Microfilter/activated-charcoal filter
In external and recirculated air mode the mi‐
crofilter/activated charcoal filter filters dust,
pollen, and gaseous pollutants out of the air.
This filter should be replaced during scheduled
maintenance, refer to page 188, of your vehi‐
cle.

Parked-car ventilation
The concept The parked-car ventilation ventilates the vehi‐
cle interior and lowers its temperature, if
needed.
The system can be switched on and off at any
external temperature, either directly or by us‐
ing two preset reel-on times. It remains
switched on for 30 minutes.
Open the vents to allow air to flow out.

The system will only be switched on within the
next 24 hours. After that, it needs to be reacti‐
vated.

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.
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.
Manual transmission:
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if needed.
M double-clutch transmission:
You can increase the engine's braking effect
by shifting down in sequential mode, refer to
page 71.
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.
Ground clearance Limited ground clearance
Observe the limited ground clearance of
the vehicle, e. g. while entering underground
parking garages or when driving over obsta‐
cles. Otherwise, damages to the vehicle may
result.◀

Tires with DOT codes meet the guidelines of
the U.S. Department of Transportation.
Tire age DOT … 0115: the tire was manufactured in the
1st week of 2015.
Recommendation
Regardless of wear and tear, replace tires at
least every 6 years.
Uniform Tire Quality Grading Quality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section width.
For example: Treadwear 200; Traction AA;
Temperature ADOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to Fed‐
eral Safety Requirements in addition to these
grades.
Treadwear The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov‐
ernment test course. For example, a tire
graded 150 would wear one and one-half, 1 g,
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and may depart signifi‐
cantly from the norm due to variations in driv‐
ing habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to lowest,
are AA, A, B, and C.
Those grades represent the tire's ability to
stop on wet pavement as measured under
controlled conditions on specified government
test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction tests,
and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
Temperature The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the ma‐
terial of the tire to degenerate and reduce tire
life, and excessive temperature can lead toSeite 174MobilityWheels and tires174
