The DTE function will display FUEL LEVEL LOW and sound a tone for
one second when you have approximately 50 miles (80 km) to empty. If
you RESET this warning message, this display and tone will return
within 10 minutes or 10 miles (16 km).
DTE is calculated using a running average fuel economy, which is based
on your recent driving history of 500 miles (800 km). This value is not
the same as the average fuel economy display. The running average fuel
economy is reinitialized to a factory default value if the battery is
disconnected.
AVERAGE FUEL XX.X MPG (L/100km)
Average fuel economy displays your average fuel economy in miles/gallon
or liters/100 km.
If you calculate your average fuel economy by dividing gallons of fuel
used by 100 miles traveled (kilometers traveled by liters used), your
figure may be different than displayed for the following reasons:
•Your vehicle was not perfectly level during fill-up
•Differences in the automatic shut-off points on the fuel pumps at
service stations
•Variations in top-off procedure from one fill-up to another
•Rounding of the displayed values to the nearest 0.1 gallon (liter)
1. Drive the vehicle at least 5 miles (8 km) with the speed control
system engaged to display a stabilized average.
2. Record the highway fuel economy for future reference.
It is important to press the RESET control (press and hold RESET for
two seconds in order to reset the function) after setting the speed
control to get accurate highway fuel economy readings.
FUEL ECONOMY MPG (L/km)
This displays instantaneous fuel economy as a bar graph ranging from↓
poor economy to↑excellent economy.
Your vehicle must be moving to calculate instantaneous fuel economy.
When your vehicle is not moving, this function shows↓, one or no bars
illuminated. Instantaneous fuel economy cannot be reset.
TIMER
Timer displays the trip elapsed drive time.
To operate, do the following:
1. Press and release RESET in order to start the timer.

BULB REPLACEMENT
Lamp assembly condensation
Exterior lamps are vented to accommodate normal changes in pressure.
Condensation can be a natural by-product of this design. When moist air
enters the lamp assembly through the vents, there is a possibility that
condensation can occur when the temperature is cold. When normal
condensation occurs, a thin film of mist can form on the interior of the
lens. The thin mist eventually clears and exits through the vents during
normal operation. Clearing time may take as long as 48 hours under dry
weather conditions.
Examples of acceptable condensation are:
•Presence of thin mist (no streaks, drip marks or droplets)
•Fine mist covers less than 50% of the lens
Examples of unacceptable moisture (usually caused by a lamp water
leak) are:
•Water puddle inside the lamp
•Large water droplets, drip marks or streaks present on the interior of
the lens
Take your vehicle to dealer for service if any of the above conditions of
unacceptable moisture are present.

Front safety belt pretensioners
The safety belt pretensioners at the front outboard seating positions are
designed to tighten the safety belts firmly against the occupant’s body
during frontal collisions and in side collisions. This helps increase the
effectiveness of the safety belts. In frontal collisions, the safety belt
pretensioners can be activated alone or, if the collision is of sufficient
severity, together with the front airbags.
Front safety belt energy management retractors
The front outboard safety belt energy management retractors allow
webbing to be pulled out of the retractor in a gradual and controlled
manner in response to the occupant’s forward momentum. This helps
reduce the risk of force-related injuries to the occupant’s chest by
limiting the load on the occupant. Refer toEnergy management feature
section in this chapter.
Determining if the Personal Safety System™ is operational
The Personal Safety System™ uses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to theWarning light and chimessection in theInstrument Cluster
chapter. Routine maintenance of the Personal Safety System™ is not
required.
The Restraints control module (RCM) monitors its own internal circuits
and the circuits for the airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, front
passenger sensing system, and the driver seat position sensor. In
addition, the RCM also monitors the restraints warning light in the
instrument cluster. A difficulty with the system is indicated by one or
more of the following.
•The warning light will either flash or stay lit.
•The warning light will not illuminate immediately after ignition is
turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.
If any of these things happen, even intermittently, have the Personal
Safety System™ serviced at an authorized dealer immediately. Unless
serviced, the system may not function properly in the event of a
collision.
