2016 MERCEDES-BENZ G-Class warning

Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate if the
system is not operating properly. The TPMS
malfunction indicator is combined with the
low tire pressure telltale. When the system
detects a malfunction, the warning lamp will
flash for approximately a minute and then
remain continuously illuminated. This
sequence will be repeated every time the vehi-
cle is started as long as the malfunction
exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons,
including the mounting of incompatible
replacement or alternate tires or wheels on
the vehicle that prevent the TPMS from func-
tioning properly. Always check the TPMS mal-
function telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels
allow the TPMS to continue to function prop-
erly.
It is the driver's responsibility to set the tire
pressure to the recommended cold tire pressure
suitable for the operating situation
(
Ypage 265). Note that the correct tire pressure
for the current operating situation must first be
taught-in to the tire pressure monitor. If there is
a substantial loss of pressure, the warning
threshold for the warning message is aligned to
the reference values taught-in. Restart the tire
pressure monitor after adjusting to the cold tire
pressure (
Ypage 270). The current pressures
are saved as new reference values. As a result, a
warning message will appear if the tire pressure
drops sign ificant
ly.
The tire pressure monitor does not warn you of
an incorrectly set tire pressure. Observe the
notes on the recommended tire pressure
(
Ypage 265).
The tire pressure monitor is not able to warn you
of a sudden loss of pressure, e.g. if the tire is
penetrated by a foreign object. In the event of a
sudden loss of pressure, bring the vehicle to a
halt by braking carefully. Avoid sudden steering
movements.
In order to check the tire pressure, the vehicle's
wheels are installed with sensors that monitor the tire pressure in all four tires. The tire pres-
sure monitor warns you if the pressure drops in
one or more of the tires. The tire pressure mon-
itor only functions if the correct sensors are
installed on all wheels.
The tire pressure monitor has a yellow warning
lamp in the instrument cluster for indicating
pressure loss/malfunctions (USA) or pressure
loss (Canada). Whether the warning lamp
flashes or lights up indicates whether a tire
pressure is too low or the tire pressure monitor is malfunctioning:
Rif the warning lamp is lit continuously, the tire
pressure on one or more tires is significantly
too low. The tire pressure monitor is not mal-
functioning.
RUSA only: if the warning lamp flashes for
around a minute and then remains lit con-
stantly, the tire pressure monitor is malfunc-
tioning.
Information on tire pressures is displayed in the
multifunction display. After a few minutes of
driving, the current tire pressure of each tire is
shown in the multifunction display.
USA only: the tire pressure warning lamp will
inform you of a malfunc
tion in the tire pressure
monitor by flashing for approximately one
minute and then remaining lit. It may take more
than ten minutes before the data menu is dis-
played. When the malfunction has been recti-
fied, the tire pressure warning lamp goes out
after a few minutes of driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at a gas station with a pressure gauge. The
tire pressures shown by the on-board computer
refer to those measured at sea level. At high
altitudes, the tire pressure values indicated by a
pressure gauge are higher than those shown by the on-board computer. In this case, do not
reduce the tire pressures.
The operation of the tire pressure monitor can
be affected by interference from radio transmit-
ting equipment (e.g. radio headphones, two-way
radios) that may be being operated in or near the
vehicle.

pressure display. The tire pressures are already
being monitored.
iIf a spare wheel is mounted, the system may
continue to show the tire pressure of the
wheel that has been removed for a few
minutes. Observe that the displayed value is
not the same as the current tire pressure of
the emergency spare wheel.
Tire pressure monitor warning mes-
sages
If the tire pressure monitor detects a significant
pressure loss on one or more tires, a warning
message is shown in the multifunction display. A
warning tone also sounds and the tire pressure
warning lamp lights up in the instrument cluster.
Each tire that is affected by a significant loss of
pressure is highlighted in the pressure display.
XIf the Correct Tire Pressuremessage
appears in the multifunction display, check
the tire pressure on all four wheels and cor-
rect it if necessary.
XIf the Check Tiresmessage appears in the
multifunction display, the tire pressure in one
or more tires has dropped significantly and
the tires must be checked.
XIf the Tire Press. Warning CautionTire Malfunctionmessage appears in the
multifunction display, the tire pressure in one

