Speedometer
The speedometer shows the vehicle
speed in both kilometers per hour
(km/h) and miles per hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven in either
miles (used in the United States) or
in kilometers (used in Canada).
This vehicle has a tamper-resistant
odometer. If the odometer displays
ERROR, it probably has been
tampered with and the numbers
might not be accurate.
If the vehicle needs a new odometer
installed, it must be set to the
mileage total of the old odometer.
If that is not possible, then it will be
set at zero and a label must be put
on the driver door to show the old
mileage reading of the vehicle when
the new odometer was installed.
Tachometer
The tachometer displays the engine
speed in revolutions per
minute (rpm).
Notice:If the engine is operated
with the tachometer in the shaded
warning area, the vehicle could
be damaged, and the damages
would not be covered by the
vehicle warranty. Do not operate
the engine with the tachometer in
the shaded warning area.

If the front passenger safety belt is
buckled, neither the chime nor the
light comes on.
The front passenger safety belt
reminder light and chime may turn
on if an object is put on the seat
such as a briefcase, handbag,
grocery bag, laptop, or other
electronic device. To turn off the
reminder light and/or chime, remove
the object from the seat or buckle
the safety belt.Airbag Readiness Light
The system checks the airbag's
electrical system for possible
malfunctions. If the light stays on it
indicates there is an electrical
problem. The system check includes
the airbag sensor(s), passenger
sensing system, the pretensioners,
the airbag modules, the wiring, and
the crash sensing and diagnostic
module. For more information on the
airbag system, seeAirbag System
on page 3‑20.
The airbag readiness light flashes
for a few seconds when the engine
is started. If the light does not come
on then, have it fixed immediately.
{WARNING
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in
the vehicle might not inflate in a
crash, or they could even inflate
without a crash. To help avoid
injury, have the vehicle serviced
right away.
If there is a problem with the airbag
system, an airbag Driver Information
Center (DIC) message can also
come on. See Vehicle Messages on
page 5‑29 for more information.

Passenger Airbag Status
Indicator
The vehicle has the passenger
sensing system. SeePassenger
Sensing System on page 3‑28 for
important safety information. The
instrument panel has a passenger
airbag status indicator.
United States
Canada When the vehicle is started, the
passenger airbag status indicator
will light ON and OFF, or the symbol
for on and off, for several seconds
as a system check. If you are using
remote start, if equipped, to start the
vehicle from a distance, you may
not see the 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 frontal
airbag.
If the word ON or the on symbol is
lit on the passenger airbag status
indicator, it means that the right
front passenger frontal airbag is
enabled (may inflate).
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 frontal airbag. If, after several seconds, both 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.
{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. See
Airbag Readiness
Light on page 5‑14 for more
information, including important
safety information.
