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 correct tire
pressure, even if underinflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
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 telltale will
flash for approximately 1 minute and thenremain continuously illuminated. This
sequence will continue upon subsequent
vehicle start-ups as long as the malfunction
exists. When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of
incompatible replacement or alternate tires
or wheels on the vehicle that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.

Attempting to jump start a frozen battery can
result in it exploding, causing personal injury.
Read all instructions before proceeding.GWarning!
HYBRID vehicles: It is imperative that you read
the HYBRID Supplemental Operating
Instructions included in your vehicle literature
portfolio. You may otherwise not receive all
necessary safety information and warning for
the operation of your vehicle.
! Do not tow-start the vehicle. You could
otherwise seriously damage the automatic
transmission which is not covered by the
Mercedes-Benz Limited Warranty.
! Jump starting should only be performed
using the jump-start terminals located in
the engine compartment.
Avoid repeated and lengthy starting
attempts.
Do not attempt to start the engine using a
battery quick-charge unit.
If the engine does not run after several
unsuccessful starting attempts, have it
checked at the nearest authorized
Mercedes-Benz Center.
Excessive unburned fuel generated by
repeated failed starting attempts may
damage the catalytic converter and may
present a fire risk.
Make sure the jumper cables do not have
loose or missing insulation.
Make sure the cable clamps do not touch
any other metal part while the other end is
still attached to a battery.
If the battery is discharged, the engine can be
started with jumper cables and the fully
charged battery of another vehicle or an
equivalent starter pack. Observe the
following:
R Access to the battery is not possible on all
vehicles. If you cannot access the battery
of the other vehicle, provide jump start
power by an external battery or starter
pack.
R Jump starting should only be performed
when the engine and catalytic converter
are cold.
R Do not jump start the engine or charge the
battery if the battery is frozen. Let the
battery thaw out first.
R Only jump start from batteries with the
same voltage rating (12 V). Jump starting
with a more powerful battery could damage
the vehicle’s electrical system. Such
damage will not be covered by the
Mercedes-Benz Limited Warranty.
R Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.
R Always make sure the jumper cables are
not on or near pulleys, fans or other parts
that move when an engine is started or
running.
R Should the battery be drained completely,
let the donating power source charge the
vehicle for several minutes before
reattempting the starting process.XMake sure the two vehicles do not touch.XSwitch off all electrical consumers.XEngage the electronic parking brake.XMake sure the automatic transmission is in
park position P.XOpen the hood ( Y page 404).Jump starting515Practical hints221_AKB; 6; 20, en-USd2ugruen,Version: 2.11.8.12009-09-24T13:28:17+02:00 - Seite 515Z
