This will prevent excessive wear and possi-
ble engine failure.
If the brake system is defective, braking
behaviour may change or the brake system
may fail. If you notice a reduction in braking
power when testing the brakes, stop the vehi-
cle as soon as possible while paying attention
to traffic conditions. Have the brake system
checked and repaired at a qualified specialist
workshop.
You should pay special attention to road con-
ditions when temperatures are around the
freezing point.
i If you increase the idling speed
(
Y
page 114), this eases pulling away on
uphill gradients.
X Change gear or select a shift range; see
Transmission shift system (
Y
page 110).
X
Release the brake pedal or parking brake
and slowly depress the accelerator pedal.
Only select reverse gear at idling speed and
when the vehicle is stationary.
X When starting a journey, carry out a brake
test. Observe the road and traffic conditions
when doing so.
Do not judge when to change gear by the
sound of the engine. The engine speed should
always remain within the green zone of the rev
counter where possible.
Warm up the engine quickly by driving at mod-
erate engine speeds. After approximately 10
to 20 minutes the engine will reach its operat-
ing temperature of between approximately 70
and 98 †, depending on the outside tempera-
ture.
You can utilise the full engine power output
once the engine has reached normal operating
temperature.
Stopping and switching off the
engine

WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact
with hot parts of the exhaust system or
exhaust gas flow. There is a risk of fire.
Park the vehicle so that no flammable mate-
rial can come into contact with hot vehicle
components. In particular, do not park on
dry grassland or harvested grain fields.
X
Stop the vehicle.
X
Apply the parking brake.
X Shift into neutral.
Let the engine idle for approximately
2 minutes before switching it off if:
R
the coolant temperature is very high (over
90 †).
R
the full engine power has been used, e.g.
while driving in mountainous terrain.
X To switch off the engine: turn the key in
the ignition lock back fully.
X
Safeguard the vehicle against rolling away;
use chocks if necessary.
Wheel chocks may only be used on the non-
steered axle of the vehicle.
i When you switch off the engine, BlueTEC
®
exhaust gas aftertreatment automatically
flushes the exhaust system with fresh air.
Residues of AdBlue
®
on the metering unit or
the injection nozzle might otherwise impair
the function of BlueTEC
®
exhaust gas after-
treatment. Depending on the vehicle's previ-
ous operating load, BlueTEC
®
exhaust gas
aftertreatment may flush the exhaust sys-
tem several times.
When BlueTEC
®
exhaust gas aftertreatment
flushes the exhaust system, an vent valve is
activated. You may then hear a hissing
sound. This hissing sound does not indicate
a leak in the compressed-air system.
Brakes
Introduction
If the display shows a display message and the
status indicator lights up red, the braking char-
acteristics of the vehicle have changed. Do not
then pull away. If you pull away, stop as soon
as possible, taking the traffic situation into
account. The pedal travel and pedal force
required to brake the vehicle or the vehicle
combination may increase. Have the brake
system checked at a qualified specialist work-
shop.
Always pay attention to the display messages.
