81 Safety and Security
Occupant safety
A statement by the child restraint manu-
facturer of compliance with these stan-
dards can be found on the instruction label
on the restraint and in the instruction
manual provided with the restraint.
When using any infant, or toddler restraint,
or booster seat, be sure to carefully read
and follow all manufacturer’s instructions
for installation and use.
Please read and observe warning labels
affixed to inside of the vehicle and to infant
or child restraints.
Warning!G
Children 12 years old and under must be
seated and properly secured in an appropri-
ate infant or child restraint recommended
for the size and weight of the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt fully
in accordance with the child seat manufac-
turer’s instructions.
Occupants, especially children, should
never place their bodies or lean their heads
in the area of the door where the
head-thorax air bag inflates. This could
result in serious injuries or death should the
head-thorax air bag be triggered. Always sit
as upright as possible, properly use the seat
belt and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of
the child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when you place a
child in the passenger seat:
Your vehicle is equipped with air bag
technology designed to turn off the pas-
senger front air bag in your vehicle when
the OCS senses the weight of a typical
12-month-old child or less along with
the weight of a standard appropriate
child restraint on the front passenger
seat.
A child in a rear-facing child restraint on
the passenger seat will be seriously
injured or even killed if the passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology
installed in your vehicle.
If you install a rear-facing child restraint
on the passenger seat, make sure that
the 75indicator lamp is
illuminated, indicating that the passen-
ger front air bag is deactivated. Should
the 75 indicator lamp not
illuminate or go out while the restraint is
installed, please check installation.
Periodically check the 75
indicator lamp while driving to make
sure the 75indicator lamp
is illuminated. If the 75
indicator lamp goes out or remains out,
do not transport a child on the passen-
ger seat until the system has been
repaired. A child in a rear-facing child
restraint on the passenger seat will be
seriously injured or even killed if the
passenger front air bag inflates.
82 Safety and Security
Occupant safety
If you place a child in a forward-facing
child restraint on the passenger seat,
move the seat as far back as possible,
use the proper child restraint recom-
mended for the age, size and weight of
the child, and secure child restraint with
the vehicle’s seat belt according to the
child seat manufacturer’s instructions.
For children larger than the typical
12-month-old child, the passenger front
air bag may or may not be activated
(
page 72).
Warning!G
Infants and small children should never
share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.
Warning!G
Children too big for a toddler restraint must
ride in seats using regular seat belts.
Position the shoulder belt across chest and
shoulder, not face or neck. A booster seat
may be necessary to achieve proper seat
belt positioning for children over 41 lbs until
they reach a height where a lap/shoulder
belt fits properly without a booster.
When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the
vehicle, even if the children are secured in a
child restraint system. Unsupervised
children in a child restraint system may use
vehicle equipment and may cause an
accident and/or serious personal injury.
107 Controls in detail
Memory function*
Memory function*
Prior to operating the vehicle, the driver
should check and adjust the seat height,
seat position fore and aft, and seat back-
rest angle if necessary, to ensure adequate
control, reach and comfort. The head re-
straint should also be adjusted for proper
height. See also the section on air bags
(
page 66) for proper seat positioning.
In addition, adjust the steering wheel to
ensure adequate control, reach, operation
and comfort. Both the interior and exterior
rear view mirrors should be adjusted for
adequate rear vision.
Fasten seat belts. Infants and small
children should be seated in an appropri-
ate infant or child restraint system which is
properly secured by a lap-shoulder belt
and that complies with U.S. Federal Motor
Vehicle Safety Standards 213 and 255
and Canadian Motor Vehicle Safety
Standards 213 and 210.2.With the memory function you can store up
to three different configurations.
Each store position on the driver’s side
includes the following settings:

319 Operation
Tires and wheels
General:
Depending on the design standards used,
the tire size molded into the sidewall may
have no letter or a letter preceding the tire
size designation.
No letter preceding the size designation
(as illustrated above): Passenger car tire
based on European design standards.
