The road's course is suitable, e.g. no steep
uphill or downhill inclines or tight bends.
R There is no trailer hitched up tothe trailer
hitch, and no bicycle rack /tted.
R You do not depress the accelerator or brake
pedal (e xcept for light brake applications).
% Glide mode can also be activated if you ha ve
selected the "Eco" setting forth e drive in the
drive prog ram =.
Glide mode is deactivated again if one of the con-
ditions is no longer met.
Glide mode can also be pr evented bythefo llowing

4MATIC ensu resth at all four wheels are driven.
To get her with ESP ®
and 4ETS, 4MATIC impr oves
th e traction of your vehicle whene ver a driven
wheel spins due toinsu1cient traction.
If yo ufa ilto adapt your driving style, 4MATIC can
neither reduce therisk of an accident nor override
th e la wsof ph ysics. 4MATIC cannot take account
of road, weather and tra1c conditions. 4MATIC is
only an aid. You are responsible especially for
maintaining a safe distance from theve hicle in
front, forve hicle speed, for braking in good time
and for st aying in lane.
% In wintry road conditions, the maximum e.ect
of 4MATIC can be achie ved only if you use
winter tyres (M+S tyres), with snow chains if
necessar y. R

If
th eve hicle deviates from the direction desired
by the driver, ESP ®
can stabilise theve hicle by
inter vening in thefo llowing ways:
R One or more wheels are braked.
R The engine output is adap ted according tothe
situation.
When ESP ®
is deacti vated, theå warning
lamp lights up continuousl y:
R Driving stability will no longer be impro ved.
R The drive wheels could spin.
R ETS/4ETS traction control is still active.
% When ESP ®
is deactivated, you are still assis-
te dby ESP ®
when braking.
When the÷ warning lamp 0ashes, one or se v-
eral wheels has reached its grip limit:
R Adapt your driving style tosuit the cur rent
ro ad and weather conditions.
R Do not deactivate ESP ®
.
R Only depress the accelerator pedal as far as is
necessary when pulling away. Deactivate ESP
®
in thefo llowing situations to
impr ovetraction:
R When using snow chains.
R In deep sno w.
R On sand or grav el.
% Spinning the wheels results in a cutting
action, which enhances traction.
If th e÷ ESP®
wa rning lamp lights up continu-
ousl y,ESP ®
is not available due toa malfunction.

spin. R
More drive torque is tr ansferredto the wheel

ARNI NGRisk of aquaplaning due to
insu1cient tyre tread
Insu1cient tyre tread will result in reduced
tyre grip.
The risk of aquaplaning is increased on wet
ro ads, especially when the speed of theve hi-
cle is not adap tedto suit the conditions. #
Thus, you should regula rly ch eck the
tread dep thand the condition of the
tread across the entire width of all tyres.
Minimum tread dep thfor:
R Summer ty res: 3 mm
R M+S tyres: 4 mm #
For saf etyre asons, replace the tyres
before the legall y-prescribed limit forthe
minimum tread dep thisreached. Car
