Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshifting the automatic transmission out of
park position P
RStart the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
GWARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
You can open a locked front door from the inside
at any time. You can open a locked sliding door
or rear door from the inside if it has been previ-
ously unlocked from inside.

If your vehicle is equipped with electrical closing
assist, you will require less force to close the
sliding door.
Electrical step
Important safety notes
!
Always observe the ground clearance of the
vehicle and avoid obstacles. On vehicles with a step, ground clearance is further restricted.
Obstacles can damage the vehicle.
If you must drive over obstacles, drive espe-
cially slowly and carefully. If necessary, have
another person direct you.
If you do not use the grab handle and the step,
you could injure yourself when getting in and out
of the vehicle.
In order to reduce risks:
Rdraw the passengers' attention to the electri-
cal step. Wait until the electrical step is fully
extended.
Rdo not jump out of the vehicle.
Ronly use the grab handle and step. Only they
are designed for such a load.
Rkeep grab handles, access steps and entry
sills free from dirt, e.g. mud, clay, snow and
ice.
Operation and obstacle detection
Electrical step
The sliding door of your vehicle can be equipped
with an electrical step.
XWhen getting in and out of the vehicle, use the grab handles and electrical step :.Electrical step
:automatically extends when
the sliding door is opened and retracts when it is
closed.
Electrical step :is equipped with an obstruc-
tion detection device on the front side. If the
step comes into contact with an obstacle while
it is extending, it stops.
After you have removed the obstacle, you must
first close the sliding door and open it once
again so that the step can extend completely.
iIf the electrical step obstructs loading, you
can prevent the step from extending when
opening the sliding door via obstacle detec-
tion. The electrical step can then remain
retracted and a forklift or other lifting equip-
ment can be moved nearer to the cargo com-
partment.
Vehicles without steering-wheel buttons: if
the 1 indicator lamp in the instrument clus-
ter lights up and a warning tone sounds, elec-
trical step :is malfunctioning (
Ypage 199).
Vehicles with steering wheel buttons: if the
Electrical
Stepmessage is shown in the dis-
play and a warning tone sounds, electrical
step :is malfunctioning (
Ypage 189).
If electrical step :is malfunctioning, the step
may only partially extend/retract or may not
extend/retract at all. If a malfunction does
occur, you will have to retract and lock electrical
step :manually before continuing the journey
(
Ypage 66).
Before passengers get out of the vehicle, let
them know that electrical step :might not be
extended.
Emergency release
!
Driving with the step extended may result in
it being damaged.
If the electrical step does not retract auto-
matically, you will have to push it in and lock it
into place manually before continuing your
journey.

Automatic headlamp mode
GWARNING
When the light switch is set to Ã, the low-
beam headlamps may not be switched on
automatically if there is fog, snow or other
causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, turn the light switch to
L.
Automatic headlamp mode is only a driving aid.
You are responsible for the vehicle lighting at all
times.
Depending on ambient light, the rain and light
sensor automatically switches on the parking
lamps, low-beam headlamps and the license
plate lamp. This excludes weather-related
impairments to visibility, such as snow, fog or
spray.
If there is fog, snow or spray, turn the light
switch quickly from ÃtoL. You could
otherwise briefly interrupt operation of the
headlamps.
XTo switch on automatic headlamp mode:
turn the light switch to Ã.

"daytime running lamps" function using the
on-board computer, the daytime running
lamps are switched on. The parking lamps and
low-beam headlamps also switch on or off
automatically, depending on the ambient
light.
When the low-beam headlamps are switched
on, the Lindicator lamp in the instrument
cluster lights up.
Fog lamps/rear fog lamp
GWARNING
If you suspect that driving conditions will be
foggy, turn the light switch to Lbefore you
start your journey. Your vehicle may other-
wise not be visible and you could endanger
yourself and others.
GWARNING
In low ambient lighting or foggy conditions,
only switch from position ÃtoL with
the vehicle at a standstill in a safe location.
Switching from ÃtoL will briefly
switch off the headlamps. Doing so while driv-
ing in low ambient lighting conditions may
result in an accident.

Operation with the remote control
Important information
You can switch the auxiliary heating on/off and
set the operating duration using the remote con-
trol. You can use up to 4 remote control units on
the vehicle. These must be synchronized for the
receiver in your vehicle (
Ypage 109).
The remote control has a maximum range of
approximately 600 meters. This range is
reduced by:
Rsources of interference
Rsolid objects between the remote control and
the vehicle
Rthe remote control being in an unfavorable
position in relation to the vehicle
Rtransmitting from an enclosed space