Letter “P” preceding the size designation:
Passenger car tire based on U.S. design
standards.
Letter “LT” preceding the size designation:
Light Truck tire based on U.S. design
standards.
Letter “T” preceding the size designation:
Temporary spare tires which are high
pressure compact spares designed for
temporary emergency use only. Tire width
The tire width1 (
page 318) indicates
the nominal tire width in mm.
Aspect ratio
The aspect ratio2 (
page 318) is the
dimensional relationship between tire
section height and section width and is
expressed in percentage. The aspect ratio
is arrived at by dividing section height by
section width.
Tire code
The tire code3 (
page 318) indicates
the tire construction type. The “R” stands
for radial tire type. Letter “D” means diag-
onal or bias ply construction; letter “B”
means belted-bias ply construction.
At the tire manufacturer’s option, any tire
with a speed capability above 149 mph
(240 km/h) can include a “ZR” in the size
designation (for example: 245/40 ZR 18).
For additional information, see “Tire speed
rating” (
page 320).Rim diameter
The rim diameter4 (
page 318) is the
diameter of the bead seat, not the
diameter of the rim edge. Rim diameter is
indicated in inches (in).
Tire load rating
The tire load rating5 (
page 318) is a
numerical code associated with the
maximum load a tire can support.
For example, a load rating of 91 corre-
sponds to a maximum load of 1 356 lbs
(615 kg) the tire is designed to support.
See also “Maximum tire load”
(
page 324) where the maximum load as-
sociated with the load index is indicated in
kilograms and lbs.
339 Operation
Vehicle care
Engine cleaning
Prior to cleaning the engine compartment,
make sure to protect electrical compo-
nents and connectors from the intrusion of
water and cleaning agents.
Corrosion protection, such as
MB Anticorrosion Wax should be applied to
the engine compartment after every en-
gine cleaning. Before applying, all control
linkage bushings and joints should be
lubricated. The poly-V-belt and all pulleys
should be protected from any wax.
Vehicle washing
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the vehicle underbody, do
not forget to clean the inner sides of the
wheels.Hand-wash
Do not use hot water or wash your vehicle
in direct sunlight.
Use only a mild car wash detergent,
such as Mercedes-Benz approved Car
Shampoo.
Thoroughly spray the vehicle with a
diffused 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
climate control (
page 178) or auto-
matic climate control (
page 189) to
air recirculation mode.
If the vehicle is very dirty, prewash it be-
fore running it through the automatic car
wash.
!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 to0 (
page 56). Otherwise, 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
damage to the mirrors.
343 Operation
Vehicle care
Seat belts
Use only clear, lukewarm water and
soap.
Upholstery
Using aftermarket seat covers or wearing
clothing that have the tendency to give off
coloring (e.g. when wet, etc.) may cause
the upholstery to become permanently
discolored. By lining the seats with a
proper intermediate cover,
contact-discoloration will be prevented.Leather upholstery
Please note that leather upholstery is a
natural product and is therefore subject
to a natural aging process. Leather
upholstery may also react to certain
ambient influences such as high humidity
or high temperature by showing wrinkles
for example.
Wipe leather upholstery with a damp
cloth and dry thoroughly or clean with
Mercedes-Benz approved Leather
Care.Exercise particular care when cleaning
perforated leather as its underside should
not become wet.
Wood trims
Dampen cloth using water and use
damp cloth to clean wood trims in your
vehicle.
!The seat belts must not be treated with
chemical cleaning agents. Do not dry the seat
belts at temperatures above 176°F (80°C) or in
direct sunlight.
Warning!G
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
Warning!G
Only use seat covers which have been
tested and approved by Mercedes-Benz for
your vehicle model. Using other seat covers
may interfere with or prevent the deploy-
ment of the head-thorax air bags. Contact
an authorized Mercedes-Benz Center for
availability.
!Wipe with light pressure, to avoid damage to
the upholstery.
!Do not use solvents like tar remover or
wheel cleaner nor polishes or waxes as these
may be abrasive.
