Jump-starting
Important safety notes
G
WARNING
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 sufficient
ventilation while charging and jump-starting.
Do not lean over a battery. G
WARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with the skin, eyes or clothing.
Do not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash battery acid immediately with
water and seek medical attention. G
WARNING
Non-combusted fuel can collect in the
exhaust system and ignite. There is a risk of
fire. Avoid repeated and lengthy starting
attempts.
Do not use a rapid charging device to start
the vehicle. If your vehicle's battery is
discharged, the engine can be jump-started
from another vehicle or from a donor battery
using jumper cables. For this purpose, the
vehicle has a jump-starting connection point
in the engine compartment.
The additional battery in the engine
compartmenti s not suitable for jump-starting
operations. If your vehicle requires jump-
starting, or if you use it to jump-start another
vehicle, use the jump-starting connection
point in the engine compartment.
When jump-starting, observe the following
points:
R The battery is not accessible in all vehicles.
If the other vehicle's battery is not accessible, jump-start the vehicle using a
donor battery or a jump-starting device.
R Do not start the engine if the battery is
frozen. Let the battery thaw first.
R Jump-starting may only be performed from
batteries with a nominal voltage of 12 V.
R Only use jumper cables that have a
sufficient cross-section and insulated
terminal clamps.
R If the battery is fully discharged, attach the
battery of another vehicle for a few minutes
before attempting to start. This charges the
empty battery a little.
R Make sure that the two vehicles do not
touch.
Make sure that:
R the jumper cables are not damaged.
R bare parts of the terminal clamps do not
come into contact with other metal parts
while the jumper cables are connected to
the battery.
R the jumper cables cannot come into
contact with parts such as the V-belt pulley
or the fan. These parts move when the
engine is started and while it is running.
i Jumper cables and further information
regarding jump starting can be obtained at
any qualified specialist workshop. Before connecting the jumper cables
On vehicles with a battery main switch, check
whether the battery main switch is switched
on (Y page 132).

Avoid tire pressures that are too low in all the
tires, including the spare wheel.
Underinflated tires can:
R fail from being overheated
R adversely affect handling
R wear excessively and/or unevenly
R have an adverse effect on fuel consumption
Overinflated tires G
WARNING
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 can:
R increase the braking distance
R adversely affect handling
R wear excessively and/or unevenly
R adversely affect ride comfort
R be more susceptible to damage

WARNING
Tire valve that are not approved for your
vehicle by the distributor named on the inside
cover page may result in a loss of tire
pressure. This may affect road safety. There
is a risk of an accident.
Only use tire valve that are approved for your
vehicle by the distributor named on the inside
cover page. Always make sure you have the
correct tire valve type for the tires on your
vehicle.
! Do not screw additional weights (check
valves, etc.) onto the tire valves. The
electronic components could thus be
damaged.
Only for vehicles without atire pressure

Important safety notes G
WARNING
Each tire, including the spare (if provided),
should be checked at least once a month
when cold and inflated to the pressure
recommended by the vehicle manufacturer
on the Tire and Loading Information 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 indicated on the Tire and Loading
Information placard or 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 telltale 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 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 if 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 warning lamp will
flash for approximately a minute and then
remain continuously illuminated. This
sequence will be repeated every time the
vehicle is started 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.
Vehicles with a tire pressure monitor are
equipped with sensors in the wheels that
monitor the tire pressure of all four tires. The
tire pressure monitor monitors the pressure
in all four tires; you set this pressure when
you activate the tire pressure monitor. The
tire pressure monitor warns you when the
pressure drops in one or more of the tires. The
tire pressure monitor only functions if the
corresponding sensors are installed to all
wheels.
You should always adjust the tire pressure
according to the vehicle load. Restart the tire
pressure monitor if you change the tire
pressure. Tire pressure

mshowing tire rotation for single and dual
tires
Single tires: if the tires are of identical
dimensions, you can rotate both wheels on
both the front and rear axles so that the tires'
original direction of rotation is maintained. On
unidirectional tires, an arrow on the sidewall
shows the prescribed direction of rotation of
the tire.
Twin rear tires: if the tires are of identical
dimensions, you can rotate the wheels on the
front axle and the inner wheels on the rear
axle in pairs such that the original direction of
tire rotation is retained. With unidirectional
tires, you may rotate the outside wheels at
the rear axle from one side to the other. Direction of rotation
Tires with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of hydroplaning. You will only gain these
benefits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tire indicates
its correct direction of rotation.
You may mount a spare wheel against the
direction of rotation. Observe the time
