Selector lever in A/M
Switch between Automatic and Manual
mode.
In manual mode, gears can be selected
manually by moving the selector lever
to
+or
-. The currect gear is indicated in
the transmission display.
If the engine speed is too low the manual
transmission automated will automatically
shift to a lower gear even in Manual mode.
This prevents the engine from stalling. Selector lever in + or -
If a higher gear is selected when the
running speed is too low, or a lower gear
when the speed is too high, the gear
selection will not take place. This prevents
the engine from running at too low or too
high revs.
Gears can be skipped by jogging the
selector lever repeatedly
at short intervals.
When the vehicle is in automatic mode, the
manual transmission automated shifts to
manual mode by moving the selector lever
to position
+ or
-. The correct gear is
indicated on the transmission display.
Selector lever in R
Reverse gear. Engage only when vehicle is
stationary.
Press button on selector lever, select R. The
transmission display shows "R".
If R is selected when the vehicle is in motion,
"R" flashes in the transmission display and
no gear is engaged. Stopping the vehicle
In Automatic or Manual mode, when the
vehicle has stopped first gear (with Winter
mode engaged, second gear) is engaged
automatically and the
clutch released. In R
reverse remains engaged.
If a warning signal sounds when the
driver’s door is opened (foot brake not
depressed), move the selector lever to N
and apply the hand brake.
When stopping on gradients, engage the
hand brake or depress the brake pedal. To
prevent overheating of the clutch, do not
increase engine speed to ensure smooth
idling when in gear.
Switch off engine if stopping for a lengthy
period, e.g. in traffic jams or at level
crossings.
Electronically controlled driving
programmes in automatic mode
z Following a cold start, the operating
temperature program automatically
increases the engine revolutions to bring
the catalytic converter to the required
temperature.
z The adaptive program automatically
selects the gear according to the driving
conditions, e.g. increased load and
gradients.
+
Shift to a higher gear.
-
Shift to a lower gear.

Catalytic converter, exhaust
gassesCatalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gas, such as carbon monoxide
(CO), hydrocarbons, (CH) and nitrous
oxide (NO
x). Fuel grades other than those listed on
pages 139, 220 (e. g. LRP = Lead
Replacement Petrol or leaded fuel) could
damage the catalytic converter or
electronic components.
z
In the event of misfiring, uneven engine
running, a clear reduction in engine
performance or other unusual problems,
have the cause of the fault rectified by a
workshop as soon as possible. In an
emergency, driving can be continued for
a short period, keeping vehicle speed
and engine speed low.
This does not apply when the Electronic
Stability Program (ESP®
Plus
3) kicks in
3 146.
z If unburnt fuel enters the catalytic
converter of a petrol engine, this may
result in overheating and irreparable
damage to the catalytic converter.
You should therefore avoid
unnecessarily long use of the starter
when starting off, running the tank dry
and starting the engine by pushing or
towing.

Controlling exhaust emission
Design measures, primarily in the fuel
injection system and ignition system zones
in combination with the catalytic converter,
the amount of hazardous substances in the
exhaust emissions, such as carbon
monoxide (CO), hydrocarbons (CH) and
nitrogen oxides (NO
x), are reduced to a
minimum.
Caution
Damage to the catalytic converter or the
vehicle may result if the following points
are not observed.
