Messages
A/C OFF ENGINE
COOLANT HOT
This message displays when the
engine coolant becomes hotter than
the normal operating temperature.
To avoid added strain on a hot
engine, the air conditioning
compressor automatically turns off.
When the coolant temperature
returns to normal, the air
conditioning compressor turns back
on. The vehicle can continue to be
driven.
If this message continues to appear,
have the system repaired by your
dealer as soon as possible to avoid
damage to the engine.

This message displays and a chime
sounds when the engine coolant
temperature is too hot. The engine
coolant temperature warning light
will also be on. Stop and allow the
vehicle to idle until it cools down.

ENGINE OVERHEATED—
TURN VEHICLE OFF
This message displays and a
continuous chime sounds if the
engine cooling system reaches
unsafe temperatures for operation.
The engine coolant temperature
warning light will flash. Stop and
turn off the vehicle as soon as it is
safe to do so to avoid severe
damage. This message clears when
the engine has cooled to a safe
operating temperature.
Engine Oil Messages
CHANGE ENGINE OIL SOON
This message displays when the
engine oil needs to be changed.
When you change the engine oil, be
sure to reset the oil life system. See
Engine Oil Life System 0261, Driver
Information Center (DIC) 0129,
Engine Oil 0259, and Maintenance
Schedule 0329.
ENGINE OIL HOT, IDLE
ENGINE
This message displays when the
engine oil temperature is too hot.
Stop and allow the vehicle to idle
until it cools down.
ENGINE OIL LOW —ADD OIL
On some vehicles, this message
displays when the engine oil level
may be too low. Check the oil level
before filling to the recommended
level. If the oil is not low and this
message remains on, take the
vehicle to your dealer for service.
See Engine Oil 0259.
OIL PRESSURE LOW —STOP
ENGINE
This message displays if low oil
pressure levels occur. Stop the
vehicle as soon as safely possible
and do not operate it until the cause
of the low oil pressure has been
corrected. Check the oil as soon as
possible and have the vehicle
serviced by your dealer.
Engine Power Messages
ENGINE POWER IS REDUCED
This message displays when the
vehicle's engine power is reduced.
Reduced engine power can affect
the vehicle's ability to accelerate.
If this message is on, but there is no
reduction in performance, proceed
to your destination. The
performance may be reduced the
next time the vehicle is driven. The
vehicle may be driven at a reduced
speed while this message is on, but
maximum acceleration and speed
may be reduced. Anytime this
message stays on, the vehicle
should be taken to your dealer for
service as soon as possible.
Fuel System Messages
FUEL LEVEL LOW
This message displays when the
vehicle is low on fuel. Refuel as
soon as possible.

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) 0129.
Battery Power Protection
The battery saver feature is
designed to protect the vehicle's
battery.
If some interior lamps are left on
and the ignition is turned off, the
battery rundown protection system
automatically turns the lamp off after
some time.
Exterior Lighting Battery
Saver
The exterior lamps turn off about
10 minutes after the ignition is
turned off, if the parking lamps or
headlamps have been manually left
on. This protects against draining the battery. To restart the 10-minute
timer, turn the exterior lamp control
to the off position and then back to
the parking lamp or headlamp
position.
To keep the lamps on for more than
10 minutes, the ignition must be in
the ACC/ACCESSORY or ON/RUN/
START position.

competitive driving. See
Recommended Fluids and
Lubricants0333.
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.
Engine Oil
2.0L (LTG) Engine
This is not available with a track
package option and is not
recommended for track use.
3.6L Twin Turbo (LF3) Engine
This requires premium fuel, and
comes standard with a 6.63 L (7 qt)
sump, integrated oil cooler, and
other powertrain and powertrain
cooling components in preparation
for track use. 3.6L (LGX) Engine
.
With Oil Cooler: Confirm the oil
level is at the upper mark that
shows the proper operating
range on the engine oil dipstick.
. Without Oil Cooler: Do not use
for track events and competitive
driving.
6.2L Supercharged (LT4) Engine
Change the engine oil to 0W-40 or
5W-40 that meets the dexos2 ™
specification. If this oil is not
available, the following oils can be
used as an alternative: Valvoline
®
SYNPOWER MST 5W-40, Mobil®1
ESP Formula M 5W-40. See
Capacities and Specifications 0338.
This requires premium fuel, and
comes standard with a 10 qt sump,
air/oil separator, integrated oil
cooler, and other powertrain and
powertrain cooling components in
preparation for track use.
Check the oil level often during track
events and competitive driving and
keep the oil level at or near the
upper mark.
Brake Fluid
For track events and competitive
driving, it is recommended that the
brake fluid be replaced with a high
performance brake fluid that has a
dry boiling point greater than 279 °C
(534 °F). After conversion to the
high performance brake fluid, follow
the brake fluid service
recommendations outlined by the
fluid manufacturer. Do not use
silicone or DOT-5 brake fluids.
Caution
Removing the splash shield can
degrade wet braking
performance, as well as introduce
brake pedal pulsation, due to
brake disc exposure to road
debris. Only remove the front
brake disc splash shield and front
tire deflector when driving in track
events.
Brake cooling can be improved if
the front brake disc splash shield
and front tire deflector are removed.
Removing the shield will require that

least 1 km (0.6 mi) between
stops. Repeat until the brake
pedal travel starts to increase.
Depending on conditions, this
should take no longer than 25
brake applications.
3. Cool down: Drive at 100 km/h (60 mph) for approximately
15 km (10 mi) without using the
brakes.
4. Apply the brakes 25 times from 100 km/h (60 mph) to 50 km/h
(30 mph) while decelerating at
0.4 g. This is a medium brake
application. Drive for at least
1 km (0.6 mi) between
applications.
Brake Cooling
On V-Series, remove front tire
deflectors if equipped, before track
driving for optimized brake cooling.
Wheel Alignment (V-Series Only)
Wheel alignment suggested specs
for track use:
. Front: -2.0 deg camber, 0.2 deg
total toe .
Rear: -1.7 deg camber, 0.2 deg
total toe
V-Series Vehicles Equipped
With the Original Equipment
Tires
Follow the requirements and
recommendations for tire inflation
pressures while driving on various
types of tracks. This helps to
achieve a well-balanced vehicle and
enhance tire traction performance.
Use good judgment to determine the
appropriate inflation pressure and
speeds for the track configuration
and environmental conditions.
Contact the tire manufacturer if
further assistance is needed.
Inflation Pressure Guidelines
Tire pressures affect vehicle
handling and tire life, and should be
adjusted for various types of track
courses. Inspect the tires prior to
every track session. Track driving
will reduce the tire tread life.
{Warning
Operating the vehicle at high
speeds can be dangerous.
Improper tire inflation pressure
can put additional strain on the
tires and can cause a sudden
failure. Make sure the tires are in
excellent condition, and use the
correct cold tire inflation pressure
for the vehicle load and track or
course.
{Warning
Track courses put high loads on
tires operating at high speed,
which can lead to tire failure if not
inflated properly.

Speedway, Indianapolis Motor
