Information messages
105
The START-STOPsystem (hereinafter referred to only as system) saves fuel
and reduces harmful emissions and CO 2 discharge.
If the system determine that the engine is not needed when the vehicle stops
(e.g. at the traffic lights), it turns off the engine and starts it again when mov-
ing off.
Operation
Fig. 114
Display
For the system-dependent automatic engine shut-down when stopping to op-
erate, the following conditions must be met.
For vehicles with manual transmission , the shift lever is in the neutral po-
sition and the clutch pedal is not depressed.
For vehicles with automatic transmission the brake pedal is to be de-
pressed.
The driver's door is closed.
104Driving
Downloaded from www.Manualslib.com manuals search engine The driver has fastened the seat belt.
The bonnet is closed.
The driving speed exceeded 4 km/h after the last stop.
No trailer is coupled.
Some additional conditions for the system to function cannot be either influ-
enced or recognised by the driver. Therefore, the system can react differently
in situations which are identical from the driver's view.
The information as to whether the conditions are met for the automatic en-
gine shut-off, are shown in the display » Fig. 114.
The motor is automatically switched off.
The engine is not turned off when you stop (the conditions for the auto-
matic motor shut-down are not met).
Reasons for the engine running
Running the engine can be essential, 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 indoor 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.
Infotainment display
Information about the current status of the system can be displayed in the In-
fotainment display » operating instructions for Infotainment , chapter CAR -
Vehicle settings (CAR button) .
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 sys-
tem.■
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.

Brakes and parking
Introduction
This chapter contains information on the following subjects:
Information for braking

Handbrake
107
Parking
107WARNING■ Greater physical effort is required for braking when the engine is switch-
ed off – risk of accident.■
The clutch pedal must be depressed when braking on a vehicle with man-
ual transmission, when the vehicle is in gear and at low revs. Otherwise,
the functionality of the brake system may be impaired – risk of accident!
■
When leaving the vehicle never leave persons leave unattended in the
vehicle who could release the brake. The vehicle might then move off – risk
of accident.
■
Observe the recommendations on the new brake pads » page 111.
CAUTION
Never let the brakes slip with light pressure on the pedal if braking is not nec-
essary. This causes the brakes to overheat and can also result in a longer brak-
ing distance and excessive wear.
Information for braking
Read and observe
and on page 106 first.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driv-
ing style.
The brake pads wear more quickly if a lot of journeys are completed in towns
and over short distances or if a very sporty style of driving is adopted.
Under these severe conditions , the thickness of the brake pads must also be
checked by a specialist garage between services.
Wet roads or road salt
The performance of the brakes can be delayed as the brake discs and brake
pads may be moist or have a coating of ice or layer of salt on them in winter.
The brakes are cleaned and dried by applying the brakes several times »
.
Corrosion
Corrosion on the brake discs and dirt on the brake pads 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 »
.
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 control unit for the braking system con-
siders the situation to be dangerous for the following traffic, the brake light
flashes automatically.
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.
Fault in the brake system
If it is found that the braking distance has suddenly become longer and that
the brake pedal can be depressed further, there may be a fault in the brake
system.
Visit a specialist garage immediately and adjust your style of driving appropri-
ately as you will not know how great the damage is.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system.
The fluid level is monitored electronically » page 32,
Brake system
.
Brake booster
The brake booster increases the pressure generated with the brake pedal. The brake booster only operates when the engine is running.
106Driving
Downloaded from www.Manualslib.com manuals search engine 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.

RELEASE HANDBRAKE
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!

lector lever - there is a risk of accident!■
Never shift the selector lever to R or P modes when driving – there is a
risk of an accident.
■
If the vehicle is in the mode selected D, S , R or Tiptronic and the engine
stops when at idle speed, then the brake pedal must be pressed. Even
when the engine is idling, power transmission is never completely interrup-
ted – the vehicle will creep.
■
When leaving the vehicle, the selector lever is always to be put in the P
mode. Otherwise the vehicle could then start to move and potentially cause
an accident.
CAUTION
■ If the selector lever is moved to mode N while driving, the accelerator pedal
must be released and you will need to wait until the engine has reached its
idling speed before moving the selector lever to a forward driving mode again.■
When the outdoor temperature is below -10 ° C, the selector lever, when
starting, must always be in P mode.
■
When stopping on a slope, never try to keep the vehicle in position by using
the accelerator pedal – this may lead to gear damage.
Note
After the ignition is switched off, the ignition key can only be withdrawn if the
selector lever is in the position P.
Modes and use of selector lever

Selector lever/display
Read and observe and on page 109 first.
When the ignition is switched on, the gearbox mode and the currently selected
gear are indicated in the display » Fig. 118.
The following modes can be selected with the selector lever » Fig. 118.
P
– Parking mode
The driven wheels are locked mechanically in this mode.
Parking mode must only be selected when the vehicle is stationary.
R
- Reverse gear
Reverse gear can only be engaged when the vehicle is stationary and the en-
gine is at idling speed.
N
- Neutral
Power transmission to the drive wheels is interrupted in this mode.
D

S
- mode for driving forward (Normal program) / mode for driving
forward (Sport program)
The system switches from one mode to the other by moving the selector lever
into the spring-loaded position
» Fig. 118 .
In mode D or S, the forward gears are shifted automatically depending on the
engine load, the operation of the accelerator pedal, the vehicle speed, and the
selected driving mode .
In mode S, the forward gears are shifted automatically up and down at higher
engine speeds than in mode D.

