the safety systems may no longer be able to protect you or others as they are designed to do.
Always have maintenance work carried out at a qualified specialist workshop. The qualified
specialist workshop must have the necessary specialist knowledge and tools to carry out the
work required. We recommend visiting an authorized Sprinter Dealer. In particular, work relevant
to safety or on safety-related systems must be carried out at a qualified specialist workshop. Problem Possible causes/consequences and

Tire pressure
Take note of the information on tire pressure
in the "Wheels and tires" section
(Y page 255).
G
Warning
Underinflated tires:
R jeopardize driving safety
R damage or destroy the tires
R lead to overheating of tires, even to the
point of catching fire
You could thereby lose control of the vehicle
and injure yourself and others.
For this reason, check the tire pressure
regularly before starting
a journey and correct
it if necessary.
Correct the tire pressure before loading. If the
vehicle is loaded, check the tire pressure, and
correct it if necessary. While driving, dependent on driving speeds
and
load, the

tire temperature and with it, the
tire pressure rise.
You should thus only correct tire pressures
when the tires are cold. If the tires are warm,
you may only correct tire pressures when:
R taking the respective tire temperatures into
consideration with the vehicle laden, the
values apparent from the tire pressure
table are not exceeded.
R taking the respective tire temperatures into
consideration with the vehicle unladen, the
values apparent from the tire pressure
table are not met.
The tires are considered cold if the vehicle has
been parked for at least 3 hours or been
driven less than 1 mile (1.6 km) with an
outside temperature of about 68 ‡ (20 †).
i The tire pressure changes by
approximately 10 kPa (0.1 bar/1.5 psi) per
