64 Safety and SecurityOccupant safety
Emergency tensioning device (ETD), 
seat belt force limiter
The seat belts for the front and rear outer 
seats are equipped with emergency ten-
sioning devices and belt force limiters.
The ETD is designed to activate in the fol-
lowing cases when the seat belts are fas-
tened:
in frontal or rear-end impacts exceed-
ing a preset severity level 
in certain vehicle rollovers
if the restraint systems are operational 
and functioning correctly, see 
1indicator lamp (
page 56)
Never wear the shoulder belt under your 
arm, against your neck or off your shoul-
der. In a crash, your body would move 
too far forward. That would increase the 
chance of head and neck injuries. The 
belt would also apply too much force to 
the ribs or abdomen, which could se-
verely injure internal organs such as 
your liver or spleen.
Never wear belts over rigid or breakable 
objects in or on your clothing, such as 
eyeglasses, pens, SmartKeys etc., as 
these might cause injuries.
Position the lap belt as low as possible 
on your hips and not across the abdo-
men. If the belt is positioned across your 
abdomen, it could cause serious injuries 
in a crash.
Never use a seat belt for more than one 
person at a time. Do not fasten a seat 
belt around a person and another per-
son or other objects.
Belts should not be worn twisted. In a 
crash, you wouldn’t have the full width 
of the belt to manage impact forces. The 
twisted belt against your body could 
cause injuries.
Pregnant women should also use a 
lap-shoulder belt. The lap belt portion 
should be positioned as low as possible 
on the hips to avoid any possible pres-
sure on the abdomen.
Never place your feet on the instrument 
panel or on the seat. Always keep both 
feet on the floor in front of the seat.

304 OperationVehicle careEngine cleaning
Prior to cleaning the engine compartment, 
make sure to protect electrical compo-
nents and connectors from contact with 
water and cleaning agents.
Corrosion protection, such as MB Anticor-
rosion Wax should be applied to the engine 
compartment after every engine cleaning. 
Before applying, all control linkage bush-
ings and joints should be lubricated. The 
poly-V-belt and all pulleys should be pro-
tected from any wax. 
Vehicle washing
Do not use hot water or wash your vehicle 
in direct sunlight. Use only a mild car wash 
detergent, such as Mercedes-Benz ap-
proved 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 clear water and thoroughly dry 
with a chamois. Do not allow cleaning 
agents to dry on the finish.
Due to the width of the vehicle, fold in out-
side mirrors prior to running the vehicle 
through an automatic car wash to prevent 
damage to the mirrors.
In the winter, thoroughly remove all traces 
of road salt as soon as possible.
When washing the undercarriage, do not 
forget to clean the inner sides of the 
wheels.Ornamental moldings
For regular cleaning and care of very dirty 
chrome-plated parts, use a chrome clean-
er.
Headlamps, tail lamps, side markers, 
turn signal lenses
Use a mild car wash detergent, such as 
Mercedes-Benz approved Car Shampoo, 
with plenty of water.
To prevent scratches, never apply strong 
force and use only a soft, non-scratchy 
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth 
or sponge.
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of 
water, and a SmartKey with KEY-
LESS-GO* is in close proximity, i.e. 
within approximately 3 ft (approxi-
mately 1 m), the vehicle could be inad-
vertently locked or unlocked.

408 Technical dataConsumer information
Consumer informationThe following text is published as required 
of all manufacturers of passenger cars un-
der Title 49, Code of U.S. Federal Regula-
tions, Part 575 pursuant to the “National 
Traffic and Motor Vehicle Safety Act of 
1966”.Uniform tire quality grading
Quality grades can be found, where appli-
cable, on the tire sidewall between tread 
shoulder and maximum section width. For 
example:
All passenger car tires must conform to 
federal safety requirements in addition to 
these grades.Tread wear
The tread wear grade is a comparative rat-
ing based on the wear rate of the tire when 
tested under controlled conditions on a 
specified government test course. For ex-
ample, a tire graded 150 would wear one 
and one-half (1½) times as well on the gov-
ernment course as a tire graded 100. The 
relative performance of tires depends 
upon the actual conditions of their use, 
however, and may depart significantly 
from the norm due to variations in driving 
habits, service practices and differences in 
road characteristics and climate.Traction
The traction grades, from highest to low-
est, are AA, A, B, and C. Those grades rep-
resent the tire’s ability to stop on wet 
pavement as measured under controlled 
conditions on specified government test 
surfaces of asphalt and concrete. A tire 
marked C may have poor traction perfor-
mance.Tread wear

The traction grade assigned to this tire is 
based on straight ahead braking traction 
tests, and does not include acceleration, 
cornering, hydroplaning, or peak traction 
characteristics.
