2008 CHEVROLET HHR light

Here are four things that some owners ask about. None
of these show a problem with your fuel gage:
At the service station, the gas pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank’s capacity to
ll the tank.
The gage moves a little when you turn a corner or
speed up.
The gage doesn’t go back to empty when you turn
off the ignition.
For your fuel tank capacity, seeCapacities and
Specifications on page 5-125.
Boost Gage
If equipped, this gage indicates vacuum during light to
moderate throttle and boost under heavier throttle.
This gage displays the air pressure level in the intake
manifold before it enters the engine’s combustion
chamber.
This gage is automatically centered at zero every time
the engine is started. Actual vacuum or boost is
displayed from this zero point. Changes in ambient
pressure, such as driving in mountains and changing
weather, will slightly change the zero reading.United States

OIL LIFE
Press the information button until OIL LIFE displays.
The engine oil life system shows an estimate of the oil’s
remaining useful life. It shows 100% when the system
is reset after an oil change. It alerts you to change the oil
on a schedule consistent with your driving conditions.
In addition to the engine oil life system monitoring the oil
life, additional maintenance is recommended in the
Maintenance Schedule in this manual. SeeEngine Oil
on page 5-15andScheduled Maintenance on page 6-4.
Always reset the engine oil life system after an oil
change. See “How to Reset the Engine Oil Life System”
underEngine Oil Life System on page 5-19.
COOLANT

for the front tires. Press the information button again
until LR ## PSI (kPa) ## RR displays for the rear tires.If a low tire pressure condition is detected by the system
while driving, a message advising you to check the tire
pressure appears in the display. SeeInflation - Tire
