Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
!The tailgate swings upwards and to the
rear when opened. Therefore, make sure
that there is sufficient clearance above and behind the tailgate.
iThe opening dimensions of the tailgate
can be found in the "Vehicle data" section ( Y page 341).
You should preferably place luggage or loads in the cargo compartment. Observe the load-
ing guidelines ( Ypage 248).
Do not leave the SmartKey in the cargo com- partment. You could otherwise lock yourself
out.
The tailgate can be:
R opened and closed manually from outside
R released with the emergency release from
the inside
Opening/closing from outside
Opening
X Press the %button on the SmartKey.
X Pull handle :.
X Raise the tailgate.
Closing

X Allow the tailgate to drop into the lock.
X If necessary, lock the vehicle with the &
button on the SmartKey or with KEYLESS-
GO.

General notes
!The tailgate swings upwards and to the
rear when opened. Therefore, make sure
that there is sufficient clearance above and behind the tailgate.
iThe opening dimensions of the tailgate
can be found in the "Vehicle data" section ( Y page 341).
If the tailgate can no longer be unlocked:
R using the SmartKey, or
R using the remote operating switch in the
door control panel:
Use the emergency release on the inside of
the tailgate.
You can reach the emergency release via the cargo compartment.
80Cargo compartment
Opening and closing
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel:R monthly, at least
R if the load changes
R before beginning a long journey
R under different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
iThe specifications on the sample Tire and
Loading Information placard and tire pres-
sure tables are examples. Tire pressure
specifications are vehicle-specific and may
deviate from the data shown here. The tire pressure specifications that are valid for
your vehicle can be found on the Tire and
Loading Information placard and tire pres-
sure table on the vehicle.
General notes
The recommended tire pressures for the tires
mounted at the factory can be found on the
labels described here.
Operation with the emergency spare
wheel (Y page 329).
Further information on tire pressures can be
obtained at a qualified specialist workshop.
Tire and Loading Information placard
:Recommended tire pressures
The Tire and Loading Information placard is
on the B-pillar on the driver's side( Y page 310). The Tire and Loading Information placard con-
tains the recommended tire pressures for
cold tires. The recommended tire pressures
are valid for the maximum permissible load
and up to the maximum permissible vehicle
speed.
Tire pressure table
The tire pressure table is on the inside of the
fuel filler flap.
Example: tire pressure table for all tires permitted
for this vehicle by the factory
The tire pressure table contains the recom-
mended pressures for cold tires for various
operating conditions, i.e. differing load and
speed conditions.
Example: tire pressure table with tire dimensions
If a tire size precedes a tire pressure, the tire pressure information following is only valid
for that tire size. The load conditions "partially
laden" and "fully laden" are defined in the
table for different numbers of occupants and
amounts of luggage. The actual number of
seats may differ.
306Tire pressure
Wheels and tires
Occupant distribution
The distribution of occupants in a vehicle at
their designated seating positions.
Total load limit
Nominal load and luggage load plus 68 kg
(150 lbs) multiplied by the number of seats inthe vehicle.
Changing a wheel
Flat tire
The "Breakdown assistance" section ( Y page 284) contains information and notes
on how to deal with a flat tire. Information on driving with MOExtended tires in the event of
a flat tire can be found under "MOExtended
tires (tires with run-flat characteristics"( Y page 285).
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 a risk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
Observe the instructions and safety notes in
the "Changing a wheel" section ( Ypage 322).
The wear patterns on the front and rear tires
differ, depending on the operating conditions. Rotate the wheels before a clear wear patternhas formed on the tires. Front tires typically
wear more on the shoulders and the rear tires
in the center.
If your vehicle's tire configuration allows, you can rotate the wheels according to the inter-
vals 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), or earlier if tire wear requires.
Ensure the direction of rotation is maintained.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is rotated. Check the tire pressure and, if nec-
essary, restart the tire pressure loss warning system.
Direction of rotation
Tires with a specified direction of rotation
have additional benefits, e.g. if there is a risk of hydroplaning. These advantages can only
be gained if the tires are installed correspond-
ing to the direction of rotation.
An arrow on the sidewall of the tire indicates its correct direction of rotation.
Storing wheels
Store wheels that are not being used in a cool,dry and preferably dark place. Protect the
tires from oil, grease, gasoline and diesel.
Mounting a wheel
Preparing the vehicle
X Stop the vehicle on solid, non-slippery and
level ground.
X Apply the electric parking brake manually.
X Bring the front wheels into the straight-
ahead position.
X Shift the transmission to position P.
X Switch off the engine.
X Vehicles without KEYLESS-GO: remove
the SmartKey from the ignition lock.
X Vehicles with KEYLESS-GO start-func-
tion or KEYLESS-GO: open the driver's
door.
The on-board electronics now have status0 . This is the same as the SmartKey having
been removed.

Emergency spare wheel
Important safety notes
GWARNING
The wheel or tire size as well as the tire type of
the spare wheel or emergency spare wheel
and the wheel to be replaced may differ.
Mounting an emergency spare wheel may
severely impair the driving characteristics.
There is a risk of an accident.
To avoid hazardous situations:
R adapt your driving style accordingly and
drive carefully.
R never mount more than one spare wheel or
emergency spare wheel that differs in size.
R only use a spare wheel or emergency spare
wheel of a different size briefly.
R do not switch ESP ®
off.
R have a spare wheel or emergency spare
wheel of a different size replaced at the
nearest qualified specialist workshop.
Observe that the wheel and tire dimensions
as well as the tire type must be correct.
When using an emergency spare wheel or
spare wheel of a different size, you must not
exceed the maximum speed of 50 mph
(80 km/ h).
Snow chains must not be mounted on emer-
gency spare wheels.
General notes
Apart from some country-specific variants,
the vehicles are not equipped with an emer-
gency spare wheel. Emergency spare wheels
are specific to the vehicle. For more informa- tion on which emergency spare wheels are
approved for your vehicle, consult a qualified specialist workshop.
2 Also available as MOExtended tires.
3 Use of snow chains not permitted. Observe the notes in the "Snow chains" section.
