Make sure that the ignition is switched
on or the relevant door is open and the
SmartKey is inserted in the starter
switch.
!Prior to operating the vehicle, the driv-
er should check and adjust the seat
height, seat position fore and aft, and
seat backrest angle if necessary, to en-
sure adequate control, reach and com-
fort. The head restraint should also be
adjusted for proper height. Also see
“Airbag” section (
page 55) for proper
seat positioning.
In addition, adjust the steering wheel to
ensure adequate control, reach, opera-
tion and comfort. Both the inside and
outside rear view mirrors should be ad-
justed for adequate rear vision.
Fasten seat belts. Infants and small

When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents in the
footwell can be very hot or very cold (de-
pending on the set temperature). This may
cause burn or frostbite to unprotected skin
in the immediate area of the air vents. Al-
ways keep sufficient distance between un-
protected parts of the body and the footwell
air vents. If necessary, change the air flow
using the air distribution controls to direct
the air away from the footwell air vents
(page 161).
iFor draft-free ventilation, move the slid-
ers for the center air vents to the mid-
dle position.

Automatic climate control
Automatic climate control panel
The automatic climate control is operation-
al whenever the engine is running. You can
operate the climate control system in ei-
ther the automatic or manual mode. The
system cools or heats the interior depend-
ing on the selected interior temperature
and the current outside temperature.
Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
The air conditioning will not engage (no
cooling) if the AC
OFF
mode is selected
(
page 166).

for each electronic key before it is re-
moved from the starter switch or when
the vehicle is locked using the
KEYLESS-GO* card (
page 105).
If the vehicle interior is hot, ventilate
the interior before driving off.
Keep the air intake grille in front of the
windshield free of snow, leaves, sticks
and any other debris.
Do not obstruct air volume by placing
objects on the air volume-through ex-
