Operator’s Manual
Important notice for California retail
buyers and lessees of Mercedes-Benz automobiles
Under California law you may be entitled to
a replacement of your vehicle or a refund
of the purchase price or lease price, if
Mercedes-Benz USA, LLC and / or its au-
thorized repair or service facilities fail to fix
one or more substantial defects or mal-
functions in the vehicle that are covered by
its express warranty after a reasonable
number of repair attempts. During the pe-
riod of 18 months from original delivery of
the vehicle or the accumulation of
18,000 miles (approx. 29,000 km) on the
odometer of the vehicle, whichever occurs
first, a reasonable number of repair at-
tempts is presumed for a retail buyer or
lessee if one or more of the following oc-
curs: (1) the same substantial defect or mal-
function results in a condition that is
likely to cause death or serious bodily
injury if the vehicle is driven, that de-
fect or malfunction has been subject to
repair two or more times, and you have
directly notified Mercedes-Benz USA,
LLC in writing of the need for its repair,
(2) the same substantial defect or mal-
function of a less serious nature than
category (1) has been subject to repair
four or more times and you have direct-
ly notified us in writing of the need for
its repair, or(3) the vehicle is out of service by reason
of repair of the same or different sub-
stantial defects or malfunctions for a
cumulative total of more than
30 calender days. Written notification
should be sent to us, not a dealer, at
Mercedes-Benz USA, LLC, Customer
Assistance Center, One Mercedes
Drive, Montvale, NJ 07645-0350.

42 Getting startedDrivingProper use of seat belts

Do not twist the belt when fastening.


Adjust seat belt so that the shoulder
portion is located as close as possible
to the middle of the shoulder (it should
not touch the neck or pass under the
arm).


Position the lap belt as low as possible
on your hips (over hip joint) and not
across the abdomen.


Place the seat backrest in a nearly up-
right position.


Never use a seat belt for more than one
person at a time.


Do not fasten a seat belt around a per-
son and another object at the same
time.


Check your seat belt during travel to
ensure that it is properly positioned.


Ensure that the seat belt is always fit-
ted snugly. You should avoid wearing
bulky clothing, such as winter coats,
when traveling in the vehicle.
Starting the engine
Warning!
G
Do not pass belts over sharp edges. They
could tear.
Do not allow the belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the belts.
Damaged seat belts or belts that were highly
stressed in an accident must be replaced by
an authorized Mercedes-Benz Center.
Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive with at least one window
fully open.

176 Controls in detailAutomatic climate controlThe 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 economy mode AC
OFF
is se-
lected (
page 184).
Warning!
G
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 178).
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.
iThe current climate control settings
(ON/OFF, temperature, air volume, ac-
tivated charcoal filter, etc.) are stored
for each SmartKey before it is removed
from the starter switch or when the ve-
hicle is locked using the KEYLESS-GO*
card (if so equipped) (
page 100).
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 and debris.
Do not obstruct air volume by placing
objects on the air volume-through ex-
haust slots below the rear window.

178 Controls in detailAutomatic climate controlAdjusting air distribution

Automatic climate control
Deactivating
Press button
O
(page 175).
The indicator lamp on the button goes
out.The air recirculation mode is deactivated
automatically:


after five minutes if the outside temper-
ature is below approximately 41°F
(5 °C)


after five minutes if the air conditioning
is turned off


after 30 minutes if the outside temper-
ature is above approximately 41°F
(5 °C)
At outside temperatures above 79°F
(26 °C) the system will not automatically
switch back to outside air. A quantity of
outside air is added after approximately
30 minutes.
iThe air recirculation mode is activated
automatically:

at high outside temperatures


if the concentration of carbon mon-
oxide and nitrogen oxide in the out-
side air increases, for example in a
tunnel.
Please note that the charcoal filter
must be activated (
page 182) for
the air recirculation mode to be ac-
tivated automatically.
If you have turned off the air condition-
ing (
page 184) or the outside tem-
perature is below 41°F (5°C), the air
recirculation mode will not switch on
automatically.

R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
Storage compartment ventilation
The storage compartment below the front
armrest (
page 225) has its own air vent.
Ventilation of the storage compartment
below the front armrest is possible only
when the climate control system is on. The
air volume depends on the setting of the
air distribution control, the air volume con-
trol, and the air vents in the dashboard.
The switch is located inside the storage
compartment in the front armrest
(
page 225).
Opening air vent

Push upper portion of switch.
Closing air vent

Push lower portion of switch.
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.
!If the AC
OFF
button on the automatic
climate control panel starts to blink,
the air conditioning may be losing re-
frigerant. The compressor was turned
off. The air conditioning cannot be
turned on again.

the nearest authorized Mercedes-Benz
Center.

196 Controls in detailDriving systems
Driving systemsThe driving systems of your vehicle are de-
scribed on the following pages:

Cruise control and Distronic*, with
which the vehicle can maintain a preset
speed


AIRMATIC adjusts the vehicle suspen-
sion characteristics automatically and
controls the vehicle level.


ABC* with vehicle level control sys-
tems, with which you can change vehi-
cle suspension characteristics


Parktronic*, which serves as a parking
assistant
For information on the BAS, ABS, and ESP
driving systems, see “Driving safety sys-
tems” (
page 76).
Cruise control
Cruise control automatically maintains the
speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time. You can set any speed
above 20 mph (30 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever found on the left-hand side of the
steering column (
page 20).
Warning!
G
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. The driver is and must remain at all
times responsible for the vehicle speed and
for safe brake operation.
Only use cruise control if the traffic, road
and weather conditions make it advisable to
travel at a steady speed.

The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.


The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.


Deactivate cruise control when driving
in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.
