Mercedes-Benz SLR McLaren. Operator's Manual.

Winter driving
Before the onset of winter, have your
vehicle winterized at an authorized
Mercedes-Benz Center. This service
includes:
Check of anticorrosion and antifreeze
concentration.
Addition of cleaning concentrate to the
water of the windshield and headlamp
cleaning system. Add MB Concentrate
“S” to a premixed windshield washer
solvent/antifreeze which is formulated
for below freezing temperatures
( page 383).
Battery test. Battery capacity drops
with decreasing ambient temperature.
A well charged battery helps to make
sure that the engine can be started,
even at low ambient temperatures.
Tire change. Mercedes-Benz recommends
M+S rated radial-ply tires with a
minimum tread depth of approximately
1
/6 in (4 mm) on all four wheels for the
winter season.
Winter tires*
!
A wheel change should only be carried
out at an authorized Mercedes-Benz
Center. Otherwise there is a danger of
damaging the vehicle by jacking it up
incorrectly.
Always use winter tires at temperatures
below 45°F (7°C) and whenever wintry
road conditions prevail. Not all M+S rated
tires provide special winter performance.
Make sure the tires you use show the
mountain/snowflake.marking on the
tire sidewall. These tires meet specific
snow traction performance requirements
of the Rubber Manufacturers Association
(RMA) and the Rubber Association of Canada
(RAC) and have been designed specifically
for use in snow conditions. Use of
winter tires is the only way to achieve the
maximum effectiveness of the ABS and
ESP ® in winter operation.
Operation
Winter driving
For safe handling, make sure that all
mounted winter tires are of the same make
and have the same tread design.
Warning! G
Winter tires with a tread depth under 1 / 6 in
(4 mm) must be replaced. They are no
longer suitable for winter operation.
Always observe the speed rating of the
winter tires installed on your vehicle. If the
maximum speed for which your tires are
rated is below the speed rating of your
vehicle, you must place a notice to this
effect where it will be seen by the driver.
Such notices are available from your tire
dealer or from any authorized
Mercedes-Benz Center.
