Heavy and light loads
GWARNIN G
If you res tyour foo ton th ebrak epedal while
driving, th ebrakin gsystem can overheat. This
increase sth estopping distanc eand can eve n
caus eth ebrakin gsystem to fail .There is a
ris kof an accident.
Never use th ebrak epedal as afootrest .Never
depress th ebrak epedal and th eaccelerato r
pedal at th esam etime.
!Depressing th ebrak epedal constantl y
result sin excessive and premature wear to
th ebrak epads .
If th ebrakes hav ebeen subjecte dto aheav y
load, do no tstop th evehicl eimmediately, but
drive on for ashort while .This allows th eairflow
to cool th ebrakes mor equickly.
Wet roads
If you hav edriven for alon gtime in heav yrain
without braking, there may be adelaye dreac -
tion from th ebrakes when brakin gfor th efirst
time. This may also occur after th evehicl ehas
been washed or driven through deep water.
You then hav eto depress th ebrak epedal mor e
firmly. Maintai n agreate rdistanc efrom th e
vehicl ein front.
Afte rdrivin gon awet roa dor havin gth evehicl e

th etraffic conditions. This will warm up th e
brak ediscs, thereby drying them mor equickl y
and protectin gthem against corrosion.
Limited braking perfor mance onsalt-
treated roads
If you drive on salted roads, alayer of salt resi-
due may for mon th ebrak edisc sand brak e

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:
XShift the transmission to position i.
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.
For more information on driving with snow
chains, see (
Ypage 287).
For more information on driving with summer
tires, see (
Ypage 287).
Observe the notes in the "Winter operation" sec-
tion (
Ypage 287).
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 lower gear in good time.
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 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).
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 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
Rwhen there is 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.
Cruise control lever

last stored speed
=Stores the current speed or a lower speed
?Deactivating cruise control
When you activate cruise control, the stored
speed is shown in the multifunction display for
five seconds. The speed is then permanently
displayed in the status indicator together with
the ¯ symbol.
On vehicles with a segment ring in the speed-
ometer, the segments from the currently saved speed to the end of the segment ring light up.

Storing, maintaining and calling up a
speed
Storing and maintaining a speed
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.
You can store the current speed if you are driv-
ing faster than 20 mph (30 km/h).
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 or calling up a 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
GWARNING
Keep in mind that it may take a brief moment until the vehicle has made the necessary
adjustments.
Increase or decrease the set vehicle speed to
a value that the prevailing road conditions and
legal speed limits permit. Otherwise, sudden
and unexpected acceleration or deceleration
of the vehicle could cause an accident and/orserious injury to you and others.
XTo adjust the set speed in 1 mph incre-
ments (1 km/h increments): briefly press
the cruise control lever up :to the pressure
point for a higher speed, or down ?for a
lower speed.
Every time the cruise control lever is pressed
up or down, the last speed stored is increased
or reduced.
XTo adjust the set speed in 5 mph incre-
ments (10 km/h increments): briefly press
the cruise control lever up :past the pres-
sure point for a higher speed, or down ?for
a lower speed.
Every time the cruise control lever is pressed
up or down, the last speed stored is increased or reduced.
iThe speed indicated in the speedometer
may differ slightly from the speed stored.
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 for-
wards :.
or
XBrake.

Distance Pilot DISTRONIC
General notes
Distance Pilot DI STRONIC regulates the speed
and automatically helps you maintain the dis-
tance to the veh icledetected infront. Vehicle s
are detected with the aid of the radar sensor
system. Distance Pilot DI STRONIC brakes auto-
matically to avoid excee ding the set speed or to
maintain the designated distance from the veh i-
cle infront.
You must select a lower gear ingood time on
long and steep downhillgradients, especially if
the veh icle isladen. By doing so, you willmake
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 quic kly.
If Distance Pilot DI STRONIC detects that there is
a risk of a co llision, you will be warned visually
and acoustically. Without your intervention, Dis-
tance Pilot DI STRONIC cannot prevent a co lli-
sion. An intermittent warning tone willthen
sound and the distance warning lamp willlight
up inthe instrument cluster. Brake immediately
in order to increase the distance from the veh i-
cle infront, or take evasive action, pro videdit is
safe to doso.
For Distance Pilot DI STRONIC to assist you
when driving, the radar sensor system must be
operational.
Distance Pilot DI STRONIC operates inthe range
between 0 mph (0 km/h) an
d 120 mph
(200 km/h).
Do not u

se Distance Pilot DISTRONIC while driv-
ing on roads with steep gradients. Since Distance Pilot DISTRONIC transmits radar
waves, it can resemble the radar detectors of
the responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
questions are asked about this.
