Warning
G
You must observe the legal requirements for
the country in which you are driving when
operating a cell phone in the vehicle.
If it is permitted to operate a cell phone
while the vehicle is in motion, you must only
operate it when road and traffic conditions
permit. You may otherwise be distracted
from the traffic conditions, cause an acci-
dent and injure yourself and others.
Cell phones without exterior antennas may
interfere with the vehicle electronics and
thereby jeopardize the operational safety of
the vehicle. You must therefore only use
these devices when they are connected to a
separate exterior antenna.

You can disconnect the current to all your
vehicle’s consumers using the battery
isolating switch. This will prevent uncon-
trolled battery discharge caused by quies-
cent current consumption.The battery isolating switch is to the right
of the accelerator pedal in the driver’s foot-
well.

and wait for approx. 20 seconds.
\1Move red slide2 down in the direc-
tion of the arrow and disconnect
connector1 from the ground pin.
\1Clamp connector1 under the acceler-
ator pedal so that it cannot make con-
tact with the ground pin.
The consumers of the vehicle battery
are cut off from the electrical circuit.Warning
G
If the vehicle is equipped with an auxiliary
battery in the engine compartment, it is nec-
essary to disconnect both batteries when
working on the vehicle electrical system.
Only then is the electrical system fully dis-
connected from the power supply.iOnly disconnect the vehicle electrical
system from the power supply using
the battery isolating switch if the vehi-
cle is to be parked up for a long period
or when this is absolutely necessary.
After the power supply is switched on,
you must reset the electric sliding door
(\2page 57).

CAUTION
Make sure that the key is in position0
in the ignition lock and wait at least
20 seconds before disconnecting or
connecting the battery isolating
switch. You could otherwise damage
electrical system components.

CAUTION
When you clamp the connector under
the accelerator pedal, make sure that
the connector does not become:
\4dirty
\4damaged
It may otherwise not be possible to re-
store the electrical connection when
the parts are reassembled.

Potential problems associated with un-
derinflated and overinflated tires
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Three primary areas are affected
by improper tire inflation pressure:
1. Safety
2. Economy
Improper inflation pressures can cause un-
even wear patterns to develop across the
tire tread. These abnormal wear patterns
will reduce tread life resulting in a need for
earlier tire replacement. Underinflation
also increases tire rolling resistance and
results in higher fuel consumption.
Warning
G
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adverse-
ly affect handling and fuel economy, and are
more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride com-
fort, wear unevenly, increase stopping dis-
tance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road de-
bris, potholes etc.Warning
G
Improperly inflated tires are dangerous and
can cause accidents.
Unequal tire inflation pressures can cause
steering problems. You could lose control of
your vehicle.
Unequal tire inflation pressures from one
side of the vehicle to the other can cause
the vehicle to drift to the right or left. Always
drive with each tire inflated to the recom-
mended cold tire inflation pressure.
