Route-ahead assistant
The concept The system helps to conserve fuel and pro‐
motes a proactively driving style. It can detect
certain upcoming sections of the journey
based on the navigation data and alert the
driver to them in good time.
The detected route sections, such as built-up areas or changes of road require the driver to
reduce speed.
General information
This alert is issued even if the upcoming route
section cannot yet be detected while driving.
The alert is displayed until the route section is
reached.
If an alert is received, the vehicle's speed and
its fuel consumption can be reduced by back‐
ing off the accelerator and coasting until the
route section is reached.
Depending on the situation, the system also
uses the engine brake automatically with a
pausing of the coast, refer to page 245, func‐
tion.
Functional requirements
This function is available in ECO PRO mode.
The system depends on the timeliness and
quality of the navigation data.

System limits
The system is not available in the following sit‐
uations:
▷Speed less than 30 mph, approx. 50 km/h.▷Temporary and variable speed limit, e.g.,
for road works.▷Quality of navigation data inadequate.▷Cruise control active.
Coasting
The concept The system helps to conserve fuel.
To do this, under certain conditions the engine
is automatically decoupled from the transmis‐
sion when selector lever position D is set. The
vehicle continues traveling with the engine idling to reduce fuel consumption. Selector
lever position D remains engaged.
This driving condition is referred to as coast‐
ing.
As soon as you step on the brake or accelera‐
tor pedal, the engine is automatically coupled
again.
Information Coasting is a component of the ECO PRO, re‐
fer to page 241, driving mode.
Coasting is automatically activated when ECO
PRO mode is called via the Driving Dynamics
Control.
The function is available in a certain speed
range.
A proactively driving style helps the driver to
use the function as often as possible and sup‐
ports the fuel-conserving effect of coasting.
Safety mode
The function is not available under one of the
following conditions.▷DSC OFF or TRACTION activated.▷Driving in the dynamic limit range and on
steep uphill or downhill grades.▷Battery charge status temporarily too low
or vehicle electrical system drawing exces‐
sive current.
Functional requirements
In ECO PRO mode, this function is available in
a speed range from approximately 30 mph, ap‐
prox. 50 km/h to 100 mph, approx. 160 km/h, if
the following conditions are met:
▷Accelerator pedal and brake pedal are not
operated.▷The selector lever is in selector lever posi‐

1.Using the shift paddles + shift to the high‐
est gear.2.Shift paddles + press again to enter coast‐
ing mode.

For this purpose, the driving style is analyzed.
The assessment is done in various categories
and is displayed on the Control Display.
Using this indication, the individual driving
style can be oriented toward conserving fuel.
The current trip is assessed.
The range of the vehicle can be extended by

Wheels and tiresVehicle 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. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Tire inflation pressure Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:▷The service life of the tires.▷Road safety.▷Driving comfort.
Checking the tire inflation pressure
WARNING
A tire with low or missing tire inflation
pressure impacts handling, such as steering
and braking response. There is risk of an acci‐
dent. Regularly check the tire inflation pres‐
sure, and correct it as needed, e.g. twice a
month and before a long trip.◀
Also check the tire inflation pressure of the
emergency wheel in the trunk regularly, and
correct it as needed.
Tires have a natural, consistent loss of tire in‐
flation pressure.
Tires heat up while driving, and the tire infla‐
tion pressure increases along with the tire's
temperature. The tire inflation pressure speci‐
fications relate to cold tires or tires with the
ambient temperature.
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been parked for at least 2 hours.
The displays of inflation devices may under-
read by up to 0.1 bar, 2 psi.
For Flat Tire Monitor: after correcting the tire
inflation pressure, reinitialize the Flat Tire
Monitor.
For Tire Pressure Monitor: after correcting the
tire inflation pressure, reset the Tire Pressure
Monitor.
Tire inflation pressure specifications
The tire inflation pressure table, refer to
page 255, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. The tire inflation pres‐
sure values apply to tire sizes approved by the
manufacturer of the vehicle for the vehicle
type.
To identify the correct tire inflation pressure,
please note the following:▷Tire sizes of your vehicle.▷Maximum permitted driving speed.
Tire inflation pressures up to
100 mph/160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure
values in the tire inflation pressure table, refer
to page 255, and adjust as necessary.

Wheel and tire combination
You can ask the dealer’s service center or an‐
other qualified service center or repair shop
about the right wheel/tire combination and
wheel rim versions for the vehicle.
Incorrect wheel and tire combinations impair
the function of a variety of systems such as
ABS or DSC.
To maintain good handling and vehicle re‐
sponse, use only tires with a single tread con‐
figuration from a single manufacturer.
Following tire damage, have the original wheel
and tire combination remounted on the vehicle
as soon as possible.
WARNING
Wheels and tires which are not suitable
for your vehicle can damage parts of the vehi‐
cle, e. g. due to contact with the body due to
tolerances despite the same official size rating.
There is risk of an accident.◀
WARNING
Mounted steel wheels can cause techni‐
cal problems, e.g. independent loosening of
the lug bolts, damage to the brake discs. There
is risk of an accident. Do not mount steel
wheels.◀
Recommended tire brands
For each tire size, the manufacturer of your ve‐
hicle recommends certain tire brands. These
can be identified by a star on the tire sidewall.
New 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.
Retreaded tires
The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
WARNING
Retreated tires can have different tire
casing structures. With advanced age the serv‐
ice life can be limited. There is risk of an acci‐
dent. Do not use retreated tires.◀
Winter tires
Winter tires are recommended for operating on
winter roads.
Although so-called all-season M+S tires pro‐
vide better winter traction than summer tires,
they do not provide the same level of perform‐
ance as winter tires.
Maximum speed of winter tires If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then a respective symbol is displayed in your
field of vision. The plate is available from a
dealer’s service center or another qualified
service center or repair shop.
With mounted winter tires, observe and adhere
to the permissible maximum speed.
Run-flat tires If you are already using run-flat tires, for your
own safety you should replace them only with
the same kind. No spare tire is available in the
case of a flat tire. A dealer’s service center or
another qualified service center or repair shop
will be glad to answer additional questions at
any time.Seite 259Wheels and tiresMobility259

The system must have been reset with the
correct tire inflation pressure; otherwise, relia‐
