Simplify
Press the thumbwheel to enter the
Simplify menu. Simplify Mode allows
certain features of the instrument
cluster to be hidden. These features
include info tiles and interactive areas.
Using the thumbwheel
SorT, except
to acknowledge an alert, will exit
Simplify Mode.
The selected features will stay hidden
even after starting and restarting the
vehicle, unless Simplify Mode is

Speedometer
The speedometer shows the vehicle
speed in either kilometers per hour
(km/h) or miles per hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
Trip Odometer
The trip odometer shows how far the
vehicle has been driven since the trip
odometer was last reset.
The trip odometer is accessed and
reset through the Driver Information
Center (DIC). See Driver Information
Center (DIC) (Base Level) 0109 or
Driver Information Center (DIC)
(Uplevel) 0112.
Tachometer
The tachometer displays the engine
speed in revolutions per minute (rpm).
For vehicles with the Stop/Start
system, when the ignition is on, the
tachometer indicates the vehicle
status. When pointing to AUTO STOP
(Base Level) or the cluster displays
AUTO STOP text (Uplevel), the engine
is off but the vehicle is on and can
move. The engine could auto start at
any time. When the indicator points
to OFF, the vehicle is off.
The tachometer may vary by several
hundred rpm, during Auto Stop mode,
when the engine is shutting off and
restarting. Uplevel
The redline of the tachometer adjusts
dynamically based on engine
temperature. The redline displays a
lower indication when the vehicles
odometer value is less than
805 kilometers (500 miles).
If equipped, the shift indicators are
displayed on instrument cluster and
Head-Up Display (HUD). The shift
indicators are only operational when
the automatic transmission is in
Manual mode, or the vehicle has a
manual transmission. See
Manual
Mode (Electronic Shifter) 0249 or
Manual Mode (Mechanical Shifter)
0 248. When the vehicle engine is less
than 70°C (158°F) and the vehicle
odometer value is less than
805 kilometers (500 miles) the shift
indications are not displayed.
A strong visual indicator is displayed
as the vehicle approaches the red line.
Tour and Sport themes feature shift
rings while the Track theme features
shift lights accompanied by a
numerical tachometer display.

trip odometer can be reset by pressing
Vand selecting yes or no while this
display is active.
The Average Fuel Economy display
shows the approximate average liters
per 100 kilometers (L/100 km) or
miles per gallon (mpg). This number
is calculated based on the number of
L/100 km (mpg) recorded since the

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 0266. Engine Boost :
If equipped, displays
engine manifold pressure relative to
ambient air pressure. It will display
boost pressure generated by the
turbocharging system.
Instantaneous Fuel Economy/
Economy Trend : Displays the current
fuel economy in liters per
100 kilometers (L/100 km) or miles per
gallon (mpg). This number reflects
only the approximate fuel economy
and changes frequently as driving
conditions change. This display
cannot be reset.
When in tour mode, shows history of
the Average Fuel Economy from the
last 100 km (62 mi). Each bar
represents about 5 km (3 mi) of
driving. When driving, the bars shift
to reflect the most recent distance on
the right side.
Lateral G-Force : If equipped,
displays inertial forces being exerted
on the vehicle in the lateral
(side-to-side) direction as numerical
value and as graphical depiction.

pressures and overall temperature as
either Cold, Cool, Normal, Warm,
or Hot. Normal is typical for normal
driving while Warm is typical for
aggressive driving. Unknown displays
when tire temperature information is
unavailable.

If equipped, shows the temperature of
the transmission fluid in either
degrees Celsius (°C) or degrees
Fahrenheit (°F).
Right Zone
Trip 1 or 2/Average Speed/Average
Fuel Economy : Trip displays the
current distance traveled, in either
kilometers (km) or miles (mi), since

When the DIC displays a message to
replace the engine air filter soon,
replace the engine air filter at the
earliest convenience.
The system must be reset after the
engine air filter is changed.
If the DIC displays a message to check
the engine air filter system, see your
dealer.
How to Reset the Engine Air
Filter Life System
To reset:1. Place the vehicle in P (Park).
2. Display the Air Filter Life on the DIC. See Driver Information Center
(DIC) (Base Level) 0109 or
Driver Information Center (DIC)
(Uplevel) 0112.
3. Press
Ton the steering wheel,
or press the trip odometer reset
stem if the vehicle does not have
DIC controls, to move to the Reset/
Disable display area. Select Reset,
then press the thumbwheel or
press the reset stem for several
seconds. 4. Press the thumbwheel or the reset
stem to confirm the reset.
Engine Air Cleaner/Filter
The engine air cleaner/filter is in the
engine compartment on the passenger
side of the vehicle for the 2.0L L4 and
2.7L L4 engines, and in the center of
the engine compartment for the 3.6L
V6 engine. See Engine Compartment
Overview 0326.
When to Inspect the Engine Air
Cleaner/Filter
.For intervals on changing and
inspecting the engine air filter, see
Maintenance Schedule 0408.
.If equipped with Engine Air Filter
Life System, see Engine Air Filter Life
System 0335.
.If driving in very dusty areas, follow
the engine air filter inspecting and
changing intervals, see Maintenance
Schedule 0408.
How to Inspect/Replace the
Engine Air Cleaner/Filter
Do not start the engine or have the
engine running with the engine air
cleaner/filter housing open. Before
removing the engine air cleaner/filter,
make sure that the engine air cleaner/
filter housing and nearby components
are free of dirt and debris.
Do not clean the engine air cleaner/
filter or components with water or
compressed air.

loading, either separately or in
combination, can cause heat
buildup and possible tire failure.
Wheel Alignment and Tire
Balance
The tires and wheels were aligned and
balanced at the factory to provide the
longest tire life and best overall
performance. Adjustments to wheel
alignment and tire balancing are not
necessary on a regular basis. Consider
an alignment check if there is unusual
tire wear or the vehicle is significantly
pulling to one side or the other. Some
slight pull to the left or right,
depending on the crown of the road
and/or other road surface variations
such as troughs or ruts, is normal.
If the vehicle is vibrating when driving
on a smooth road, the tires and
wheels may need to be rebalanced.
See your dealer for proper diagnosis.
Wheel Replacement
Replace any wheel that is bent,
cracked, or badly rusted or corroded.
If wheel nuts keep coming loose, the
wheel, wheel bolts, and wheel nutsshould be replaced. If the wheel leaks
air, replace it. Some aluminum wheels
can be repaired. See your dealer if any
of these conditions exist.
Your dealer will know the kind of
wheel that is needed.
Each new wheel should have the same
load-carrying capacity, diameter,
width, offset, and be mounted the
same way as the one it replaces.
Replace wheels, wheel bolts, wheel
nuts, or Tire Pressure Monitor System
(TPMS) sensors with new GM original
equipment parts.
{Warning
Using the wrong replacement
wheels, wheel bolts, or wheel nuts
can be dangerous. It could affect
the braking and handling of the
vehicle. Tires can lose air, and
cause loss of control, causing a
crash. Always use the correct wheel,
wheel bolts, and wheel nuts for
replacement.
Caution
The wrong wheel can also cause
problems with bearing life, brake
cooling, speedometer or odometer
calibration, headlamp aim, bumper
height, vehicle ground clearance,
and tire or tire chain clearance to
the body and chassis.
Used Replacement Wheels
{Warning
Replacing a wheel with a used one
is dangerous. How it has been used
or how far it has been driven may
be unknown. It could fail suddenly
and cause a crash. When replacing
wheels, use a new GM original
equipment wheel.
