WARNING
Each tire, including the spare (if provided), should be checked at least once every two weeks
when cold and inflated to the pressure recommended by the vehicle manufacturer on the Tire
and Loading Information placard on the driver's side B-pillar or the tire pressure label on the
inside of the fuel filler flap. If your vehicle has tires of a different size than the size indicated on
the Tire and Loading Information placard or, if available, the tire pressure label, you should
determine the proper tire pressure for those tires.
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pressure indicator lamp when one or more of your tires
are significantly underinflated. Accordingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate them to the proper pressure.
Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling
and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance,
and it is the driver's responsibility to maintain correc ttire pressure, even if underinflation has
not reached the level to trigger illumination of the TPMS low tire pressure indicator lamp.
USA only:
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the system detects a malfunction, the indicator lamp will flash for 238

mostly made of anodized aluminum and
can lose their shine if chrome polish is
used. Use a damp, lint-free cloth instead
when cleaning the trim pieces.
If the chrome-plated trim pieces are very
dirty, you can use a chrome polish. If you
are unsure as to whether the trim pieces
are chrome-plated or not, consult an
authorized Mercedes-Ben zCenter.

that the leather does no tbecome
soaked. It may otherwise become rough
and cracked. Only use leather care
agents that have been tested and
approved by Mercedes-Benz. You can
obtain these from a qualified specialist
workshop.
R clean artificial leather covers with a cloth
moistened with a solution containing 1%
detergen t(e.g. dish washing liquid).
R clean cloth covers with a microfiber cloth
moistened with a solution containing 1%

Raising the vehicle G
WARNING
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate
jacking point of the vehicle. The base of the
jack must be positioned vertically, directly
under the jacking point of the vehicle.
The following must be observed when raising
the vehicle:
R to raise the vehicle, only use the vehicle-
specific jack that has been tested and
approved by Mercedes-Benz. If used
incorrectly, the jack could tip over with the
vehicle raised.
R the jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed .Itis not suited for
performing maintenance work under the
vehicle.
R avoid changing the wheel on uphill and
downhill slopes.
R before raising the vehicle, secure it from
rolling away by applying the parking brake
and inserting wheel chocks. Never
disengage the parking brake while the
vehicle is raised.
R the jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a
large, load-bearing underlay must be used.
On a slippery surface, a non-slip underlay
must be used, e.g. rubber mats.
R do not use wooden blocks or similar
objects as a jack underlay.O therwise, the
jac kw ill not be able to achieve its load-
bearing capacity due to the restricted
