WARNING
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.
If the warning and indicator lamps do not light up on the instrument cluster when temperatures are low, it is probably because the discharged battery has frozen. In this case, you may neither jump-
start the vehicle nor charge the battery. The service life of a battery that has been thawed may be
reduced. The starting characteristics may be impaired, especially at low temperatures. Have the
thawed battery checked at a qualified specialist workshop.
All vehicles:
! Vehicles with a petrol engine:
avoid repeated and lengthy starting attempts. Otherwise, the
non-combusted fuel may damage the catalytic converter.
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 second battery using jump leads.
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 Vehicles with a petrol engine: jump-start the vehicle only when the engine and exhaust system
are cold.
R All vehicles except vehicles with a lithium-ion battery: do not start the engine if the battery
is frozen. Let the battery thaw first.
R Jump-starting may be performed only using batteries with a nominal voltage of 12 V.
R Use only jump leads that have a sufficient cross-section and insulated terminal clamps.
R If the battery is fully discharged, leave the battery that is being used to jump-start connected 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 jump leads are not damaged.
R Non-insulated parts of the terminal clamps do not come into contact with other metal parts while
the jump leads are connected to the battery.
R The jump leads cannot come into contact with parts that can move when the engine is running,
such as the V-belt pulley or the fan.

WARNING
If you manipulate, bridge or replace a faulty
fuse with a fuse of a higher amperage, the
electric cables could be overloaded. This may result in a fire. There is a risk of an accident
and injury.
Always replace faulty fuses with specified newfuses of the correct amperage.
Blown fuses must be replaced with fuses of the same rating, which you can recognise by the
colour and fuse rating. The fuse ratings are listed
in the fuse allocation chart.
The fuse allocation chart is on the fuse box in the boot (Y page 341). Fuses

The tyre pressure values given for low loads are
minimum values that offer you good driving
comfort characteristics.
However, you can also use the values given for
higher loads. These are permissible and will not adversely affect the running of the vehicle. Tyre pressure loss warning system
General notes While the vehicle is in motion, the tyre pressure
loss warning system monitors the set tyre pres-
sure using the rotational speed of the wheels.
This enables the system to detect significant
pressure loss in a tyre. If the rotational speed of
a wheel changes as a result of a loss of tire
pressure, a corresponding warning message will
appear in the multifunction display.
You can recognise the tyre pressure loss warn-
ing by the Run Flat Indicator active Run Flat Indicator active
Restart with OK
Restart with OK message, which appears in
the Service
Service menu of the multifunction display.
Information on the message display can be
found in the "Restarting the tyre pressure loss
warning system" section (Y page 347).
Important safety notes The tyre pressure warning system does not warn
you of an incorrectly set tyre pressure. Observe the notes on the recommended tyre pressure
(Y page 345).
The tyre pressure loss warning system does not
replace the need to regularly check the tyre
pressure. An even loss of pressure on several
tyres at the same time cannot be detected by
the tyre pressure loss warning system.
The tyre pressure loss warning system is not
able to warn you of a sudden loss of air, e.g. if the
tyre is penetrated by a foreign object. In the
event of a sudden loss of air, bring the vehicle to
a halt by braking carefully. Avoid abrupt steering manoeuvres.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted on your vehicle
R road conditions are wintry
R you are driving on a loose surface (e.g. sand or
gravel) R
you adopt a very sporty driving style (corner-
ing at high speeds or driving with high rates of
acceleration)
R you are towing a very heavy or large trailer
R you are driving with a heavy load
Restarting the tyre pressure loss warn-
ing system Restart the tyre pressure loss warning system if
you have:

X Before restarting, make sure that the tyre
pressures are set properly on all four tyres for
the respective operating conditions. The rec-
ommended tyre pressures can be found in the tyre pressure table on the fuel filler flap.
The tyre pressure loss warning system can
only give reliable warnings if you have set the
correct tyre pressure. If an incorrect tyre
pressure is set, this incorrect value will be
monitored.

After an emergency spare wheel has been fitted, the system may still display the tyre pressure of
the removed wheel for a few minutes. If this
occurs, note that the value displayed for the
position where the spare wheel is fitted is not
the same as the current tyre pressure of the
emergency spare wheel.
Warning messages of the tyre pressure monitor If the tyre pressure monitor detects a pressure
loss in one or more tyres, a warning message is
shown on the multifunction display. The yellow
tyre pressure warning lamp then lights up:
R If the Please correct tyre pressure
Please correct tyre pressure
message appears on the multifunction dis-
play, the tyre pressure in at least one tyre is
too low. The tyre pressure must be corrected when the opportunity arises.
R If the Check tyre(s)
Check tyre(s) message appears on
the multifunction display, the tyre pressure in at least one tyre has dropped significantly.
The tyres must be checked.
R If the Warning tyre defect
Warning tyre defect message
appears on the multifunction display, the tyre pressure in at least one tyre has dropped sud-
denly. The tyres must be checked.
Observe the instructions and safety notes in the
display messages in the "Tyres" section
(Y page 265).
If the position of the wheels on the vehicle is
changed, the tyre pressures may be displayed in
the wrong positions for a short time. After a few minutes of driving, this is rectified and the tyre
pressures are displayed in the correct positions.
Restarting the tyre pressure monitor When you restart the tyre pressure monitor, all
existing warning messages are deleted and the
warning lamps go out. The monitor uses the cur-
rently set tyre pressures as the reference values
for monitoring. In most cases, the tyre pressure monitor will automatically detect the new refer- ence values after you have changed the tyre
pressure. However, you can also set reference
values manually as described here. The tyre
pressure monitor then monitors the new tyre
pressure values.

!
On vehicles fitted with a tyre pressure mon-
itor, electronic components are located in the wheel.
Tyre-fitting tools should not be applied in thearea of the valve, as this could damage the
electronic components.
Only have tyres changed at a qualified spe-
cialist workshop.
Interchanging the front and rear wheels of dif-
fering dimensions can render the general oper-
ating permit invalid.
Observe the instructions and safety notes in the "Fitting a wheel" section (Y page 351).
The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear wear pat-
tern has formed on the tyres. Front tyres typi-
cally wear more on the shoulders, while rear
tyres wear more in the centre.
On vehicles that have front and rear wheels of
the same size, you can interchange the wheels
every 5,000 to 10,000 km depending on the
degree of tyre wear. Ensure the direction of
rotation is maintained.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time a wheel is
interchanged. Check the tyre pressure and, if
necessary, restart the tyre pressure loss warn-
ing system (Y page 347) or the tyre pressure
monitor (Y page 349). Direction of rotation
Tyres with a specified direction of rotation have additional benefits, e.g. if there is a risk of aqua- planing. These advantages can only be gained if
the tyres are fitted corresponding to the direc-
tion of rotation.
An arrow on the sidewall of the tyre indicates its correct direction of rotation. Storing wheels
Store wheels in a cool, dry and preferably dark
place if they are not being used. Protect the
tyres against oil, grease, petrol and diesel. Fitting a wheel