iIf the wheel positions on the vehicle are
rotated, the tire pressures may be displayed
for the wrong positions for a short time. This is
rectified after a few minutes of driving, and
the tire pressures are displayed for the cor-
rect positions.
Restarting the tire pressure monitor
When you restart the tire pressure monitor, all
existing warning messages are deleted and the
warning lamps go out. The monitor uses the cur-
rently set tire pressures as the reference values for monitoring. In most cases, the tire pressure
monitor will automatically detect the new refer-
ence values after you have changed the tire
pressure. However, you can also define refer-
ence values manually as described here.
XSet the tire pressure to the value recommen- ded for the corresponding driving situation on
the Tire and Loading Information placard on
the driver's side B-pillar (
Ypage 265).
Additional tire pressure values for different
loads can also be found on the tire pressure
table on the inside of the fuel filler flap
(
Ypage 265).

Loading the vehicle
Instruction labels for tires and loads
GWARNING
Overloaded tires can overheat, causing a
blowout. Overloaded tires can also impair the steering and driving characteristics and lead
to brake failure. There is a risk of accident.
Observe the load rating of the tires. The load
rating must be at least half of the GAWR of
your vehicle. Never overload the tires by
exceeding the maximum load.
:B-pillar, driver's side
Two instruction labels on your vehicle show the
maximum possible load.
(1) The Tire and Loading Information placard is on the B-pillar on the driver's side. The Tire
and Loading Information placard shows the
maximum permissible number of occu-
pants and the maximum permissible vehicle
load. It also contains details of the tire sizes
and corresponding pressures for tires
mounted at the factory.
(2) The vehicle identification plate is on the B- pillar on the driver's side. The vehicle iden-
tification plate informs you of the gross
vehicle weight rating. It is made up of the
vehicle weight, all vehicle occupants, the
fuel and the cargo. You can also find infor-
mation about the maximum gross axle
weight rating on the front and rear axle.
The maximum gross axle weight rating is
the maximum weight that can be carried by
one axle (front or rear axle). Do not exceedthe maximum gross vehicle weight or the
maximum gross axle weight rating for the
front or rear axle.

on the government test track as a tire graded
100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm, due to
variations in driving habits, service practices
and differences in road characteristics and cli-
mate conditions.
Traction
GWARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction char-
acteristics.
!Avoid wheelspin. This can lead to damage to
the drive train.
The traction grades, from highest to lowest, are
AA, A, B, and C. Those grades represent the
tire's ability to stop on a wet surface as meas-
ured under controlled conditions on specified
government test surfaces of asphalt and con-
crete. A tire marked C may have poor traction
performance.
The safe speed on a wet, snow covered or icy
road is always lower than on dry road surfaces.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Mercedes-Benz recommends a minimum tread
depth of ãin (4 mm) on all four winter tires.
Observe the legally required minimum tire tread
depth (
Ypage 263). Winter tires can reduce the
braking distance on snow-covered surfaces in
comparison with summer tires. The braking dis-
tance is still much further than on surfaces that
are not icy or covered with snow. Take appro-
priate care when driving.
Further information on winter tires (M+S tires)
(
Ypage 264).
Temperature
GWARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla-
tion, or excessive loading, either separately or
in combination, can cause excessive heat
build-up and possible tire failure.
The temperature grades are A (the highest), B,
and C. These represent the tire's resistance to
the generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel. Sus-
tained high temperature can cause the material
of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of
performance which all passenger car tires must meet under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A represent
higher levels of performance on the laboratory
test wheel than the minimum required by law.

