The climate control system is operational
whenever the engine is running. You can
operate the climate control system in either
the automatic or manual mode. The system
cools or heats the interior depending on the
selected interior temperature.
It can only function optimally when you are
driving with the windows and the retractable
hardtop closed.
Nearly all dust particles, pollutants and odors
are filtered out before outside air enters the
passenger compartment through the air
distribution system.GWarning!
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at an authorized Mercedes-Benz
Center.
The air conditioning will not engage (no
cooling) if the A/C mode ( Y page 150) is
deactivated.
GWarning!
Follow the recommended settings for heating
and cooling given on the following pages.
Otherwise the windows could fog up,
impairing visibility and endangering you and
others.XKeep 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 objects on the
air flow-through exhaust slots below the rear
window.
i If the vehicle interior is hot, ventilate the
interior before driving off. The climate
control will then adjust the interior
temperature to the set value much faster.
Deactivating the climate control
system
GWarning!
When the climate control system is
deactivated, the outside air supply and
circulation are also deactivated. Only choose
this setting for a short time when the

Programming tips
If you are having difficulty programming the
integrated remote control, here are some
helpful tips:
R Check the frequency of hand-held remote
control 0086 (typically located on the reverse
side of the remote). The integrated remote
control is compatible with radio-frequency
devices operating between 280-390 MHz.
R Put a new battery in hand-held remote
control 0086. This will increase the likelihood
of the hand-held remote control sending a
stronger and more accurate signal to the
integrated remote control.
R While performing step 3, hold hand-held
remote control 0086 at different lengths and
angles from the signal transmitter button
( 0047 , 008A or 0088) you are programming.
Attempt varying angles at the distance of 2
to 12 inches (5 to 30 cm) away or the same
angle at varying distances.
R If another hand-held remote control is
available for the same device, try the
programming steps again using that other
hand-held remote control. Make sure new
batteries are in the hand-held remote
control before beginning the procedure.
R Straighten the antenna wire from the
garage door opener assembly. This may
help improve transmitting and/or receiving
signals.
i Certain types of garage door openers are
incompatible with the integrated remote
control. If you should experience further
difficulties with programming the
integrated remote control, contact an
authorized Mercedes-Benz Center, or call
the Mercedes-Benz Customer Assistance
Center (USA only) at
1-800-FOR-MERCedes (1-800-367-6372),
or the HomeLink ®

Recommended tire inflation pressureGWarning!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are
more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver’s door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading the tires can also result
in handling or steering problems, or brake
failure.
Your vehicle is equipped with the Tire and
Loading Information placard located on the
driver’s door B-pillar (Y page 193).
The tire inflation pressure should be checked
regularly. Only adjust the tire inflation
pressure on cold tires. The tires can be
considered cold if the vehicle has been
parked for at least 3 hours or driven less than
1 mile (1.6 km). Depending on the ambient
temperature, the driving speed and the tire
load, the tire temperature changes. When the
tire temperature changes by 18‡ (10†), the
tire inflation pressure will change by
approximately 1.5 psi (0.1 bar). Keep this in
mind when checking tire inflation pressure on
warm tires and adjust the tire pressure only
if the tire inflation pressure is too low for the
current operating conditions. If you check the
tire inflation pressure when the tires are
warm, the reading will be higher than the cold
reading. This is normal. Do not let air out to
match the specified cold tire inflation
pressure. Otherwise, the tire will be
underinflated.
Follow recommended cold tire inflation
pressures listed on Tire and Loading
Information placard on the driver’s door
B-pillar.
Keeping the tires properly inflated provides
the best handling, tread life and riding
comfort.
In addition to the Tire and Loading
Information placard on the driver’s door
B-pillar, also consult the tire inflation
pressure label on the inside of the filler flap
for any additional information pertaining to
special driving situations. For more
information, see “Important notes on tire
inflation pressure” (Y page 188).
iData shown on Tire and Loading
Information placard example are for
illustration purposes only. Tire data are
specific to each vehicle and may vary from
data shown in the following illustration.
Refer to Tire and Loading Information
placard on vehicle for actual data specific
to your vehicle.
The Tire and Loading Information placard lists
the recommended cold tire inflation
pressures \000F for maximum loaded vehicle
weight. The tire inflation pressures listed
apply to the tires installed as original
equipment.
