Replacing the batteryThe service life of the battery is subject to normal
wear; it depends greatly on care, climatic
conditions, and driving conditions (distances,
loads).
f Only use an original Porsche battery, with the
correct part number, as a replacement. Only
this battery meets the spec ific requirements of
the vehicle.
f Please observe the disposal instructions for
batteries.
Putting vehicle into operationAfter the battery is connected or after a fully
discharged battery is charged, the PSM warning
light lights up on the instrument panel and
a message appears on the multi-function display
in the instrument panel to indicate a fault.
This fault can be corrected with a few
simple steps:
1. Start the engine. To do this, turn the igni tion key or the control
unit (on vehicles with Porsche Entry & Drive)
to ignition lock position 2, twice .
2. With the vehicle stationary, perform a few steering movements to the left and right and
then drive a short distance in a straight line
until the PSM warning light goes out and the
message is erased from the multi-function
display in the instrument panel.
3. If the warnings do not disappear, then:
Drive carefully to the nearest authorized
Porsche dealer to have the fault corrected.
4. After the warnings go out: Stop the vehicle in a suitable place.
5. Store the end position for the power windows. For information on storin
g the end positions for
the power windows:
f Please see the chapter “STORING END
POSITION OF THE DOOR WINDOWS AFTER
CONNECTING THE VEHICLE BATTERY” on
page 88.
6. Teach tires on vehicles with Tire Pressure Monitoring.
For information on teaching the Tire Pressure
Monitoring system:
f Please see the chapter “TIRE PRESSURE
MONITORING (TPM)” on page 127.
7. Store end position on vehicles with a slide/ tilt roof.
For information on storing the end position for the
slide/tilt roof:

f Check operation of bulb.
Changing Light-Emitting Diodes
and Long-Life BulbsDaytime driving lights, front side lights, front turn
signal lights, gas-discharge bulbs in Bi-Xenon
headlights, as well as additional brake lights and
interior lights have light-emitting diodes and long-
life bulbs.
The LEDs cannot be replaced individually.
Replacement of the long-life bulbs involves
a greater amount of installation work.
fHave defective LEDs and bulbs replaced in
a qualified specialist workshop.
Please contact a qualified specialist workshop.
We recommend that you have an authorized
Porsche dealer to do this work as they have
trained workshop personnel and the necessary
parts and tools.
Headlight AdjustmentfCheck tire pressure and adjust if necessary.

Adjustment
The adjustment is made with the vehicle ready to
drive and the fuel tank completely filled.
The driver's seat must be loaded by a person or a
165 lbs. (75 kg) weight and the tire pressures
must meet the prescribed values. After being
loaded, the car must be rolled a few meters so
that the suspension can settle.
For checking the headlight adjustment, the
vertical position of the cutoff of the lowbeam (see
fig.) has to be projected on a vertical screen (wall)
in distance of 24.6 ft. (7.5 m) from the front lens
of the headlamp.The correc t position of the cutoff
is 3.0 in. (7.5 cm) at 24.6 ft. or 7.5 m (0.4°)
below a horizontal line, x cm from ground to the
center of the headlamp lens. Lateral adjustment of the headlights should be
carried out at a specialist workshop with an optical
adjustment unit.
Distance
Visual aim shall be performed at not less than
24.6 ft. (7.5 m) (this value is a rounded down
conversion from the 25-f
oot distance typical of
field aim using a screen). The 24.6 ft. (7.5 m)
distance is measured from the headlamp lens to
the viewing screen.
Floor
The surface upon which the vehicle rests is flat
and approximately level.
Screen
The screen upon which headlamp beams are
projected is perpendicular to the floor and the
vehicle's longitudinal axis, flat, uniformly light in
color, unobstructed, and wide and high enough to
accommodate the vehicle beam patterns to be
aimed.
The screen should be wide enough to provide at
least 3.3 ft. (1 m) of space outboard of the
vehicle's headlamp spacing.
