Change into a lower gear in good time on long
and steep downhill gradients. This is especially
impo rtant if the veh icle is laden. By doin g so, you
will make use of the braking effect of the engine.
This relieves the load on the brake system and
prevents the brakes from overheating and wear-
ing too quic kly.
If Distance Pilot DI ST RONIC detects that there is
a risk of a co llisio n, you will be warned visually
and acoustically. Without your intervention, Dis-
tance Pilot DISTRONIC cannot prevent a co lli-
sion. An intermittent warning tone will then
sound and the dist ance warning lamp will light
up in the instrument cluster. Brake immediately
in order to increase the dist ance to the veh icle in
front or take evasive action pro vide d it is safe to
do so.
Distance Pilot DI ST RONIC operates in the range
between 0 mph (0 km/h) and 120 mph
(200 km/h).
Do not use Distance Pilot DI ST RONIC while driv -
ing on roads with steep gradients.
Sin ce Distance Pilot DI ST RONIC transmits radar
waves, it can resemble the radar detectors of
the respon sible authorities. You can refer to the
relevant chapter in the Operator's Manual if
questions are asked about this.

Important safety notes
G WARNING
Distance Pilot DI ST RONIC does not react to: R
people or animals R
stationary objects on the road, e.g. st oppe d
or parked vehicles R
oncoming vehicles and crossing traffic
As a result, Distance Pilot DI ST RONIC may
neither give warnings nor intervene in such
situations. There is a risk of an accident.
Alwa ys pay careful attention to the traff ic sit-
uation and be ready to brake.
G WARNING
Distance Pilot DI ST RONIC cannot always
clearly identify other road users and co mple x
traff ic situations.
In such cases, Distance Pilot DI ST RONIC may:R
give an unnecessary warning and then
brake the vehicle R
neither give a warning nor intervene R
accelerate or brake unexpect edly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, especially if Distance Pilot DISTRONIC
warns you.
G WARNING
Distance Pilot DI ST RONIC brakes your vehicle
with up to 50% of the maximum poss ible
deceleration. If this deceleration is not suffi-
cient, Distance Pilot DI ST RONIC alerts you
wit h a visual and acoustic warning. There is a
risk of an accident.
Apply the brakes yourself in these situations
and try to take evasive action.
! When Distance Pilot DI ST RONIC or the
HOLD function are activated, the vehicle
brakes automatically in certain situations.Driving systems 171

AIR BODY CONTROL
General notes AIR BODY CONTROL is an air suspension system
with variable damping for improved driving com-
fort. All-round level control ensures the best
possible suspension and constant ground clear-
ance, even with a laden vehicle. When you drive
fast, the vehicle is lowered automatically to
improve driving safety and to reduce fuel con-
sumption. There is also the option to manually
adjust the vehicle level.
AIR BODY CONTROL consists of: R
air suspension system with variable spring
rate R
automatic level control R
speed-dependent lowering to reduce fuel
consumption R

Important safety notes
G WARNING
Lane Keeping Assist cannot always clearly
detect lane markings.
In such cases, Lane Keeping Assist can: R
give an unnecessary warning R
not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Lane Keeping Assist alerts you.
G WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
Lane Keeping Assist can neither reduce the risk
of an accident if you fail to adapt your driving
style nor override the laws of physics. Lane
Keeping Assist cannot take into account the
road, traffic and weather conditions. Lane Keep-
ing Assist is merely an aid. You are responsible
for the distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for stay-
ing in your lane.
The Lane Keeping Assist does not keep the vehi-
cle in the lane.
The system may be impaired or may not function
if: R
there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray R
there is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet) R
the windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera R
there are no, several or unclear lane markings
for a lane, e.g. in areas with road construction
work R
the lane markings are worn away, dark or cov-
e red up, e.g. by dirt or snow R
the distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted R
the lane markings change quickly, e.g. lanes
branch off, cross one another or merge R
the road is narrow and winding R
there are highly variable shade conditions on
the roadway

If you select the reverse gear, Active Blind Spot
Assist is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
When Active Blind Spot Assist is activated, gray
radar waves propagating backward appear next
to the vehicle in the assistance display in the
multifunction display. Above a speed of 20 mph
(30 km/h), the color of the radar waves in the
assistance display changes to green D . Active
Blind Spot Assist is then ready for use.
Visual and acoustic collision warning If you switch on the turn signals to change lanes
and a vehicle is detected in the side monitoring
range, you receive a visual and acoustic collision
warning. You will then hear a double warning
tone and red warning lamp C flashes. If the turn
signal remains on, detected vehicles are indica-
ted by the flashing of red warning lamp C .
There are no further warning tones.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of a lat-
eral collision in the monitoring range, a course-
correcting brake application is carried out. This
is meant to assist you in avoiding a collision.
G WARNING
A course-correcting brake application cannot
always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the
sides. If a course-correcting brake application occurs,
red warning lamp C flashes in the exterior mir-
ror and a double warning tone sounds. In addi-
tion, a display underlining the danger of a side
collision appears in the multifunction display.
In very rare cases, the system may make an
inappropriate brake application. A course-cor-
recting brake application may be interrupted at
any time by countersteering slightly or acceler-
ating.
The course-correcting brake application is avail-
able in the speed range between 20 mph
(30 km/h) and 120 mph (200 km/h).
Either no braking application, or a course-cor-
recting brake application adapted to the driving
situation occurs if: R
there are vehicles or obstacles, e.g. crash
barriers, located on both sides of your vehicle. R
a vehicle approaches you too closely at the
side. R
you have adopted a sporty driving style with
high cornering speeds. R
you clearly brake or accelerate. R
a driving safety system intervenes, e.g. ESP ®
or PRE-SAFE ®
Brake. R
ESP ®
is switched off. R
a loss of tire pressure or a defective tire is
detected.
Switching on Active Blind Spot Assist X
Make sure that Active Blind Spot Assist is
activated in the on-board computer
( Y
page 232). X
Switch on the ignition.
Warning lamps C in the exterior mirrors light
up red for approximately 1.5 seconds.
Gray radar waves propagating backwards
appear next to the vehicle in the assistance
graphic in the multifunction display D .
Above a speed of 20 mph (30 km/h), the color
of the radar waves in the assistance display
changes to green D . Active Blind Spot Assist
is then ready for use.Driving systems 211

able cargo and luggage load capacity is
650 lbs (1400 - 750 (5 x 150) = 650 lbs). X
Step 5: Determine the combined weight of
luggage and cargo being loaded on the vehi- cle. That weight may not safely exceed the
available cargo and luggage load capacity cal-
culated in step 4.
Example: steps 1 to 3 The following table shows examples on how to calculate total and cargo load capacities with varying
seating configurations and number and size of occupants. The following examples use a load limit of
1500 lbs (680 kg). This is for illustration purposes only. Make sure you are using the actual load
limit for your vehicle stated on your vehicle's Tire and Loading Information placard ( Y
page 359).
The greater the combined weight of the occupants, the lower the maximum luggage load.
