Warning
G
You could knock yourself against the unpro-
tected pivoting frame if the seat is opposite
of the direction of travel and pushed right
back in a longitudinal direction.Therefore, center the seat above the seat
base whenever you leave it. Point out this
danger to passengers.iThe twin co-driver’s seat does not pro-
vide the same level of comfort as the
driver’s and co-driver’s seats.
There is only restricted seat width and
legroom.
iYou can store various articles in the
space under the twin co-driver’s seat.

Attaching a trailer
Please observe the maximum permitted
trailer dimensions (width and length).
Most states and all Canadian provinces re-
quire safety chains between your tow vehi-
cle and the trailer. The chains should be
crisscrossed under the trailer tongue. They
must be attached to the hitch receiver, and
not to the vehicle’s bumper or axle. Be sure
to leave enough slack in the chains to per-
mit turning corners.Towing a trailer
There are many different laws, including
speed limit restrictions, having to do with
trailer towing. Make sure that your vehicle-
trailer combination will be legal, not only
for where you reside, but also for where
you will be driving. A good source for this
information can be the police or local au-
thorities.
Before you start driving with the trailer,
check the trailer hitch, break-away switch,
safety chains, electrical connections, light-
ing and tires. Also adjust the mirrors to
permit an unobstructed view beyond the
rear of the trailer.
If the trailer has electric brakes, start your
vehicle and trailer moving slowly, and then
apply only the trailer brake controller by
hand to be sure that the brakes are work-
ing properly.
When towing a trailer, check occasionally
to be sure that the load is secure, and that
lighting and trailer brakes (if so equipped)
are functioning properly.
iMost states and all Canadian provinces
require a separate brake system at var-
ious trailer weights.
Warning
G
Do not connect a trailer brake system (if
trailer is so equipped) directly to the vehi-
cle’s hydraulic brake system as your vehicle
is equipped with antilock brakes. If you do,
neither the vehicle’s brakes nor the trailer’s
brakes will function properly. This could
cause an accident resulting in property dam-
age, injury or death to you or others.
The provided vehicle electrical wiring har-
ness for trailer towing has a brake signal
wire for hook-up to a brake controller.
Most states and all Canadian provinces re-
quire a break-away switch on trailers with a
separate brake system. The switch activates
the trailer brakes in the possible event that
the trailer might separate from the tow vehi-
cle.
You should consider using a trailer sway
control system. For further information, see
your authorized Sprinter Dealer.

3. Ride comfort and vehicle stability
Proper tire inflation contributes to a com-
fortable ride. Overinflation produces a jar-
ring and uncomfortable ride.
Besides the tire name (sales designation)
and manufacturer's name, a number of
markings can be found on a tire.
Below are some explanations regarding
the markings on your vehicle’s tires:
1DOT, Tire Identification Number (TIN)
(\2page 230)

3Maximum tire inflation pressure

Tire sizes for Sprinter vehicles
Design standard
Depending on the design standards used,
the tire size molded into the side wall may
have no letter or a letter1 preceding the
tire width or the tire load rating designa-
tion.
Letter “LT” preceding the size designation:
Light Truck tire based on U.S. design stan-
dards.
Letter “C” preceding the tire load designa-
tion:
Commercial vehicle tire based on Europe-
an design standards.
Tire width
The tire width2 indicates the nominal tire
width in mm.Aspect ratio
The aspect ratio3 is the dimensional re-
lationship between tire section height and
section width and is expressed in percent-
age. The aspect ratio is arrived at by divid-
ing section height by section width.
Tire code
The tire code4 indicates the tire con-
struction type. The “R” stands for radial
tire type. Letter “D” means diagonal or bias
ply construction; letter “B” means belted-
bias ply construction.
Rim diameter
The rim diameter5 is the diameter of the
bead seat, not the diameter of the rim
edge. Rim diameter is indicated in
inches (in).
Tire load rating
The tire load rating6 is a numerical code
associated with the maximum load a tire
can support.For example, a load rating of 120 corre-
sponds to a maximum load of 3042 lbs
(1380 kg) the tire is designed to support.
If two values are given (as illustrated), the
first value, preceding the slash "/", applies
to single tires (rear axle). The second val-
ue, succeeding the slash "/", applies to
twin tires (dual wheel rear axle).
The commercial vehicle tires based on Eu-
ropean standards may have an additional
value in the parentheses (as illustrated). In
such cases, the value preceding the paren-
theses is valid for European countries and
the parenthesized for the USA and Canada.
Refer also to "Maximum tire load"
(\2page 226) where the maximum load as-
sociated with the load index is indicated in
kilograms and lbs.

1Plies in side wall
2Plies under tread
This marking tells you about the type of
cord and number of plies in the side wall
and under the tread.Accessory weight
The combined weight (in excess of those
standard items which may be replaced) of
automatic transmission, power steering,
power brakes, power windows, power
seats, radio, and heater, to the extent that
these items are available as factory-in-
stalled equipment (whether installed or
not).
Air pressure
The amount of air inside the tire pressing
outward on each square inch of the tire.
Air pressure is expressed in pounds per
square inch (psi), or kilopascal (kPa) or
bars.
Aspect ratio
Dimensional relationship between the tire
section height and the section width ex-
pressed in percentage.Bar
Another metric unit for air pressure. There
are 14.5038 pounds per square inch (psi)
to 1 bar; there are 100 kilopascals (kPa)
to 1 bar.
Bead
The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the
rim.
Cold tire inflation pressure
Tire inflation pressure when your vehicle
has been sitting for at least 3 hours or driv-
en no more than 1 mile (1.6 km).
Curb weight
The weight of a motor vehicle with stan-
dard equipment including the maximum
capacity of fuel, oil, and coolant, and, if so
equipped, air conditioning and additional
optional equipment, but without passen-
gers and cargo.Tire ply materialiFor illustrative purposes only. The actu-
