Speedometer and Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (kndh).
Your odometer shows how far your vehicle has been
driven,
in either miles (used in the United States) or
kilometers (used
in Canada).
Your odometer is tamper resistant.
It will show silver lines
between the numbers
if someone tries to turn it back.
You may wonder what happens
if your vehicle needs a
new odometer installed. If the new one can be set to the
mileage total of the old odometer, then
it must be. But if
it can't, then it's set at zero, and a label must be put on
the driver's door to show the old mileage reading when
the new odometer was installed.
Trip Odomet
The trip odometer can tell you how fir your vehicle has
been driwn since you last set the
trip odometer to zero.
To set the trip odome.ter to zero, press the button near
the readout.
Tachometer (If Equipped)
The tachometer displays the engine speed in revolutions
ner minute (rprn). Each
tachometer has
a different limit depending on the
powertrain
in your vehicle. The tachometer has three
areas: normal operating range, red warning range and
red danger range.
The normal operating range shows your engine speed
during normal driving conditions.
For example, when
the needle points
to 2, it means the engine is running at
2.000 revolutions per minute (rpm). The tachometer
needle
will vary all the time that the engine is running.
The shaded red warning range tells you that your engine
speed
is reaching its upper limits. Don't drive very long
with the tachometer
in the red warning range. If you
have
a manual transmission. shift to a higher gear as
soon as possible. If you have an automatic transmission,
lift your foot off of the accelerator pedal.
The solid red danger range tells you that your engine speed
is at its upper limits. Your should immediately shift
to a
higher gear, or lift your foot off of the accelerator pedal.
1 NOTICE:
Do not operate the engine with the tachometer in
the red range,
or engine damage will occur.

Warning Lights, Gages and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures
will help you
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
your warning lights and gages could also save you or
others from
injury.
Warning lights come on wl1e.n there may be or is a
problem with one of your vehicle’s functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to
let you know they’re 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 your vehicle’s functions. Often gages and
warning lights work together to
let you know when
there’s
a problem with your vehicle. 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.
Safety Belt Reminder Light
When the key is turned to RUN or START, a tone will
come on for about eight seconds to remind people to
fisten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light
will
also come on and stay on
for about
20 seconds,
then
it will flash for about
55 seconds. If the driver’s
belt is already buckled,
neither the tone nor the
light
will come on.

Air Bag Readiness Light
There is an air bag readiness light 011 the instrument
panel, which shows
AIR RAG. The system checks the
air bag's electrical system for ~~~alfunctions. The light
tells you if there is an electrical problem. The syslem
check includes the air bag sensors. the air
bag module,
the wiring and the diagnostic module. For n~ore
information

the Index.
AIR
BAG
This light will ~0111e on

If the air bag readiness light stays 011 after you start the
engine or comes on when you are driving, your ail- bag
system
may not work properly. Have your vehicle
serviced right

Voltmeter Gage
When your engine is not
running. but the ignition is
on (in the RUN position).
this gage shows
your
battery’s state of charge in
DC volts.
VOLTS
When the engine is running, the gage shows the
condition
of the. charging system. Readings between the
low and high warning zones indicate the normal
operating range. Readings
in the
low warning mne may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since
the
charging system is not able to provide full power at
engine idle. As engine speeds are increased, this
condition should correct itself
as higher engine speeds
allow the charging system to create maximum power.
You can only drive for a short time with the reading in
either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings
in either warning zone indicate a possible
problem
in the electrical system. Have the vehicle
serviced
as soon as possible.

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 you are towing a trailer. reduce the anlount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains
on steady. see “If
the Light Is On Steady” following.
If the light continues t.o flash, when it is safe to do so.
stop the \?el?ic&~. Find a safe place to park your vehiclc.
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 recently put fuel into your vehicle?
If so, reinstall the fuel cap, making s111-e to fully install
the cap. The diagnostic system can cleter~nine
if the fuel cap
has been left off
or improperly installed. A loose or
missing fuel cap
will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed should turn
the light off,
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?
I1 so, be sure to fuel your vehicle with cpality fuel (see
“Fuel”
in the Index). Poor fuel quality will cause your
engine not to
r11n as e,fficiently as designed. You may
notice this
as stalling after start-up, stalling when you put
the vehicle
into gear, mistlring, 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
problcnls that may have developed.

Engine Oil Pressure Gage
Canadian vehicles indicate pressure in kPa (kilopascals). 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.
1 NOTICE: I
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
