If equipped, the DRL will come
on when all of the following
conditions are met:
.The ignition is on.
.The exterior lamp control is
in AUTO.
.The light sensor determines
it is daytime.
The DRL turn off when the
headlamps are turned to
Oor
the ignition is off.
For vehicles first sold in
Canada, the DRL can only be
turned off when the vehicle is
parked.
Automatic Headlamp
System
When the exterior lamp
control is set to AUTO and it is
dark enough outside, the
headlamps come on
automatically.
The light sensor is on top of
the instrument panel or on the
windshield near the rearview
mirror. Do not cover the
sensor, otherwise the
headlamps will come on when
they are not needed.
The system may also turn on
the headlamps when driving
through a parking garage or
tunnel.
If the vehicle is started in a
dark garage, the automatic
headlamp system comes on
immediately. If it is light
outside when the vehicle
leaves the garage, there is a slight delay before the
automatic headlamp system
turns off the headlamps.
During that delay, the
instrument cluster may not be
as bright as usual. Make sure
the instrument panel
brightness control is in the full
bright position. See
Instrument Panel Illumination
Control
0150.
When it is bright enough
outside, the headlamps will
turn off.
The automatic headlamp
system turns off when the
exterior lamp control is turned
to
Oor the ignition is off. For
vehicles sold in Canada, this
control only works when the
transmission is in P (Park).
Lights On with Wipers
If the windshield wipers are
activated in daylight with the
engine on, and the exterior
lamp control is in AUTO, the
headlamps, parking lamps, and
other exterior lamps come on.

240 Driving and Operating
Axle Fluid
Axles must have 2 400 km
(1,500 mi) before being used in
track driving.
The rear axle fluid
temperatures may be higher
than when driving in severe
conditions. Drain and refill with
new 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 0378.
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 0378.
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 0355.
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
