Functional requirements of the auxiliary heating (aux. heating and ventilation) The charge state of the vehicle battery is sufficient.
The fuel supply is adequate (the warning light is not illuminated in the
instrument cluster).
Aux. heating
The auxiliary heating can be used when both when stationary, when the en-
gine is switched off, to preheat the vehicle and also while driving (e.g. during
the heating phase of the engine).
The auxiliary heating warms up the coolant by combusting fuel from the vehi-
cle tank. This heats the air flowing into the passenger compartment (if the
blower is turned on).
The auxiliary heating also warms up the engine.
The heater is switched on or off automatically depending on the ambient con-
ditions to give the best possible conditions for the engine running and the in-
terior heating.
For vehicles with gasoline engines, the automatic switching on and off of the
heater can be disabled in a specialist workshop.
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun).
109Heating and ventilation

WARNING■The auxiliary heating (auxiliary heating and ventilation) (hereinafter refer-
red to as aux. heating) must never be operated in closed rooms (e.g. garag-
es) – risk of poisoning!■
The auxiliary heating must not be allowed to run during refuelling – risk
of fire.
■
The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. If you want to use the heater, do not switch off the car in pla-
ces where the exhaust fumes can come into contact with flammable mate-
rials such as dry grass, undergrowth, leaves, spilled fuel etc. -. risk of fire.
CAUTION
■ The exhaust pipe of the auxiliary heating, which is located on the underside
of the vehicle, must not be clogged and the exhaust flow must not be blocked.■
If the auxiliary heating is running, the vehicle battery discharges. If the auxili-
ary heating and ventilation has been operated several times over a longer peri-
od, the vehicle must be driven a few kilometres in order to recharge the vehi-
cle battery.
■
The air inlet in front of the windscreen must be free (e.g. of ice, snow or
leaves) to ensure that the auxiliary heating operates properly.
Note
■ The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.■
At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operat-
ing problem.
■
So that warm air can flow into the vehicle interior after switching on the aux.
heating, you must maintain the comfort temperature normally selected by you,
leave the fan switched on and leave the air outlet vents in open. It is recom-
mended to put the air flow in the position
or
.

OperationFig. 132
Prompt in the MAXI DOT display
Vehicles with manual transmission
The engine is automatically switched off as soon as the vehicle comes to a
halt, the shift lever is moved into neutral and the clutch pedal is released.
The engine is automatically started as soon as the clutch pedal is depressed.
Vehicles with automatic transmission
The engine is automatically switched off as soon as the vehicle comes to a halt
and the brake pedal is operated.
The engine is automatically started as soon as the brake pedal is released.
Requirements for the system to function correctly
The following conditions must be met for the system to function correctly.
The driver's door is closed.
The driver has fastened the seat belt.
The bonnet is closed.
The driving speed was higher than 4 km.h after the last stop.
No trailer is coupled.
System status
The system status is indicated in the instrument cluster display when stopped.
The engine is automatically switched off; when the vehicle moves off the igni-
tion process will be automatically initiated.
» Fig. 132
START-STOP ACTIVE
The engine is not automatically switched off.
» Fig. 132
START-STOP NOT POSSIBLEReasons for the engine running
It may be essential for the engine to keep running when the vehicle comes to
a halt, for the following reasons. ▶ The engine temperature for the proper function of the system has not yet
been reached.
▶ The charge state of the vehicle battery is too low.
▶ The current consumption is too high.
▶ High air-conditioning or heating capacity (high fan speed, big difference be-
tween the desired and actual interior temperature).
When the engine is shut-down automatically and the system detects that the engine is required such as when the brake pedal is pressed repeatedly then
the system automatically starts the engine.
Note
■ If the vehicle remains outdoors for a long time in minus temperatures or in
direct sunlight, it can take several hours until the internal temperature of the
vehicle battery reaches a suitable temperature for proper operation of the
START STOP system.■
If the driver's seat belt is removed for more than approx. 30 seconds or the
driver's door is opened during stop mode, the engine will have to be started
manually.
■
No automatic engine shut-down takes place when a vehicle with automatic
transmission is moving at low speed (e.g. during a traffic jam) and remains sta-
tionary after pressing the brake pedal lightly. Automatic engine shutdown
takes place if you press the brake pedal down with more force.
■
For vehicles with automatic transmission there is no automatic engine shut-
down when the system detects a manoeuvring action due to a large steering
angle.

