Screw in the wheel bolts and tighten
them finger-tight.

CAUTION
If your vehicle is equipped with the
tire pressure monitor, each wheel
has an electronic component.
Tire mounting tools should not be ap-
plied in the area of the valve, as this
could damage the electronic compo-
nents.
Have the tires changed only at an
authorized Sprinter Dealer.
Warning
G
Do not tighten the wheel bolts and wheel
nuts completely while the vehicle is still
jacked up. The vehicle could tip.
iOn vehicles with light-alloy wheels,
you will find short wheel bolts suit-
able for the steel spare wheel in the
vehicle tool kit.N40.10-2175-31

Vehicles with wheel caps:
Make sure that the opening in the
wheel cap is positioned over the tire
vent.
Vehicles with center caps:
Make sure that the retaining lugs of
the hub cap are positioned over the
bolts.
\1
Compress the piston of the hydraulic
jack and close the pressure release
screw.
\1
Store the jack and the remaining ve-
hicle tools.
\1
Place the defective wheel in the
spare wheel bracket after changing
the wheel (
\2
page 517).
\1
Check the tire pressure
(\2
page 361).
\1
Retighten the wheel bolts and wheel
nuts to the specified tightening
torque once the vehicle has been
driven for 30 miles (50 km).
iGive the middle of the center cap a
knock to engage it on the wheel.
Warning
G
For safety reasons, you must observe the
following after changing a wheel:Have the tightening torque checked:for wheel bolts 177 lb-ft (240 Nm) (steel
wheel)/133 lb-ft (180 Nm) (light-alloy
wheel) orfor wheel nuts133 lb-ft (180 Nm).The wheels could otherwise come loose.

G
Check the tire pressure and correct it if
necessaryHave the wheel bolts or wheel nuts re-
tightened after 30 miles (50 km) to a
torque of:177 lb-ft (240 Nm) (steel wheel)/ 133 lb-
ft (180 Nm) (light-alloy wheel) for wheel
bolts or133 lb-ft (180 Nm) for wheel nuts.

Warning (Continued)
G
Have the direction of tire rotation correct-
ed, if reversed, as soon as possible at an
authorized Sprinter Dealer. The vehicle
handling characteristics could otherwise
be affected.
Warning
G
Loose wheel nuts or bolts could cause the
vehicle to lose a wheel while it is in mo-
tion. This would jeopardize the operating
and road safety of the vehicle. You could
lose control of the vehicle as a result,
cause an accident and injure yourself or
others.
If new or repainted wheels are mounted,
the wheel bolts or wheel nuts must be re-
tightened again after approximately 600
to 3000 miles (about 1000 to 5000 km).

You can use the Premium tire sealant to
seal small punctures, particularly those
in the tire tread. Tire sealants can be
used at outside temperatures down to –
22 °F (–30 °C).
Prepare the vehicle as described
(\2
page 548).Using Premium tire sealant*Warning
G
Smoking, fire and naked flames are pro-
hibited when handling Premium tire seal-
ant.
Avoid creating sparks.
Warning
G
Your safety is at particular risk and the
tire sealant is unable to repair a tire in the
following situations:if there are cuts or punctures in the tire
greater than 0.23 in (6 mm)if the rim is damagedif you have driven with very low tire pres-
sures or with flat tires

Do not drive any further. Consult an au-
thorized Sprinter Dealer which has the
necessary specialist knowledge and tools
to carry out the work required.The manufacturer recommends that you
use an authorized Sprinter Dealer for this
purpose. In particular, work relevant to
safety or on safety-related systems must
be carried out at an authorized Sprinter
Dealer.

Try to park the vehicle in such a way
that the tire puncture is close to the
ground. If the tire puncture cannot
be seen, park the vehicle in such a
way that the tire valve of the flat tire
is in horizontal alignment with the ax-
le.
\1
It is beneficial to the sealing process
if you remove the foreign body that
has pierced the tire, for example the
screw or nail.
\1
Remove the Premium tire sealant,
the accompanying "max. 50 mph
(80 km/h)" sticker and the electric
air pump from the storage compart-
ment in the right-hand doorway
(\2
page 521).
\1
Affix the sticker within the driver’s
field of vision.
!
CAUTION
Only connect the electric air pump to
the 12 V socket (
\2
page 297) on the
center console (12 V, 25 A,
300 watts). You could otherwise
damage the vehicle electrical sys-
tem.
Warning
G
Comply with the manufacturer’s safety in-
structions as seen on the sticker on the elec-
tric air pump and the tire sealant bottle.Warning
G
Tire sealant must not come into contact
with your skin, eyes or clothing.If tire sealant comes into contact with
your eyes or skin, immediately rinse thor-
oughly with clean water.
