Parking assistantThe concept
This system assists the driver in parking paral‐
lel to the road.
Ultrasound sensors measure parking spaces
on both sides of the vehicle.
The parking assistant calculates the best pos‐
sible parking line and takes control of steering
during the parking procedure.
When parking, also take note of the visual and
acoustic information issued by the PDC and
the parking assistant and react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 144.
Hints Personal responsibility
The parking assistant does not relieve
the driver of responsibility for the vehicle dur‐
ing the parking procedure.
Watch the parking space and parking proce‐
dure closely and intervene if necessary; other‐
wise, there is the danger of an accident.◀
Changes to the parking space
Changes to the parking space after it was
measured are not taken into account by the
system.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the danger of an acci‐
dent occurring.◀
Transporting loads
Loads that extend beyond the perimeter
of the vehicle are not taken into account by the
system during the parking procedure.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the danger of an acci‐
dent occurring.◀
Curbs
The parking assistant may steer the vehi‐
cle over or onto curbs.
Therefore, always be alert and ready to inter‐
vene; otherwise, the wheels, tires, or the vehi‐
cle may become damaged.◀

Things to remember when drivingVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Breaking-in period General information Moving parts need to be broken in to adjust to
each other.
The following instructions will help achieve a
long vehicle life and good economy.
Engine and differential Always obey the official speed limit.
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road
speed:▷For gasoline engine 4,500 rpm and
100 mph/160 km/h.
Avoid full load or kickdown under all circum‐
stances.
From 1,200 miles/2,000 km The engine and vehicle speed can gradually be
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full
traction potential until after an initial breaking-
in period.
Drive conservatively for the first
200 miles/300 km.
Brake system
Brakes require an initial break-in period of ap‐
prox. 300 miles/500 km to achieve optimized
contact and wear patterns between brake
discs and brake pads. Drive moderately during
this break-in period.
Following part replacement
The same breaking in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
Using the hybrid systemefficiently
The concept Your vehicle's hybrid system runs automati‐
cally. Through foresighted driving, the hybrid
properties are efficiently used, i.e., fuel con‐
sumption and energy recovery are optimized.
Optimizing energy recovery
Types of energy recovery Energy recovery is used to charge the high-
voltage battery. It is important for the supply of
electrical components and thus a prerequisite
for fuel economy. It appears in three stages
during coasting to a halt and braking:
Low energy recovery:
Seite 180Driving tipsThings to remember when driving180
Online Edition for Part no. 01 40 2 909 774 - VI/13
When coasting to a halt without pressing the
brake pedal.
Average energy recovery:
During a slight deceleration by gently pressing
the brake pedal.
Maximum energy recovery:
By pressing the brake pedal harder.
Brake according to the situation
Brake in accordance with the traffic con‐
ditions, or there is the risk of accident.◀
Optimum energy recovery
As soon as the display shows the maximum
energy recovery, only press the brake pedal
harder if required by the situation.
Driving situation examples for fuel
economy
In many driving situations, the hybrid system
allows for a particularly efficient energy man‐
agement.
▷Stop-and-go traffic:The combustion engine is switched on or
over automatically by the hybrid system.▷Driving with constant speed:
With the ASSIST acceleration support, the
electric motor relieves the combustion en‐
gine periodically by being switched on au‐
tomatically.
Discharge of the high-voltage battery
In normal operation, a sufficient charging of the
high-voltage battery is ensured by energy re‐
covery. Longer idle periods can reduce the
charge state of the high-voltage battery.
Do not allow the vehicle to sit idle for ex‐
tended periods with a low charging state
Before storing the vehicle for an extended pe‐
riod, check the battery charge indicator to en‐
sure that the high-voltage battery is fully
charged. If necessary, charge the high-voltage
battery by driving the vehicle. Check the
charge level regularly, and if necessary re‐
charge the high-voltage battery by driving the
vehicle. Allowing the high-voltage battery
charge to drop too low will damage the bat‐
tery.◀
Charging by driving
In order to charge the high-voltage battery
most effectively when driving, activated the
transmission's Sport program DS, refer to
page 83.
Coasting to a standstill and braking phases are
used more often to recover energy.
eDRIVE electric driving and the Auto Start
Stop function will also be deactivated.

