WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only shift the automatic transmission to
the desired drive position when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. You could otherwise damage the
drive train. SmartKey positions

WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
! Do not depress the accelerator pedal
when starting the engine.
i During a cold start, the engine runs at
higher speeds to enable the catalytic
converter to reach its operating
temperature. The sound of the engine may
change during this time.

temperature more quickly.
Hill starta ssist G
WARNING
After a short time, hill start assist will no
longer brake your vehicle and it could roll
away. There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient.
It holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and to depress it before the vehicle begins to
roll. X
Take your foot off the brake pedal.
The vehicle is then held for about a second.
X Pull away.
Hill start assist will not function if:
R you are pulling away on a level road or on
a downhill gradient.
R the transmission is in position N.
R the electric parking brake is applied.
R ESP ®
is malfunctioning. ECO start/stop function
Important safety notes G
WARNING
If the engine is switched off automatically and
you exit the vehicle, the engine is restarted
automatically. The vehicle may begin moving.
There is a risk of accident and injury.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.
General notes If the
¤ symbol is shown in the
multifunction display, the ECO start/stop
function switches the engine off
automatically when the vehicle stops.
The engine starts automatically when the
driver wants to pull away again. The ECO
start/stop function thereby helps you to
reduce the fuel consumption and emissions
of your vehicle.
The stop/start function is automatically
activated each time you start the engine with
the SmartKey.
If the ECO start/stop function has been
manually deactivated (Y page 130) or a
malfunction has caused the system to be
deactivated, the ¤symbol is not

Automatic engine switch-off
General notes
The ECO start/stop function is operational
and the
¤symbol is displayed in the
multifunction display, if:
R the indicator lamp in th eECO butto nis lit
green.
R the outside temperature is within the
comfort range.
R the engine is at normal operating
temperature.
R the set temperature for the vehicle interior
has been reached.
R the battery is sufficiently charged.
R the system detects that the windshield is
not fogged up when the air-conditioning
system is switched on.
R the hood is closed.
R the driver's door is closed and the driver's
seat belt is fastened.
If conditions for automatic engine switch-off
have not been fulfilled, the ¤symbol will
not be shown.
i All of the vehicle's systems remain active
when the engine has been stopped
automatically.
i The engine can be switched off
automatically a maximum of four times
(first stop and three subsequent stops) in
succession. Automatic engine switch-off is
possible againo nce the ECO symbol
appears in the multifunctio ndisplay.
i During automatic engine switch-off, the
climate control system only operates at a
reduced capacity. If you require full climate
control capacity, the ECO start/stop
function can be deactivated by pressing the
ECO button (Y page 130).
Vehicles with automatic transmission
If the vehicle is braked to a standstill in Dor
N, the ECO start/stop function switches off
the engine automatically. i
You can still activate the HOLD function
when the vehicle is stationary, even if the
engine has been switched off
automatically. It is then not necessary to
continue applying the brakes during the
automatic stop phase. When you depress
the accelerator pedal, the engine starts
automatically and the braking effect of the
HOL Dfunction is deactivated. Depress the
accelerato rpedal carefully, as the engine
must be started first.
Automatic engine start General notes
The engine starts automatically if:
R
you switch off the ECO start/stop function
by pressing the ECO button.
R you engage reverse gear R.
R the vehicle starts to roll.
R the brake system requires this.
R the temperature in the vehicle interior
deviates from the set range.
R the system detects moisture on the
windshield when the air-conditioning
system is switched on.
R the charge level of the battery is too low.
R the driver's seat belt is removed or the
driver's door is opened.
Vehicles with automatic transmission
The engine is started automatically if you:
R release the brake pedal when HOLD is not
activated and the transmission is in
position Dor N
R depress the accelerator pedal
R move the transmission out of position P.
i Shifting the transmission to position P
does not start the engine.
i If you shift the transmission from Rto D,
the ECO start/stop function is available
again as soon as the ¤symbol
reappears in the multifunction display. Driving

Problem Possible causes/consequences and
M Solutions
The engine is not
running smoothly and
is misfiring. There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
X
Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at a qualified specialist
workshop.
Otherwise, non-combusted fuel may get into the catalytic
converter and damage it. The coolant
temperature display is
showing more than
248 ‡ (120 †). The
coolant warning lamp
may also be lit and a
warning tone may
sound. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X
Stop as soon as possible and allow the engine and the coolant
to cool down.
X Check the coolant level (Y page 263). Observe the warning
notes as you do so and add coolant if necessary. Automatic transmission

WARNING
If the engine speed is above the idling speed
and you engage transmission position Dor
R, the vehicle could pull away suddenly. There
is a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do
not simultaneously accelerate. G
WARNING
The automatic transmission switches to
neutral position Nwhen you switch off the
engine. The vehicle may roll away.T here is a
risk of an accident.
After switching off the engine, always switch
to parking position P. Prevent the parked
vehicle from rolling away by applying the
parking brake. G
WARNING
The clutch may overheat if you hold the
vehicle stationary on uphill gradients by depressing the accelerator pedal. If the clutch
does overheat, a warning tone sounds and a
display message is shown in the multifunction
display.T
he frictional connection of the clutch
may then be interrupted. The vehicle may roll
away.A s a result, you could cause an
accident.
You will only be able to continue your journey
once the clutch has cooled down and the
display message in the multifunction display
has disappeared.
Never hold the vehicle stationary on uphill
gradients by depressing the accelerator.
Instead, only ever hold the vehicle stationary
on uphill gradients by:
R depressing the brake pedal
or
R activating the HOLD function
or
R engaging the electric parking brake 132
