bundle containing the grey wires with printing “P51” and “S807”; the second
bundle containing the three other grey wires.
e. Crimp the red wire together with the grey wires with printing “P51” and “S807” to
cable terminal 660765801 from the kit (refer to figure 6A). Cut off the eye of the
cable terminal (refer to figure 6B) and insulate the remaining part of the cable
terminal with heat shrink tubing 10811202 from the kit (refer to figure 6C).
f. Crimp the grey wires with printing “M526.1” and “M526.2” each to a cable
terminal 11060884 from the kit.
g. Locate a ground stud and secure the grey wires with printing “M526.1” and
“M526.2” to the ground stud.
h. Locate the brown 36-pin connector P51.
i. Unlock and disconnect the connector. Unlock the secondary locking device of the
connector plug by pushing the big yellow button at the plug side.
j. Remove the grey wire from contact number 3 by using removal tool
VH11063197. Cut off the cable terminal and strip back the grey wire over a
distance of 7,5 mm (0.29 inch).
k. Crimp this grey wire together with the grey wire from the kit to cable terminal
11275368 from the kit.
l. Introduce the cable terminal with the two grey wires into contact number 6 of the
connector plug.
m. Relock the secondary locking device of the connector plug by pushing in the two
small yellow buttons at the plug side. Reconnect and lock connector P51.
n. Locate dashboard switch S807 (LDW). Route the other end of the grey wire
installed in step “3.5k” to dashboard switch S807.
o. Disconnect the socket from dashboard switch S807. Remove at the back of the
socket the grey wire from contact number 7 by using removal tool VH10541368.
Secure this grey wire away with cable ties from the kit because it will not be
reconnected.
p. Introduce the female cable terminal of the grey wire installed in step “3.5k” into
contact number 7 of the socket of switch S807.
q. Secure the wires on the way with some cable ties from the kit.

f. Install 6A circuit breaker 10521076 from the kit into location 8 of fuse holder
ZB08.
g. Replace the 8A circuit breaker Z15.3 by 3A circuit breaker 10599051 from the kit.
h. Locate node 2 of the multiplex system. Disconnect 22-pin connector socket “A”
from the node by first depressing the locking tab and then carefully separating it
from the node. The connector reference (A, B, C …) has been stamped into the
node housing.
i. Fold the connector socket side covers open.
j. Install the brown wire from the kit into contact number 3 of the connector socket.
k. Close the connector socket sides and connect it again to the node.
l. Secure the ring terminal of the brown electrical wire to a ground stud in the
junction box. Secure the brown wire on the way to wiring making the same
routing with cable ties from the kit.

STEP 4 IN DETAIL: To install new support of lane-departure warning system camera on
windshield
NOTE: Never reuse a removed support! The support has inevitably been deformed at removal.
Discard the used support according to the locally applicable guidelines regarding protection of the
environment.
NOTE: To position the lane-departure warning system camera properly on the windshield, you
have to use a self-fabricated template (refer to figure 15 for the dimensions) or caliper
VH91400409 (refer to figure 16).
NOTE: The support for the lane-departure warning camera is provided with a special adhesive
layer with limited storage life. The mounting expiry date is mentioned on an adhesive label on the
support (refer to figures 8 and 9). Never install a support of which the expiry date has elapsed.

Figure 9: Mounting expiry date of support of
lane-departure warning system (typical:
February 2018)

Action
Thoroughly clean the mounting area of the camera on the windshield. To this end,
use a mix of 50% demineralized water and 50% isopropyl alcohol.
Position the lane-departure warning system camera by using the self-fabricated
template or the Van Hool caliper. Make sure that the tool fits tightly against the
windshield rubbers. Tape the tool onto the windshield.
On the interior side of the windshield, tape the template onto the windshield. Make
sure that the bottom and the non-chamfered side of the template fit tightly against the
windshield rubbers.
Remove the protective film from the adhesive layer and glue camera support
11534032 from the kit onto the windshield as indicated in figure 11.

By hand, press the support against the windshield for at least 5 seconds. This
activates the adhesive layer. Repeat this at different places over the area with
adhesive layer.
Check from the outside whether the adhesive layer is adequately glued to the
windshield all over. A single bubble is no problem, but the adhesive layer should be
glued to the windshield for at least 3/4 of its surface. Press the support some more
from inside if necessary.
NOTE: After 20 minutes, the adhesive layer reaches 50% of its adhesive force. Full
adhesive force is only obtained after a couple of hours.
Let the adhesive layer rest for approximately 20 minutes before continuing the
installation procedure of the lane-departure warning system camera.

STEP 5 IN DETAIL: To secure lane-departure warning camera into support
Step
5.1
5.2

5.3

Action
Connect the yellow 16-pin connector socket from the adapter cable to the new
camera.
Remove, if present, the protective cap from the lens. Do not touch the camera lens
with your fingers! The slightest finger print or dust on the lens can cause incorrect
warnings of the lane-departure warning system.
Starting at the bottom, install the camera in the in step 4 installed support (refer to
figure 12). Then press the top in the support until you hear a click (refer to figure 13).
The camera is now secured in the support.

Check whether the camera is introduced equally far into the support all round. The
camera is properly installed if the seam is equal all round.
