Jump-starting
GWARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with skin, eyes or clothing. Do not inhale any battery gases. Do not lean over
the battery. Keep children away from batteries. Wash away battery acid immediately with
plenty of clean water and seek medical attention.
GWARNING
During charging and jump-starting, explosive gases can escape from the battery. There is a
risk of an explosion.
Particularly avoid fire, open flames, creating sparks and smoking. Ensure there is suffi-
cient ventilation while charging and jump-starting. Do not lean over a battery.
GWARNING
During the charging process, a battery produces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can ignite. There is a risk of an explosion.
RMake sure that the positive terminal of a connected battery does not come into contact with
vehicle parts.
RNever place metal objects or tools on a battery.
RIt is important that you observe the described order of the battery terminals when con-
necting and disconnecting a battery.
RWhen jump-starting, make sure that the battery poles with identical polarity are con-
nected.
RIt is particularly important to observe the described order when connecting and dis-
connecting the jumper cables.
RNever connect or disconnect the battery terminals while the engine is running.
GWARNING
A discharged battery can freeze at temperatures below freezing point. When jump-starting
the vehicle or charging the battery, gases can escape from the battery. There is a risk of an
explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
!Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
If, at low temperatures, the indicator lamps/warning lamps in the instrument cluster do not
light up, it is highly likely that the discharged battery has frozen. In this case you may neither
jump-start the vehicle nor charge the battery. The service life of a thawed-out battery may be
shorter. The starting characteristics can be impaired, particularly at low temperatures. Have
the thawed-out battery checked at a qualified specialist workshop.
168Jump-starting
>> Breakdown assistance.

Do not start the vehicle using a rapid charging device. If your vehicle's battery is discharged,
the engine can be jump-started from another vehicle or from a second battery using jumper
cables. Observe the following points:
RThe battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,
jump-start the vehicle using a second battery or a jump-starting device.
RYou may only jump-start the vehicle when the engine and exhaust system are cold.
RDo not start the engine if the battery is frozen. Let the battery thaw first.
ROnly jump-start from batteries with a 12 V voltage rating.
ROnly use jumper cables which have a sufficient cross-section and insulated terminal
clamps.
RIf the battery is fully discharged, leave the battery that is being used to jump-start con-
nected for a few minutes before attempting to start. This charges the battery slightly.
RMake sure that the two vehicles do not touch.
Make sure that:
RThe jumper cables are not damaged.
RBare parts of the terminal clamp do not come into contact with other metal parts while the
jumper cables are connected to the battery.
RThe jump leads cannot come into contact with parts which can move when the engine is
running, such as the wiper rods or the fan.

Example: tire pressure table for all tires per-
mitted for this vehicle by the factory
The tire pressure table contains the recom-
mended pressures for cold tires for various
operating conditions, i.e. differing load and
speed conditions.
Example: tire pressure table with tire dimen-
sions
If a tire size precedes a tire pressure, the
tire pressure information following is only
valid for that tire size. The load conditions
"partially laden" and "fully laden" are
defined in the table for different numbers of
occupants and amounts of luggage. The actual
number of seats may differ.
Some tire pressure tables show only the rim
diameters instead of the full tire size, e.g.
R18. The rim diameter is part of the tire size
and can be found on the tire sidewall
(
Ypage 191).
If the tire pressures have been set to the
lower values for lighter loads and/or lower
road speeds, the pressures should be reset to
the higher values:
Rif you want to drive with an increased load
and/or
Rif you want to drive at higher road speeds.
iThe tire pressures for increased loads
and/or higher road speeds, shown in the
tire pressure table, may have a negative
effect on driving comfort.
If the tire pressure is not set correctly, this
can lead to an excessive build-up of heat and
a sudden loss of pressure.
For more information, contact a qualified
specialist workshop.
Important notes on tire pressure
GWARNING
If the tire pressure drops repeatedly, the
wheel, valve or tire may be damaged. Tire
pressure that is too low may result in a tire
blow-out. There is a risk of an accident.
RCheck the tire for foreign objects.
RCheck whether the wheel is losing air or
the valve is leaking.
If you are unable to rectify the damage,
contact a qualified specialist workshop.
GWARNING
If you fit unsuitable accessories onto tire
valves, the tire valves may be overloaded
and malfunction, which can cause tire pres-
sure loss. Due to their design, retrofitted
tire pressure monitors keep the tire valve
open. This can also result in tire pressure
loss. There is a risk of an accident.
Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
your vehicle onto the tire valve.
Tire pressure181
>> Wheels and tires.

