132Driving and operatingIf AdBlue is not refilled within a certaindistance, further level warnings are
shown in the Driver Information
Centre, depending on the current
AdBlue level.
Subsequent requests to refill AdBlue
and finally the announcement that an engine restart will be prevented are
displayed in the Driver Information
Centre.
Note
These restrictions are a legal
requirement.At an AdBlue range of 900 km, the following warning messages are
alternately displayed in the Driver
Information Centre:
● AdBlue Low Refill Now
● Engine Restart Prevented in
900 km
Additionally, control indicator Y
flashes continuously.
Engine restarts prevented
Before the prevention of an engine
restart, the following warning
messages are alternately displayed in the Driver Information Centre:
● AdBlue Empty Refill Now
● Engine Will Not Restart
These messages indicate that after
switching off the ignition, an engine
restart will be prohibited.
Additionally, control indicator Y
flashes continuously.
After the prevention of an engine
start, a warning message (e.g. "Refill
AdBlue To Start Vehicle") is displayed
in the Driver Information Centre
reminding the driver that AdBlue level
is insufficient.
To allow the engine to be restarted,
the tank should be filled with at least
10 litres of AdBlue.
High emission warningsIf the exhaust emission rises above a
certain value, warnings similar to the
range warnings as described above
will be displayed in the Driver
Information Centre.
Requests to have the exhaust system checked and finally the
announcement that an engine restart
will be prevented are displayed in the
Driver Information Centre.
Driving and operating133Note
These restrictions are a legal
requirement.
Seek the assistance of a workshop as
soon as possible.
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.
Note
If AdBlue must be refilled at very low temperatures, the refilling of AdBlue
may not be detected by the system.
In this case, park the vehicle in a
space with a higher ambient
temperature until AdBlue is
liquefied.
Note
If engine starting is prohibited due to low AdBlue level, we recommend
refilling the tank completely or with a volume of at least ten litres of AdBlue(depending on AdBlue
consumption).
Avoid minor top-ups (e.g. less than five litres), otherwise the system
may not detect a refill.
Note
When unscrewing the protective cap
from the filler neck, ammonia fumes
may emerge. Do not inhale as the
fumes have a pungent smell. The
fumes are not harmful by inhalation.
The vehicle must be parked on a level surface.
The filler neck for AdBlue is located at
the rear bumper on the left-hand side of the vehicle.9 Danger
Vehicles with stop-start system:
The engine must be switched off
and the ignition key removed, to
avoid risk of engine being
restarted automatically by the
system.
Capacities 3 211.
134Driving and operatingFilling station9Danger
Follow the operating and safety
instructions of the filling station
when refilling AdBlue.
1. Switch off engine and remove key
from ignition switch.
2. Disengage the cover using a suitable screwdriver and remove.
3. Unscrew protective capanticlockwise from the filler neck.
4. Fully insert the pump nozzle intothe filler neck and switch it on.
5. When refilling is complete, mount the protective cap and turn
clockwise until it engages.
6. Replace the cover by inserting the
right side first.
AdBlue canister Note
Only use the designated AdBlue
canisters for refilling, to prevent a
topping-up of too much AdBlue.
Additionally, the fumes in the tank
are captured in the canister and do
not emerge.
Note
Since AdBlue has a limited
durability, check the date of expiry
before refilling.
1. Switch off engine and remove key
from ignition switch.
2. Disengage the cover using a suitable screwdriver and remove.
3. Unscrew protective cap anticlockwise from the filler neck.
136Driving and operatingAutomatic transmission
The automatic transmission permits
automatic gearshifting (automatic
mode) or manual gearshifting
(manual mode).

Never shift to P or R while the vehicle
is moving.
The engine can only be started with
lever in position P or N. Depress foot
brake or apply electrical parking
brake before starting.
Do not accelerate while engaging a
gear. Never depress the accelerator
pedal and brake pedal at the same
time.
When a gear is engaged, the vehicle
slowly begins to creep when the foot
brake is released.
Engine braking To utilise the engine braking effect,
select a lower gear in good time when
driving downhill - see Manual mode.
Driving and operating137Use of the engine braking effect, as
opposed to the use of the foot brake
when driving downhill, can extend the
life of the brakes.
Rocking the vehicle
Rocking the vehicle is only
permissible if the vehicle is stuck in
water, ice, sand, mud, snow or a dip.
Move the selector lever between D
and R in a repeat pattern while
applying light pressure to the
accelerator pedal when the vehicle is in gear. Do not race the engine and
avoid sudden acceleration.
If the vehicle cannot be released after
rocking the vehicle several times,
your vehicle may need to be towed
3 196.
Parking Apply the electrical parking brake and
engage P.
