Hot exhaust systemHot exhaust system
High temperatures are generated in the
exhaust system.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that flammable materials, e. g. hay, leaves,
grass, etc. do not come in contact with the hot
exhaust system during driving, while in idle po‐
sition mode, or when parked. Such contact
could lead to a fire, and with it the risk of seri‐
ous personal injury as well as property dam‐
age.
Do not touch hot exhaust pipes; otherwise,
there is the danger of getting burned.◀
Diesel particulate filter The diesel particulate filter collects soot parti‐
cles and burns them periodically at high tem‐
peratures.
During the cleaning time of several minutes,
the following may occur:▷Temporarily, the engine may run less
smoothly.▷Noises and a slight amount of smoke com‐
ing from the exhaust until shortly after the
engine is shut down.▷A somewhat higher engine speed is neces‐
sary to achieve the accustomed perform‐
ance.
Mobile communication devices in the
vehicle
Mobile communication devices in the ve‐
hicle
It is advised that you do not use mobile com‐
munication devices, e.g., mobile phones, in‐
side the vehicle without connecting them di‐
rectly to the external antenna. Otherwise, the
vehicle electronics and mobile communication
devices can interfere with each other. In addi‐
tion, there is no assurance that the radiation
generated during transmission will be dis‐
charged from the vehicle interior.◀
Hydroplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.
Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent hydroplaning.◀
Driving through water Drive through calm water only and only if it is
not deeper than. 9.8 inches/25 cm and at this
height, no faster than walking speed, up to
6 mph/10 km/h.
Adhere to water depth and speed limita‐
tions
Do not exceed this water depth and walking
speed; otherwise, the vehicle's engine, the
electrical systems and the transmission may
be damaged.◀
Braking safely
Your vehicle is equipped with ABS as a stand‐
ard feature.
Applying the brakes fully is the most effective
way of braking in situations when this is neces‐
sary.
The vehicle maintains steering responsive‐
ness. You can still avoid any obstacles with a
minimum of steering effort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.Seite 167Things to remember when drivingDriving tips167

Objects within the range of movement
of the pedals
No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving and create the risk of an
accident.
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved
for the vehicle and can be properly fixed in
place.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, for example.◀
Driving in wet conditions When roads are wet coated with road salt or
there is heavy rain, briefly exert gentle pres‐
sure on the brake pedal every few miles.
Ensure that this action does not endanger
other road users.
The heat generated in this process helps dry
the brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills
Drive long or steep downhill gradients in the
gear in which the least braking is required.
Otherwise, the brake system may overheat, re‐
sulting in a reduction in the brake system effi‐
ciency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if necessary.
Avoid load on the brakes
Avoid placing excessive load on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brake wear
and possibly even brake failure.◀Do not drive in neutral
Do not drive in neutral or with the engine
stopped, as doing so disables engine braking.
In addition, steering and brake assist are un‐
available with the engine stopped.◀
Brake disc corrosion The corrosion on the brake discs and the con‐
tamination on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops that exits under‐
neath the vehicle.
Traces of water under the vehicle like this are
normal.

Saving fuelVehicle equipmentAll standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
General information Your vehicle contains advanced technology for
the reduction of fuel consumption and emis‐
sions.
Fuel consumption depends on a number of dif‐
ferent factors.
The implementation of certain measures, driv‐
ing style and regular maintenance can have an
influence on fuel consumption and on the envi‐
ronmental impact.
Remove unnecessary cargoAdditional weight increases fuel consumption.
Remove attached parts
following use
Remove auxiliary mirrors, roof or rear luggage
racks which are no longer required following
use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.Close the windows and glass
sunroof
Driving with the glass sunroof and windows
open results in increased air resistance and
thereby reduces the range.
Tires
General information Tires can affect fuel consumption values in
various ways, for instance fuel consumption
can be influenced by the size of the tires.
Check the tire inflation pressure
regularly
Check and, if necessary, correct the tire infla‐
tion pressure at least twice a month and before
starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away immediately
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate engine speeds.
This is the fastest way for the cold engine to
reach its operating temperature.
Look well ahead when
driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐
cle driving ahead of you.
Driving smoothly and looking ahead reduces
fuel consumption.Seite 172Driving tipsSaving fuel172
