This message will appear when your engine oil is approximately a quart
low. If this message is displayed, check the
oil and add as needed.
CHECK WASHER FLUID - 25
This message will appear for a few seconds indicating that you need
washer solvent.
CHANGE OIL SOON - 40
This message will appear when your engine oil is less than 10 percent or
the mileage since the last
oil change is more than 6750 miles.
CHANGE ENGINE OIL - 82
This means that the life of your engine oil has expired and it should be
changed immediately. See engine
oil and filter recommendations in the
Maintenance Schedule. After an
oil change, the Oil Life Index must be
reset. See “Oil Life Indicator” in the index
on how to reset it.
CRUISE ENGAGED - 43
This message will appear for a few seconds when you select a speed to
cruise at.
ENGINE COOLANT HOT - 44
This message will appear when your engine coolant temperature is over
126°C (259OF). To avoid added strain on a hot engine, turn off your
Climate Control system, and stop and allow your vehicle to idle until it
cools down or the message
is removed. If it does not cool down, turn off
your engine and have it serviced before driving it again. Severe engine
damage can result from an overheated engine. See “Engine Overheating”
in the Index.
ENGINE HOT - A/C COMPRESSOR OFF - 16
This message will appear when the Climate Control is in “Auto” or
“Defrost” and the engine coolant is hotter than the normal operating
temperature.
To avoid added strain on a hot engine the air conditioning
compressor is automatically turned
off. When that happens, air
conditioned air is not delivered.
If the coolant temperature returns to
normal, the
A/C operation returns to normal.

TRUNK OPEN - 24
This message indicates that your trunk is open when the ignition is ON.
VERY LOW REFRIGERANT A/C COMPRESSOR OFT - 12
This message means that the Air Conditioning System detects a
refrigerant level that is low enough to cause damage to the A/C
compressor. To avoid damage, the A/C compressor automatically turns
off and the Electronic Climate Control will automatically switch from
“AUTO” to “ECON” and remain there. Have your A/C system serviced
if
this message appears.
Speed Sensitive Steering (SSS)
This system varies the amount of steering effort proportionate to your
vehicle speed. Steering is easier at a lower speed for increased
maneuverability and parking ease.
As your vehicle speed increases, the
steering effort is also increased proportionately. At highway speeds the
amount
of steering effort is greatly increased to provide a manual like
steering feel for maximum control and enhanced vehicle stability.
Speed Sensitive Suspension
The Speed Sensitive Suspension automatically controls the ride of your
vehicle. The system controls damping forces in the shock absorbers and
struts in response to various speed and road conditions. There are three
dampening modes: Comfort, Normal and Firm. As the vehicle speed
increases, the firmness of the suspension increases. The system is in the
Comfort mode, for speeds less than
40 mph (65 km), normal mode for
speeds between 40 mph
(65 km) and’70 mph (110 km/h), and firm for
speeds greater than 70 mph
(1 10 km/h). The system also stiffens damping
during hard acceleration, braking and cornering for increased control.
The Speed Sensing Suspension controller is a computer used to control
and monitor the system. The computer receives inputs from acceleration
and determines optimum mode strut valving
(or suspension stiffness) for
your current operating conditions. The computer also receives feedback

-I
Your vehicle has strategically placed electronic sensors, that feed
information to the vehicle’s computer systems. Your vehicle can control
the ventilation, heating, and air conditioning automatically year round.
The outside temperature, inside temperature setting, fan speeds, and the
ECC selection are displayed
on a digital screen.
OFF: Nothing is on, but air will flow through your vehicle if you’re
moving. The system
will try to keep the air at the selected temperature,
but it might not be able to maintain it
if it’s hot, or cold, outside.
“OUTSIDE” Temperature: The outside temperature is always displayed
when your vehicle is running. You can change it from Celsius to
Fahrenheit by pushing the ENG/MET (English/Metric) button.

Downloaded from www.Manualslib.com manuals search engine Temperature
To select the
temperature
you want,
push the blue button
for a cooler setting and
the red button for a
warmer setting. The
temperature setting
will be displayed on
the digital screen.
You can select temperatures from
65’F (18°C) to 85°F (29’C). And, at
each end,
you may choose 60” F (16’C), for maximum cooling, and 90 ” F
(33 ’ C), for maximum heating. We recommend when first getting familiar
with your vehicle, select
75°F (24’C). You may find that your own
personal comfort requires a slightly higher or lower setting. Once you set
the temperature, the system will automatically maintain the
set
temperature.
ECON
With this setting it’s all automatic, but the air conditioning compressor
does not operate and it won’t remove humidity from the air. However,
the system will try to keep the air at the selected temperature. Use this
setting
in cold or cool weather to save fuel.
r
If it’s warm outside and you need to cool the air, use the “AUTO” setting.

Downloaded from www.Manualslib.com manuals search engine AUTO
With this setting, the air conditioning compressor cycles when needed to
cool the air and it’s all automatic. In cold weather when the system senses
- the need for heat, the air flow will be directed out the floor ducts. As the
interior temperature approaches the desired setting, the blower speed
will decrease and the air flow could be directed through the defroster and
floor ducts.
To maintain interior comfort, the air flow may move to the air
outlets and floor ducts (Bi-level). On bright sunny days
in cold weather,
the air
flow could even come out the A/C outlets to maintain comfort and
prevent stuffiness.

A/C Purge
- .. If your vehicle is sitting out on a hot day and you have it set on AUTO,
the air will first flow out the floor air ducts for a few seconds. That is
normal. This is to expel hot air in the air ducts.
As the air is cooled, the
__ flow will move through the A/C outlets. If you start your vehicle with the
fan setting on “HI” it will skip the
A/C Purge.
Cold Weather Purge
-- On cold days when your system is first turned on, in either the AUTO or
ECON setting and the fan setting is not on “HI”, a small amount of air
will flow through the defroster duct while the system is waiting for the
breath from fogging your windshield.
As the coolant warms up? the
blower speed will gradually increase and air will

I.
There may be times, when you don’t want air from the outside. To
recirculate the air from the inside only, in either “AUTO” or “ECON”
setting, just set the temperature to 60 F (16 C) and adjust your fan - speed, if the air quantity is too high.
DEFOG
c_ Push this button to divide the air between the windshield and the heater
ducts. This is Lseful when fog appears on the windshield or side glass due
to a sudden rainy or snowy condition.
