Refueling
Fuel cap
Opening
1.
Briefly press the rear edge of the fuel filler
flap. 2.
Turn the fuel cap counterclockwise. 3.
Place the fuel cap in the bracket attached to
the fuel filler flap. Closing
1.
Fit the cap and turn it clockwise until you
clearly hear a click.
2. Close the fuel filler flap. Do not pinch the retaining strap
Do not pinch the retaining strap attached
to the cap; otherwise, the cap cannot be closed
properly and fuel vapors can escape.
A message is displayed if the cap is loose or
missing.◀
Manually unlocking fuel filler flap
In the event of an electrical malfunction, for ex‐
ample. Pull the green knob with the fuel pump symbol.
This releases the fuel filler flap.
Observe the following when
refueling
The fuel tank is full when the filler nozzle clicks
off the first time.
Handling fuels
Obey
safety regulations posted at the gas
station.◀
Fuel tank capacity
Gasoline engine Fuel tank capacity: approx.
21.6 US gal/82 liters.
Refuel promptly
Refuel below a range of 30 miles/50 km;
otherwise, engine functions are not ensured and
damage may occur.◀ Seite 242

Refueling

Fuel
Fuel quality
Refuel with unleaded fuel only
Do not use leaded fuel as this would per‐
manently damage the catalytic converter.
◀
Do not refuel with ethanol
Do not refuel with E85, i.e., fuel with an
ethanol content of 85 %, or with Flex Fuel, as this
would damage the engine and fuel supply sys‐
tem.◀
Required fuel
Super premium gasoline/AKI 91
This gasoline is highly recommended.
Gasoline with lower AKI
However, you may also use gasoline with less
AKI.
The minimum AKI Rating is 89.
If you use gasoline with this minimum AKI Rat‐
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no effect on the engine life.
Minimum fuel grade
Do not use any gasoline below the mini‐
mum specified fuel grade; otherwise, engine
damage may occur.◀
Use high-quality brands
Field experience has indicated significant differ‐
ences in fuel quality: volatility, composition, ad‐
ditives, etc., among gasolines offered for sale in
the United States and Canada.
Fuels containing up to and including 10 % etha‐
nol or other oxygenates with up to 2.8 % oxygen
by weight, that is, 15 % MTBE or 3 % methanol
plus an equivalent amount of co-solvent, will not
void the applicable warranties with respect to
defects in materials or workmanship. Minimum fuel grade
The
use of poor-quality fuels may result in
driveability, starting and stalling problems es‐
pecially under certain environmental conditions
such as high ambient temperature and high al‐
titude.
Should you encounter driveability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may result in unscheduled maintenance.◀ Seite 243

Wheels and tires
Tire inflation pressure
Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:
▷
The service life of the tires.
▷ Road safety.
▷ Driving comfort.
Checking the pressure
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been
parked for at least 2 hours. When the tires
are warm, the tire inflation pressure is higher.
Check the tire inflation pressure regularly
Regularly check the tire inflation pressure
and correct it as needed: at least twice a month
and before a long trip. If you fail to observe this
precaution, you may be driving on tires with in‐
correct tire pressures, a condition that may not
only compromise your vehicle's driving stability,
but also lead to tire damage and the risk of an
accident.◀
After correcting the tire inflation pressure, rein‐
itialize the Tire Pressure Monitor.
Pressure specifications
The tire inflation pressure table, refer to
page 244, contains all pressure specifications
for the specified tire sizes at the ambient tem‐
perature. Pressure specifications apply to ap‐
proved tire sizes and recommended tire brands.
This information can be obtained from your
service center.
To identify the correct tire inflation pressure,
please note the following:
▷ Tire sizes of your vehicle.
▷ Vehicle load.
▷ Maximum allowable driving speed. Tire inflation pressures up to 100 mph/
160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum

driving comfort, note the pressure val‐
ues in the tire inflation pressure table, refer to
page 244, and adjust as necessary. These pressure values can also be found on the
tire inflation pressure label on the driver's door
pillar.
Maximum permissible speed
Do not exceed 100 mph/160 km/h; other‐
wise, tire damage and accidents may result.

DOT code: DOT xxxx xxx 3510

Tires
with DOT codes meet the guidelines of the
U.S. Department of Transportation.
Tire age
DOT … 3510: the tire was manufactured in the
35th week in 2010.
Recommendation
Regardless of wear, replace tires at least every
6 years.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width.
For example: Treadwear 200; Traction AA;
Temperature A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to Federal
Safety Requirements in addition to these
grades.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov‐
ernment test course. For example, a tire graded
150 would wear one and one-half, 1 g, times as
well on the government course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, however,
and may depart significantly from the norm due
to variations in driving habits, service practices
and differences in road characteristics and cli‐
mate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
