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 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.
After coming to a halt, the brake is released
automatically. Secure the vehicle against roll‐
ing.

The indicator lights in the instrument cluster
light up and the mark in the speedometer is set
to the current speed.
Cruise control can be used.
Switch off Deactivated or interrupted system
With deactivated or interrupted system
use your brakes, steering and moves as usual
to avoid the chance of an accident.◀
To switch off the system while standing, step
on brake pedal at the same time.
Press button on the steering wheel.▷If active: press twice.▷If interrupted: press once.
The displays go out. The stored desired speed
is deleted.
Interrupting Press button on the steering wheel.
If interrupting the system while stationary,
press on the brake pedal at the same time.
The system is automatically interrupted in the
following situations:
▷When the brakes are applied.▷When selector lever position D is disen‐
gaged.▷When DTC Dynamic Traction Control is
activated or DSC is deactivated.▷When DSC is actively controlling stability.▷When SPORT+ is activated with Driving
Dynamics Control.▷If the safety belt and the driver's door are
opened while the vehicle is standing still.▷If the system has not detected objects for
an extended period, e.g., on a road with
very little traffic without curb or shoulder
markings.▷If the detection range of the radar is dis‐
rupted, e.g., by dirt or heavy fog.
Maintaining, storing, and changing the
speed
Hints Adjusting the desired speedModify desired speed to road conditions
and be ready to brake at all times; otherwise,
there is the risk of an accident.◀
Differences in speed
Large differences in speed relative to
other vehicles cannot be compensated by the
system such as in the following situations:
▷When fast approaching a slowly moving
vehicle.▷When another vehicle suddenly swerves
into the wrong lane.▷When stationary objects are approached at
high speed.◀
Maintaining/storing the speed
Press button.
Or:
Press the rocker switch while the system is in‐
terrupted.
When the system is switched on, the current
speed is maintained and stored as the desired
speed.

Load
The maximum load is the sum of the weight of
the occupants and the cargo.
The greater the weight of the occupants, the
less cargo that can be transported.
Stowing cargo
▷Cover sharp edges and corners on the
cargo.▷Heavy cargo: stow as far forward as possi‐
ble, directly behind and at the bottom of
the rear passenger seat backrests.▷Very heavy cargo: when the rear seat is not
occupied, secure each of the outer safety
belts in the opposite buckle.
Securing cargo
Lashing eyes in the trunk
To secure the cargo there are four lashing
eyes in the cargo area.
Securing cargo
Securing cargo
Stow and secure the cargo as described;
otherwise it may present a danger to the occu‐
pants, e.g., during braking and evasive maneu‐
vers.◀▷Smaller and lighter items: secure with re‐
taining straps or with a cargo net or draw
straps.▷Larger and heavy objects: secure with
cargo straps.
Cargo straps, cargo netting, retaining straps or
draw straps on the lashing eyes in the trunk.

Damage from Velcro® fasteners
Open Velcro® fasteners on pants or
other articles of clothing can damage the seat
covers. Ensure that any Velcro® fasteners are
closed.◀
Caring for special components
Light-alloy wheels When cleaning the vehicle, use only neutral
wheel cleaners having a pH value from 5 to 9.
Do not use abrasive cleaning agents or steam
jets above 140 ℉/60 ℃. Follow the manufac‐
turer's instructions.
Aggressive, acidic or alkaline cleaning agents
can destroy the protective layer of adjacent
components, such as the brake disk.
Chrome surfaces Carefully clean components such as the radia‐
tor grille or door handles with an ample supply of water, possibly with shampoo added, partic‐
ularly when they have been exposed to road
salt.
Rubber components Aside from water, treat only with rubber
cleansers.
When cleaning rubber seals, do not use any
silicon-containing car care products in order to
avoid damage or noises.
Fine wood parts
Clean fine wood facing and fine wood compo‐
nents only with a moist rag. Then dry with a
soft cloth.
Plastic components These include:▷Imitation leather surfaces.▷Roofliner.▷Lamp lenses.▷Instrument cluster cover.▷Matt black spray-coated components.▷Painted parts in the interior.
Clean with a microfiber cloth.
Dampen cloth lightly with water.
Do not soak the roofliner.
No cleansers that contain alcohol or sol‐
vents
Do not use cleansers that contain alcohol or
solvents, such as lacquer thinners, heavy-duty
grease removers, fuel, or such; this could lead
to surface damage.◀
Safety belts
Dirty belt straps impede the reeling action and
thus have a negative impact on safety.
Chemical cleaning
Do not clean chemically; this can destroy
the webbing.◀
Use only a mild soapy solution, with the safety
belts clipped into their buckles.
Do not allow the reels to retract the safety
belts until they are dry.
Carpets and floor mats 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.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, e.g.◀
Floor mats can be removed from the car's inte‐
rior for cleaning.
