Safety  Warnings  and Symbols 
You  will find a number of safety cautions in this book. 
We  use  a  box  and  the  word  CAUTION  to tell  you  about 
things that could hurt  you 
if you  were to ignore the 
Y ning. 
I 
These  mean  there is something that could hurt 
you  or other  people. 
In the  caution  area, we tell  you  what  the hazard  is. 
Then  we  tell you  what  to do  to help avoid  or reduce the 
hazard.  Please read these cautions. 
If you  don’t,  you 
or  others could  be  hurt.  You 
will also  find  a 
circle with  a slash 
through  it  in  this  book. 
This safety  symbol 
means 
“Don’t,’’ 
“Don’t  do this”  or 
“Don’t  let this  happen.” 
iii  

Vehicle Damage  Warnings 
Also, in this  book  you  will find these  notices: 
Notice: These mean there is something that could 
damage  your  vehicle. 
A notice will tell  you  about  something  that can damage 
your vehicle.  Many  times, this damage  would  not  be 
covered  by your  warranty, and  it  could  be costly. 
But  the notice will tell  you what  to do  to  help avoid the 
damage. 
When  you read other  manuals, you might  see 
CAUTION  and  NOTICE  warnings  in different colors 
or 
in different words. 
You’ll  also see warning labels 
on your vehicle.  They 
use  the  same  words,  CAUTION  or NOTICE. 
Vehicle Symbols 
Your  vehicle  has  components  and  labels that use 
symbols  instead of text.  Symbols,  used  on  your  vehicle, 
are  shown  along with  the text describing the operation 
or  information relating to  a specific  component,  control, 
message,  gage  or  indicator. 
If you  need help figuring  out a specific name of a 
component,  gage  or  indicator reference the following 
topics: 
Seats  and  Restraint Systems in Section 1 
Features and Controls in Section 2 
Instrument Panel  Overview in Section 3 
Climate Controls in  Section 3 
Warning Lights, Gages  and  Indicators in Section 3 
Audio  System(s) in Section 3 
Engine  Compartment  Overview  in Section 5 
iv  

Notice: If your  key  seems stuck in LOCK and  you 
can’t turn  it,  be sure  you  are  using the correct  key; 
if 
so, is  it  all  the  way  in?  Turn the  key only  with 
your  hand.  Using a  tool to force  it could  break  the 
key or the  ignition  switch.  If  none 
of these works, 
then  your  vehicle  needs service. 
B (LOCK): This position locks  the ignition, steering 
wheel  and transaxle. It’s  a theft-deterrent feature. It’s also 
the  only  position from  which  you can remove  the key. 
C (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 
the  vehicle  pushed  or towed. 
D (RUN): This position is  where the key returns to after 
you  start the vehicle.  With the engine 
off, you can  use 
RUN  to  display some of the warning  and indicator lights. 
E (START): This  position starts the engine. 
A  warning  chime  will  sound 
if you  open  the driver’s  door 
while  the ignition  is in 
OFF, LOCK  or  ACCESSORY 
and  the  key is in the  ignition. 
Retained  Accessory  Power  (RAP) 
With  Retained Accessory  Power,  (RAP),  the power 
windows,  audio system  and  sunroof  will continue to work 
up  to 
10 minutes after the ignition  key is turned to 
OFF and  none  of the doors are  opened. 
Starting  Your  Engine 
Move your shift lever  to  PARK (P) or  NEUTRAL (N). 
Your  engine  won’t  start  in any  other position - that’s  a 
safety feature.  To restart  while  you’re  already moving, 
use  NEUTRAL 
(N) only. 
Nofice: Don’t  try to  shift  to  PARK  (P)  if  your 
vehicle  is  moving. 
If you  do,  you  could  damage  the 
transaxle.  Shift  to 
PARK (P) only  when  your 
vehicle  is stopped. 
Shift Lock  Release 
This vehicle  is equipped  with  an  electric shift  lock 
release  system.  The  shift  lock  release is designed to 
do  the following: 
Prevent ignition  key  removal unless the  shift  lever is 
in PARK  (P)  with the  shift  lever  button fully released. 
Prevent movement  of the  shift lever  out of  PARK  (P) 
unless the  ignition is in a position  other  than 
OFF or 
LOCK.  The  shift lock release  is  always  functional 
except  in the  case 
of a dead  or  low  voltage 
(less than 
9 V) battery. 
2-20  

Parking Brake 
The parking brake is 
located to the  left of 
the 
brake pedai near 
the driver’s  door. 
To  set  the  parking 
brake,  hold the  regular 
brake pedal down with 
the  right  foot.  Push 
down  on  the parking 
brake  pedal,  with  the 
left  foot. 
To release  the  parking brake, hold the regular brake 
pedal  down  with  the right  foot  and push the parking 
brake  pedal with the left foot.  When 
you lift the 
left  foot,  the  parking brake pedal will follow it  to 
the  released  position.  A 
warning chime will sound 
if the parking brake is set, 
the  ignition  is on and the shift lever  is not 
in PARK (P) 
or  NEUTRAL  (N). 
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. 
If you are towing  a trailer and parking  on a hill, see 
Towing a  Trailer 
on page 4-37. That section shows what 
to  do first  to keep the trailer from  moving.
