@ Tips
-After starting a cold engine, there may
be a brief period of increased noise be
cause the o il pressure m ust first build up
i n the hydraulic valve adjusters. T his is
norma l and not a cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignition will switch off
after a certain period of time. Please
note that electr ical equipment such as
exter ior lights wi ll switch off as well
when that happens.
Switching engine off
A ppl ies to vehicles: with Convenie nce key
.,. Bring your vehicle to a complete stop.
.,. Move the selector lever to the P or N posi
tion.
.,. Press the
!START ENGINE STOPI button
c> page 86, fig. 99.
St eering lock
The stee ring locks when you turn the engine
off using the
I START ENGINE STOP I button
and open the driver's door . The locked steer
ing helps prevent vehicle theft.
Emergency off
If necessary, the eng ine can be sw itched off
with the selector leve r in the R or D/S posi
tions . To do so, step on the brake peda l and
press and hold the
I START ENGINE STOP I but
ton. The vehicle speed must be less than 6 mph/ 10 km/h.
A WARNING
- Never turn off the eng ine before the ve
hicle has come to a complete stop. The
full function of the brake booste r and the
powe r steering is not guara nteed. You
must use mo re fo rce to turn or b rake if
necessary. Because yo u cannot steer and
brake as you usua lly would, this could
lead to c rashes and serious injur ies.
- F or safety reasons, you should always
par k your vehicle with the se lector lever
On th e ro ad 87
in P. Otherwise, the vehicle could inad
vertently roll away.
- The radiator fan can continue to run for
up to 10 minutes even after you have
turned off the engine and removed the
ignit ion key. The radiator fan can a lso
turn on again if the engine coo lant heats
up because of intense sunlight or heat
bui ld-up in the engine compa rtment.
- Always take the key w ith you whenever
you leave your veh icle . Otherwise, the
eng ine could be sta rted or elect rical
equ ipme nt such as the power windows
co uld be ope rated. This can lead to seri
ous injury.
- Never leave children or persons req uiring
assistance unattended in the vehi cle. The
doors can be locked using the remote
transmitter, preventing people from es
caping from the veh icle on their own in
the event of an emergency. Depending
on the time of year, peop le inside the ve
hicle can be exposed to very high or very
low tempe ratu res.
(D Note
If the engine has been under heavy load
for an extended period, heat bu ilds up in
the e ng ine compartment after the engine
i s sw itched off - there is a r isk of damag ing
the e ngine. A llow the engi ne to run at id le
for abo ut two minute s before switching it
off.

Start-Stop-System
Descript ion
A ppl ies to vehicles: with Sta rt-Stop-System
The Start-Stop -System can help increase fuel
economy and reduce CO
2 emissions.
In the Start-Stop-mode, the eng ine shuts off
automatically when the vehicle is stopped,
such as at a traffic light. The ignition remains
sw itched on during this stop phase. The en
gine will be automatically restarted when
needed.
The last Start-Stop-System setting (o n/off us
ing the button
lr.;, .. I) will be restored when the
ignition is turned on. The LED in the
1r.;, .. 1 but
ton turns on when the Start-Stop-System is
switched off manually.
Basic requirements for the Start-Stop
mode
- The driver's door is closed .
- The driver's seat belt is latched.
- The hood is closed.
- The vehicle must have been driven faster
than 2.5 mph (4 km/h) since the last stop .
- A tra iler is not hitched to the veh icle .
A WARNING
- Never turn off the engine before the ve
hicle has come to a complete stop. The
full function of the brake booster and the
power steering is not guaranteed. You
On the road 91
must use more force to turn or brake if
necessary. Because you cannot steer and
brake as you usually would, this could
lead to crashes and ser ious injuries.
- To reduce the risk of injuries, make sure
that the Start-Stop-System is turned off
when working in the engine compart
ment

Always switch off the Start-Stop-System
when driving through water

Additional information
T he engine will switch off in the P, D/S and N
positions as well as in ma nual mode. In the P
position, the engine will also remain off if you
take your foot off the brake pedal. The engine
starts again when you select another selector lever position and take your foot off the brake
pedal.
If you se lect the R position during a Stop
phase, the engine will start again .
92 On the road
Shift from D/S to P quickly to prevent the en
gin e from starting unintentionally when shift
ing through R.
You can dete rm ine fo r yoursel f if the eng ine
will stop or not by reducing o r increasing the
amo unt of force you use to press th e brake
pedal. For example, if you only lightly press
on the brake pedal in stop-and and -go traffic
o r when turning , the engine will not switch off
when the vehicle is stationary . As soon as you
press the brake down harder , the eng ine will
switch off.

- Switch the cruise control off temporarily
when dr iv ing in turning lanes, h ighway

- Please note that unconsciously "resting" your foot on the accelerator pedal causes cru ise contro l not to brake. This is due to
the control system be ing overridden by
the driver's acceleration.
- Never use the cruise control when driving off-road or on unpaved roads. The c ruise

Start-Stop function
The combustion engine is operated on ly as
needed. Generally, the combustion engine
turns off when the vehicle is stationary and
the high voltage battery powers the electrical
vehicle systems.
The purpose of automatica lly shutting the
combustion engine off in hybrid drive mode is
to save fuel. All of the important veh icle sys
tems, such as steering, brakes and the A/C
system, cont inue to remain active. In some
cases, systems may require the combustion
engine to cont inue running when the vehicle
is stationary. When dr iv ing in congested traf
fic for long per iods of time, the combustion
engine w ill cycle on when the vehicle is sta
tionary to keep the high voltage battery
charged.
Gliding
I f the gas pedal is not pressed and the D posi
tion is selected, the combustion engine re-
Hybrid 101
mains turned off up to speeds of approxi
mately 99 mph ( 160 km/h) . Driving conserva
tive ly like this can reduce fuel consumption .
Energy recovery (recuperation)
When braking, the elect ric motor will act as a
generator creating e lectric energy that is then
stored in the high voltage battery. This also
occurs when the ve hicle is coasting or driving
downhi ll. The combustion engine is automati
cally turned off in this case.
The vehicle is braked with the electric motor
by applying ear ly and even pressure to the
brakes and using short pedal movements
¢ page 98, fig. 107 @. By doing this, a large
amount of the kinetic energy is recovered and may be stored as electric energy in the high
voltage battery. During heavy braking, the
convent ional brakes are also act ivated
c::> page 98, fig. 107 @.
The energy recovery is shown in the MMI dis
play
c::> page 104 .
Automatic start of the combustion engine
Various operating conditions cause the com
bust ion engine to start automat ically :
- The high voltage battery charge leve l is low.
- The temperature of the comb ustion engine
is low.
- The temperature of the catalyt ic converter is
low .
- The power output needed for the A/C sys-
t em is high.
- The vehicle speed is hig h.
- The vehicle acceleration is high.
- The inclin e is steep.
- High charge level for the high voltage bat-
tery when coasting. In th is case, the h igh
voltage battery cannot absorb any mo re en
ergy and so the electric motor cannot slow
down the veh icle. The combustion engine
tu rns on (engine brake). In this situation the
h igh voltage battery will show a Ma x charge.