Shift lock button
Read and observe and on page 109 first.
The selector lever is locked in the P and N modes to prevent the forwards trav-
el mode from being selected accidentally and setting the vehicle in motion.
The selector lever is locked only when the vehicle is stationary and at speeds
up to 5 km/h.
The selector lever lock is indicated by the illumination of the warning light.
The selector lever is not locked when quickly moving across the position N
(e.g. from R to D/S ). This, for example, helps to rock out a vehicle that is stuck,
e.g. in a bank of snow. The selector lever lock will engage if the lever is in posi-
tion N for more than approx. 2 seconds without the brake pedal being de-
pressed.
Releasing selector lever from mode P or N (selector lever lock)

Just depress the brake pedal, if you would like to change from the mode N to
D/S .
Defective selector lever lock
If the selector lever lock is defective or its power supply is interrupted (e.g. dis-
charged vehicle battery, faulty fuse), the selector lever can no longer be moved
out of position P in the normal manner and the vehicle can no longer be driven.
The selector lever must be emergency released » page 179.
Note
If you want to move the selector lever from mode P to mode D/S or vice versa,
move the selector lever quickly. This prevents modes R or N from being selec-
ted accidentally.Manual shifting (Tiptronic)Fig. 120

Note
■
It may be advantageous to use manual gear shifting when driving downhill,
for example. Shifting to a lower gear reduces the load on the brakes and hence
brake wear » page 106.■
When accelerating, the gearbox automatically shifts up into the higher gear
just before the maximum permissible engine speed is reached.
■
If a lower gear is selected, the gearbox does not shift down until there is no
risk of the engine overrevving.

Kickdown
The kickdown function allows you to achieve maximum acceleration by your vehicle while driving.
When the accelerator pedal is fully depressed, the kickdown function is activa-
ted in any forward driving mode.
The gearbox shifts down one or more gears depending on the vehicle speed
and engine speed, and the vehicle accelerates.
The gearbox does not shift up into the highest gear until the engine has
reached its maximum revolutions for this gear range.
WARNINGRapid acceleration, particularly on slippery roads, can lead to loss of control
of the vehicle – there is a risk of an accident.
Running-in and economical driving
Introduction
This chapter contains information on the following subjects:
Running-in

Tips for economical driving
111
DriveGreen function
112The fuel consumption, degree of pollution and vehicle wear depend on driving
style, road condition, weather conditions and the like.
Running-in
Driving in the engine
The engine has to be run in during the first 1 500 kilometres. During this peri-
od, the driving style decides on the quality of the driving-in process.
During the first 1,000 km ,we recommend not driving faster than 3/4 of the
maximum permissible engine speed, not to drive at full throttle and not to use
a trailer.
In the range of 1,000 to 1,500 kilometres, the engine load can be increased up
to the maximum permitted engine speed.
New tyres
New tyres have to be “run in” since they do not offer optimal grip at first.
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.
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.
Change gear in an energy saving and timely manner
Observe the recommended gear » page 39.
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.

This section of the manual contains important information on preventing dam-
age to the vehicle while driving.
Driving Tips
Only drive on such roads and in such terrain, which match the vehicle parame-
ters » page 192 , Technical data as well as your driving skills.
The driver is always responsible for deciding whether the vehicle can handle
travelling in the given terrain.WARNING■ Always adjust your driving to the current terrain and weather conditions.
Excessive speed or incorrect driving manoeuvres can cause damage to the
vehicle and lead to serious injuries.■
Combustible objects such as dry leaves or twigs caught under the base of
the vehicle could ignite on hot vehicle parts - risk of fire!
CAUTION
■ Pay attention to the ground clearance of the vehicle! When driving over ob-
jects which are larger than the ground clearance, the vehicle can get damaged.■
Any objects that get trapped under the vehicle floor must be removed as
soon as possible. These objects can damage the fuel lines, the brake system,
seals and other parts of the vehicle.
■
Drive slowly in unknown terrain and watch out for unexpected obstacles,
such as potholes, rocks, stumps, etc.
■
Check up on confusing sections of unpaved roads before travelling on them
and consider whether such travelling is possible without risk.
