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. A dealer’s
service center or another qualified service cen‐
ter or repair shop will be glad to answer addi‐
tional questions at any time. 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.
Storage
Store 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. A
dealer’s service center or another qualified
service center or repair shop will be glad to an‐
swer additional questions at any time.
Repairing a flat tire Safety measures▷Park the vehicle as far away as possible
from passing traffic and on solid ground.▷Switch on the hazard warning system.▷Secure the vehicle against rolling away by
setting the parking brake.▷Turn the steering wheel until the front
wheels are in the straight-ahead position
and engage the steering wheel lock.▷Have all vehicle occupants get out of the
vehicle and ensure that they remain out‐
side the immediate area in a safe place,
such as behind a guardrail.▷If necessary, set up a warning triangle at an
appropriate distance.
Mobility System
The concept
With the Mobility System, minor tire damage
can 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.
Information
▷Follow the instructions on using the Mobi‐
lity System found on the compressor and
sealant container.Seite 260MobilityWheels and tires260

Take care not to add too much engine oil.CAUTION
Too much engine oil can damage the en‐
gine or the catalytic converter. There is risk of
property damage. Do not add too much engine
oil. Have too much engine oil siphoned off by a
dealer’s service center or another qualified
service center or repair shop.◀
Detailed measurement
The concept In the detailed measurement the engine oil
level is checked and displayed via a scale.
Gasoline engine:
If the engine oil level reaches the minimum
level, a check control message is displayed.
Diesel engine:
During the measurement, the idle speed is in‐
creased somewhat.
General information
A detailed measurement is only possible with
certain engines.
Requirements▷Vehicle is on level road.▷Selector lever in selector lever position N
or P and accelerator pedal not depressed.▷Engine is running and is at operating tem‐
perature.

CoolantVehicle 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.
Information WARNING
With the engine hot and the cooling sys‐
tem open, coolant can escape and lead to
burns. There is risk of injuries. Only open the
cooling system with the engine cooled down.◀
WARNING
Additives are harmful and incorrect addi‐
tives can damage the engine. There is risk of
injuries and risk of property damage. Avoid the
contact of articles of clothing, skin or eyes with
additives. Do not swallow any additives. Use
suitable additives only.◀
Coolant consists of water and additives.
Not all commercially available additives are
suitable for the vehicle. Information about suit‐
able additives is available from a dealer’s serv‐
ice center or another qualified service center or
repair shop.
Coolant level
General information
Vehicles with gasoline engine feature two
cooling circuits. Always check the coolant lev‐els of both coolant reservoirs and refill as
needed.
The coolant level is indicted using minimum
and maximum markings. Depending on the
coolant reservoir, the minimum and maximum
markings are located at different locations.
Overview
Opening the hood, refer to page 272
Depending on the engine installation, the cool‐
ant reservoir is located on the right side or the
left side of the engine compartment, refer to
page 271.

Lights and bulbs
General information
Lights and bulbs make an essential contribu‐
tion to vehicle safety.
All headlights and lights are made using LED
or laser technology.
The vehicle manufacturer recommends that
you let a dealer’s service center or another
qualified service center or repair shop perform
the work in case of a malfunction.
Information
Lights and bulbs DANGER
There can be high voltage in the lighting
system. There is danger to life. The manufac‐
turer of your vehicle recommends that the
work on the lighting system including bulb re‐
placement be performed by a dealer’s service
center or another qualified service center or re‐
pair shop.◀
Light-emitting diodes (LEDs)
Some items of equipment use light-emitting
diodes installed behind a cover as a light
source.
These light-emitting diodes, which are related
to conventional lasers, are officially designated
as Class 1 light-emitting diodes.
WARNING
Too intensive brightness can irritate or
damage the retina of the eye. There is risk of
injuries. Do not look directly into the headlights
or other light sources for an extended period of
time. Do not remove the LED covers.◀
Headlight glass
Condensation can form on the inside of the ex‐
ternal lights in cool or humid weather. When
driving with the lights switched on, the con‐densation evaporates after a short time. The
headlight glass does not need to be changed.
If despite driving with the lights switched on,
increasing humidity forms, e. g. water droplets
in the lamp, the manufacturer of your vehicle
recommends having it checked by a dealer’s
service center or another qualified service cen‐
ter or repair shop.
Changing wheels
Information When using run-flat tires or sealants, a tire
does not need to be changed immediately in
the event of pressure loss due to a flat tire.
The tools for changing wheels are available as
accessories from your dealer’s service center
or another qualified service center or repair
shop.
