Always ensure that you re-calibrate the
TPMS after you inflated the tires to the
recommended cold inflation pressure.Always adjust tire inflation pressure ac-
cording to the tire and loading information
placard on the driver’s door B-pillar.Underinflated tires wear excessively and/
or unevenly, adversely affect handling and
fuel economy, and are more likely to fail
from being overheated.
Continued
Warning (Continued)
G
Overinflated tires can adversely affect
handling and ride comfort, wear unevenly,
increase stopping distance, and result in
sudden deflation (blowout) because they
are more likely to become punctured or
damaged by road debris, potholes etc.The TPMS is not able to issue a warning
due to a sudden dramatic loss of pressure
(e.g. tire blowout caused by a foreign ob-
ject). In this case bring the vehicle to a
halt by carefully applying the brakes and
avoiding abrupt steering maneuvers.
Warning
G
Each tire, including the spare (if provided),
should be checked monthly when cold
and inflated to the inflation pressure rec-
ommended by the vehicle manufacturer
on the tire and loading information plac-
ard. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or the tire inflation pressure label,
you should determine the proper tire infla-
tion pressure for those tires).

Press the ,menu button on the in-
strument cluster.
The following message is displayed:OK TPMSThe tire pressure monitor activation
process has begun.
The tire pressures of the individual
wheels are stored as the new refer-
ence values if they are determined to
be plausible for the tire pressure
monitor.If you wish to cancel the activation pro-
cess:

Press the .button or the 5menu but-
ton on the instrument cluster.
The activation process is canceled
automatically if 30 seconds elapse
with no input.
Checking tire inflation pressure elec-
tronically with the Tire Pressure Mon-
itoring System (TPMS)* (vehicles
with steering wheel buttons)Vehicles with steering wheel buttons are
equipped with the Advanced Tire Pres-
sure Monitoring System.
iUSA only:
The Tire Pressure Monitoring System
(TPMS) is equipped with a combina-
tion low tire pressure/TPMS mal-
function telltale in the instrument
cluster (
\2
page 20). Depending on
how the telltale illuminates, it indi-
cates a low tire pressure condition or
a malfunction in the TPMS system it-
self:
If the telltale illuminates continuous-
ly, one or more of your tires is signif-
icantly underinflated. There is no
malfunction in the TPMS.

Warning
G
The TPMS does not warn you against in-
correctly selected tire inflation pressure
and does not warn you when the tire pres-
sure is not properly selected for the re-
spective vehicle load. It warns you only
when the pressure of one or more tires
decreases significantly below the refer-
ence inflation pressure which was stored
at the time of calibration of the TPMS af-
ter you inflated the tires.Always ensure that you recalibrate the
TPMS after you have inflated the tires to
the recommended cold inflation pressure.

Potential problems associated with
underinflated and overinflated tiresProper tire inflation pressure is essential
to the safe and satisfactory operation of
your vehicle. The following three primary
areas are affected by improper tire infla-
tion pressure:

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

Tires on the front and rear axles of vehi-
cles operate at different loads and per-
form different steering, driving and
braking functions. For these reasons,
they wear at unequal rates, and develop
irregular wear patterns. These effects
can be reduced by timely rotation of
tires.
The benefits of rotation are especially
worthwhile with aggressive tread de-
signs such as those on On/Off Road
type tires. Rotation will increase tread
life, help to maintain mud, snow, and wet
traction levels, and contribute to a
smooth ride. If applicable to your vehicle’s tire config-
uration, tires can be rotated according
to the tire manufacturer’s recommend-
ed intervals in the tire manufacturer’s
warranty pamphlet located in your vehi-
cle literature portfolio. If none is avail-
able, tires should be rotated every
10 000 miles (16 000 km), or sooner if
necessary, according to the degree of
tire wear.
The same rotation (spinning) direction
must be maintained when mounted, see
"Direction of rotation" (
\2
page 351).
Warning (Continued)
G
could result in changes to steering, han-
dling, and braking of your Sprinter vehicle.
This can cause unpredictable handling
and stress to steering and suspension
components. You could lose control and
have an accident resulting in serious inju-
ry or death.could result in tire overloading and failure,
if the tires' load index are not identical.
You could lose control and have an acci-
dent.
