Storage pockets
GWARNING
Storage bags are intended for storing light-
weight items only.
Heavy objects, objects with sharp edges or
fragile objects may not be transported in the
storage bag. In an accident, during hard
braking, or sudden maneuvers,they could be
thrown around inside the vehicle and cause
injurytovehicle occupants.
Storage bags cannot protecttransported
goods in the event of an accident.
The stowage pockets are on the back of the
driver's and front-passenger'sseats.
Stowage nets
Stowage netsare located in the front-
passenger footwell and on the right-hand side
of the trunk.
Observe the loading guidelines (Ypage 278)
and the safety notes regarding stowage
spaces (Ypage 278).

feature
Important safetynotes
GWARNING
If the rear bench seat/rear seat and seat
backrest are not engaged they could fold
forwards, e.g. when brakingsuddenly or in the
event of an accident.
RThe vehicle occupantwould thereby be
pushed into the seat belt by the rear bench
seat/rear seat or by the seat backrest.The
seat belt can no longer offer the intended
level of protection and could even cause
injuries.
RObjectsorloads in the trunk cannot be
restrained by the seat backrest.
There is an increased risk of injury.
Before every trip, make sure that the seat
backrests and the rear bench seat/rear seat
are engaged.
Observe the loading guidelines (Ypage 278).
The left-hand and right-hand rear seat
backrests can be folded down separately to
increase the trunk capacity.

XVehicles with AIRMATIC: make sure that
"normal" level is selected (Ypage 189).
XSwitch off the engine.
XVehicles without KEYLESS-GO:remove
the SmartKey from the ignition lock.
XVehicles with KEYLESS-GO:open the
driver's door.

(Ypage 147).
XAll occupants must get out of the vehicle.
Make sure that they are not endangered as
they do so.
XMake sure that no one is near the danger
area whileawheel is being changed.
Anyone who is not directly assisting in the
wheel change should, for example, stand
behind the barrier.
XGet out of the vehicle. Pay attention to
traffic conditionswhen doing so.
XClose the driver's door.
MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there isatotal loss of
pressure in one or more tires. The affected
tire must not show any clearly visible damage.
You can recognizeMOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
next to the tire size designation, the load-
bearing capacity and the speed index
(Ypage 351).
MOExtended tires may only be used in
conjunction with an active tire pressure loss
warning system or with an active tire pressure
monitor.
If the pressureloss warning message
appearsinthe multifunction display:
RObserve the instructions in the display
messages (Ypage 258).
RCheck the tire for damage.
RIf driving on, observe the following notes.
The maximum driving distance is
approximately 50 miles (80 km) when the
vehicle is partially laden and approximately
18 miles (30 km) when the vehicle is fully
laden.

Determining thecorrect loadlimit
Step-by-step instructions
The followingsteps have been developedas
required of all manufacturers under Title 49,
Code of U.S.Federal Regulations, Part 575
pursuant to the "National Traffic and Motor
Vehicle SafetyActof 1966".
XStep 1:Locatethe statement "The
combined weight of occupants and cargo
should never exceed XXX kg or XXX lbs." on
your vehicle’s Tire and Loading Information
placard.
XStep 2:Determine the combined weight of
the driver and passengers that will be riding
in your vehicle.
XStep 3:Subtract the combined weight of
the driver and passengers from XXX
kilograms or XXX lbs.
XStep 4:The resultingfigure equals the
available amount of cargo and luggage load
capacity. For example, if the "XXX" amount
equals 1400lbs and therewill be five
150 lbs passengersinyour vehicle, the
amount of available cargo and luggage load
capacityis650 lbs (1400-750 (5x150) =
650 lbs).
XStep 5:Determine the combined weight of
luggage and cargo being loaded on the
vehicle. Thatweight may not safely exceed
the available cargo and luggage load
capacity calculated in step 4.

GWARNING
Exceeding the stated tire load-bearing

General:depending on the manufacturer's
standards, the size imprinted in the tire wall
may not contain any letters or may contain
one letter that precedes the size description.
If there is no letter preceding the size
description (as shown above): these are
passenger vehicle tires according to

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.

GAWR (Gross Axle Weight Rating)
The GAWR is the maximum gross axle weight
rating. The actual load on an axle must never
exceed the gross axle weight rating. The
gross axle weight rating can be found on the
vehicle identification plate on the B-pillar on
the driver's side.
Speed rating
The speed rating is part of the tire
identification. It specifies the speed range for
which the tire is approved.

Curbweight
The weight ofavehicle with standard
equipment includingthemaximum capacity
of fuel, oil and coolant.Italso includes the air-

The maximum tireload is the maximum
permissible weight in kilograms or lbs for
whichatireisapproved.
Maximumpermissible tirepressure
Maximum permissible tirepressure for one
tire.
Maximumload on one tire
Maximum load on one tire. This is calculated
by dividingthe maximum axle load of one axle
by two.
PSI (pounds per squareinch)
Astandardunitofmeasure for tire pressure.
Aspect ratio
Relationship between tire height and tire
width in percent.
Tirepressure
This is pressure inside the tire applying an
outward forcetoeach 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.
Cold tirepressure
The tires are cold:
Rif the vehicle has been parked without
direct sunlight on the tires for at least three
hours and
Rif the vehicle has been driven for less than
1mile (1.6 km).
Tread
The part of the tire that comes intocontact
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 preventthe tire from
comingloose 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 kilograms (5 lbs).
These optional extras, such as high-
performance brakes, level control,aroof rack
orahigh-performancebattery, are not
included in the curb weight and the weight of
the accessories.
TIN (Tire Identification Number)
This isaunique identifier which can be used
byatire manufacturer to identify tires, for
example foraproduct 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 ofatire.
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.
