Instruments and controls105Warning chimesIf several warnings appear at the
same time, only one warning chime will sound.
When starting the engine or whilst driving
The warning chime regarding
unfastened seat belts has priority
over any other warning chime.
● If a door, the tailgate or bonnet is
open.
● If seat belt is not fastened. ● If a certain speed is exceeded with parking brake applied.
● If a programmed speed or speed
limit is exceeded.
● If a warning message appears in the Driver Information Centre.
● If approaching a vehicle ahead too closely.
● If the electronic key is not in the passenger compartment.
● If an unintended lane change occurs.● If the parking assist detects anobject.
● 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 warning code 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.
134Driving and operatingDriving hints
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 3 139.
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 3 142.
Driving and operating141Restart 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 climate control system requests an engine start.
● The air conditioning is manually switched on.If the bonnet is not fully closed, a
warning message is displayed in the
Driver Information Centre.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during engine 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 parking brake. Activate the parking
brake without pressing the
release button. Apply as firmly
as possible on a downhill slope
or uphill slope. Depress brake
pedal at the same time to
reduce operating force.
● Switch off the engine.
● If the vehicle is on a level surface or uphill slope, engage
first gear or set the selector
lever to position 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
set the selector lever to position P before removing the ignition
key. Turn the front wheels
towards the kerb.
● Close the windows and the sunroof.
● Remove the ignition key from the ignition switch. For vehicles
with automatic transmission,
the key can only be removed
when the selector lever is in
position P.
Turn the steering wheel until
the steering wheel lock is felt to engage.
● Lock the vehicle.
● Activate the anti-theft alarm system.
186Vehicle care
The brake fluid level must be betweenthe MIN and the MAX marks.
If fluid level is below MIN seek the
assistance of a workshop.
Brake and clutch fluid 3 222.
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 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
four 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.
Vehicle battery discharge protection
3 126.
Replacing the vehicle battery Note
Any deviation from the instructions
given in this section may lead to
temporary deactivation or
disturbance of the stop-start system.
When the vehicle battery is being
replaced, please ensure that there
are no open ventilation holes in the
vicinity of the positive terminal. If a
ventilation hole is open in this area, it
must be closed off with a dummy cap,
and the ventilation in the vicinity of the negative terminal must be opened.
Only use vehicle batteries that allow the fuse box to be mounted above the
vehicle battery.
Ensure that the battery is always replaced by the same type of battery.
We recommend that you have the
vehicle battery replaced by a
workshop.
Stop-start system 3 139.
Charging the vehicle battery9 Warning
On vehicles with stop-start
system, ensure that the charging
potential does not exceed 14.6 V
