iCanada only:
If the wind shield wiper s areswitched on and
you stop the veh icle, the windshield wiper
speed isreduced. For example, ifyou have
selected level IIand stop the veh icle,wipin g
continues with intermittent wipe whilethe
veh icle is stationary. Ifintermittent wipe is
selected, the intervals become longer.
Vehicles with a rain and light sensor: you
can use level Ias the universal setting. The
rain and light sensor sets the appropriate wip-
ing frequency automatically, according to the
intensity of the rain. When you stop the veh i-
cle, leve lsIII and IIare swit ched down to
level Iautomatically.
The wind shield wiper will return to the original
level when you drive faster than 5 mph
(8 km/h).
You can adjust the sensitivit y of the rain and
light sensor using the on-board computer
(
Ypage 170).
In formation on checking the washer fluid level
can befound inthe "Maintenance and care"
section (
Ypage 220).

Replacing the wiper blades
GWARNING
If the wind shield wipers begin to move while
you are changing the wiperblades, you could
be trapped by the wiper arm. There isa risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
!Never open the hood if a windshield wiper
arm has been folded away from the wind-
shield.
Never fold a windshield wiper armwithout a
wiper blade back onto the windshield/rear
wind ow.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the
windshield wiper arm without a wiperblade
and itfalls onto the windshield, the windshield
may be damaged by the force of the impact.
We recommend that you have the wiper
blades replaced at a qualified specialist work-
shop.
!Only hold the wiperblade by the wiperarm.
You could otherwise damage the wiper rub-
ber.
The wind shield will no longerbe wipedproperly
if the wiper blades are worn. Replace the wiper
blades twice a year, ideally in spring and fall.

Problems with the fuel and fuel tank
If your vehicle is losing fuel, the fuel lines or thefuel tank are defective.
XTurn the SmartKey immediately to position 0
in the ignition lock and remove it.
XDo not restart the engine under any circum-
stances.
XConsult a qualified specialist workshop.
If the fuel tank has been run dry, after refueling
carry out the following steps:
XBefore starting the engine: switch on the igni-
tion three or four times.
XTurn the SmartKey to position 2in the ignition
lock (Ypage 117).
The % preglow indicator lamp in the instru-
ment cluster lights up briefly.
XOnce the %preglow indicator lamp goes
out, turn the SmartKey to position 3in the
ignition lock and release it as soon as the
engine is running.
You can start the diesel engine without preglow
when the engine is warm.
Diesel Exhaust Fluid (DEF)
Important safety notes
!Only use DEF in accordance with
ISO 22241. Never mix DEF with additives or
thin it with tap water. The exhaust gas after-
treatment may otherwise be damaged.
Observe the MB Specifications for Service
Products, Sheet 352.0.
Damage that results from the use of additives
or tap water leads to the loss of the New
Vehicle Limited Warranty.
!If DEF comes into contact with a painted or
aluminum surface, wash the surface off
immediately with plenty of water.
!DEF is not a diesel additive and must not be
mixed with fuel in the tank. Even small
amounts of DEF can cause engine damage.
Damage that results from the blending of DEF
will not be covered by the New Vehicle Limi-
ted Warranty.
iIf the outside temperature is below 12 ‡
(Ò11 †) it may be difficult to top up. If the DEF
is frozen and there is an active warning indi- cator, topping up may not be possible. Park
the vehicle in a warm place, e.g. in a garage,
until the DEF has become liquid again. Top-
ping up is then possible again. Alternatively,
have the DEF tank refilled at a qualified spe-
cialist workshop.
iIf you add DEF at temperatures below 12 ‡
(Ò11 †) it is possible that the level is not
shown correctly due to the frozen DEF.
Drive for at least 20 minutes (heating phase in
the tank activated) and then stop the vehicle
for at least 30 seconds. The level is then
shown correctly.
You will find further information on DEF in the
"Service products" section (
Ypage 273).

Parking
Important safety notes
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.
Park the vehicle so that no flammable mate-
rials come into contact with parts of the vehi-
cle which are hot. Take particular care not to
park on dry grassland or harvested grain
fields.
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
!A moving vehicle can lead to damage to the
vehicle or damage to the drive train.
!When the vehicle is parked, always remove
the key to prevent the battery from becoming
discharged.
On vehicles with a battery isolating switch,
switch off the power supply if the vehicle is to
be out of use for a longer period of time.
