tires MERCEDES-BENZ GL 2014 Workshop Manual

Rbefore raising the vehicle, secure it from
rolling away by applying the parking brake
and inserting wheel chocks. Do not
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, flat, 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 that the 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.
Rdo not lie under the vehicle.
Rdo not 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.
XUsing lug wrenchC, 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
front wheel housings and just in front of the
rear wheel housings (arrows).
XTake the ratchet wrench out of the vehicle
tool kit and place it on the hexagon nut of
the jack so that the lettersAUFare visible.

These tires have been specially adapted for
use with the control systems, such as ABS
or ESP®, and are marked as follows:
RMO = Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended
(tires featuring run-flat characteristics)
RMO1 = Mercedes-Benz Original (only
certain AMG tires)
Mercedes-Benz Original Extended tires
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tires, wheels or accessories
tested and approved by Mercedes-Benz.
Certain characteristics, e.g. handling,
vehicle noise emissions or fuel
consumption, may otherwise be adversely
affected. In addition, when driving with a
load, tire dimension variations could cause
the tires to come into contact with the
bodywork and axle components. This could
result in damage to the tires or the vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tires,
wheels or accessories other than those
tested and approved.
Information on tires, wheels and approved
combinations can be obtained from any
qualified specialist workshop.
!Retreaded tires are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be
detected on retreaded tires. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tires are mounted. Do
not mount used tires if you have no
information about their previous usage.
Overview of abbreviations used in the
following tire tables:
RBA: both axles
RFA: front axle
RRA: rear axle
The recommended pressures for various
operating conditions can be found:
Ron the Tire and Loading Information placard
with the recommended tire pressures on
the B-pillar on the driver's side
Rin the tire pressure table on the inside of
the fuel filler flap
Observe the notes on recommended tire
pressures under various operating conditions
(Ypage 408).
Check tire pressures regularly, and only when
the tires are cold. Comply with the
maintenance recommendations of the tire
manufacturer in the vehicle document wallet.
Notes on the vehicle equipment – always
equip the vehicle with:
Rtires of the same size on a given axle (left/
right)
Rthe same type of tires at a given time
(summer tires, winter tires, MOExtended
tires)
Vehicles with MOExtended tires are not
equipped with a TIREFIT kit at the factory. It
is therefore recommended that you
additionally equip your vehicle with a TIREFIT
kit if you mount tires that do not feature run-
flat properties, e.g. winter tires. A TIREFIT kit
may be obtained from a qualified specialist
workshop.
iNot all wheel and tire combinations are
available at the factory for all countries.
iOn the following pages, you can find
information on approved wheel rims and
tire sizes for equipping your vehicle with
winter tires. Winter tires are not available
at the factory as standard equipment or
optional extras.
If you would like to equip your vehicle with
approved winter tires, you may also, in
certain circumstances, require rims of the
appropriate size. The size of the approved
winter tires may deviate from that of the
standard tires. This is dependent on the
model and the equipment installed at the
factory.

Wheels and ti res

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:
Radapt your driving style accordingly and
drive carefully.
Rnever mount more than one spare wheel or
emergency spare wheel that differs in size.
Ronly use a spare wheel or emergency spare
wheel of a different size briefly.
Rdo not switch ESP®off.
Rhave 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.
!AMG vehicles with "Minispare"
emergency spare wheel:use the
"Minispare" emergency spare wheelonly
on the rear axle. If you mount the
"Minispare" emergency spare wheel on the
front axle, this could result in damage to the
brake system.
If a tire on the front axle is defective, an
intact wheel from the rear axle must first
be replaced with the "Minispare"
emergency spare wheel. The defective
wheel on the front axle can then be
replaced with the intact wheel from the rear
axle.
Make sure to note the placard on the
"Minispare" emergency spare wheel.
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
emergency spare wheels.
General notes
Mounting the emergency spare wheel is
described under "Mounting a wheel"
(Ypage 428).
You should regularly check the pressure of
the emergency spare wheel, particularly prior
to long trips, and correct the pressure as
necessary (Ypage 408). The value on the
wheel or as given in the "Wheels and tires"
section is valid (Ypage 441).
An emergency spare wheel may also be
mounted against the direction of rotation.
Observe the time restriction on use as well as
the speed limitation specified on the
emergency spare wheel.
Replace the tires after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
iWhen you are driving with the collapsible
spare wheel mounted, the tire pressure
loss warning system or the tire pressure
monitor cannot function reliably. Only
restart the tire pressure loss warning
system/the tire pressure monitor when the
damaged wheel has been replaced with a
new wheel.
Vehicles with tire pressure monitor:
after mounting an emergency spare wheel,
the system may still display the tire
pressure of the removed wheel for a few
minutes. The value displayed for the
mounted emergency spare wheel is not the
same as the current tire pressure of the
emergency spare wheel.
