2005 MERCEDES-BENZ SLR CLASS fuel pressure

369 Technical data
Rims and tires
Rims and tires
Only use tires and rims which have been
specifically developed for your vehicle and
tested and approved by Mercedes-Benz.
Other tires and rims can have detrimental
effects, such as

Poor handling characteristics


Increased noise


Increased fuel consumption
!Moreover, tires and rims not approved
by Mercedes-Benz may, under load,
exhibit dimensional variations and dif-
ferent tire deformation characteristics
that could cause them to come into
contact with the vehicle body or axle
parts. This may result in damage to the
tires or the vehicle.
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Center. A placard with
the recommended tire inflation pres-
sures is located on the driver’s door
B-pillar. Some vehicles may have sup-
plemental tire pressure information for
driving at high speeds (
page 263) or
for vehicle loads less than the maxi-
mum loaded vehicle condition. If such
information is provided, it can be found
on the placard located on the inside of
the fuel filler flap. The tire pressure
should be checked regularly and
should only be adjusted on cold tires.
Follow tire manufacturer’s mainte-
nance recommendation included with
vehicle.

Fuels, coolants, lubricants, etc.
Using mixtures of ethanol and methanol is
not allowed. Gasohol, which contains
10% ethanol and 90% unleaded gasoline,
can be used.
These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc.
Gasoline additives
A major concern among engine
manufacturers is carbon build-up caused
by gasoline. Mercedes-Benz recommends
only the use of quality gasoline containing
additives that prevent the build up of
carbon deposits.
After an extended period of using fuels
without such additives, carbon deposits
can build up especially on the intake valves
and in the combustion area, leading to
engine performance problems such as:

Warm-up hesitation


Unstable idle


Knocking/pinging


Misfire


Power lossIn areas where carbon deposits may be
encountered due to lack of availability of
gasolines which contain these additives,
Mercedes-Benz recommends the use of
additives approved by us for use on
Mercedes-Benz vehicles. Refer to Factory
Approved Service Products pamphlet for a
listing of approved product(s). Follow
directions on product label.
Do not blend any specific fuel additives
with fuel. This only results in unnecessary
cost and may be harmful to engine
operation.
Damage or malfunction resulting from
poor fuel quality or from blending
additional fuel additives other than those
tested and approved by us for use on
Mercedes-Benz vehicles listed in the
Factory Approved Service Products
pamphlet are not covered by the
Mercedes-Benz Limited Warranty.

Head-thorax airbag
Installed in the doors, these airbags
protect occupants during side impact
collisions exceeding a preset thresh-
old. Unlike normal side airbags,
head-thorax airbags are also designed
to provide protection for the head area.Instrument cluster
The displays and indicator/warning
lamps in the driver’s field of vision, in-
cluding the tachometer, speedometer,
engine temperature and fuel gauge.
Kickdown
Depressing the accelerator past the
point of resistance shifts the transmis-
sion down to the lowest possible gear.
This very quickly accelerates the vehi-
cle and should not be used for normal
acceleration needs.

umber)
The Motor Octane Number for gasoline
as determined by a standardized
method. It is an indication of a gaso-
line's ability to resist undesired detona-
tion (knocking). The average of both
the MON (Motor Octane Number) and
RON (Research Octane Number) is
posted at the pump, also known as
ANTI-KNOCK INDEX.
Multifunction display
Two display fields in the instrument
cluster used to present information
provided by the control system.
Multifunction steering wheel
Steering wheel with buttons for operat-
ing the control system.
