▷Drive moderately.
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 while driving, while in idle po‐
sition mode, or when parked. Such contact
could lead to a fire, resulting in an increased
risk of serious personal injury as well as prop‐
erty damage.
Do not touch hot exhaust pipes; otherwise,
there is a danger of getting burned.◀
Mobile communication devices in the
vehicle
Mobile communication devices in the ve‐
hicle
It is not recommended to use mobile phones,
such as mobile phones, in the vehicle interior
without a direct connection to an external aer‐
ial. Otherwise, the vehicle's electronics and
mobile communication devices can interfere
with each other. In addition, there is no assur‐
ance that the radiation generated during trans‐
mission will be conducted away from the vehi‐
cle interior.◀
Hydroplaning Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent 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.
Driving through water Observe water level and speed
Do not exceed the maximum water level
and maximum speed; otherwise, the vehicle's
engine, the electrical systems and the trans‐
mission may be damaged.◀
Drive though 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
3 mph/5 km/h.
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 needed.
Steering is still responsive. You can still avoid
any obstacles with a minimum of steering ef‐
fort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
In certain braking situations, the perforated
brake discs can cause functional problems.
However, this has no effect on the perform‐
ance and operational reliability of the brake.
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 pedal area; 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 attached to
floor.Seite 157Things to remember when drivingDriving tips157

LoadingVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Hints Overloading the vehicle
To avoid exceeding the approved ca‐
pacity of the tires, never overload the vehicle.
Overloading can lead to overheating and in‐
creases the rate at which damage develops in‐
side the tires. This could result in a sudden
loss of tire inflation pressure.◀
No fluids in the cargo area
Make sure that fluids do not leak into the
cargo area; otherwise, the vehicle may be dam‐
aged.◀
Heavy and hard objects
Do not stow any heavy and hard objects
in the car's interior without securing them; oth‐
erwise, they may present a danger to occu‐
pants, e.g., during braking and evasive maneu‐
vers.◀
Determining the load limit1.Locate the following statement on your ve‐
hicle’s placard:▷The combined weight of occupants
and cargo should never exceed XXX kg
or YYY lbs. Otherwise, damage to thevehicle and unstable driving situations
may result.2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.3.Subtract the combined weight of the driver
and passengers from XXX kilograms or
YYY pounds.4.The resulting figure equals the available
amount of cargo and luggage load ca‐
pacity.
For example, if the YYY amount equals
1,000 lbs and there will be four 150 lbs
passengers in your vehicle, the amount of
available cargo and luggage load capacity
is 400 lbs: 1,000 lbs minus 600 lbs =
400 lbs.5.Determine the combined weight of lug‐
gage and cargo being loaded on the vehi‐
cle. That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.Seite 159LoadingDriving tips159

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.
Carrying out certain measures, such as a mod‐
erate driving style and regular maintenance,
can influence fuel consumption and the envi‐
ronmental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts
following use
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.
Closing the windows Open windows increase air resistance and
therefore lead to greater fuel consumption.Tires
General information
Tires can affect fuel consumption in various
ways, e.g., tire size may influence fuel con‐
sumption.
Check the tire inflation pressure
regularly
Check and, if needed, correct the tire inflation
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 quickest way of warming the cold
engine up to 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 proactively reduces fuel
consumption.
Avoid high engine speeds
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Use 1st gear to get the vehicle moving. Start‐
ing with the 2nd gear, accelerate rapidly. WhenSeite 161Saving fuelDriving tips161

Tire inflation pressure Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:▷The service life of the tires.▷Road safety.▷Driving comfort.
Checking the tire inflation pressure
Check the tire inflation pressure regularly
Regularly check the tire inflation pres‐
sure, and correct it as needed: at least twice a
month and before a long trip. If you fail to ob‐
serve this precaution, you may be driving on
tires with incorrect tire pressures, a condition
that may not only compromise your vehicle's
driving stability, but also lead to tire damage
and the risk of an accident.◀
Tires have a natural, consistent loss of tire in‐
flation pressure.
Tires heat up while driving, and the tire infla‐
tion pressure increases along with the tire's
temperature. The tire inflation pressure speci‐
fications relate to cold tires or tires with the
ambient temperature.
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been parked for at least 2 hours.
The displays of inflation devices may under-
read by up to 1.45 psi/0.1 bar.
For Flat Tire Monitor: after correcting the tire
inflation pressure, reinitialize the Flat Tire
Monitor.
For Tire Pressure Monitor: after correcting the
tire inflation pressure, reset the Tire Pressure
Monitor.
Tire inflation pressure specifications
The tire inflation pressure table, refer to
page 175, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. Tire inflation pressure
specifications apply to approved tire sizes and
recommended tire brands. This information
can be obtained from your service center.
To identify the correct tire inflation pressure,
please note the following:▷Tire sizes of your vehicle.▷Maximum permitted driving speed.
Tire inflation pressures up to
100 mph/160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure
values in the tire inflation pressure table, refer
to page 175, and adjust as necessary.

0115: tire age
Tires with DOT codes meet the guidelines of
the U.S. Department of Transportation.
Tire age DOT … 0115: the tire was manufactured in the
1st week of 2015.
Recommendation
Regardless of wear and tear, replace tires at
least every 6 years.
Uniform Tire Quality Grading Quality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section width.
For example: Treadwear 200; Traction AA;
Temperature A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to Fed‐
eral Safety Requirements in addition to these
grades.
TreadwearThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov‐
ernment test course. For example, a tire graded 150 would wear one and one-half, 1 g,
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and may depart signifi‐
cantly from the norm due to variations in driv‐
ing habits, service practices and differences in
road characteristics and climate.Traction
The traction grades, from highest to lowest,
are AA, A, B, and C.
Those grades represent the tire's ability to
stop on wet pavement as measured under
controlled conditions on specified government
test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction tests,
and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the ma‐
terial of the tire to degenerate and reduce tire
life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds
to a level of performance which all passenger
car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades Band
A represent higher levels of performance on
the laboratory test wheel than the minimum re‐
quired by law.
Temperature grade for this tire
The temperature grade for this tire is es‐
tablished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
If necessary, have the vehicle towed.◀
RSC – Run-flat tires
Run-flat tires, refer to page 182, are labeled
with a circular symbol containing the letters
