Road Engineering package)
Important safety notes Level control adapts the vehicle level automati-
cally to the current operating and driving situa-
tion. This results in reduced fuel consumption
and improved handling.
Make changes to the vehicle level while the
vehicle is in motion. This enables the vehicle to adjust to the new level as quickly as possible.
The vehicle level may change visibly if you park
the vehicle and the outside temperature
changes. If the temperature drops, the vehicle
level is lower; with an increase in temperature,
the vehicle level rises.
If you unlock the vehicle or open a door, the
vehicle begins to compensate for load discrep-
ancies while still parked. However, for signifi-
cant level changes, such as after the vehicle has
been stationary for a long period, the engine
must be on. For safety reasons, the vehicle is
only lowered when the doors are closed. Low- ering is interrupted if a door is opened, and it
continues once the door has been closed.

WARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is a risk of
injury.
Make sure no one is underneath the vehicle or in the immediate vicinity of the wheel arches
when the vehicle is being lowered. G
WARNING
When you drive with the vehicle raised, the
driving characteristics could be impaired by
the vehicle's raised center of gravity. The vehi- cle could rollover more easily, for example on
a bend. There is a risk of an accident.
Always select as low a vehicle level as possi-
ble and adjust your driving style. G
WARNING
When you drive with the chassis lowered or
raised, the vehicle's braking and driving char-
acteristics can be significantly impaired. You
could also exceed the permissible vehicle
height if the chassis is raised. There is a risk of an accident.
Adjust the vehicle level before pulling away. G
WARNING
Due to the high center of gravity, the vehicle
may start to skid and roll over in the event of
an abrupt steering maneuver and/or when
the vehicle's speed is not adapted to the road conditions. There is a risk of an accident.
Always adapt your speed and driving style to
the vehicle's driving characteristics and to the prevailing road and weather conditions.
! When driving on extremely rough terrain,
select a high vehicle level in good time. Make
sure there is always sufficient ground clear-
ance. You will otherwise damage the vehicle. Driving systems

Avoid tire pressures that are too low in all the
tires, including the spare wheel.
Underinflated tires may:
R overheat, leading to tire defects
R adversely affect handling
R wear excessively and/or unevenly
R have an adverse effect on fuel consumption
Overinflated tires G
WARNING
Tires with excessively high pressure can burst
because they are damaged more easily by
road debris, potholes etc. In addition, they
also suffer from irregular wear, which can
severely impair the braking properties and the driving characteristics. There is a risk of an
accident.
Avoid tire pressures that are too high in all the
tires, including the spare wheel.
Overinflated tires may: R increase the braking distance
R adversely affect handling
R wear excessively and/or unevenly
R have an adverse effect on ride comfort
R be more susceptible to damage
Maximum tire pressures 0043
Example: maximum permissible tire pres-
sure
Never exceed the maximum permissible tire
inflation pressure. Always observe the recom-
mended tire pressure for your vehicle when
adjusting the tire pressure (Y page 354).i
The actual values for tires are vehicle-spe-
cific and may deviate from the values in the
illustration. Checking the tire pressures
Important safety notes Observe the notes on tire pressure
(Y
page 354).
Information on air pressure for the tires on your vehicle can be found:
R on the Tire and Loading Information placard
on the B-pillar on the driver's side
R in the tire pressure table in the fuel filler flap
R in the "Tire pressure" section
Checking tire pressures manually To determine and set the correct tire pressure,
proceed as follows:
X Remove the valve cap of the tire that is to be
checked.
X Press the tire pressure gage securely onto the
valve.
X Read the tire pressure and compare it to the
recommended value on the Tire and Loading
Information placard or the tire pressure table
(Y page 354).
X If the tire pressure is too low, increase the tire
pressure to the recommended value.
X If the tire pressure is too high, release air. To
do so, press down the metal pin in the valve,
using the tip of a pen for example. Then check the tire pressure again using the tire pressure
checker.
X Screw the valve cap onto the valve.
X Repeat these steps for the other tires. Tire pressure loss warning system
General notes While the vehicle is in motion, the tire pressure
loss warning system monitors the set tire pres-
sure using the rotational speed of the wheels.
This enables the system to detect significant
pressure loss in a tire. If the speed of rotation of
a wheel changes as a result of a loss of pressure, Tire pressure

the defective wheel has been replaced with a
new wheel.
Vehicles with a tire pressure control sys-
tem: all installed wheels must be equipped with
functioning sensors. Wheel and tire combinations
Information regarding permitted wheel/tire
combinations can be found at an authorized
Mercedes-Benz Center.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tires and wheels
which have been approved by Mercedes-Benz specifically for your vehicle.
These tires have been specially adapted for
use with the control systems, such as ABS or
ESP ®
, and are marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(tires featuring run-flat characteristics)
R MO1 = Mercedes-Benz Original (only cer-
tain AMG tires)
Mercedes-Benz Original Extended tires may
only be used on wheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz. Certain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with a load, tire dimension variations
could cause the tires to come into contact
with the bodywork and axle components. This
could result in damage to the tires or the vehi- cle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tires, wheels or
accessories other than those tested and
approved.
Information on tires, wheels and approved
combinations can be obtained from any quali- fied specialist workshop.
! Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz, since previ-
ous damage cannot always be detected on
retreaded tires. As a result, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tires are mounted. Do not mount used tires if you have no information about their previous
usage.
The recommended pressures for various oper-
ating conditions can be found:
R on the Tire and Loading Information placard
on the B-pillar on the driver's side
R in the tire pressure table in the fuel filler flap
Observe the notes on recommended tire pres-
sures under various operating conditions
(Y page 354).
Check tire pressures regularly, and only when
the tires are cold. Comply with the maintenance recommendations of the tire manufacturer in
the vehicle document wallet.
Notes on the vehicle equipment – always equip
the vehicle:
R with tires of the same size on a given axle (left
and right)
R with the same type of tires at a given time
(summer tires, winter tires, MOExtended
tires)
i Vehicles equipped with MOExtended tires
are not equipped with a TIREFIT kit at the fac- tory. It is therefore recommended that you
additionally equip your vehicle with a TIREFIT
kit if you mount tires that do not feature run- flat properties, e.g. winter tires. A TIREFIT kit
may be obtained from a qualified specialist
workshop. Emergency spare wheel
Important safety notes
G
WARNING
The wheel or tire size as well as the tire type of the spare wheel or emergency spare wheel
and the wheel to be replaced may differ.
Mounting an emergency spare wheel may
severely impair the driving characteristics.
There is a risk of an accident.

