194 Controls in detail4-zone automatic climate control
The climate control is a 4-zone intelligent
climate control system. Your vehicle interi-
or is divided into 4 zones.With the help of a sun sensor, the climate
control determines the relation of the sun
to the vehicle and automatically adjusts
the inside temperature for every individual
zone.
You can set the temperature for each of
the 4 zones separately.
The climate control is operational whenev-
er the engine is running. It cools the vehi-
cle’s interior according to the angle and
intensity of the sun’s rays, the outside tem-
perature and the selected temperature.
You can operate the climate control sys-
tem in either the automatic or manual
mode.
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 A/C mode (
page 203) is
deactivated.
Warning!
G
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold (depending on the set temperature).
This may cause burn or frostbite to unpro-
tected skin in the immediate area of the air
vents. Always keep sufficient distance be-
tween unprotected parts of the body and the
air vents. If necessary, use the air distribu-
tion controls (
page 192) or (
page 193)
to direct the air to air vents in the vehicle in-
terior that are not in the immediate area of
unprotected skin.

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.i
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before its
scheduled interval. A clogged filter will reduce
the air volume to the interior.
If the vehicle interior is hot, ventilate the interior
before driving off, see “Summer opening fea-
ture” (page 210). The climate control will then
adjust the interior temperature to the set value
much faster.
Keep the air intake grille in front of the wind-
shield free of snow and debris.
Do not obstruct air flow by placing objects on the
air flow-through exhaust slots below the rear
window.
Warning!
G
When the climate control is switched off, the
outside air supply and circulation are also
switched off. Only choose this setting for a
short time. Otherwise the windows could
fog up, impairing visibility and endangering
you and others.

A window or tilt/sliding sunroof will only re-
turn to its previous position if it has not been
moved to another position using the respective
window switch or tilt/sliding sunroof switch af-
ter it was closed with button,.
A window or tilt/sliding sunroof that has been
moved will remain in its current position if
button, is used to re-open the remaining
windows or tilt/sliding sunroof.

335 Operation
Vehicle care
Hand-wash
Do not use hot water or wash your vehicle
in direct sunlight. 
Only use a mild car wash detergent,
such as Mercedes-Benz approved Car
Shampoo.

Thoroughly spray the vehicle with a dif-
fused jet of water.
Direct only a very weak spray towards
the ventilation intake.

Use plenty of water and rinse the
sponge and chamois frequently.

Rinse with clean water and thoroughly
dry with a chamois.
Do not allow cleaning agents to dry on
the finish.Automatic car wash
You can have your car washed in an auto-
matic car wash from the start. Automatic
car washes without brushes are prefera-
ble.

To protect the filter system, switch the
automatic climate control to air recir-
culation mode (
page 192) or
(
page 193).
If the vehicle is very dirty, prewash it be-
fore running it through the automatic car
wash.Ornamental moldings
For regular cleaning and care of ornamen-
tal moldings, use a damp cloth.
!
Do not use scouring agents on these parts.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the vehicle.
Do not attempt to wipe the surface with a dry
cloth or sponge.
Otherwise you may scratch or damage the paint.
!
Do not clean your vehicle in an automatic
touchless car wash which uses caustic spray.
Otherwise the caustic spray will damage the
paint or ornamental moldings.
!
Make sure that the windshield wiper switch
is set to 0(
page 57). Otherwise, e.g. the rain
sensor could activate and cause the wipers to
move unintentionally. This may lead to vehicle
damage.
Due to the width of the vehicle, fold in exterior
rear view mirrors prior to running the vehicle
through an automatic car wash to prevent dam-
age to the mirrors.
i
After running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 337). This will prevent smears
and reduce wiping noise which can be caused by
residual wax on the windshield.
When leaving the car wash, make sure that the
mirrors are folded out. Otherwise they may vi-
brate.
!
Do not use chrome cleaner on ornamental
moldings. Although ornamental moldings may
have chrome appearance, they could be made of
anodized aluminum that will be damaged when
cleaned with chrome cleaner. Instead, use a
damp cloth to clean those ornamental moldings.
For very dirty ornamental moldings of which you
are sure are chrome-plated, use a chrome clean-
er. If in doubt whether an ornamental molding is
chrome-plated, contact an authorized
Mercedes-Benz Center.

suitability in our engines and durability for
our service intervals. Therefore, only use
approved engine oils and oil filters re-
quired for vehicles with Maintenance Sys-
tem (U.S. vehicles) or FSS PLUS (Canada
vehicles). For a listing of approved engine
oils and oil filters, refer to the Factory Ap-
proved Service Products pamphlet (USA
only), or contact an authorized
Mercedes-Benz Center.
Engine oil additivesAir conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil are used in the air condition-
ing system.
Brake fluid
Only brake fluid approved by
Mercedes-Benz is recommended. Your
authorized Mercedes-Benz Center will pro-
vide you with additional information.
!
Using engine oils and oil filters of specifica-
tion other than those expressly required for the
Maintenance System (U.S. vehicles) or
FSS PLUS (Canada vehicles), or changing of oil
and oil filter at change intervals longer than
those called for by the Maintenance System
(U.S. vehicles) or FSS PLUS (Canada vehicles)
will result in engine or emission control system
damage not covered by the Mercedes-Benz Lim-
ited Warranty.Please follow Maintenance System (U.S. vehi-
cles) or FSS PLUS (Canada vehicles) recommen-
dations for scheduled oil changes. Failure to do
so could result in engine or emission control sys-
tem damage not covered by the Mercedes-Benz
Limited Warranty.
!

They may damage the engine.
Damage or malfunctions resulting from blending
oil additives are not covered by the
Mercedes-Benz Limited Warranty.
!
Never use R-12 (CFC) or mineral-based lu-
bricating oil. Otherwise damage to the system
will occur.
Warning!
G
During vehicle operation, the boiling point of
the brake fluid is continuously reduced
through the absorption of moisture from the
atmosphere. Under extremely strenuous op-
erating conditions, this moisture content
can lead to the formation of bubbles in the
system, thus reducing the system’s efficien-
cy.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s Mainte-
nance Booklet for replacement interval.
