106Instruments and controlsTachometer
Displays the engine speed.
Drive in a low engine speed range for each gear as much as possible.
Caution
If the needle is in the red warning
zone, the maximum permitted
engine speed is exceeded. Engine at risk.
Fuel gauge
Displays the level in the fuel tank.
The arrow indicates the vehicle side
where the fuel filler flap is located.
Control indicator Y illuminates if the
level in the tank is low. Refuel
immediately if it flashes.
Never run the fuel tank dry.
Because of the fuel remaining in the
tank, the top-up quantity may be less
than the specified fuel tank capacity.
Engine coolant temperature
gauge
Displays the coolant temperature.

Instruments and controls107Caution
If engine coolant temperature is
too high, stop vehicle, switch off
engine. Danger to engine. Check
coolant level.
Service display
The engine oil life system informs
when to change the engine oil and
filter. Based on driving conditions, the interval at which an engine oil and
filter change will be indicated can vary
considerably.
The remaining oil life duration menu
is displayed in the Driver Information
Centre 3 114.
On Midlevel display select the
Settings Menu by pressing MENU on
the turn signal lever. Turn the adjuster wheel to select the Remaining Oil
Life page.
On Uplevel display select Info Menu
by pressing p on steering wheel.
Press P to select Remaining Oil
Life page.
Remaining oil life duration is indicated
in percentage.
Reset
On Midlevel display press SET/CLR
on turn signal lever for several
seconds to reset. The ignition must be
switched on but engine not running.
On Uplevel display press > on
steering wheel to open the subfolder. Select Reset and confirm by pressing

162Driving and operatingVehicles with automatic transmission
or manual transmission automated
If the vehicle is at a standstill with
depressed brake pedal, Autostop is
activated automatically.
The engine will be switched off while
the ignition stays on.
The stop-start system will be disabled
on inclines of 15% or more.
Indication
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
After restart, the idle speed is
indicated.
During an Autostop, the heating and
brake performance will be
maintained.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled.
● The stop-start system is not manually deactivated.
● The bonnet is fully closed.
● The driver's door is closed or the driver's seat belt is fastened.
● The vehicle battery is sufficiently charged and in good condition.
● The engine is warmed up.
● The engine coolant temperature is not too high.
● The engine exhaust temperature is not too high, e.g. after driving
with high engine load.
● The ambient temperature is above -5 °C.
● The climate control system allows an Autostop.
● The brake vacuum is sufficient.● The self-cleaning function of the diesel particle filter is not active.
● The vehicle was driven at least at
walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details 3 146.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 156.
Vehicle battery discharge protection
To ensure reliable engine restarts, several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Power saving measures
During an Autostop, several electrical
features such as auxiliary electric
heater or rear window heating are
disabled or switched to a power
saving mode. The fan speed of the
climate control system is reduced to
save power.

Vehicle care227The engine oil level must not exceed
the MAX mark on the dipstick.Caution
Overfilled engine oil must be
drained or suctioned out.
Capacities 3 287.
Fit the cap on straight and tighten it.
Engine coolant The coolant provides freeze
protection down to approx. -28 °C. In
cold regions with very low
temperatures, the factory filled
coolant provides frost protection
down to approx. -37 °C.
Caution
Only use approved antifreeze.
Coolant and antifreeze 3 273.
Coolant levelCaution
Too low a coolant level can cause
engine damage.
If the cooling system is cold, the
coolant level should be above the
filling line mark. Top up if the level is
low.
9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up, use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.

274Service and maintenanceDexos is the newest engine oil quality
that provides optimum protection for
gasoline and diesel engines. If it is unavailable, engine oils of other listed qualities have to be used.
Recommendations for gasoline
engines are also valid for
Compressed Natural Gas (CNG),
Liquified Petroleum Gas (LPG) and
Ethanol (E85) fuelled engines.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 277.
Topping up engine oil
Engine oils of different manufacturers
and brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use of engine oil with only
ACEA A1/B1 or only A5/B5 quality is
prohibited, since it can cause long-
term engine damage under certain
operating conditions.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 277.Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity grades
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature
viscosity.
Select the appropriate viscosity grade depending on the minimum ambient
temperature 3 277.
All of the recommended viscosity grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only organic acid type-long life
coolant (LLC) antifreeze approved for
the vehicle. Consult a workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. Innorthern countries with very low
temperatures the factory filled coolant
provides frost protection down to
approx. -37 °C. This concentration
should be maintained all year round.
The use of additional coolant
additives that intend to give additional corrosion protection or seal against
minor leaks can cause function
problems. Liability for consequences
resulting from the use of additional
coolant additives will be rejected.
Washer fluid
Use only washer fluid approved for
the vehicle to prevent damage of
wiper blades, paintwork, plastic and
rubber parts. Consult a workshop.
Brake and clutch fluid
Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified interval.
