Reactivating the Advanced TPMSThe 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 in-
flation pressures.
\1
Make sure the tire inflation pressure
of all four tires is correct, using the
tire and loading information placard
1
or the tire inflation pressure placard
located on the driver’s door B-pillar
(
\2
page 362).
Warning!
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.
1. For vehicles with a gross weight capacity less
than 10 000 lbs (4 536 kg) (USA only).
iReactivate the TPMS after adjusting
the tire inflation pressure to the infla-
tion pressure recommended for the
vehicle operating condition. Tire in-
flation pressure should only be adju-
sted on cold tires. Observe the
recommended tire inflation pressure
on the tire and loading information
placard
1 or on the tire inflation pres-
sure placard on the driver’s door B-
pillar (\2
page 362).

1. Safety 2. Economy
Improper inflation pressures can cause
uneven wear patterns to develop across
the tire tread. These abnormal wear pat-
terns will reduce tread life resulting in a
need for earlier tire replacement. Under-
inflation also increases tire rolling resis-
tance 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, ad-
versely affect handling and fuel economy,
and are more likely to fail from being over-
heated.
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. Al-
ways drive with each tire inflated to the
recommended cold tire inflation pres-
sure.

The commercial vehicle tires based on
European standards may have an addi-
tional value in the parentheses (as illus-
trated). In such cases, the value
preceding the parentheses is valid for
European countries and the parenthe-
sized for the USA and Canada.
Refer also to "Maximum tire load"
(\2
page 390) where the maximum load
associated with the load index is indicat-
ed in kg and lbs.
Warning
G
The tire load rating must always be at
least half of the GAWR of your vehicle.
Otherwise, tire failure may be the result
which may cause an accident and/or se-
rious 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
placard located on the driver’s door B-pil-
lar. Overloading the tires can overheat
them, possibly causing a blowout. Over-
loading the tires can also result in han-
dling or steering problems, or brake
failure.iTire load rating

Tire speed ratingThe tire speed rating

indicates the
approved maximum speed for the tire.
The commercial vehicle tires based on
European standards may have an addi-
tional index in the parentheses. In such
cases, the index preceding the paren-
theses is valid for European countries
and the parenthesized for the USA and
Canada.
Warning
G
Even when permitted by law, never oper-
ate a vehicle at speeds greater than the
maximum 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
possibly 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
Dealer.

consumers with ratings for a tire’s trac-
tion, temperature and treadwear. Rat-
ings are determined by tire
manufacturers using government test-

G
Rotate front and rear wheels only if they
are of the same dimension.Changing the tire dimension for an axle could cause the tire to come into contact
with the vehicle body or axle parts. Dam-
age to the tire or the vehicle may be the
result.
