Always observe the operating instructions of
the respective manufacturer when using suit- able load securing aids or tie downs. In par-
ticular, the information on service life.
Load securing aids and tie downs may not be used, for example, if:
R identification marks are missing or illegible
R there are yarn breakages, damage to bear-
ing seams or other signs of tearing
R there are signs of shearing, deformation,
pinching or other damage
R there is damage to clamping or connecting
elements
Such load securing aids and tie downs are
worn; they should not be used and must be
replaced. If you use load securing aids or tie
downs which are worn, the load may not be
sufficiently secured and could cause damage
to property.
After an accident, the following must be
checked at a specialist workshop:
R Cargo compartment floor
R Load surface
R Cargo tie-down rings
R Tie downs
Otherwise, the load may not be correctly
secured the next time anything is stowed.
Even if you follow all loading guidelines, the
load increases the risk of injury in the event of an accident. Observe the tips in the "Securing
luggage/loads" (Y page 242) and "Load dis-
tribution" (Y page 242) sections. Before loading
! The anti-slip mats cannot be used for
securing goods and must be replaced when
they show signs of:
R Permanent deformation and crushing
R Crack formation
R Cuts X
Tire pressure: check the tire pressure and
correct if necessary (Y page 288).
X Cargo compartment floor: clean the
cargo compartment floor.
The cargo compartment floor must be free
from oil and dust, dry and swept clean to
prevent the load from slipping.
X Place non-slip mats (anti-slip mats) on the
cargo compartment floor if necessary. During loading
! On passenger van versions with maxi-
mum seating layout, the permissible rear
axle load would be exceeded if the full pay-
load were to be loaded in the cargo com-
partment.
X Observe the gross axle weight rating and
permissible gross vehicle weight for your
vehicle.
Take into account that your vehicle's curb
weight is increased if accessories or
optional equipment are installed. The max-
imum payload is thus reduced.
X Observe the notes on load distribution
(Y page 242).
The overall center of gravity of the load
should always be as low as possible, cen-
tered and between the axles near the rear
axle.
X Secure the load (Y page 242).
Observe the legal requirements of the
country in which you are currently driving. Checks after loading

WARNING
The engine cooling system is pressurized, par- ticularly when the engine is warm. When
opening the cap, you could be scalded by hotcoolant spraying out. There is a risk of injury.
Let the engine cool down before opening the
cap. Wear eye and hand protection when
opening the cap. Open the cap slowly half a
turn to allow pressure to escape.
Only check the coolant level and/or fill the
coolant if the vehicle is on a level surface and the engine has cooled down. The coolant tem-
perature must be below 122 ‡ (50 †).
! Check the engine cooling and heating sys-
tem regularly for leaks.
If a large quantity of coolant is lost, have the
cause traced and rectified at a qualified
specialist workshop. G
WARNING
Coolant contains glycol and is therefore toxic. Do not swallow the coolant. See a doctor
immediately if you swallow coolant.
Make sure that coolant does not come into
contact with skin, eyes or clothing. In case of
contact with eyes, rinse immediately with
plenty of clean water. Clean affected areas of skin and clothing with soap and water imme-
diately. Change any affected clothing imme-
diately. G
WARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
! Take care not to spill any coolant on pain-
ted surfaces. You could otherwise damage
the paintwork. Example: cap and coolant expansion tank
Checking the coolant level
X Stop your vehicle as far away from traffic as
possible on level ground.
X Switch off the engine.
X Secure the vehicle to prevent it from rolling
away.
X Open the hood (Y page 248).
X Slowly turn cap 0043half a turn counter-
clockwise to allow excess pressure to
escape.
X Turn cap 0043further and remove it.
X Check the coolant level.
If the coolant reaches the maximum mark
on coolant expansion tank 0044, there is
enough coolant in coolant expansion
