DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, for example in
enclosed spaces or if the vehicle gets stuck in
snow. There is a risk of fatal injury.
Switch the auxiliary heating off in enclosed
spaces without extraction systems, e.g. in
garages. If the vehicle is stuck in snow and
you have to leave the auxiliary heating run-
ning, keep the exhaust pipe and the area
around the vehicle free of snow. To ensure an adequate supply of fresh air, open a window
on the side of the vehicle that is not facing into
the wind. G
WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot, e.g. the exhaust system.
Flammable materials such as leaves, grass or
twigs may ignite if they come into contact
with:
R hot parts of the exhaust system
R the exhaust gas itself
There is a risk of fire. When the auxiliary heating is switched on,
make sure that:
R no flammable materials come into contact
with hot vehicle components
R the exhaust gas can escape from the
exhaust pipe unhindered
R the exhaust gas does not come into contact
with flammable materials.
! Turn on the auxiliary heating at least once
a month for approximately 10 minutes. The
auxiliary heating could otherwise be dam-
aged.
! Make sure that the flow of hot air is not
blocked. The auxiliary heating will other-
wise overheat and switch off.
Your vehicle may be equipped with either an
auxiliary hot-water heater or an auxiliary
warm-air heater. Adjustment and operation of the:
R hot-water auxiliary heater is done via the
on-board computer and with the auxiliary
heating button in the control panel
(Y page 123) or with the remote control
(Y page 125).
R auxiliary warm-air heater is done via the
timer above the overhead control panel
(Y page 127).
The auxiliary heating works independently of
the engine and supplements the climate con- trol system in the vehicle. The auxiliary heat-
ing heats the air in the vehicle interior to the
temperature set.
If your vehicle is equipped with a hot-water
auxiliary heater, the auxiliary heating also
keeps the coolant warm. This way, the load on
the engine is minimized and fuel is saved.
The heater booster function (Y page 130) of
the auxiliary heating supports the climate
control system when the engine is running
and the outside temperature is low.
You can use the auxiliary heating at an out-
side temperature of up to 39 ‡ (4 †). At an
outside temperature above 39 ‡ (4 †) the 122

RefuelingDriving and pa
rking

You must depress the brake pedal more
firmly. Maintain a longer distance to the vehi- cle in front.
While paying attention to the traffic condi-
tions, you should brake the vehicle firmly
after driving on a wet road surface or through
a car wash. This heats the brake discs, so that they dry more quickly, which protects them
against corrosion.
Limited braking performance on salt-
treated roads When driving on salted roads, salt may start
to build up on the brake disks and brake pads.
This can increase braking distances consid-
erably.
Maintain a greater distance to the vehicle in
front.
To remove any build up of salt that may have
formed:
X Apply the brakes at the start of the journey,
occasionally during journey and at the end
of the journey. Make sure that you do not
endanger other road users when doing so.
Parking brake G
WARNING
If you must brake the vehicle with the parking brake, the braking distance is considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the vehi- cle when the service brake is faulty. Do not
apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again.
When driving on wet roads or dirt-covered
surfaces, road salt and/or dirt may get into
the parking brake. This causes corrosion and a reduction of braking force.
In order to prevent this, drive with the parking
brake lightly applied from time to time. When
doing so, drive for a distance of approximately 110 yds (100 m) at a maximum speed of
12 mph (20 km/h).
The brake lamps are not illuminated when you
brake the vehicle using the parking brake. Driving in wet conditions
Hydroplaning G
WARNING
There is a danger of hydroplaning occurring,
even if you are driving slowly and your tires
have sufficient tread depth, depending on the depth of water on the road. There is a risk of
an accident.
For this reason, avoid tire ruts and brake care- fully.
Therefore, in heavy rain or other conditions in which hydroplaning can occur, drive as fol-
lows:
R reduce your speed
R avoid tire ruts
R apply the brakes with care
Driving on flooded roads !
Do not drive through flooded areas.
Check the depth of any water before driving
through it. Drive slowly through standing
water. Otherwise, water may enter the
vehicle interior or the engine compartment.
This can damage the electronic compo-
nents in the engine or the automatic trans- mission. Water can also be drawn in by the engine's air suction nozzles and this can
cause engine damage.
If you have to drive on stretches of road on
which water has collected, please bear in
mind that:
R the water level of standing water should not
be above the lower edge of the front
bumper
R do not drive faster than walking speed Driving tips

Mobile phoneStowing and features

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
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

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 correctif necessary.
X Doors: close the sliding doors and rear
doors.
X Tire pressure: adjust the tire pressures
according to the vehicle load (Y page 288).
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 areseat belts available. Make sure everyone rid-
ing 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.
