Have the cause rectified immediately at
a qu alified specialist workshop. Note
s on driving on salt-treated roads
The braking ef fect is limited on salt-trea ted
ro ads.
Therefore, obse rveth efo llowing no tes:
R due tosalt build-up on the brake disks and
brakepads, the braking dis tance can increase
considerab lyor result in braking only on one
side
R maintain a much greater safe dis tance tothe
ve hicle in front
To remo vesalt build-up:
R brake occasionally while paying attention to
th e tra ffic conditions
R carefully depress the brake pedal at the end
of the journey and when starting the next
journey Note
s on aquaplaning
Aq uaplaning can take place once a cer tain
amount of water has accumulated on thero ad
sur face.
Obser vethefo llowing no tes during heavy precip‐
itation or in conditions in which aquaplaning may
occur:
R reduce speed
R avoid tyre ruts
R avoid sudden steering mo vements
R brake carefully
% Also obser vethe no tes on regular lych ecking
wheels and tyres (/ page 335).
Note s on driving through water on the road
sur face
Wa ter which has entered into theve hicle can
damage the engine, electrics and transmission.
Wa ter can also enter the air intake of the engine
and cause engine damage. Obser
vethefo llowing if you must drive thro ugh
wate r:
R The water,when calm, may only reach the
lo we r edge of theve hicle body.
R Drive at walking pace at most, otherwise
wate r can enter theve hicle interior or engine
compartment.
R Vehicles tr avelling in front, or oncoming vehi‐
cles, can create waves which may exceed the
maximum permissible dep thofthewa ter.
The braking ef fect of the brakes is reduced af ter
