The concept
The Check Control system monitors functions
in the vehicle and notifies you of malfunctions in
the monitored systems.
A Check Control message is displayed as a
combination of indicator or warning lamps and
text messages in the instrument cluster and in
the Head-up Display.
In addition, an acoustic signal may be output and
a text message may appear on the Control Dis‐
play.Indicator/warning lamps
The indicator and warning lamps can light up in
a variety of combinations and colors.

consumption1."Settings"2."Info display"3."Additional indicators"
The bar display for the current fuel consumption
is displayed in the instrument cluster.
Energy recovery The energy of motion of the ve‐
hicle is converted to electrical en‐
ergy while coasting. The vehicle
battery is partially charged and
fuel consumption can be low‐
ered.
Service requirements
Display The driving distance or the time

mandated inspections of the vehicle are auto‐
matically transmitted to your service center be‐
fore a service due date, Automatic Service Re‐
quest, refer to page  250.

Information in detail
Range
Displays the estimated cruising range available
with the remaining fuel.
It is calculated based on your driving style over
the last 20 miles/30 km. If there is only enough
fuel left for less than 45 miles/80 km, the color
of the display changes.
Average fuel consumption
This is calculated for the period during which the
engine is running.
The average fuel consumption is calculated on
the basis of various distances.
Average speed
Periods in which the vehicle is parked with the
engine manually stopped do not enter into the
calculation of the average speed.
Resetting average values
Press and hold the computer button on the turn
signal lever.
Distance to destination
The distance remaining to the destination is dis‐
played if a destination is entered in the naviga‐
tion system before the trip is started.
The distance to the destination is adopted au‐
tomatically.
Time of arrival The estimated time of arrival is
displayed if a destination is en‐
tered in the navigation system
before the trip is started.
The time must be correctly set.
Speed limit

Saving fuelVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions 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.
The implementation of certain measures, driv‐
ing style and regular maintenance can have an
influence on fuel consumption and on 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
raises fuel consumption.
Check the tire inflation
pressure regularly
Check and, if necessary, correct the tire inflation
pressure at least twice a month and before start‐
ing on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away without delay
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 fastest way for the cold engine to
reach its operating temperature.
Look well ahead when driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehicle
driving ahead of you.
Driving smoothly and looking ahead reduces
fuel consumption.
Use coasting conditions
When approaching a red light, take your foot off
the accelerator and let the vehicle coast to a halt.
On a downhill gradient, take your foot off the ac‐
celerator and let the vehicle roll.Seite 164Driving tipsSaving fuel164

Engine oilVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
General information
The engine oil consumption is dependent on the
driving style and driving conditions.
Therefore, regularly check the engine oil level
after refueling.
Check oil level
The concept
The oil level is monitored electronically and dis‐
played on the Control Display.
Requirements▷The engine must be running and warm after
the vehicle has been driven for at least
6 miles/10 km.▷The vehicle is stopped or being driven on a
level roadway.
Displaying the oil level

Possible messages
▷"Engine oil level OK"▷"Measurement not possible at this time."▷"Measuring engine oil level..."Duration with the engine running: ap‐
prox. 3 minutes.
Duration while driving: approx. 5 minutes.▷"Engine oil level below minimum. Add 1
quart!"
Add oil within the next 125 miles/200 km.▷"Engine oil level too high! Have this
checked."
Have the vehicle checked immediately.
Too much engine oil
Have the vehicle checked immedi‐
ately; otherwise, surplus oil can lead to en‐
gine damage.◀▷"Measurement inactive. Have this
checked."
Note the newly calculated remaining mile‐
age until the next oil service. Have the sys‐
tem checked as soon as possible.
Adding engine oil
Filler neck
When the indicator lights up in the instrument
cluster, add 1 US quart/liter of engine oil within
the next 125 miles/200 km.
