Driving and operating161AdBlue
General information
The selective catalytic reduction
(BlueInjection) is a method to
substantially reduce the nitrogen
oxides in the exhaust emission. This
is achieved by injecting a Diesel
Exhaust Fluid (DEF) into the exhaust
system. The ammonia released by
the fluid reacts with nitrous gases
(NO x) from the exhaust and turns it
into nitrogen and water.
The designation of this fluid is
AdBlue ®
. It is a non-toxic, non-
flammable, colourless and odourless
fluid which consists of 32% urea and
68% water.9 Warning
Avoid contact of your eyes or skin
with AdBlue.
In case of eye or skin contact,
rinse off with water.
Caution
Avoid contact of the paintwork with AdBlue.
In case of contact, rinse off with water.
AdBlue freezes at a temperature of
approx. -11 °C. As the vehicle is
equipped with an AdBlue pre-heater,
the emissions reduction at low
temperatures is ensured. The AdBlue
pre-heater works automatically.
The typical AdBlue consumption is
approx. 22 l per 6000 miles to
9000 miles depending on driving behaviour (e.g. high load or towing).
Level warnings
Depending on the calculated range of
AdBlue, different messages are
displayed in the Driver Information
Centre. The messages and the
restrictions are a legal requirement.
1. The first possible warning is Top
up emissions additive: Starting
prevented in 1500 mi .
When switching on the ignition,
this warning will show up once
briefly with the calculated range.
Additionally, control indicator
B will illuminate and a chime
will sound. Driving is possible
without any restrictions.
2. The next warning level is entered with a range below 500 miles. Themessage with the current range
will always be displayed when
ignition is switched on.
Additionally, control indicator
B will illuminate and a chime
will sound. Refill AdBlue before
entering the next warning level.
When driving, the chime sounds
and the message is displayed
every 60 miles until the AdBlue
tank has been topped-up.
3. The next warning level is entered with a range below 60 miles. The
message with the current range
will always be displayed when
ignition is switched on.
Additionally, control indicator
B will flash and a chime will
sound. Refill AdBlue as soon as
possible before the AdBlue tank is
162Driving and operatingcompletely empty. Otherwise, a
restart of the engine will not be
possible.
When driving, the chime sounds
and the message is displayed
every 6 miles until the AdBlue tank
has been topped-up.
4. The last warning level is entered when the AdBlue tank is empty.
Restart of the engine is not
possible. The following warning
message will be displayed:
Top up emissions additive:
Starting prevented
Additionally, control indicator
B will flash and a chime will
sound.
Refill the tank to a level of at least 5 l of AdBlue, otherwise restarting
of the engine is not possible.
Notice
Depending on the engine different
levels may apply.
High emission warnings
In the event of a fault with the
emissions control system, different
messages are displayed in the DriverInformation Centre. The messages
and the restrictions are a legal
requirement.
1. If a fault is detected for the first time, the warning Emissions fault
is displayed.
Additionally, control indicators
B , C and W will illuminate
and a chime will sound. Driving is
possible without any restrictions.
If it is a temporary fault, the alert
disappears during the next
journey, after self-diagnosis of the
emissions control system.
2. If the fault is confirmed by the emission control system, the
following message will be
displayed:
Emissions fault: Starting
prevented in 650 miles .
Additionally, control indicators
B , C and W will illuminate
and a chime will sound.When driving, the message is
displayed every 30 s while the
fault persists.
3. If the last warning level is entered,
the following warning message
will be displayed:
Emissions fault: Startingprevented
Additionally, control indicators
B , C and W will illuminate
and a chime will sound.
Consult a workshop for
assistance.
Refilling AdBlueCaution
Only use AdBlue that complies
with European standards
DIN 70 070 and ISO 22241-1.
Do not use additives.
Do not dilute AdBlue.
Otherwise the selective catalytic
reduction system could be
damaged.
Driving and operating167In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions.
Gear shift indication
The symbol Y or Z with a number
beside it is indicated when
gearshifting is recommended for fuel
saving reasons.
Shift indication appears only in
manual mode.
Electronic driving programmes
● Following a cold start, the operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● Special programmes automatically adapt the shifting
points when driving up inclines or
down hills.
● In snowy or icy conditions or on other slippery surfaces, the
electronic transmission controlenables the driver to select
manually first, second or third gear for starting off.
Kickdown
Pressing down the accelerator pedal
beyond the kickdown detent will lead to maximum acceleration
independent of selected driving
mode. The transmission shifts to a
lower gear depending on engine speed.
Fault
In the event of a fault a message is
displayed in the Driver Information
Centre.
Vehicle messages 3 122.
Electronic transmission control
enables only third gear. The
transmission no longer shifts
automatically.
Do not drive faster than 62 mph.
Have the cause of the fault remedied by a workshop.Manual transmission
To engage reverse on 5-speed
transmission, depress the clutch
pedal and move the selector lever to
the right and rear.
Driving and operating169ABS starts to regulate brake pressure
as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
When braking in an emergency, the
hazard warning flashers are switched on automatically depending on the
force of deceleration. They are
switched off automatically the first
time you accelerate.
