display. The set distance to a slower-moving
vehicle in front will then not be maintained.
You will be driving at the speed you deter-
mine by the position of the accelerator pedal.
You can also activate ICC when stationary.
The lowest speed that can be set is 20 MPH
(30 km/h).
Stopping
WARNING
•To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not leave
children, people who require the assis-
tance of others, or pets unattended in
your vehicle.
•The ICC system should only be used to
keep the vehicle stationary when the
driver is actively using the system.
When parking the vehicle, make sure to
turn OFF the ICC system, use the brake,
press the PARK (P) button, and place
the ignition switch in the LOCK position
prior to exiting the vehicle. Failure to do
so could lead to serious injury or death.
The ICC system will not hold the vehiclein place after coming to a stop when any
of the following conditions occur:
–There is a malfunction in the system
or in the voltage supply.
–The ICC system has been deactivated
with the cruise control lever, e. g. by a
vehicle occupant.
–The accelerator pedal has been de-
pressed, e.g. by a vehicle occupant.
For further information on deactivating the
ICC system, see "ICC switch (cruise control
lever)" earlier in this section
If the ICC system detects that the vehicle in
front is stopping, it brakes your vehicle until it
is stationary (within the braking limitations of
the system).
Once your vehicle is stationary, it remains
stationary and you do not need to depress
the brake.
NOTE
Depending on the specified minimum dis-
tance, your vehicle will come to a standstill
at a sufficient distance behind the vehicle in
front. The specified minimum distance is set
using the control on the cruise control lever.
How to change the set distance to
the vehicle ahead
The distance to the vehicle ahead can be
selected at any time depending on the traffic
conditions.
To increase the distance to the vehicle ahead,
turn the knob
3toward the rear2.To
decrease the distance to the vehicle ahead,
turn the knob
3toward the front1.
You can see this distance in the vehicle infor-
mation display.
The distance to the vehicle ahead will change
according to the vehicle speed. The higher the
vehicle speed, the longer the distance.

•As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive or
absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed
by depressing the brake pedal, depend-
ing on the distance to the vehicle ahead
and the surrounding circumstances in
order to maintain a safe distance be-
tween vehicles.
•If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system. Once the
vehicle is stationary, it remains station-
ary and you do not need to depress the
brake pedal.
•Always pay attention to the operation of
the vehicle and be ready to manually con-
trol the proper following distance. The
ICC system may not be able to maintain
the selected distance between vehicles
(following distance) or selected vehicle
speed under some circumstances.
•Normally when controlling the distance
to a vehicle ahead, this system auto-
matically accelerates or deceleratesyour vehicle according to the speed of
the vehicle ahead. If required, depress
the accelerator to properly accelerate
your vehicle when acceleration is re-
quired for a lane change. Depress the
brake pedal when deceleration is re-
quired to maintain a safe distance to the
vehicle ahead due to its sudden braking
or if a vehicle cuts in. Always stay alert
when using the ICC system.
•The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never
use the ICC system under the following
conditions:
–On roads where the traffic is heavy or
there are sharp curves.
–On slippery road surfaces such as on
ice or snow, etc.
–During bad weather (rain, fog, snow,
etc.).
–When rain, snow or dirt adhere to the
system sensor.
–On steep downhill roads (the vehicle
may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes).
–On repeated uphill and downhill
roads.–When traffic conditions make it diffi-
cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration.
–If there is interference by other radar
sources.
•Do not use the ICC system if you are
towing a trailer. The system may not de-
tect a vehicle ahead.
•In some road or traffic conditions, a ve-
hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. You may need to
control the distance from other vehicles
using the accelerator pedal. Always stay
alert and avoid using the ICC system
when it is not recommended in this sec-
tion.
•The distance sensor will not detect the
following objects:
–Stationary and slow moving vehicles.
–Pedestrians or objects in the road-
way.
–Oncoming vehicles in the same lane.
–Motorcycles traveling offset in the
travel lane.

FEB SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the FEB system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death.
•The FEB system cannot detect all ve-
hicles under all conditions.
•The radar sensor does not detect the
following objects:
–Pedestrians or animals
–Oncoming vehicles
–Crossing vehicles
•The radar sensor has some performance
limitations. For stationary vehicles, the
FEB system will not function when the
vehicle is driven at speeds over:
–
Approximately 31 MPH (50 km/h) for
the Autonomous braking function.
•The radar sensor may not detect a ve-
hicle ahead in the following conditions:
–Dirt, ice, snow or other material cov-
ering the radar sensor.
–Interference by other radar sources.
–Snow or heavy rain.
