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.

Sunroof Your vehicle may  be equipped  with  a  sunroof.  The 
sunroof  includes  a sliding  glass  panel  and  a  one-piece 
sunshade.  The switch  to control the  sunroof is 
located  in the headliner on the  roof  panel.  The  switch 
works  only while the  ignition is on  or 
RAP is active. 
See  Ignition  Positions  on  page 
2- 19. 
Vent: Push the  rear  of the switch  once  and  the  sunroof 
will  open  to the vent  position  only.  You  will  need to 
open the sunshade  by  hand. 
Open/Express-Open: Push the rear of the  switch  a 
second time and the  sunroof  will  open  the  remainder  of 
the  way.  This is the  express-open  feature. 
Close: Push and hold the front  of the  switch  until  the 
sunroof  motor stops.  The  sunshade  must  be  closed 
by  hand.

Delayed Exit Lighting 
For exiting the vehicle at  night, the vehicle is equipped 
with  the  delayed exit lighting feature. The  interior 
lamps  will  illuminate  for  up to 
25 seconds  when  you 
remove  the key from  the ignition.  After 
25 seconds  have 
elapsed, the  interior  lamps will slowly fade  out. The 
lamps  will  fade out before the 
25 seconds  have  elapsed 
if you do any  of the following: 
Insert  the  key  and turn the  ignition to RUN or 
ACCESSORY. 
Lock all doors using  the  remote keyless entry 
Lock  the doors using  the  power  door  lock switch. 
transmitter 
(if equipped). 
When  any  door  is opened,  delayed exit lighting  is 
canceled.  The interior  lamps will stay  on while  any  door 
is opened and will slowly fade out  when all the  doors 
are closed.  The interior  lamps  may  stay on  for  up 
to 
25 seconds  after all the doors  have  been  closed if 
they  have not  been locked.  See  Delayed  Illumination 
and  Exit lighting  on page 
2-44. 
Overhead  Console  Reading  Lamps 
Your vehicle  may  have  reading lamps  on  the  overhead 
console.  These  lamps  will turn on  when  you  open 
the  doors.  When  the doors  are  closed,  push  the button 
next  to each  lamp 
to turn  them  on  and off. The 
overhead  console also contains  an  open  storage  bin. 
Front Reading  Lamps 
If the vehicle  has the optional  sunroof, you will have 
reading  lamps in front  of the  sunroof  switch  located on 
the  headliner.  These  lamps  will  come  on  when  you 
open  the doors.  The  lamps  can  be  turned on  and 
off 
manually  by pressing  the button behind  each  reading 
lamp  when  the  doors are  closed. 
Rear  Assist  Handle  Reading  Lamps 
Your vehicle  may  have  reading lamps  on  each 
rear assist handle. Press  the reading  lamp 
to turn it  on. 
Press  it again to turn  it 
off. 
To turn  the  delayed exit lighting feature off or on, 
see  Vehicle Personalization  on page 
2-43.

Instrument Panel Fuse Block 
Some fuses are in a  fuse  block  located inside  of  the 
glove  box behind a  small bin on the  right  side.

pull the cover  out.  The  fuse  block  is inside.  On the 
back  edge  of this  cover  is a  fuse  usage chart. 
To reinstall  the  bin,  position  the  lower  end  and turn  the 
top  into  position.  Press  on  the  sides  until it snaps 
into place.
