Ignition Positions
The key can be turned to one of four positions
while in the ignition switch.
A (LOCK):This is the only position from which
you can remove the key. This position locks
your ignition and transaxle.Notice:Using a tool to force the key from the
ignition switch could cause damage or
break the key. Use the correct key and turn the
key only with your hand. Make sure the key
is all the way in. If none of this works,
then your vehicle needs service.
B (ACCESSORY):This is the position in which
you can operate the electrical accessories, such as
the radio.
C (RUN):This is the position to which the switch
returns after the engine is started and the ignition
key is released. This is the position for driving. Even
while the engine is not running, RUN can be used to
operate your electrical accessories and to display
some instrument panel warning lights.
The battery could be drained if you leave the key in
the ACCESSORY or RUN position with the engine
off. You may not be able to start your vehicle if the
battery is allowed to drain for an extended period
of time.
D (START):This position starts the engine. When
the engine starts, release the ignition key. The
switch will return to RUN for driving.
129

DRIVE (D):This position is for normal driving. It
provides the best fuel economy for your vehicle. If
you need more power for passing, and you are:
Going less than 35 mph (55 km/h), push
your accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push
the accelerator all the way down.
The vehicle will shift down to the next gear
and have more power.
Downshifting the transaxle in slippery road
conditions could result in skidding, see Skidding
underLoss of Control on page 362
Notice:If your vehicle seems to start up
rather slowly or not shift gears when you go
faster, and you continue to drive your vehicle
that way, you could damage the transaxle.
Have your vehicle serviced right away. You can
drive in SECOND (2) when you are driving
less than 35 mph (55 km/h) and DRIVE (D) for
higher speeds until then.
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. SeeClimate
Control System on page 193andDual Climate
Control System on page 197for more information.
THIRD (3):This position is also used for normal
driving. It reduces vehicle speed more than
DRIVE (D) without using your brakes. You might
choose THIRD (3) instead of DRIVE (D) when
driving on hilly, winding roads, when towing
a trailer, so there is less shifting between gears
and when going down a steep hill.
135

SECOND (2):This position reduces vehicle speed
more than DRIVE (D) without using your brakes.
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:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph
(90 km/h) may damage the transaxle. Also,
shifting into SECOND (2) at speeds above
65 mph (105 km/h) can cause damage. Drive in
THIRD (3) or DRIVE (D) instead of SECOND (2).
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 reduces vehicle speed
even more than SECOND (2) without using your
brakes. You can use it on very steep hills, or in
deep snow or mud. If the shift lever is put in
FIRST (1) while the vehicle is moving forward, the
transaxle will not shift into rst gear until the vehicle
is going slowly enough.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only the
accelerator pedal may damage the transaxle. If
you are stuck, do not spin the tires. When
stopping on a hill, use the brakes, or parking
brake to hold the vehicle in place.

Passenger Safety Belt Reminder
Light
Several seconds after the key is turned to RUN or
START, a chime will come on for several seconds
to remind the front passenger to buckle their
safety belt. This would only occur if a passenger is
detected by the passenger sensing system. See
Passenger Sensing System on page 86for more
information. The passenger safety belt light will also
come on and stay on for several seconds, then it
will ash for several more.
You should have the
passenger buckle their
safety belt.
This light and chime reminder will be repeated if
the ignition is on, the vehicle is in motion, the
passenger is still unbuckled and the passenger
airbag is enabled.
If the passenger’s safety belt is buckled, neither
the chime nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the
instrument panel, which shows the airbag symbol.
The system checks the airbag’s electrical
system for malfunctions. The light comes on if
there is an electrical problem. The system check
includes the airbag sensor, the airbag modules,
the wiring and the diagnostic module. For
more information on the airbag system, see
Airbag System on page 76.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should go
out. This means the
system is ready.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.
210

{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays
on after you start your vehicle.
The airbag readiness light should ash for a
few seconds when you turn the ignition key to
RUN. If the light doesn’t come on then, have
it xed so it will be ready to warn you if there is
a problem.
Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
Your instrument panel has a passenger airbag
status indicator.
When the ignition key is turned to RUN or START,
the passenger airbag status indicator will light
ON and OFF, or the symbol for on and off,
for several seconds as a system check. Then,
after several more seconds, the status indicator
will light either ON or OFF, or either the on
or off symbol to let you know the status of the
right front passenger’s frontal airbag and
side impact airbag (if equipped).
United StatesCanada
211

If the word OFF or the off symbol is lit on the
airbag status indicator, it means that the
passenger sensing system has turned off the
right front passenger’s airbag or airbags.
SeePassenger Sensing System on page 86
for more on this, including important safety
information.
If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag readiness
light ever come on together, it means
that something may be wrong with the
airbag system. If this ever happens, have
the vehicle serviced promptly, because
an adult-size person sitting in the right
front passenger seat may not have the
protection of an airbag. SeeAirbag
Readiness Light on page 210.
Charging System Light
The charging system
light will come on
briey when you turn on
the ignition, but the
engine is not running,
as a check to show you
it is working.
It should go out once the engine is running. If it
stays on, or comes on while you are driving,
you may have a problem with the charging system.
It could indicate that you have problems with a
generator drive belt, or another electrical problem.
Have it checked right away. Driving while this
light is on could drain your battery.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and air conditioner.
