Lowering the vehicle
GWARNING
The wheels could come loose if the wheel
bolts or wheel nuts are not tightened to the
prescribed tightening torque. There is a risk
of an accident.
Ensure that the wheel bolts or wheel nuts
are tightened to the prescribed tightening
torque.
If you are not sure, do not move the vehicle.
Contact a qualified specialist workshop and
have the tightening torque checked immedi-
ately.
XPlace the ratchet wrench onto the hexagonnut of the jack so that the lettersABarevisible.
XTurn the ratchet wrench until the vehicle isonce again standing firmly on the ground.
XPlace the jack to one side.

which have been approved by Mercedes-Benz specifically for your vehicle.
These tires have been specially adapted foruse with the control systems, such as ABS
or ESP®, and are marked as follows:
RMO = Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended(tires featuring run-flat characteristics)
RMO1 = Mercedes-Benz Original (only cer-tain AMG tires)
Mercedes-Benz Original Extended tires mayonly be used on wheels that have been spe-cifically approved by Mercedes-Benz.
Only use tires, wheels or accessories testedand approved by Mercedes-Benz. Certaincharacteristics, e.g. handling, vehicle noiseemissions or fuel consumption, may other-wise be adversely affected. In addition,when driving with a load, tire dimension var-iations could cause the tires to come intocontact with the bodywork and axle compo-nents. This could result in damage to thetires or the vehicle.
Mercedes-Benz accepts no liability for dam-age resulting from the use of tires, wheelsor accessories other than those tested andapproved.
Information on tires, wheels and approvedcombinations can be obtained from anyqualified specialist workshop.
!Retreaded tires are neither tested nor rec-ommended by Mercedes-Benz, since previ-ous damage cannot always be detected onretreaded tires. As a result, Mercedes-Benzcannot guarantee vehicle safety if retreadedtires are mounted. Do not mount used tiresif you have no information about their previ-ous usage.
The recommended pressures for various oper-ating conditions can be found:
Ron the Tire and Loading Information placardon the B-pillar on the driver's side
Rin the tire pressure table in the fuel filler flap
Observe the notes on recommended tire pres-sures under various operating conditions(Ypage 307).
Check tire pressures regularly, and only whenthe tires are cold. Comply with the mainte-nance recommendations of the tire manufac-turer in the vehicle document wallet.
Notes on the vehicle equipment – alwaysequip the vehicle:
Rwith tires of the same size on a given axle(left and right)
Rwith the same type of tire (summer tires,MOExtended tires, winter tires)
Exception: it is permissible to install a differ-ent type or make in the event of a flat tire.Observe the "MOExtended tires (tires withrun-flat characteristics" section(Ypage 288).
Vehicles equipped with MOExtended tires arenot equipped with a TIREFIT kit at the factory.It is therefore recommended that you addition-ally equip your vehicle with a TIREFIT kit if youmount tires that do not feature run-flat proper-ties, e.g. winter tires. A TIREFIT kit may beobtained from a qualified specialist workshop.
Emergency spare wheel
Important safety notes
GWARNING
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 dif-
fer. Mounting an emergency spare wheel
may severely impair the driving characteris-
tics. There is a risk of an accident.
To avoid hazardous situations:
Radapt your driving style accordingly and
drive carefully.
Rnever mount more than one spare wheel
or emergency spare wheel that differs in
size.
Ronly use a spare wheel or emergency
spare wheel of a different size briefly.
Rdo not switch ESP®off.
Rhave a spare wheel or emergency spare
wheel of a different size replaced at the
nearest qualified specialist workshop.
Observe that the wheel and tire dimen-
sions as well as the tire type must be cor-
rect.
When using an emergency spare wheel orspare wheel of a different size, you must not

exceed the vehicle's maximum design speedof 50 mph (80 km/h).
You should regularly check the pressure of theemergency spare wheel, particularly prior tolong trips, and correct the pressure as neces-sary (Ypage 307). The value on the wheel isvalid.
Snow chains must not be mounted on emer-gency spare wheels.
General notes
You can ask for information regarding permit-ted emergency spare wheels at an authorizedMercedes-Benz Center.
An emergency spare wheel may also be moun-ted against the direction of rotation. Observethe time restriction on use as well as thespeed limitation specified on the emergencyspare wheel.
Replace the tires after six years at the latest,regardless of wear. This also applies to theemergency spare wheel.
Tire pressure loss warning system (Can-ada only):as long as you are driving with theemergency spare wheel mounted, the tirepressure loss warning system cannot functionreliably. Only restart the tire pressure losswarning system when the defective wheel hasbeen replaced with a new wheel.
Vehicles with tire pressure monitor (USAonly):after an emergency spare wheel hasbeen mounted, the system may still displaythe tire pressure of the removed wheel for afew minutes. The value displayed for themounted emergency spare wheel is not thesame as the current tire pressure of the emer-gency spare wheel.

Information regarding technical data
iThe data stated here specifically refers toa vehicle with standard equipment. Consultan authorized Mercedes-Benz Center for thedata for all vehicle variants and trim levels.
Vehicle electronics
Installing two-way radios and mobile
phones (RF transmitters)
GWARNING
The electromagnetic radiation from two-way
radios can interfere with the vehicle elec-
tronics if two-way radios are manipulated or
retrofitted incorrectly. This could jeopardize
the operating safety of the vehicle. There is
a risk of an accident.
You should have all work on electrical and
electronic components carried out at a
qualified specialist workshop.
GWARNING
If you incorrectly operate two-way radios in
the vehicle, the electromagnetic radiation
may interfere with the vehicle electronics,
for example if:
Rthe two-way radio is not connected to an
exterior antenna
Rthe exterior antenna is not correctly
mounted or is not low-reflection
This could jeopardize the operating safety of
the vehicle. There is a risk of an accident.
Have the low-reflection exterior antenna
installed at a qualified specialist workshop.
Always connect two-way radios to the low-
reflection exterior antenna when operating
in the vehicle.
!The operating permit may be invalidated ifthe instructions for installation and use oftwo-way radios are not observed.
In particular, the following requirementsmust be complied with:
Ronly approved wavebands may be used
Robserve the maximum permissible outputin these wavebands
Ronly approved antenna positions may beused
Excessive levels of electromagnetic radiationmay cause damage to your health and thehealth of others. Using an exterior antennatakes into account current scientific discus-sions relating to the possible health hazardsthat may result from electromagnetic fields.
