Power tilt/sliding sunroof*
Opening and closing
Warning!G
When closing the tilt/sliding sunroof, make
sure that there is no danger of anyone being
harmed by the closing procedure.
If the tilt/sliding sunroof encounters an
obstruction that blocks its path in a circum-
stance where you are closing the tilt/sliding
sunroof by moving the tilt/sliding sunroof
switch past the resistance point, or by
pressing and holding button‹on the
SmartKey, by pressing and holding the lock
button (vehicles with KEYLESS-GO*) on the
door handle, the automatic reversal function
will not operate.
The opening/closing procedure of the
tilt/sliding sunroof can be immediately
halted by releasing the switch or, if the
switch was moved past the resistance point
and released, by moving the switch in any
direction.
The tilt/sliding sunroof is made out of glass.
In the event of an accident, the glass may
shatter. This may result in an opening in the
roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury
for occupants wearing their seat belts prop-
erly as entire body parts or portions of them
may protrude from the passenger compart-
ment.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock your vehicle. Do not leave children
unattended in the vehicle, or with access to
an unlocked vehicle. Unsupervised use of
vehicle equipment can cause an accident
and/or serious personal injury.!To avoid damaging the seals, do not trans-
port any objects with sharp edges which can
stick out of the tilt/sliding sunroof.
Do not open the tilt/sliding sunroof if there is
snow or ice on the roof, as this could result in
malfunctions.
The tilt/sliding sunroof can be opened or closed
manually should an electrical malfunction occur
(
page 481).
iWhen the tilt/sliding sunroof is open,
resonance noises may result in addition to the
usual wind noises. They are caused by minimal
pressure changes in the passenger compart-
ment. To reduce or eliminate theses noises,
change the position of the tilt/sliding sunroof or
open a door window slightly.
iYou can also open or close the tilt/sliding
sunroof using the SmartKey or the
KEYLESS-GO* function, see “Summer opening
feature” (
page 254) and “Convenience clos-
ing feature” (
page 256). Depending on the
current position, the tilt/sliding sunroofs may
also open or close when the air recirculation
button: on the control panel of the climate
control (
page 220) or automatic climate
control (
page 234) is pressed and held.

Warning!G
Never touch the heating element or sides of
the cigarette lighter; they are extremely hot.
Hold the knob only.
Make sure that any children traveling with
you do injure themselves or start a fire with
the hot cigarette lighter.
When leaving the vehicle always remove the
SmartKey or SmartKey with KEYLESS-GO*

!The lighter socket can accommodate 12V
DC electrical accessories (up to a maximum of
85 W) designed for use with the standard “ciga-
rette lighter” plug type. Keep in mind, however,
that connecting accessories to the lighter socket
(for example extensive connecting and discon-
necting, or using plugs that do not fit properly)
can damage the lighter socket. With the socket
damaged, the lighter may no longer be able to be
placed in the heating (pushed-in) position, or the
lighter may pop out too early with the lighter not
hot enough.
To help avoid damaging the cigarette lighter
socket, we recommend connecting 12V DC elec-
trical accessories designed for use with the stan-
dard “cigarette lighter” plug type to the
12V power outlets (
page 322) in your vehicle
whenever possible.
!The cigarette lighter is not designed for use
with the electric air pump (
page 501). Use a
power outlet (
page 322) for electric air pump
operation.
iIf the engine is off, and the cigarette lighter
is being used extensively, the vehicle battery
may become discharged.
