: If one of the doors is ajar, a light will appear
next to that door on the vehicle outline.
CHANGE OIL SOON: This light will appear when the
system predicts that the oil's remaining useful life is
almost up. The system predicts remaining oil life using
inputs from length of drives, coolant temperature,
engine rpm and vehicle speed. It alerts you to change
the oil on a schedule consistent with the vehicle's
driving conditions.
After changing the oil, the system must be reset. With
the ignition key in ON but the engine off, fully push and
release the accelerator pedal slowly three times within
five seconds. If the CHANGE OIL SOON light flashes,
the system is resetting. Turn the ignition key to OFF,
then start the vehicle. If the CHANGE OIL SOON light
comes back on, the Oil Life Monitor has not reset.
Repeat the procedure.LOW: This light will come on when the ignition is
on and the fluid container is low.
AJAR: This light alerts you that the trunk is not
fully closed.
LOW TRAC: This light will come on when the
Traction Control System is limiting wheel spin. See
ªTrac Systemº or ªLow Traction Lightº in the Index.
TRAC OFF: This light lets you know that the Traction
Control System has been disabled and will not limit
wheel spin. See ªEnhanced Traction System Warning
Lightº or ªLow Traction Lightº in the Index.
TRAC switch: If the vehicle has the Traction Control
System, you will have a disable switch on the far right
side of the Driver Information Center. The Traction
Control System is automatically activated when you turn
the ignition on. This switch will activate/deactivate the
Traction Control System. If you need to disable the
system, such as when you are stuck and are rocking the
vehicle back and forth, push this switch. See ªStuck: In
Sand, Mud, Ice or Snowº in the Index.

since you last reset this mode. The amount can be
displayed in gallons or liters.AVG ECON: Shows the average fuel economy since
you last reset this mode.
OIL LIFE: Shows a percentage of the oil's remaining
useful life. The system predicts remaining oil life using
inputs from length of drives, coolant temperature,
engine rpm and vehicle speed. Each time you get an oil
change, be sure to reset this function so that it will give
you an accurate percentage. See ªHow to Reset the Oil
Life Monitorº in the Index.
RANGE: Shows how much farther you can travel with
the fuel you have before refueling. When the range
displays L
, for 40 to 50 miles (64.36 to 80.45 km), the
display will flash the word LOW continuously and the
vehicle will chime three times. The range is calculated
from the average econ value times the fuel remaining in
the tank.
LOW: This light will come on when the ignition is
on and the fluid container is low.

Drunken Driving
Death and injury associated with drinking and driving is
a national tragedy. It's the number one contributor to
the highway death toll, claiming thousands of victims
every year.
Alcohol affects four things that anyone needs to drive
a vehicle:

Judgment

Muscular Coordination

Vision

Attentiveness.
Police records show that almost half of all motor
vehicle
-related deaths involve alcohol. In most cases,
these deaths are the result of someone who was drinking
and driving. In recent years, over 17,000 annual motor
vehicle
-related deaths have been associated with the use
of alcohol, with more than 300,000 people injured.
Many adults
-- by some estimates, nearly half the adult
population
-- choose never to drink alcohol, so they
never drive after drinking. For persons under 21, it's
against the law in every U.S. state to drink alcohol.
There are good medical, psychological and
developmental reasons for these laws.The obvious way to solve the leading highway safety
problem is for people never to drink alcohol and then
drive. But what if people do? How much is ªtoo muchº
if the driver plans to drive? It's a lot less than many
might think. Although it depends on each person
and situation, here is some general information on
the problem.
The Blood Alcohol Concentration (BAC) of someone
who is drinking depends upon four things:

The amount of alcohol consumed

The drinker's body weight

The amount of food that is consumed before and
during drinking

The length of time it has taken the drinker to
consume the alcohol.
According to the American Medical Association, a
180
-lb. (82 kg) person who drinks three 12-ounce
(355 ml) bottles of beer in an hour will end up with a
BAC of about 0.06 percent. The person would reach the
same BAC by drinking three 4
-ounce (120 ml) glasses
of wine or three mixed drinks if each had 1
-1/2 ounces
(45 ml) of a liquor like whiskey, gin or vodka.

twice a year for wear or cracking. See ªWiper Blade
