2016 MERCEDES-BENZ G-Class width

Vehicles traveling on a different line
DISTRONIC PLUS may not detect vehicles trav-
eling on a different line. The distance to the
vehicle in front will be too short.
Other vehicles changing lanes
DISTRONIC PLUS has not detected the vehicle
cutting in yet. The distance to this vehicle will be
too short.
Narrow vehicles
DISTRONIC PLUS has not yet detected the vehi-
cle in front on the edge of the road, because of
its narrow width. The distance to the vehicle in
front will be too short.
Obstructions and stationary vehicles
DISTRONIC PLUS does not brake for obstacles
or stationary vehicles. If, for example, the detec-
ted vehicle turns a corner and reveals an obsta-cle or stationary vehicle, DISTRONIC PLUS will
not brake for these.
Crossing vehicles
DISTRONIC PLUS may detect vehicles that are
crossing your lane by mistake. Activating
DISTRONIC PLUS at traffic lights with crossing
traffic, for example, could cause your vehicle to
pull away unintentionally.

severe corrosion on wheels, for example.
Damaged wheels can cause a loss of tire pres-
sure.
RRegularly check the tire tread depth and the
condition of the tread across the whole width
of the tire (
Ypage 263). In order to inspect
the inner side of the tire surface, turn the
steering wheel to full lock.
RAll wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
install anything onto the valve other than the
standard valve cap or a valve cap approved by Mercedes-Benz for your vehicle.
Do not install anything onto the valve, such as
tire pressure monitoring systems.
RYou should regularly check the pressure of all
your tires including the spare wheel, particu-
larly prior to long trips. Adjust the tire pres-
sure as necessary (
Ypage 270).
The service life of tires depends, among other
things, on the following factors:
RDriving style
RTire pressure
RDistance covered
Tire tread
GWARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where speed is not adapted to suit the driving con-
ditions. There is a risk of accident.
If the tire pressure is too high or too low, tires
may exhibit different levels of wear at differ-
ent locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
RSummer tires: âin (3 mm)
RM+S tires: ãin (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached.
Marking :shows the tread wear indicator
(TWI). The arrow indicates the placement of the
tire tread.
Do not drive with tires which have too little tread
depth. tire traction on wet road surfaces decrea-
ses significantly when the tread depth is less
than
1/8in (3 mm).
Treadwear indicators (TWI) are required by law.
Six indicators are positioned over the tire tread.
They are visible once the tread depth is approx-
imately
1/16in (1.6 mm). If this is the case, the
tire is so worn that it must be replaced.
The recommended tread depth for summer tires
is at least
1/8in (3 mm). The recommended
tread depth for winter tires is at least1/6in
(4 mm).
Selecting, mounting and replacing
tires
ROnly mount tires and wheels of the same type
and make.
ROnly mount approved tires of the correct size
onto the wheels.
RTires are supplied with a protective layer from
the factory. Break in new tires at moderate
speeds for the first 60 miles (100 km). They
only reach their full performance after this
distance.
RDo not drive with tires which have too little
tread depth, as this significantly reduces the
traction on wet roads (hydroplaning).
RReplace the tires after six years at the latest,
regardless of wear. This also applies to the
spare wheel.

Vehicle identification plate
Even if you have calculated the total load care-
fully, you should still make sure that the gross
vehicle weight rating and the gross axle weight
rating are not exceeded. Details can be found on
the vehicle identification plate on the B-pillar on
the driver's side of the vehicle (
Ypage 271).
Gross vehicle weight rating: the gross weight
of the vehicle, all passengers, load and trailer
load/noseweight (if applicable) must not
exceed the gross vehicle weight rating.
Gross Axle Weight Rating (GAWR): the maxi-
mum permissible weight that can be carried by
one axle (front or rear axle).
To ensure that your vehicle does not exceed the
maximum permissible values (gross vehicle
weight and maximum gross axle weight rating),
have your loaded vehicle (including driver, occu-
pants, load and full trailer load if applicable)
weighed on a suitable vehicle weighbridge.
Trailer load/noseweight
The trailer load/noseweight affects the gross
weight of the vehicle. If a trailer is attached, the trailer load/noseweight is included in the load
along with occupants and luggage. The trailer
load/noseweight is usually approximately 10 %
of the gross weight of the trailer and its load.
Only use a trailer tow hitch that has been
approved for your vehicle by Mercedes-Benz.
Comply with the manufacturer's operating
instructions for operation, care and mainte-
nance.
Uniform Tire Quality Grading Stand-
ards
Overview of Tire Quality Grading
Standards
Uniform Tire Quality Grading Standards are U.S.
government specifications. Their purpose is to
provide drivers with uniform reliable informationon tire performance data. Tire manufacturers
have to grade tires using three performance fac-
tors: :tread wear grade, ;traction grade and
= temperature grade. These regulations do not
apply to Canada. Nevertheless, all tires sold in
North America are provided with the corre-
sponding quality grading markings on the side-
wall of the tire.
Where applicable, the tire grading information
can be found on the tire sidewall between the
tread shoulder and maximum tire width.
Example:
RTreadwear grade: 200
RTraction grade:AA
RTemperature grade: A
All passenger car tires must conform to the stat-
utory safety requirements in addition to these
grades.
iThe actual values for tires are vehicle-spe-
cific and may deviate from the values in the
illustration.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified U.S.
government course. For example, a tire graded
150 would wear one and one-half times as well

Tire size designation, load-bearing
capacity and speed rating
GWARNING
Exceeding the stated tire load-bearing capa-
city and the approved maximum speed could
lead to tire damage or the tire bursting. There is a risk of accident.
Therefore, only use tire types and sizes
approved for your vehicle model. Observe the
tire load rating and speed rating required for
your vehicle.

