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.

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.

126 Automatic transmission
8_ WARNING
-Unintended vehicle movement can cause
serious injury .
- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running,
activate the parking brake and move the
selector lever to P.
- Power is still transmitted to the wheels
when the engine is running at idle. To
prevent the vehicle from "creeping", you
must keep your foot on the brake when
the engine is running and the selector lever is in D/S or R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the selector lever position
while the vehicle is stationary and the
engine is running.
- Never shift into
R or P while driving.
- Before driving down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases
braking distance or causes complete fail­
ure of the brake system .
- To preven t the vehicle from rolling back
when stopping on inclines, always hold it
in place with the brake pedal or parking
brake.
- Never hold the vehicle on an incline with
a slipping clutch . The clutch opens auto­
matically when it becomes too hot from
the overload. An indicator lamp
[O] illu­
minates and a driver message appears
<=:> page 128when the clutch is overload­
ed.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake set
r:::> page 231 . Otherwise, any increase in engine speed may set the vehicle in mo­
tion, even with the parking brake ap­
plied.
(D Note
- When stopping on an incline , do not try
to hold the vehicle in place by pressing
the accelerator pedal while a driving gear is selected. This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the parking brake or press the brake pedal to prevent the vehicle from rolling .
- Allowing the vehicle to roll when the en ­
gine is stopped and the selector lever is
in N will damage the transmission be­
cause it is not lubricated under those cir­
cumstances.
@ Tips
For safety reasons, the parking brake is re­
leased automatically only when the driv­
er's safety belt is engaged in the buckle.
Hill descent control
The hill descent control system assists the
driver when driving down declines.
Hill descent control is activated when these­
lector lever is in D /S and you press the brake
pedal. The transmission automatically selects
a gear that is suitable for the incline. Hill de­
scent control tries to maintain the speed ach­
ieved at the time of braking, within physical
and technical limitations. It may still be nec­
essary to adjust the speed with the brakes .
Hill descent control switches off once the de­
cline levels out or you press the accelerator
pedal.
When the speed is set in the cruise control
system
r:::> page 95, hill descent control is also
activated.
A WARNING
-
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all

Homelink
Universal remote
control
Description
Applies to vehicles: with Home link
The HomeLink universal remote control can
be programmed with the remote control for
devices that are already present.
With Home Link, you can control devices such
as the garage door, security systems, house
lights , etc. comfortably from the inside of you
vehicle.
Homelink makes it possible for you to rep lace
three different remote controls from dev ices
in your home with one universal remote. This
feature works for most garage door and exte­
rior door motor signals. Programming the in­
dividual remote control for your remote con ­
trol takes place near the center of the radiator
grille. There is a control module attached at
this location .
A one-time programming of the sensor must be performed before you are able to use sys­
tems with Homelink. If the system does not activate after performing the one-time pro­
gramming, check whether the system uses a rolling code¢
page 138 for vehicles without
the MMI*.
& WARNING
-
- Never use the Homelink transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as requ ired by federa l safety stand­
ards. This includes any garage door open­
er model manufactured before April 1,
1982.
-A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards . Using a garage door
opener without these features increases
risk of serious injury or death.
Homelink 135
- For safety reasons never release the
parking brake or start the engine while
anyone is standing in front of the vehicle .
- A garage door or an estate gate may
sometimes be set in motion when the
Homelink remote control is being pro­
grammed. If the device is repeatedly ac­
tivated, th is can overstrain motor and
damage its electrical components - an
overheated mo to r i s a fire hazard!
- To avoid possib le injuries or property
damage, please always make abso lutely
certa in that no persons or objects are lo­
cated in the range of motion of any
equipment being operated.

unfolds with great force in the blink of
an eye .
- Always make sure that there are at least
10 inches (25 cm) between the front
passenger's breastbone and the instru­
ment panel.
- Each passenger must always sit on a seat of their own and properly fasten and
wear the safety belt belonging to that
seat.
- Before driving, always adjust the front
passenger seat and head restraint prop­
erly .
- Always keep your feet on the floor in
front of the seat. Never rest them on the
seat, instrument panel, out of the win­
dow, etc. The airbag system and safety
belt will not be able to protect you prop­
erly and can even increase the risk of in­
jury in a crash.
- Never drive with the backrest reclined or
tilted far back! The farther the backrests
are tilted back, the greater the risk of in­
jury due to incorrect positioning of the
safety belt and improper seating posi­
tion.
- Children must always ride in child safety
seats
c::> page 178. Special precautions
apply when installing a child safety seat
on the front passenger seat
c::> page 15 7 .
Proper seating positions for passengers
in rear seats
Rear seat passengers must sit upright with
both feet on the floor consistent with their
physical size and be properly restrained whenever the vehicle is in use .
To reduce the risk of injury caused by an incor­
rect seating position in the event of a sudden
braking maneuver or an accident, your pas­
sengers on the rear bench seat must always
observe the following :
.. If there is a passenger on the rear center
seating pos ition, slide the center head re­
straint upward at least to the next notch
c::> page 65.
.. Make sure that the seatback is securely
latched in the upright position
c::> page 67.
.. Keep both feet flat in the footwell in front of
the rear seat .
.. Fasten and wear safety belts properly
c::>page 152.
.. Make sure that children are always properly
restrained in a child restraint that is appro­
priate for their size and age
c::> page 178.
_& WARNING
Passengers who are improperly seated on
the rear seat can be seriously injured in a
crash .
- Each passenger must always sit on a seat
of their own and properly fasten and
wear the safety belt belonging to that seat .
- Safety belts only
offer maximum protec­
tion when the seatback is securely latch­
ed in the upright position and the safety
belts are properly positioned on the
body. By not sitting upright, a rear seat
passenger increases the risk of personal
injury from improperly positioned safety
belts!
- Always adjust the head restraint properly
so that it can give maximum protection.
Proper adjustment of head restraints
-
Correctly adjusted head restraints are an im­
portant part of your vehicle's occupant re ­
straint system and can help to reduce the risk
of injuries in accident situations.
