A recommendation to take a break is displayed
only once during an uninterrupted trip.
After a break, another recommendation to take
a break cannot be displayed until after approxi‐
mately 45 minutes.
System limits
The function may be limited in the following
situations, for instance, and will either output
an incorrect warning or no warning at all:▷When the clock is set incorrectly.▷When the vehicle speed is mainly below
about 43 mph/70 km/h.▷With a sporty driving style, such as during
rapid acceleration or when cornering fast.▷In active driving situations, such as when
changing lanes frequently.▷When the road surface is poor.▷In the event of strong side winds.
PreCrash
The concept With this system critical driving situations that
might result in an accident can be detected
above a speed of approx. 20 mph/30 km/h. In these situations, preventive measures are au‐
tomatically taken to minimize the risk of an ac‐
cident as much as possible.
Critical driving situations may include:
Emergency stop.
If the vehicle includes the front-end collision
warning or front-end collision warning with
braking feature, impending collisions with vehi‐
cles driving ahead or stopped in front of you
can also be detected within the system's
range.
Note
Personal responsibility
The system cannot possibly serve as a
substitute for the driver's personal judgment of
the traffic situation. The system may not al‐
ways detect critical situations reliably and in a
timely manner. Adapt speed to traffic situation
and drive alertly; otherwise, a risk to safety may
result.◀
Function
After the safety belt is buckled, the front belts
are automatically pretensioned once after the
vehicle is driven is away.
In critical driving situations, the following indi‐
vidual functions become active as needed:▷The front belts are automatically preten‐
sioned.▷Automatic closing of the windows.▷Automatic closing of the glass sunroof.▷For vehicles equipped with power backrest
adjustment: automatic positioning of the
backrest for the front passenger seat.
After a critical driving situation without an acci‐
dent, the front belts are loosened again. All
other systems can be restored to the desired
setting.
If the belt tension does not loosen automati‐
cally, stop the vehicle and unbuckle the belt
using the red button in the buckle. Fasten the
belt before continuing on your trip.
PostCrash
In the event of an accident, the system can
bring the car to a halt automatically without in‐
tervention by the driver in certain situations.
This can reduce the risk of a further collision
and the consequences thereof.
Depressing the brake pedal can cause the ve‐
hicle to brake harder. This interrupts automatic
braking. Destepping on the gas pedal also in‐ terrupts automatic braking.

Things to remember when drivingVehicle 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.
Breaking-in period
General information Moving parts need time to adjust to one an‐
other (break-in time).
The following instructions will help accomplish
a long vehicle life and good efficiency.
During break-in, do not use the Launch Con‐
trol, refer to page 75.
Engine, transmission, and axle drive Always obey the official speed limit.
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road
speed:▷For gasoline engine 4,500 rpm and
100 mph/160 km/h.
Avoid full load or kickdown under all circum‐
stances.
From 1,200 miles/2,000 km The engine and vehicle speed can gradually be
increased.
Tires
Tire traction is not optimal due to manufactur‐
ing circumstances when tires are brand-new;
they achieve their full traction potential after a
break-in time.
Drive conservatively for the first
200 miles/300 km.
Brake system
Brakes require an initial break-in period of ap‐
prox. 300 miles/500 km to achieve optimal per‐
formance between brake discs and brake
pads. Drive moderately during this break-in pe‐
riod.
Following part replacement
The same break-in procedures should be ob‐
served if any of the components above-men‐
tioned have to be renewed in the course of the
vehicle's operating life.
General driving notes
Closing the trunk lid Drive with the trunk lid closed
Only drive with the tailgate closed; other‐
wise, in the event of an accident or braking and
evasive maneuvers, passengers and other traf‐
fic may be injured, and the vehicle may be
damaged. In addition, exhaust fumes may en‐
ter the vehicle interior.◀
If driving with the tailgate open cannot be
avoided:▷Close all windows and the glass sunroof.▷Greatly increase the air flow from the vents.▷Drive moderately.
Hot exhaust system
Hot exhaust system
High temperatures are generated in the
exhaust system.

