Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell 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.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the following

Ignition Positions
The ignition switch is located on the instrument panel,
to the right of the steering column.
There are four different
positions. Insert the key
in the ignition and turn
it to the right for each
position.
9(OFF):This position locks the ignition, steering
wheel and transaxle. It is a theft-deterrent feature. This is
the only position from which the key can be removed.
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
it is, turn the steering wheel left and right while you
turn the key hard. If none of this works, then
your vehicle needs service.ACC (ACCESSORY):This position allows things like
the radio and windshield wipers to operate while
the engine is off.
R(RUN):This position is where the key returns to
after the vehicle is started. With the engine off, the
RUN position displays some of the warning and
indicator lights.
/(START):This position starts the engine. Let go of
the key when the engine starts. The key will return
to the RUN position for normal driving.
A continuous warning chime will sound and a KEY IN
IGNITION warning message will display on the
Driver Information Center (DIC) if the key is in the
ignition in OFF or ACC and the driver’s door is opened.
Retained Accessory Power (RAP)
If the vehicle has Retained Accessory Power (RAP),
certain features will continue to operate for up to
10 minutes after the ignition key is turned to OFF unless

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on the vehicle. The pictures help to locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. As
the details show on the next few pages, some warning
lights come on briey when the engine is started
just to indicate they are working. If you are familiar
with this section, you should not be alarmed when
this happens.Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate when there is a
problem with the vehicle.
When one of the warning lights comes on and stays on
while the vehicle is being driven, or when one of the
gages shows there may be a problem, check the section
that tells you what to do about it. Follow this manual’s
advice. Waiting to do repairs can be costly – and
even dangerous. So please get to know the vehicle’s
warning lights and gages. They can be a big help.
The vehicle also has a Driver Information Center (DIC)
that works along with the warning lights and gages.
SeeDriver Information Center (DIC) on page 3-49for
more information.
