Important safety notes
G
WARNING
Very hot or very cold air can flow from the air
vents. This could result in

burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air
outlets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windshield
and the hood free of blockages, such as ice,
snow or leaves.
R never cover the air vents or air intake grilles
in the vehicle interior.

seconds.
The zone currently selected appears in
compass display 0044(Y page 294).

If, after a few seconds, the display in
compass display 0044(Y page 294) changes
direction, the zone has been selected.
Calibrating the compass X
Make sure that there is sufficient space for
you to drive in a circle without impeding
traffic.
In order to calibrate the compass correctly,
do the following:
R calibrate the compass in the open and not
in the vicinity of steel structures or high-
voltage transmission lines.
R switch off electrical consumers such

as the
climate control, windshield wipers or rear
window defroster.
R close all doors and the tailgate.
X Switch on the ignition.
X Push a round pen into opening
0087(Y page 294) for approximately six
seconds, until symbol C is shown in
compass display 0044(Y page 294).
X Drive your vehicle in a full circle at
approximately 3 mph (5 km/h) to 6 mph
(10 km/h).
When the

calibration has successfully been
completed, the current direction is shown
in compass display 0044(Y page 294).Floormat on the driver's side

WARNING
Objects in the driver's footwell can restrict the
pedal travel or obstruct a depressed pedal. The operating and road safety of the vehicle
is jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the
pedals.

Do not use
loose floormats. X
Slide the seat backwards.
X To install: place the floormat in the
footwell.
X Press studs 0043 onto retainers 0044.
X To remove: pull the floormat off
retainers 0044.
X Remove the floormat. Features

Maximum tire load
0043 is the maximum
permissible weight for which the tire is
approved. Uniform Tire Quality Grading
Standards
Overview of Tire Quality Grading
Standards
Uniform Tire Quality Grading Standards are
U.S. government specifications. Their
purpose is to provide drivers with uniform
reliable information on tire
performance
data.
tire manufacturers have to grade tires using
three performance factors: tread wear 0043,
tire traction 0044 and heat resistance 0087. All
tires sold in North America are provided with
the corresponding quality class mark on the
sidewall of the tire, even though these
regulations do not apply to Canada.
i The actual values for tires are vehicle-
specific and may deviate from the values in
the illustration.
Where applicable, the tire grading
information can be found on the tire sidewall
between the tread shoulder and maximum
tire width.
For example: Treadwear Traction Temperature
200 AA A All passenger car tires must conform to the
statutory safety requirements in addition to
these grades.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate

of the tire when tested
under controlled conditions on a specified
U.S. government course. For example, a tire
graded 150 would wear one and one-half
times as well on the government 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 conditions. Traction
G
WARNING
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.
The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades represent
the tire's ability to stop on a wet surface as
measured under controlled conditions on
specified government test surfaces of

asphalt
and concrete. A tire marked C may have poor
traction performance.
The safe speed on a wet, snow covered or icy
road is always lower than on dry road
surfaces.
You should pay special attention to road
conditions when temperatures are around
the freezing point.
Mercedes-Benz recommends a minimum
tread depth of 00CF in (4 mm) for all four winter
tires ( Y page 330) to maintain normal driving
characteristics in winter. Winter tires can 344

Important safety notes G
WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and
explosion. You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the
auxiliary

heating before
refueling. G
WARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that

fuel does not come
into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
R Wash away fuel from skin immediately
using soap and water.
R If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance
without delay.
R If fuel is swallowed, seek medical
assistance without delay. Do not induce
vomiting.
R Immediately change out of clothing which

Important safety notes G
WARNING
Windshield washer concentrate is highly
flammable. If it comes into contact with hot
engine components or the exhaust system it
could ignite. There is a risk of fire and injury.
Make sure that no windshield washer
concentrate is spilled next to the filler neck.
! Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or
MB WinterFit. Unsuitable washer fluid
could damage the plastic lenses of the
headlamps.
! Do not add distilled or
de-ionized water to
the washer fluid container. Otherwise, the
level sensor may be damaged.
! Only MB SummerFit and MB WinterFit
washer fluid should be mixed together. The
spray nozzles may otherwise become
blocked.
When handling washer fluid, observe the
important safety notes on service products
(Y page 365).
At temperatures above freezing:
X Fill the washer fluid reservoir with a mixture
of water and windshield washer fluid, e.g.
MB SummerFit.
X Add 1 part MB SummerFit to 100 parts
water.
At temperatures below freezing:
X Fill the washer fluid reservoir with a mixture
of water and washer fluid, e.g. MB
WinterFit. Adapt the mixing ratio to the outside
temperature.
