To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Restart of the engine by the driver Depress the clutch pedal to restart the
engine.
The engine start is indicated by the
needle at the idle speed position in
the tachometer.
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.
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.
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.
142Driving and operatingEnsure the radiator core and the areabetween the radiator and intercooler/
oil cooler (where installed) is cleaned, to maintain proper cooling air flow.Check the radiator and cooler cores
for blockage (sand, silt etc.).
Check the tyre treads.
Clean and check the mechanical
parts of the vehicle, particularly the
following areas:
● Driveshafts, including sealing bellows
● Front brake calipers, pads and discs
● Front suspension
● Clutch fork sealing bellows
● Rear brake calipers, pads and discs
● Rear suspension
● Fuel tank and underguard
● Breathers, axles and fuel tank
● Load sensing valve
● Transfer box and underguard
● Engine oil pan and underguardObserve the following: ● Do not spray high-pressure water
directly at the vehicle seals
● The wheels must be removed to clean all mud and stones from the
brake calipers and to check
brake pad wear
● The areas on the upper side of the underguards must be clearedof stones, to prevent damage to
the engine oil pan and the fuel
tankBrakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has
been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 85.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.
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 -
illuminates in the instrument cluster
3 90.
Driving and operating153Adjust tyre pressure to the value
specified for full load 3 212.
Trailer towing Trailer loadsThe permissible trailer loads are
vehicle-dependent and engine-
dependent maximum values which
must not be exceeded. The actual
trailer load is the difference between
the actual gross weight of the trailer
and the actual coupling socket load
with the trailer coupled.
When the trailer load is being
checked, therefore, only the trailer
wheels - and not the jockey wheel -
must be standing on the weighing
apparatus.
The permissible trailer loads are
specified in the vehicle documents. In general, they are valid for gradients
up to max. 12%.
The permitted trailer load applies up
to the specified incline and up to an
altitude of 1000 metres above sea
level. Since engine power decreases
as altitude increases due to the airbecoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10%
for every 1000 metres of additional
altitude. The gross train weight does
not have to be reduced when driving
on roads with slight inclines (less than
8%, e.g. motorways).
The permissible gross train weight
must not be exceeded. This weight is specified on the identification plate3 205.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load (80 kg) is specified on
the towing equipment identification
plate and in the vehicle documents.
Always aim for the maximum load,
especially in the case of heavy
trailers. The vertical coupling load
should never fall below 25 kg.When measuring the vertical coupling
load, ensure the drawbar of the
loaded trailer is at the same height as it will be when the trailer is coupled
with the towing vehicle loaded. This is
particularly important for trailers with
tandem axle.
Rear axle load
When the trailer is coupled and the
towing vehicle is fully loaded
(including all occupants), the
permissible rear axle load (see
identification plate or vehicle
documents) must not be exceeded.
National regulations regarding
maximum speeds for vehicles towing a trailer must be observed.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
