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 depress it before the vehicle begins to
roll. G
WARNING
After a short time, hill start assist will no lon-
ger 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.
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 a
downhill gradient.
R on vehicles with automatic transmission,
the transmission is in position N.
R the parking brake is engaged.
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 The ECO start/stop function switches the
engine off automatically if the vehicle stops
moving.
When pulling away again, the engine starts
automatically. The ECO start/stop function
thereby helps you to reduce the fuel con-
sumption and emissions of your vehicle.
Every time you switch on the engine using the
key or the Start/Stop button, the ECO start/
stop function is activated.
The system is operational when the
¤
symbol is shown in green in the multifunction
display.
If not all conditions for automatic engine
switch-off are fulfilled (Y page 151), the
¤ symbol is shown in yellow in the multi-
function display.
If the ECO start/stop function has been man-
ually deactivated (Y page 150) or a malfunc-
tion has caused the system to be deactivated,
the ¤ symbol is not displayed.

If not all conditions for automatic engine
switch-off (Y page 151) are fulfilled, the ¤
symbol is shown in yellow in the multi-

i The engine can be switched off automat-
ically a maximum of four times (initial stop,
then three subsequent stops) in succes-
sion. The ¤symbol is shown in yellow
in the multifunction display after the engine
has been started automatically for the
fourth time. When the ¤symbol is
shown in green in the multifunction display,
automatic engine switch-off is again possi-
ble.
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 func-
tion can be deactivated by pressing the
ECO button (Y page 150).
Vehicles with manual transmission The ECO start/stop function switches off the
engine automatically at low speeds.

start. The starter motor
can be heard. R
There is a malfunction in the engine electronics.
R There is a malfunction in the fuel supply.
X Turn the key back to position 0in the ignition lock before
attempting to start the engine again.
or
X Press the Start/Stop button repeatedly until all indicator lamps
in the instrument cluster go out.
X Try to start the engine again (Y page 148). Avoid excessively
long and frequent attempts to start the engine, as this will drain
the battery.
If the engine does not start after several attempts:
X Consult a qualified specialist workshop. The engine does not
start. The starter motor
can be heard. The
reserve fuel warning
lamp is lit and the fuel
gauge display shows
0. The fuel tank is empty.
X
Refuel the vehicle. The engine does not
start. You cannot hear
the starter motor. The on-board voltage is too low because the battery is too weak
or discharged.
X
Jump-start the vehicle (Y page 341).
If the engine does not start despite attempts to jump-start it:
X Consult a qualified specialist workshop. The starter motor was exposed to a thermal load that was too high.
X
Allow the starter motor to cool down for approximately two
minutes.
X Try to start the engine again.
If the engine still does not start:
X Consult a qualified specialist workshop. Vehicles with a petrol
engine:
The engine is not run-
ning 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.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it.
X Have the cause rectified immediately at a qualified specialist
workshop. Driving

MSolutions The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also glow 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 316). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct, the engine radiator fan may be faulty.
The coolant is too hot and the engine is no longer being cooled
sufficiently.
X
If the coolant temperature is below 120 †, you can continue
driving to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving in
mountainous terrain and stop-start traffic. Manual transmission
Gear lever
Gear lever
!
Only engage gear when the clutch pedal
is depressed.
! When shifting between 5thand 6thgear,
you should always push the gear lever all
the way to the right. Otherwise, you could
shift unintentionally into 3rdor4th gear
and damage the transmission.
If you shift down at too high a speed (trans-
mission braking), this can cause the engine
to overrev, leading to engine damage.
Do not use the clutch bite point to keep the
vehicle stationary on uphill gradients. There is otherwise a risk of damaging the
clutch.
! On long and steep downhill gradients,
especially if the vehicle is laden or towing
a trailer, you must shift into gear 1, 2or3
in good time. This uses the engine's braking
effect. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. Shifting to neutral (N)
X
Depress the clutch pedal fully.
X Move the gear lever to position N:. 154

In the automatic drive program, you can
restrict or expand the shift range by using the
steering wheel gearshift paddles
(Y page 159).
In the manual drive program, you can change

Drive program Eis characterised by the fol-
lowing:
R comfort-oriented engine and automatic
transmission settings
R optimal fuel consumption resulting from
the automatic transmission shifting up
sooner
R the vehicle pulling away more gently in
forward and reverse gears, unless the
accelerator pedal is depressed fully
R increased sensitivity. This improves driving
stability on slippery road surfaces, for
example
R the automatic transmission shifting up
sooner. This results in the vehicle being
driven at lower engine speeds and the
wheels being less likely to spin Shift ranges
Introduction When the automatic transmission is in posi-
tion
D, it is possible to restrict or expand the
shift range (Y page 159).
The shift range selected is shown in the mul-
tifunction display. The automatic transmis-
sion shifts only as far as the selected gear. Shift range

engine on extremely steep downhill
gradients and on long downhill

Restricting the shift range
X
Pull the left-hand steering wheel gearshift
paddle.
The automatic transmission shifts down
one gear and restricts the shift range to the
relevant gear.
i If the engine exceeds the maximum
engine speed when shifting down, the auto-
matic transmission protects against engine
damage by not shifting down.
i If the maximum engine speed for the shift
range is reached and you continue to accel-
erate, the automatic transmission shifts up
in order to prevent the engine from over-
revving, even if the shift range is restricted. Automatic transmission
