Adding engine oil
!Use only engine oils and oil filters that are
approved for vehiclesw ithaservice system. A
list of the engine oils and oil filters that have
been tested and approved in accordance with
Mercedes-Benz Specifications for Service
Products is available at any authorized
Mercedes-Benz Center.
The following cause engine failure or damage
to the exhaust system:
RUse of engine oils and oil filters that have
not been expressly approved for the service
system
RReplacement of engine oil and oil filter after
the replacement interval specifiedbyt he
service system has expired
RUse of engine oil additives
!Do not add too much oil. If the oil level is
above the "max" mark on the dipstick, too
much oil has been added. This can leadt o
damage to the engine or the catalytic con-
verter. Have excess oil siphoned off.
HEnvironmental note
When adding oil, take care not to spilla ny. If
oil enters the soil or waterways ,itisharmful to
the environment.
Example: engine oil cap
XTurn cap :counter-clockwise and remove it.
XAdd the amount of engine oil required.
Observe the specifications in the on-board com-
puter when doing so or fill carefully to the max-
imum mark on the oil dipstick.
The difference betweent he minimum mark and
the maximum mark on the oil dipstick is approx-
imatel y2.1 US qt (2.0 l).
XReplace cap :on the fille rneck and tighten
clockwise.
Ensur ethat the cap locks into place securely.

Breakdown assistance

Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate if the
systemisn ot operating properly. The TPMS
malfunction indicator is combined with the
low tir epressure telltale. When the system
detects amalfunction, the warnin glamp will
flash for approximately aminut eand then
remain continuously illuminated. This
sequence will be repeated every tim ethe vehi-
cle is started as long as the malfunction
exists.
When the malfunction indicator is illuminated,
the syste mmay not be able to detec torsignal
low tir epressure as intended .TPMS malfunc-
tion smay occur for avarietyofr easons,
including the mountin gofincompatible
replacementora lternatetires or wheels on
the vehicle that prevent the TPMS from func-
tioning properly. Always chec kthe TPMS mal-
function telltale afte rreplacing one or more
tires or wheels on your vehicle to ensur ethat
the replacementora lternatetires and wheels
allow the TPMS to continue to function prop-
erly.
It is the driver's responsibility to set the tire
pressure to that recommended for cold tires
which is suitable for the operating situation
(
Ypage 254). Notet hat the correcttirep ressure
for the current operating situation must firstb e
taught-in to the tir epressure monitor .Ifasub-
stantial loss of pressure occurs, the warning
threshold for the warnin gmessageisa ligned to
the taught-in reference values. Restar tthe tire
pressure monitor afte radjusting the pressure of
the cold tires (
Ypage 259). The current pres-
sures are saved as new reference values. As a
result,aw arningmessagew ill appear if the tire
pressure drops significan tly.
The t

ir ep ressure monitor does not warn you of
an incorrectly set tir epressure. Observe the
notes on the recommended tir epressure
(
Ypage 254).
The tir epressure monitor is not able to warn you
of as udden loss of pressure, e.g. if the tir eis
penetrate dbyaforeign object .Inthe eventofa
sudden loss of pressure, bringt he vehicle to a
halt by braking carefully. Avoid abrupt steering
movements.
The tir epressure monitor has ayellow h
warnin glamp on the instrumentc luster for indi-cating
apressure loss or malfunction. The way
that the warnin glamp flashes or lightsupi ndi-
cates whether atirep ressure is too low or
whether the tir epressure monitor is malfunc-
tioning:
Rif the h warnin glamp is lit continuously,
the tir epressure in one or more tires is sig-
nificantly too low. The tir epressure monitor is
not malfunctioning.
Rif the h warnin glamp flashes for around a
minut eand the nremainsl it constantly, the
tir ep ressure monitor is malfunctioning.
In addition to the hwarnin glamp, amessage
appears in the multifunction display. Observe
the information on display messages
(
Ypage 183).
It may tak euptoten minutes for amalfunction
of the tir epressure monitor to be indicated. The
malfunction is indicated firstbyt heh tire
pressure warnin glamp flashingf or approx-
imately one minut eand the nremaining lit. If the
malfunction has been rectified, the htire
pressure warnin glamp goes out afte rdrivingf or
af ew minutes.
The tir epressure values indicated by the on-
board computer may differf rom those meas-
ured at agas st