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

that weigh more than the replaced standard
parts and more than 2.3 kg (5 lbs). These
optional extras, such as high-performance
brakes, level control, a roof rack or a high-per-
formance battery, are not included in the curb
weight and the weight of the accessories.
TIN (Tire Identification Number)
This is a unique identifier which can be used by
a tire manufacturer to identify tires, for example
for a product recall, and thus identify the pur-
chasers. The TIN is made up of the manufactur- er's identity code, tire size, tire type code and
the manufacturing date.
Load bearing index
The load bearing index (also load index) is a code
that contains the maximum load bearing capa-
city of a tire.
Traction
Traction is the result of friction between the tires
and the road surface.
TWR (Tongue Weight Rating)
The TWR specifies the maximum permissible
weight that the ball coupling of the trailer tow
hitch can support.

Changing a wheel
Flat tire
The "Breakdown assistance" section
(Ypage 250) contains information and notes on
how to deal with a flat tire.
Rotating the wheels
GWARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions. The wheel brakes or suspension components
may also be damaged. There is a risk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
!On vehicles equipped with a tire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at a qualified spe-
cialist workshop.
Rotating front and rear wheels of differing
dimensions can render the general operating
permit invalid.
Always pay attention to the instructions and
safety notices in the section on "Changing a
wheel and mounting a spare wheel"
(
Ypage 282).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires in
the center.
If your vehicle's tire configuration allows, you
can rotate the wheels according to the intervals
in the tire manufacturer's warranty book in your
vehicle documents. If no warranty book is avail-
able, the tires should be rotated every 3,000 to
6,000 miles (5,000 to 10,000 km), or earlier if
tire wear requires. Do not change the direction
of wheel rotation.
Clean the contact surfaces of the wheel and the brake disc thoroughly every time a wheel is rota-

ted. Check the tire pressure and reactivate the
tire pressure monitor (Ypage 268)if necessary.
Direction of rotation
Tires with a specified direction of rotation have
additional benefits, e.g. if there is a risk of hydro-
planing. You will only gain these benefits if the
correct direction of rotation is observed.
An arrow on the sidewall of the tire indicates its
correct direction of rotation.
You may mount the spare wheel against the
direction of rotation. Adhere to the time restric-
tion on use as well as the speed limitation speci-
fied on the spare wheel.
Storing wheels
Store tires that are not being used in a cool, dry
and preferably dark place. Protect the tires from
oil, grease, gasoline and diesel.
Mounting a wheel
Preparing the vehicle
GWARNING
When you remove the spare wheel from the
spare wheel bracket, the vehicle’s weight dis-
tribution changes. If the vehicle is already
raised, the jack could tip over. There is a risk
of injury.
Remove the spare wheel from the spare wheel
bracket before lifting the vehicle.
XPrepare the vehicle as described
(Ypage 250).
XRemove the vehicle tool kit and the jack
(Ypage 248).
XSecure the vehicle to prevent it from rolling
away.
XRemove the spare wheel from the spare wheel
bracket (Ypage 249).
iVehicles without a spare wheel or emer-
gency spare wheel are not equipped with a
tire-change tool kit at the factory. For more
information on which tools are required to
perform a wheel change on your vehicle e.g. lug wrench or jack, consult an authorized
Mercedes-Benz Center.
Securing the vehicle to prevent it from
rolling away
XOn level ground:
place chocks or other suit-
able items under the front and rear of the
wheel that is diagonally opposite the wheel
you wish to change.
XOn downhill gradients: place chocks or
other suitable items in front of the wheels of
the front and rear axle.
Raising the vehicle
GWARNING
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
!The jack is designed exclusively for jacking
up the vehicle at the jacking points. Other-
wise, your vehicle could be damaged.
Observe the following when raising the vehicle:
RTo raise the vehicle, only use the vehicle-spe-
cific jack that has been tested and approved
by Mercedes-Benz. If used incorrectly, the
jack could tip over with the vehicle raised.
RThe jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed. It is not suited for performing main-
tenance work under the vehicle.
RAvoid changing the wheel on uphill and down- hill slopes.
RBefore raising the vehicle, secure it from roll-
ing away by applying the parking brake and
inserting wheel chocks. Do not disengage the
parking brake while the vehicle is raised.
RThe jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a large,
load-bearing underlay must be used. On a
slippery surface, a non-slip underlay must be
used, e.g. rubber mats.
RDo not use wooden blocks or similar objects
as a jack underlay. Otherwise, the jack will not
