WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbit ein
the immediate vicinity of the air vents. There
is ar isk of injury.
Make sure that all vehicle occupants always
maintain asufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior. In order to ensure the direct flow of fresh air
through the air ventsi
nto the vehicle interior,
please observe the following notes:
R keep the air inlet between the windscreen
and the bonnet free of blockages, such as
ice, snow or leaves.

depress the brake pedal, the DIRECT SELECT
lever can still be moved but the parkin glock
remains engaged.
i Vehicles with automatic transmis-
sion: upshifts tak eplace at higher engine
speeds after acold start .This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill start assist Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient .It
holds the vehicle for ashort 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 ashort time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is arisk of an acciden tand 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 is not activ eif:
R you are pulling away on alevel road or a
downhill gradient
R on vehicles with automatic transmission,

Introduction The ECO start/stop function switches the
engin eoff automatically if the vehicle is stop-
ped under certain conditions. When pulling away again, the engin
estarts
automatically. The ECO start/stop function
thereby helps you to reduce the fuel con-
sumption and emission sofyour vehicle.

WARNING
If the engin eisswitched off automatically and
you exit the vehicle, the engin eisrestarted
automatically. The vehicle may begin moving. There is arisk of acciden tand injury.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.
General notes :

Hybrid vehicles: observe the notes on the
ECO start/stop function in the "HYBRID "Sup-
plement.
The ECO start/stop function is activated
whenever you start the engin eusing the key
or the Start/Stop button.
If the ¤ symbol is shown in green in the
multifunction display, the ECO start/stop
function switches the engin eoff automati-
cally if the vehicle stops moving.
If the ECO start/stop function has been man- ually deactivated (Y page 185) oramalfunc-
tion has caused the system to be deactivated, the ¤ symbol is not displayed.

start. The HOLD function or DISTRONIC PLUS is activated.
X Deactivat ethe HOLD function (Y page 228) or DISTRONIC
PLUS (Y page 224).
X Try to start the engine again. The engine does not
start. The starter motor
can be heard. R
There is amalfunction in the engine electronics.
R There is amalfunction in the fuel supply.
Before attempting to start the engine again:
X Turn the key back to position 0in the ignition lock.
or
X Press the Start/Stop button repeatedly until all indicator lamps
in the instrumen tcluster go out.
X Try to start the engine again (Y page 181). Avoid excessively
long and frequent attemptstos tart the engine, as this will drain
the battery.
If the engine does not start after several attempts: X Consult aqualified 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 405).
If the engine does not start despite attemptstoj ump-start it:
X Consult aqualified specialist workshop. The starter motor was exposed to
athermal 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:

MSolutions Vehicles with
apetrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is
amalfunction in the engine electronics or in amechanical
componentoft he 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 aqualified specialist
workshop. The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also be on 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 382). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct,t
he 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
! 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 aspeed (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 arisk 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, 2or3in
good time. This uses the engine's braking
effect.T his relieves the load on the brake
system and preventst he brakes from over-
heating and wearing too quickly. k
