2013 MERCEDES-BENZ GLK-Class wheel

Observe the notes on recommended tire
pressures under various operating
conditions (Y
page 331).
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.
i Notes on the vehicle equipment –always
equip the vehicle with:
R tires of the same size on a given axle
(left/right)
R the same type of tires at a given time
(summer tires, winter tires, MOExtended
tires)
i On 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 equipmen tor
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.
The tires and wheel rims, as well as further
information, can be obtained at a qualified
specialist workshop.
i Overview of abbreviations used in the
following tire tables:
R BA: both axles
R FA: front axle
R RA: rear axle In the following table, the wheel/tire
combinations are assigned to the vehicle
models through variants, e.g. V1, V2 etc.: V1

Emergency spare wheel
Important safety notes
G
WARNING
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 you rdriving style accordingly and
drive carefully.
R never mount more than one spare wheel or
emergency spare wheel that differs in size.
18 USA: not for GLK 250 BlueTEC.
19 Use of snow chains is not permitted .Observe the notes in the "Snow chains" section.
20 MOExtended tires (tires featuring run-flat characteristics) only in combination with an activated tire pressure
loss warning system. Emergency spare wheel
359Wheels and tires
Z

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
emergency spare wheels. General notes
You should regularly check the pressure of
the emergency spare wheel, particularly prior
to long trips, and correc tthe pressure as
necessary (Y page 331). The applicable value
is found on the wheel or under "Technical
data" (Y page 357).
i When 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 pressurem onitor:
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.
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. Collapsible spare wheel
Removing the collapsible emergency
spare wheel The collapsible spare wheel can be found in
the stowage well under the cargo
compartment floor.
X

compressor for longer than eight minutes
at a time without a break. It may otherwise
overheat.
The tire inflation compressor can be

pressure.
The specified tire pressure is printed on the
yellow label of the emergency spare wheel.
X When the specified tire pressure has been
reached, press on/offs witch001Eon the
electric air pump to 0.
The tire inflatio ncompressor is switched
off. X
Turn the SmartKey to position 0in the
ignition lock.
X If the tire pressure is higher than the
specified pressure, press pressure release
button 0003until the correc ttire pressure has
been reached.
X Unscrew union nut 0002on the air hose from
the valve.
X Screw the cap onto the valve of the
collapsible spare wheel again.

section of the blower housing.
X Stow the tire inflation compressor in the
vehicle.
Stowing aused collapsible spare wheel Take the following steps to stow a used
collapsible spare wheel. Otherwise, the
collapsible spare wheel will not fit in the spare
wheel well. Mercedes-Benz recommends that
you have this work carried out at a qualified
specialist workshop.
!
Only place the collapsible spare wheel in
the vehicle when it is dry. Otherwise,
moisture may get into the vehicle.
X Remove the valve extractor from the
vehicle tool kit.
X Unscrew the valve cap from the valve.
X Unscrew the valve insert from the valve and
release the air.
i Fully deflating the tires can take a few
minutes.
X Screw the valve insert back into the valve.
X Screw the valve cap back on.
