Conditions for the system function
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 driving speed was higher than 4 km.h after the last stop.
System status
The system status is shown in the display when the vehicle comes to a halt
» Fig. 231 .
The engine is automatically switched off; when the vehicle moves off, the
ignition process will be automatically initiated.
The engine is not automatically switched off.
The engine does not shut down when the vehicle stops, if e.g. the following
applies.
▶ 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 output (high fan speed, big difference be-
tween the desired and actual interior temperature).
If the engine has shut down automatically but the system detects that the en- gine is required to run (e.g. if the brake pedal is pressed repeatedly) then the
system automatically starts up the engine.
More information about the current system status can be displayed in infotain-
ment screen, in the

the instrument cluster. Seek help from a specialist garage.
Note
■ If the driver's seat belt is removed for more than 30 seconds or the driver's
door is opened after the engine has switched off automatically, the engine will
have to be restarted 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 shut-down
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.

Brakes and Parking
Introduction
This chapter contains information on the following subjects:
Handbrake
192
Parking
193
The wear and tear on the brake pads is dependent on the operating condi-
tions and driving style. In difficult conditions (e.g. urban, sporty driving), the
condition of the brakes should be checked between service intervals by a spe-
cialist garage.
Brake response can be slower if the brakes are covered in moisture or, in win-
ter, have a layer of ice or salt on them . The brakes should be cleaned and
dried by applying the brakes many times over »
.
Corrosion on the brake discs and dirt on the brake pads can occur if the vehicle
has been parked for a long period and if you do not make much use of the
braking system. The brakes are cleaned by applying the brakes several times
over »
.
191Starting-off and Driving

Before negotiating a long or steep gradient , reduce speed and shift down a
gear. As a result, the braking effect of the engine will be used, reducing the
load on the brakes. If, nevertheless, there is a need for additional braking, it
should be carried out at intervals.
Emergency braking warning - If it is necessary to brake hard, the system may
cause the brake lights to automatically flash, to alert the traffic behind.
New brake pads must first be““run in”” because these do not initially have the
best possible braking effect. Drive especially carefully for the first 200 km or
so.
If the brake fluid level is too low, it can cause faults in the braking system ;
the warning light will light up in the instrument cluster » page 33
,
Braking
system . If the warning light does not light up, yet the stopping distance is per-
ceived to be longer than before, the driving style should be adapted in view of
the unknown cause of the problem, and braking kept to a minimum - seek the
help of a specialist garage without delay.
The brake booster increases the pressure generated with the brake pedal. The
brake booster only operates when the engine is running.WARNING■ Greater physical effort for braking is required when the engine is switch-
ed off – risk of accident!■
During the braking procedure on a vehicle with manual transmission,
when the vehicle is in gear and at low revs, press the clutch pedal. Other-
wise, the functionality of the brake system may be impaired – risk of acci-
dent!
■
Do not depress the brake pedal, if there is no requirement to slow down.
This causes the brakes to overheat and can also result in a longer braking
distance and excessive wear - There is a risk of an accident!
■
Only brake 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.
■
Recommendations for new brake pads should be followed.
■
When stopping and parking, the parking brake should always be applied
firmly, otherwise the vehicle could move off - There is a risk of an accident!
■
If a front spoiler, full wheel trim, etc. is mounted retrospectively, it must
be ensured that the air supply to the front wheel brakes is not reduced.
Otherwise, the front brakes could be in danger of overheating – There is a
risk of an accident!
HandbrakeFig. 233
Handbrake
Read and observe on page 192 first.
The handbrake secures the vehicle against unwanted movement when stop- ping and parking.
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. 233 .
›
Move the lever right down while pressing the lock button.
The handbrake warning 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 handbrake warning is activated if the vehicle is driven
at a speed of over 5 km/h for more than 3 seconds.
WARNINGDisengage the handbrake completely. A handbrake which is only partially
disengaged can result in the rear brakes overheating. This can have a nega-
tive effect on the operation of the brake system – risk of accident!
Note
Push the armrest cover all the way back to the stop before applying the hand-
brake » page 79 .192Driving

During the first 1 000 km, the engine should not be charged with more than
3/4 of the maximum permitted engine revs and without the trailer.
From about 1 000 to 1 500 km the engine can be pushed up to the maximum
permitted engine speed.
Tips on economical driving
Fuel consumption depends on the driving style, road and weather conditions,
and similar such factors.
For an economical driving style, the following instructions must be observed. ▶ Avoid unnecessary acceleration and braking.
▶ Observe the recommended gear » page 42.
▶ Avoid full throttle and high speeds.
▶ Reduce idling.
▶ Avoid short distances.
▶ Ensure the correct tyre inflation pressure is maintained » page 261.
▶ Avoid unnecessary ballast.
▶ Remove the roof rack before driving if it is not needed.
▶ Only turn on electrical consumers (e.g. seat heating) for as long as necessary.
In the Infotainment menu
→
→
Conv. consumers
up to three consumers
who currently have the largest share of fuel consumption, can be displayed.
▶ Briefly ventilate before turning on the cooling system, do not use the cooling
system with the windows open.
▶ Do not leave windows open at high speeds.

■Ensure that no part of the leather is soaked through during cleaning and
that no water gets into the seams - There is risk of damaging the leather!
■ Do not clean the roof panelling with a brush – risk of damage to the surface
of the panelling. ■ Do not use leather cleaners, floor wax, shoe cream, stain remover or similar
agents on Alcantara ®
seat upholstery.
■ Some clothing fabrics (e.g. dark denim) do not have sufficient colour fast-
ness - this could lead to clearly visible discolouration on the upholstery. This
is not a defect in the fabric. ■ Sharp objects on garments (e.g. zips, rivets, sharp- edged belts) can dam-
age the upholstery fabrics in the vehicle. Such damage will not be recognised
as a justified complaint.■
Plastic parts
■ Do not attach scents or air fresheners to the dash panel – risk of damage to
the dash panel.
■
Windows
■ Do not attach any stickers to the filaments or glass antenna - there is risk
of damage.
■
