308 OperationDriving tips

Attaching a trailerPlease observe the maximum permitted
trailer dimensions (width and length).
Most states and all Canadian provinces
require safety chains between your tow
vehicle and the trailer. The chains should
be crisscrossed under the trailer tongue.
They must be attached to the hitch re-
ceiver, and not to the vehicle’s bumper
or axle. Be sure to leave enough slack in
the chains to permit turning corners.
iMost states and all Canadian prov-
inces require a separate brake sys-
tem at various 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 vehi-
cle 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 damage, 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.

Warning (Continued)
G
Most states and all Canadian provinces
require 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 vehicle.You should consider using a trailer sway
control system. For further information,
see your authorized Sprinter Dealer.

Warning
G
Engine parts may be hot and can rotate.
There is a risk of injury if the hood is open
and the engine is running.
Only open the hood when the engine has
stopped and cooled down.
Warning
G
The engine has an electronic ignition sys-
tem which carries a high voltage. For this
reason, you must never touch the ignition
system components (ignition coil, test
socket) while:
\4the engine is running
\4the engine is being started
\4the key is in position2 in the ignition
lock and the engine is being cranked
by hand

counter-
clockwise to reduce excess pres-
sure.
\1
Continue turning the cap and remove
it.
\1
Add coolant as far as the MAX mark.
\1
Twist cap

back on.
For coolant specifications, see "Service
products and capacities" (
\2
page 604).
Warning
G
When opening the coolant expansion tank
there is a risk of scalding from hot coolant
spraying out. The cooling system and the
coolant expansion tank are pressurized
when the engine is at normal operating
temperature.
Wear gloves and eye protection. Only
open the coolant expansion tank when
the coolant temperature is less than
122 °F (50 °C).
Warning
G
Coolant contains glycol and is therefore
toxic. Do not swallow coolant. Consult a
doctor immediately if any coolant is swal-
lowed.
Do not allow coolant to come into contact
with your skin, eyes or clothing. In the
event of contact with the eyes, rinse them
thoroughly with clean water. Clean skin
and clothes immediately with soap and
water. Change out of soiled clothing with-
out delay.
!
CAUTION
Check the cooling and heating sys-
tems regularly for leaks. If a large
quantity of coolant is lost, have the
cause traced and rectified at an au-
thorized Sprinter Dealer.

347 Operation
Tires and wheels
4
The tire inflation pressure should be
checked regularly, i.e. at least each time
you refuel the vehicle. The preferred in-
terval for checking the tire inflation pres-
sure, however, is before each trip.
For more information on checking tire
inflation pressure, refer to "Recom-
mended tire inflation pressure"
(\2
page 361).
Tire inspectionEvery time when checking the tire infla-
tion pressure, the tires should also be in-
spected for the following:\4
excessive treadwear, refer to "Tread
depth".
\4
the condition of the tread depths, i.e.
uneven tread wear or excessive
treadwear on one side. Turn the front
wheels to full lock if necessary to en-
able you to check the inner edge of
the front tires more easily. You must
also always check the inside of the
tire tread on the rear wheels.
\4

tire’s rubber
Tire care and maintenanceWarning
G
Regularly check the tires for damage.
Damaged tires can cause tire inflation
pressure loss. As a result, you could lose
control of your vehicle.
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires have
sustained damage, replace them.
