Driving and parking

If you leave the engine or the auxiliary heatingrunning, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a
window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winter-proofed at a qualified
specialist workshop at the onset of winter.
Drive particularly carefully on slippery road sur-
faces. Avoid sudden acceleration, steering and
braking maneuvers. Do not use cruise control or Distance Pilot DISTRONIC.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the transmission to position N.
XTry to bring the vehicle under control using
corrective steering.
The outside temperature indicator is not
designed to serve as an ice-warning device and is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in
wooded areas or on bridges.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
For more information on driving with snow
chains, see (
Ypage 285).
For more information on driving with summer
tires, see (
Ypage 284).
Observe the notes in the "Winter operation" sec-
tion (
Ypage 284).
Driving systems
Cruise control
General notes
Cruise control maintains a constant road speed
for you. It brakes automatically in order to avoid
exceeding the set speed. On long and steep
downhill gradients, especially if the vehicle is
laden, you must select a low gear in good time.
You need to have selected manual drive pro-
gram M(
Ypage 135). By doing so, you will make
use of the braking effect of the engine. This relieves the load on the brake system and pre-
vents the brakes from overheating and wearing
too quickly.
When the engine is running, you can use the
cruise control lever to limit the speed to any
speed between 20 mph (30 km/h) and the tech-
nically permitted maximum speed of the vehicle.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a steady
speed for a prolonged period.
The speed indicated in the speedometer may
differ slightly from the speed stored.
Important safety notes
If you fail to adapt your driving style, cruise con-
trol can neither reduce the risk of an accident
nor override the laws of physics. Cruise control
cannot take into account the road, traffic and
weather conditions. Cruise control is only an
aid. You are responsible for the distance to the
vehicle in front, for vehicle speed, for braking in
good time and for staying in your lane.
Do not use cruise control:
Rin road and traffic conditions which do not
allow you to maintain a constant speed e.g. in
heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rin poor visibility, e.g. due to fog, heavy rain or
snow
If there is a change of drivers, advise the new
driver of the speed stored.

Driving and parking

=Deactivates cruise control
?Activates at the current speed/last stored
speed
When you activate cruise control, the stored
speed is shown in the multifunction display for
five seconds.
Activation conditions
To activate cruise control, all of the following
activation conditions must be fulfilled:
Rthe electric parking brake must be released.
RESP®must be active, but not intervening.
Rthe transmission must be in position D.
Storing, maintaining and calling up a
speed
Storing and maintaining the current
speed
You can store the current speed if you are driv-
ing faster than 20 mph (30 km/h).
XAccelerate the vehicle to the desired speed.
XBriefly press the cruise control lever up :or
down ;.
XRemove your foot from the accelerator pedal.
Cruise control is activated. The vehicle auto-
matically maintains the stored speed.
iCruise control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by auto-
matically applying the brakes.
Storing the current speed or calling up the
last stored speed
GWARNING
If you call up the stored speed and it differs
from the current speed, the vehicle acceler-
ates or decelerates. If you do not know the
stored speed, the vehicle could accelerate or brake unexpectedly. There is a risk of an acci-
dent.
Pay attention to the road and traffic condi-
tions before calling up the stored speed. If you
do not know the stored speed, store the
desired speed again.
XBriefly pull the cruise control lever towards
you ?.
XRemove your foot from the accelerator pedal.
The first time cruise control is activated, it
stores the current speed or regulates the
speed of the vehicle to the previously stored
speed.
Setting a speed
Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the speed set.
XTo adjust the set speed in10 km/hincre-
ments: briefly press cruise control lever :up
beyond the pressure point for a higher speed,
or down ;for a lower speed.
or
XKeep the cruise control lever pressed beyond
the point of resistance until the desired speed
is set. Press cruise control lever up :for a
higher speed or down ;for a lower speed.
XTo adjust the set speed in1 km/hincre-
ments:briefly press cruise control lever up :
to the pressure point for a higher speed or
down ;for a lower speed.
or
XKeep the cruise control lever pressed to the
point of resistance until the desired speed is
set. Press cruise control lever up :for a
higher speed or down ;for a lower speed.
iCruise control is not deactivated if you
depress the accelerator pedal. For example, if
you accelerate briefly to overtake, cruise con-
trol adjusts the vehicle's speed to the last
speed stored after you have finished overtak-
ing.
Deactivating cruise control
There are several ways to deactivate cruise con-
trol:
XBriefly press the cruise control lever forwards
=.
or
XBrake.
Cruise control is automatically deactivated if:
Rthe vehicle is secured with the electric park-
ing brake
Ryou are driving at less than 20 mph (30 km/h)
