Parking tips:
ROn narrow roads, drive as close to the
parking space as possible.
RParking spaces that are littered or
overgrown might be identified or measured
incorrectly.
RParking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
RSnowfall or heavy rain may lead to a parking
space being measured inaccurately.
RPay attention to the PARKTRONIC
(Ypage 176) warning messages during the
parking procedure.
RYou can intervene in the steering procedure
to correct it at any time. Active Parking
Assist will then be canceled.
RWhen transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
RNever use Active Parking Assist when snow
chains are installed.
RMake sure that the tire pressures are
always correct. This hasadirectinfluence
on the parking characteristics of the
vehicle.
Use Active Parking Assist for parking spaces:
Rthatare parallel or at right-angles to the
direction of travel
Rthat are on straight roads, not bends
Rthat are on the same level as the road, e.g.
not on the pavement
Detecting parking spaces
Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles.
GWARNING
If there are objects above the detection range,
Active Parking Assist may turn prematurely.
You may cause a collision as a result. There is
a risk of an accident.
If there are objects above the detection range,
stop and deactivate Active Parking Assist.
For further information on the detection
range (Ypage 175).
Active Parking Assist does not support you
with parking spaces at right-angles to the
direction of travel if:
Rtwo parking spaces are located directly
next to one another
Rthe parking space is directly next to a low
obstacle such as a low curb
Ryou park forwards
Active Parking Assist does not support you
with parking spaces that are parallel or at
right-angles to the direction of travel if:
Rthe parking space is onacurb
Rthe parking space is apparently blocked,
for example by foliage or grass paving
blocks
Rthe range of movement is too small
Rthe parking space is bordered by an
obstacle which is notclearly defined such
as a tree or a trailer

Engine oil
General notes
Depending on the driving style, the vehicle
consumes up to 0.9 US qt (0.8 liters) of oil
overadistanceof600 miles(1,000 km). The
oil consumption may be higher than this when
the vehicle is new or if you frequently drive at
high engine speeds.
Depending on the engine, the oil dipstickmay
be in a different location.
When checking the oil level:
Rpark the vehicle on a level surface.
Rthe engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
Rif the engine is not at normal operating
temperature, e.g.ifthe engine was only
started briefly: wait about 30 minutes
before carrying out the measurement.

iTire data is vehicle-specific and may
deviate from the data in the example.
General:depending on the manufacturer's
standards, the size imprinted in the tire wall
may not contain any letters or may contain
one letterthat precedes the size description.
If there is no letter preceding the size
description (as shown above): these are
passenger vehicle tires according to
European manufacturing standards.
If "P" precedes the size description: these are
passenger vehicle tires according to U.S.
manufacturing standards.
If "LT" precedes the size description: these
are light truck tires according to U.S.
manufacturing standards.
If "T" precedes the size description: these are
compact emergency spare wheels at high tire
pressure, to be used only temporarily in an
emergency.
Tire width:tire widthshows the nominal
tire width in millimeters.
Nominal aspect ratio:aspect ratiois the
size ratio between the tire height and the tire
width and is shown in percent.The aspect
ratio is calculated by dividing the tire width by
the tire height.
Tire code:tire code"specifies the tire type.
"R" represents radial tires; "D" represents
diagonal tires; "B" represents diagonal radial
tires.
Optionally, tires with a maximum speed of
over 149mph (240km/h) may have "ZR" in
the size description, depending on the
manufacturer (e.g. 245/40 ZR 18).
Rim diameter:rim diameter!is the
diameter of the bead seat, not the diameter
of the rim flange. The rim diameter is
specified in inches (in).
Load bearing index:load bearing index
is a numerical code which specifies the
maximum load-bearing capacity of a tire.
Do not overload the tires by exceeding the
specified load limit. The maximum
permissible load can be found on the
vehicle's Tire and Loading Information
placard on the B-pillar on the driver's side
(Ypage 323).
Example:
Aload-bearing index of 91 indicates a
maximum load of 1,356lb (615kg) that can be
carried by the tires. For further information on
the maximum tire load in kilograms and
pounds, see (Ypage 327).
For further information on the load-bearing
index, see Load index (Ypage 332).
Speed rating:speed rating specifies the
approved maximum speed of the tire.
GWARNING
Exceeding the stated tire load-bearing
capacity and the approved maximum speed
could lead to tire damage or the tire bursting.
There is a risk of accident.
Therefore, only use tire types and sizes
approved for your vehicle model. Observe the
tire load rating and speed rating required for
your vehicle.
Regardless of the speed rating, always
observe the speed limits. Drive carefully and

