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 when 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 briey 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.

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has
been driven, in either miles or kilometers.
Your vehicle has a tamper-resistant odometer. 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 that will be done.
If it can’t, it will be 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. If the mileage is
unknown, the label should then indicate “previous
mileage unknown”.
Trip Odometer
Your trip odometer shows how far your vehicle has
been driven since the trip odometer was last reset. To
reset the trip odometer to zero, press and hold the
trip/reset button for about two seconds.
Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not be
covered by your warranty. Do not operate the engine
with the tachometer in the shaded warning area.
The maximum rpm is limited in PARK (P) and
NEUTRAL (N) to 4000 rpm by the vehicle’s computer.
This is to prevent engine damage.

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.
If the brake system warning light comes on, there is a
brake problem. Have your brake system inspected
right away.
The BRAKE light is located
in the instrument panel
cluster.
This light should come on briey when you turn the
ignition key to RUN. If it doesn’t come on then, have it
xed so it will be ready to warn you if there’s a
problem.
When the ignition is on, the BRAKE light will come on
when you set your parking brake. The light will stay on if
your parking brake doesn’t release fully.A chime will also sound if the parking brake is not fully
released and the vehicle is moving. If it stays on
after your parking brake is fully released, it means you
have a brake problem.
The BRAKE light will also come on to indicate a low
brake uid level. SeeBrakes on page 5-36for
more information.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the
oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing

Anti-Lock Brake System Warning
Light
If your vehicle has anti-lock brakes, the anti-lock brake
system (ABS) warning light will come on briey, as
a check, when you start your vehicle. If it does not, have
your vehicle serviced so that the light works properly
when it needs to.
The ABS light is located in
the instrument panel
cluster, to the left of the
engine coolant
temperature gage.
If the light stays on longer than a few seconds after you
start your engine, or comes on and stays on while
you are driving, try resetting the system.To reset the system, do the following:
1. If you are driving, pull over when it is safe to do so.
2. Be sure the vehicle is in PARK (P).
3. Turn off the ignition.
4. Then restart the engine.
If the light remains on after resetting the system or comes
on again while driving, your vehicle needs service. If the
ABS light is on, but the regular brake system warning light
is not on, you do not have anti-lock brakes, but you still
have regular brakes. Have your vehicle serviced right
away. If both brake lights are on, you do not have
anti-lock brakes, and there’s a problem with your regular
brakes as well. Have your vehicle towed for service. See

Fuel Gage
When the ignition is on,
the fuel gage tells you
about how much fuel you
have left in your tank.
When the indicator nears empty, the low fuel light will
come on. You still have a little fuel left, but you
should get more soon. SeeLow Fuel Warning Light on
page 3-40for more information.
Here are four things that some owners ask about. None
of these show a problem with your fuel gage:
At the service station, the fuel pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank’s capacity to
ll the tank.
The gage moves a little when you turn a corner or
speed up.
The gage takes a few seconds to stabilize after the
ignition is turned on, and will go back to empty
when you turn the ignition off.
For your fuel tank capacity, seeCapacities and
Specications on page 5-98.
Low Fuel Warning Light
The light next to the fuel
gage will come on briey
when you are starting
the engine.
This light also comes on when the fuel tank is low on
fuel. When you add fuel the light should go off. If it
doesn’t, have your vehicle serviced.

Anti-lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves a little. This is normal.
If there is a problem with
the anti-lock brake system,
this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-31.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.
