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
accelerating 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.

Storing and maintaining the current

While cruise control is active, you can set the
current speed starting from 20 mph (30 km/h).
XAccelerate the vehicle to the desired
speed.
XPress switch 0044(®) and release it.
XRemove your foot from the accelerator
pedal.
Cruise control is activated. The vehicle
automatically maintains the stored speed.
0085 SET
is shown in the multifunction
display.
iCruise control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out.
On downhill gradients, only the engine's
braking effect is available. You have to
operate the brakes yourself to reduce
speed. This interrupts cruise control.
Calling up the last speed stored
GWARNING
If you call up the stored speed and it is
different to the current speed, the vehicle
will accelerate. If you are not aware of the
stored speed, the vehicle may accelerate
unexpectedly. There is a risk of an acci-
dent.
Pay attention to the road and traffic con-
ditions before calling up the stored speed. If you do not know the stored speed, store
the desired speed again.
XPress button 0087° and release it.
Cruise control is activated and adjusts the vehicle's speed to the last speed stored.
XRemove your foot from the accelerator
pedal.
iWhen you switch off the engine, the last
speed stored is cleared.
Increasing or decreasing the speed
In order to be able to increase or decrease the
speed, a speed must already have been stored.
iCruise control is not deactivated if you
depress the accelerator pedal. For exam-
ple, if you accelerate briefly to overtake,
cruise control adjusts the vehicle's speed
to the last speed stored after you have fin-
ished overtaking.

Useful information
i
This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's Man- ual. Country-specific differences are pos-
sible. Bear in mind that your vehicle may
not feature all functions described here.
This also applies to safety-relevant sys-
tems and functions.
iRead the information on qualified spe-
cialist workshops: (Ypage 20).
Important safety notes
GWARNING
If you operate information systems and
communication equipment integrated in
the vehicle while driving, you will be dis- tracted from traffic conditions. You could
also lose control of the vehicle. There is a
risk of an accident.
Only operate the equipment when the traf-
fic situation permits. If you are not sure
that this is possible, park the vehicle pay-
ing attention to traffic conditions and
operate the equipment when the vehicle is
stationary.
You must observe the legal requirements for
the country in which you are currently driv-
ing when operating the on-board computer.
GWARNING
If the instrument cluster has failed or mal- functioned, you may not recognize function
restrictions in systems relevant to safety.
The operating safety of your vehicle may beimpaired. There is a risk of an accident.
Drive on carefully. Have the vehicle
checked at a qualified specialist workshop
immediately.
The on-board computer only shows display
messages and/or warnings from certain sys-
tems in the display. You should therefore
make sure your vehicle is operating safely at all times. Otherwise, you may cause an acci-
dent by driving a vehicle that is not operat-
ing reliably.
If the operating safety of your vehicle
impaired, park the vehicle as soon as possi-
ble paying attention to road and traffic con-
ditions. Contact a qualified specialist work-
shop.
Read and follow the notes in the overview of
warning and indicator lamps in the instru-
ment cluster (
Ypage 24).
Displays and operation
Instrument cluster lighting
Instrument cluster lighting includes illumi-
nation of the instrument cluster, the addi-
tional instruments on the dashboard, the dis-
plays and the controls.
The instrument cluster lighting is switched
automatically between day and night lighting
depending on the ambient light conditions
(
Ypage 67).
You can additionally set the brightness of the
instrument cluster lighting to different lev-
els in the on-board computer (
Ypage 115).
Speedometer
If you turn the key to position 2in the igni-
tion lock, the warning and indicator lamps in
the instrument cluster will briefly light up
for a lamp test. During the lamp test, the
illuminated speedometer needle moves in the
speedometer.
The display can show a digital speedometer.
The digital speedometer can be hidden/
displayed and its speed unit selected
(
Ypage 115).
Outside temperature display
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
Bear in mind that the outside temperature
display indicates the temperature measured
and does not record the road temperature.
The outside temperature is displayed on the
far right in the top bar.

Changes in the outside temperature are dis-
played after a short delay.
You can set the temperature unit of the out-
door temperature display (

When the fuel level falls below the reserve
range of 5.0 l, the last illuminated segment of
the fuel display will flash and a warning tone
will sound. Reserve fuel display 0043will also
appear. The reserve fuel display shows the
numeric value of the remaining fuel level in
0.5 l increments.
In addition:
R00B4 symbol 0085also appears in yellow
Ra display message is also shown
(Ypage 125).
Dashboard instruments
!Do not drive in the overrevving range, as
this could damage the engine.
HEnvironmental note
Avoid driving at high engine speeds. This
unnecessarily increases the fuel consump-
tion of your vehicle and harms the envi-
ronment as a result of increased emissions.
The overrevving range of the engine is shown with dashed lines in the orange marking of
rev counter 0043. The fuel supply is interrupted
to protect the engine when the overrevving
range is reached.
Dashboard clock 0044is synchronized with the
clock in the on-board computer.
Rev counter 0043, together with dashboard
clock 0044, can be rotated approximately 60° on
the dashboard.
You can additionally set the brightness of the
instrument cluster lighting to different lev-
els (
Ypage 115).

Display messages
Introduction
Display messages with graphic symbols are simplified in the Operator's Manual and may differ
from the symbols in the display. The display shows high-priority messages in red. For certain
display messages a warning tone also sounds.
Please respond in accordance with the display messages and follow the additional notes in this
Operator's Manual.
You can use the0076button on the multifunction steering wheel to hide low-priority mes-
sages. The display messages are stored in the message memory and can be called up as for as
long as the ignition remains switched on (
Ypage 113). When the ignition is turned off, the
message memory is deleted and no display messages are stored. The cause of a display message
should be remedied as soon as possible.
High-priority display messages cannot be hidden. The multifunction display shows these
messages continuously until the causes for the messages have been remedied.
