A Typical Cold Weather Example:
Your vehicle has been parked outside overnight in
cold weather (below 32
F/ 0
C) and you have set the
driver temperature at 73
F (23
C) and have selected
the AUTO mode. The system will automatically adjust
the temperature output to maximum heating. The fan
will start at a low speed. This is to avoid blowing cold
air into the vehicle. The length of the delay depends on
the amount of time since the engine was last started, the
outside temperature and the engine coolant temperature.
As the coolant warms up, the fan speed will gradually
increase. Air will flow to the floor with some air to
the windshield to prevent fogging under most
normal conditions.
As the interior of the vehicle warms up to the set
temperature, the fan speed will decrease and the
temperature output may become cooler. If the interior
temperature continues to warm up due to heating from
the sun or outside temperature increases, the system
may switch to other air delivery modes (typically defog
or bi
-level).A Typical Hot Weather Example:
The vehicle has been parked outside all day in hot
weather (above 80
F/ 27
C) and you have set the
driver temperature at 73
F (23
C) and have selected the
AUTO mode. The system will automatically adjust the
temperature output to maximum cooling. The fan will
start at a low speed momentarily to push the hot air to
the floor of the vehicle and then go to a higher fan speed
with cold airflow out of the instrument panel outlets.
A small amount of airflow will continue through the
lower ducts to cool the floor area.
The air intake may start in the recirculated mode for
maximum cooling performance. As the interior of the
vehicle cools down to the set temperature, the fan speed
will decrease and the temperature output may become
warmer. The air intake may shift from recirculation to
outside air mode. If the interior continues to cool due to a
decrease in the amount of heat the vehicle is absorbing
from the sun or a decrease in the outside temperature, the
system could switch to other air delivery modes (typically
bi-level or defog).

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, about 16,000 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.

Windshield Wiper
Blade Replacement
Windshield wiper blades should be inspected at least
twice a year for wear or cracking. See ªWiper Blade
Checkº in the index for more information.
Replacement blades come in different types and are
removed in different ways. For the proper type and
length, see ªNormal Maintenance Replacement Partsº
in the Index.
It's a good idea to clean or replace the wiper blade
assembly every six months.
NOTICE:
Use care when removing or installing a blade
assembly. Accidental bumping can cause the
arm to fall back and strike the windshield.
To remove the wiper blade assembly:
1. Open the hood to gain access to the windshield wipers.
2. Lift the wiper arm until it locks into a vertical position.

3. Press down on the blade assembly pivot locking
tab (C). Pull down on the blade assembly (A) to
release it from the wiper arm hook (F).
4. Remove the insert from the blade assembly (A).
The insert has two notches at one end that are locked
by the bottom claws of the blade assembly. At the
notched end, pull the insert from the blade assembly.
