This section only applies to vehicles with all-
wheel drive (4MATIC). The front and rear
axles are constantly driven.
! Performance tests may only be carried
out on a two-axle roller dynamometer. Oth-
erwise, the braking system or the transfer
case could be damaged. Contact a qualified
specialist workshop for more information
on performance tests.
! Since ESP ®
engages automatically, the
ignition must be switched off (the key or
Start/Stop button must be in position 0or

the transmission may be damaged. Refuelling
Important safety notes
G
WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refuelling. G
WARNING
Fuels are poisonous and hazardous to health. There is a danger of injury.
Do not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel Refuelling

with the vehicle parked on a level surface.
Fluctuations in capacity will thus be avoi-
ded. Filling a vehicle standing on an uneven surface is not permitted. There is a danger
of overfilling, which can cause damage to
BlueTEC exhaust gas aftertreatment com-
ponents.
! Surfaces which have come into contact
with AdBlue ®
while refilling should be
rinsed immediately with water, or remove
AdBlue ®
with a moist cloth and cold water.
If AdBlue ®
has already crystallised, use a
sponge and cold water to clean the area.
AdBlue ®
residue crystallises after a certain
amount of time and soils the affected sur-
faces.
! AdBlue ®
is not a fuel additive and must
not be added to the fuel tank. If AdBlue ®
is
added to the fuel tank, this can lead to
engine damage.
Have the AdBlue ®
tank refilled at a qualified
specialist workshop. However, you can also
top up the AdBlue ®
tank:
R at a filling station with an AdBlue ®
filling
pump
R with AdBlue ®
refill bottles
R with an AdBlue ®
refill canister
When the pump nozzle switches off automat- ically during filling at a filling pump, the
AdBlue ®
tank has been completely filled. Do
not fill the AdBlue ®
tank any further. AdBlue ®
may leak out.
To avoid transporting already opened refill
containers in the vehicle, completely empty
refill bottles or canisters when filling the
AdBlue ®
tank, if possible.
Further information on AdBlue ®
(Y page 484). Opening the AdBlue
®
filler cap X

RefuellingDriving and parking
Energy consumption and electrical
range The maximum electrical range is generally
reduced by:
R high and low outside temperatures
R operating the climate control system
R switching on consumers
The battery's physical characteristics are
such, that leaving the vehicle parked for long
periods at low outdoor temperatures without charging it can lead to:
R a reduction in battery performance
R longer charge times
Notes on battery care Avoid storing or transporting the vehicle at
excessively high or low temperatures over a
long period.
If you park the vehicle and leave it stationary for long periods:
R check the charge status of the high-voltage
battery more often
R connect the vehicle to a power supply
This prevents self-discharge and damage to
the high-voltage battery.
Terms of use Please note the information on exceptions
and limitations in the warranty documenta-
tion and in the Service Booklet.
Handling the charging cable and charg- ing cable controls Do not leave the charging cable controls
(Y page 213) hanging loose from a mains
socket. Otherwise, this could result in a poor contact with the mains socket and malfunc-
tions when charging the vehicle. To ensure that the brackets within the charg-
ing cable controls are not subjected to incor-
rect loads, observe the following:
R never lift or carry the controls by the charg-
ing cable connector or the mains plug
R to transport the charging cable, the coiled
part can be:
- wrapped around the controls or
- secured to the housing of the controls
Heat generated by the charging cable
and charging cable connector Observe the "Important safety notes"
(Y page 210).
During the charging process, the charging
cable and charging cable connector may heat
up.
The charging cable and charging cable con-
nector will only heat up within the permissible limiting values, provided that:
R the mains power supply and the charging
cable are not damaged
R the instructions for handling the charging
cable and controls on the charging cable
are observed
If the charging cable or plug get too hot, have the mains power supply checked.
Protection against overvoltage !
Voltage surges in the mains supply can
damage the vehicle. The vehicle is there-
fore equipped with a device which protects
it from voltage surges in the mains supply.
This device may be triggered during severe
thunderstorms, for example, and may lead
to the building's fuse being tripped and an
interruption in the power supply. These
functions protect the vehicle. After the
building fuse is switched on again, the
charging process resumes automatically.
Following an interruption in the power sup-
ply or tripping of the building's fuse, it may take up to 10 minutes for charging to
resume automatically. 212
Charging the high-voltage battery (PLUG-IN HYBRID vehicles)Driving and parking
sideways, tip and overturn. There is a risk of
an accident.
When driving up an incline, drive into the line of fall (upwards or downwards in a straight
line) and do not turn. G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is a risk of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
! There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
kerb or an unpaved road
R you drive too fast over an obstacle, e.g. a
kerb or a pothole in the road
R a heavy object strikes the underbody or
parts of the chassis
In situations like this, the body, the under-
body, chassis parts, wheels or tyres could
be damaged without the damage being visi-
ble. Components damaged in this way can
unexpectedly fail or, in the case of an acci-
dent, no longer withstand the strain they
are designed for.
If the underbody panelling is damaged,
combustible materials such as leaves,
grass or twigs can gather between the
underbody and the underbody panelling. If
these materials come in contact with hot
parts of the exhaust system, they can catch fire.
In such situations, have the vehicle
checked and repaired immediately at a
qualified specialist workshop. If, upon con-
tinuing your journey, you notice that driving
safety is impaired, pull over and stop the
vehicle immediately, paying attention to road and traffic conditions. In such cases,
consult a qualified specialist workshop.
The vehicle is only designed for easily nego-
tiable off-road terrain and poor road surfaces. When driving off-road, substances such as
sand, mud and water or water mixed with oil
may get into the brakes. This may lead to a
reduction in braking performance or total
brake failure as a result of increased wear.
The braking characteristics will vary depend-
ing on the substances that get into the
brakes. Clean the brakes after driving off-
road. If you notice grinding noises or a reduc-
tion in braking performance, have the brake
system checked at a qualified specialist work- shop immediately. Adapt your driving style to
the altered braking characteristics.
Driving off-road increases the possibility of
damage to the vehicle, which may cause
assemblies or systems to fail. Adapt your
driving style to the conditions of the terrain.
Drive carefully. Have vehicle damage rectified immediately at a qualified specialist work-
shop.
Do not shift into transmission position N
when driving off-road. You could lose control
of the vehicle if you attempt to brake the
vehicle using the service brake. If the gradient
is too steep for your vehicle, back up in
reverse gear.
