Mercedes-Benz GL-Class 2013 Owners Manual - Manual (Page 405)

Only winter tires bearing the i snowflake
symbol in addition to the M+S marking
provide the best possible grip in wintry road
conditions.
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
characteristics.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
Once the winter tires are mounted:
X
Check the tire pressures (
Y
page 407).
X
Restart the tire pressure monitor
(
Y
page 408).
X Vehicles for Canada: restart the tire
pressure loss warning system
(
Y
page 408).
For more information on driving with the
emergency spare wheel, see (

Snow chains
G WARNING
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.
! You must drive at raised vehicle level
(height 1) if snow chains have been
installed. The vehicle may otherwise be
damaged.
! Vehicles with Adaptive Damping
System (ADS): do not use the sports mode
if you have installed snow chains. The
vehicle may otherwise be damaged.
! 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".
For safety reasons, Mercedes-Benz
recommends 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.
If you intend to mount snow chains, please
bear the following points in mind:
R Only use snow chains when driving on
roads completely covered by snow.
Remove the snow chains as soon as
possible when you come to a road that is
not snow-covered.
R Do not exceed the maximum permissible
speed of 30 mph (50 km/h).
R Local regulations may restrict the use of
snow chains. Observe the appropriate
regulations if you wish to mount snow
chains.
R Snow chains may not be mounted on all
wheel/tire combinations. Permissible
wheel-tire combinations (
Y
page 428).
i You may wish to deactivate ESP ® when
pulling away with snow chains installed
(
Y
page 72). This way you can allow the
wheels to spin in a controlled manner,
achieving an increased driving force
(cutting action).

emergency spare wheel, see (
