2013 MERCEDES-BENZ G-CLASS SUV air condition

road, weather and traffic conditions.
DISTRONIC PLUS is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in lane. Only engage
DISTRONIC PLUS when the current road,
weather and traffic
conditions
permit it to be
done safely, and adapt your driving style
accordingly. Drive carefully and maintain a
suitable distance to the vehicle in front.
If DISTRONIC PLUS detects a risk of collision
but cannot sufficiently decelerate the vehicle
in order to maintain the set distance, you will
be warned visually and acoustically.
DISTRONIC PLUS cannot prevent a collision
without your intervention. An intermittent
warning tone will then sound and the distance
warning lamp will light up in the instrument
cluster. Brake immediately in order to
increase the distance from the vehicle in
front, or take evasive action, provided it is
safe to do so.
DISTRONIC PLUS may not detect narrow
vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line. Therefore,
always pay attention to traffic conditions
even when DISTRONIC PLUS is activated.
Otherwise, you may fail to recognize dangers
in time, cause an accident and injure yourself
and others.
In particular, the detection of obstacles can
be impaired if there is:
R the sensor is dirty or covered
R snow or heavy rain
R interference by other radar sources
R there is the possibility of strong radar
reflections, for example, in parking
garages.
If DISTRONIC PLUS is activated, the vehicle
brakes automatically in certain situations.
This can happen unexpectedly, especially
when towing or in a car wash. There is a risk
of an accident. In these or similar situations,
deactivate DISTRONIC PLUS.
If you want DISTRONIC PLUS to assist you,
the following activation conditions must be fulfilled (
Y page 179) and the radar sensor
system must be operational.
General notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the
distance to the vehicle detected in front.
DISTRONIC PLUS brakes automatically so
that the set speed is not exceeded.
On long and steep downhill gradients,
especially if the vehicle is laden or towing a
trailer, you must select shift range
1, 2 or 3
in good time. By doing so, you will make use
of the braking effect of the engine, which
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly.
If DISTRONIC PLUS detects a slower-moving
vehicle in front, your

vehicle is braked in order
to maintain the preset distance to the vehicle
in front.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control in the speed range between 20 mph
(Canada: 30 km/h) and120 mph (Canada:
200 km/h). If a vehicle is driving in front of
you, it operates in the speed range between
0 mph (0 km/h) and 120 mph (Canada:
200 km/h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS transmits radar waves,
it can resemble the radar detectors of the
responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
questions are asked about this.

crossing traffic, for example, could cause
your vehicle to pull away unintentionally. Blind Spot Assist
Important safety notes G
WARNING
Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles approaching and driving by with a
speed difference of more than
approximately 11 km/h
As a result, Blind Spot Assist may not give
warnings in such

situations. There is a risk of
an accident.
Always observe the traffic conditions
carefully, and maintain a safe lateral distance. G
WARNING
Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles approaching and driving by with a
speed difference of more than 6.8 mph
(11 km/h)
As a result, Blind Spot Assist may not give
warnings in such

situations. There is a risk of
an accident. Always observe the traffic conditions
carefully, and maintain
a

safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or anything else
covering the sensors.
R visibility is poor, e.g. due to fog, heavy rain
or snow.
R there is a narrow vehicle traveling in front,
e.g. a motorcycle or bicycle.
R the road has very wide lanes.
R the road has narrow lanes.
R you are not driving in the middle of the lane.

General notes Active Blind Spot Assist uses a radar sensor
system to monitor the side areas of your
vehicle which are in back of the driver. A warning display in the exterior mirrors draws
your attention to vehicles detected in the
monitored area. If you then switch on the
corresponding turn signal to change lanes,
you will also receive an optical and audible
collision warning. If a risk of lateral collision
is detected, corrective braking may help you
avoid a collision. To support the course-
correcting brake application, Active Blind
Spot Assist also
uses
the forward-facing radar
sensor system.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph(30 km/h).
Monitoring area G
WARNING
Active Blind Spot Assist monitors certain
areas in the immediate

vicinity of your vehicle.
Vehicles that approach and drive past at high
speeds are not detected. No visual nor
audible warnings are emitted and the system
does not brake the vehicle to correct your
course.
If the lanes are very wide, it may not be
possible to monitor the complete width of the
neighboring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in a staggered formation.
This may be the case if vehicles are driving at
that edge of their lane which is furthest away
from your vehicle.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognize dangers in time, cause an accident
and injure yourself and others. Driving systems

