Driving and operating155Side blind spot alert is active from
speeds of 6 mph up to 87 mph.
Driving faster than 87 mph
deactivates the system, indicated by
low lighting warning symbols B in
both exterior mirrors. Reducing the
speed again will extinguish the
warning symbols. If a vehicle is then
detected in the blind zone, the
warning symbols B will illuminate as
normal on the relevant side.
When the vehicle is started, both
exterior mirror displays will briefly
illuminate to indicate that the system
is operating.
The system can be activated or
deactivated in the Info-Display.
Vehicle personalisation 3 99.
Deactivation is indicated by a
message in the Driver Information
Centre.
Detection zones The detection zones start at the rear
bumper and extend approx. three metres rearwards and to the sides.
The height of the zone is between
approx. 0.5 metres and two metres off
the ground.The system is deactivated if the
vehicle is towing a trailer.
Side blind spot alert is designed to
ignore stationary objects, e.g.
guardrails, posts, curbs, walls and
beams. Parked vehicles or oncoming
vehicles are not detected.
Fault
Occasional missed alerts can occur
under normal circumstances and will
increase in wet conditions.
Side blind spot alert does not operate when the left or right corners of the
rear bumper are covered with mud,
dirt, snow, ice, slush, or in heavy
rainstorms. Cleaning instructions
3 208.
In the event of a fault in the system or if the system does not work due to
temporary conditions, a message is
displayed in the Driver Information
Centre. Seek the assistance of a
workshop.Fuel
Fuel for petrol engines Only use unleaded fuel that complies
with European standard EN 228 or
equivalent.
The engine is capable of running with
fuel that contains up to 10% ethanol
(e.g. named E10).
Use fuel with the recommended octane rating. A lower octane rating can reduce engine power and torque
and slightly increases fuel
consumption.Caution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.

156Driving and operatingCaution
Use of fuel that does not comply toEN 228 or equivalent can lead todeposits or engine damage.
Caution
Use of fuel with a lower octane
rating than the lowest possible
rating could lead to uncontrolled combustion and engine damage.
The engine-specific requirements
regarding octane rating are given in
the engine data overview 3 220. A
country-specific label at the fuel filler
flap can supersede the requirement.
Fuel additives outside Europe
Fuel should contain detergent
additives that help prevent engine
and fuel system deposits from
forming. Clean fuel injectors and
intake valves will allow the emission
control system to work properly.
Some fuel does not contain sufficient
quantities of additive to keep fuel
injectors and intake valves clean.
To make up for this lack of
detergency, add Fuel System
Treatment PLUS to the fuel tank at
every engine oil change or every
10,000 miles, whichever occurs first. It is available at your workshop.
Fuels containing oxygenates such as
ethers and ethanol, as well as
reformulated fuel, are available in
some cities. If these fuels comply with the previously described
specification, then they are
acceptable to use. However, E85
(85% ethanol) and other fuels
containing more than 15% ethanol
must be used only in FlexFuel
vehicles.Caution
Do not use fuel containing
methanol. It can corrode metal
parts in the fuel system and also
damage plastic and rubber parts.
This damage would not be
covered by the vehicle warranty.
Some fuels, mainly high octane
racing fuels, can contain an octane
enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). Do not use fuels or fuel additives with MMT as they can
reduce spark plug life and affect
emission control system
performance. The malfunction
indicator light Z may turn on 3 86. If
this occurs, seek the assistance of a
workshop.
Fuel for liquid gas operation Liquid gas is known as LPG
(Liquefied Petroleum Gas) or under
its French name GPL (Gaz de Pétrole
Liquéfié). LPG is also known as
Autogas.
LPG consists mainly of propane and
butane. The octane rating is between 105 and 115, depending on the
butane proportion. LPG is stored
liquid at around five to ten bar
pressure.
The boiling point depends on the
pressure and mixing ratio. At ambient
pressure, it is between -42 °C (pure
propane) and -0.5 °C (pure butane).
