General hints for operating
tailgate9 Danger
Do not drive with the tailgate open
or ajar, e.g. when transporting
bulky objects, since toxic exhaust
gases, which cannot be seen or
smelled, could enter the vehicle.
This can cause unconsciousness
and even death.
Caution
Before opening the tailgate, check overhead obstructions, e.g. a
garage door, to avoid damage to
the tailgate. Always check the
moving area above and behind the
tailgate.
Note
The installation of certain heavy
accessories onto the tailgate may
affect its ability to remain open.
Vehicle security
Anti-theft locking system9 Warning
Do not use the system if there are
people in the vehicle! The doorscannot be unlocked from the
inside.
The system deadlocks all the doors.
All doors must be closed otherwise
the system cannot be activated.
If the ignition was on, the driver's door
must be opened and closed once so
that the vehicle can be secured.
Unlocking the vehicle disables the
mechanical anti-theft locking system.
This is not possible with the central
locking button.
Activating
Press e on the radio remote control
twice within 15 seconds.
Anti-theft alarm system The anti-theft alarm system is
combined with the anti-theft locking
system.
It monitors: ■ Doors, tailgate, bonnet
■ Passenger compartment including adjoining load compartment
■ Vehicle inclination, e.g. if it is raised
■ Ignition
28Keys, doors and windows
Activation■ Self-activated 30 seconds after locking the vehicle (initialisation of
the system)
■ Directly by pressing e on the radio
remote control once more after locking
Note
Changes to the vehicle interior such
as the use of seat covers, and open
windows or sunroof, could impair the
function of passenger compartment
monitoring.
Activation without monitoring of
passenger compartment and vehicle inclination
Switch off the monitoring of
passenger compartment and vehicle
inclination when animals are being
left in the vehicle, because of high
volume ultrasonic signals or
movements triggering the alarm. Also switch off when the vehicle is on a
ferry or train.
1. Close tailgate, bonnet and windows.
2. Press button o. LED in the
button o illuminates for a
maximum of 10 minutes.
3. Close doors.
4. Activate the anti-theft alarm system.

■ the engine is warmed-up
■ the engine coolant temperature is not too high
■ the engine exhaust temperature is not too high, e.g. after driving with
high engine load
■ the ambient temperature is above -5° C
■ the climate control system allows an Autostop

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 3 152.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 160.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several battery discharge protection
features are implemented as part of
the stop-start system.
Power saving measures
During an Autostop, several electrical
features such as auxiliary electric
heater or rear window heating are
disabled or switched into a power-
saving mode. The fan speed of the
climate control system is reduced to
save power.
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.
If the selector lever is shifted out of
neutral before depressing the clutch
first, control indicator - illuminates
or is shown as a symbol in the Driver Information Centre.
Control indicator - 3 112.
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 charge level of the vehicle battery is below a defined level
224Vehicle care
■ Open the bonnet, close all doorsand lock the vehicle.
■ Disconnect the clamp from the negative terminal of the vehicle
battery. Beware that all systems are not functional, e.g. anti-theft alarm
system.
Putting back into operation When the vehicle is to be 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 on end-of-life vehicle
recovery centres and the recycling of
end-of-life vehicles is available on ourwebsite, where legally required. Only
entrust this work to an authorised
recycling centre.
Gas vehicles must be recycled by a
service centre authorised for gas
vehicles.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.
Vehicle care2259Danger
The ignition system and Xenon
headlights use extremely high
voltage. Do not touch.
Bonnet
Opening
Pull the release lever and return it to
its original position.
Move the safety catch sideways to the left vehicle side and open the bonnet.
The bonnet is held open
automatically by a lifter.
If the bonnet is opened during an
Autostop, the engine will be restarted automatically for safety reasons.
Closing
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
3 269.
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
out and read the engine oil level.
Insert dipstick to the stop on the
handle and make half a turn.
Vehicle care265
If using a vehicle wash, comply with
the vehicle wash manufacturer's
instructions. The windscreen wiper and rear window wiper must be
switched off. Remove antenna and
external accessories such as roof
racks etc.
If you wash your vehicle by hand,
make sure that the insides of the
wheel housings are also thoroughly
rinsed out.
Clean edges and folds on opened
doors and the bonnet as well as the
areas they cover.Caution
Always use a cleaning agent with
a pH value of 4 to 9.
Do not use cleaning agents on hot surfaces.
Have the door hinges of all doors
greased by a workshop.
Do not clean the engine compartment with a steam-jet or high-pressure jet
cleaner.
Thoroughly rinse and leather-off the vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Do not use hard objects to remove
spots of tar. Use tar removal spray on
painted surfaces.
Exterior lights
Headlight and other light covers are
made of plastic. Do not use any
abrasive or caustic agents, do not use an ice scraper, and do not clean them
dry.
Polishing and waxing Wax the vehicle regularly (at the
latest when water no longer beads).
Otherwise, the paintwork will dry out.
Polishing is necessary only if the paint
has become dull or if solid deposits
have become attached to it.
Paintwork polish with silicone forms a
protective film, making waxing
unnecessary.
Plastic body parts must not be treated with wax or polishing agents.Windows and windscreen wiper
blades
Use a soft lint-free cloth or chamois
leather together with window cleaner and insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Clean smearing wiper blades with a
soft cloth and window cleaner.
Glass panel Never clean with solvents or abrasive
agents, fuels, aggressive media
(e.g. paint cleaner, acetone-
containing solutions etc.), acidic or
highly alkaline media or abrasive
pads.
Wheels and tyres Do not use high-pressure jet
cleaners.
