The vehicle is locked automatically when the
ignition is switched on and the wheels are turn-
ing.
You could therefore be locked out if:
Rthe vehicle is being pushed
Rthe vehicle is being towed
Rthe vehicle is on a roller dynamometer
iYou can activate and deactivate the auto-
matic locking mechanism via the multimedia
system (see the Digital Operator's Manual).
Unlocking/locking the driver's door
using the mechanical key
To completely lock the vehicle using the
mechanical key:
Rbegin by pressing the button for locking the
vehicle from the inside while the driver's door
is open
Rthen, proceed to lock the driver's door using
the mechanical key
XInsert the mechanical key as far as it will go
into opening :in the protective cap.
XPull and hold the door handle.

as straight as possible away from the vehicle
until it releases.
XRelease the door handle.
XTo unlock: turn the mechanical key counter-
clockwise as far as it will go to key position
1.
XTo lock: turn the mechanical key clockwise as
far as it will go to key position 1.
XCarefully press the protective cap onto the

Trunk
Important safety notes
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the
trunk lid is open when the engine is running,
especially if the vehicle is in motion. There is a
risk of poisoning.
Always switch off the engine before opening
the trunk lid. Never drive with the trunk lid
open.
GWARNING
If objects, luggage or loads are not secured or
not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, particu-
larly in the event of sudden braking or a sud-
den change in direction.

cally if the vehicle reaches a speed of above
6 mph (10 km/h) again after a full brake appli-
cation.
iThe hazard warning lamps still operate if the
ignition is switched off.
Adaptive Highbeam Assist
General notes
You can use this function to set the headlamps
to change between low beam and high beam
automatically. The system recognizes vehicles
with their lights on, either approaching from the
opposite direction or traveling in front of your
vehicle, and consequently switches the head-
lamps from high beam to low beam.
The system automatically adapts the low-beam
headlamp range depending on the distance to
the other vehicle. Once the system no longer
detects any other vehicles, it reactivates the
high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control panel.
Important safety notes
GWARNING
Adaptive Highbeam Assist does not recognize
road users:
Rwho have no lights, e.g. pedestrians
Rwho have poor lighting, e.g. cyclists
Rwhose lighting is blocked, e.g. by a barrier

Starting procedure with the Start/Stop
button
The Start/Stop button can be used to start the
vehicle manually without inserting the SmartKey
into the ignition lock. You merely need to carry
the SmartKey on your person. This mode for
starting the engine operates independently of
the ECO start/stop automatic engine start func-
tion.
You can start the engine if a valid SmartKey is in
the vehicle. Switch off the engine and always
take the SmartKey with you when leaving the
vehicle, even if you only leave it for a short time.
Pay attention to the important safety notes.
XDepress the brake pedal and keep it
depressed.
XPress the Start/Stop button once
(Ypage 110).
The engine starts.
Starting procedure with the SmartKey
XTurn the SmartKey to position 3in the igni-
tion lock (Ypage 111) and release it as soon
as the engine is running.
If the engine will not start:
XRemove the SmartKey from the ignition lock.
XReinsert the SmartKey into the ignition lock
after a short waiting period.
XTurn the SmartKey to position 2in the igni-
tion lock (Ypage 111).

Pulling away
General notes
GWARNING
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.
Depress the accelerator carefully when pulling
away.
The vehicle locks centrally once you have pulled
away. The locking knobs in the doors drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature (
Ypage 72).
It is only possible to shift the transmission from
position jto the desired position if:
Rthe engine is running and
Ryou depress the brake pedal
If you do not depress the brake pedal, the E-
SELECT lever can still be moved but the parking
lock remains engaged.
Information on the automatic release of the
electric parking brake (
Ypage 130).
Hill start assist
Hill start assist helps you when pulling away
forward 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.

ProblemPossible causes/consequences andMSolutions
The engine is not running
smoothly and is misfir-
ing.There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
XOnly depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it.
XHave the cause rectified immediately at a qualified specialist work-
shop.
The coolant temperature
display shows a value
above 248 ‡ (120 †).The coolant level is too low. The coolant is too hot and the engine is no
longer being cooled sufficiently.
XStop as soon as possible and allow the engine and the coolant to
cool down.
XCheck the coolant level (Ypage 238). Observe the warning notes
as you do so and add coolant if necessary.

Shifting gears
If you pull on the left-hand or right-hand steering
wheel paddle shifter, the automatic transmis-
sion switches to temporary manual drive pro-
gram for a limited amount of time. Depending on
which steering wheel paddle shifter is pulled,
the automatic transmission immediately shifts
into the next gear down or up, if permitted.
XTo shift up: pull the right-hand steering wheel
paddle shifter (Ypage 121).
The automatic transmission shifts up to the
next gear.
If the maximum engine speed in the currently
engaged gear is reached and you continue to
accelerate, the automatic transmission auto-
matically shifts up in order to prevent engine
damage.
The automatic transmission will not shift up to
the next gear when the engine speed is very
low.
XTo shift down: pull on the left-hand steering
wheel paddle shifter (Ypage 121).
The automatic transmission shifts down to
the next gear.
If the engine were to exceed the maximum
engine speed when shifting down, the auto-
matic transmission protects against engine
damage by not shifting down.
Automatic down shifting occurs when coast-
ing.
When using kickdown, the automatic trans-
mission automatically shifts to a lower gear.
Deactivating
If you have activated temporary manual drive
program, it will remain active for a certain
amount of time. Under certain conditions, the
minimum amount of time is extended, e.g. in the
case of lateral acceleration, during overrun
mode or when driving on steep terrain.
When temporary manual drive program is deac-
tivated, the automatic transmission shifts into
the automatic drive program that was last selec-
ted. You can also deactivate temporary manual drive
program yourself:
XPull on the right-hand steering wheel paddle
shifter and hold it in place (Ypage 121).
or
XUse the DYNAMIC SELECT controller to
change the drive program (Ypage 116).
Temporary manual drive program is deactiva-
ted. The automatic transmission switches
into the automatic drive program that was last
selected.
Manual mode
General notes
In manual mode M, you can permanently change
gear yourself by using the steering wheel paddle
shifters. The transmission must be in position
h to do this.
The switching times correspond to the previ-
ously active automatic drive program.
The transmission only shifts down automatically at low engine speeds depending on the respec-
tive gear.
In addition to manual mode M, you can also
activate temporary manual drive program
(
Ypage 122).
Activating
In manual mode M, you can change gear your-
self using the steering wheel paddle shifters if
the transmission is in position h. You can see
the currently selected drive program and which gear is engaged in the multifunction display.
XPress the M button (Ypage 121).
M is shown in the multifunction display and
the indicator lamp on the M button lights up.
