gear (both forward and reverse) for
gentler starts. This does not apply if
full throttle is applied or gear
range1 is selected.
Traction and driving stability are im-
proved on icy roads.
Upshifts occur earlier even when you
give more gas. The engine then oper-
ates at lower rpms and the wheels are
less likely to spin.

lector lever positionR changes de-
pending on the program mode
selected (
W or

Information on the windshield wipers
(page 44) and for setting the rear view
mirrors (
page 35) is found in the “Get-
ting started” section.
Rear view mirror
Automatic antiglare rear view mirror
The reflection brightness of the exterior
rear view mirror on the driver’s side and
the inside rear view mirror will respond au-
tomatically to glare when
the ignition is switched on, and
incoming light from headlamps falls on
the sensor in the inside rear view mir-
ror.
The rear view mirror will not react if
reverse gear is engaged
the interior lighting is turned on
Warning!
G
The automatic antiglare function does not
react if incoming light is not aimed directly
at sensors in the inside rear view mirror.
The inside rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, if the wind screen is in-
stalled.
Glare can endanger you and others.Warning!
G
Exercise care when using the passenger
side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
side rear view mirror or glance over your
shoulder before changing lanes.
Warning!
G
In the case of an accident liquid electrolyte
may escape from the mirror housing if the
mirror glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.!Electrolyte drops coming into contact
with the vehicle paint finish can be
completely removed only while in the
liquid state by applying plenty of water.

Automatic climate control
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.
Setting the temperature
Use the temperature controls1 and7 to
separately adjust the air temperature on
each side of the passenger compartment.
You should raise or lower the temperature
setting in small increments, preferably
starting at 72°F (22°C). Increasing
Turn the outer adjustment ring slightly
to the right.
The automatic climate control system
will correspondingly adjust the interior
air temperature.
Decreasing
Turn the outer adjustment ring slightly
to the left.
The automatic climate control system
will correspondingly adjust the interior
air temperature.
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
iIf the vehicle interior is hot, ventilate
the interior before driving off.
Keep the air intake grille in front of the
windshield free of snow and debris.
When the retractable hardtop is closed,
do not obstruct air flow by placing ob-
jects on the air flow-through exhaust
slots below the rear window.
iWhen operating the climate control
system in automatic mode, you will
only rarely need to adjust the tempera-
ture, air volume and air distribution.