The ignition key can only be removed
when the selector lever is in position
P .Sport mode
Suspension and steering become
more direct and provide better
contact with the road surface. The
engine reacts more quickly to
accelerator pedal movements.
Automatic gear changing is also more
responsive.
Sport mode can reduce the vehicle's
fuel economy. Use normal mode whenever possible.
Note
Sport mode may be unavailable if the charging level of the vehicle
battery is too low.
ActivationPress SPORT to switch on Sport
mode.
Control indicator S illuminates in
the instrument cluster 3 86.
Deactivation
Press SPORT again to return to
normal mode. Control indicator S extinguishes.
Driving and operating139Interruption of power supplyThe clutch is not disengaged if the
vehicle battery is discharged and a
gear has been selected. The vehicle
cannot move. The selector lever
cannot be moved out of position P or
N .
If the battery is discharged, start the
vehicle using jump leads 3 194.
If the battery is not the cause of the
fault, release the selector lever:
1. Switch off ignition and remove the
key.
2. Depress and hold foot brake.
3. Remove trim cover.
4. Press and hold shift lock release button.
5. Shift to neutral ( N).
6. Replace trim cover.
7. Start engine and shift to chosen gear.
Have the cause of the power supply
interruption remedied by a workshop.
Manual transmission
To engage reverse, with the vehicle
stationary, wait 3 seconds after
depressing clutch pedal and engage
the gear.
If the gear does not engage, set the
lever to neutral, release the clutch
pedal and depress again; then repeat
gear selection.
Do not slip the clutch unnecessarily.
When operating, depress the clutch
pedal completely. Do not use the
pedal as a foot rest.
Driving and operating141you might in a conventional vehicle.
Strong crosswinds can affect the
normal steering of the vehicle. Drive
slower under strong crosswind
conditions.
Off-road driving ● Avoid protruding objects (such as
rocks or tree stumps) that may
damage the underbody and tyres of your vehicle.
● Test the brakes after operating in
mud, to clear excess mud from
the braking surfaces.
● Grip the steering wheel when travelling over rough terrain.
Terrain conditions can cause
rapid and unexpected movement in the steering.
The ground clearance, ramp angle,
angle of approach and departure and wading depth need to be considered,
especially in hilly conditions and
when wading, to prevent the vehicle
becoming stuck and possibly
damaged.
Vehicle dimensions 3 209.
Towing the vehicle 3 196.Driving through water
Do not exceed the maximum wading
depth 3 209.
Check the depth of water: choose the
lowest entry and departure angles
before entering. Maintain a steady
engine speed, to help prevent water
from entering the exhaust system, but do not exceed 5 km/h, to avoid
splashing the water.
Drive with the flow wherever possible,
not against it. If you have to drive
against the flow, try to drive at an
angle to it, so that the leading corner
of the vehicle will help deflect water
from the engine compartment. Avoid
splashing the water - if the ignition
system becomes wet, the engine may
stall.
Avoid water entering the air intake
system 3 120. If water enters the air
intake system, engine seizure with severe costly damage may result.
Test the brakes after leaving the
water - wet brakes are less effective
than dry ones. Perform the service
operations for wading , involving
checks for water contamination, at
the earliest opportunity.Service checks after wading
Check for the ingress of water into the following:
● Brake fluid reservoir
● Air cleaner element
● Engine
● Transmission
● Axles
● Interior of vehicle
Renew any lubricating oil or hydraulic
fluid that has a milky appearance,
indicating contamination with water.
Cleaning
Clean the vehicle thoroughly and as
soon as possible after driving off-
road.
Do not let mud remain dry on any part
of the vehicle as it becomes abrasive and can damage paint, glass, seals,
bearings and brake components. If
left to build up, mud can seriously
affect the airflow through and over
mechanical components and cause
localised overheating and failure of
parts, especially in the engine
compartment.
Driving and operating143ABS 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.
After starting off, the system performs a self-test which may be audible.
Control indicator u 3 85.
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 nolonger be steered and may
swerve.
You can continue driving, provided
you drive with care and anticipation.
Have the cause of the fault remedied
by a workshop.
Parking brake
Electrical parking brake
Applying when vehicle is stationary
Pull switch m, the electrical parking
brake operates automatically with
adequate force. For maximum force,
e.g. parking with a trailer or on
inclines, pull switch m twice.
The electrical parking brake can
always be activated, even if the
ignition is off.
Do not operate electrical parking
brake system too often without
engine running as this will discharge
the battery.
Before leaving the vehicle, check the
electrical parking brake status.
Control indicator m 3 85.
Releasing
Switch on ignition. Keep foot brake
depressed and then push switch m.
If the foot brake is not depressed
when attempting to release electrical
parking brake, a warning chime will
sound and control indicator -