Aspect ratio
Relationship between tire height and tire
width in percent.
Tire pressure
This is pressure inside the tire applying an
outward force to each square inch of the tire's
surface. The tire pressure is specified in
pounds per square inch (psi), in kilopascal
(kPa) or in bar. The tire pressure should only
be corrected when the tires are cold.
Tire pressure of cold tires
The tires are cold:
Rif the vehicle has been parked without
direct sunlightonthe tires for at least three
hours and
Rif the vehicle has not been driven further
than 1 mile (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
part and more than 2.3 kg (5 lbs). These
optional extras, such as high-performance
brakes, level control, a roof rack or a high-
performance battery, are not included in the
curb weight and the weight of the
accessories.
TIN (Tire Identification Number)
This is a unique identifier which can be used
by a tire manufacturer to identify tires, for
example for a product recall, and thus identify
the purchasers. The TIN is made up of the
manufacturer's identity code, tire size, tire
type code and the manufacturing date.
Load bearing index
The load bearing index (also load index) is a
code that contains the maximum load bearing
capacity of a tire.
Traction
Traction is the result of friction between the
tires and the road surface.
Treadwear indicators
Narrow bars (tread wear bars) that are
distributed over the tire tread. If the tire tread
is level with the bars, the wear limit ofin
(1.6 mm) has been reached.
Occupant distribution
The distribution of occupants in a vehicle at
their designated seating positions.
Total load limit
Nominal load and luggage load plus
68 kilograms (150 lb) multiplied by the
number of seats in the vehicle.

Observe the following when raising the
vehicle:
Rto raise the vehicle, only use the vehicle-
specific jack that has been tested and
approved by Mercedes-Benz.Ifused
incorrectly, the jack could tip over with the
vehicle raised.
Rthe jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed. It is not suited for
performing maintenance work under the
vehicle.
Ravoid changing the wheel on uphill and
downhill slopes.
Rbefore raising the vehicle, secure it from
rolling away by applying the parking brake
and inserting wheel chocks. Never
disengage the parking brake while the
vehicle is raised.
Rthe jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a
large, load-bearing underlay must be used.
On a slippery surface, a non-slip underlay
must be used, e.g. rubber mats.
Rdo not use wooden blocks or similar
objects as a jack underlay.Otherwise, the
jack will not be able to achieve its load-
bearing capacity due to the restricted
height.
Rmake sure thatthe distance between the
underside of the tires and the ground does
not exceed 1.2 in (3 cm).
Rnever place your hands and feet under the
raised vehicle.
Rnever lie under the raised vehicle.
Rnever start the engine when the vehicle is
raised.
Rnever open or close a door or the tailgate
when the vehicle is raised.
Rmake sure that no persons are present in
the vehicle when the vehicle is raised.
!The jack is designed exclusively for
jacking up the vehicle at the jacking points.
Otherwise, your vehicle could be damaged.
Steel wheel with wheel trim
XVehicles with steel wheels:carefully
reach into two of the wheel trim openings
and remove the wheel trim.
XUsing lug wrench, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts
completely.
The jacking points are located just behind the
wheel housings of the front wheels and just
in front of the wheel housings of the rear
wheels (arrows).
