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.
100Driving
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
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

142
The correct fuel grades for your vehicle are specified on the inside of the fuel
filler flap » Fig. 150 on page 141 .
WARNING■
The operating instructions of the refuelling system must always be fol-
lowed.■
Do not smoke when refuelling and do not use a mobile phone.
■
The fuel and fuel vapours are explosive - it can be fatal!
CAUTION
■ Never drive until the fuel tank is completely empty! The irregular supply of
fuel can cause misfiring, which can result in damage to parts of the engine and
the exhaust system.■
Immediately remove any fuel that has spilled onto the vehicle's paintwork –
risk of paint damage.
■
If the vehicle was not purchased in the country where it was intended to be
operated, you should check whether the fuel specified by the manufacturer is
offered in the country where the vehicle will be operated. You should also per-
haps check whether the manufacturer has recommended a different fuel for
operation of the vehicle in the corresponding country. If no prescribed fuel is
available, then you must check whether it is permitted by the manufacturer to
operate the vehicle with another fuel type.

Coolant
Introduction
This chapter contains information on the following subjects:
Checking the coolant level
148
Replenishing
149
The coolant provides cooling for the motor.
It consists of water and coolant additive with additives that protect the cooling
system against corrosion and prevents furring.
The coolant additive in the coolant must be at least 40%.
The coolant additive may be increased to a maximum of 60%.
The correct mixing ratio of water and coolant additive is to be checked if nec-
essary by a specialist garage or is to be restored if necessary.
The description of the coolant is shown in the coolant expansion reservoir
» Fig. 155 on page 148 .
WARNINGThe engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en- gine compartment » page 143.■
The coolant is harmful to health.
■
Avoid contact with the coolant.
■
Coolant vapours are harmful to health.
■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurised!
■
When opening the end cover of the coolant expansion reservoir, cover it
with a cloth to protect your face, hands and arms from hot steam or hot
coolant.
■
If any coolant splashes into your eyes, immediately rinse out your eyes
with clear water and contact a doctor as soon as possible.
■
Always keep the coolant in the original container, safe from people who
are not completely independent, especially children - there is a danger of
poisoning!
■
If coolant is swallowed, consult a doctor immediately.
■
Never spill operating fluids over the hot engine - risk of fire.
CAUTION■ Do not continue if for some reason it is not possible to fill with coolant un-
der the current circumstances! Switch off the engine and seek assistance from
a specialist garage.■
If the expansion tank is empty, do not top up with coolant. The system could
ventilate - there is a risk of engine damage,
do not continue driving! Switch
off the engine and seek assistance from a specialist garage.
■
The concentration of coolant additive in the coolant must never be under
40%.
■
Over 60% of coolant additive in the coolant reduces the antifreeze protec-
tion and cooling effect.
■
A coolant additive that does not comply with the correct specification can
significantly reduce the corrosion protection of the cooling system.
■
Any faults resulting from corrosion may cause a loss of coolant and can con-
sequently result in major engine damage.
■
Do not fill the coolant above the mark
A
. » Fig. 155 on page 148
■
If an error occurs, leading to the engine overheating, the help of a professio-
nal garage is to be sought - there is a risk of serious engine damage occurring.
■
Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.
■
Never cover the radiator - there is a risk of the engine overheating.
