Applies to vehicles: with auxiliary heating - under development at the time of printingRemote control
The auxiliary heating and auxiliary ventilation can also be
switched on or off with the remote control.Switching on
– Press the button for about 2 seconds to activate the
auxiliary heating/ventilation ⇒fig. 125.
Switching off
– Press the button for about 2 seconds to switch
off the auxiliary heating/ventilation.Changing the battery
– Push back and remove the battery cover on the remote
control ⇒fig. 126.
– Change the battery. The diagram in the battery compart-
ment shows how the battery should be fitted. The new
battery must be of the same type as the original one.
– Re-fit the battery cover.
When it is switched on, the auxiliary heating or auxiliary ventilation
starts immediately and remains on for the period set in the menu.
The maximum running time is 60 minutes.
If you want to switch the system on again after the end of the
programmed running time, press the button .
Transmitter indicator lamp
The transmitter indicator lamp will flash accordingly to show
whether the command you sent via the remote control was
successful.
When you switch the system on by pressing the button the
indicator lamp will flash green for about 30 seconds to confirm that
the heating/ventilation has been switched on. When you switch the
system off by pressing the button the indicator lamp will
flash red to confirm that the heating/ventilation has been switched
off.
If the remote control is outside the transmitting range the indicator
lamp will flash red slowly. If there is a fault in the system (e.g. fuel
level is down to reserve), the indicator lamp will flash red rapidly. In
both cases the command will not be executed.
When the battery of the remote control is almost completely flat, the
transmitter indicator lamp will not light up and no commands will
be executed.

Technical data
Applies to vehicles: with side assistArea covered by the radar sensorsThe area covered by the radar sensors ⇒fig. 166 consists of:•
The rearward approach zone (light green area: up to about 50
metres) and
•
Blind spots (dark green area) .
The radar sensors monitor the lanes immediately to the left and
right of your vehicle. Other lanes are not covered by the sensors.Note
The side assist system is programmed for lanes of a fixed width, and
is not able to measure differing lane widths. It monitors a zone
equivalent to one normal lane width on either side. If the lanes are
narrower than this, or if vehicles are not travelling in the centre of
the lanes, the system may register vehicles that are not in fact trav-
elling in an adjacent lane ⇒page 156.Applies to vehicles: with side assistHow the system worksWhen other vehicles are detected, the side assist system registers
their distance and how fast they are approaching. The warning lamp on the relevant exterior mirror will light up whenever the side assist
calculates that the distance and the speed differential of
approaching vehicles would be critical in the event of a lane change.
The warning lamp may light up when you are being overtaken and
when you are overtaking another vehicle.
If you are overtaking slowly, with a speed differential of less than
15 km/h, the warning lamp will light up as soon as the other vehicle
enters your blind spot and is detected by the sensors. If you are
overtaking with a speed differential which is greater than this the
lamp will not give a warning.
Applies to vehicles: with side assistInformation mode and warning modeThe side assist has two modes of operation•
The information mode and
•
The warning mode
The side assist will respond in the appropriate mode, depending on
whether or not you operate the turn signal to indicate an intended
lane change.
Information mode
As long as you do not operate the turn signal, the side assist will
merely inform you of the presence of vehicles that it has detected
and judges to be critical in the event of a lane change. The warning
lamp on the relevant exterior mirror will light up with low intensity
whenever the side assist calculates that the distance and the speed
differential of an approaching vehicle are critical.
The intensity of the warning lamp in this information mode is delib-
erately kept relatively low, so that it does not distract you while you
are looking at the road in front and do not intend to change to a
different lane. The information mode is clearly visible when you look
in the exterior mirror.

Fuses and bulbs 300Fuses and bulbsFusesChanging a fuse
If a fuse has blown it must be replaced.– Identify the fuse for the failed component.
– Switch off the ignition and the component concerned.
– Remove the fuse box cover ⇒fig. 283.
– Take the plastic clip from inside the fuse cover, fit it onto
the blown fuse, and pull the fuse out.
– Replace the blown fuse (which will have a melted metal
strip) with a new fuse of the same amp rating.The various electrical circuits are protected by fuses. The fuse boxes
are located behind covers on the left and right sides of the dash
panel and in the compartment on the right side of the boot.
A plastic clip for removing the fuses is provided in the fuse cover on
the left side of the dash panel. There is also a sticker listing the fuses
in each of the fuse boxes in the dash panel.
Caution
Never attempt to “repair” a fuse or replace it by fitting a fuse with a
higher rating - risk of fire! It could also cause damage to other parts
of the electrical system.
Note
If a newly replaced fuse blows again after a short time, the electrical
system must be checked by a qualified workshop as soon as
possible.Fuses on the driver's sideSome of the items listed are only fitted on certain models or are
optional extras.
Please note that the following list, while correct at the time of
printing, is subject to alterations. If discrepancies should occur,
please refer to the sticker on the inside of the fuse cover for the
correct information for your vehicle.
