Switching off the engine
Important safety notesGWARNING
If the engine is not running, there is no power
assistance for the steering and brakes.
Steering and braking then requires
significantly greater effort.
As a result, you could cause an accident and
injure yourself and others.
Therefore, do not switch off the engine while
you are driving.
! Do not open the driver's door while the
vehicle is in motion. At low speeds in
transmission position D or R, park position
P is otherwise engaged automatically. This
can damage the transmission.

General information
GWARNING
When you leave the vehicle, you should
always remove the SmartKey from the ignition
and take it with you, remembering to lock the
vehicle. Do not leave children unattended in
the vehicle and do not give them access to the
unlocked vehicle. The children could release
the parking brake and/or shift the

Driving tips
General driving tips
Important safety notes
GWARNING
Please do not forget that your primary
responsibility is to drive the vehicle. A driver's
attention to the road must always be his/her
primary focus when driving. For your safety
and the safety of others, we recommend that
you pull over to a safe location and stop
before placing or taking a telephone call.
If you choose to use the telephone 9
while
driving, please use the hands-free device and
only use the telephone when road, weather
and traffic conditions permit. Some
jurisdictions prohibit the driver from using a
mobile telephone while driving a vehicle.
Only operate the COMAND 9
(Cockpit
Management and Data System) if road,
weather and traffic conditions permit.
Otherwise, you may not be able to observe
traffic conditions and could endanger yourself
and others.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
Drive sensibly – save fuel
Observe the following tips to save fuel:
XThe tires should always be inflated to the
recommended tire pressure.XRemove unnecessary loads.XWarm up the engine at low engine speeds.XAvoid frequent acceleration or braking.XHave all maintenance work carried out
according to the service intervals listed inthe Maintenance Booklet or the service
interval display.
Fuel consumption also increases when
driving in cold weather, in stop-and-go traffic
and in mountainous terrain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment.
The possibility of a serious or even fatal
accident are greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Pedals
GWARNING
Make sure absolutely no objects are
obstructing the pedals' range of movement.
Keep the driver's footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure that the
pedals still have sufficient clearance.
During sudden driving or braking maneuvers,
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.
Rolling with the engine switched off
GWARNING
There is no power assistance for the steering
and the brake when the engine is not running.
Steering and braking requires significantly
more effort and you could lose control of the
vehicle and cause an accident as a result.

If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and the child could be burned on these
parts.GWARNING
Never touch the heating element or sides of
the lighter; they are extremely hot. Hold the
knob only.
Make sure any children traveling with you do
not injure themselves or start a fire with the
hot cigarette lighter.

Points to observe before use
The sockets can be used for accessories with
a maximum current draw of 180 W (15 A), e.g.
lamps or chargers for mobile phones.
If you use the sockets for long periods when
the engine is switched off, the battery may
discharge.
i You can also use the sockets when the
ignition is switched off. An emergency cut-
out ensures that the on-board voltage does
not drop too low. If the on-board voltage is
too low, the power to the sockets is
automatically cut. This ensures that there
is sufficient power to start the engine.
