Control of the vehicleNever coast with engine not
running (except during Autostop)
Many systems will not function in this
situation ( e.g. brake servo unit, power
steering). Driving in this manner is a
danger to yourself and others. All
systems function during an Autostop,
but there will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 125.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.SteeringCaution
Never leave the steering wheel on
full lock when the vehicle is
stationary, as this may damage
the power steering pump.
If power steering assist is lost
because the engine stops or due to a system malfunction, the vehicle can
be steered but may require increased
effort.
Control indicator 2 3 87.
126Driving and operating
Deactivation
Deactivate the stop-start system
manually by pressing the eco button.
The deactivation is indicated when
the LED in the button extinguishes.
Autostop
If the vehicle is at a low speed or at a
standstill, activate an Autostop as
follows:
■ Depress the clutch pedal
■ set the lever to neutral
■ release the clutch pedal
The engine will be switched off while
the ignition stays on.
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
During an Autostop, the heating,
power steering and brake
performance will be maintained.
Air conditioning system may or may
not inhibit the stop-start system
according to the cooling performance.
Caution
The steering assist can be
reduced during an Autostop.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled.
■ The stop-start system is not manually deactivated
■ the bonnet is fully closed
■ the driver's door is closed or the driver's seat belt is fastened
■ the vehicle battery is sufficiently charged and in good condition
■ the engine is warmed up
■ the engine coolant temperature is not too high or low
■ the engine exhaust temperature is not too high, e.g. after driving with
high engine load
■ the ambient temperature is not too low
■ the defrosting function is not activated
■ the climate control system does not
inhibit an engine stop
■ the brake vacuum is sufficient
140Driving and operating
Switch off ESC function, to allow
engine rpm to increase, by pressing
button t briefly. Control indicator t
illuminates in the instrument cluster.
ESC is reactivated by pressing button
t again. The control indicator
extinguishes.
Control indicator t 3 88.
Hydraulic brake assist
When the ESC function comes into
action and recognises any
emergency situation requiring hard
braking, it automatically delivers
increased braking pressure to the
wheels.
Active rollover protection If the vehicle moves in an unstable
manner, this function helps the
vehicle maintain normal stability.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively braked until the snaking
ceases. While system is working keep steering wheel as still as possible.Descent control system
The Descent control system (DCS)
allows the vehicle to travel at a low
speed without depressing the foot
brake. The vehicle will automatically
decelerate to a low speed and remain
at that speed when the system is
activated. Some noise or vibration
from the brake system may be
apparent when the system is active.Caution
Use only when descending steep
grades while driving off-road. Do
not use when driving on normal
road surfaces. Unnecessary
usage of the DCS function, such
as while driving on normal roads,
may damage the brake system
and the ESC function.
Activation
At speeds below approx. 30 mph,
press button u. The green control
indicator u flashes in the instrument
cluster, to show DCS is in operation.
DCS will not activate at speeds above 30 mph, even if the button is pressed.
Deactivation
Press button u again. The green
control indicator u extinguishes.
Depressing the foot brake or
accelerator will also cause the system to be deactivated.
148Driving and operating
If no eye is available, loop cable
around coupling ball bar. Ensure
cable is crossed under the vertical
coupling socket to ensure the trailer
nose cannot drop to the ground if it
becomes separated from the trailer
hitch. Do not allow the cable to drag
along the ground and always allow
enough slack to permit full turning.
Follow the instructions supplied with
the towing equipment.
Before attaching a trailer, lubricate
the coupling ball. However, do not do
so if a stabiliser, which acts on the coupling ball, is being used to reduce snaking movements. For trailers with
low driving stability, the use of a
friction-type stabiliser is strongly
recommended.
Do not drive faster than 50 mph, even
in countries where higher speeds are
permitted. When driving uphill, do not drive faster than 20 mph in 1st gear,
or 30 mph in 2nd gear.
If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 210.
Trailer towing Trailer loads
The 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 air
becoming 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 plate
3 201.
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,
Driving and operating151
Unlock coupling ball bar and remove
key. Push lever to the left, towards the
coupling ball bar and turn it
downwards. Pull coupling ball bar out of coupling housing.
Remove any rust or dirt from area
around the coupling housing and
coupling ball bar connection before
inserting sealing plug in the hole.
Place the coupling ball bar in the bag supplied, fasten it with the strap and
stow it below the floor cover in the
load compartment.
Do not use steam-jet cleaners or
other high-pressure cleaners to clean
the coupling ball bar.
Trailer stability assist If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively braked until the snaking ceases. While system is working keep steering wheel as still as possible.
Trailer stability assist (TSA) is a
function of the Electronic Stability
Control 3 139.
156Vehicle care
If the cooling system is cold, the
coolant level should be between the
MIN and MAX marks. Top up if the
level is low.
9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Engine coolant temperature control
indicator W 3 88.
Power steering fluidCaution
Extremely small amounts of
contamination can cause steering
system damage and cause it to not work properly. Do not allow
contaminates to contact the fluid
side of the reservoir cap/dipstick or
from entering the reservoir.
Open the cap and remove. Wipe the
dipstick dry and turn the cap in the
container. Open the cap again and
read the power steering fluid level.
The power steering fluid level must be between the MIN/COLD and the
MAX /HOT marks.
If the fluid level is too low, seek the
assistance of a workshop.