After starting off, the system performs
a self-test which may be audible.
Control indicator i 3 111.
Fault9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake
9 Warning
Always apply parking brake firmly
without operating the release
button, and apply as firmly as
possible on a downhill or uphill
slope.
To release the parking brake, pull
the lever up slightly, press the
release button and fully lower the
lever.
To reduce the operating forces of
the parking brake, depress the
foot brake at the same time.
Brake assist
If brake pedal is depressed quickly
and forcefully, maximum brake force
is automatically applied.
Operation of brake assist might
become apparent by a pulse in the
brake pedal and a greater resistance
when depressing the brake pedal.
Maintain steady pressure on the
brake pedal as long as full braking is
required. Maximum brake force is
automatically reduced when brake
pedal is released.
170Driving and operatingHill start assistThe system helps prevent unintendedmovement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline, brakes remain
on for further 2 seconds. The brakes
release automatically as soon as the
vehicle begins to accelerate.Ride control systems
Electronic Stability Control and Traction Control system
Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip.
As soon as the vehicle starts to
swerve (understeer / oversteer),
engine output is reduced and the
wheels are braked individually.
ESC operates in combination with the Traction Control system (TC). It
prevents the driven wheels from
spinning.
The TC is a component of the ESC.
Traction Control improves driving
stability when necessary, regardless
of the type of road surface or tyre grip,
by preventing the driven wheels from
spinning.
As soon as the driven wheels starts to spin, engine output is reduced and
the wheel spinning the most is brakedindividually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
ESC and TC are operational after
each engine start as soon as the
control indicator J extinguishes.
When ESC and TC operate, J
flashes.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Control indicator J 3 112.
Driving and operating171Deactivation
ESC and TC can be deactivated,
everytime it is required: press 9.
The LED in the button 9 illuminates.
A status message appears in the
Driver Information Centre when ESC
and TC are deactivated.
ESC and TC are reactivated by
pressing the 9 button again or in the
case that the vehicle is driven faster
than 30 mph.
The LED in the button 9 extinguishes
when ESC and TC are reactivated.
ESC and TC are also reactivated the
next time the ignition is switched on.
Fault
If there is a fault in the system, the control indicator J illuminates
continuously and a message appears
in the Driver Information Centre. The
system is not operational.
Have the cause of the fault remedied
by a workshop.
Selective ride controlCaution
The vehicle is designed to drive
principally on-road, but it also
enables driving off-road
occasionally.
However, do not drive on terrain
where the vehicle could be
damaged due to obstacles, such
as rocks among others and on
terrain with steep inclines and
poor grip.
Do not cross waters.
Caution
When driving off-road, sudden
motion and manoeuvres can
cause a collision or losing control.
Selective ride control is designed to
optimise traction in low-grip
conditions (snow, mud and sand).
It adapts to the terrain by acting on the
front wheels, in doing so this saves
the weight normally associated with a more conventional four wheel drive
system.
172Driving and operatingSelective ride control allows to
choose between five driving modes:
● ESC off mode 9
● standard mode 2
● snow mode 3
● mud mode 4
● sand mode 1
The several modes can be activated
by turning the control.
An LED illuminates and a status
message appears in the Driver
Information Centre to confirm the
chosen mode.
ESC off mode 9
The ESC and Traction Control are
deactivated in this mode.
An LED in the button 9 illuminates.
ESC and Traction Control are
reactivated automatically from
30 mph or everytime the ignition is
switched on.Standard mode 2
This mode is calibrated for a low level of wheel spin, based on the differenttypes of grip generally encountered in
normal day to day driving.
Everytime the ignition is switched off,
the system is automatically reset to
this mode.
Snow mode 3
This mode adapts to the grip
conditions encountered by each
wheel when starting.
When advancing, the system
optimises wheel spin to guarantee the
best acceleration based on the
available traction. Recommended in
cases of deep snow and steep
inclines.
This mode is active up to a speed of
30 mph.
Mud mode 4
This mode allows considerable wheel
spin at start-up for the wheel with the
least grip, this removes mud and re-
establishes traction.Simultaneously, the wheel with the
most grip is provided with the most
torque possible.
This mode is active up to a speed of 50 mph.
Sand mode 1
This mode allows a small amount of
simultaneous wheel spin on the two drive wheels, enabling the vehicle to
advance and reduce the risk of
sinking.
This mode is active up to a speed of
75 mph.Caution
Do not use the other modes on
sand as the vehicle may become
stuck.
Driving and operating173Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The cruise control can store and
maintain speeds above 25 mph.
Additionally at least the third gear
must be engaged on manual
transmission, on automatic
transmission position D / A or the
second or a higher gear in position
M must be selected.
Deviations from the stored speeds
may occur when driving uphill or
downhill.
The system maintains the vehicle
speed at the preset speed by the
driver, without any action on the
accelerator pedal.
The preset speed can be exceeded
temporarily by pressing the
accelerator pedal firmly.
The status and preset speed is
displayed in the Driver Information
Centre.
Do not use the cruise control if it is not advisable to maintain a constant
speed.
