Speedometer and
Odometer
The speedometer lets you see your
speed in both miles per hour (mph)
or kilometers per hour (km/h).
The odometer shows how far
your vehicle has been driven,
in either miles or kilometers.
If your vehicle needs a new
odometer installed, the new one will
be set to the mileage total of the old
odometer. If it cannot, 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(s)
The trip odometer, located at the
center of the instrument panel
cluster, tells how far the vehicle
has been driven since the trip
odometer was set to zero.
To reset the trip odometer, hold the
reset stem, located to the right of
the speedometer, for approximately
one second while the trip odometer
is displayed. The engine must
be turned on.
Service Display
The vehicle may have a display
above the odometer that shows
when service is needed. The number
that displays with “INSP” is theremaining distance that can be
driven until service is required.

Doing Your Own
Service Work
{CAUTION
You can be injured and your
vehicle could be damaged if
you try to do service work on a
vehicle without knowing enough
about it.
Be sure you have sufficient
knowledge, experience, the
proper replacement parts, and
tools before you attempt any
vehicle maintenance task.
Be sure to use the proper
nuts, bolts, and other
fasteners. English and metric
fasteners can be easily
confused. If you use the
wrong fasteners, parts can
later break or fall off. You
could be hurt.If you want to do some of your own
service work, you should use the
proper service manual. It tells
you much more about how to
service your vehicle than this
manual can. To order the proper
service manual, seeService
Publications Ordering Information
on page 11-14.
Your vehicle has an airbag system.
Before attempting to do your
own service work, seeAirbag
System Check on page 1-36.
You should keep a record with all
parts receipts and list the mileage
and the date of any service work
you perform. See “Maintenance
Record” in the Limited Warranty,
Maintenance and Owner Assistance
Information manual.
Adding Equipment to the
Outside of the Vehicle
Things you might add to the outside
of your vehicle can affect the
air ow around it. This can cause
wind noise and can affect fuel
economy and windshield washer
performance. Check with your
dealer/retailer before adding
equipment to the outside of your
vehicle.
