Driving and operating127During an Autostop, the heating and
brake performance will be
maintained.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled.
● The stop-start system is not manually deactivated.
● The driver's door is closed or the driver's seat belt is fastened.
● The vehicle battery is sufficiently charged and in good condition.
● The engine is warmed up.
● The engine coolant temperature is not too high.
● The engine exhaust temperature is not too high, e.g. after driving
with high engine load.
● The ambient temperature is not too low or too high.
● The climate control system allows an Autostop.
● The brake vacuum is sufficient.● The self-cleaning function of the exhaust filter is not active.
● The vehicle was driven at least at
walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.
Notice
The Autostop may be inhibited for
several hours after a battery
replacement or reconnection.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details 3 111.
If an autostop is temporarily not
available, D flashes green 3 87.
Immediately after driving at a higher
speed an Autostop may be inhibited.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.Power saving measures
During an Autostop, several electrical
features such as auxiliary electric
heater or rear window heating are
disabled or switched to a power
saving mode. The fan speed of the
climate control system is reduced to
save power.
Restart of the engine by the driver
Vehicles with manual transmission
Depress the clutch pedal without depressing the brake pedal to restart
the engine.
Vehicles with automatic transmission The engine is restarted if
● the brake pedal is released while
the selector lever is in position D
or M
● or the brake pedal is released or the selector lever is in position N
when the selector lever is moved
to position D or M
● or the selector lever is moved to position R.

Driving and operating1339. Unscrew the hose from the fillerneck.
10. Mount the protective cap and turn
clockwise until it engages.
Notice
Dispose of AdBlue canister
according to environmental
requirements. Hose can be reused
after flushing with clear water before AdBlue dries out.Automatic transmission
The automatic transmission permits
automatic gearshifting (automatic
mode) or manual gearshifting
(manual mode).
Manual shifting is possible in manual
mode by tapping the selector lever to + or - 3 134.
Transmission display
The mode or selected gear is shown
in the Driver Information Centre.
D and the number of the engaged
gear indicates automatic mode.
M and the number of the selected
gear indicates manual mode.
R indicates reverse gear.
N indicates neutral position.
P indicates park position.
Gear selection
Move the selector lever in the shifting
gate as shown in the illustration
above.

Driving and operating135In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions.
Gear shifting 3 85.
Electronic driving programmes
● Following a cold start, the operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● Special programmes automatically adapt the shifting
points when driving up inclines or
down hills.
● In snowy or icy conditions or on other slippery surfaces, the
electronic transmission control
enables the driver to select
manually first, second or third
gear for starting off.Kickdown
Pressing down the accelerator pedal
beyond the kickdown detent will lead
to maximum acceleration
independent of selected driving
mode. The transmission shifts to a lower gear depending on enginespeed.
Fault In the event of a fault a message is
displayed in the Driver Information
Centre.
Vehicle messages 3 95.
Electronic transmission control
enables only third gear. The
transmission no longer shifts
automatically.
Do not drive faster than 62 mph.
Have the cause of the fault remedied by a workshop.
Interruption of power supply In the event of an interruption of
power supply, the selector lever
cannot be moved out of the P
position.If the vehicle battery is discharged,
start the vehicle using jump leads
3 208.
If the vehicle battery is not the cause
of the fault, release the selector lever.
1. Apply the parking brake.
2. Release the selector lever trim from the centre console. Poke
with a finger into the leather socket below the selector lever
and push the trim upwards.

136Driving and operating3. Push down the button and movethe selector lever out of P. Have
the cause of the power supply
interruption remedied by a
workshop.
4. Mount the selector lever trim onto
the centre console and refit.Manual transmission
To engage reverse on 5-speed
transmission, depress the clutch
pedal and move the selector lever to
the right and rear.
To engage reverse on 6-speed
transmission, depress the clutch
pedal, pull the ring under the selector
lever and move the selector lever
quite to the left and front.
If the gear does not engage, set the
lever to neutral, release the clutch
pedal and depress again; then repeat gear selection.
Do not slip the clutch unnecessarily. When operating, depress the clutch pedal completely. Do not use the
pedal as a foot rest.

140Driving and operatingESC and traction control system are
also reactivated the next time the
ignition is switched on.
Fault
If there is a fault in the system, the control indicator b illuminates
continuously and a message appears in the Driver Information Centre. The
system is not operational.
Have the cause of the fault remedied
by a workshop.Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver stays in full control of
the vehicle and accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation and follow applicable
traffic rules.
Cruise control
The cruise control can store and
maintain speeds above 25 mph.
Additionally at least the third gear
must be engaged on manual
transmission.
Additionally position D or the second
or a higher gear in position M must be
selected on automatic transmission.
Deviations from the stored speeds
may occur when driving uphill or
downhill.
The system maintains the vehicle
speed at the preset speed by the
driver, without any action on the
accelerator pedal.
The preset speed can be exceeded
temporarily by pressing the
accelerator pedal firmly.
The status and preset speed is
displayed in the Driver Information Centre.
Do not use the cruise control if it is not advisable to maintain a constant
speed.
Control indicator m 3 88.

142Driving and operatingAdopting speed by the speed limit
recognition
The intelligent speed adaptation
informs the driver when a speed limit
is detected by the speed limit
recognition. The detected speed limit
can be used as new value for the
cruise control.
Using the camera at the top of the
windscreen, this system detects and
reads speed limit and end of speed
limit signs.
If the cruise control is active: ● in the uplevel Driver Information Centre the recognised speed
limit will be displayed and MEM
illuminates.
● in the midlevel Driver Information
Centre the recognised speed
limit will be displayed on the
digital speed indication page
along with an instruction
message.
Press MEM on the steering wheel to
request saving of the suggested
speed.Press MEM on the steering wheel
once more to confirm and save the
new speed setting.
This speed is the new value for the
cruise control.
This function can be deactivated or activated in the personalisation menu
3 96.
Exceeding the set speed
Vehicle speed can be increased by
depressing the accelerator pedal. When the accelerator pedal is
released, the previously stored speed
is resumed.
Deactivation of the functionality
Press Ñ: cruise control is in pause
mode and a message is displayed. The vehicle is driven without cruise
control.
Cruise control is deactivated, but not
switched off. Last stored speed
remains in memory for later speed
resume.Cruise control is deactivated
automatically when:
● The brake pedal is depressed.
● Vehicle speed is below 25 mph.
● The Traction Control system or Electronic Stability Control is
operating.
● The manual transmission is in N,
first or second gear.
● The automatic transmission is in position M and first gear.
Resume stored speed
Move thumb wheel to RES/+ at a
speed above 25 mph. The stored
speed will be obtained.
Switching off the system
Press m: the cruise control mode is
deselected and the cruise control
indication extinguishes in the Driver
Information Centre.
Pressing ß to activate the speed
limiter deactivates cruise control.
Switching off the ignition cancels any
programmed speed value.
