Starting procedure with the Start/Stop button The Start/Stop button is only available on
vehicles with KEYLESS-GO or the KEYLESS-
GO start function.
The Start/Stop button can be used to start
the vehicle manually without inserting the key
into the ignition lock. The key must be in the
vehicle and the Start/Stop button must be
inserted in the ignition lock. This mode for
starting the engine operates independently of the ECO start/stop automatic engine start
function.
You can start the engine if a valid key is in thevehicle. Switch off the engine and always take
the key with you when leaving the vehicle,
even if you only leave it for a short time. Pay
attention to the important safety notes.
X Depress the brake pedal and keep it
depressed.
X To start a petrol engine: press the Start/
Stop button once (Y page 181).

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 Remove your foot from the brake pedal.
The vehicle is then held for about a second.

Problem
Possible causes/consequences and
M
MSolutions 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. The coolant tempera-
ture display is showing
more than 120 †. A
display message may
also appear in the mul-
tifunction display 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 393). 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
! 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, 2or3in
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. k

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 neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is a risk of an
accident.
After switching off the engine, always switch
to parking position P. Prevent the parked vehi-
cle from rolling away by applying the parking
brake.
Bear in mind that power transmission
between the engine and the transmission is
interrupted when the engine is switched off.
For this reason, shift the automatic transmis-
sion to Pwhen the engine is switched off and
the vehicle is stationary. Apply the electric
parking brake to prevent the vehicle from roll- ing away.

Driving tips
Changing gear The automatic transmission shifts to the indi-
vidual gears automatically when it is in trans-
mission position D. Gearshifting is deter-
mined by:
R the selected drive program (Y page 197)
R the position of the accelerator pedal
R the road speed
Accelerator pedal position Your style of driving influences how the auto-
matic transmission shifts gear:
R little throttle: early upshifts
R more throttle: late upshifts Double-clutch function When shifting down, the double-clutch func-
tion is active regardless of the currently selec-
ted drive program. The double-clutch functionreduces load change reactions and is condu-cive to a sporty driving style. The sound gen-
erated by the double-clutch function depends
on the drive program selected.
Kickdown Use kickdown for maximum acceleration.
X Depress the accelerator pedal beyond the
pressure point.
The transmission shifts to a lower gear
depending on the engine speed.
X Ease off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Rocking the vehicle free Rocking the vehicle free by shifting the trans-
mission repeatedly between transmission
positions Dand Rmay help to free the vehicle
if it has become stuck in mud or snow.
The vehicle's engine management restricts
repeated shifting between gears Dand Rup
to a maximum speed of 9 km/h.
To shift back and forth between transmission
positions Dand R, move the DIRECT SELECT
lever up and down past the point of resist-
ance.
Towing a trailer Towing a trailer is not possible with all mod-
els. For further information, see

X Drive in the middle of the engine speed
range on uphill gradients.
X Manual shifting: depending on the uphill
or downhill gradient, shift into a gear
(Y page 198 )in which the engine will run in
the middle of the engine speed range. 196
