Mercedes-Benz GL-Class 2015 - Manual (Page 411)

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 sys-
tems such as ABS and ESP ® to function opti-
mally in winter. These tires have been devel-
oped 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.
Once the winter tires are mounted:
X
Check the tire pressures (
Y
page 413).
X
Restart the tire pressure monitor
(
Y
page 414).
X Vehicles for Canada: restart the tire pres-
sure loss warning system (
Y
page 414).

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 instal-
led. The vehicle may otherwise be dam-
aged.
! Vehicles with Adaptive Damping Sys-
tem (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 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.
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 possi-
ble 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 reg-
ulations 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 434).
i You may wish to deactivate ESP ® when
pulling away with snow chains installed
(
Y
page 74). You can thereby allow the
wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action).

emergency spare wheel, see (
