308 Operation
Driving instructions
Winter driving instructions
The most important rule for slippery or icy
roads is to drive sensibly and to avoid
abrupt acceleration, braking and steering
maneuvers. Do not use the cruise control
system under such conditions.
When the vehicle is in danger of skidding,
move gear selector lever to position N. Try
to keep the vehicle under control by cor-
rective steering action.Road salts and chemicals can adversely af-
fect braking efficiency. Increased pedal
force may become necessary to produce
the normal braking effect.
Depressing the brake pedal periodically
when traveling at length on salt-strewn
roads can bring road-salt-impaired braking
efficiency back to normal.
If the vehicle is parked after being driven
on salt-treated roads, the braking efficien-
cy should be tested as soon as possible af-
ter driving is resumed.
For more information, see “Winter driving”
(
page 351).
iFor information on driving with snow chains,
see “Snow chains” (
page 352).
Warning!G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of control loss.
Warning!G
Make sure not to endanger any other road
users when carrying out these braking ma-
neuvers.
Warning!G
If the vehicle becomes stuck in snow, make
sure snow is kept clear of the exhaust pipe
and from around the vehicle with the engine
running. Otherwise, deadly carbon monox-
ide (CO) gases may enter vehicle interior re-
sulting in unconsciousness and death.
To assure sufficient fresh air ventilation,
open a window slightly on the side of the ve-
hicle not facing the wind.
Warning!G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose. In-
dicated temperatures just above the freez-
ing point do not guarantee that the road
surface is free of ice.

ProblemPossible cause/consequenceSuggested solution
vThe yellow ESP® warn-
ing lamp comes on while
the engine is running.The ESP® has been switched off with the
ESP® switch or has been switched off due
to a malfunction.
Risk of accident!
When the ESP
® is switched off it will not
stabilize the vehicle if the system recog-
nizes that the vehicle starts to skid or that
a wheel is spinning.
The cruise control is deactivated and can-
not be switched on.
Switch the ESP® back on (page 94).
Exceptions: (
page 92).
If leaving the ESP® switched off, adapt your speed
and driving to the prevailing road, weather and
traffic conditions.
If the ESP
® cannot be switched on:
Continue driving with added caution.
Observer additional messages that may appear in
the multifunction display (
page 380).
Have the system checked at an authorized
Mercedes-Benz Center as soon as possible.
vThe yellow ESP® warn-
ing lamp flashes while
driving.The ESP® or traction control has come
into operation because of detected trac-
tion loss in at least one tire.
The cruise control is deactivatedWhen driving off, apply as little throttle as possi-
ble.
While driving, ease up on the accelerator.
Adapt your speed and driving to the prevailing
road, weather and traffic conditions.
Do not deactivate the ESP®.
Exceptions: (
page 92).
Failure to follow these instructions increases the risk
of an accident.
