Driving tips

Always secure items in the trailer to pre-
vent load shifts while driving.
Take into consideration that when towing a
trailer, the handling characteristics are dif-
ferent and less stable from those when op-
erating the vehicle without a trailer. It is
important to avoid sudden maneuvers.
The vehicle and trailer combination is
heavier, and therefore is limited in acceler-
ation and climbing ability, and requires
longer stopping distances. It is more prone
to reacting to side wind gusts, and requires
more sensitive steering input.
In order to gain skill and an understanding
of the vehicle’s behavior, you should prac-
tice turning , st opping and backing up in a n
area which is free from traffic.
If possible, do not brake abruptly, but rath-
er engage the brake slightly at first to per-
mit the trailer to activate its brake. Then
increase the braking force.
Warning
G
Take into consideration that when towing a
trailer, the handling characteristics are dif-
ferent and less stable from those when op-
erating the vehicle without a trailer.
It is important to avoid sudden maneuvers.
Sudden maneuvers may lead to loss of con-
trol over the vehicle-trailer combination.
This could cause an accident resulting in
property damage or injury to you or others.!
CAUTION
If the transmission hunts between
gears on inclines, manually shift to a
lower gear (select
"4", "3", "2" or
"1").
A lower gear and reduction of speed re-
duces the chance of the engine over-
loading and / or overheating.
When going down a long hill, shift into
a lower gear and use the engine’s brak-
ing effect. Avoid riding the brakes, thus
overheating the vehicle and trailer
brakes.
If the engine coolant rises to an ex-
tremely high temperature (coolant tem-
perature needle approaching the red
zone) when the air conditioner is on,
turn off the air conditioner. Engine
coolant heat can be additionally vented
by opening the windows, switching the
climate control fan speed to high and
setting the temperature control to the
maximum hot position.
Extreme care must be exercised since
your vehicle with a trailer will require
additional passing distance ahead than
when driving without a trailer. Because
your vehicle and trailer is longer than
your vehicle alone, you will also need to
go much farther ahead of the passed
vehicle before you can return to your
lane.

Any noticeable irregularities in engine

Tires and wheels

Cuts and punctures in radial tires are re-
pairable only in the tread area because of
side wall flexing. Consult an authorized tire
dealer for radial tire repairs.\4Only use sets of tires and rims of the
same type and make.
\4Tires must be of the correct size for the
rim.
\4Break in new tires for approximately
65 miles (100 km) at moderate
speeds.
\4Regularly check the tires and rims for
damage. Dented or bent rims can
cause tire inflation pressure loss or
damage to the tire beads.
\4If the vehicle is heavily loaded, check
tire inflation pressure and correct as
required.
\4Do not allow your tires to wear down
too far. Adhesion properties on wet
roads are sharply reduced at tread
depths under
1/8in (3 mm) for sum-
mer tires and
1/6in (4 mm) for winter
tires.
Radial-ply tiresWarning
G
Combining radial ply tires with other types
of tires on your Sprinter vehicle will change
the vehicle’s handling characteristics and
may lead to an accident resulting in death,
severe personal injuries and property dam-
age. Always use radial ply tires in sets of 4
(or 6, in case of vehicles with dual rear
wheels).
Never combine them with other types of
tires.
Tire valves (snap-in valves)Warning
G
Sprinter tire valves are tested and approved
under rough operating conditions.
The installation of additional hub caps or
other wheel simulators could cause damage
to the tire valve and lead to a loss of tire
pressure at the valve stem.
Do not install any of these parts on your
Sprinter vehicle. To help ensure safe and re-
liable operation of your Sprinter vehicle,
only use parts and accessories tested and
approved by the vehicle manufacturer for
your Sprinter vehicle.!
CAUTION
For safety reasons, the following tire
valves from the Schrader company
must be used on the vehicles:
\4TR 600 for vehicle model type 2500
\4TR 418 for vehicle model type 3500
Other tire valves could be damaged by
the specified tire pressures.Important guidelines

The placard lists the recommended cold
tire inflation pressures for all load conditi-
ons up to the maximum permissible weight
limits (GAWR). The tire inflation pressures
listed apply to the tires installed as original
equipment.
Important notes on tire inflation pres-
sure
Tire temperature and tire inflation pressure
are also increased while driving, depending
on the driving speed and the tire load.
Tire inflation pressure changes by approxi-
mately 1.5 psi (0.1 bar) per 18 °F (10 °C)
of air temperature change. Keep this in mind when checking tire inflation pressure
where the temperature is different from
the outside temperature.
For example:
If the inside temperature is 68 °F (20 °C)
and the outside temperature is 32 °F
(0 °C) then the cold tire inflation pressure
should be increased by 3 psi (0.2 bar),
which equals 1.5 psi (0.1 bar) for every
18 °F (10 °C) for this outside temperature
condition.
Check tire pressures more often if subject
to a wide range of outdoor temperatures,
as tire pressures vary with temperature
changes.Warning
G
If the tire inflation pressure repeatedly
drops:
\4Check the tires for punctures from for-
eign objects.
\4Check to see whether air is leaking from
the valves or from around the rim.
Warning
G
Tire pressure may increase during opera-
tion.
Never reduce this normal pressure build up
or your tire pressure will be too low.
Underinflated tires wear excessively and/or
unevenly, adversely affect handling and fuel
economy, and are more likely to fail from be-
ing overheated.