system.
! Do not use the following:
R Gasoline with more than 10% ethanol
R E100 (100% ethanol)
R Gasoline with methanol
R M100 (100% methanol)
R Gasoline with metalliferous additives
R Diesel
Do not mix such fuels with the fuel recom-
mended for your vehicle.
! To ensure the longevity and full perform-
ance of the engine, only premium-grade
unleaded gasoline must be used.
If standard unleaded gasoline is unavailable
and you have to refuel with unleaded gasoline of a lower grade, observe the following pre-
cautions:
R Only fill the fuel tank to half full with regular
unleaded gasoline and fill the rest with pre- mium-grade unleaded gasoline as soon as
possible.
R Do not drive at the maximum speed.
R Avoid sudden acceleration and engine
speeds over 3,000 rpm.
i For more information, please contact a
qualified specialist workshop or visit
http://www.mbusa.com (USA only).
As a temporary measure, if the recommended
fuel is not available, you may also use regular
unleaded gasoline with an octane rating of
87 AKI/91 RON. This may reduce engine per-
formance and increase fuel consumption. Avoid driving at full throttle and sudden acceleration.
Never refuel using gasoline with a lower AKI.
Information on refueling (Y page 151).
Additives ! Operating the engine with fuel additives
added later can lead to engine failure. Do not mix fuel additives with fuel. This does not
include additives for the removal and preven-
tion of residue buildup. gasoline must only be
mixed with additives recommended by
Mercedes-Benz. Comply with the instructions for use on the product label. More information
about recommended additives can be
obtained from any authorized Mercedes-Benz
Center. Mercedes-Benz recommends that you use bran-
ded fuels that have additives.
The fuel quality available in some countries maynot be sufficient. Residue could build up in the
fuel injection system as a result. In such cases, and in consultation with an authorized
Mercedes-Benz Center, the fuel may be mixed
with the cleaning additive recommended by
Mercedes-Benz. You must observe the notes
and mixing ratios specified on the container.
Diesel Fuel grade
G
WARNING
If you mix diesel fuel with gasoline, the flash
point is lower than that of pure diesel fuel.
When the engine is running, exhaust system
components could overheat without being
noticed. There is a risk of fire.
Never refuel with gasoline. Never mix gasoline with diesel fuel.
! Only use Ultra Low Sulfur Diesel (ULSD),
otherwise it may lead to increased wear and
damage to the fuel system, engine and
exhaust system.
! Do not use the following:
R gasoline
R diesel with a bio-diesel content greater
than 5% (e.g. B20)
R bio-diesel
R vegetable oil
R paraffin
R kerosene
R marine diesel
R heating oil
Do not mix such fuels with diesel fuel and do
not use any special additives. Otherwise,
engine damage may occur.
! In countries outside USA and Canada, only
use sulfur-free diesel with a sulfur content
under 50 ppm. Otherwise, the emission con-
trol system could be damaged.

and creating sparks. Switch off the ignition
before refueling and, if present, switch off the auxiliary heating. 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 with-
out delay.
R If fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
R Immediately change out of clothing which
has come into contact with fuel.
Flexible Fuel vehicles can be refueled with the
following fuel types:
R premium-grade unleaded gasoline
R E85 fuel
R a mixture of E85 fuel and premium-grade
unleaded gasoline
i Flexible Fuel vehicles can be recognized by
the Ethanol up to E85 sticker on the inside of
the fuel filler flap. Fuel consumption
The energy content of E85 fuel is less than that of the same amount of premium-grade gasoline.The amount of fuel consumed when operating
the vehicle with E85 fuel is therefore higher than
with premium-grade gasoline.
MaintenanceInform your authorized Mercedes-Benz Center
that you are operating or have operated the
vehicle with E85 fuel.
Low outside temperatures If the outside temperature is below 32 ‡(0 †),
the starting procedure can take noticeably lon-
ger when operating with E85 fuel.
E85 fuel is not suitable for use at outside tem-
peratures under -4 ‡ (-20 †). DEF
Important safety notes Comply with the important safety notes for ser-
vice products when handling DEF (Y page 383).
DEF is a water-soluble fluid for the exhaust gas
aftertreatment of diesel engines. It is:
R not poisonous
R colorless and odorless
R not flammable
When you open the DEF container, small
amounts of ammonia vapor may be released.
Ammonia vapors have a pungent odor and are
particularly irritating to the skin, to mucous
membranes and to the eyes. You may experi-
ence a burning sensation in your eyes, nose and throat. Coughing and watering of the eyes are
possible.
Do not inhale ammonia vapors. Fill the DEF tank
only in well-ventilated areas.
Low outside temperatures DEF freezes at a temperature of approximately
12
‡(-11 †). The vehicle is delivered from the
factory equipped with a DEF preheating system. Winter operation can thus be guaranteed even
at temperatures below 12 ‡ (-11 †). 386