–If the vehicle ahead is narrow (e.g.
motorcycle).–If the vehicle ahead is in a different
lane.
–Under strong radar reflections, for
example, in a multi-level parking ga-
rage.
–New vehicle or after a maintenance
of the FEB system. For additional in-
formation, see "Break-in schedule"
later in this section
–When driving on a steep downhill
slope or roads with sharp curves.
–When towing a trailer.
•In some road or traffic conditions, the
FEB system may intervene unnecessar-
ily or give an unnecessary warning. Al-
ways pay careful attention to the traffic
situation. Do not rely solely on the dis-
tance warning function and terminate
the intervention if necessary.
•Braking distances increase on slippery
surfaces.
•The system is designed to automatically
check the sensor’s functionality, within
certain limitations. The system may not
detect some forms of obstruction of the
sensor area such as ice, snow, stickers,
for example. In these cases, the system
may not be able to warn the driver prop-
erly. Be sure that you check, clean and
clear the sensor area regularly.
•Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
SYSTEM TEMPORARILY
UNAVAILABLE
If the FEB stops working due to a malfunc-
tion or some other reason, one of the follow-
ing three messages will be displayed in the
vehicle information display.
•[Emergency Brake Currently Unavailable
See Operator's Manual]
•[Emergency Brake Inoperative]
•[Radar Sensors Dirty See Operator's
Manual]
For each of these messages, possible causes
and solutions are listed below.
[Emergency Brake Currently Unavailable
See Operator's Manual]:The FEB system is
temporarily inoperative. Possible causes:
•The radar sensor system is temporarily in-
operative, for example, due to electro-
magnetic radiation emitted by nearby TV
or radio stations or other sources of elec-
tromagnetic radiation.
Starting and driving5-67
CAUTION
Do not drive over obstacles such as curbs,
as you may damage the wheels or tires.
IPA may also display spaces not suitable for
parking, for example:
•Parking or stopping prohibition.
•In front of driveways or entrances and
exits.
•Unsuitable surfaces.
Parking tips:
•On narrow roads, drive as closely as pos-
sible past the parking space.
•Parking spaces that are littered or over-
grown might be identified or measured
incorrectly.
•Parking spaces that are partly occupied by
trailer towing bars might not be identified
as such or be measured incorrectly.
•Snowfall or heavy rain may lead to a park-
ing space being measured inaccurately.
•Pay attention to the sonar function warn-
ing messages during the parking proce-
dure.
•You can intervene in the steering proce-
dure to correct it at any time. IPA will then
be canceled.
•When transporting a load which protrudes
from your vehicle, you should not use IPA.
•Never use IPA when snow chains are fit-
ted.
•Make sure that the tire pressures are al-
ways correct. This has a direct influence on
the parking characteristics of the vehicle.
Use IPA for parking spaces that are:
•Parallel or at right angles to the direction
of travel.
•On straight roads, not bends.
•On the same level as the road, e. g. not on
the sidewalk.
For vehicles with the towbar folded out, the
minimum length for parking spaces is slightly
longer.
If you have attached a trailer to your vehicle,
you may not use IPA. Once the electrical
connection is established between your ve-
hicle and the trailer, IPA is no longer available.
The sonar function is deactivated for the rear
area
DETECTING PARKING SPACES
The IPA system can only be used to park in
spaces that have vehicles directly on either
side of the parking space.
Objects located above the height range of
IPA will not be detected when the parking
space is measured. These are not taken into
account when the parking procedure is calcu-
lated, e. g. overhanging loads, tail sections or
loading ramps of goods vehicles.
WARNING
If there are objects above the detection
range, IPA may steer too early. This could
cause a collision. There is a risk of an acci-
dent.
If objects are located above the detection
range, stop and switch off the IPA.
For further information on the detection
range see "Range of the sensors" later in this
section.
Starting and driving5-71
IPA does not assist you parking in spaces at
right angles to the direction of travel if:
•Two parking spaces are located directly
next to one another.
•The parking space is directly next to a low
obstacle such as a low curb.
•You forward park.
IPA does not assist you parking in spaces that
are parallel or at right angles to the direction
of travel if:
•The parking space is on a curb.
•The system reads the parking space as
being blocked, for example, by foliage or
grass paving blocks.
•The area is too small for the vehicle to
maneuver into.
•The parking space is bordered by an ob-
stacle, e.g. a tree, a post or a trailer.
1Detected parking space on the left.
2Parking symbol.
3Detected parking space on the right.
IPA is activated automatically when driving
forwards. The system is operational at speeds
of up to approximately 19 MPH (30 km/h).
