Chevrolet 2009 Colorado, Owner'S Manual

Get the vehicle warmed up by driving about
15 miles (24 km) when outside temperatures are
above 50°F (10°C). If it is colder than 50°F (10°C),
drive the vehicle in 3 (Third) until the engine temperature
gage moves and then remains steady for 10 minutes.
A cold fluid check can be made after the vehicle has
been sitting for eight hours or more with the engine off,
but this is used only as a reference. Let the engine run
at idle for five minutes if outside temperatures are 50°F
(10°C) or more. If it is colder than 50°F (10°C), the engine
might have to idle longer. Should the fluid level be low
during this cold check, check the fluid hot before adding
fluid. Checking the fluid hot gives a more accurate
reading of the fluid level.
Checking the Fluid Level
To prepare the vehicle:
1. Park the vehicle on a level place. Keep the engine
running.
2. With the parking brake applied, place the shift lever
in P (Park).
3. With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, position
the shift lever in P (Park).
4. Let the engine run at idle for three minutes or more.
Then, without shutting off the engine:
1. Flip the handle up and then pull out the dipstick
and wipe it with a clean rag or paper towel.
The automatic transmission
dipstick handle with this
symbol on it is located in
the engine compartment
on the passenger side of
the vehicle.
See Engine Compartment Overview on page 5-12
for more information on location.
2. Push it back in all the way, wait three seconds, and
pull it back out again.
