Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 290
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down,
and check the level.
293

After changing the engine oil, the system must be
reset as follows:
1. Turn the ignition to RUN, with the engine off.
2. Press the information and reset buttons
on the DIC at the same time to enter the
personalization menu. SeeDIC Vehicle
Personalization on page 186.
3. Press the information button to scroll through
the available personalization menu modes
until the DIC display shows OIL-LIFE RESET.
4. Press and hold the reset button until the DIC
display shows ACKNOWLEDGED. This will
tell you the system has been reset.
5. Turn the key to LOCK.
If the CHANGE OIL SOON message comes back
on when you start your vehicle, the engine oil
life system has not reset. Repeat the reset
procedure.What to Do with Used Oil
Used engine oil contains certain elements that may
be unhealthy for your skin and could even cause
cancer. Do not let used oil stay on your skin for
very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly
dispose of clothing or rags containing used engine
oil. See the manufacturer’s warnings about the use
and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from
the lter before disposal. Never dispose of oil by
putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used
oil. If you have a problem properly disposing of
your used oil, ask your dealer, a service station,
or a local recycling center for help.

{CAUTION:
You can be burned if you spill coolant
on hot engine parts. Coolant contains
ethylene glycol, and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.
1. You can remove the ll neck pressure cap
when the intercooler system, including the
upper intercooler hose, is no longer hot.
Turn the pressure cap slowly counterclockwise
about one-quarter of a turn. If you hear a
hiss, wait for that to stop. This will allow any
remaining pressure to be vented.
2. Then keep turning the pressure cap slowly,
and remove it.3. Add the proper DEX-COOL
®coolant mixture
to the ll neck, until there is coolant visible in
the horizontal tube section of the ll neck.
4. With the ll neck pressure cap off, start the
engine and let it run for at least 30 seconds.
Watch out for the engine cooling fan. Turn the
engine off. By this time, the coolant level inside
the ll neck may be lower. If the level drops so
that coolant is no longer visible in the horizontal
tube section of the ll neck, add more of the
DEX-COOL
®coolant mixture to the ll neck
until the level is again visible in the horizontal
tube section.
5. Replace the intercooler system pressure cap.
Be sure the pressure cap is hand-tight and
fully seated.
If the coolant is not at the proper level when
the system cools down again, see your dealer.

{CAUTION:
You can be burned if you spill coolant
on hot engine parts. Coolant contains
ethylene glycol and it will burn if the
engine parts are hot enough. Do not
spill coolant on a hot engine.
1. You can remove the coolant surge tank
pressure cap when the cooling system,
including the coolant surge tank pressure
cap and upper radiator hose, is no longer hot.
Turn the pressure cap slowly counterclockwise
about two or two and one-half turns. If you
hear a hiss, wait for that to stop. This will allow
any pressure still left to be vented out the
discharge hose.2. Then keep
turning the
pressure cap
slowly, and
remove it.
315

The remote positive
terminal is located
under a red tethered
cap on the engine
compartment fuse block.
Lift the cap to access
the terminal.
The remote negative (−)
ground terminal, marked
GND (−), is located
behind the engine
coolant surge tank.SeeEngine Compartment Overview on
page 290for more information on the location
of the positive (+) and negative (−) terminals
on your vehicle.
{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.

7. Locate the vertical headlamp aiming screws,
which are under the hood near each headlamp
assembly.
The adjustment screw can be turned with
a 6 mm socket wrench.8. Turn the vertical aiming screw until the
headlamp beam is aimed to the horizontal tape
line. Turn it clockwise or counterclockwise to
raise or lower the angle of the beam.
9. Make sure that the light from the headlamp is
positioned at the bottom edge of the horizontal
tape line. The lamp on the left (A) shows
the correct headlamp aim. The lamp on the
right (B) shows the incorrect headlamp aim.
10. Repeat Steps 7 through 9 for the opposite
headlamp.