Use a suitable pressure gauge to check the
tire pressure. The outer appearance of a tire
does not permit any reliable conclusion
about the tire pressure. On vehicles equip-
ped with the electronic tire pressure moni-
tor, the tire pressure can be checked in the
on-board computer.
The tire temperature and pressure increase
when the vehicle is in motion. This is
dependent on the driving speed and the load.
Therefore, you should only correct tire pres-
sures when the tires are cold.
The tires are cold:
Rif the vehicle has been parked with the
tires out of direct sunlight for at least
three hours and
Rif the vehicle has not been driven further
than 1 mile (1.6 km)
The tire temperature changes depending on
the outside temperature, the vehicle speed
and the tire load. If the tire temperature
changes by 18 ‡(10 †), the tire pressure
changes by approximately 10 kPa (0.1 bar/
1.5 psi). Take this into account when checking
the pressure of warm tires. Only correct the
tire pressure if it is too low for the current
operating conditions. If you check the tire
pressure when the tires are warm, the result-
ing value will be higher than if the tires were
cold. This is normal. Do not reduce the tire
pressure to the value specified for cold
tires. The tire pressure would otherwise be
too low.
Observe the recommended tire pressures for
cold tires:
Ron the Tire and Loading Information plac-
ard on the B-pillar on the driver's side
Rin the tire pressure table in the fuel filler
flap (Ypage 98).
Underinflated or overinflated tires
GWARNING
Tires with pressure that is too low can
overheat and burst as a consequence. In
addition, they also suffer from excessive
and/or irregular wear, which can severely
impair the braking properties and the
driving characteristics. There is a risk of an accident.
Avoid tire pressures that are too low in all
the tires, including the spare wheel.
Underinflated tires
Underinflated tires may:
Roverheat, leading to tire defects
Radversely affect handling
Rwear excessively and/or unevenly
Rhave an adverse effect on fuel consumption
GWARNING
Tires with excessively high pressure can
burst because they are damaged more easily by road debris, potholes etc. In addition,
they also suffer from irregular wear, which
can severely impair the braking properties
and the driving characteristics. There is a
risk of an accident.
Avoid tire pressures that are too high in all
the tires, including the spare wheel.
Overinflated tires
Overinflated tires may:
Rincrease the braking distance
Radversely affect handling
Rwear excessively and/or unevenly
Rhave an adverse effect on ride comfort
Rbe more susceptible to damage
Maximum tire pressures
0043Example: maximum permissible tire
pressure
Never exceed the maximum permissible tire
inflation pressure. Always observe the rec-
ommended tire pressure for your vehicle when
adjusting the tire pressure (
Ypage 180).

