maximum speed in the field of vision. The sign

Wheel change between axles
Warning
A wheel change between the axles on vehi-
cles with different tire sizes or rim sizes on
the front and rear axles can cause damage
to the tires and the vehicle. There is a risk of
accident. Do not rotate the tires between the
axles on vehicles with different tire sizes or
rim sizes on the front and rear axles.
Different abrasion patterns can occur on the
front and rear axles depending on individual
driving conditions. The tires can be rotated in
pairs between the axles to achieve even abra-
sion. Further information is available from an
authorized service center or another qualified
service center or repair shop. After changing,
check the tire pressure and correct, if needed.

Safety precautions

from passing traffic and on solid ground.
▷ Turn on the hazard warning system.
▷ Secure the vehicle against rolling away by
setting the parking brake.
▷ Turn the steering wheel until the front

make sure that they remain outside the
hazardous area such as behind a guardrail.
▷ If necessary, set up a warning triangle at an
appropriate distance.
Tire repair set
Principle
With the tire repair set, minor tire damage
can be sealed temporarily to enable continued
driving.
General information
▷ The filled in tire sealant closes the damage
from the inside when it hardens.
▷ Follow the instructions on using the tire re-
pair set found on the compressor and seal-
ant bottle.
▷ The use of a tire repair set can be ineffec-
tive if the tire puncture measures above ap-
prox. 0.16 in/4 mm.
▷ Do not remove foreign objects that have
penetrated the tire. Remove foreign objects
only when they are visibly protruding from
the tire.
▷ The compressor can be used to check the
tire inflation pressure.
