Driving and operating127The engine will be switched off whilethe 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● 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.

Vehicle battery discharge protection
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.
128Driving and operatingIf the selector lever is shifted out of
neutral before depressing the clutch
first, control indicator - illuminates.
Control indicator - 3 90.
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 systemrequests 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.
Parking9 Warning
● 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.
The electric parking brake is
applied when control indicator
m illuminates 3 85.
For maximum force, e.g.
parking with a trailer or on
inclines, pull switch m twice.
● Switch off the engine.
● If the vehicle is on a level surface or uphill slope, engage
first gear or move the selector
lever to P before removing the
ignition key. 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 removing the ignition
key. Turn the front wheels
towards the kerb.
● Close windows and sunroof.
● Turn the ignition key to position
LOCK , push key into ignition
switch and remove.
For vehicles with automatic
transmission, depress foot
brake and shift into P before
pushing key into ignition switch and removing.
Turn the steering wheel until
the steering wheel lock is felt to
engage.
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.
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.
148Driving and operatingActivation
Accelerate to the desired speed,
press - SET and release it. The
current speed is stored and
maintained. Control indicator m
illuminates green. Accelerator pedal
can be released.
Vehicle speed can be increased by
depressing the accelerator pedal.
When the accelerator pedal is
released, the previously stored speed
is resumed.
Increase speed
With cruise control active, press and
hold + RES or tap + RES repeatedly:
speed increases continuously or in
small increments.
Alternatively accelerate to the desired speed and store by pressing - SET.
Reduce speed
With cruise control active, press and
hold - SET or tap - SET repeatedly:
speed decreases continuously or in
small increments.Switching off
Press e ; control indicator m
extinguishes and the vehicle slowly
decelerates.
Automatic deactivation: ● vehicle speed below approx. 45 km/h,
● the brake pedal is depressed,
● the clutch pedal is depressed,
● selector lever in N,
● the Electronic Stability Control is operating.
Resume stored speed
Press + RES at a speed above
45 km/h. The stored speed will be
obtained.
Deleting the stored speed The stored speed will be deleted by
pressing e or switching off
the ignition.Parking assist9 Warning
It is the driver who bears full
responsibility for the parking
manoeuvre.
Always check the surrounding
area while reversing and using the rear parking assist system.
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.

162Vehicle careBrake fluid9Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
The brake fluid level must be between
the MIN and MAX marks.
When topping up, ensure maximum cleanliness as contamination of the
brake fluid can lead to brake system
malfunctions. Have the cause of the
loss of brake fluid remedied by a
workshop.
Caution
Only use high-performance brake
fluid approved for the vehicle.
Brake fluid 3 202.
Brake fluid level control indicator R
3 85.
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 3 202.
Vehicle 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.
Service and maintenance203Engine 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 3 206.
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 concentrationshould 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 fluidOver time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified interval.
AdBlue
Only use AdBlue to reduce the
nitrogen oxides in the exhaust
emission 3 131.