iThe actual values for tires are vehicle-
specific and may deviate from the values in
the illustration.
Checking the tire pressures
Important safety notes
Observe the notes on tire pressure
(Ypage 180).
Information on air pressure for the tires on
your vehicle can be found:
Ron the vehicle's Tire and Loading Informa- tion placard on the B-pillar
Rin the tire pressure table in the fuel filler
flap (Ypage 98)
Rin the "Tire pressure" section
Checking tire pressures manually
To determine and set the correct tire pres-
sure, proceed as follows:
XRemove the valve cap of the tire that is to bechecked.
XPress the tire pressure gauge securely onto
the valve.
XRead the tire pressure and compare it with
the recommended value on the Tire and
Loading Information placard (
Ypage 180).
XIf the tire pressure is too low increase the
tire pressure to the recommended value.
XIf the tire pressure is too high, release
air. To do this, press down the metal pin in
the valve using the tip of a pen, for exam-
ple. Then check the tire pressure again
using the tire pressure checker.
XScrew the valve cap onto the valve.
XRepeat these steps for the other tires.
Tire pressure monitor
General notes
iThis function is only available in the
USA.
If a tire pressure monitor is installed, the
vehicle's wheels have sensors that monitor
the tire pressures in all four tires. The tire
pressure monitor warns you if the pressure
drops in one or more of the tires. The tire pressure monitor only functions if the cor-
responding sensors are fitted to all wheels.
Important safety notes
GWARNING
Each tire, including the spare (if provi-
ded), should be checked at least once every
two weeks when cold and inflated to the
pressure recommended by the vehicle man- ufacturer on the Tire and Loading Informa-
tion placard on the driver's door 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 indi-
cated 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 moni-
toring system (TPMS) that illuminates a low
tire pressure telltale when one or more of
your tires are significantly underinflated.
Accordingly, when the low tire pressure
telltale lights up, you should stop and
check your tires as soon as possible, and
inflate them to the proper pressure. Driv-
ing on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure.
Underinflation also reduces fuel effi-
ciency and tire tread life, and may affect
the vehicle's handling and stopping abil-
ity. Please note that the TPMS is not a sub-
stitute for proper tire maintenance, and it
is the driver's responsibility to maintain
correct tire pressure, even if underinfla-
tion has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.
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 com-
bined with the low tire pressure telltale.
When the system detects a malfunction, the
Tire pressure183

Z

warning lamp will flash for approximately
a minute and then remain continuously
illuminated. This sequence will be repea-
ted every time the vehicle is started as long
as the malfunction exists. When the mal-
function indicator is illuminated, the sys-
tem 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.
It is the driver's responsibility to set the
tire pressure to that recommended for cold
tires which is suitable for the operating sit-
uation (
Ypage 180). Note that the correct tire
pressure for the current operating situation
must first be taught-in to the tire pressure
monitor. If there is a substantial loss of
pressure, the warning threshold for the warn-
ing message is aligned to the reference val-
ues taught-in. Restart the tire pressure mon-
itor after adjusting to the cold tire pressure.
The current pressures are saved as new ref-
erence values. As a result, a warning message
will appear if the tire pressure drops sig-
nificantly.
The tire pressure monitor does not warn you of
an incorrectly set tire pressure. Observe the notes on the recommended tire pressure
(
Ypage 180).
The tire pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tire is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Avoid
abrupt steering maneuvers. The tire pressure monitor has a yellow warn-
ing lamp in the instrument cluster for indi-
cating a pressure loss or malfunction.
Whether the warning lamp flashes or lights up
indicates whether a tire pressure is too low
or the tire pressure monitor is malfunction-
ing:
RIf the warning lamp is lit continuously, the
tire pressure on one or more tires is sig-
nificantly too low. The tire pressure mon-
itor is not malfunctioning.
RIf the warning lamp flashes for around a
minute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
iA message appears in the display in addi-
tion to the warning lamp.
Observe the information on display mes-
sages (
Ypage 126).
If the tire pressure monitor is malfunction-
ing, it may take up to ten minutes for the tire
pressure warning lamp to inform you of the
malfunction. The malfunction will be indi-
cated first by the tire pressure warning lamp
flashing for approximately one minute and
then remaining lit. When the malfunction has
been rectified, the tire pressure warning
lamp goes out after a few minutes of driving.
The operation of the tire pressure monitor
can be affected by interference from radio
transmitting equipment (e.g. radio head-
phones, two-way radios) that may be being
operated in or near the vehicle.
Tire pressure monitor warning messages
If the tire pressure monitor detects a pres-
sure loss in one or more tires, a warning mes-
sage is shown in the display. The yellow warn-
ing light in the tire pressure monitor lights
up. For certain display messages a warning
tone also sounds.
RIf the Correct Tire Pressuremessage
appears in the display, the tire pressure in
at least one tire is too low. Correct the tire
pressure at the next opportunity.
RIf the Tire Pressure Warning TireFailuremessage appears in the display,
the tire pressure in one or more tires has
dropped suddenly and the tires must be
checked.
Observe the instructions and safety notes for the display messages in the "Tires" section
