Starting  and  Operating Your 
Vehicle 
New Vehicle  Break-In 
Notice: Your vehicle  doesn’t  need  an  elaborate 
“break-in.”  But 
it will  perform  better in the  long run 
if  you  follow  these  guidelines: 
Don’t  drive  at any  one  speed - fast  or 
slow 
- for  the  first 500 miles (805 km). 
Don’t  make  full-throttle  starts. 
Avoid  making  hard  stops  for  the  first 200 miles 
(322 km)  or so. During  this  time  your  new 
brake  linings  aren’t  yet  broken 
in. Hard  stops 
with  new  linings  can  mean  premature  wear and 
earlier  replacement. 
Follow this breaking-in 
guideline  every  time  you  get  new  brake  linings. 
Don’t  tow  a  trailer  during  break-in.  See “Towing 
a  Trailer” 
in the  Index  for  more  information. 
Ignition Positions 
With the  key in the ignition,  you  can  turn it to  five 
different positions. 
A 
A E 
A (ACCESSORY): This is  the position  in which  you  can 
operate your electrical  accessories. Press in the  ignition 
switch 
as you  turn  the  top of the key  toward  you. 
2-32  

Automatic  Transaxle  Operation 
Maximum engine speed is  limited  when you’re  in 
PARK  (P)  or  NEUTRAL 
(N), to  protect driveline 
components  from improper operation. 
There  are  several different positions for  your shift  lever 
PARK  (P): This  gear  position locks your front wheels. 
It’s the  best position  to use  when  you  start your 
engine  because  your  vehicle can’t move easily. 
Ensure  the shift lever  is fully  in PARK  (P)  before starting 
the  engine.  Your vehicle  has an automatic transaxle shift 
lock control  system.  You  have  to fully 
apply your regular 
brakes 
before you  can  shift from  PARK (P) when the 
ignition  key is in  RUN. 
As you  step  on the  brake pedal, 
while  in PARK 
(P), you  may  hear a click from  the solenoid 
of  the  system. This  ensures that the system  is operating 
properly. 
If you  cannot  shift out of  PARK  (P),  ease  pressure on 
the shift lever - push  the  shift  lever all the  way  into 
PARK  (P)  as you  maintain brake  application.  Then  move 
the  shift  lever into the  gear  you  wish.  See  Shifting 
Out 
of Park (P) on page 2-42. 
It is dangerous  to  get  out  of your  vehicle  if the 
shift lever is not  fully  in  PARK (P) with  the 
parking  brake  firmly 
set. Your  vehicle  can  roll. 
Don’t  leave  your  vehicle  when  the  engine  is 
running  unless  you  have to. If you  have  left  the 
engine  running, 
the vehicle  can  move  suddenly. 
You  or  others  could  be  injured.  To be sure  your 
vehicle  won’t  move,  even when  you’re  on  fairly 
level  ground,  always  set  your  parking  brake  and 
move  the 
shift lever  to  PARK (P).  See  “Shifting 
Into  Park  (P)” 
in the  Index.  If  you’re  pulling a 
trailer,  see  “Towing  a  Trailer”  in  the Index. 
2-36  

Warm-up Shift 
Your vehicle has a computer controlled transaxle 
designed  to warm  up the engine  faster  when the  outside 
temperature  is 
35°F (2°C) or colder.  You  may notice 
that  the transaxle will shift at a higher vehicle speed until 
the engine is warmed  up. This  is a  normal condition 
designed  to provide heat  to the  passenger compartment 
and defrost the  windows more quickly.  See 
Climate 
Control  System  on 
page 3-25 for more information. 
THIRD 
(3): This  position  is also used for  normal driving, 
but  it  offers  more power and lower fuel  economy than 
AUTOMATIC  OVERDRIVE (D). 
Here are  some times you  might choose THIRD 
(3) 
instead  of AUTOMATIC  OVERDRIVE (D): 
When driving on hilly, winding  roads. 
When towing a trailer (so there is less shifting 
When going down a steep hill. between gears). 
SECOND 
(2): This  position gives  you more power, 
but lower fuel economy.  You can  use SECOND 
(2) on 
hills. It can help control  your speed as you  go down 
steep mountain roads,  but then you would also want to 
use your  brakes 
off and  on. 
Notice: Don’t  drive  in  SECOND (2) for  more  than 
25 miles (40 km), or at speeds  over 55 mph (90 km/h), 
or  you  can  damage  your  transaxle.  Use  THIRD 
(3) or 
AUTOMATIC  OVERDRIVE (D) as much  as possible. 
Don’t 
shift into  SECOND (2) unless  you  are  going 
slower  than 
65 mph (105 km/h)  or  you  can  damage 
your  engine. 
Notice: If your  vehicle  seems to start up  rather 
slowly,  or  if 
it seems  not  to  shift gears as you  go 
faster,  something  may  be  wrong  with  a  transaxle 
system  sensor.  If  you  drive  very  far  that  way, your 
vehicle  can  be  damaged. 
So, if  this happens,  have 
your  vehicle  serviced 
right away.  Until then,  you can 
use  SECOND 
(2) when  you  are driving  less  than 
35 mph (55 km/h)  and  THIRD (3) for  higher speeds. 
FIRST 
(1): This position  gives  you  even  more  power 
(but  lower  fuel economy)  than 
SECOND (2). You  can  use 
it  on  very  steep  hills, or in deep  snow  or  mud. 
If the  shift 
lever is  put in FIRST 
(I), the transaxle  won’t downshift 
into  first  gear  until the vehicle is going  slow  enough. 
Notice: If  your  front  wheels  won’t  turn, don’t  try  to 
drive.  This  might  happen  if  you  were stuck  in  very 
deep  sand  or  mud  or  were up  against  a  solid  object. 
You could  damage  your  transaxle.  Also, if  you  stop 
when  going 
uphill, don’t  hold  your  vehicle  there  with 
only  the  accelerator  pedal. This  could  overheat  and 
damage  the  transaxle.  Use  your  brakes  to  hold  your 
vehicle  in  position  on  a 
hill. 
2-38  

