11 Introduction
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.

159 Controls in detail
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).
