Battery acid is caustic. #
Avoid contact with the skin, eyes or

Always allow a battery tothaw before
ch arging it or per form ing starting assis‐

very likely that the discharged battery
has frozen.
In this case, obser vethefo llowing points:
R Do not give theve hicle starting assis tance or

While driving, pay attention tovibrations, noises
and unusual driving characteristics, e.g. pulling to

or tires. If you suspect that a tire is defective,
re duce your speed. Stop theve hicle as soon as
possible tocheck if wheels and tires ha vebeen

WARNING Risk of accident from dam‐

Dama ged tires can cause tire pressure loss.
As a result, you could lose control of your
ve hicle. #
Check the tires regularly for signs of
dama geand replace any damaged tires
immediatel y. Check
the wheels and tires of your vehicle for
damage regular ly, i.e. at least every two weeks,
as well as af ter driving off-road or on rough

R Punctures in the tires
R Tears in the tires
R Bulges on tires
R Deformation or se vere cor rosion on wheels &
WARNING Risk ofhydroplaning because
tire tread is too low
Insuf ficient tire tread will result in reduced
tire traction. The tire tread will no longer be
able todissipate water.
This increases therisk of hydroplaning on wet
