Battery voltage gauge
This gauge shows the battery
voltage when the ignition is in the
ON position. If the pointer moves
and stays outside the normal
operating range (as indicated),
have the vehicle's electrical system
checked as soon as possible.
Engine oil pressure gauge
This shows the engine oil pressure
in the system. Sufficient pressure
exists as long as the needle
remains in the normal range (the
area between the ªHº and ªLº).
If the gauge indicates low
pressure, switch off the engine
immediately. Check the oil level.
Add oil if needed (refer to
Checking and adding engine oil
in theMaintenance and care
chapter). If the oil level is correct,
have your vehicle checked at your
dealership or by a qualified
technician.
TRIP COMPUTER
The trip computer tells you about
the condition of your vehicle
through a constant monitor of
vehicle systems. You may select
display features on the trip
computer for a display of status.

Replacing the batteries
The transmitter is powered by one
coin type three-volt lithium battery
CR2032 or equivalent. Typical
operating range will allow you to
be up to 10 meters (33 feet) away
from your vehicle. A decrease in
operating range can be caused by:
²battery weakness due to time
and use
²weather conditions
²nearby radio towers
²structures around the vehicle
²other vehicles parked next to
the vehicle
To replace the battery:
1. Twist a thin coin between the
two halves of the transmitter near
the key ring. DO NOT TAKE THE
FRONT PART OF THE
TRANSMITTER APART.
2. Place the positive (+) side of
new battery in the same
orientation. Refer to the diagram
inside the transmitter unit.
3. Snap the two halves back
together.

If your vehicle is equipped with
the optional heavy duty trailer tow
wiring, it is pre-wired for trailer
towing. An electrical connector is
provided under the instrument
panel for installing a
customer-supplied electric brake
controller. Another electrical
connector is provided at the hitch.
This connector provides power to
the trailer for taillamps, stop and
turn lamps, back up lamps, battery
charge, electric brakes (when a
customer provided controller is
installed) and ground. The kit
included with your vehicle
provides you with adaptors to
attach the brake controller and
convert the hitch connector for
Class I trailer usage.
