English
When the ignition is on, the fuel gauge
indicates about how much fuel is left in
the tank.
There is an arrow near the fuel gauge
pointing to the side of the vehicle the fuel
door is on.
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.
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 0255 for
more information.
Transmission Temperature Gauge
This gauge will display when the
transmission is experiencing abnormal
temperatures.
As the transmission begins to overheat, the
gauge fills to the right.
The Transmission Temperature Gauge
monitors all aspects of the transmission.
Elevated transmission temperatures may not
be reflected in the Transmission Fluid
Temperature cluster display gauge.
Messages will display to indicate the
severity of the overheating. As the gauge
fills up there will be a reduction in vehicle
performance. Once full, the transmission is
overheated and a message to stop safely
will display. Do not drive the vehicle until
the message clears. See Dual Clutch
Transmission 0195 for more information.

174 Driving and Operating
Engine Cooling
If reduced performance is experienced during
track events or competitive driving, turning
off the A/C will help to improve engine
performance.
Maintain a mixture of 40% DEX-COOL
coolant and 60% clean, drinkable water to
optimize engine performance.
Fuel
Unleaded gasoline, rated at 93 octane or
higher, is required.
Caution
Some high octane fuels contain additives
and compounds that may damage the
vehicle and void the vehicle warranty. See
Prohibited Fuels0227.
Dual Clutch Transmission (DCT) Fluid
The transmission fluid and external canister
filter should be changed after every 24 hours
of track use. Change the fluid and external
canister filter as soon as possible if
prompted by the transmission fluid life
monitor that remaining fluid life is low. Stingray
Add an additional 2 L (2 qt) of DCT
transmission fluid before track use. It is not
required to remove the additional 2 L (2 qt)
of DCT fluid after the track event.
Any transmission level set or change should
be performed at your dealer.
Z06
Additional transmission fluid is not required
for the Z06. The Z06 comes track ready
from the factory.
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 can
occur when a door is opened or the remote
key is present.
{Warning
To avoid personal injury and/or vehicle
damage, always disconnect the battery
before performing service work on the
hydraulic brake system. Bleeding the
brake system with the battery connected
can lead to the system diagnosing a leak
or air in the braking system. A Diagnostic
Trouble Code (DTC) may set and vehicle
speed may be limited.
Brake Fluid
Replace existing brake fluid with a qualified
high performance DOT 4 brake fluid from a
sealed container. Brake fluid with a dry
boiling point >310 °C (590 °F) is qualified.
If high performance brake fluid is used,
replace it with GM approved brake fluid
before driving on public roads. If high
performance brake fluid is in the vehicle and
the age of the brake fluid is over a month
old or unknown, replace the brake fluid
before track events and competitive driving.
Do not use silicone or DOT-5 brake fluids.
Check the fluid level before each competitive
driving event.
