while driving, the vehicle may have
a problem with the cooling system.
Stop and turn off the vehicle to
avoid damage to the engine.
A warning chime sounds when this
light is on.
SeeEngine Overheating 0253 for
more information.
Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the vehicle is
in ON/RUN. It provides information
about tire pressures and the TPMS.
When the Light is On Steady
This indicates that one or more of
the tires are significantly
underinflated. A message in the Driver Information
Center (DIC) may also display. See
Tire Messages
0140. Stop as soon
as possible, and inflate the tires to
the pressure value shown on the
Tire and Loading Information label.
See Tires 0271.
When the Light Flashes First and
Then Is On Steady
This indicates that there may be a
problem with the TPMS. The light
flashes for about one minute and
stays on steady until the vehicle is
in OFF. This sequence repeats each
time the vehicle is in ON/RUN. See
Tire Pressure Monitor
System 0280.Engine Oil Pressure Light
Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered

Caution (Continued)
by the vehicle warranty. Check
the oil level as soon as possible.
Add oil if required, but if the oil
level is within the operating range
and the oil pressure is still low,
have the vehicle serviced. Always
follow the maintenance schedule
for changing engine oil.
The oil pressure light should come
on briefly as the vehicle is started.
If it does not come on have the
vehicle serviced by your dealer.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem. See
your dealer.

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 last time this menu item
was reset. This number reflects only
the approximate average fuel
economy that the vehicle has right
now, and will change as driving
conditions change. The Average
Fuel Economy can be reset along
with the trip odometer by pressing
and holding
Vwhile this display is
active.
Compass and Speed : Shows the
direction the vehicle is driving and
the vehicle speed in either
kilometers per hour (km/h) or miles
per hour (mph).
Total Range : Shows the remaining
distance the vehicle can be driven
combining the electric range and
fuel range. Oil Life :
The Oil Life display shows
an estimate of the oil's remaining
useful life. If REMAINING OIL LIFE
99% is displayed, that means 99%
of the current oil life remains.
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
See Engine Oil Messages 0134.
The oil should be changed as soon
as possible. See Engine Oil0243.
In addition to the engine oil life
system monitoring the oil life,
additional maintenance is
recommended. See Maintenance
Schedule 0326.
Remember, the Oil Life display must
be reset after each oil change. It will
not reset itself. Also, be careful not
to reset the Oil Life display
accidentally at any time other than
when the oil has just been changed.
It cannot be reset accurately until
the next oil change. To reset the
engine oil life system, press and
hold
Vfor several seconds while
the Oil Life display is active. See
Engine Oil Life System 0245. Tire Pressure :
Shows the
approximate pressures of all four
tires. Tire pressure is displayed in
either kilopascal (kPa) or in pounds
per square inch (psi). If the pressure
is low, the value for that tire is
shown in amber. See Tire Pressure
Monitor System 0280 andTire
Pressure Monitor Operation 0281.
Average Speed : Shows the
average speed of the vehicle in
kilometers per hour (km/h) or miles
per hour (mph). This average is
calculated based on the various
vehicle speeds recorded since the
last reset of this value. The average
speed can be reset by pressing and
holding
Vwhile this display is
active.
Timer : This display can be used as
a timer. To start the timer, press

Control System
The heating, cooling, and ventilation
for the vehicle can be controlled
with this system.
The vehicle may require the use of
an auxiliary heat source under
certain cold conditions. This
provides additional heating and defrost capability obtained by
running the engine, even if the high
voltage battery is adequately
charged. Under these conditions,
the engine will start and use fuel.
Make sure there is fuel in the tank.
Do not allow the vehicle to remain in
extreme temperatures for long
periods without being driven or
plugged in.

Air Vents
Use the louvers on the air vents to
change the direction of the airflow,
or to open and close off the airflow.Operation Tips
.
Keep all outlets open whenever
possible for best system
performance.
. Keep the path under all seats
clear of objects to help circulate
the air inside the vehicle more
effectively.
. Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
. Do not attach any devices to the
air vent slats. This restricts
airflow and may cause damage
to the air vents.
Maintenance
Passenger Compartment
Air Filter
The filter removes dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
The filter should be replaced as part
of routine scheduled maintenance.
See Maintenance Schedule 0326.
To find out what type of filter to use,
see Maintenance Replacement
Parts 0335.

Steering
Electric Power Steering
The vehicle has electric power
steering. It does not have power
steering fluid. Regular maintenance
is not required.
If power steering assist is lost due
to a system malfunction, the vehicle
can be steered, but may require
increased effort.
See your dealer if there is a
problem.
If the steering wheel is turned until it
reaches the end of its travel and is
held against that position for an
extended period of time, power
steering assist may be reduced.
If the steering assist is used for an
extended period of time, power
assist may be reduced.
Normal use of the power steering
assist should return when the
system cools down.
See specific vehicle steering
messages underService Vehicle
Messages 0139. See your dealer if
there is a problem.
Curve Tips
. Take curves at a reasonable
speed.
. Reduce speed before entering a
curve.
. Maintain a reasonable steady
speed through the curve.
. Wait until the vehicle is out of
the curve before accelerating
gently into the straightaway.
Steering in Emergencies
.There are some situations when
steering around a problem may
be more effective than braking.
. Holding both sides of the
steering wheel allows you to turn
180 degrees without removing
a hand.
. The Antilock Brake System
(ABS) allows steering while
braking.
Off-Road Recovery
The vehicle's right wheels can drop
off the edge of a road onto the
shoulder while driving. Follow
these tips:
1. Ease off the accelerator and then, if there is nothing in the
way, steer the vehicle so that it
straddles the edge of the
pavement.
2. Turn the steering wheel about one-eighth of a turn, until the
right front tire contacts the
pavement edge.