Fast chargingIn exceptional cases it can be charged in place,
such as before extended idle phases in order
to prevent damage to the high-voltage battery.1.Start the engine.2.Engage transmission position P and set
parking brake.3.Press and hold down brake pedal.4.Use the accelerator pedal to maintain an
engine speed of approx. 2,000 rpm.
After a few minutes, the high-voltage battery is
fully charged again.
The battery charge indicator in the instrument
cluster, refer to page 97, is used to check the
status.
General driving notes
Closing the trunk lid Drive with the trunk lid closed
Only drive with the tailgate closed; other‐
wise, in the event of an accident or braking and
evasive maneuvers, passengers and other road
users may be injured, and the vehicle may be
damaged. In addition, exhaust fumes may en‐
ter the passenger compartment.◀
If driving with the tailgate open cannot be
avoided:
▷Close all windows and the glass sunroof.▷Greatly increase the blower speed.▷Drive moderately.
Hot exhaust system
Hot exhaust system
High temperatures are generated in the
exhaust system.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that flammable materials, e. g. hay, leaves,
grass, etc. do not come in contact with the hot
exhaust system during driving, while in idle po‐
sition mode, or when parked. Such contact
could lead to a fire, and with it the risk of seri‐
ous personal injury as well as property dam‐
age.
Do not touch hot exhaust pipes; otherwise,
there is the danger of getting burned.◀
Climate control windshield
The marked area is not covered with heat re‐
flective coating.
Use this area for garage door openers, devices
for electronic toll collection, etc.
Climate control laminated tinted
safety glass
The vehicle glass provides full protection
against the harmful effects of UV radiation on
the skin.
Mobile communication devices in thevehicle
Mobile communication devices in the ve‐
hicle
It is advised that you do not use mobile com‐
munication devices, e.g., mobile phones, in‐
side the vehicle without connecting them di‐
rectly to the external antenna. Otherwise, the
vehicle electronics and mobile communication
devices can interfere with each other. In addi‐
tion, there is no assurance that the radiation
generated during transmission will be dis‐
charged from the vehicle interior.◀

Hydroplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.
Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent hydroplaning.◀
Driving through water Drive though calm water only and only if it is
not deeper than. 9.8 inches/25 cm and at this
height, no faster than walking speed, up to 6 mph/10 km/h.
Adhere to water depth and speed limita‐
tions
Do not exceed this water depth and walking
speed; otherwise, the vehicle's engine, the
electrical systems and the transmission may
be damaged.◀
Braking safely
Your vehicle is equipped with ABS as a stand‐
ard feature.
Applying the brakes fully is the most effective
way of braking in situations when this is neces‐
sary.
The vehicle maintains steering responsive‐
ness. You can still avoid any obstacles with a
minimum of steering effort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.Objects in the area around the pedals
No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved
for the vehicle and can be properly fixed in
place.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, for example.◀
Driving in wet conditions When roads are wet coated with road salt or
there is heavy rain, briefly exert gentle pres‐
sure on the brake pedal every few miles.
Ensure that this action does not endanger
other road users.
The heat generated in this process helps dry
the brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills
Drive long or steep downhill gradients in the
gear in which the least braking is required.
Otherwise, the brake system may overheat, re‐
sulting in a reduction in the brake system effi‐ ciency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if necessary.
Avoid load on the brakes
Avoid placing excessive load on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brake wear
and possibly even brake failure.◀Seite 183Things to remember when drivingDriving tips183
Online Edition for Part no. 01 40 2 909 774 - VI/13
Do not drive in neutral
Do not drive in neutral or with the engine
stopped, as doing so disables engine braking.
In addition, steering and brake assist is un‐
available with the engine stopped.◀
Brake disc corrosion The corrosion on the brake discs and the con‐
tamination on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops that exits under‐
neath the vehicle.
Traces of water under the vehicle like this are
normal.
