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. *
NO
TEWearing out the brake linings by
continuously dep ressing the brake pedal #
Do not depress the brake pedal contin‐
uously whilst driving. #
Touse the braking ef fect of the engine,
shift toa lo werge ar in good time. *

Avoid high engine speeds and driving at
full thro ttle until the engine has reached
its operating temp erature. *

TEDama getothe catalytic con verter
due tonon-combu sted fuel The engine is not
running smo othly and is
misfiring.
Non-combus ted fuel may get into the cata‐
lytic con verter. #
Only depress the accelera tor pedal
slightl y. #
Have the cause rectified immediately at
a qu alified specialist workshop. Limited braking ef
fect on salt-trea tedro ads:
R Due tosalt build-up on the brake discs 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 preve nt salt 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

Ke ep the tire sealant away from children.
If yo u come into contact with the tire sealant,
obser vethefo llowing: #
Rinse off the tire sealant from your skin
immediately using water. #
If tire sealant gets into your eyes, thor‐
oughly rinse out theey es using clean
wate r. #
If tire sealant has been swallowe d,
immediately rinse out the mouth thor‐
oughly and drink plenty of water.Do not
induce vomiting and seek medical
attention immediately. #
Change out of any clo thes conta mina‐
te d with tire sealant immediatel y.#
If allergic reactions occur, seek medical
attention immediatel y. *

tion compressor running too long #
Do not runth e tire inflation compressor
fo r longer than eight minutes without
inter ruption. Comply with
the manufacturer's saf ety no tes on

The tires may wearexc essively and/or
une venly, which may greatlyimpair tire
traction.
R The driving characteristics, as well as
st eering and braking, may be greatly
impaired. #
Comply with there commended tire
pressure and check the tire pressure of
all tires including the spare wheel regu‐
larly:
R at least once a month
R when the load changes
R before embarking on a lon ger journey
R if operating conditions change, e.g. off-
ro ad driving #
Adjust the tire pressure as necessar y.Driving wi
thtire pressu rethat is too high or too
low can:
R Sho rten the service life of the tires.
R Cause increased tire damage. R
Adversely af fect driving characteristics and
th us driving saf ety, e.g. due to hydroplaning. &
WARNING Risk of an accident due to
insuf ficient tire pressure
Ti re s with pressure that is too low can over‐
heat and bur stas a result.
In addition, they also suf fer from excessive
and/or ir regular wear, which can significantly
impair the braking properties and the han‐
dling characteristics. #
Avoid excessively low tire pressures in
all the tires, including the spare wheel. Ti
re pressure which is too low can cause:
R Tire defects as a result of overheating
R Impaired handling characteristics
R Irre gular wear
R Increased fuel consum ption &
WARNING Risk of accident from exces‐
sive tire pressure
Ti re s with excessively high pressure can
bu rst because they are damaged more easily
by highw ayfill, pot holes etc.
In addition, they also suf fer from ir regular
we ar, which can significantly impair the brak‐
ing properties and the handling characteris‐
tics. #
Avoid excessively high tire pressures in
all the tires, including the spare wheel. Excessively high tire pressure can
result in:
R Increased braking dis tance
R Impaired handling characteristics
R Irre gular wear
R Impaired driving com fort
