Aquaplaning If wate

ing occurring, even if:
R you are driving at low speeds
R the tyres have adequate tread depth
For this reason, drive in the following manner in the event of heavy rain or in conditions in which
aquaplaning can occur:
R lowery ours peed
R avoid tyre ruts
R avoid sudden steering movements
R brake carefully
Drivin gonflooded roads !
Bear in mind that vehicles travelling in front
or in the opposite direction create waves. This may cause the maximum permissibl ewater
depth to be exceeded. These notes must be observed under all cir-
cumstances. You could otherwise damage
the engine, the electronics or the transmis-
sion.
If you must drive on stretches of road on which
water has collected, please bear in mind that:
R in the case of standing water, the water level
must be no higher than the lower edge of the
vehicle body
R you should drive no faster than walking pace
Off-road fording !
Under no circumstances should you accel-
erate before entering the water. The bow
wave could cause water to enter and damage
the engine and neighbouring assemblies.
! Do not open any of the vehicle's doors while
fording. Otherwise, water could get into the
vehicle interior and damage the vehicle's
electronics and interior equipment.
i You may only drive through fresh water.
R Observe the safety notes (Y page 119) and
general notes (Y page 119) on driving off-
road
R Establish how deep the water is and the char-
acteristics of the body of water before fording
R Switch off automatic climate control
R Vehicles with auxiliary heating/ventila-
tion: switch the auxiliary heating/ventilation
off
R Shift the transfer case to the LOW RANGE

R Drive slowly and at aconstant speed through
the water
R Ensure that abow wave does not form as you
drive
R Do not stop and do not switch off the engine.
Water offers ahigh degree of resistance, the
ground is slippery and, in some cases, unsta- ble. Therefore, it is difficult and dangerous to pull awayinw ater

draws on the vehicle battery. After you have
heated or ventilated the vehicle amaximum of
two times, drive for alonger distance.
Only vehicles with auxiliary heating have this
function (Y page 89).
In the Heating Heating submenu, you can select a
stored departure time or change adeparture

The auxiliary heating timer function calculates
the switch-on time accordin gtothe outside
temperature so that the vehicle is preheated by the departure time. When the departure time isreached, the auxiliary heating continues to heat for afurther five minutes and then switches off.

WARNING
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel.W hen the engine is running,
components in the exhaust system may over-
heatu nnoticed. There is arisk of fire.
Never refue lwith petrol. Never add petrol to
diesel fuel.
! When refuelling, only use diesel fuel that
conforms to the European standard EN 590 or is of equivalent quality .Fuel that does not
conform to EN 590 can leadtoi ncreased wear
as wellasd amage to the engine and exhaust
system. !
Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not mix such fuels with diesel fuel and do
not use any special additives. Otherwise,
engine damage may occur.
! Vehiclesw
ith diesel particle filters: in
countries outside the EU, only use low sulphur
Euro diesel with asulphurc ontent of under
50 ppm. Otherwise, the emission control sys- tem could be damaged.
You will usually find information aboutt he fuel
quality on the pump. If you cannot find the label
on the petrol pump, ask the filling station staff.
Information on refuelling (Y page 109).
Low outside temperatures In winter months, diesel fuel with an improved
cold flow quality is available. In Europe, the
EN 590 standard defines various climate-
dependent temperature categories. Malfunc-
tions can be avoided by refuelling with diesel
fuel that corresponds to the climatic specifica-
tions outlined in EN 590. At unusually low out-
side temperatures, it is possible that the flow
characteristics of the diesel fuel could be insuf- ficient. Accordingly, diesel fuel from warmer
areas may not be suitablef or operation in colder
climatic conditions.
i Further information on country-specific fuel
properties and fuel types with low-tempera-
ture resistance can be obtained from oil com- panies, e.g. at filling stations. AdBlue
