Warning!
Work improperly carried out on electronic
components and associated software could
cause them

to cease functioning. Because the
vehicle’s electronic components are
interconnected, any modifications made may
produce an undesired effect on other
systems. Electronic malfunctions could
seriously impair the operating safety of your
vehicle.
Contact an authorized Mercedes-Benz Center
for repairs or modifications to electronic
components.
Other improper work or modifications on the
vehicle could also have a negative impact on
the operating safety of the vehicle.
Some safety systems only function while the
engine is running. You should therefore never
turn off the engine while driving. G
Warning!
Heavy blows against the vehicle underbody or
tires/wheels may cause serious damage and
impair the operating safety of your vehicle.
Such blows can be caused, for example, by
running over an obstacle, road debris or a
pothole. If you feel a sudden significant
vibration or ride disturbance, or you suspect
that damage to your vehicle as occurred:
R turn on your hazard warning flashers
R slow down carefully
R drive with

caution to an area which is a safe
distance from the road
Inspect the vehicle underbody and tires/
wheels for possible damage. If the vehicle
appears unsafe, have it towed to the nearest
authorized Mercedes-Benz Center or other
qualified maintenance or repair facility for
further inspection or repairs. 22

cluster goes out.
After a cold start, the automatic transmission
shifts at a higher engine speed. This allows
the catalytic converter to reach its operating
temperature earlier.

Introduction
For information on driving with an automatic
transmission, see “Driving and parking”
(Y page 285). G
Warning!
Make sure absolutely no objects are
obstructing the pedals’ range of movement.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure the pedals
still have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between or
under the pedals. You could then no longer
brake or accelerate. This could lead to
accidents and injury.
! Allow the engine to warm up under low
load use. Do not place full load on the
engine until the operating temperature has
been reached.
Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces. This may cause serious damage to the
engine and the drivetrain which is not
covered by the Mercedes-Benz Limited
Warranty.
i During the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more quickly
to operating temperature. Gear selector lever

Warning!
It is dangerous to shift the automatic
transmission out of park position P or neutral
position N if the engine speed is higher than
idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the
engine is idling normally and when your right
foot is firmly on the brake pedal.

G
Warning!
Never charge a battery while still installed in
the vehicle unless the accessory battery
charge unit approved by Mercedes-Benz is
being used. Gases may escape during
charging and could cause an explosion that
may result

in personal injury, paint damage or
corrosion.
An accessory battery charge unit specially
adapted for Mercedes-Benz vehicles and
tested and approved by Mercedes-Benz is
available. It permits the charging of the
battery in its installed position. Contact an
authorized Mercedes-Benz Center for
information and availability.
Charge battery in accordance with the
separate instructions for the accessory
battery charger.
Have the battery charged at an authorized
Mercedes-Benz Center. If you charge the
battery yourself, follow the operating
instructions for your charging device.
Only use a battery charge unit with a
maximum charging voltage of 14.8 V.
X Charge battery in accordance with the
instructions of the battery charger
manufacturer. Jump starting
G
Warning!
Failure to follow these directions will cause
damage to the electronic components, and
can lead to a battery explosion and severe
injury or death. Never lean over batteries while connecting or
jump starting. You might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water, and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.
Attempting
to

jump start a frozen battery can
result in it exploding, causing personal injury.
Read all instructions before proceeding.
! 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. Jump starting

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.
X Make sure the two vehicles do not touch.
X Switch off all electrical consumers.
X Engage the electronic parking brake.
X Make sure the automatic transmission is in
park position P.
X Open the hood (Y page 368). Position
