Engine oil level indicator lamp (2)
Preheater indicator lamp (3)
WARNING!
When the engine is not running, there is no power
assistance for the brake and steering system. In
this case, it is important to keep in mind that a
considerably higher degree of effort is necessary
to brake and steer the vehicle.

136 STARTING AND OPERATING1. Apply the parking brake.
2. Automatic transmission, shift selector lever to "P"
or "N" position, refer to "Automatic Transmission".
3. Do not depress the accelerator pedal.
4. Turn the key to position 2 in the ignition lock.
The preheater indicator lampq lights up.5. Turn the key clockwise to the stop as soon as the
preheater indicator lamp
q
goes out.
If the engine is at its normal operating temperature,
the preheater indicator lamp will only light up briefly.
Release the key as soon as the engine is running.
NOTE: The key must be returned to position 0 in the
ignition lock before repeating the starting procedure.
If the displayÁ lights up alternately withî in
the multi-function display, there is an immobilizer
malfunction or the key used has not been
programmed.
The: engine oil level warning lamp and the#
battery charge warning lamp must go out after the
engine is started.
If either lamp remains on, stop the engine at once and
have the cause traced and repaired by an authorized
Sprinter Dealer.
During the trip, check the displays and the warning/
indicator lamps in the instrument cluster at regular
intervals.
For instrument cluster and indicator lamps.Maximum Engine SpeedThe maximum engine speed for all vehicles is
4,200 rpm.

174 STARTING AND OPERATING
BLEEDING DIESEL FUEL SYSTEMIf the fuel tank was run empty, the diesel fuel system
must be bled after refueling before starting the engine.– Turn the key in the ignition lock to position 2 for at
least 30 seconds.– Return the key to position 0.– Start the engine.
NOTE: Too many attempts to start the engine could
drain the battery. If the engine does not start after
several attempts, consult an authorized Sprinter
Dealer.
WARNING!
Possible tire damage resulting in serious personal
injury or death may occur if the vehicle’s electron-
ic speed controller is programmed at a speed
above the maximum speed allowed by the manu-
facturer of the specific tires mounted on the vehi-
cle. The maximum speed of the tires prescribed by
the tire manufacturer must be determined and ac-
curately programmed into the electronic speed
controller. The electronic speed controller must
never be programmed at a speed greater than the
maximum allowable tire speed as prescribed by
the manufacturer of the specific tires mounted on
the vehicle.

176 STARTING AND OPERATING Open immediately the water drain screw (3) about 1
turn (counterclockwise) until fluid emerges. Ensure
that the fluid is collected in the receptacle.
Close the water drain screw (3) as soon as about 0.25
US qt (0.2 liters) are emerged.
After draining, return the key in the ignition lock to
position 0.
Dispose of the collected fluid in an environmentally
responsible manner.
If the filter is still saturated, drain the filter once
more.
After draining, the engine may run briefly but stall for
lack of fuel. If this occurs, bleed the system.
NOTE: Should the water in the fuel indicator lamp
still not go out after the fuel filter has been drained
twice, the cause should be examined by an authorized
Sprinter Dealer.
Bleeding the Diesel Fuel SystemThe diesel fuel system is bled before starting the
engine.
Turn the key in the ignition lock position 2 for at
least 30 seconds.
Return the key to position 0.
Start the engine three to four times. The engine
control unit indicator lamp± must go out.
NOTE: Too many attempts to start the engine could
drain the battery. If the engine does not start after
several attempts, consult an authorized Sprinter
Dealer.

198 WHAT TO DO IN EMERGENCIES
Tightening torque for 9,990 lbs (4,530 kgs)
(vehicle type 3500 C/HC/SHC):
Steel wheel – 138 lbf.ft ±14 lbf.ft (190 N.m ±20 N.m)
Remove jack and stow it in the vehicle tool kit.
Check the tire pressure.
Re-tighten the wheel bolts to the specified torque
with a torque wrench after a distance of 30 miles
(about 50 km).
JUMP STA RTINGIf the battery is dead, the engine can be started with
jumper cables from another vehicle’s battery.
WARNING!
After changing a wheel, you must, for safety reasons,
have the specified tightening torque checked. The
wheels could otherwise work loose.
check the tire pressure and correct it if necessary.
retighten the wheel bolts and wheel nuts to the
specified tightening torque once the vehicle has
been driven for 30 miles (50 km).
have a reversed direction of tire rotation corrected
as soon as possible at a qualified specialist
workshop. The vehicle handling characteristics
could otherwise be affected.
WARNING!
A battery will also produce hydrogen gas, which
is flammable and very explosive. Avoid open
flames and the formation of sparks in the vicinity
of the batteries. Refrain from smoking or cell
phone use. Avoid improper connection of jumper
cables.
Observe safety precautions when handling
batteries.
Exercise care near moving engine components and
electrical cables.
Failure to follow these directions will cause
damage to the electronic components and can lead
to a battery explosion and severe injury or death.

A dead battery can freeze at a temperature of 14
°F
(–10
°C). Never try to start the engine if the battery
is frozen. Thaw the battery out first.
Only use a battery of the same rated voltage and of
approximately the same capacity for jump-starting.
The two vehicles must not touch.
Switch off all electrical accessories.
Run the vehicle with the booster battery at idle.
Connect the jumper cables in the sequence given in
the illustration. Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
clothing. In case it does, immediately flush
affected area with water, and seek medical help.
The battery housing could be damaged. Never
lean over batteries while connecting or jump-
starting. You might get injured.
Read all instructions before proceeding.
