Notes on the oil level Depending on the driving style, the vehicle
consumes up to 0.9 US qt (
0.8l) of oil over a
distance of 600 miles (1000km). The oil
consumption may be higher than this when
the
vehicle is new or if you frequently drive at
high engine speeds.
Checking the oil level using the oil
dipstick Example
X
Park the vehicle on a level surface.
To check the oil level with the engine at
operating temperature, switch the engine
off and
wait for approximately five minutes.
X Pull oil dipstick : out
of the dipstick guide
tube.
X Wipe off oil dipstick :.
X Slowly slide oil dipstick : into the guide
tube to the stop, and take it out again.
If the level is between MIN mark = and
MAX mark ;, the oil level is correct.
X Add oil if necessary. Engine compartment

Important safety notes G
WARNING
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
personal injury.
Never allow sparks, flames or smoking
materials near gasoline.
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and any skin or clothing
contact.
Direct skin contact with fuels and the
inhalation of
fuel vapors are damaging to your
health.
Gasoline Fuel grade
!
Do not
use diesel to refuel vehicles with a
gasoline engine. Even small amounts of the
wrong fuel result in damage to the fuel
system and engine.
! You should only refuel with unleaded
premium-grade gasoline as this avoids
damaging the catalytic converter.
If engine running problems are apparent,
have the cause checked immediately and
repaired. Excess unburned fuel can
otherwise enter the catalytic converter,
leading to overheating and possibly
causing a fire. !
To ensure the longevity and full
performance of the engine, only premium-
grade unleaded gasoline may be used.
If there is no premium-grade unleaded
gasoline available and regular unleaded
gasoline must
be used, please observe the
following precautions:
R only fill the fuel tank to half full with
regular unleaded gasoline and fill the rest
with premium-grade unleaded gasoline
as soon as possible.
R do not drive at the maximum speed.
R avoid sudden acceleration.
R if the vehicle is carrying a light load, e.g.
two passengers without luggage, do not
allow the engine to rev above 3000 rpm.
R if the vehicle is fully loaded or is being
operated in mountainous terrain, do not
depress the accelerator pedal further
than Ô of the pedal travel.
Only refuel using unleaded gasoline with a
minimum octane rating of 91.
Reformulated Gasoline (RFG) and/or
unleaded gasoline with additives can be used.
The concentration of additives in the fuel
must, however, remain below 10 %, such as:
R Ethanol
R TAME
R ETBE
R IPA
R TBA
For MTBE, the concentration should not
exceed 15 %.
The concentration of methanol in gasoline
including other additives must not exceed
3 %.
Using mixtures of methanol and ethanol is not
permitted. Gasohol, a mixture of 10 % ethanol
and 90 % unleaded gasoline, can be used. Service products and filling capacities
