Engine oil temperature*
The general operating temperature is between
1607/706 and approx. 3407/1706.
If the engine oil temperature is too high, a mes-
sage appears in the Control Display.
Fuel gauge
Fuel tank capacity: approx. 18.5 US gal/
70 liters, including the reserve capacity of
approx. 2.6 US gal/10 liters. You will find infor-
mation on refueling on page194.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
After the reserve quantity has been reached, a
message briefly appears on the Control Display;
the remaining range is shown in the computer.
Below a range of approx. 30 miles/50 km, the
message remains on the Control Display.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, otherwise engine functions are not
ensured and damage can occur.<
Computer
Displays in instrument cluster
Press the button on the turn signal lever.
The following information is displayed in the
specified order:
>Cruising range
>Average speed
>Average fuel consumption
>No information
Cruising range
Displays the estimated cruising range available
with the remaining fuel. The range is projected
based on the driving style over the last 20 miles/
30 km.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, otherwise engine functions are not
ensured and damage can occur.<
Average speed
Periods with the vehicle parked and the engine
switched off are not included in the calculations
of average speed.
To reset average speed: press BC button on
turn signal lever for approx. 2 seconds.
Average fuel consumption
The average fuel consumption is calculated for
the time during which the engine is running.
To reset average fuel consumption: press BC
button on turn signal lever for approx. 2 sec-
onds.

Things to remember when driving

Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. To ensure that your vehicle contin-
ues to provide optimized economy of operation
throughout an extended service life, we request
that you devote careful attention to the follow-
ing section.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at changing engine and driving speeds,
however do not exceed 4,500 rpm or 100 mph/
160 km/h.
Avoid full-throttle operation and use of the
transmission's kickdown mode during these
initial miles.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive reservedly during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive in a reserved manner during
this break-in period.
Clutch
The function of the clutch is only at its opti-
mized level after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
Observe the break-in instructions again if com-
ponents mentioned above must be replaced
after subsequent driving operation.
Saving fuel
The fuel consumption of your vehicle depends
on various factors. Through a few simple steps,
your driving style, and regular maintenance, you
can have a positive influence on your fuel con-
sumption and environmental impact.
Removing unnecessary cargo
Additional weight increases fuel consumption.
Removing add-on parts after use
Remove unneeded auxiliary mirrors, roof or rear
luggage racks after use. Add-on parts attached
to the vehicle impede the aerodynamics and
increase the fuel consumption.
Closing windows and glass sunroof
An open glass sunroof or open windows like-
wise increase the drag coefficient and therefore
the fuel consumption.
Checking tire inflation pressures
regularly
Check and correct the tire inflation pressure as
needed at least twice a month and before long
trips.
An insufficient tire inflation pressure increases
the rolling resistance and thus increases the
fuel consumption and tire wear.
Driving off immediately
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive at a moderate engine
speed. This is the fastest way for the cold
engine to reach its operating temperature.

Refueling
194
Refueling
Switch off the engine before refueling;
otherwise no fuel can be filled into the
tank and a message is displayed.<
When handling fuel, always observe all
applicable precautionary measures and
regulations. Never transport reserve fuel con-
tainers in the vehicle. They can leak and cause
an explosion or a fire in an accident.<
Fuel filler flap
To open and close: briefly press the rear edge of
the fuel filler flap.
Unlocking manually
In the event of an electrical malfunction, you can
release the fuel filler flap manually:
In the luggage compartment, pull the knob with
the gas pump symbol on the right side panel.
Observe the following when refueling
When handling fuels, follow the safety
precautions posted at the filling station. Otherwise, there is a danger of personal injury
and property damage.<
Place the fuel filler cap in the bracket attached
to the fuel filler flap.
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid raising the filler
nozzle during refueling; otherwise this
>results in premature pump shutoff
>can lead to reduced efficiency in the fuel-
vapor recovery system
The fuel tank is full when the filler nozzle clicks
off the first time.
Fuel tank capacity
Approx. 18.5 US gal/70 liters, including approx.
2.6USgal/10liters reserve capacity.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, otherwise engine functions are not
ensured and damage can occur.<
Fuel filler cap
Closing
Insert the cap and turn it clockwise until there is
a clearly audible click.
Do not crush the band attached to the
cap; otherwise, the cap may not properly
seal and fuel vapors can escape.<
A message
* is displayed if the cap is loose or
missing.
