Safety beltsSeats with safety belt
The vehicle has four seats, each of which is
equipped with a safety belt.
Number of safety belts
Your vehicle has been fitted with four safety
belts for your and your passengers' safety.
However, they can only offer protection when
adjusted correctly.
General information Always make sure that safety belts are being
worn by all occupants before driving off.
For the occupants' safety the belt locking
mechanism triggers early. Slowly guide the
belt out of the holder when applying it.
Although airbags enhance safety by providing
added protection, they are not a substitute for
safety belts.
The upper shoulder strap's anchorage point
will be correct for adult seat occupants of ev‐
ery build if the seat is correctly adjusted.
Hints One person per safety belt
Never allow more than one person to
wear a single safety belt. Never allow infants or
small children to ride on a passenger's lap.◀
Putting on the belt
Lay the belt, without twisting, snugly
across the lap and shoulders, as close to the
body as possible. Make sure that the belt lies
low around the hips in the lap area and does
not press on the abdomen. Otherwise, the belt
can slip over the hips in a frontal impact and in‐
jure the abdomen.
The safety belt must not lie across the neck, rub on sharp edges, be routed over breakable
objects, or be pinched.◀What reduces the restraining effect
Avoid wearing bulky clothing, and pull
the shoulder belt periodically to readjust the
tension. Make sure that the belt is not jammed;
otherwise, the belt can be damaged and the
restraining effect is reduced.◀

Driving with the combustion
engine: POWER
Depending on the operating state, the com‐
bustion engine is automatically switched on:
▷Selector lever position Sport is set.▷Speed for electric driving is exceeded.▷The high-voltage battery has an insuffi‐
cient charge.▷High-voltage battery is completely
charged, e.g., when driving downhill.▷For improved traction, e.g., on slippery
roads.▷During intense accelerations or on inclines.▷System-related requirement for hybrid
components.▷Adapting to the course of the road when
destination guidance is activated.
When reducing speed, the combustion engine
is switched off when the conditions for electric
driving, refer to page 61, are met.
Assistance for the
combustion engine
Depending on the operating state, the electric
motor provides assistance with additional pro‐
pulsive power.
ASSIST
During normal vehicle operation, the electric
motor assists the combustion engine, depend‐
ing on the situation.
eBOOST Accelerating quickly, such as when passing,
requires the maximum available power from
the electric motor. To do this, apply extra force
to the accelerator pedal.
Energy recovery: CHARGE
The high-voltage battery is recharged in part
through energy recovery. The electric motor
acts as a generator when decelerating and
converts the kinetic energy into electrical en‐
ergy.
Energy can be recovered if the following condi‐
tions are met:
▷The vehicle is moving.Seite 62ControlsDriving62
Online Edition for Part no. 01 40 2 957 072 - X/14
▷Speed higher than approx.
12 mph/20 km/h.▷Selector lever in selector lever position D,
R or S.▷The high-voltage battery is not fully
charged.▷Accelerator pedal is not operated.
Energy cannot be recovered in the following
situations:
▷Selector lever position N is set.▷While drive stability control systems con‐
trol the vehicle, even though it is not indi‐
cated by an indicator light.▷The high-voltage battery is fully charged.▷When temperature of the high-voltage bat‐
tery is very low or very high.
With cold external temperatures, it is pos‐
sible that the energy recovery is tempora‐
rily unavailable after startup.