ation with apressure gauge. The
tir ep ressures shown by the on-board computer
refertot hose measured at sea level. At high
altitudes, the tir epressure values indicated by a
pressure gauge are higher than those shown by
the on-board computer .Inthis case, do not
reduce the tir epressures.
The operation of the tir epressure monitor can
be affected by interference from radio transmit-
tin ge quipment( e.g. radio headphones, two-way
radios) that may be being operated in or near the
vehicle.

Wheels and tires

PSI (pounds per squareinch)
Astandard unit of measure for tire pressure.
Aspect ratio
Relationship between tire height and tire width
in percent.
Tire pressure
This is pressure inside the tire applying an out-
ward force to each square inch of the tire's sur-
face. The tire pressure is specified in pounds per
square inch (psi), in kilopascals (kPa) or in bar.
The tire pressure should only be corrected when
the tires are cold.
Cold tire pressure
The tires are cold:
Rif the vehicle has been parked with the tires
out of direct sunlight for at least three hours
and
Rif the vehicle has not been driven further than
1m ile (1.6 km)
Tread
The part of the tire that comes into contact with
the road.
Bead
The tire bead ensures that the tire sits securely
on the wheel. There are several steel wires in the
bead to prevent the tire from coming loose from
the wheel rim.
Sidewall
The part of the tire between the tread and the
bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kg (5 lbs). These
optional extras, such as high-performance
brakes, level control, aroof rack or ahigh-per-
formanceb attery, are not included in the curb
weight and the weight of the accessories.
TIN (Tire Identification Number)
This is aunique identifier which can be used by
at ire manufacturer to identify tires, for example
for aproduct recall, and thus identify the pur-
chasers. The TIN is made up of the manufactur-
er's identity code, tire size, tire type code and
the manufacturing date.
Load bearing index
The load bearing index (also load index) is acode
that contains the maximum load bearing capa-
city of atire.
Traction
Traction is the result of friction between the tires
and the road surface.
TWR (Tongue Weight Rating)
The TWR specifies the maximum permissible
weight that the ball coupling of the trailer tow
hitch can support.
Treadwear indicators
Narrow bars (tread wear bars) that are distrib-
uted over the tire tread. If the tire tread is level
with the bars, the wear limit of áin (1.6 mm)
has been reached.
Occupant distribution
The distribution of occupants in avehicle at their
designated seating positions.
Total load limit
Nominal load and luggage load plus 68 kg
(150 lbs) multiplied by the number of seats in
the vehicle.

Rotating the wheels
GWARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions. The wheel brakes or suspension components
may also be damaged. There is arisk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.

!On vehicles equipped withatire pressure
monitor, electronic componentsa re located
in the wheel.
Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at aqualified spe-
cialist workshop.
Alwayso bserve the instructionsa nd safety
notes under "Installing awheel" (
Ypage 270).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before aclear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires in the center.
On vehicles that have the same size front and
rear wheels, you can rotate the wheels accord-
ing to the intervals in the tire manufacturer's
warranty book in your vehicle documents. If no
warranty book is available, the tires should be
rotated every 3,000 to 6,000 miles (5,000 to
10,000 km). Depending on tire wear, this may
be required earlier. Do not change the direction
of wheel rotation.
Cleant he contact surfaces of the wheel and the
brake disc thoroughly every time awheel is rota-
ted. Check the tire pressure and reactivate the
tire pressure monitor if necessary (
Ypage 259).
Direction of rotation
Tires with aspecified direction of rotation have
additional benefits, e.g. if there is arisk of hydro-
planing. 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 the spare wheel against the
direction of rotation. Adhere to the time restric-
tion on use as well as the speed limitation speci-
fied on the spare wheel.
Storing wheels
Store tires that are not being used in acool, dry
and preferably dark place. Protect the tires from
oil, grease, gasoline and diesel.
