four wheel drive MERCEDES-BENZ SLK300 2010 R171 Owner's Manual

Restart the TPMS after adjusting the tire
inflation pressure to the inflation pressure
recommended for the vehicle operating
condition. Tire inflation pressure should only
be adjusted on cold tires. Observe the
recommended tire inflation pressure on the
Tire and Loading Information placard on the
driver’s door B-pillar. Some vehicles may have
supplemental tire inflation pressure
information for driving at high speeds or for
vehicle loads less than the maximum loaded
vehicle condition. If such information is
provided, it can be found on the inside of the
fuel filler flap.
X
Using the Tire and Loading Information
placard on the driver’s door B-pillar
(Y page 205) or the supplemental tire
inflation pressure information on the inside
of the fuel filler flap, make sure the tire
inflation pressure of all four tires is correct.
X Switch on the ignition.
X Press button V or U on the
multifunction steering wheel repeatedly
until the standard display appears in the
multifunction display ( Y page 96).
X Press button & or * repeatedly until
you see the current inflation pressures for
each tire appear in the display or the
following message appears in the
multifunction display:
Tire pressure is
only displayed
after driving for
a few minutes.
X Press the reset button (Y page 92).
The following message will appear in the
multifunction display:
Restart tire
pressure monitor?
X If you wish to confirm: Press button
W.
The following message will appear in the
multifunction display:
Tire Pressure Monitor
Restarted After driving a few minutes the system
verifies that the current tire inflation
pressures are within the system’s specified
range. Afterwards the current tire inflation
pressures are accepted as reference values
and then monitored.
X If you wish to cancel: Press button X.
i When the wheel positions have been
changed, the inflation pressure of a tire
may be displayed for the wrong position
temporarily. After driving for a few minutes,
the inflation pressure will be shown for the
correct position. Maximum tire inflation pressure
G
Warning!
Never exceed the maximum tire inflation
pressure. Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are
more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes etc. i

based on three performance factors:
treadwear

resistance =.
Although not a Government of
Canada requirement, all tires made for sale in
North America have these grades branded on
the sidewall.
i For illustration purposes only. Actual data
on tires are specific to each vehicle and
may vary from data shown in above
illustration.
Quality grades can be found, where
applicable, on the tire sidewall between tread
shoulder and maximum section width. For
example: Treadwear Traction Temperature
200 AA A
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
U.S. Government test course. For example, a
tire graded 150 would wear one and one-half
(1 1
/ 2) 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 climate.
Traction G
Warning!
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cornering, hydroplaning, or peak traction
characteristics.
The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions on
specified

government test surfaces of asphalt
and concrete. A tire marked C may have poor
traction performance. G
Warning!
If ice has formed on the road, tire traction will
be
substantially reduced. Under such weather
conditions, drive, steer and brake with
extreme caution.
The safe speed on a wet, snow covered or icy
road is always lower than on a dry road.
You should pay particular attention to the
condition of the road whenever the outside
temperature is close to the freezing point.
Mercedes-Benz recommends winter tires
(Y page 219) with a minimum tread depth of
approximately 1
/ 6 in (4 mm) on all four wheels
for the winter season to ensure normal
balanced handling characteristics. On
packed snow, they can reduce your stopping
distance compared to summer tires.
Stopping distance, however, is still
considerably greater than when the road is
not covered with snow or ice. Exercise
appropriate caution.
! Avoid spinning of a drive wheel. This may
cause serious damage to the drivetrain
which is not covered by the Mercedes-Benz
Limited Warranty.
Temperature G
Warning!
The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause Tires and wheels
