Correct use of theseat belts
GWARNING
USESEATBELTS PROPERLY
RSeat beltscan only work when used
properly. Never wear seat beltsinany other
way than as describedinthissection, as
that couldresult in serious injuries in the
event of an accident.
REachoccupantshould wear their seat belt
at all times, because seat belts help reduce
the likelihood of and potential severity of
injuries in accidents, including rollovers.
The integrated restraint system includes
SRS (driver front air bag, driver's side knee
bag, front-passenger front air bag, side
impact air bags, pelvis air bags, window
curtain air bags for the side windows),
EmergencyTensioning Devices, seat belt
force limiters, and front seat knee bolsters.
The system is designed to enhance the
protection offered to properly belted
occupants in certain frontal (front air bags,
driver's side knee bag and ETDs) and side
(side impact air bags, window curtain air
bags, and ETDs) impacts which exceed
preset deployment thresholds and in
certain rollovers (window curtain air bags
and ETDs).
RNever wear the shoulder belt under your
arm, across your neck or off your shoulder.
Inafrontal crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The seat
belt would also apply too much force to the
ribs or abdomen, which could severely
injure internal organs such as your liver or
spleen.
Adjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder. It should not
touch the neck.Never pass the shoulder
portion of the seat belt under your arm. For
this purpose, you can adjust the height of
the seat belt outlet.
RPosition the lap belt as low as possible on
your hips and not across the abdomen. If
the lap belt is positioned across your
abdomen, it could cause serious injuries in
acrash.
RNever wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, keys etc., as
these might cause injuries.
RMake sure the seat belt is alwaysfitted
snugly. Take special care of this when
wearing loose clothing.
RNever useaseat belt for more than one
person atatime. Do not fastenaseat belt
aroundaperson and another person or
other objects at the same time.
RSeat belts should not be worn twisted. In a
crash, you would not have the full width of
the seat belt to distributeimpact forces.
The twisted seat belt against yourbody
could cause injuries.
RPregnant women should also alwaysuse a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible on
the hips to avoid any possible pressure on
the abdomen.
RPlace the seat backrest inaposition that is
as upright as possible.
RCheck your seat belt during travel to make
sure it is properly positioned.
RNever place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
RWhen usingaseat belt to secure infant
restraints, toddler restraints, or children in
booster seats, alwaysfollow the child seat
manufacturer'sinstructions.
Fastening seat belts
GWARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommendthat children be

Narrow vehicles
DISTRONIC PLUS has not yet detected the
vehicle in frontonthe edge of the road,
because of its narrow width. The distance to
the vehicle in front will be too short.
Obstructions and stationary vehicles
DISTRONIC PLUS does not brake for
obstacles or stationary vehicles. If, for
example, the detected vehicle turnsacorner
and reveals an obstacle or stationary vehicle,
DISTRONIC PLUS will not brake for these.
Crossing vehicles
DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane.
Activating DISTRONIC PLUS at traffic lights
with crossing traffic, for example, could cause
your vehicle to pull away unintentionally.
HOLD function
General notes
The HOLD function can assist the driver in the
following situations:
Rwhen pulling away,especiallyonsteep
slopes
Rwhen maneuvering on steep slopes
Rwhen waiting in traffic
The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.

workshop.
When parking your vehicle,makesure that
thetires do notget deformed by the curb or
other obstacles. If it is necessary to drive over
curbs, speed humps or similar elevations, try
to do so slowly and at an obtuse angle.
Otherwise, the tires, particularly the
sidewalls, may be damaged.
Regular checking of wheels and tires
GWARNING
Damaged tires can cause tire inflation
pressure loss. Asaresult, you could lose
control of your vehicle. There isarisk of
accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
Regularly checkthe wheels and tires of your
vehicle for damage at least onceamonth, as
well as after driving off-road or on rough
roads. Damaged wheels can causealoss of
tire pressure. Pay particular attention to
damage such as:
Rcuts in the tires
Rpunctures
Rtears in the tires
Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width
of the tire (Ypage 335). If necessary, turn
the front wheels to full lock in order to inspect
the inner side of the tire surface.
All wheels must haveavalve cap to protect
the valve against dirt and moisture. Do not
mount anything onto the valve other than the
standard valve cap or other valve caps
approved by Mercedes-Benzfor your vehicle.
Do not use any other valve caps or systems,
e.g. tire pressure monitoring systems.
Regularly check the pressure of all the tires
particularly prior to long trips. Adjust the tire
pressure as necessary (Ypage 338).
Observe the notes on the emergencyspare
wheel (Ypage 367).
The service life of tires depends, among other
things, on the following factors:
RDrivingstyle
RTire pressure
RDistance covered
Important safety notes on the tire
tread
GWARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where
speed is not adapted to suit the driving
conditions. There isarisk of accident.
If the tire pressure is too high or too low, tires
may exhibit different levels of wear at
different locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
RSummer tires:in (3 mm)
RM+S tires:in (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached.

Even if youhavecalculatedthe totalcargo
carefully, youshouldstill make sure thatthe
gross vehicle weight rating and the gross axle

be found on the vehicle identification plate on
the B-pillar on the driver's side of the vehicle
(Ypage 345).
Permissible gross vehicle weight:the
gross weight of the vehicle, all passengers,
load and trailer load/noseweight (if
applicable) must not exceed the permissible
gross vehicle weight.
Gross axle weight rating:the maximum
permissible weight that can be carried by one
axle (front or rear axle).
To ensure that your vehicle does not exceed
the maximum permissible values (gross
vehicle weight and maximum gross axle
weight rating), have your loaded vehicle
(including driver, occupants, cargo, and full
trailer load if applicable) weighed on a
suitable vehicle weighbridge.

Uniform Tire Quality Grading
Standards
Overview of Tire Quality Grading
Standards
Uniform Tire Quality Grading Standards are
U.S. governmentspecifications. Their
purpose is to provide drivers with uniform
reliableinformation on tire performance data.
Tire manufacturers have to grade tires using
three performance factors:tread wear
grade,traction grade and$temperature
grade. These regulations do not apply to
Canada.Nevertheless, all tires sold in North
America are provided with the corresponding
quality grading markings on the sidewall of
the tire.
Where applicable, the tire grading
information can be found on the tire sidewall
between the tread shoulder and maximum
tire width.
