Data stored in the vehicle
Data recording
This vehicle is capable of recording diag-
nostic information relating to vehicle oper-
ation, malfunctions, and user settings. This
may include information about the perform-
ance or status of various systems, including
but not limited to, engine, throttle, steering
or brake systems, that is stored and can be

20>> Introduction.

GWARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come
into contact with your skin, eyes or cloth-
ing and that it is not swallowed. Do not
inhale fuel vapors. Keep fuel away from
children.
If you or others come into contact with fuel,
observe the following:
RWash away fuel from skin immediately
using soap and water.
RIf fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance
without delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do not induce vom-
iting.
RImmediately change out of clothing
which has come into contact with fuel.
GWARNING
Electrostatic buildup can create sparks
and ignite fuel vapors. There is a risk of
fire and explosion.
Always touch the vehicle body before open-
ing the fuel filler flap or touching the fuel
pump nozzle. Any existing electrostatic
buildup is thereby discharged.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the igni-
tion if you accidentally refuel with the
wrong fuel. Otherwise, the fuel will enter
the fuel system. Even small amounts of the
wrong fuel could result in damage to the
fuel system and the engine. Notify a quali- fied specialist workshop and have the fuel
tank and fuel lines drained completely.
!Overfilling the fuel tank could damage
the fuel system.
!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Use a filter when refueling from a fuel
can. Otherwise, the fuel lines and/or
injection system could be blocked by par-
ticles from the fuel can.
If you overfill the fuel tank, fuel could spray
out when the fuel pump nozzle is removed.
For further information on fuel and fuel qual-
ity (
Ypage 207).

!Do not drive in the overrevving range, as
this could damage the engine.
HEnvironmental note
Avoid driving at high engine speeds. This
unnecessarily increases the fuel consump-
tion of your vehicle and harms the envi-
ronment as a result of increased emissions.
The overrevving range of the engine is shown with dashed lines in the orange marking of
rev counter 0043. The fuel supply is interrupted
to protect the engine when the overrevving
range is reached.

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.
