Convex Outside Mirror
Your passenger’s side mirror is convex. A convex
mirror’s surface is curved
so you can see more from the
driver’s seat.
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If
you cut too sharply into the right lane, you
could hit a vehicle on
your right. Check your
inside mirror or glance over your shoulder before changing lanes.
The electric mirror control is on the driver’s door. To
adjust either mirror, press the
LT (left) or RT (right) switch
to select the mirror, then press the arrows to adjust the
direction of the mirror. The selected mirror will stay on for
20 seconds after the last adjustment. An indicator light will
come on above the mirror that you select.
Your preferred mirror position can be stored if you have
the memory option. See “Memory” in the Index.
For operation of the heated outside
mirrors, see “Rear
Window Defogger” in the Index.
Storage Compartments
Instrument Panel Cupholder
The cupholder is located on the center console. To open
it, place your thumb on the left side of the lid and raise
the right side with your index finger.

I
I A CAUTION:
An improperly attached roof panel may fall into
or
fly off the vehicle. You or others could be
injured. After installing the roof panel, always
check that it is firmly attached by pushing up
on
the underside of the panel. Check now and then
to
be sure the roof panel is firmly in place.
I NOTICE:
To avoid damage to the roof panel, paint and
weatherstripping, do not drop or rest it on
its edges.
1. Check to be sure that the front handles and rear latch
on the ceiling
are in their opened positions before
attempting to install the roof panel.
2. If the roof panel is stored in the rear area, grasp it
with your right hand at the middle edge near the
seatbacks, and with your left hand at the middle of
the edge closest to you. Reverse the steps described
previously under “Storing the Roof Panel.”
3. Remove the roof panel from the
storage compartment.
4. In most cases, it is easier to install the removable
roof with two people rather than one. Place the roof
panel over the vehicle.

Downloaded from www.Manualslib.com manuals search engine When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to
do about it. Please follow this manual’s advice.
Waiting to do repairs can be costly
-- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.
Your vehicle
also has a Driver Information Center that
works along with the warning lights and gages. See
“Driver Information Center” in the Index.
Safety Belt Reminder Light
When the key is turned to ON or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
- The safety belt light will
also come on and stay
on
until the driver’s belt
is buckled.
Air Bag Readiness Light
There is an air bag readiness light on the instrument’
panel, which shows a deployed air bag symbol. The
system checks the air bag’s electrical system for
malfunctions. The light tells you if there is an electrical
problem. The system check includes the air bag sensors,
the air bag modules, the wiring and the diagnostic
module. For more information on the air bag system, see
“Air Bag” in the Index.
This light will come on
when you start your engine,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to
ON. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you if there is a problem.

Downloaded from www.Manualslib.com manuals search engine Voltmeter
I When the key is in the ON
position with the engine not
running, the voltmeter
shows the voltage output of
your battery. When the
engine is running, it shows
the voltage output of the
charging system.
The reading will change as the rate of charge changes
(with engine speed, for example), but
if the voltmeter
reads at
9 volts or below, your instrument panel and
other systems may shut down. The Driver Information
Center (DIC) will read LOW
VOLTAGE when your
vehicle is at
10 volts or below. Have it checked right
away. Driving with the voltmeter reading at
10 volts or
below could drain your battery and disable your vehicle.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
BRAKE
This light should come on
when you turn the ignition
key to
START. If it doesn’t
come on then, have it fixed
so it will be ready to warn
you
if there’s a problem.
If this warning light stays on after you start the engine,
the parking brake may not be set or there could be a
brake problem. Refer to “Parking Brake” in the Index to
see if it is set. If the parking brake is not set, have your
brake system inspected right away.

Downloaded from www.Manualslib.com manuals search engine Malfunction Indicator Lamp (Check Engine Light)
CHECK
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD
I1 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions
are at acceptable levels for the life
of the vehicle, helping to produce a cleaner
environment. The
CHECK ENGINE light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead
to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
0 Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
Light On Steady -- An emission control system

Downloaded from www.Manualslib.com manuals search engine If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
Avoiding steep uphill’grades.
If the light stops flashing and remains on steady, see
“If
the Light Is On Steady” following.
If the light continues to flash, when it is safe to do
so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least
10 seconds and restart the
engine. If the light remains on steady, see “If the Light
Is On Steady” following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you just drive through a deep puddle of water?
If
so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.
Have you recently changed brands
of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
“Fuel”
in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed.
You may
notice
this as stalling after start-up, stalling when you put
the vehicle into gear, misfiring, hesitation on acceleration or
stumbling on acceleration. (These conditions may go
away once the engine is warmed up.)
This will be detected
by the system and cause the light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light
off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.

Downloaded from www.Manualslib.com manuals search engine Engine Oil Pressure Gage
The engine oil pressure
gage shows the engine oil
pressure in psi (pounds per
square inch) or kPa
(kilopascals) when the
engine is running.
Oil pressure should be
20 to 80 psi (140 to 550 Wa).
(In certain situations such as long, extended idles on hot
days, it could read as low as
6 psi (40 kPa) and still be
considered normal.) It may vary with engine speed,
outside temperature and oil viscosity, but readings above
the shaded area show the normal operating range.
Readings in the shaded area tell you that the engine is
low on oil, or that you might have some other oil
problem. See “Engine Oil” in the Index. The
engine oil pressure can also be displayed using the
GAGES button on the Driver Information Center (DIC).
See “Driver Information Center” in the Index.
A CAUTION:
Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
