WARNING Risk of accident due tothe
brake sy stem overheating
If yo u lea veyour foot on the brake pedal
when driving, the brake sy stem may over‐
heat.
This increases the braking dis tance and the
brake sy stem may evenfa il. #
Never use the brake pedal as a foot re st. #
Do not depress the brake pedal and the
accelerator pedal at the same time
while driving. Note
s on driving with a roof load, trailer or
fully laden vehicle
When driving with a loaded roof luggage rack or
trailer as well as with a fully laden or fully occu‐
pied vehicle, theve hicle's driving and steering
ch aracteristics change. Yo
u should bear thefo llowing in mind:
R Do not exceed the permissible roof load and
to wing capacity. Also obser vethete ch nical
da ta inthe printed Owner's Manual.
R Evenly distribute thero of load, and place
heavy objects at the bottom. Also comply
with the no tes on loading theve hicle
(/ page 106).
R Drive attentivel y,and avoid sudden lypulling
aw ay, braking and steering as well as rapid
cornering.
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
conside rably or 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
