LIGHTING 141
If the vehicle has remained parked for
an extended period of time with no
remote key use or keyless access
operation, approach detection will be
disabled. To reactivate, press any
button on the remote key or open and
close all vehicle doors to re-enable the
entry lighting feature on approach.
Exit Lighting
Some exterior lamps and interior
lamps turn on when the driver door is
opened after the ignition is turned off.
The interior lights turn on when the
ignition is turned off.
The exterior and interior lamps
remain on for a set amount of time,
then automatically turn off.
The exterior lamps turn off
immediately by turning the exterior
lamp control off.
This feature can be changed. See
Vehicle Personalization0126.
Battery Load Management
The vehicle has Electric Power
Management (EPM), which estimates
the battery's temperature and state of charge. It then adjusts the voltage for
best performance and extended life of
the battery.
When the battery's state of charge is
low, the voltage is raised slightly to
quickly bring the charge back up.
When the state of charge is high, the
voltage is lowered slightly to prevent
overcharging. If the vehicle has a
voltmeter gauge or a voltage display
on the Driver Information Center
(DIC), you may see the voltage move
up or down. This is normal. If there is
a problem, an alert will be displayed.
The battery can be discharged at idle
if the electrical loads are very high.
This is true for all vehicles. This is
because the generator (alternator)
may not be spinning fast enough at
idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog lamps,
rear window defogger, climate control
fan at high speed, heated seats, engine
cooling fans, and loads plugged into
accessory power outlets.
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
It can increase engine idle speed to
generate more power, whenever
needed. It can temporarily reduce the
power demands of some accessories.
Normally, these actions occur in steps
or levels, without being noticeable. In
rare cases at the highest levels of
corrective action, this action may be
noticeable to the driver. If so, a DIC
message might be displayed. If a
battery message is displayed, it is
recommended that the driver reduce
the electrical loads as much as
possible. See
Driver Information Center
(DIC) (Base Level) 0116 or
Driver Information Center (DIC)
(Uplevel) 0119.
Battery Power Protection
This feature helps prevent the battery
from being drained, if the interior
courtesy lamps or reading lamps are
accidentally left on. If any of these
lamps are left on, they automatically
turn off after 10 minutes, if the

fluid after the first racing or
competitive driving event, and then
after every 24 hours of racing or
competitive driving. See your dealer
for the correct fluid.
Caution
During a first time track or racing
event, high axle temperatures can
occur. Damage could be caused to
the axle and would not be covered
by the vehicle warranty. Do not
drive as long or as fast the first
time the vehicle is driven on the
track or raced.
.The axle lubricant should be
replaced with new lubricant.
.On vehicles without a differential
cooler, additional cooling capacity is
required for continuous competitive
driving. The V-Series Blackwing has
a differential cooler, so no
additional cooling capacity is
necessary.
Engine OilCaution
If the vehicle is used for track
events and competitive driving, the
engine may use more oil than it
would with normal use. Low oil
levels can damage the engine.
Check the oil level often and
maintain the proper level. See
Engine Oil 0336.
Check the oil level often during track
events and competitive driving, and
keep the oil level at or near the upper
mark. See “Checking the Engine Oil" in
Engine Oil 0336.
Fuel
Use premium unleaded gasoline with
a posted octane rating of 93 at a track
event. Unleaded gasoline with a
posted octane rating of 91 may be
used, but performance will be
degraded. See Prohibited Fuels 0317.
Automatic or Manual
Transmission Fluid
Have the transmission fluid set to the
track specific oil level prior to track
usage. Transmission fluid should be
changed after every 15 hours of track
usage. Any transmission level set or
change should be performed at the
dealer.
Brakes
Battery Disconnect
Disconnect the battery before
servicing the hydraulic brake system.
It is critical to disconnect the battery
before bleeding the system, replacing
the pads, or any other work. The
battery must be disconnected to
prevent the brake master cylinder
from pressurizing the hydraulic
system during its automated self
diagnostic tests that may occur when
a door is opened or the remote key is
present.
