Repairs and technical modifications
Repairs and modifications must always be carried out according to the manufac­
turer's specifications
Unauthorized modifications to th e e lectronic
component s or software in the vehicle may
cause
E lectro nic comp o­
nents are linked toget her in networks and other
sys tems may be nega tive ly affected by improper
m odificat ions or improperly installed accesso ­
ries. Thi s can se riously impair safety and lead to
excessive wear o f components.
Changing the vehicle's sus pens io n system can
change the way that the Advanced
Sys tem performs in a crash. For example, usin g
t ir e-rim combinations not approved by Volk­
swagen, lower ing the vehicle, changi ng the stiff­
ness of the suspension, including the spring s,
suspension struts, shock absorbers can chan ge
the forces that are measured by the airbag sen­
so rs and sent to the con trol unit. Some su spen­
s ion changes can, for exa mpl e, incr ease the force
levels measured by the sensors and make the
airbag system dep loy in crashes in which it
wou ld not deploy if the changes had not been
made. Other kinds of changes may reduce the
force levels measured by the sensors and pre­
vent the airbag from deploying when it sho uld.
We recommend that all necessary work be per­
formed by an authorized Volkswagen deale r
using genuine Volkswagen parts ®.
WARNING
Imp roperly performed modifications or other
work that is not properly performed on your
ve hicle can cause malfunctions leading to ac­
cidents and serious pe rsonal injury.
• Never install suspension components that
d o not have the same performance character­
i stics as the components originally installed
on your vehicle. Never use tire-r im comb ina­
tions th at have not been approved by Volk­
swage n.
WARNING
Improper care, servicing and repa ir proce­
dures can increase the risk of personal injury
a nd death by preventing an a irbag from de­
p lo ying w hen needed or deploying an airbag
unexpected ly.
• Chang ing th e vehicle's su spens ion in­
cluding use of unapproved t ire- rim combina­
tions can change Advanced Ai rbag perfor­
mance and increase the risk of serious per­
sona l inju ry in a crash.
