2015 MERCEDES-BENZ GLK-CLASS SUV snow chains

Check the tires regularly for signs of damage
and replace any damaged tires immediately.
M+S tires
GWARNING
M+S tires with a tire tread depth of less than ã in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There is
a risk of an accident.
M+S tires with a tread depth of less than ã in
(4 mm) must be replaced immediately.
At temperatures below 45 ‡ (+7 †), use win-
ter tires or all-season tires. Both types of tire are identified by the M+S marking.
Only winter tires bearing the i snowflake
symbol in addition to the M+S marking pro-
vide the best possible grip in wintry road con-
ditions. Only these tires will allow driving
safety systems such as ABS and ESP ®
to
function optimally in winter. These tires have
been developed specifically for driving in
snow.
Use M+S tires of the same make and tread on all wheels to maintain safe handling charac-
teristics.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
When you have mounted M+S tires:
X Check the tire pressures ( Y page 339).
X Restart the tire pressure monitor
(Y page 339).
For more information on driving with the
emergency spare wheel, see ( Y page 366).
Snow chains
GWARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is a risk of an accident.
To avoid hazardous situations:
R never install snow chains to the front
wheels
R always install snow chains in pairs to the
rear wheels.
! On some tire sizes there is not enough
space for snow chains. To avoid damage to
the vehicle or tires, observe the "Wheel and tire combinations" section under "Tires and
wheels".
! Vehicles with steel wheels: if you
mount snow chains on steel wheels, you
may damage the hub caps. Remove the hub caps from the relevant wheels before
mounting the snow chains.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that
have been specially approved for your vehicle
by Mercedes-Benz, or are of a corresponding standard of quality. For more information,
please contact a qualified specialist work-
shop.
If you intend to mount snow chains, please
bear the following points in mind:
R Snow chains may not be mounted on all
wheel/tire combinations. Permissible
wheel-tire combinations ( Y page 360).
R Only use snow chains when driving on
roads completely covered by snow.
Remove the snow chains as soon as possi-
ble when you come to a road that is not
snow-covered.
R Local regulations may restrict the use of
snow chains. Observe the appropriate reg-
ulations if you wish to mount snow chains.
R Do not exceed the maximum permissible
speed of 30 mph (50 km/h).
iYou may wish to deactivate ESP ®
( Y page 71) when pulling away with snow
chains installed. You can thereby allow the wheels to spin in a controlled manner, ach-

Emergency spare wheel
Important safety notes
GWARNING
The wheel or tire size as well as the tire type ofthe 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
You should regularly check the pressure of
the emergency spare wheel, particularly prior
to long trips, and correct the pressure as nec-
essary ( Y page 336). The applicable value can
be found on the wheel or under "Technical
data" ( Y page 360).
iWhen you are driving with the emergency
spare wheel mounted, the tire pressure
monitor cannot function reliably. Only
restart the tire pressure monitor when the
defective wheel has been replaced with a
new wheel. If an emergency spare wheel is mounted,
the system may continue to show the tire
pressure of the wheel that has been
removed for a few minutes. The value dis-
played 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 emer-
gency 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 spare wheel
The collapsible spare wheel can be found in
the stowage well under the cargo compart-
ment floor.
X Lift the cargo compartment floor upwards
(Y page 281).
X
Remove stowage compartment :.
X Turn retaining screw ; counter-clockwise
and remove it.
X Remove collapsible spare wheel =.
X Take the wheel bolts for the collapsible
spare wheel from the vehicle tool kit.
For further information on changing a wheel
and mounting the spare wheel, see
( Y page 314).
