● If the electronic key is not in the passenger compartment.
● If an unintended lane change occurs.● If the parking assist detects an object.
● If the fuel level is low.
When the vehicle is parked and/or the driver's door is opened
● With exterior lights on.
During an Autostop ● If the driver's door is opened.
● If any condition for an autostart is
not fulfilled.
Battery voltage
When the battery voltage is running low, a warning message or warningcode 174 will appear in the Driver
Information Centre.
1. Switch off immediately any electrical consumers which are
not required for a safe ride, e.g.
seat heating, heated rear window
or other main consumers.
2. Charge the battery by driving continuously for a while or by
using a charging device.The warning message or warning
code will disappear after the engine
has been started twice consecutively without a voltage drop.
If the battery cannot be recharged,
have the cause of the fault remedied
by a workshop.
122Climate controlAir conditioning system
In addition to the heating and
ventilation system, the air
conditioning system has controls for:
n:cooling4:air recirculation
Cooling n
Press n to switch on cooling. The
LED in the button illuminates to
indicate activation. Cooling is only
functional when the engine is running and climate control fan is switched on.
Press n again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is above a
specific level. Therefore
condensation may form and drip from under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons. Activated cooling
may inhibit Autostops.
Stop-start system 3 133.
Air recirculation system 4
Press 4 to activate air recirculation
mode. The LED in the button illuminates to indicate activation.
Press 4 again to deactivate air
recirculation mode.9 Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen may mist
up from outside when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate l.
Maximum cooling
Briefly open the windows so that hot
air can disperse quickly.
● Switch on cooling n.
● Air recirculation system 4 on.
● Press air distribution switch M.
● Set temperature control to coldest level.
● Set fan speed to highest level.
● Open all vents.

● Open side air vents as required and direct them towards the doorwindows.
Notice
If V is pressed while the engine is
running, an Autostop will be inhibited
until V is pressed again.
If l is pressed with the fan switched
on and the engine running, an
Autostop will be inhibited until l is
pressed again or until the fan is
switched off.
If V is pressed while the engine is
in an Autostop, the engine will restart automatically.If l is pressed with the fan switched

the climate control system runs at maximum heating.
Notice
If the temperature is to be reduced
for climate comfort reasons, an
Autostop may be inhibited or the
engine will restart automatically
when cooling is switched on.

Air recirculation mode 4
Press 4 once to activate the
manual air recirculation mode.9 Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
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.
Auxiliary heater Air heater Quickheat is an electric auxiliary air
heater which automatically warms up
the passenger compartment more
quickly.
Air vents
Adjustable air vents At least one air vent must be open
while the cooling is on.
To open the vent, turn the adjuster
wheel to the right. Adjust the air
amount at the vent outlet by turning
the adjuster wheel.

Control of the vehicle
Never 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 3 133.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
Use only floor mats, which fit properly
and are fixed by the retainers on the
driver side.Steering
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.
A vehicle message will be displayed
in the Info Display.Caution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 10 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.
Starting and operating
New vehicle running-in
Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period fuel and engine oil consumption may be
higher and the cleaning process of the exhaust filter may take place more
often. Autostop may be inhibited to
allow for charging the battery.
Exhaust filter 3 136.
Driving and operating129Ignition switch positions0:ignition off: Some functions
remain active until key is
removed or driver's door is
opened, provided the ignition was
on previously1:accessory power mode: Steering wheel lock released, some
electrical functions are operable,
ignition is off2:ignition on power mode: Ignition
is on, diesel engine is preheating.
Control indicators illuminate and
most electrical functions are
operable. To turn the key from
position 2 to 1 or 0, first push the
key all the way in towards the steering column3:engine start: Release key after
starting procedure begins
To turn off the vehicle:
1. Make sure the vehicle is stopped.
2. If the vehicle is equipped with an automatic transmission, set the
selector lever to position P.
3. Push the key all the way in
towards the steering column, then
turn the key to position 0.
4. Remove the key.
5. Apply the parking brake.
Steering wheel lock The steering wheel is automatically
locked when the key is removed.9 Danger
Never remove the key from
ignition switch during driving as
this will cause steering wheel lock.
