your skin or clothing. Your health may be
damaged if:
\4you spill fuel onto your bare skin

\1Add coolant as far as the MAX mark.
\1Twist cap1 back on.
For coolant specifications, see "Service
products and capacities" (\2page 355).Environmental note
H
When adding oil, take care not to spill any.
No engine oil must be allowed to enter sew-
age systems, surface water, ground water or
soil.
You would otherwise be damaging the envi-
ronment.
Dispose of engine oil in an environmentally
responsible manner. Comply with the manu-
facturer’s instructions.Coolant
Warning
G
When opening the coolant expansion tank
there is a risk of scalding from hot coolant
spraying out. The cooling system and the
coolant expansion tank are pressurized
when the engine is at normal operating tem-
perature.
Wear gloves and eye protection. Only open
the coolant expansion tank when the cool-
ant temperature is less than 122 °F (50 °C).
N20.30-2063-31
Warning
G
Coolant contains glycol and is therefore tox-
ic. Do not swallow coolant. Consult a doctor
immediately if any coolant is swallowed.
Do not allow coolant to come into contact
with your skin, eyes or clothing. In the event
of contact with the eyes, rinse them thor-
oughly with clean water. Clean skin and
clothes immediately with soap and water.
Change out of soiled clothing without delay.

To avoid the risk of causing serious or fatal
injury, or damage to the vehicle, please bear
the following points in mind:
\4The jack is designed only to raise the ve-
hicle for a short time, for example while
a wheel is being changed.
It is not designed to enable work to be
carried out underneath the vehicle.

surface only.
\4Do not change wheels on uphill or down-
hill gradients under any circumstances.
\4Do not crawl under the vehicle if it is
only supported by the jack.
\4Make sure that no persons are present
in the vehicle when raising the vehicle.
