Haptic accelerator pedal General notes The haptic accelerator pedal helps you to
reduce the fuel consumption and emissions of
your vehicle.
There are two different functions available for
this purpose: R
an additional point of resistance in E-MODE
operating mode ( Y
page 243)R
a double impulse in E+ operating mode
( Y
page 250)
Additional point of resistance in the hap-
tic accelerator pedal The maximum available electric performance is
indicated by a tangible point of resistance in the
haptic accelerator pedal.
The additional point of resistance is available in
E-MODE operating mode ( Y
page 243).
If you depress the haptic accelerator pedal
beyond the pressure point, the combustion
engine is switched on.
Double pulses in the haptic accelerator
pedal
A tangible double pulse in the haptic accelerator
pedal gives you a recommendation to release
the accelerator pedal. The combustion engine
can switch off and be disconnected from the
drive train (overrun mode).
The double pulse is available in drive program E+
( Y
page 250). After the accelerator pedal has been released,
the coasting characteristics of the vehicle are
adapted to the traffic conditions.
To avo id getting too close to the vehicle in front,
y
ou must apply the brakes manually when nec-
essary.
Driving tips General driving tips Drive carefully and maintain a safe distance
from the vehicle in front. Avoid frequent and
sudden acceleration as well as abrupt braking.
During partial electric driving, pulling away and
acceleration, the electric motor supports the
internal combustion engine.
During overrun in transmission position D and
braking, the electric motor will operate as a gen-
erator.
Further information on the ECO start/stop func-
tion ( Y
page 252).
Additional driving tips ( Y
page 192).
Stationary vehicle If the vehicle is stopped, the combustion engine
is, for the most part, switched off. Automatic
climate control continues to function. The elec-
tromechanically assisted steering gear allows
you to use the power steering without reduced
comfort.
Acceleration Depending on the operating mode, pulling away
and driving under low load conditions are per-
formed: R
entirely by electric propulsion R
in combination with the internal combustion
engine
When accelerating at an increased or full load,
boost mode is utilized. The electric motor sup-
ports the internal combustion engine by provid-
ing additional torque when the accelerator is
depressed rapidly.
Overrun mode or braking
There are three possible operating modes when
the hybrid vehicle is decelerating: R
energy recovery takes place even when the
vehicle is decelerating purely in overrun mode
( Y
page 240). The electric motor operates asPLUG ‑ IN HYBRID operation 251
Driving an d parking Z

a generator and stores the recovered energy
in the high-voltage battery R
when the brakes are applied lightly, the vehi-
cle is slowed down further by the electric
motor. This increases the energy recovery
taking place ( Y
page 240). The electric motor
operates as a generator and stores the recov-
ered energy in the high-voltage battery R
when the brakes are applied with greater
force, the service brakes are also used to slow
the vehicle down. The two systems work
together
Urban driving Energy is recuperated during frequent deceler-
ation and stopping in city traffic.
The vehicle can be driven by the electric motor
alone up to a speed of approximately 81 mph
(130 km/h).
The vehicle is driven by the electric motor alone
only when all conditions for the automatic
engine switch-off are fulfilled.
Further information on the automatic engine
switch-off ( Y
page 252).
Driving on inter-urban roads The following phases are possible when driving
on inter-urban roads: R
rapid acceleration (boost mode) R
constant energy consumption R
energy recuperation R
electric operation mode
A great deal of recovered energy may be avail-
able, depending on the route profile. This
reduces consumption and emissions.
Highway driving
During highway driving, fuel consumption and
emissions are favorably influenced in partic ular
by reduced power losses.
The internal combustion engine will be switched
off automatically, if: R
the driver removes his or her foot from the
accelerator pedal in drive program E and a
speed of 81 mph (130 km/h) is not exceeded R
the driver removes his or her foot from the
accelerator pedal in drive program E+ and a
speed of 112 mph (180 km/h) is not excee-
ded
Further information on the automatic engine
switch-off ( Y
page 252). ECO start/stop function General notes The ECO start/stop function switches the inter-
nal combustion engine off automatically when
the vehicle stops moving and at high speeds
( Y
page 253).
All vehicle systems remain active, e.g. the auto-
matic climate control.
The ECO start/stop function is only available in
drive programs E and E+ . Electric-only operation
is only possible in drive programs E and E+ .
Additional information for drive programs E and
E+ ( Y
page 250).
Automatic engine switch-off The engine is switched off automatically, includ-
ing when: R
the driver removes his or her foot from the
accelerator pedal in drive program E and a
speed of 81 mph (13 0 km/ h) is not exceeded

ded ( Y
page 253) R
the engine has reached its operating temper-
ature R
the driver’s seat belt is fastened and the
driver’s door is closed R
the driver only slightly depresses the accel-
erator pedal in order to, for example, maintain
the current speed for a limited distance R
the hood is closed and engaged properly R
the high-voltage battery is charged suffi-
ciently R

