Driving on wet roads
Hydroplaning If water has accumulated to a certain depth on
the road surface, there is a danger of hydro-
planing occurring, even if:
R you drive at low speeds
R the tires have adequate tread depth
For this reason, in the event of heavy rain or in
conditions in which hydroplaning may occur,
you must drive in the following manner:
R lower your speed
R avoid ruts
R avoid sudden steering movements
R brake carefully
Driving on flooded roads !
Do not drive through flooded areas. Check
the depth of any water before driving through
it. Drive slowly through standing water. Oth-
erwise, water could enter the vehicle interior
or engine compartment. It can then damage
the engine's or automatic transmission's
electronic components. It can also be sucked
in by the engine's air intake connection and
cause engine damage. Winter driving
G
WARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury. If you leave the engine or the auxiliary heating
running, 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.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Shift the transmission to position 005C.
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. The vehicle could
skid if you fail to adapt your driving style. Always
adapt your driving style and drive at a speed to
suit the prevailing weather conditions.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.

tires (Y page 265).
Observe the notes in the "Winter operation" sec-
tion (Y page 265). 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. Change into a lower
gear in good time on long and steep downhill
gradients. This is especially important if the
vehicle is laden. By doing so, you will make use of the braking effect of the engine. This relieves
the load on the brake system and prevents the 134
Driving syste
msDriving and parking

brakes from overheating and wearing too
quickly.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a steady speed for a prolonged period. You can store any
road speed above 20 mph (30 km/h).
Cruise control lever 0043
Activates or increases speed
0044 Activates at the current speed or last stored
speed
0087 Activates or reduces speed
0085 Deactivates cruise control
When you activate cruise control, the stored
speed is shown in the multifunction display for
five seconds. In addition, the 00ECsymbol
appears in the multifunction display.
Speedometer with segments: when cruise
control is activated, the segments from the
stored speed to the end of the scale light up.
Storing and maintaining the current
speed You can store the current speed if you are driv-
ing faster than 20 mph (30 km/
h).X
Accelerate the vehicle to the desired speed.
X Briefly press the cruise control lever up 0043or
down 0044.
X Remove your foot from the accelerator pedal.
Cruise control is activated. The vehicle auto-
matically maintains the stored speed.
i Cruise 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, maintaining and calling up a
speed G
WARNING
If you call up the stored speed and it is lower
than the current speed, the vehicle deceler-
ates. If you do not know the stored speed, the vehicle could decelerate unexpectedly. There
is a risk of an accident.
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. X
Briefly pull the cruise control lever towards
you 0043.
X Remove 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. Driving systems
135Driving and parking Z

Setting a speed
Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the speed set.
X Press the cruise control lever up 0043for a
higher speed or down 0044for a lower speed.
X To adjust the set speed in 1 mph incre-
ments (1 km/h increments):
briefly press
the cruise control lever up 0043or down 0044to
the pressure point.
Every time the cruise control lever is pressed
up 0043 or down 0044the last speed stored is
increased or reduced.
X To adjust the set speed in 5 mph incre-
ments
(10 km/h increments): briefly press
the cruise control lever up 0043or down 0044
beyond the pressure point.
Every time the cruise control lever is pressed
up 0043 or down 0044the last speed stored is
increased or reduced.
i Cruise control is not deactivated if you
depress the accelerator pedal. If you acceler-
ate to overtake, cruise control adjusts the
vehicle's speed to the last speed stored after
you have finished overtaking.
Deactivating cruise control There are several ways to deactivate cruise con-
trol:
X Briefly press the cruise control lever for-
wards 0043.
or
X Brake.
Cruise control is automatically deactivated
under the following conditions:
R the electric parking brake is applied.
R you are driving slower than 20 mph
(30 km/h).
R if ESP ®
intervenes or you deactivate ESP ®
.
R you shift the transmission to position 005C
while driving.
If cruise control is deactivated, a warning tone
sounds. You will see the Cruise Control Off Cruise Control Off
message in the multifunction display for approx-
imately five seconds.
i When you switch off the engine, the last
speed stored is cleared. Active Distance Assist DISTRONIC
General notes Active Distance Assist DISTRONIC regulates the
speed and automatically helps you maintain the
distance from the vehicle detected in front.
Vehicles are detected with the aid of the radar
sensor system. Active Distance Assist
DISTRONIC brakes automatically so that the set
speed is not exceeded.
Change into a lower gear in good time on long
and steep downhill gradients. This is especially
important if the vehicle is laden. By doing so, you will make use of the braking effect of the engine.
This relieves the load on the brake system and
prevents the brakes from overheating and wear- ing too quickly.
If Active Distance Assist DISTRONIC detects
that there is a risk of a collision with the vehicle
in front, you will be warned visually and audibly.
Active Distance Assist DISTRONIC cannot pre-
vent a collision without your intervention. An
intermittent warning tone will then sound and
the distance warning lamp will light up in the
instrument cluster. Brake immediately in order
to increase the distance to the vehicle in front or take evasive action provided it is safe to do so. 136