Long or steep slopes
Before travelling a long distance with a steep gradient, reduce speed and shift
into the next lowest gear. As a result, the braking effect of the engine will be
used, reducing the load on the brakes. Any additional braking should be com-
pleted intermittently, not continuously.
Emergency brake display
If the brakes are applied in full and the vehicle systems evaluate the situation
as dangerous for the traffic following behind, the brake light flashes automati-
cally.
After the speed was reduced below around 10 km/h or the vehicle was stop-
ped, the brake light stops flashing and the hazard warning light system
switches on. The hazard warning light system is switched off automatically af-
ter accelerating or driving off again.
Faults in the brake surface
If it is found that the braking distance has suddenly become longer and that
the brake pedal can be depressed further, the brake system may be faulty.
Visit a specialist garage immediately and adjust your style of driving appropri-
ately, as you will not know the exact extent of the damage.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system.
The level of the brake fluid is monitored electronically » page 33,
Brake sys-
tem .
Brake booster
The brake booster increases the pressure generated with the brake pedal. The
brake booster only operates when the engine is running.WARNINGOnly apply the brakes for the purpose of drying and cleaning the brake
discs if the traffic conditions permit this. Do not place any other road users
in jeopardy.HandbrakeFig. 134
Handbrake
Read and observe and on page 119 first.
The hand brake is used when stopping and parking for securing the vehicle
against unwanted movement.
Apply
›
Pull the handbrake lever firmly upwards.
Release
›
Pull the handbrake lever up slightly and at the same time push in the lock
button » Fig. 134 .
›
Move the lever right down while pressing the lock button.
The handbrake indicator light lights up when the handbrake is applied, pro-
vided the ignition is on.
A warning signal sounds if the vehicle is inadvertently driven off with the
handbrake applied.
The following message is shown in the MAXI DOT display.
Release parking brake!
The handbrake warning is activated if the vehicle is driven at a speed of more
than around 5 km/h for more than 3 seconds.
WARNINGPlease note that the handbrake must be fully released. A handbrake which
is only partially released can result in the rear brakes overheating. This can
have a negative effect on the operation of the brake system – risk of acci-
dent!120Driving

New tyres
New tyres must firstly be “run in”, as they do not offer optimal grip at first.
Therefore, drive especially carefully for the first 500 km or so.
New brake pads
New brake pads have to first “grind in” because these do not initially have the
best possible braking effect.
Therefore, drive especially carefully for the first 200 km or so.
Tips for economical driving
To achieve the lowest possible fuel consumption, the following instructions
must be observed.
Looking ahead when driving
Avoid unnecessary acceleration and braking.
Switch in an energy saving and timely manner Observe the recommended gear » page 40.
Avoid full throttle and high speeds
Fuel consumption can be reduced by half if only three-quarters of the possible
top speed of your vehicle is used.
Reducing idling
If the vehicle is fitted with the START - STOP system there is an automatic re-
duction of the idling. If the engine is stopped on vehicles without START-STOP
system, such as when waiting in a traffic jam, the fuel economy is already
greater after 30 - 40 s than the fuel quantity which is required for engine re-
start.
Avoid short distances
When driving a short distance of less than about 4 km, the engine cannot
reach its operating temperature. As long as the engine has not reached oper-
ating temperature, the fuel consumption is significantly higher than with the
engine hot.
Pay attention to the correct tyre inflation pressure being maintained
Further information » page 176.
Avoid unnecessary ballast
Per 100 kg of weight, consumption increases by about 0.3 l/100 km. At a speed
of 100 - 120 km/h, a vehicle fitted with a roof rack cross member without a load
will use about 10 % more fuel than normal due to the increased aerodynamic
drag.
Saving electricity
Only turn on electrical consumers (e.g. seat, window and mirror heating, etc.)
for as long as necessary.
Use the cooling system economically
The air conditioning system compressor uses power from the engine when in
cooling mode, which will affect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the
interior has been strongly heated through the effect of direct sunlight in order
to allow the heated air to escape.
The cooling system should not be on if the windows are open.

