Fuel Range
The uplevel instrument cluster has a
estimated fuel range located at the
bottom center of the display. The fuel
range is displayed with the
approximate distance the vehicle can
be driven without refueling. The fuel
range estimate is based on an average
of the vehicle’s fuel economy over
recent driving history and the amount
of fuel remaining in the fuel tank.
When the estimated fuel range is low,
the range shows LOW and a message
may also display in the Driver
Information Center (DIC).
Engine Coolant
Temperature Gauge (Base
Level)
Metric
English
This gauge measures the temperature
of the vehicle's engine.
While driving under normal operating
conditions, if the red LED is
illuminated, the engine is too hot. Pull
off the road, stop the vehicle, and turn
off the engine as soon as possible.

Engine Coolant
Temperature Gauge
(Uplevel)
Sport Mode Shown, Track ModeSimilar
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 0347 for more
information.
Seat Belt Reminders
Driver Seat Belt Reminder Light
There is a driver seat belt reminder
light on the instrument cluster.
When the vehicle is started, this light
flashes and a chime may come on to
remind the driver to fasten their
seat belt.
Then the light stays on solid until the
belt is buckled. This cycle may
continue several times if the driver
remains or becomes unbuckled while
the vehicle is moving.
If the driver seat belt is buckled,
neither the light nor the chime
comes on.
Front Passenger Seat Belt
Reminder Light
The vehicle may have a front
passenger seat belt reminder light
near the passenger airbag status
indicator. See Passenger Sensing
System 061.
When the vehicle is started, this light
flashes and a chime may come on to
remind passengers to fasten their
seat belt.
Then the light stays on solid until the
belt is buckled. This cycle continues
several times if the front passenger
remains or becomes unbuckled while
the vehicle is moving.
If the front passenger seat belt is
buckled, neither the chime nor the
light comes on.

Engine Boost :Displays engine
manifold pressure relative to ambient
air pressure. It will display boost
pressure generated by the
turbocharging system.

the transmission fluid in either
degrees Celsius (°C) or degrees
Fahrenheit (°F).

The DIC is displayed in the
instrument cluster. It shows the status
of many vehicle systems.
DIC information is broken down into
two main zones: Left Zone :
Displays on the
instrument cluster to the left of the
speedometer.
Right Zone : Displays on the
instrument cluster to the right of the
speedometer.

DIC Info Tiles Selection
The following is the list of all possible
DIC Info Tiles. Depending on the
vehicle, some may not be available.
Left Zone
Battery Voltage : Displays the current
battery voltage. The battery voltage
can fluctuate while viewing this
information on the DIC. This is
normal.
Coolant Temperature : Displays the
coolant temperature in either degrees
Celsius (°C) or degrees Fahrenheit (°F).
eLSD : Displays the amount of rear
differential coupling when the
Electronic Limited-Slip Differential
(eLSD) is active and functioning
during vehicle operation. A reading of
1% is an open differential and 100% is
locked. It is normal for the value to
make small or large changes due to
driving conditions and driver inputs.
For the V-Series Blackwing models,
the eLSD maintains some coupling
even if the vehicle is stationary or not
accelerating. Coupling values of 3%
and up are typical. See Limited-Slip
Differential 0267.

322 DRIVING AND OPERATING
necessary to go much farther beyond
the passed vehicle before returning to
the lane. Pass on level roadways.
Avoid passing on hills if possible.
Backing Up
Hold the bottom of the steering wheel
with one hand. To move the trailer to
the left, move that hand to the left. To
move the trailer to the right, move
that hand to the right. Always back up
slowly and, if possible, have someone
guide you.
Making TurnsCaution
Turn more slowly and make wider
arcs when towing a trailer to
prevent damage to your vehicle.
Making very sharp turns could
cause the trailer to contact the
vehicle.
Make wider turns than normal when
towing, so trailer will not go over soft
shoulders, over curbs, or strike road
signs, trees, or other objects. Always
signal turns well in advance. Do not
steer or brake suddenly.
Driving on Grades
Reduce speed and shift to a lower gear
before starting down a long or steep
downhill grade. If the transmission is
not shifted down, the brakes may
overheat and result in reduced braking
efficiency.
Vehicles can tow in D (Drive). Shift
the transmission to a lower gear if the
transmission shifts too often under
heavy loads and/or hilly conditions.
When towing at higher altitudes,
engine coolant will boil at a lower
temperature than at lower altitudes.
If the engine is turned off immediately
after towing at high altitude on steep
uphill grades, the vehicle could show
signs similar to engine overheating. To
avoid this, let the engine run,
preferably on level ground, with the
transmission in P (Park) for a few
minutes before turning the engine off.
If the overheat warning comes on, see
Engine Overheating 0347.
Parking on Hills
{Warning
To prevent serious injury or death,
always park your vehicle and trailer
on a level surface when possible.
When parking your vehicle and your
trailer on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn the
wheels into the curb if facing
downhill or into traffic if facing
uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, gradually release the brake
pedal to allow the chocks to absorb
the load of the trailer.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
.Start the engine.

344 VEHICLE CARE
{Warning
Do not touch heater or radiator
hoses, or other engine parts. They
can be very hot and can burn you.
Do not run the engine if there is a
leak; all coolant could leak out.
That could cause an engine fire and
can burn you. Fix any leak before
driving the vehicle.
Caution
Do not use anything other than a
mix of DEX-COOL coolant that
meets GM Standard GMW3420 and
clean, drinkable water. Anything
else can cause damage to the
engine cooling system and the
vehicle, which would not be covered
by the vehicle warranty.
Engine Coolant
The cooling system in the vehicle is
filled with DEX-COOL engine coolant.
SeeMaintenance Schedule 0410 and
Recommended Fluids and Lubricants
0 420. The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating, see
Engine Overheating
0347.
What to Use
{Warning
Do not touch heater or radiator
hoses, or other engine parts. They
can be very hot and can burn you.
Do not run the engine if there is a
leak; all coolant could leak out.
That could cause an engine fire and
can burn you. Fix any leak before
driving the vehicle.
Use a 50/50 mixture of clean
drinkable water and DEX-COOL
coolant. This mixture:
.Gives freezing protection down to
−37 °C (−34 °F), outside temperature.
.Gives boiling protection up to
129 °C (265 °F), engine temperature.
.Protects against rust and corrosion.
.Will not damage aluminum parts.
.Helps keep the proper engine
temperature.
Caution
Do not use anything other than a
mix of DEX-COOL coolant that
meets GM Standard GMW3420 and
clean, drinkable water. Anything
else can cause damage to the
engine cooling system and the
vehicle, which would not be covered
by the vehicle warranty.
Never dispose of engine coolant by
putting it in the trash, pouring it on
the ground, or into sewers, streams,
or bodies of water. Have the coolant
changed by an authorized service
center, familiar with legal
requirements regarding used coolant
disposal. This will help protect the
environment and your health.
Checking Coolant
The vehicle must be on a level surface
when checking the coolant level.
It is normal to see coolant moving in
the upper coolant hose return line
when the engine is running. It is also
normal to see bubbles entering the
surge tank through the small hose.
