Information messages
101
The START STOPsystem (hereinafter referred to as the system) reduces
CO 2emissions and harmful emissions, and saves fuel.
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.
The system function depends on many factors. Some of them are down to the
driver, while others are systemic and can neither be influenced nor identified.
For this reason, the system may react differently in situations which seem
identical from the driver's perspective.
The system is automatically activated every time the ignition is switched on
(even when it has previously been manually deactivated with the button).
Note
If the engine has stopped due to the system, the ignition remains switched on.99Starting-off and Driving
OperationFig. 113
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 shown in the display when the vehicle comes to a halt
» Fig. 113 .
The engine is switched off automatically; when moving off, the ignition
process will be initiated automatically.
The engine is not switched off automatically.
Reasons 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.
Infotainment display
Information about the current status of the system can be displayed in the In-
fotainment display » Owner´s Manual Infotainment , chapter CAR - Vehicle set-
tings (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
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 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:
Information on braking
101
Handbrake
102
Parking
103WARNING■ Greater physical effort is required for braking when the engine is switch-
ed off – risk of accident!■
The clutch pedal must be actuated 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 could then start to move –
risk of accident!
■
Observe the recommendations on the new brake pads » page 106, New
brake pads .
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 on braking
Read and observe
and on page 101 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 service intervals.
101Starting-off and Driving
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 bake 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 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 32,
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.
Handbrake

The following message is shown in the information cluster display.
Release the handbrake!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.
102Driving
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!

Gearshift pattern of 5 gear or
6 gear manual gearbox
The gearshift pattern for the individual gear positions is shown on the gear
lever » Fig. 116 .
The gear shift indicator must be observed when changing gear » page 39.
Always depress the clutch pedal all the way down. This prevents uneven wear
to the clutch.
Engaging reverse gear
›
Stop the vehicle.
›
The clutch pedal must be fully depressed.
›
Move the shift lever to the idle position, switch and press down.
›
Move the shift lever fully to the left and then forward into the Rposition
» Fig. 116 .
The reversing lights will come on once the reverse gear is engaged, provided
the ignition is on.
WARNINGNever engage reverse gear when driving – risk of accident!
CAUTION
■ If not in the process of changing gear, do not leave your hand on the gear
shift lever while driving. The pressure from the hand can cause the gear shift
mechanism to wear excessively.■
When stopping on a slope, never try to hold the vehicle using the clutch and
the accelerator pedal – this may lead to damage to the clutch.
Pedals
The operation of the pedals must not be hindered under any circumstances!
103Starting-off and Driving
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. 117 .
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.
Selector lever lock
Fig. 118
Shift lock button
Read and observe and on page 104 first.
The selector lever is locked in modes P and N to prevent the forwards travel
mode from being selected accidentally and setting the vehicle in motion.
The selector lever is only locked 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)
›
Press the brake pedal and the lock button at the same time in the direction
of
1
» Fig. 118 .
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 172.
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 acci-
dentally selected.
Manual shifting (Tiptronic)
Fig. 119
Selector lever
Read and observe and on page 104 first.
Tiptronic mode makes it possible to manually shift gears on the selector lever. This mode can be selected both while stopping and while driving.
The currently selected gear is indicated in the » Fig. 117 on page 104 display.
The gear shift indicator must be observed when changing gear » page 39.

105Starting-off and Driving
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 155.
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 and
the like) 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.DriveGreen functionFig. 120
Shown in the infotainment dis-
play
The DriveGreen function (hereinafter referred to as DriveGreen) evaluates the
driving efficiency based on the information with regard to driving style. Useful
tips for reducing fuel consumption are also offered.

107Starting-off and Driving
›Therefore, always determine the depth of the water before driving through
water.
The water level must not reach above the web of the lower beam » Fig. 121.›
Do not drive any faster than at a walking speed.
At a higher speed, a water wave can form in front of the vehicle which can
cause water to penetrate into the engine's air induction system or other parts
of the vehicle.
›
Never stop in the water, do not reverse and do not switch the engine off.
CAUTION
■ Should water penetrate into the intake system of the engine, there is a
threat of serious damage being incurred by the engine parts!■
When driving through water, some vehicle parts such as chassis, electrics or
transmissions can be severely damaged.
■
Oncoming vehicles can generate water waves which can exceed the permis-
sible water level for your vehicle.
■
Potholes, mud or rocks can be hidden under the water, making it difficult or
impossible to drive through water.
■
Do not drive through salt water, as the salt can cause corrosion. A vehicle
coming into contact with salt water is to be thoroughly rinsed with fresh wa-
ter.
Assist systems
General information
Introduction
WARNINGThe following general information regarding the use of assistance systems
must be observed.■
The assistance systems only serve to support the driver and do not re-
lieve the driver of the responsibility for driving the vehicle.
■
The increased safety provision, as well as the increased occupant protec-
tion provided by the assistance systems must not tempt you to take risks -
risk of accident!
■
Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions.
■
The assistance systems have physical and system-related limitations. For
this reason, the driver may experience some undesired or delayed system
responses in certain situations. You should therefore always be alert and
ready to intervene!
■
Only enable, disable or set the assistance systems so that you have the
car fully under control in every traffic situation - risk of accident!
