuit 
until the current  load returns to 
normal or the  problem  is  fixed. 
Trailer  Wiring  Harness 
The standard  seven-wire  trailer  wiring  harness is protected  by an in-line 
fuse  in the  battery  feed wire.  This  fuse  is near the  junction  block. See 
“Trailer Wiring Harness”  in the  Index  for  more  information.