125Starting-off and Driving

Plastic partsRead and observe
and on page 154 first.
Clean plastic parts with a damp cloth.
If this method does not completely clean the plastic parts, use cleaning prod-
ucts specially designed for this purpose.
CAUTION
Do not use paint care products on plastic parts.
Rubber seals
Read and observe
and on page 154 first.
All door seals and window guides are factory-treated with a colourless mattvarnish layer to prevent the freezing of painted body parts and to protect
against driving noise.
CAUTION
■ Do not treat the door seals and window guides with any products.■Applying additional treatments to the seals can corrode the protective coat-
ing, and driving noise may occur.
Chrome and anodized parts
Read and observe
and on page 154 first.
First clean the chrome parts and anodized parts with a damp cloth and thenpolish them with a soft, dry cloth.
If this method does not completely clean the parts, use cleaning products spe-
cially designed for this purpose.
CAUTION
■ Do not polish the chrome parts and anodized parts in a dusty environment -
risk of surface scratches.■
Never use aggressive cleaning agents or chemical solvents for these parts -
there is risk of damage.
Windows and mirrors
Read and observe
and on page 154 first.
Removing snow and ice
Use a plastic ice scraper for removing snow and ice from the windows and mir-
rors.
Cleaning windows
Regularly clean windows from the inside with clean water.
Dry the glass surfaces with a clean chamois leather or a cloth intended for this
purpose.
CAUTION
Instructions for removing snow and ice■The ice scraper should not be moved forward and backward but in one direc-
tion to avoid any damage to the surface of the glass.■
Snow or ice that is contaminated with coarse dirt such as fine gravel, sand or
salt must not be removed from the windows and mirrors – there is a risk of
damage to the surface of the windows and mirrors.
■
Do not remove snow or ice from glass parts using warm or hot water – risk of
cracks forming in the glass.
■
Make sure that when removing snow and ice from the windows, the labels
attached to the vehicle by the factory are not damaged.
CAUTION
Information for cleaning windows■Do not clean the inside of the windows with sharp-edged objects or corro-
sive and acidic cleaning agents – there is a risk of damaging the heating ele-
ments or window aerial.■
When drying the windows after washing the vehicle, do not use window
leathers that have been used to polish the bodywork. Residues of preserva-
tives in the window leather can make the window dirty and reduce visibility.
Headlight glasses
Read and observe
and on page 154 first.
Clean plastic front headlight lenses using clean, warm water and soap.
155Care and maintenance

CAUTION■For Alcantara ®
seat covers, do not use any solvents, floor wax, shoe cream,
stain remover, leather cleaners or similar agents.■
Avoid leaving the vehicle in bright sunlight for long periods of time in order
to stop the artificial leather, materials or Alcantara ®
from bleaching. During ex-
tended periods of standing outdoors, protect artificial leather, fabrics or Alcan-
tara ®
by covering.
■
Some clothing materials, e.g. dark denim, do not have sufficient colour fast-
ness. This can cause damage or clearly visible discolouration to seat covers,
even when used correctly. This applies particularly to light-coloured seat cov-
ers. This does not relate to a fault in the seat cover, but rather to poor colour
fastness of the clothing textiles.
Seat covers
Read and observe
and on page 157 first.
Electrically heated seats
Use a specific cleaning agent such as dry foam or similar to clean the covers. »
.
Seats without seat heating
Thoroughly vacuum the seat covers with a vacuum cleaner before cleaning.
Clean the seat covers with a damp cloth or cleaning products specially de-
signed for this purpose.
Indented points arising on the fabrics by everyday use, can be removed by
brushing against the direction of hair with a damp brush.
Always clean all parts of the covers, so that there are no visible edges. Then
allow the seat to dry completely.
CAUTION
■ Do not clean the covers of electrically heated seats either with water or with
other liquids - there is a risk of damaging the seat heating system.■
Regularly remove dust from the seat covers using a vacuum cleaner.
■
Electrically heated seats must not be dried after cleaning by switching on the
heater.
■
Do not sit on wet seats - risk of seat deformation.
■
Always clean the seats from “seam to seam”.
Safety belts
Read and observe
and on page 157 first.
Wash dirty seat belts with mild soapy water.
Remove coarse dirt with a soft brush.
WARNING■ The seat belts must not be removed for cleaning.■Never clean the seat belts chemically as chemical cleaning products could
destroy the fabric.■
The seat belts must not be allowed to come into contact with corrosive
liquids (e.g. acids).
