▷After approx. 8 minutes.▷When the vehicle is locked using the central
locking system.▷Shortly before the battery is discharged
completely, so that the engine can still be
started.
The radio-ready state remains active if, for ex‐
ample, the ignition is automatically switched off
for the following reasons:
▷Opening or closing the driver's door.▷Unfastening of the driver's safety belt.▷When automatically switching from low
beams to parking lights.
If the engine is switched off and the ignition is
switched on, the system automatically switches
to the radio-ready state if the lights are turned
off or, if correspondingly equipped, the day‐
time running lights are activated.
Starting the engine
Information DANGER
If the exhaust pipe is blocked or ventila‐
tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases con‐
tain carbon monoxide, an odorless and color‐
less but highly toxic gas. In enclosed areas, ex‐
haust gases can also accumulate outside of the
vehicle. There is danger to life. Keep the ex‐
haust pipe free and ensure sufficient ventila‐
tion. ◀
WARNING
An unsecured vehicle can begin to move
and possibly roll away. There is risk of an acci‐
dent. Before exiting, secure the vehicle against
rolling.
In order to ensure that the vehicle is secured
against rolling away, observe the following:
▷Set the parking brake.▷On uphill grades or on a downhill slope,
turn the front wheels in the direction of the
curb.▷On uphill grades or on a downhill slope,
also secure the vehicle, e.g., with a wheel
chock. ◀
ATTENTION
In the case of repeated starting attempts
or repeated starting in quick succession, the
fuel is not burned or is inadequately burned.
The catalytic converter can overheat. There is a
risk of damage to property. Avoid repeated
starting in quick succession. ◀

FuelVehicle features and op‐
tions
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 sys‐
tems. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive features and systems.
Fuel recommendation General information Depending on the region, many gas stations
sell fuel that has been customized to winter or
summer conditions. Fuel that is available in
winter helps make a cold start easier, for exam‐
ple.
Information ATTENTION
Even fuels that conform to the specifica‐
tions can be of low quality. This may cause en‐
gine problems, e.g., poor engine start-up be‐
havior, poor handling and/or poor
performance. There is a risk of damage to
property. In case of engine problems, switch
gas stations or use a brand name fuel with a
higher octane rating. ◀
Gasoline
General information For the best fuel efficiency, the gasoline should
be sulfur-free or very low in sulfur content.Fuels that are marked on the gas pump as con‐
taining metal must not be used.
Fuels with a maximum ethanol content of
25 %, i. e. E10 or E25, may be used for refuel‐
ing.
Ethanol should meet the following quality
standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: comply with the current standard in each
case.
Information ATTENTION
Do not press the Start/Stop button after
refueling with the wrong fuel. Furthermore, the
catalytic converter is permanently damaged.
There is a risk of damage to property. Do not
refuel or add the following in the case of gaso‐
line engines:▷Leaded gasoline.▷Metallic additives, e.g., manganese or iron.
Do not press the Start/Stop button after refuel‐
ing with the wrong fuel. Contact a dealer’s serv‐
ice center or another qualified service center or
repair shop. ◀
ATTENTION
Incorrect fuels can damage the fuel sys‐
tem and the engine. There is a risk of damage
to property. Do not use a fuel with a higher
ethanol percentage than recommended or one
with other types of alcohol, e.g., M5 to M100. ◀
ATTENTION
Fuel that does not comply with the mini‐
mum quality can compromise engine function
or cause engine damage. There is a risk of
damage to property. Do not fill with fuel that
does not comply with the minimum quality. ◀

ATTENTION
Too much engine oil can damage the en‐
gine or the catalytic converter. There is a risk of
damage to property. Do not add too much en‐
gine oil. When too much engine oil is added,
have oil level corrected by a dealer’s service
center or another qualified service center or re‐
pair shop. ◀
Detailed measurement
The concept
In the detailed measurement the engine oil
level is checked when the vehicle is stationary,
and displayed via a scale.
If the engine oil level reaches the minimum
level, a check control message is displayed.
During the measurement, the idle speed is in‐
creased somewhat.
Requirements▷Vehicle is parked in a horizontal position.▷Manual transmission: shift lever in neutral
position, clutch and accelerator pedals not
depressed.▷Steptronic transmission: selector lever in se‐
lector lever position N or P and accelerator
pedal not depressed.▷Engine is running and is at operating tem‐
perature.
Performing a detailed measurement
On the Control Display:
1. "Vehicle info"2."Vehicle status"3. "Measure engine oil level"4."Start measurement"
The engine oil level is checked and displayed
via a scale.
Time: approx. 1 minute.
Adding engine oil
Information WARNING
Operating materials, e.g., oils, greases,
coolants, fuels, can contain harmful ingredi‐
ents. There is a risk of injury or danger to life. Observe the instructions on the containers.Avoid the contact of articles of clothing, skin or
eyes with operating materials. Do not refill op‐
erating materials into different bottles. Store
operating materials out of reach of children. ◀
ATTENTION
Too low of an engine oil level causes en‐
gine damage. There is a risk of damage to
property.
Add engine oil within the next
125 miles/200 km. ◀
ATTENTION
Too much engine oil can damage the en‐
gine or the catalytic converter. There is a risk of
damage to property. Do not add too much en‐
gine oil. When too much engine oil is added,
have oil level corrected by a dealer’s service
center or another qualified service center or re‐
pair shop. ◀
General information
Only add engine oil when the message is dis‐ played in the instrument cluster. The quantity
to be added is indicated in the message dis‐
played in the instrument cluster.
Switch off the ignition and safely park the vehi‐
cle before engine oil is added.
