396 OperationTires and wheelsMaximum load rating
The maximum load in kilograms and
pounds that can be carried by the tire.
Maximum loaded vehicle weight
The sum of curb weight, accessory weight,
total load limit, and production options
weight.
Maximum tire inflation pressure
This number is the greatest amount of air
pressure that should ever be put in the tire
under normal driving conditions.
Normal occupant weight
The number of occupants the vehicle is
designed to seat, multiplied by
68 kilograms (150 lbs).
Occupant distribution
The distribution of occupants in a vehicle
at their designated seating positions.Production options weight
The combined weight of those installed
regular production options weighing over
5 lbs (2.3 kilograms) in excess of those
standard items which they replace, not
previously considered in curb weight or
accessory weight, including heavy duty
brakes, ride levelers, roof rack, heavy duty
battery, and special trim.
PSI (P
ounds per s
quare i
nch)
A standard unit of measure for air pressure
-> bar, kilopascal (kPa).
Recommended tire inflation pressure
Recommended tire inflation pressure
listed on placard located on driver’s door
B-pillar for normal driving conditions.
Provides best handling, tread life and
riding comfort.Rim
A metal support for a tire or a tire and tube
assembly upon which the tire beads are
seated.
Sidewall
The portion of a tire between the tread and
the bead.
TIN (T
ire I
dentification N
umber)
Unique identifier which facilitates efforts
by tire manufacturers to notify purchasers
in recall situations or other safety matters
concerning tires and gives purchases the
means to easily identify such tires. The TIN
is comprised of “Manufacturer’s identifica-
tion mark”, “Tire size”, “Tire type code”
and “Date of manufacture”.
Tire load rating
Numerical code associated with the
maximum load a tire can support.

Preparing the vehicle
Prepare the vehicle as described
(page 497).Vehicles with Minispare wheel:
Take the wheel wrench, the collapsible
wheel chock, and the vehicle jack out
of the cargo compartment
(page 469).
Take the Minispare wheel out of the

Vehicles with collapsible tire
(ML 63 AMG only):
Take the collapsible tire, wheel wrench,
wheel bolts, jack, and electric air pump
out of the cargo compartment
(page 474).Lifting the vehicle
i
Vehicles with collapsible tire:
You can use the power outlet in the cargo com-
partment or in the front of the rear seats to oper-
ate the electric air pump even when the ignition
is switched off, e.g. in order to inflate the col-
lapsible emergency spare tire.
An emergency shut-off feature ensures that the
vehicle’s electrical voltage does not fall below a
minimum level. If the voltage drops to this mini-
mum level, the power outlets are automatically
switched off. This ensures that enough power re-
mains to start the engine.

Vehicles with factory-mounted
running-boards*:
Your vehicle is equipped with a scissors-type
jack (located under the cargo compartment
floor) designed for use with factory-mounted
running boards. Only use this jack when jacking
up vehicles with factory-mounted running boards
as otherwise the vehicle’s underbody can be
damaged. See separate instructions for
scissors-type jack.
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use,
especially on hills. Always try to use the jack
on level surface. Make sure that the jack
arm is fully seated in the jack take-up brack-
et. Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.

499 Practical hints
Flat tire
Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
or other sizable objects.
One collapsible wheel chock is includ-
ed with the vehicle tool kit
(page 469). For information on set-
ting up the collapsible wheel chock,
see (page 472).
When changing wheel on a level surface:
Place one wheel chock in front of and
another sizeable object behind the
wheel that is diagonally opposite to the
wheel being changed.
Always try lifting the vehicle using the jack
on a level surface. However, should
circumstances require you to do so on a
hill, place the wheel chock and another
sizeable object as follows:
Place the wheel chock and another
sizable object on the downhill side
blocking both wheels of the axle not
being worked on.1Wheel wrench
On wheel to be changed, loosen but do
not yet remove the wheel bolts
(approximately one full turn with wheel
wrench1).
The jack take-up brackets are located di-
rectly behind the front wheel housings and
in front of the rear wheel housings.2Take-up bracket

Do not position the jack on the body of the
vehicle, as this may cause damage to the
vehicle.