Saving fuelVehicle features and optionsThis 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.
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 cargoAdditional weight increases fuel consumption.
Remove attached parts
following use
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.
Close the windows and glasssunroof
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 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.
If necessary, observe the gear shift indicator of
the vehicle, refer to page 88.Seite 183Saving fuelDriving tips183

Vehicle batteryMaintenance
The battery is maintenance-free.
The added amount of acid is sufficient for the
service life of the battery.
Further information about the battery can be
obtained from your service center.
Battery replacement Use approved vehicle batteries only
Only use vehicle batteries that have been
approved for your vehicle by the manufacturer;
otherwise, the vehicle could be damaged and
systems or functions may not be fully availa‐
ble.◀
After a battery replacement, have the battery
registered on the vehicle by your service cen‐
ter to ensure that all comfort features are fully
available and that any Check Control mes‐
sages of these comfort features are no longer
displayed.
Charging the battery
Note Do not connect charging devices to the12 volt socket in the vehicle
Do not connect battery chargers to the fac‐
tory-installed 12 volt sockets in the vehicle as
this may damage the vehicle battery due to an
increased power consumption.◀
General information Make sure that the battery is always suffi‐
ciently charged to guarantee that the battery
remains usable for its full service life.
The battery may need to be charged in the fol‐
lowing cases:▷When making frequent short-distance
drives.▷If the vehicle is not used for prolonged pe‐
riods, longer than a month.
Starting aid terminals
In the vehicle, only charge the battery via the
starting aid terminals, refer to page 225, in the
engine compartment with the engine off.
Power failure After a temporary power loss, some equipment
needs to be newly initialized or individual set‐
tings updated, e.g.:
▷Seat, mirror, and steering wheel memory:
store the positions again.▷Time: update.▷Date: update.▷Glass sunroof: initialize the system, refer to
page 48.
Disposing of old batteries
Have old batteries disposed of by your
service center or bring them to a recy‐
cling center.
Maintain the battery in an upright position for
transport and storage. Secure the battery so
that it does not tip over during transport.
Fuses Hints Replacing fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a substi‐
tute of another color or amperage rating; this
could lead to a circuit overload, ultimately re‐
sulting in a fire in the vehicle.◀
Plastic tweezers and information on the fuse
types and locations are stored in the fuse box
in the cargo area.

Car washes
General information
Regularly remove foreign objects such as
leaves in the area below the windshield when
the hood is raised.
Wash your vehicle frequently, particularly in
winter. Intense soiling and road salt can dam‐
age the vehicle.
Hints Steam jets or high-pressure washers
When using steam jets or high-pressure
washers, hold them a sufficient distance away
and use a maximum temperature of
140 ℉/60 ℃.
If the vehicle has a glass sunroof, ensure that a
distance of at least 31.5 inches/80 cm is main‐
tained. Holding them too close or using exces‐
sively high pressures or temperatures can
cause damage or preliminary damage that may
then lead to long-term damage.
Follow the user's manual for the high-pressure
washer.◀
Cleaning sensors/cameras with high-
pressure washers
When using high-pressure washers, do not
spray the exterior sensors and cameras, e.g.,
Park Distance Control, for extended periods oftime and only from a distance of at least
12 in/30 cm.◀
Automatic car washes
Hints Do not use high pressure washing sys‐
tems
With washing systems operating at high pres‐
sures and nozzle positions close to the win‐
dows, drops of water can penetrate.◀
Note the following:▷Give preference to cloth car washes or
those that use soft brushes in order to
avoid paint damage.▷Make sure that the wheels and tires are not
damaged by the transport mechanisms.▷Fold in the exterior mirrors; otherwise, they
may be damaged, depending on the width
of the vehicle.▷Deactivate the rain sensor, refer to
page 70, to avoid unintentional wiper acti‐
vation.▷In some cases, an unintentional alarm can
be triggered by the interior motion sensor
of the alarm system. Follow the instruc‐
tions on avoiding an unintentional alarm,
refer to page 45.
Guide rails in car washes
Avoid car washes with guide rails higher
than 4 in/10 cm; otherwise, the vehicle body
could be damaged.◀
