MTU 4R 1000 SERIES, Operating Instructions Manual

Page: 49 / 88

R
do not shift down to brake the vehicle.
R
for vehicles with automatic transmission,
do not depress the accelerator pedal
beyond the point of resistance (kickdown).
After 2,000 km (30 operating hours), you can
gradually bring the vehicle/equipment up to
full output and increased engine speeds.
Fuel consumption
General notes
Fuel consumption depends on:
R
the machine version/vehicle version
R
the operating conditions
R
the attached equipment (e.g. hydraulic
pumps, mowers, etc.)
R
maintenance
R
driving resistance
R
your driving style
For these reasons, exact details about any
single engine's fuel consumption cannot be
provided.
Machine version/vehicle version
The following components affect fuel con-
sumption:
R
tyres (e.g. tyre pressure, tyre condition)
R
body type
R
drive train (e.g. transmission ratio)
R
additional equipment (e.g. automatic cli-
mate control, auxiliary heating)
Maintenance
Fuel consumption and assembly wear depend
on how often maintenance is carried out. Reg-
ular maintenance increases safety and lowers
fuel consumption. Keep to the maintenance
intervals. Always have maintenance work car-
ried out at a qualified specialist workshop.
Fuel type
The fuel grade also affects fuel consumption.
Use of lower fuel grades and/or non-
approved fuel additives will increase fuel con-
sumption. When refuelling, ensure that you
are filling the appropriate fuel grade
(

page 56).
AdBlue
®
/DEF consumption
AdBlue
®
consumption is between 2 and 4% of
the fuel consumption, depending on engine
use.
Engine oil consumption
After running-in the engine, oil consumption
may reach 0.2% of the vehicle's fuel con-
sumption.
More arduous operating conditions and
increased distance covered could result in
engines exceeding this oil consumption
value.
Warning buzzer
If the warning buzzer sounds and the
5
symbol on the instrument panel is displayed,
the engine's operating safety is jeopardised.
Do not pull away, or stop the vehicle as soon
as possible, paying attention to road and traf-
fic conditions. You could otherwise damage
the engine.
The warning buzzer sounds depending on the
vehicle if:
R
you exceed the maximum permissible
engine speed.
R
the engine speed or vehicle speed is too
high when changing gears.
R
the coolant level is too low or the maximum
permissible coolant temperature
