Saving fuelVehicle features and optionsThis 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.
General information Your vehicle contains advanced technology for
the reduction of fuel consumption and emis‐
sions.
Fuel consumption depends on a number of dif‐
ferent factors.
Carrying out certain measures, such as a mod‐
erate driving style and regular maintenance,
can influence fuel consumption and the envi‐
ronmental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts
following use
Remove auxiliary mirrors, roof or rear luggage
racks which are no longer required following use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.Close the windows and glass
sunroof
Driving with the glass sunroof and windows
open results in increased air resistance and
thereby reduces the range.
Tires
General information Tires can affect fuel consumption in various
ways, e.g., tire size may influence fuel con‐
sumption.
Check the tire inflation pressure
regularly
Check and, if needed, correct the tire inflation
pressure at least twice a month and before
starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away immediately
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate engine speeds.
This is the quickest way of warming the cold
engine up to operating temperature.
Look well ahead when
driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐
cle driving ahead of you.
Driving smoothly and proactively reduces fuel
consumption.Seite 158Driving tipsSaving fuel158

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
Check the tire inflation pressure regularly
Regularly check the tire inflation pres‐
sure, and correct it as needed: at least twice a
month and before a long trip. If you fail to ob‐
serve this precaution, you may be driving on
tires with incorrect tire pressures, a condition
that may not only compromise your vehicle's
driving stability, but also lead to tire damage
and the risk of an accident.◀
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 1.45 psi/0.1 bar.
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 173, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. Tire inflation pressure
specifications apply to approved tire sizes and
recommended tire brands. This information
can be obtained from your service center.
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 173, and adjust as necessary.

Approved wheels and tires
You should only use wheels and tires
that have been approved by the vehicle manu‐
facturer for your vehicle type; otherwise, e.g.,
despite having the same official size ratings,
variations can lead to chassis contact and with
it, the risk of severe accidents
The manufacturer of your vehicle cannot eval‐
uate non-approved wheels and tires to deter‐
mine if they are suited for use, and therefore
cannot guarantee the operating safety of the
vehicle.◀
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.
With proper use, these tires meet the highest
standards for safety and handling.
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.
Retreaded tires
Possibly substantial variations in the de‐
sign and age of the tire casing structures can
limit service life and have a negative impact on
road safety.◀
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. You can obtain this sign from the
tire specialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for
the respective winter tires; otherwise, tire dam‐
age and accidents can occur.◀
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. Your service center will be
glad to advise you.
Rotating wheels between axlesDifferent wear patterns can occur on the frontand rear axles depending on individual driving
conditions. The tires can be rotated between
the axles to achieve even wear. Your service
center will be glad to advise you. After rotating,
check the tire pressure and correct if needed.
Rotating the tires is not permissible on vehi‐
cles with different tire sizes or rim sizes on the
front and rear axles.Seite 179Wheels and tiresMobility179
Online Edition for Part no. 01 40 2 961 270 - II/15

StorageStore wheels and tires in a cool, dry place with
as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.
Run-flat tires Label
RSC label on the tire sidewall.
The wheels consist of tires that are self-sup‐
porting, to a limited degree, and possibly spe‐
cial rims.
The support of the sidewall allows the tire to
remain drivable to a restricted degree in the
event of a tire inflation pressure loss.
Follow the instructions for continued driving
with a flat tire.
Changing run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire.
Your service center will be glad to advise you.
Mobility System
The concept With the Mobility System, minor tire damagecan be sealed quickly to enable continued
travel. To accomplish this, sealant is pumped
into the tires, which seals the damage from the inside.
The compressor can be used to check the tire inflation pressure.
Hints▷Follow the instructions on using the Mobi‐
lity System found on the compressor and
sealant container.▷Use of the Mobility System may be ineffec‐
tive if the tire puncture measures approx.
1/8 in/4 mm or more.▷Contact the nearest service center if the
tire cannot be made drivable.▷If possible, do not remove foreign bodies
that have penetrated the tire.▷Pull the speed limit sticker off the sealant
container and apply it to the steering
wheel.▷The use of a sealant can damage the TPM
wheel electronics. In this case, have the
electronics checked at the next opportu‐
nity and have them replaced if needed.
Enclosed areas
Do not let the engine run in enclosed
areas, since breathing in exhaust fumes may
lead to loss of consciousness and death. The
exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀
Storage The Mobility System is located under the
cargo floor panel.

running, reel on the compressor.
Switch off the compressor after 10 mi‐
nutes
Do not allow the compressor to run longer than
10 minutes; otherwise, the device will overheat
and may be damaged.◀
Let the compressor run for approx. 3 to 8 mi‐
nutes to fill the tire with sealant and achieve a
tire inflation pressure of approx. 2.5 bar.
While the tire is being filled with sealant, the
tire inflation pressure may sporadically reach
approx. 5 bar. Do not reel off the compressor at
this point.
If a tire inflation pressure of 2 bar is not
reached:
1.Switch off the compressor.2.Unscrew the filling hose from the wheel.3.Drive 33 ft/10 m forward and back to dis‐
tribute the sealant in the tire.4.Inflate the tire again using the compressor.
If a tire inflation pressure of 2 bar cannot be
reached, contact your service center.
