Auto defogging system
(if equipped)
Auto defogging reduces the possibil-
ity of fogging up the inside of the
windscreen by automatically sensing
the moisture on inside the wind-
screen.
The auto defogging system operates
when the heater or air conditioning is
on.
Information
The auto defogging system may not
operate normally, when the outside
temperature is below -10 °C.When the Auto Defogging
System operates, the indi-
cator will illuminate.
If high level of moisture are sensed in
the vehicle, the Auto Defogging
System will operate in the following
order:
Step 1 : Outside air position
Step 2 :Operating the air conditioning
Step 3 : Blowing air toward the wind-
screen
Step 4 : Increasing air flow toward
the windscreen
If the air conditioning is off or recircu-
lated air position is manually selected
whilst Auto Defogging System is ON,
the Auto Defogging System Indicator
will blink 3 times to signal that the
manual operation has been can-
celled.To cancel or reset the Auto Defogging
System
Press the front windscreen defroster
button for 3 seconds when the igni-
tion switch is in the ON position.When the Auto Defogging System is
cancelled, the ADS OFF symbol will
blink 3 times and the ADS OFF will
be displayed on the climate control
information screen.
When the Auto Defogging System is
reset, the ADS OFF symbol will blink
6 times without a signal.
Information
• When the air conditioning is turned
on by Auto defogging system, if you
try to turn off the air conditioning, the
indicator will blink 3 times and the air
conditioning will not be turned off.
• For efficiency, do not select recircu-
lated air position whilst the Auto
defogging system is operating.

off, start the vehicle as explained.
(refer to "Using the 12V Battery
Reset Switch")Jump starting
In the event vehicle still does not
have a functional 12V battery (check
if interior lights will not turn on) then
you can try a jump start to the engine
compartment jumper terminals using
a 12V booster pack or jumper cables
from another vehicle's 12V battery
according to the following instruc-
tions.1. Position the vehicles close enough
that the jumper cables will reach,
but do not allow the vehicles to
touch.
2. Avoid fans or any moving parts in
the engine compartment at all
times, even when the vehicles are
turned off.
3. Turn off all electrical devices such
as radios, lights, air conditioning,
etc. Put the vehicles in P (Park)
and set the parking brake. Turn
both vehicles OFF.
NOTICE

Jump starting can be danger-
ous if done incorrectly. Follow
the jump starting procedure in
this section to avoid serious
injury or damage to your vehi-
cle. If in doubt about how to
properly jump start your vehi-
cle, we strongly recommend
that you have a service techni-
