mshowing tire rotation for single and dual
tires
Single tires: if the tires are of identical
dimensions, you can rotate both wheels on
both the front and rear axles so that the tires'
original direction of rotation is maintained. On
unidirectional tires, an arrow on the sidewall
shows the prescribed direction of rotation of
the tire.
Twin rear tires: if the tires are of identical
dimensions, you can rotate the wheels on the
front axle and the inner wheels on the rear
axle in pairs such that the original direction of
tire rotation is retained. With unidirectional
tires, you may rotate the outside wheels at
the rear axle from one side to the other. Direction of rotation
Tires with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of hydroplaning. You will only gain these
benefits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tire indicates
its correct direction of rotation.
You may mount a spare wheel against the
direction of rotation. Observe the time
restriction on use as well as the speed
limitation specified on the spare wheel. Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the
tires from contact with oil, grease and fuel. Mounting

Vehicle preparation X
Stop the vehicle as far away as possible
from traffic and on a level, firm and non-slip
surface.
X If you rvehicle poses a risk to approaching
traffic, switch on the hazard warning lamps.
X Apply the parking brake.
X Turn the fron twheels to the straight-ahead
position.
X Move the selector lever of the automatic
transmission to position P.
X Switch off the engine.
X Passengers should leave the vehicle. Make
sure that the passengers are not
endangered as they do so.
X Make sure that no one is near the danger
area while the wheel is being changed.
Anyone who is not directly assisting in the
wheel change should, for example, stand
behind the barrier.
X Place the warning triangle or warning lamp
at a suitable distance.
Observe legal requirements.
X Secure the vehicle to prevent it from rolling
away.
i Observe the safety notes on parking in the
section on "Driving and parking"
(Y page 145).
X On level terrain: place chocks or other
suitable objects under the front and rear of
the wheel that is diagonally opposite the
wheel to be changed.
X On slight inclines: place chocks or other
suitable objects under the wheels on the
front and rear axles opposite the wheel to
be changed. Changing wheels
303Wheels and tires Z
Wheels with centering by wheel bolts:
X Vehicles with alloy wheels: take the short
wheel bolts that fit the steel spare wheel
out of the vehicle tool kit.
X Screw in the wheel bolts and tighten them
lightly.
For wheels with wheel nuts:
X Fron twheels with wheel nut covers: press
the wheel nut covers onto the wheel nuts.
X Screw in the three wheel nuts over the
fixing discs of the wheel nut cover.
X Turn the wheel so that the wheel bolts are
in the middle of the holes.
X Screw on the rest of the wheel nuts.
X Slightly tighten all the wheel nuts.
Lowering the vehicle G
WARNING
The wheels could work loose if the wheel nuts
and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
! Only use the jack pump lever middle rod
and the rod with the largest diameter as a
lug wrench extension. Only slide the middle
rod as far as it will go onto the lug wrench.
The rods may otherwise bend and be
distorted to such an extent that they can
no longer be used as a pump lever for the
jack. Tightening torque pattern
0005—0024
Wheel bolts or wheel nuts
X Using the pump lever, slowly turn the
lowering screw on the jack through
approximately one revolution and carefully
lower the vehicle (Y page 304).
X Put the jack aside.
X Pull the rod with the smallest diameter off
the pump lever.
The shortened pump lever serves as a lug
wrench extension.
X Starting with the middle rod, slide the lug
wrench extension as far as it will go onto
the lug wrench.
X Using the extended lug wrench, tighten the
wheel bolts evenly in a crosswise pattern in
the sequence indicated (0005 to0024).
Tighten the wheel bolts to the following
tightening torques:
R steel wheel 177 lb-ft(240 Nm)
R alloy wheel 133 lb-ft(180 Nm)
Tighten the wheel nuts to atightening
torque of 133 lb-ft (180 Nm).
X Push the piston on the hydraulic jac kin
again and close the pressure release
screw.
X Stow the jack and the rest of the vehicle
tools in the vehicle again.
i You can now install the hub caps on steel
wheels with wheel bolts. The installing
procedure depends on whether the hub cap
acts as a trim that covers the whole wheel,
or just covers the center. Changing wheels

R do not deactivate ESP ®
.
R have a spare wheel that differs from the
wheel that has been changed replaced at
the nearest qualified specialist workshop.
You must observe the correc twheel and
tire dimensions as well as the wheel type.
When using a spare wheel of a different size,
do not exceed the maximum speed of
80 km/h. General notes
! Check the spare wheel regularly to see
that it is secure and has the prescribed tire
pressure.
The procedure for mounting the spare wheel
is described in "Mounting awheel"
(Y page 303).
The following should be checked regularly,
particularly prior to long journeys:
R the tire pressure of the spare wheel, which
should then be corrected if necessary
(Y page 278).
R the fastenings of the spare wheel bracket.
The spare wheel is located in a spare wheel
bracket under the rear of the vehicle.
Replace the tires after 6years at the latest,
regardless of wear. This also applies to the
spare wheel.
i If you have mounted a spare wheel, the
tire pressure monitor (Y page 281) will not
function for this wheel. The spare wheel is
not equipped with a sensor for monitoring
tire pressure. Removing and installing the spare

d(DEF)
General notes !
Only use DEF in accordance with
ISO 22241. The exhaus tgas aftertreatment
system may otherwise be damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0.
Damage caused by the use of other
reducing agents will invalidat ethe New
Vehicle Limited Warranty.
! If DEF comes into contact with a painted
or aluminum surface, wash the surface off
immediately with plenty of water.
High ambient temperatures When opening the DEF tank filler cap at high
outside temperatures, ammonia vapors may
escape. Ammonia vapors have a pungent
odor and are particularly irritating for your
skin, respiratory organs and eyes. This may
result in burning eyes, nose and throat, as
well as coughing and watering eyes. Do not
inhale ammonia vapors.
If DEF in the DEF reservoir heats up to
temperatures above 122 ‡
(50†) foralong
period of time (e.g. due to direct sunlight),
ammonia vapors form.
Low ambient temperatures DEF freezes at a temperature of
approximately 12
‡(002711 †). The vehicle is
equipped with a DEF preheating system at the
factory .This ensures that the vehicle can be
operated in winter, even at temperatures
below 12 ‡(002711 †).
Additives and tap water !
Do not mix DEF with any additives and do
not dilute DEF with tap water. Otherwise,
the exhaust gas aftertreatment may be
damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0. Damage that arises through the use of
additives or tap water will invalidate the
New Vehicle Limited Warranty.
Storage !
Containers made of aluminum, copper,
coppe ralloys as well as unalloyed or
galvanized steel are not suitable for storing
DEF. If stored in these types of containers,
DE Fc ould cause constituents of these
metals to dissolve and cause irreparable
damage to the exhaust gas aftertreatment.
Damage caused by such impurities in the
DEFw ill invalidate the New Vehicle Limited
Warranty.
Only store DEF in containers made of high-
alloy Cr-Ni steel or Mo-Cr-Ni steel in
accordance with DIN EN 10 088-1/2/3 or
plastic containers made of polypropylene or
polyethylene.
Purity !
Impurities in DE F(e.g. caused by other
service products, cleaning agents, dust,
etc.) result in increased emissions,
malfunctions, catalytic converter damage
or engine damage.
The purity of DEFi s essential to prevent
malfunctions in the exhaust gas
aftertreatment.
If DEF is pumped out of the DEF tank, e.g.
during repair work, the same liquid must not
be used to refill the tank. Its purity is no longer
guaranteed.
Disposal Observe country-specific laws and
regulations when disposing of DEF.

Dispose of DEF in an environmentally
responsible manner.320
