downshift, selecting the most
appropriate gear automatically.
If R is selected, reverse gear is
engaged. The vehicle starts to move
when the brake pedal is released. To
start off quickly, release the brake
pedal and accelerate immediately
after engaging a gear.
Move the selector lever towards A/M
to engage automatic mode; the
transmission shifts to other gears
automatically, dependent on driving conditions.
To engage manual mode, move the selector lever towards A/M. The
current gear will appear in the
transmission display.
Stopping the vehicle
In automatic or manual mode,
first gear is engaged and the clutch is
released when the vehicle is stopped. In R, reverse gear remains engaged.
When the vehicle is at a standstill, if
the engine is running and a forward or
reverse gear is engaged, a warning
chime will sound and the
transmission automatically shifts to
N in certain situations.
When stopping on gradients, engage
parking brake or depress the brake pedal. To prevent overheating of theclutch, an intermittent audible
warning chime may sound as a signal
to depress the brake pedal or apply
the parking brake.

124Driving and operatingSwitch off engine if stopping for a
lengthy period, e.g. in traffic jams.
Engine braking
Automatic mode
When driving downhill, the manual
transmission automated does not
shift into higher gears until a fairly
high engine speed has been reached. It shifts down in good time when
braking.
Manual mode
To utilise the engine braking effect, select a lower gear in good time when
driving downhill.
Rocking the vehicle Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud, snow or a hole. Move the
selector lever between R and A/M (or
between + and -) in a repeat pattern,
while applying light pressure to the
accelerator pedal. Do not race the
engine and avoid sudden
acceleration.Parking
Apply the parking brake. The most recently engaged gear (see
transmission display) remains
engaged.Caution
Do not leave the vehicle with the
transmission in position N.
When the ignition is switched on, a
warning chime will sound when the
vehicle is parked if the transmission is still in N.
When the ignition is switched off, the transmission no longer responds to
movement of the selector lever.
Manual mode If engine speed is too low, the
transmission automatically shifts to a
lower gear.
In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions. If engine
speed is too high, the transmission
only switches to a higher gear via
kickdown 3 124.
When gearshifting is recommended
to improve fuel economy, control
indicator [ or Ò illuminates in the
Driver Information Centre 3 85.
Electronic driving programmes
Eco mode E
When automatic mode is engaged,
the Eco mode can be selected to
reduce fuel consumption.

Driving and operating125Eco mode selects the most suitable
gear depending on the speed of the
vehicle, the engine speed and the
intensity with which the accelerator is
pressed.
Activation
Press E on the selector lever housing.
Control indicator E is shown in the
transmission display to indicate
activation.
Deactivation
Eco mode is switched off by:
● pressing E again
● switching to manual mode
In order to protect the transmission at
extremely high clutch temperatures,
an intermittent audible warning chime may sound. In such cases, depress
the brake pedal, select N and apply
the parking brake to allow the clutch
to cool down.
Kickdown If the accelerator pedal is pressed
past the pressure point, the
transmission shifts to a lower geardepending on engine speed. Full
engine power is available for
acceleration.
If engine speed is too high the
transmission switches to a higher
gear, even in manual mode. Without
kickdown this automatic shift is not
effected in manual mode.
Fault
In the event of a fault, control indicator s is shown in the transmission
display.
Continued driving is possible,
provided the vehicle is driven with
care and anticipation. A warning
message may appear in the Driver
Information Centre in conjunction with
a warning chime 3 95.
Note
The volume of the warning chime
can also be adjusted via the Driver
Information Centre 3 90.
Have the cause of the fault remedied by a workshop.

126Driving and operatingBrakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 84.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting off the system performs
a self-test which may be audible.
Fault
In the event of a fault, control indicator
u illuminates in the instrument
cluster. Depending on version, a
corresponding warning message,
e.g. ABS unavailable , may also be
displayed in the Driver Information Centre 3 90.9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Control indicator u 3 84.

Centre 3 90. Seek the assistance of
a workshop to have the fault remedied.
The Hill start assist is not active
during an Autostop.
Stop-start system 3 116.Ride control systems
Traction Control system The Anti-Slip Regulator (ASR) is a
component of the Electronic Stability
Control (ESC).
ASR improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
ASR is operational after each engine
start as soon as the control indicator
R extinguishes.
When ASR operates, R flashes.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.

Driving and operating129Deactivation
ASR can be switched off when
spinning of drive wheels is required:
press ASR OFF briefly.
LED in button illuminates and,
depending on version, a
corresponding message, e.g. ASR
disconnect , may also be displayed in
the Driver Information Centre 3 90.
ASR is reactivated by pressing
ASR OFF again.
ASR is also reactivated the next time
the ignition is switched on.
Fault
ASR will switch off automatically in the event of a fault. Control indicator
R will illuminate in the instrument
cluster. Depending on version, a
corresponding message, e.g. ESP
unavailable , may also appear in the
Driver Information Centre 3 90.
Have the cause of the fault remedied by a workshop.
Control indicator R 3 85.
Electronic Stability Control
Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip. It also
prevents the drive wheels from
spinning.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the wheels are braked individually. This
considerably improves the driving
stability of the vehicle on slippery road
surfaces.
ESC is operational after each engine
start as soon as control indicator R
extinguishes.
When ESC operates, R flashes.
The ESC system is automatically
activated when the vehicle is started
and cannot be deactivated.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.

134Driving and operatingFuel
Fuel for petrol engines Only use unleaded fuel that complies
with European standard EN 228 or E DIN 51626-1 or equivalent.
The engine is capable of running with fuel that contains up to 10% ethanol
(e.g. named E10).
Use fuel with the recommended
octane rating 3 182. A lower octane
rating can reduce engine power and
torque and slightly increases fuel
consumption.Caution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.
Caution
Use of fuel that does not comply to EN 228 or E DIN 51626-1 or
equivalent can lead to deposits or
engine damage.
Caution
Use of fuel with a lower octane
rating than the lowest possible
rating could lead to uncontrolled combustion and engine damage.
The engine-specific requirements are
given in the engine data overview
3 182. A country-specific label at the
fuel filler flap can supersede the
requirement.
Fuel for diesel engines
Only use diesel fuel that complies
with EN 590 and which has a sulphur
concentration of max. 10 ppm.
In countries outside the European
Union use Euro-Diesel fuel with a
sulphur concentration below 50 ppm.
Caution
Use of fuel that does not comply to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and may affect
your warranty.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
Fuel for natural gas operation
Use natural gas with a methane
content of approx. 78 - 99%. L-gas
(low) has approx. 78 - 87% and H-gas (high) has approx. 87 - 99%. Biogas
with the same methane content can
also be used if it has been chemically
prepared and desulphurised.
Only use natural gas or biogas that complies with DIN 51624.
Liquid gas or LPG must not be used.

automatically engaged. Control
indicator Y illuminates in the Driver
Information Centre 3 90 until the
ignition is switched off.
When switching automatically
between petrol or gas operation, a
brief delay of engine tractive power
may be noticeable.
Every six months run the petrol tank
down until control indicator §
illuminates and then refuel. This is
necessary to maintain fuel quality as
well as system function necessary for
petrol operation.
Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
Refuelling
