When the indicator nears empty, the low
fuel light comes on. There still is a little fuel
left, but the vehicle should be refueled soon.
The fuel gauge may:
.Take a little more, or less fuel to fill up
than it indicates. For example, the gauge
may have indicated the tank is half full,
but it actually will take a little more,
or less than half the tank's capacity to fill
the tank.
.Moves a little while turning a corner,
speeding up, or braking.
.Take a few seconds to stabilize after the
ignition is turned on and goes back to
empty when the ignition is turned off.
These are normal conditions, none of which
indicate a problem with the fuel gauge.
Hybrid Battery Charging Light
(Charge+)
If equipped, this light comes on when the
Charge+ Switch is pressed and indicates the
increase to the high voltage battery charge.
The state of charge status is displayed in
the HYBRID BATTERY info tile. See “Info
Tiles” inInstrument Cluster 081.
Hybrid Battery Charging (Charge+) will
display messages in the Driver Information
Center (DIC). See Driver Mode Control 0196.
Power Indicator Gauge
The electric power indicator gauge is in the
bottom of the display to the right of the
speedometer, and is only shown in the
Shuttle mode.
This gauge displays the instantaneous
consumption power of the high voltage
battery. Maximum power consumption is
available when the high voltage battery is
fully charged.
Engine Coolant Temperature
Gauge
This gauge shows the engine coolant
temperature.
If the gauge pointer moves into the red
zone, the engine is too hot.
This reading indicates the same thing as the
warning light. It means that the engine
coolant has overheated. If the vehicle has
been operating under normal driving
conditions, pull off the road, stop the
vehicle, and turn off the engine as soon as
possible. See Engine Overheating 0261 for
more information.

to be replaced, use GM approved brake
pads. If this is not done, the brake fade
warning system may not function properly.
Stage 1 :The Driver Information Center (DIC)
displays a “Reduce Braking to Avoid
Overheating” message, a chime sounds and
brake pedal effort and travel is increased.
When the message displays, the driver
should back up braking points and reduce
brake usage in order to reduce brake
temperature. This will allow for continued
lapping with no speed limitations.
Stage 2 : The Driver Information Center
(DIC) displays a “Brakes Overheated Service
Now” message, a chime sounds, and brake
pedal effort and travel is further increased.
This code indicates that the brake fluid
temperature is excessive and is about to
boil. The system limits vehicle speed to
100KPH/62MPH. The driver should
immediately start a cool down lap if on the
track. If this message displays, the vehicle
needs to be serviced. The brake system
needs to cool down, and the brake fluid
must be immediately flushed with DOT4 for
street use, or to a qualified DOT4 race fluid
for track use. Boiled brake fluid is
compromised and must be replaced. Brake Burnishing
Caution
Performing the brake burnish procedure
on a base brake system can result in
brake damage.
Caution
The new vehicle break-in period should be
completed before performing the brake
burnish procedure, otherwise damage
may occur to the powertrain/engine. See
New Vehicle Break-In
0177.
Caution
Brake pedal fade will occur during any
track burnish procedure and can cause
brake pedal travel and force to increase.
This could extend stopping distance until
the brakes are fully burnished.
New brake pads must be burnished before
racing or other competitive driving.
When this procedure is performed as
instructed, it will not damage the brakes.
The brake pads will smoke and produce an odor. The braking force and pedal travel
may increase. After the procedure, the brake
pads may appear white at the rotor contact.
Perform this procedure only on dry
pavement, in a safe manner, and in
compliance with all local and state
ordinances/laws regarding motor vehicle
operation.
Brake Burnishing Procedure for J55 (Stingray
with Z51) and J56 (Z06 Standard) Brakes
This brake burnish procedure should only be
performed on vehicles with the Z06 with
J56, or Z51 with J55 factory equipped brake
systems.
1. Using the friction bubble in the Cluster Performance menu, apply the brakes 25
times starting at 100 km/h (60 mph) to
50 km/h (30 mph) while decelerating at
0.4 g. See Instrument Cluster 081. This is
a medium brake application. Drive for at
least 1 km (0.6 mi) between applying the
brakes. This first step may be skipped if
there are more than 320 km (200 mi) on
the brake pads.
2. Apply the brakes 25 times starting at 100 km/h (60 mph) to 25 km/h (15 mph)
while decelerating at 0.8 g. This is a hard
brake application without activating the

172 Driving and Operating
{Warning
Using the brakes to slow the vehicle on a
long downhill slope can cause brake
overheating, can reduce brake
performance, and could result in a loss of
braking. Shift the transmission to a lower
gear to let the engine assist the brakes
on a steep downhill slope.
{Warning
Coasting downhill in N (Neutral) or with
the ignition off is dangerous. This can
cause overheating of the brakes and loss
of steering assist. Always have the engine
running and the vehicle in gear.
.Drive at speeds that keep the vehicle in
its own lane. Do not swing wide or cross
the center line.
.Be alert on top of hills; something could
be in your lane (e.g., stalled car, crash).
.Pay attention to special road signs
(e.g., falling rocks area, winding roads,
long grades, passing or no-passing zones)
and take appropriate action.
Winter Driving
Driving on Snow or IceCaution
To avoid damage to the wheels and
brake components, always clear snow and
ice from inside the wheels and
underneath the vehicle before driving.
Snow or ice between the tires and the road
creates less traction or grip, so drive
carefully. Wet ice can occur at about 0 °C
(32 °F) when freezing rain begins to fall.
Avoid driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating too quickly
causes the wheels to spin and makes the
surface under the tires slick.
.Turn on Traction Control. On E-Ray, the
electric all-wheel drive system (eAWD)
automatically engages when wheel slip is
detected. See Traction Control/Electronic
Stability Control 0194 and
All-Wheel Drive 0191.
.The Antilock Brake System (ABS) improves
vehicle stability during hard stops, but
the brakes should be applied sooner than
when on dry pavement. See Antilock
Brake System (ABS) 0192.
.Turn off cruise control.
.Turn on Weather Mode. See Driver Mode
Control 0196.
.Allow greater following distance and
watch for slippery spots. Icy patches can
occur on otherwise clear roads in shaded
areas. The surface of a curve or an
overpass can remain icy when the
surrounding roads are clear. Avoid sudden
steering maneuvers and braking while
on ice.
Cold Weather Mode
In very low temperatures, a cold weather
message may display on the Driver
Information Center (DIC). The engine speed,
transmission shift patterns, and cabin fan
speed may operate differently to enable the
vehicle to warm up quicker. You can
manually override the cabin fan speed in
cold weather mode.
