Reactivating Advanced TPMS
The TPMS must be reactivated when you
have adjusted the tire inflation pressure to
a new level (e.g. because of different load
or driving conditions). The TPMS is then
recalibrated to the current tire inflation
pressures.\1Using the tire and loading information
placard on the driver’s door B-pillar
(\2page 206), make sure the tire infla-
tion pressure of all four tires is correct.
\1Press buttonè orÿ on the mul-
tifunction steering wheel repeatedly
until the standard display menu ap-
pears in the multifunction display
(\2page 93).
TPMS malfunctions may occur for a variety
of reasons, including the installation of in-
compatible replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction 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 properly.iIf a condition causing the TPMS to mal-
function develops, it may take up to 10
minutes for the system to signal a mal-
function using the TPMS telltale flash-
ing and illumination sequence.
The telltale extinguishes after driving a
few minutes if the malfunction has
been corrected.
iOperating radio transmission equip-
ment (e.g. wireless headsets, two-way
radios) in or near the vehicle could
cause the TPMS to malfunctionWarning!
G
It is the driver’s responsibility to calibrate
the TPMS on the recommended cold infla-
tion pressure. Underinflated tires affect the
ability to steer or brake the vehicle. You
might lose control over the vehicle.
iReactivate the TPMS after adjusting
the tire inflation pressure to the infla-
tion pressure recommended for the ve-
hicle operating condition. Tire pressure
should only be adjusted on cold tires.
Observe the recommended tire infla-
tion pressure on the tire and loading in-
formation placard on the driver’s door
B-pillar (\2page 206).

Potential problems associated with un-
derinflated and overinflated tires
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Three primary areas are affected
by improper tire inflation pressure:
1. Safety
2. Economy
Improper inflation pressures can cause un-
even wear patterns to develop across the
tire tread. These abnormal wear patterns
will reduce tread life resulting in a need for
earlier tire replacement. Underinflation
also increases tire rolling resistance and
results in higher fuel consumption.
Warning
G
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adverse-
ly affect handling and fuel economy, and are
more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride com-
fort, wear unevenly, increase stopping dis-
tance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road de-
bris, potholes etc.Warning
G
Improperly inflated tires are dangerous and
can cause accidents.
Unequal tire inflation pressures can cause
steering problems. You could lose control of
your vehicle.
Unequal tire inflation pressures from one
side of the vehicle to the other can cause
the vehicle to drift to the right or left. Always
drive with each tire inflated to the recom-
mended cold tire inflation pressure.

3. Ride comfort and vehicle stability
Proper tire inflation contributes to a com-
fortable ride. Overinflation produces a jar-
ring and uncomfortable ride.
Besides the tire name (sales designation)
and manufacturer's name, a number of
markings can be found on a tire.
Below are some explanations regarding
the markings on your vehicle’s tires:

Tire sizes for Sprinter vehicles
Design standard
Depending on the design standards used,
the tire size molded into the side wall may
have no letter or a letter1 preceding the
tire width or the tire load rating designa-
tion.
Letter “LT” preceding the size designation:
Light Truck tire based on U.S. design stan-
dards.
Letter “C” preceding the tire load designa-
tion:
Commercial vehicle tire based on Europe-
an design standards.
Tire width
The tire width2 indicates the nominal tire
width in mm.Aspect ratio
The aspect ratio3 is the dimensional re-
lationship between tire section height and
section width and is expressed in percent-
age. The aspect ratio is arrived at by divid-
ing section height by section width.
Tire code
The tire code4 indicates the tire con-
struction type. The “R” stands for radial
tire type. Letter “D” means diagonal or bias
ply construction; letter “B” means belted-
bias ply construction.
Rim diameter
The rim diameter5 is the diameter of the
bead seat, not the diameter of the rim
edge. Rim diameter is indicated in
inches (in).
Tire load rating
The tire load rating6 is a numerical code
associated with the maximum load a tire
can support.For example, a load rating of 120 corre-
sponds to a maximum load of 3042 lbs
(1380 kg) the tire is designed to support.
If two values are given (as illustrated), the
first value, preceding the slash "/", applies
to single tires (rear axle). The second val-
ue, succeeding the slash "/", applies to
twin tires (dual wheel rear axle).
The commercial vehicle tires based on Eu-
ropean standards may have an additional
value in the parentheses (as illustrated). In
such cases, the value preceding the paren-
theses is valid for European countries and
the parenthesized for the USA and Canada.
Refer also to "Maximum tire load"
(\2page 226) where the maximum load as-
sociated with the load index is indicated in
kilograms and lbs.

Tire speed rating
The tire speed rating6 indicates the ap-
proved maximum speed for the tire.
The commercial vehicle tires based on Eu-
ropean standards may have an additional
index in the parentheses. In such cases,
the index preceding the parentheses is val-
id for European countries and the paren-
thesized for the USA and Canada.
Warning
G
The tire load rating must always be at least
h a l f o f t h e G A W R o f y o u r v e h i c l e . O t h e r w i s e ,
tire failure may be the result which may
cause an accident and/or serious personal
injury to you or others.
Always replace rims and tires with the same
designation, manufacturer and type as
shown on the original part.Warning
G
Do not overload the tires by exceeding the
specified load limit as indicated on the plac-
ard located on the driver’s door B-pillar.
Overloading the tires can overheat them,
possibly causing a blowout. Overloading the
tires can also result in handling or steering
problems, or brake failure.
iTire load rating6 and tire speed
rating7 are also referred to as “ser-
vice description”.
Warning
G
Even when permitted by law, never operate
a vehicle at speeds greater than the maxi-
mum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire fail-
ure, causing loss of vehicle control and pos-
sibly resulting in an accident and/or
personal injury and possible death, for you
and for others.iAlways observe the speed rating of the
winter tires installed on your Sprinter
vehicle. If the maximum speed for
which your tires are rated is below the
speed rating of your Sprinter vehicle,
you must place a notice to this effect
where it will be seen by the driver.
Such notices are available at your tire
dealer or any authorized Sprinter Deal-
er.

U.S. tire regulations require each new tire
manufacturer or tire retreader to mold a
TIN into or onto a side wall of each tire pro-
duced.The TIN is a unique identifier which facili-
tates efforts by tire manufactures to notify
purchasers in recall situations or other
safety matters concerning tires and gives
purchasers the means to easily identify
such tires.
The TIN is comprised of the “manufactur-
er’s identification mark”, “tire size”, “tire
type code” and “date of manufacture”.
1DOT
2Manufacturer’s identification mark
3Tire size
4Tire type code (tire manufacturer's op-
tion)
5Date of manufactureThe TIN may be found on one or both sides
of the tire; however, the date code may
only be on one side. Tires with white side
walls will have the full TIN including date
code located on the white side wall side of
the tire. Look for the TIN on the outboard
side of black side wall tires as mounted on
the vehicle.
If the TIN is not found on the outboard side
then you will find it on the inboard side of
the tire. In this case, the tire must be re-
mounted. Make sure the TIN is visible on
the outboard side of the tire and if applica-
ble that the direction of rotation is correct
when remounting the tire.