While in operation, the system independently
locates and measures parking spaces on both
sides of the vehicle
IPA will only detect parking spaces:
•Adjacent to the vehicle.
•Parallel or at right angles to the direction
of travel.
•That are parallel to the direction of travel
and are at least 5 ft (1.5 m) wide.
•That are parallel to the direction of travel
and at least 3.3 ft (1.0 m) longer than your
vehicle.
•That are at right angles to the direction of
travel and at least 3.3 ft (1.0 m) wider than
your vehicle.
NOTE
IPA cannot measure the length of a parking
space if it is at right angles to the direction of
travel. You will need to judge whether your
vehicle will fit in the parking space
When driving at speeds below 19 MPH
(30 km/h) you will see parking symbol
2as a
status indicator in the vehicle information
display. When a parking space has been de-
tected, an arrow towards the right
3or the
left
1also appears. IPA only displays park-
ing spaces on the front-passenger side as
standard. Parking spaces on the driver's side
are displayed as soon as the turn signal on the
driver's side is activated. When parking on the
driver's side, this must remain activated until
you confirm the use of IPA by pressing the
tem automatically determines whether the
parking space is parallel or at right angles to
the direction of travel.
A parking space is displayed while you are
driving past it, and until you are approxi-
mately 50 ft (15 m) away from it.

SYSTEM MAINTENANCE
CAUTION
Keep the surface of the sonar sensors (if
equipped) (located on the front and rear
bumper fascia) free from accumulations of
snow, ice and dirt. Do not scratch the sur-
face of the sonar sensors when cleaning. If
the sensors are covered, the accuracy of
the sonar function will be diminished.During the first 1,200 miles (2,000 km), fol-
low these recommendations to obtain maxi-
mum engine performance and ensure the fu-
ture reliability and economy of your new
vehicle. Failure to follow these recommenda-
tions may result in shortened engine life and
reduced engine performance.
•Avoid driving for long periods at constant
speed, either fast or slow, and do not run
the engine over 4,000 RPM.
•Do not accelerate at full throttle in any
gear.
•Avoid quick starts.
•Avoid hard braking as much as possible.
•Do not tow a trailer for the first 500 mi
(805 km). Your engine, axle or other parts
could be damaged.
You should also observe these notes on
break-in if the engine or parts of the drive
train on your vehicle have been replaced.
CAUTION
In certain driving and driving safety sys-
tems, the sensors adjust automatically
while a certain distance is being driven af-
ter the vehicle has been delivered or after
repairs. Full system effectiveness is not
reached until the end of this teach-in pro-
cess.
Brake pads/linings and rotors that are ei-
ther new or have been replaced only
achieve optimum braking effect after sev-
eral hundred miles of driving. Compensate
for the reduced braking effect by applying
greater force to the brake pedal
BREAK-IN SCHEDULE
5-84Starting and driving
CAUTION
Never tow the vehicle with one axle raised.
This may damage the differential. Damage
of this sort is not covered by the warranty.
All wheels must be fully raised (see "Four-
Wheel Drive (4WD) models")
4WD, together with VDC, improves the trac-
tion of your vehicle whenever a drive wheel
spins due to insufficient grip.
If you fail to adapt your driving style, 4WD
can neither reduce the risk of an accident nor
override the laws of physics. 4WD cannot
take account of road, weather, and traffic
conditions. 4WD is only an aid. You are re-
sponsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time, and for staying in lane.
If a drive wheel spins due to insufficient grip
•When pulling away, only depress the ac-
celerator pedal as far as is necessary.
•Accelerate less when driving.
NOTE
In wintry driving conditions, the maximum
effectiveness of 4WD can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
WARNING
•Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
•Safe parking procedures require that
both the parking brake be applied and
the P (Park) position engaged. Failure to
do so could cause the vehicle to move
unexpectedly or roll away and result in
an accident.
•When parking the vehicle, make sure the
P (Park) position is engaged. The shift
lever cannot be moved out of the P
(Park) position without depressing the
brake pedal.
•Never leave the engine running while the
vehicle is unattended.
•Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls or move the
vehicle. Unattended children could be-
come involved in serious accidents.
•To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not leave
children, people who require the assis-
tance of others, or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm
day can quickly become high enough to
cause a significant risk of injury or death
to people and pets.
CAUTION
Always secure the vehicle correctly against
rolling away. Otherwise, the vehicle or its
drive train could be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally:
•The electric parking brake must be applied.
•The transmission must be in position P
(Park) and the transmission position dis-
play must show P in the vehicle informa-
tion display.
•The key must be removed from the ignition
switch.
•On uphill or downhill gradients, the front
wheels must be turned towards the curb.