Parking  Brake 
The parking brake is 
located on the  driver’s 
side  under the 
instrument panel. 
If the ignition  is on,  the  brake  system warning light will 
come  on. See 
Brake  System  Warning  Light on 
page 3-44. 
To release  the parking brake, hold  the regular  brake 
pedal down with  your right foot  while  you push down on 
the parking brake pedal with  your  left foot. (To release 
the tension  on the  parking brake cable, you will  need to 
apply  about the  same amount  of pressure to  the 
parking brake pedal as you did  when you set  the  parking 
brake.)  When you  remove  your  foot from the  parking 
brake  pedal, 
it will pop  up  to the  released position. 
Notice: Driving with the parking  brake  on  can  cause 
your  rear  brakes to  overheat.  You  may  have to 
replace  them, and you  could  also damage  other 
parts 
of your  vehicle. 
To  set  the  parking brake, hold the  regular brake pedal  If

Running Your  Engine While You 
Are 
Parked 
It’s better not  to park with the engine running. But if you 
ever  have  to,  hpre are some  things 
to know. 
Idling  the  engine  with  the  climate  co~,.,ol 
system 
off could  allow  dangerous  exhaust  into 
your  vehicle.  See the  earlier  Caution  under 
“Engine  Exhaust.” 
Also,  idling 
in a  closed-in  place  can  let  deadly 
carbon  monoxide  (CO) into  your  vehicle  even 
if  the  fan 
is at  the  highest  settin:,.  One place 
this can  happen  is a garage.  Exhaust - with 
CO - can  come  in  easily.  NEVEt3 park  in  a 
garage  with  the  engine  running. 
Another  closed-in  place  can  be  a  blizzard.  See  “Winter  Driving”  in  the  Index. 
It can De dangerous  to get  out  of your  vehicle 
if  the 
shift lever  is  not  fully  in  PARK  (P) with 
the  parking  brake  firmly  set. Your  vehicle  can 
roll.  Don’t  leave  your  vehicle  when  the  engine 
is running  unless  you  have  to. If you’ve  left 
the  engine  running,  the  vehicle  can  move  suddenly.  You or  others  could  be  injured. 
To be  sure  your  vehicle  won’t  move, even 
when  you’re  on  fairly  level  ground,  always  set  your  parking  brake  and  move  the  shift  lever 
to  PARK  (P). 
Follow the proper steps to be sure  your  vehicle  won’t 
move.  See 
Shifting  Into  Park  (P) on page 2-40. 
If you’re pulling a trailer, see Towing a Trailer on 
page 4-36. 
2-44  

Turn and Lane-Change Signals 
The turn  signal  has  two  upward (for right)  and  two 
downward  (for left) positions.  These positions allow  you 
to  signal a turn  or  a lane  change. 
To signal  a turn,  move  the lever  all  the  way  up  or 
down.  When  the turn is finished, the  lever will  return 
automatically. 
-1 An  arrow  on the  instrument 
panel cluster will flash  in 
the  direction  of the 
turn  or lane  change. 
To  signal  a lane  change,  just  raise  or lower  the lever 
until  the arrow 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 change, 
if the arrow 
flashes faster  than normal,  a signal bulb  may be 
burned  out  and  other drivers  won’t  see  your turn signal. 
If a bulb  is burned  out,  replace it to help avoid  an 
accident.  If the arrows don’t go  on  at all when  you  signal 
a  turn,  check  for  burned-out bulbs  and  check the 
fuse.  See 
Bulb Replacement on page 5-52 and Fuses 
and  Circuit  Breakers on page 
5-96. 
If you  have  a  trailer towing option with  added  wiring  for 
the  trailer lamps,  the signal  indicator will  flash  at a normal 
rate  even 
if a turn signal bulb is burned  out.  Check  the 
front  and  rear  turn signal  lamps  regularly  to  make  sure 
they are  working. 
Turn  Signal On Chime 
If either turn signal is left  on  for  more  than 3/4 mile 
(1.2 km),  a  chime  will sound  to let the  driver  know  to 
turn 
it off. 
If you  need  to leave  the signal on for  more  than  3/4  mile 
(1.2 km),  turn off the signal  and  then turn it  back  on. 
Headlamp  High/Low-Beam  Changer 
To change the headlamps  from high to  low  beam, or 
low  to  high,  simply pull the turn  signal  lever  all  the  way 
toward  you.  Then  release it. 
When  the high beams 
are on,  this  light  on  the 
instrument  panel  cluster 
will also  be  on. 
Your  fog lamps  will turn 
off when  you  switch  to 
high  beams.  Using your high beams  in fog  is  not 
recommended.