General: depending on the manufacturer's
standards, a letter is imprinted into the tire wall before the size description.
If there is no letter preceding the size descrip-
tion (as shown above): these are passenger
vehicle tires according to European manufac-
turing standards.
If "P" precedes the size description: passenger
vehicle tires according to U.S. manufacturing
standards. If "P" precedes the size description: light truck
tires according to U.S. manufacturing stand-
ards.
If "T" precedes the size description: these are
compact emergency spare wheels at high tire
pressure, to be used only temporarily in an
emergency.
Tire width:
tire width:shows the nominal tire
width in millimeters.
Height-width ratio: height-width ratio;is the
ratio between tire height and tire width. The
aspect ratio is calculated by dividing the tire
width by the tire height. The resulting quotient is
given as a percentage.
Tire code: tire code=shows the tire type. "R"
represents radial tires; "D" represents diagonal
tires; "B" represents diagonal radial tires.
Optionally, tires with a maximum speed of over
149 mph (240 km/h) may have "ZR" in the size
description, depending on the manufacturer
(e.g. 245/40 ZR 18).
Rim diameter: rim diameter?is the diameter
of the bead seat, not the diameter of the rim
flange. The rim diameter is specified in
inches (in).
The load-bearing index: load-bearing indexA
(also load index), is a code that contains the
maximum load-bearing capacity of a tire.
Do not overload the tires by exceeding the
specified load limit. The maximum permissible
load can be found on the vehicle's Tire and
Loading Information placard on the B-pillar on
the driver's side (
Ypage 271).
Example:
Load-bearing index 91 indicates a maximum
load of 1,356 lb (615 kg) that the tires can bear.
For further information on the maximum tire
load in kilograms and pounds, see
(
Ypage 278).
For further information on the load bearing
index, see "Load index" (
Ypage 277).
Speed rating: speed ratingBspecifies the
approved maximum speed of the tire.
iTire data is vehicle-specific and may deviate
from the data in the example.
Regardless of the speed rating, always observe
the speed limits. Drive carefully and adapt your
driving style to the traffic conditions.
iSince 2009, tires in Europe which corre-
spond to the noise limitations of Directive
ECE-R 117 show an >>S<< (Sound) mark. This

the drawbar noseweight, if applicable. The gross
vehicle weight must not exceed the gross vehi-
cle weight rating GVWR as specified on the vehi-
cle identification plate on the B-pillar on the
driver's side.
GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permissible gross
weight of a fully loaded vehicle (the weight of thevehicle including all accessories, occupants,
fuel, luggage and the drawbar noseweight, if
applicable). The gross vehicle weight rating is
specified on the vehicle identification plate on
the B-pillar on the driver's side.
Maximum loaded vehicle weight
The maximum weight is the sum of:
Rthe curb weight of the vehicle
Rthe weight of the accessories
Rthe load limit
Rthe weight of the factory installed optional
equipment
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa corre-
sponds to 1 psi. Another unit for tire pressure is
bar. 100 kilopascal s(kPa) are the equivalent of
1 bar.
Load index
In addition to the load-bearing index, the load
index may also be imprinted on the sidewall of
the tire. This specifies the load-bearing capacity
more precisely.
Curb weight
The weight of a vehicle with standard equipment
including the maximum capacity of fuel, oil and
coolant. It also includes the air-conditioning sys-
tem and optional equipment if these are instal-
led in the vehicle, but does not include passen-
gers or luggage.
Maximum load rating
The maximum load rating is the maximum per-
missible weight in kilograms or lbs for which a
tire is approved.
Maximum permissible tire pressure
Maximum permissible tire pressure for one tire.
Maximum load on one tire
Maximum load on one tire. This is calculated by
dividing the maximum axle load of one axle by
two.
PSI (pounds per square inch)
A standard unit of measure for tire pressure.
Aspect ratio
Relationship between tire height and tire width
in percent.
Tire pressure
This is pressure inside the tire applying an out-
ward force to each square inch of the tire's sur-
face. The tire pressure is specified in pounds per
square inch (psi), in kilopascals (kPa) or in bar.
The tire pressure should only be corrected when
the tires are cold.
Cold tire pressure
The tires are cold:
Rif the vehicle has been parked without direct
sunlight on the tires for at least three hours
and
Rif the vehicle has not been driven further than
1 mile (1.6 km)
Tread
The part of the tire that comes into contact with
the road.
Bead
The tire bead ensures that the tire sits securely
on the wheel. There are several steel wires in the
bead to prevent the tire from coming loose from
the wheel rim.
Sidewall
The part of the tire between the tread and the
bead.
