The system probably will say. to change .& d between ,3000 miles
(5000 km) and ,7500 *miles. (125OO km), but it may even sary to change it
before
3000 under very severe conditions. It all depends on .your drivirrg
pattims.
If it’s been 7500 miles (12500 km) it,always says to’ change the oil.
There are two.thingslhe system doesn?t do:
0 It can’t sense. heavy dust in the.places where you- drive. If you -drive in
a dusty area, you should change your
oil -every 3000 miles (5000 km)
or 3 months (whichever comes first), unless the display says to chinge
it even sooner than that.
I
It doesn’t check how much oil you have, so you’ll still have to check
for that. To see how, see “Engine Oil.’’ in the Index.
men You’ve Changed the Oil
When new oi€ is,put in, you’ll need .to reset.your.system. To: do it, display
the “OIL LIFE
.INDEX’’ by pressing the INFORMATION button. Then
press -and;hold the RESET buttons until the display shows “POO-OIL

Electronic Level .Control
This keeps your car level.
The ignition’has to be
“ON” for the level control to work. When,you turn
the ignition off, you may hear the level control exhausting. The,system
consists
of an electronic rear position sensor, a smalldectric air
compressor, and air adjustable
SI kabsorbers mounted on the rear of
the vehicle.
If the system has .a slight leak, the air compressor will run frequently for a
few seconds each time.
i For a massive air leak, the air ‘compressor will stay on for. approximately
7 minutes. You should see your.deal.er for service, but.you can keep

for a cooler setting and
the red button for a
warmer setting. The

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.
If it's warm outside and you need to cool the air, use the next choice.
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 turnea on, in either the AUTO’br..
ECON setting and the fan setting
is not on “HI”, a small amount of ah ::.
will flow through the defroster duct while- the system is waiting for the
engine coolant to warm up enough to provide heat. This prevents your
breath from fogging your windshield. As the coolant warms up, the
blower fan speed will gradually increase and air will flow from the heater
outlets, with some air bleed to the windshield to prevent fogging under
most normal conditions.
..
Manually Recirculate Inside Air
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
Push this button to divide the air between the windshield and the heater
ducts.
This is useful when fog appears on the windshield or side glass due
to a sudden rain or snowy conditions.
Fan Speeds
Push the (symbol) button
until “AUTO” is displayed on the screen. At this
I 1 setting, the fan speed is
controlled automatically.
If it is cold outside, the blower may not run in the maximum high fan
speed right away. The system checksthe temperature
of the coolant to
assure it is warm enough to provide heat. When the coolant is warm, the
153

Downloaded from www.Manualslib.com manuals search engine controler will allow the fan to ramp up to a higher speed. This prevents
cold air from blowing into the passenger compartment.
If you want the blower fan to run only at a fixed high speed, push the
(upper) button until you see
“HI” on the display.
If you want the fan speed to be automatic, but you like the fan speed to
be higher than the AUTO setting, just push the buttons until “HI/AUTO”
is shown
on the display.
If you want the blower to run only at a fixed low speed, push the (low)
button until
“LO” is shown on the display. I
If you want the fan speed to run lower than the “AUTO” setting, push the -
button until “AUTO LO” is shown on the display.
DEFROSTER
-1
Push this button to
remove fog
or frost from
the windshield.
This setting sends most
of the air flow to the windshield with only a small
amount to the
floor outlets. In some cold start conditions, the “AUTO”
blower fan speed may be limited until the cooling system warms up. This
is normal to prevent windshield fogging.
L I,
-
The fan speed will work automatically to maintain your requested interior
temperature.
If you need more air to your windshield, you should select a
higher fan speed.

\,
It will help a lot if you first clear any ice and snow from the hood and the -
air inlet (it’s between the hood and the windshield).
REAR DEFOGGER
-1 Push this button to turn
I I on the rear defogger.
With it,
your rear window and both outside rearview mirrors are heated.
The system will automatically shut off after
10 minutes. If further
defrosting is desired, simply push the button again.
