Driving and operating125
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■ the self-cleaning function of the diesel particle filter is not active
■ the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details 3 116.
Immediately after motorway driving
an Autostop may be inhibited.

neutral before depressing the clutch
first, control indicator - illuminates.
Control indicator - 3 89.
Restart of the engine by the
stop-start system
The selector lever must be in neutral to enable an automatic restart.
If one of the following conditions occurs during an Autostop, the
engine will be restarted automatically
by the stop-start system.
■ The stop-start system is manually deactivated
■ the bonnet is opened
■ the driver's seat belt is unfastened and the driver's door is opened
■ the engine temperature is too low
■ the charging level of the vehicle battery is below a defined level
■ the brake vacuum is not sufficient
■ the vehicle is driven at least at walking speed
■ the defrosting function is activated■ the climate control system requests
an engine start
■ the air conditioning is manually switched on
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during restart might be noticeable.
Parking ■ Do not park the vehicle on an easily
ignitable surface. The high
temperature of the exhaust system
could ignite the surface.
■ Always apply the electrical parking brake.
Pull switch m.
For maximum force, e.g. parking
with a trailer or on inclines, pull
switch m twice.
■ Switch off the engine and turn the ignition key to position LOCK, push
key into ignition switch and remove.
Turn the steering wheel until the
steering wheel lock is felt to
engage.For vehicles with automatic
transmission, depress foot brake
and shift into P before pushing key
into ignition switch and removing.
■ If the vehicle is on a level surface or
uphill slope, engage first gear ormove the selector lever to P before
switching off the ignition. On an
uphill slope, turn the front wheels
away from the kerb.
If the vehicle is on a downhill slope, engage reverse gear or move the
selector lever to P before switching
off the ignition. Turn the front
wheels towards the kerb.
■ Lock the vehicle with button p on
the radio remote control 3 20 and
activate the anti-theft alarm system 3 24.
Driving and operating131
Activation
In automatic mode, press button
s ; control indicator s
illuminates in the instrument cluster 3 88.
The settings of certain electronic
systems are adapted to reduce fuel
consumption:
■ The engine reacts less quickly to the accelerator pedal.
■ Automatic upshift points occur sooner and downshift points occur
later.
■ The transmission locks itself to the engine at cruising speeds, to
improve efficiency and increase
power and torque.
■ The fuel supply is automatically cut-
off more quickly during vehicle
deceleration. Overrun cut-off
3 124.
Do not use fuel economy mode whilst towing, e.g. a trailer.Deactivation
Fuel economy mode is switched off
by pressing button s again;
control indicator s extinguishes in
the instrument cluster.
Fault
In the event of a fault in the automatic
transmission, control indicator Z
illuminates in the instrument cluster 3 84 . Automatic shifting may be much
harsher than normal or, in the case of
a serious fault, cancelled altogether.
Have the cause of the fault remedied
by a workshop.
If control indicator g illuminates in
the instrument cluster when the
engine is running, this may indicate a
fault in the transmission electronics
3 84. The electronics switch to the
emergency running programme, fuel
consumption may increase and the
driveability of the vehicle may be
affected. Seek the assistance of a
workshop.Interruption of power
supply
The 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 3 187.
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.
132Driving and operating
3. Remove trim cover.
4. Press and hold shift lock releasebutton.
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.
Caution
It is not advisable to drive with the hand resting on the selector lever.
134Driving and operating
Towing the vehicle 3 188.
Driving through water
Do not exceed the maximum wading
depth 3 204.
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 3 mph, 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. 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 serviceoperations 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 overmechanical components and cause
localised overheating and failure of
parts, especially in the engine
compartment.
Ensure the radiator core and the area between 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
Driving and operating141
Deactivation
Press the e button; control
indicator m extinguishes and the
vehicle slowly decelerates.
Automatic deactivation: ■ vehicle speed below approx. 25 mph,
■ the brake pedal is depressed,
■ the clutch pedal is depressed,
■ selector lever in N,
■ the Electronic Stability Control is operating.
Resume stored speed
Press the + RES button at a speed
above 25 mph. The stored speed will
be obtained.
Deleting the stored speed The stored speed will be deleted by
pressing the e button or
switching off the ignition.Parking assist
The parking assist system makes
parking easier by measuring the
distance between the vehicle and obstacles to the front and rear, and
giving acoustic signals. It is the driver,
however, who bears full responsibility for the parking manoeuvre.
The system consists of four ultrasonic
parking sensors in both the front and
rear bumpers.
Control indicator r 3 86.
Activation
With the ignition on, the system must
be activated manually.
Press button r on the instrument
panel. The LED in the button will
illuminate and will activate when a
forward gear or reverse gear is
engaged and the electrical parking
brake is released.
An obstacle is indicated by an
acoustic signal. The interval between
the sounds becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
156Vehicle careCaution
Only use high-performance brake
fluid approved for the vehicle.
Brake fluid 3 195.
Brake fluid level control indicator R
3 84.
Clutch fluid
9 Warning
Clutch fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
If the fluid in the reservoir falls below
the MIN mark, seek the assistance of
a workshop.
Clutch fluid 3 195.
Vehicle battery Vehicles without stop-start system
will be equipped with a lead acid
battery. Vehicles with stop-start
system will be equipped with an
AGM vehicle battery which is not a
lead acid battery.
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the vehicle battery. Avoid the use of
unnecessary electrical consumers.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
6 weeks can lead to battery
discharge. Disconnect the clamp from the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.
The anti-theft alarm siren must be
deactivated as follows: Switch the ignition on then off, disconnect the
vehicle's battery within 15 seconds.
196Service and maintenance
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 199.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade
depending on the minimum ambient
temperature 3 199.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.Coolant and antifreeze
Use only silicate-free long life coolant
(LLC) antifreeze. Consult a
workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant
provides frost protection down to
approx. -37°C. This concentration
should be maintained all year round.
The use of additional coolant
additives that intend to give additional corrosion protection or seal against
minor leaks can cause function
problems. Liability for consequences
resulting from the use of additional
coolant additives will be rejected.
Brake and clutch fluid Only use high-performance DOT4+
brake fluid approved for the vehicle.
Consult a workshop.Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified
interval.
Brake fluid should be stored in a
sealed container to avoid water
absorption.
Ensure brake fluid does not become contaminated.
