Your vehicle has been parked outside ~ver~~ight in 
cold weather (below 32  OF/ 0" C) and you  have  set 
the  driver temperature  at 73  OF  (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 your comfort 
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 vpical Hot Weather  Example: 
Your vehicle has Seen parked outside  all day  in  hot 
weather  (above 
70 OF/ 2 1 O C) and you  have  set  the 
driver temperature at 
73 "F (23 O C) and  have  selected 
the  AUTO  mode. The system will  automatically  adjust 
the temperature  output  to maximum  cooling.  The  blower 
will start at a low speed momentarily  to push  the  hot 
air to the  floor of the  vehicle  and then 
go to a higher 
blower 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 your comfort  set  temperature, 
the  fan  speed will  decrease and the temperature  output 
may  become  warmer.  The  air intake may shift  from 
recirculation  to  fresh  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).

Downloaded from www.Manualslib.com manuals search engine 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, some  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 this highway safety problem 
is  for people never to  drink alcohol and then  drive. But 
what 
if people do?  How much  is “too much”  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: 
0 The amount  of alcohol  consumed 
0 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 
(1 20 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.

Windshield  Wiper  Blade  Replacement 
It’s  a good idea to  clean  or replace the wiper  blade 
assembly every six months. For  the proper  windshield 
wiper blade length and type,  see “Replacement  Parts”  in 
the Index. 
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: 
I. Open  the  hood  to gain  access  to  the  windshield  wipers. 
2. Lift  the  wiper  arm  until it locks  into  a vertical  position.
