When operating the retractable
hardtop ■ Indicator buzzer upon completed opening or closing of the
convertible hardtop.
■ Indicator buzzer upon completed raising or lowering of the electricload compartment loading aid.
■ Gong tone if the tailgate is not closed during roof operation.
■ Gong tone if the tailgate is not fully open during operation of the load
compartment loading aid.
■ Gong tone during roof operation if vehicle speed exceeds 30 km/h.
■ Gong tone when vehicle speed exceeds 30 km/h if the roof is not
fully open or closed.
■ Three gong tones during roof or loading aid operation if the load
compartment blind is not attached.
■ Three gong tones during roof operation if outside temperature is
below -20 °C, vehicle battery
voltage is too low or the system is
overloaded.■ Continuous warning buzzer during roof operation if the anti-roll bars
have been triggered.
■ Continuous warning buzzer starting
one minute before the end of the
9-minute standby time with the roof
in an intermediate position or the loading aid in a raised position.
■ Persistent warning buzzer when closing the tailgate, if the lowering
process of the electric load aid is
not complete or has been
interrupted.
Battery voltage
Low battery voltage in radio remote
control or electronic key. On vehicles
without check control, the message
InSP3 appears in the instrument
panel display. Replace the battery
3 20, 3 22.
Brake light switch
Brake light does not come on during
braking. Have the cause of the fault
remedied immediately by a
workshop.Engine cooling level
Low fluid level in engine cooling
system. Check coolant immediately
3 162.

If there is water in the diesel fuel filter, the message InSP4 appears in the
instrument panel. Consult a
workshop.

130Climate control
Air conditioning with the engine
not running When ignition is off, the residual heat
or cooling in the system can be used
for climate control in passenger
compartment.
Press the AUTO button with the
ignition off. Residual air conditioning
on will appear briefly in the display.
Residual climate control can only
operate for a limited period of time. To
cancel, press the AUTO button.
Auxiliary heater
Air heater Quickheat is an electric auxiliary air
heater which warms up the
passenger compartment more
quickly.
Coolant heater Diesel-engined vehicles have a fuel-
powered auxiliary heater.Air vents
Adjustable air vents
At least one air vent must be open
while cooling is on in order to prevent
the evaporator from icing up due to lack of air movement.
To open vent, turn the adjuster wheel
to B.
Direct the flow of air by tilting and
swivelling the slats.
To close the vent, turn the adjuster
wheel to 7.
9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.
Fixed air vents
Additional air vents are located
beneath the windscreen and door windows and in the foot wells.

Accessories and vehicle
modifications
We recommend using genuine parts and accessories and factory
approved parts specific for your
vehicle type. We cannot assess or guarantee reliability of other products
- even if they have a regulatory or
otherwise granted approval.
Do not make any modifications to the electrical system, e.g. changes of
electronic control units (chip tuning).Caution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
Vehicle storage
Storage for a long period of time
The following must be done if the
vehicle should be stored for several months:
■ Wash and wax the vehicle.
■ Have the wax in the engine compartment and underbody
checked.
■ Clean and preserve rubber seals.
■ Fill up fuel tank completely.
■ Change engine oil.
■ Drain washer fluid reservoir.
■ Check coolant antifreeze.
■ Adjust tyre pressure to the value specified for full load.
■ Park vehicle in dry, well ventilated place. Engage first or reverse gear
or set selector lever to P. Prevent
the vehicle from rolling.
■ Do not apply parking brake.
Page 162 of 245
160Vehicle care
■ Open bonnet, close all doors andlock the vehicle.
■ Disconnect the clamp from the negative terminal of the vehicle
battery. Be aware that all systems
are non-operational, e.g. the anti-
theft alarm system.
Putting back into operation The following must be done if the
vehicle is put back into operation:
■ Connect the clamp to the negative terminal of the vehicle battery.
Activate the electronics of the
power windows.
■ Check tyre pressure.
■ Fill up the washer fluid reservoir.
■ Check the engine oil level.
■ Check the coolant level.
■ Fit the number plate if necessary.End-of-life vehicle
recovery
Information about end-of-life vehicle
recovery centres and the recycling of
end-of-life vehicles is available on our website. Only entrust this work to an
authorised recycling centre.Vehicle checks
Performing work9 Warning
Only perform engine compartment
checks when the ignition is off.
The cooling fan may start
operating even if the ignition is off.
Page 163 of 245

Vehicle care1619Danger
The ignition system and Xenon
headlights use extremely high
voltage. Do not touch.
The caps for topping up the engine oil, the coolant, the washing fluid and theoil dipstick handle are yellow for ease
of identification.
Bonnet
Opening
Pull the release lever and return it to
its original position.
Lift the safety catch upwards and
open the bonnet.
Air intake 3 131.
Secure the bonnet support.
Closing Before closing the bonnet, press the
support into the holder.
Lower the bonnet and allow it to drop into the catch. Check that the bonnet
is engaged.
Engine oil
Check the engine oil level manuallyon a regular basis to prevent damage
to the engine. Ensure that the correct specification of oil is used.
Recommended fluids and lubricants
3 208.
Check with the vehicle on a level
surface. The engine must be at
operating temperature and switched
off for at least 5 minutes.
Pull out the dipstick, wipe it clean, insert it to the stop on the handle, pull
it out and read the engine oil level.
Insert the dipstick to the stop on the
handle and make half a turn.
Page 164 of 245
162Vehicle care
Different dipsticks are used
depending on engine variant.When the engine oil level has
dropped to the MIN mark, top up
engine oil.
We recommend the use of the same
grade of engine oil that was used at
last change.
The engine oil level must not exceed
the MAX mark on the dipstick.Caution
Overfilled engine oil must be
drained or suctioned out.
Capacities 3 224.
Fit the cap on straight and tighten it.
Engine coolant The coolant provides freeze
protection down to approx. -28 °C.
Caution
Only use approved antifreeze.
Page 165 of 245
Vehicle care163
Coolant levelCaution
Too low a coolant level can causeengine damage.
When the cooling system is cold, the
coolant level should be just above the
KALT/COLD mark. 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.
Top up with antifreeze. If no
antifreeze is available, use clean tap
water or distilled water. Install the cap
tightly. Have the antifreeze
concentration checked and have the
cause of the coolant loss remedied by a workshop.
Washer fluid
Fill with clean water mixed with a
suitable quantity of windscreen
washer fluid which contains
antifreeze.
Brakes A squealing noise indicates that the
brake lining is at its minimum
thickness. Continued driving is
possible but have the brake lining
replaced as soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
