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 Front wheels with wheel nut covers: press
the wheel nut covers onto the wheel nuts.
X Screw in the three wheel nuts over the fix-
ing 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 dis-
torted to such an extent that they can no
longer be used as a pump lever for the jack. Tightening torque pattern
0043—0084
Wheel bolts or wheel nuts
X Using the pump lever, slowly turn the low-
ering screw on the jack through approx-
imately one revolution and carefully lower
the vehicle (Y page 309).
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 (0043 to0084).
Tighten the wheel bolts to the following
tightening torques:
R Steel wheel 177 lb-ft(240 Nm)
R Light-alloy wheel 133 lb-ft(180 Nm)
Tighten the wheel nuts to a tightening tor-
que of 133 lb-ft (180 Nm).
X Push the piston on the hydraulic jack in
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 pro-
cedure depends on whether the hub cap
acts as a trim that covers the whole wheel,
or just covers the center. 312
Changing wheelsWheels and tires

R
only use a spare wheel that differs from the
wheel to be replaced for a short time.
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 correct wheel 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 a wheel"
(Y page 308).
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 290).
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 6 years 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 293) will not
function for this wheel. The spare wheel is
not equipped with a sensor for monitoring
tire pressure. Removing and installing the spare

Consumption figures were found in the cur-
rently valid respective version:
R for vehicles from the Euro 5 standard
according to regulation (EC) no.
715/2007
R for vehicles from the Euro 6 standard
according to regulation (EC) no.
595/2009
Fuel consumption depends on:
R the vehicle version
R the style of driving
R the operating conditions
R the type or quality of the fuel used
The vehicle will use more fuel than usual in
the following situations:
R at very low outside temperatures
R in city traffic
R during short journeys
R on mountainous terrain
R when towing a trailer
To keep fuel consumption low, observe the
advice in the "Protection of the environment"
section (Y page 22).
The following components of the different
vehicle versions influence fuel consumption:
R tire sizes, tire tread, tire pressure, tire con-
dition
R body
R transmission ratios for the drive assem-
blies
R additional equipment (e.g. air-conditioning
system, auxiliary heating system).
For these reasons, the actual consumption
figures for your vehicle may deviate from the
consumption figures determined according
to EU Directive 80/1268/EEC.
Data concerning fuel consumption are
recorded in the on-board computer; use the
steering wheel buttons to call up the Trip
computer menu (Ypage 197). Diesel Exhaust Fluid (DEF) General notes
!
Only use DEF in accordance with
ISO 22241. The exhaust gas aftertreatment
system may otherwise be damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0.
Damage caused by the use of other reduc-
ing agents will invalidate the 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 heats up, e.g. in direct sunlight, in the
DEF supply reservoir for some time to over
122 ‡ (50 †), ammonia vapor will develop.
Low ambient temperatures
DEF freezes at a temperature of approx-
imately 12 ‡(00F811 †). The vehicle is equipped
with a DEF preheating system at the factory.
Winter operation is therefore also guaranteed
at temperatures under 12 ‡ (00F811 †).
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 addi-
tives or tap water will invalidate the New
Vehicle Limited Warranty. 324
