Safety information

Caution

Vehicle features and options

This chapter describes model-specific

equipment, systems, and functions that are

currently available, or may become available

in the future, even if they are not present in

the vehicle.

The use of poor-quality fuels may result

in harmful engine deposits or damage.

Additionally, problems relating to drivabil-

ity, starting and stalling, especially under

certain environmental conditions such as

high ambient temperature and high alti-

tude, may occur.

Additional information:

Vehicle equipment, refer to page 8.

If drivability problems are encountered,

we recommend switching to a high quality

gasoline brand and a higher octane grade

— AKI number — for a few tank fills. To

avoid harmful engine deposits, it is highly

recommended to purchase gasoline from

Top Tier retailers.

Fuel recommendation

General information

Depending on the region, many filling sta-

tions sell fuel that has been customized to

winter or summer conditions. Fuel that is

available in winter, for instance helps make

a cold start easier.

Failure to comply with these recommenda-

tions may result in the need for additional

maintenance.

Gasoline

Warning

General information

Even small quantities of the wrong fuel or

wrong fuel additives can damage the fuel

system and engine. Furthermore, the cat-

alytic converter can be permanently dam-

aged. There is a risk of injury and risk

of damage to property. Do not refuel or

add the following in the case of gasoline

engines:

For the best fuel efficiency, the gasoline

should be sulfur-free or very low in sulfur

content.

Fuels that are marked on the gas pump as

containing metal must not be used.

Fuels with a maximum ethanol content of

10 %, i.e., E10, may be used for refueling.

–

Leaded gasoline.

The power and consumption specifications

correspond to operation with 98 RON E10

fuel.

Metallic additives, for instance man-

ganese or iron.

Knocking noises and driving/acoustic prob-

lems may occur when using minimum qual-

ity fuel, e.g., 87 AKI, or fuel with an ethanol

content of more than 10 % to max. 15 %.

These have no effect on the engine service

life.

Do not turn on standby after refueling

with the wrong fuel. Contact an authorized

service center or another qualified service

center or repair shop.
