tor warning lamp
comes on. G
WARNING
The tire pressure monitor indicates a rapid or severe loss of pres-
sure in at least one tire.
X Stop the vehicle without making any extreme steering maneu-
vers or braking suddenly. Pay attention to the traffic conditions
while doing so.
X Check the tires and correct the tire pressure. If a tire continues
to lose pressure, it must be replaced. Replace damaged tires
immediately.
The warning light will go out after the flat tire has been rectified
and you have been driving for a few minutes.

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 "Secur-
ing luggage/loads" (Y page 244) and "Load
distribution" (Y page 244) 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 ( Ypage 290).
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 244).
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 244).
Always observe the relevant country-spe-
cific legal requirements, laws and regula-
tions. Checks after loading
G
WARNING
Combustion engines emit poisonous exhaust
gases, such as carbon monoxide. If the sliding
door or rear door is open when the engine is
running, exhaust gases can enter the vehicle
interior, especially during the journey. There
is a risk of poisoning. Loading guidelines
243Transporting loads
Z
Always switch off the engine before opening
the sliding door or rear door. Never drive the
vehicle when the sliding door or rear door is
open.
X Securing loads: check that the load is
secure before every journey and at regular
intervals during a long journey, and correct
if necessary.
X Doors: close the sliding doors and rear
doors.
X Tire pressure: adjust the tire pressures
according to the vehicle load
(Y page 290).
X Driving style: adapt your driving style
according to the vehicle load. Load distribution
General notes
! Excessive loads on individual points of the
cargo floor or on the load surface impair
vehicle handling characteristics and could
cause damage to the floor covering.
The overall center of gravity of the load should
always be as low as possible, centered and
between the axles near the rear axle.
On Cargo Vans/Passenger Vans:
X Always transport loads in the cargo com-
partment.
X Always place the load against the backrests
of the rear bench seat.
X Move large and heavy loads as far towards
the front of the vehicle as possible against
the rear bench seat. Stow the load flush
with the rear bench seat.
X Always additionally secure the load with
suitable load-securing aids or tie downs. Observe the following notes:
R
Do not stack loads higher than the upper
edge of the backrests.
R Transport loads behind seats that are not
occupied.
R If the rear bench seat is not occupied, insert
the seat belts crosswise into the buckle of
the opposite seat belt. Securing loads
Important safety notes
G
WARNING
If you attach the tie-down incorrectly when
securing the load, the following may occur in
the event of abrupt changes in direction, brak-
ing maneuvers or an accident:
R the cargo tie-down rings may become
detached or the tie-down may tear if the
permissible load is exceeded
R the load may not be restrained.
This may cause the load to slip, tip over or be
tossed about, striking vehicle occupants.
There is a risk of an accident and injury.
Always tension the tie-downs in the proper
manner and only between the described
cargo tie-down rings. Always use tie-downs
designed specifically for the loads. G
WARNING
You may not transport anyone in the cargo
compartment or on the load surface. Never
let more people ride in the vehicle than there
are seat belts available. Make sure everyone
riding in the vehicle is correctly restrained
with a separate seat belt. Never use a seat
belt for more than one person at a time.
! Observe the information on the maximum
loading capacity of the individual cargo tie-
down points.
If you use several cargo tie-down points to
secure a load, you must always take the 244

Adding engine oil G
WARNING
If engine oil comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Make sure that engine oil is not spilled next
to the filler neck. Let the engine cool down
and thoroughly clean the engine oil off the
components before starting the engine.
! The alternator is located below the engine
oil filler neck. If engine oil spills onto the
alternator, there is a danger of alternator
damage. Be very careful when adding
engine oil. H
Environmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful
to the environment.
! Do not add too much oil. adding too much
engine oil can result in damage to the
engine or to the catalytic converter. Have
excess engine oil siphoned off.
! Do not use any additives in the engine oil.
This could damage the engine.

G
WARNING
The engine cooling system is pressurized, par-
ticularly when the engine is warm. When
opening the cap, you could be scalded by hot
coolant 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
painted surfaces. You could otherwise
damage the paintwork. Example: cap and coolant expansion tank