Driving and parking Z

i
In wintry driving conditions,
the maximum
effect of 4MATIC can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
For information about driving off-road, see
(Y page 164). PARKTRONIC
Important safety notes !
When parking, pay particular

attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or a pneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a
replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting a parking space. Check in front,
behind and to the sides of the vehicle before
maneuvering, parking or exiting a parking
space. There must not be any persons,
animals or objects in the area in which you
are maneuvering.
PARKTRONIC cannot identify any persons or
objects outside of the detection range. As a
result, PARKTRONIC cannot warn you about
objects in this area. PARKTRONIC is activated automatically when
you:
R
switch on the ignition
R shift the transmission
to

position D, R or N
R release the parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.

display. If you then release the parking
brake, a warning tone will sound.
Differential locks
General notes G
WARNING
When differential locks are engaged on a firm,
high-grip surface, the vehicle's steerability is
greatly impaired. In particular, engaging the
differential locks when cornering could lead
to you losing control
of the vehicle. There is a
risk of an accident.
Disengage the differential locks immediately
on firm, high-grip surfaces. G
WARNING
ABS, 4ETS, ESP ®
and BAS are deactivated
while the differential locks are engaged. As a
result, the wheels could lock when braking
and the braking distance is increased. There
is a risk of an accident.
Disengage the differential locks immediately
on firm, high-grip surfaces.
! In order to avoid damage to the transfer
case, you must operate the vehicle on a
dynamometer (1-axle dynamometer) only
if:
R the axle not driven on is jacked up
or
R the corresponding propeller shaft is
disconnected and the transfer case
differential lock is activated.
Otherwise, the transfer case can be
damaged.
Differential locks improve the traction of the
vehicle. Your vehicle is equipped with a differential
lock for:
R
the transfer case: this

controls the balance
between the front and rear axles.
R the rear axle: this controls the balance
between the wheels on the rear axle.
R the front axle: this controls the balance
between the wheels on the front axle.
Information on differential and
differential locks When the vehicle drives around a curve, the
wheels on the
outside

of the curve must cover
a greater distance. Therefore, the wheels turn
more rapidly than on the inside. The
differential, a transmission in the drive train,
compensates for these different rotational
speeds, making cornering possible.
The disadvantage of a differential is that more
power is transferred to the wheels that have
the least grip. An example: a wheel of a driven
axle is on a snow-covered surface and
therefore does not have any traction. The
differential causes this wheel to be subjected
to the strongest driving force, as the flow of
force takes the path of least resistance. The
opposite wheel on this axle, however, which
stands on firm ground and could therefore
allow propulsion, receives no driving power.
4ETS compensates for this disadvantage.
4ETS provides good steerability by
automatically braking the spinning wheel.
4ETS provides the wheel on the firm surface
with more drive force, which in turn provides
propulsion.
ESP® and 4ETS are traction systems that are
ideal for road driving and suitable for light off-
road driving. The LOW RANGE off-road gear
also improves off-road capability.
Moreover, the more difficult conditions in off-
road driving require further measures such as
locking one or several differentials. Your
vehicle is equipped with three differential
locks: Off-road driving systems

WARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The
vehicle/trailer combination could even
rollover. There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer
combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary. G
WARNING
If you install a ball coupling other than the one
delivered with the vehicle,

the trailer tow hitch
and the rear axle may be overloaded. This
applies especially if the ball coupling in
question is longer or angled differently. This
could seriously impair the driving
characteristics and the trailer can come
loose. There is a risk of an accident.
Only install the ball coupling delivered with
the vehicle or a ball coupling that is designed
to meet your trailer towing requirements. Do
not modify the ball coupling or the trailer tow
hitch. G
WARNING
If the ball coupling is not installed correctly or
not secured with the bolt provided and the
corresponding spring cotter, the trailer may
come loose. There is a risk of an accident.
Always install and secure

the ball coupling as
described. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter.
Please observe the manufacturer's operating
instructions for the trailer coupling if a
detachable trailer coupling is used.
You will find the applicable permissible
values, which must not be exceeded, in the
vehicle documents. You will find the values
approved by the manufacturer on the vehicle
identification plates and those for the towing
vehicle in the "Technical data" section
(Y page 349). Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
Make sure that the following values are not
exceeded:
R
the permissible trailer drawbar

noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
with when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and
gradient-climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R has a larger turning circle
This could impair the handling
characteristics.
When towing a trailer, always adjust your
speed to the current road and weather
conditions. Do not exceed the maximum
permissible speed for your vehicle/trailer
combination.
General notes R
Do not exceed the legally prescribed
maximum speed for vehicle/trailer
combinations in the relevant country.
This lowers the risk of an accident.
R Only install an approved

trailer coupling on
your vehicle.
