Performance Control Performance Control enhances the agility of
the vehicle.
To increase maneuverability, with a corre‐
spondingly sporty driving style, wheels are
braked individually. The resulting braking
power is simultaneously largely compensated
by an engine intervention.
Due to the variable drive configuration, this in‐
tervention can be done either on the front axle,
the rear axle or on both axles simultaneously.
Driving Dynamics Control The conceptThe Driving Dynamics Control helps to fine-
tune the vehicle's settings and features. Vari‐
ous programs can be selected for this purpose.
Note
Pressing the Driving Dynamics Control deacti‐
vates the Sport program, refer to page 69, of

This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems.
Cruise controlThe concept
The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Hints Unfavorable conditions
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, e.g.:▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
Otherwise, you could lose control of the vehi‐
cle and cause an accident.◀

Things to remember when drivingVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems.
Breaking-in period
General information Moving parts need time to adjust to one an‐
other (break-in time).
The following instructions will help accomplish
a long vehicle life and good efficiency.
During break-in, do not use the Launch Con‐
trol, refer to page 70.
Engine, transmission, and axle drive 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
Tire traction is not optimal due to manufactur‐
ing circumstances when tires are brand-new;
they achieve their full traction potential after a
break-in time.
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 optimal per‐
formance between brake discs and brake
pads. Drive moderately during this break-in pe‐
riod.
Following part replacement
The same break-in procedures should be ob‐
served if any of the components above-men‐
tioned have to be renewed in the course of the
vehicle's operating life.
Using eDRIVE efficiently The concept
eDRIVE operates automatically. Proactive driv‐
ing utilizes energy consumption and energy re‐
covery optimally. Energy recovery is used to
charge the high-voltage battery. It is important
for the supply of electrical components and
thus a prerequisite for an extensive range. En‐
ergy consumption and recovery depend very
much, among other things, on your driving
style.
Optimizing driving style
Performance display The driving style can be optimized using the
performance display in ECO PRO mode.Seite 134Driving tipsThings to remember when driving134
Online Edition for Part no. 01 40 2 957 072 - X/14

The driving style is efficient as long as the ac‐
celerator pedal pointer is within the lower
range highlighted in blue during acceleration
and deceleration.
The energy recovery occurs during coasting
and braking and is displayed in the perform‐
ance display by the accelerator pedal indicator.
The accelerator pedal pointer is within the
CHARGE range.
Efficient energy recovery:
▷The accelerator pedal moves to the left
within the blue range of the CHARGE dis‐
play, arrow 1.▷The energy use while driving can be opti‐
mized by efficient acceleration.
Efficient acceleration:
▷The accelerator pedal moves to the right
within the blue range of the eDRIVE dis‐
play, arrow 2.▷Use deceleration during coasting as often
as possible for energy recovery.
Brake according to traffic and circum‐
stances
Brake in accordance with the traffic conditions,
or there is the risk of accident.◀
Using drive modes and assistance
systems
Max eDRIVE
Max eDRIVE, refer to page 61, forces electric
driving. Electric driving is especially efficient
for short distances, low to medium speeds and
in stop-and-go traffic.
SAVE battery
SAVE Battery, refer to page 61, conserves the
electric range for a later point in time. In this
case, the vehicle is driven primarily by the
combustion engine.
ECO PRO ECO PRO, refer to page 141, supports a driv‐
ing style that saves on fuel consumption. For
this purpose, the engine control and comfort
features, e. g. the climate control output, are
adjusted.
Discharge of the high-voltage battery 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. During the idle period, connect the
vehicle to a charging station at a suitable
charging location. If necessary, the high-volt‐
age battery will be charged automatically.
Make sure that the charging process takes
place. Regularly check the charging state.
Don't allow battery charge status to drop too
low - it will damage the battery.◀
General driving notes
Closing the tailgate Drive with the tailgate closed
Only drive with the tailgate closed; other‐
wise, in the event of an accident or braking and
evasive maneuvers, passengers and other traf‐
fic may be injured, and the vehicle may be
damaged.◀Seite 135Things to remember when drivingDriving tips135
Online Edition for Part no. 01 40 2 957 072 - X/14

If driving with the tailgate open cannot be
avoided:▷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 while driving, while in idle po‐
sition mode, or when parked. Such contact
could lead to a fire, resulting in an increased
risk of serious personal injury as well as prop‐
erty damage.
Do not touch hot exhaust pipes; otherwise,
there is a danger of getting burned.◀
Mobile communication devices in the
vehicle
Mobile communication devices in the ve‐
hicle
It is not recommended to use mobile phones,
such as mobile phones, in the vehicle interior
without a direct connection to an external aer‐
ial. Otherwise, the vehicle's electronics and
mobile communication devices can interfere
with each other. In addition, there is no assur‐
ance that the radiation generated during trans‐
mission will be conducted away from the vehi‐
cle interior.◀
Hydroplaning Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent 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.
Driving through water Observe water level and speed
Do not exceed the maximum water level
and maximum speed; otherwise, the vehicle's
engine, the electrical systems and the trans‐
mission may be damaged.◀
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
3 mph/5 km/h.
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 needed.
Steering is still responsive. You can still avoid
any obstacles with a minimum of steering ef‐
fort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
In certain braking situations, the perforated
brake discs can cause functional problems.
However, this has no effect on the perform‐
ance and operational reliability of the brake.
Objects within the range of movement
of the pedals
No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the pedal area; otherwise, the
function of the pedals could be impeded while driving and create the risk of an accident.
Do not place additional floor mats over existing
mats or other objects.Seite 136Driving tipsThings to remember when driving136
Online Edition for Part no. 01 40 2 957 072 - X/14

Only use floor mats that have been approved
for the vehicle and can be properly attached to
floor.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, e.g.◀
Driving in wet conditions When roads are wet, salted, or in heavy rain,
press brake pedal ever so gently every few
miles.
Ensure that this action does not endanger other traffic.
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 Avoid stressing the brakes
Avoid placing excessive stress on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brakes
wearing out and possibly even brake failure.◀
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 are un‐
available with the engine stopped.◀
Drive long or steep downhill gradients in the
gear that requires least braking efforts. Other‐
wise the brakes may overheat and reduce
brake efficiency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if needed.
On downhill sections, use energy recovery if
possible to decelerate the vehicle.
Brake disc corrosion
Brake disc corrosion and contamination of the
brake pads are favored by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion will built up when the maximum
pressure applied to the brake pads during
braking is not reached - thus discs don't get
cleaned.
Corrosion buildup on the brake discs will cause
a pulsating effect on the brakes in their re‐
sponse - generally that cannot be corrected.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops collecting under‐
neath the vehicle.
These traces of water under the vehicle are
normal.
