Safety notes
Warning labels
G
Warning!
Various warning labels are attached to your
vehicle. These warning labels are intended to
make you and others aware of various risks.
Do not remove any of these warning labels
unless explicitly instructed to do so by
information on the label itself. Removing
warning labels may cause you and others to
be unaware of certain risks which may result
in an accident and/or personal injury.
Danger of electric shock The components of the HYBRID system are
indicated by yellow warning labels to make
you aware of high voltage. High-voltage
cables are orange-colored.
G
Warning!
The HYBRID system is energized by high
voltage.
You could be seriously or even fatally injured
when you
R tamper with components or high-voltage
cables of the HYBRID system
R touch components or high-voltage cables
of the HYBRID system after the vehicle has
been involved in an accident
R touch damaged components of the HYBRID
system
Do not remove covers of components of the
HYBRID system that carry the yellow warning label. Do not tamper with any components or
with the orange high-voltage cables of the
HYBRID system.
Engine compartment
Before opening the hood do the following:
X Engage the parking brake.
X Shift the automatic transmission into park
position P.
X Switch off the ignition.
The READY indicator (Y page 16) in the
instrument cluster goes out.
X Remove the SmartKey from the starter
switch or remove the SmartKey with
KEYLESS-GO from the vehicle.
X Observe the safety notes on the danger of
electric shock in this manual.
X Observe the safety notes regarding the
hood in the Operator’s Manual. Automatic HYBRID system switch-off
The HYBRID system switches off
automatically if
R the Supplemental Restraint System (SRS)
activates the restraint systems in an
accident
R a short circuit in the HYBRID system is
detected
R a plug connection of the HYBRID system is
disconnected
These measures help to prevent you from
coming into contact with high voltage. High-voltage battery
G
Warning!
The high-voltage battery of the HYBRID
system is located under the cargo
compartment. When the pressure inside the
high-voltage battery exceeds a certain value, 8

Safety notes
G
Warning!
When your vehicle is in electric drive mode the
engine produces significantly lower noise
levels. Other motorists or pedestriants,
especially those who are visually or hearing
impaired, may be unable to hear your vehicle
while it is in motion. This is particularly true
when driving at lower speeds and during
parking maneuvers. At all times, it is the
responsibility of the driver to be aware of their
surroundings, especially in these low speed
situtations. Otherwise other road users could
be seriously or fatally injured. G
Warning!
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 the pedals
still have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between or
under the pedals. You could then no longer
brake or accelerate. This could lead to
accidents and injury.
Starting the engine
:
READY indicator
X Switch on the ignition.
X Apply the brake pedal fully and release it.
The self-test of the RBS is completed. For
more information on the RBS, see
(Y page 9).
X Observe the notes on “Starting the engine”
in the Operator’s Manual and start the
combustion engine.
Silent-Start mode
The combustion engine may not start each
time you start the vehicle with the SmartKey
or with KEYLESS-GO.
Depending on various conditions such as the
charging level of the high-voltage battery, you
may drive off with electrical energy alone. The
vehicle is then in Silent-Start mode. The
READY indicator : will then indicate that the
HYBRID systems are operational. 16

Make sure the cable clamps do not touch
any other metal part while the other end is
still attached to a battery.
Connecting the jumper cables
Your vehicle is equipped with two jump start
terminals in the engine compartment.
Position
C represents the charged battery of
another vehicle or an equivalent starter pack.
X Make sure the two vehicles do not touch.
X Switch off all electrical consumers.
X Engage the parking brake.
X Make sure the automatic transmission is in
park position P.
X Open the hood, see Operators' Manual.
X Flip up cover : of positive terminal = in
direction of arrow.
X Connect positive terminal ; of charged
battery C with positive terminal = with a
jumper cable. Clamp the cable to positive
terminal ; of charged battery C first.
X Slide cover A from negative terminal B in
direction of arrow.
X Connect negative terminal ? of charged
battery C with negative terminal B with a jumper cable. Clamp the cable to
negative terminal ? of charged battery
C first. Starting the combustion engine
X Start the engine of the vehicle with the
charged battery and run it at an engine
speed slightly above idle speed.
X Make sure the automatic transmission is in
park position P.
X Starting the jump start process with
the SmartKey: To start the charging
process for the high-voltage battery, turn
the SmartKey in the starter switch first into
starting position 3.
X Turn the SmartKey back into ignition
position 2.
X Starting the jump start process with
KEYLESS-GO: Depress the brake pedal