Important notes on tire pressure
G WARNIN G
If th e tire pressur e drops repeatedly, th e
wheel, valv e or tire may be damaged. Tir e
pressur e that is to o low may result in a tire
blow-out . Ther e is a ris k of an accident.R
Chec k th e tire for foreign objects .R
Chec k whether th e whee l is losing air or th e
valv e is leaking .
If you are unable to rectify th e damage, con-
tac t a qualified specialist workshop.
G WARNIN G
If you fit unsuitable accessories onto tire
valves, th e tire valves may be overloaded and
malfunction , whic h can caus e tire pressur e
loss . Due to their design , retrofitte d tire pres-
sur e monitors keep th e tire valv e open . This
can also result in tire pressur e loss . Ther e is a
ris k of an accident.
Only screw th e standard valv e cap or other
valv e cap s approve d by Mercedes-Ben z for
your vehicl e onto th e tire valve.
Use a suitable pressur e gauge to chec k th e tire
pressure. The outer appearanc e of a tire does
no t permit any reliable conclusio n about th e tire
pressure. On vehicles equipped wit h th e elec -
tronic tire pressur e monitor, th e tire pressur e
can be checke d in th e on-board computer.
The tire temperature and pressur e increas e
when th e vehicl e is in motion . This is dependen t
on th e driving spee d and th e load.
Therefore, you should only correc t tire pres-
sures when th e tires are cold.
The tires are cold: R
if th e vehicl e has been parked wit h th e tires
out of direct sunligh t for at least three hour s
and R
if th e vehicl e has no t been driven further than
1 mile (1. 6 km)
The tire temperature changes depending on th e
outside temperature, th e vehicl e spee d and th e
tire l oad. If th e ti
re temperature changes by
18 ‡ (10 †), th e tire pressur e changes by
approximately 10 kP a (0. 1 bar/1.5 psi) . Tak e
this int o accoun t when checkin g th e pressur e of
warm tires . Only correc t th e tire pressur e if it is to o low for th e curren t operating conditions. If
you chec k th e tire pressur e when th e tires are
warm , th e resulting value will be higher than if
th e tires were cold. This is normal. Do no t
reduce th e tire pressur e to th e value specifie d
for cold tires . The tire pressur e would otherwise
be to o low.
Observ e th e recommended tire pressures for
cold tires : R

Underinflated or overinflated tires
Underinflated tires
G WARNIN G
Tires wit h pressur e that is to o low can over-
heat and burs t as a consequence . In addition ,
they also suffer from excessiv e and/o r irreg-
ular wear , whic h can severely impair th e brak -
ing properties and th e driving characteristics .
Ther e is a ris k of an accident.
Avoid tire pressures that are to o low in all th e
tires , includin g th e spar e wheel.

Gasoline with metalliferous additives R
Diesel
Do not mix such fuels with the fuel recom-
mended for your vehicle.
! To ensure the longevity and full perform-
ance of the engine, only premium-grade
unleaded gasoline must be used.
If standard unleaded gasoline is unavailable
and you have to refuel with unleaded gasoline
of a lower grade, observe the following pre-
cautions: R
Only fill the fuel tank to half full with regular
unleaded gasoline and fill the rest with pre-
mium-grade unleaded gasoline as soon as
possible. R
Do not drive at the maximum speed. R
Avoid sudden acceleration and engine
speeds over 3,000 rpm.
You will usually find information about the fuel
grade on the pump. If you cannot find the label
on the pump, ask the staff for assistance.
i For further information, consult a qualified
specialist workshop or visit
http://www.mbusa.com (USA only).
As a temporary measure, if the recommended
fuel is not available, you may also use regular
unleaded gasoline with an octane rating of
87 AKI/91 RON. This may reduce engine per-
formance and increase fuel consumption. Avoid
driving at full throttle and sudden acceleration.
Never refuel using fuel with a lower AKI.
Information on refueling .
Additives
! Operating the engine with fuel additives
added later can lead to engine failure. Do not
mix fuel additives with fuel. This does not
include additives for the removal and preven-
tion of residue buildup. gasoline must only be
mixed with additives recommended by
Mercedes-Benz. Comply with the instructions
for use on the product label. More information
about recommended additives can be
obtained from any authorized Mercedes-Benz
Center.
Mercedes-Benz recommends that you use bran-
ded fuels that have additives. The quality of the fuel available in some coun-
tries may not be sufficient. Residue could build
up in the injection system as a result. In such
cases, and in consultation with an authorized
Mercedes-Benz Center, the gasoline may be
mixed with the cleaning additive recommended
by Mercedes-Benz. You must observe the notes
and mixing ratios specified on the container.
Engine oil
General notes
! Never use engine oil or an oil filter of a spec-
ification other than is necessary to fulfill the
prescribed service intervals. Do not change
the engine oil or oil filter in order to achieve
longer replacement intervals than those pre-
scribed. You could otherwise cause engine
damage or damage to the exhaust gas after-
treatment.
Follow the instructions in the service interval
display regarding the oil change. Otherwise,
you may damage the engine and the exhaust
gas aftertreatment.
When handling engine oil, observe the important
safety notes on service products ( Y
page 427).
The engine oils are matched to the performance
of Mercedes-Benz engines and service intervals.
You should therefore only use engine oils and oil
filters that are approved for vehicles with main-
tenance systems.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz Center.
