{CAUTION:
Operating the engine with the air cleaner/lter
off can cause you or others to be burned. The
air cleaner not only cleans the air; it helps to
stop ames if the engine backres. If it is not
there and the engine backres, you could be
burned. Do not drive with it off, and be careful
working on the engine with the air cleaner/
lter off.
Automatic Transmission Fluid
When to Check and Change Automatic
Transmission Fluid
A good time to check your automatic transmission uid
level is when the engine oil is changed.
Change the uid and lter at the intervals listed in
Additional Required Services on page 6-6, and be sure
to use the transmission uid listed inRecommended
Fluids and Lubricants on page 6-12.
How to Check Automatic
Transmission Fluid
Because this operation can be a little difficult, you may
choose to have this done at the dealership service
department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading on the dipstick.
Notice:Too much or too little uid can damage
your transmission. Too much can mean that some
of the uid could come out and fall on hot engine
part or exhaust system parts, starting a re.
Too little uid could cause the transmission to
overheat. Be sure to get an accurate reading if you
check your transmission uid.
Wait at least 30 minutes before checking the
transmission uid level if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic — especially in hot weather.
While pulling a trailer.
To get the right reading, the uid should be at normal
operating temperature, which is 180°F to 200°F
(82°C to 93°C).

Resetting the TPMS Identication Codes
Each TPMS sensor has a unique identication
code. Any time you rotate your vehicle’s tires or replace
one or more of the TPMS sensors, the identication
codes will need to be matched to the new tire/wheel
position. Each tire/wheel position is matched to a
sensor, by increasing or decreasing the tire’s air
pressure. The sensors are matched to the tire/wheel
positions in the following order: LF TIRE (left front tire on
the driver’s side of the vehicle), RF TIRE (right front
tire on the passengers side of the vehicle), RR
TIRE (right rear tire on the passengers side of the
vehicle), and LR TIRE (left rear tire on the driver’s side
of the vehicle).
You will have one minute to match the rst tire/wheel
position, and ve minutes overall to match all
four tire/wheel positions. If it takes longer than
one minute, to match the rst tire and wheel, or more
than ve minutes to match all four tire and wheel
positions the matching process stops and you will
need to start over.The TPMS sensor matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the engine off.
3. Turn the headlamp switch from off to the parking
lamps setting four times within three seconds. A
double horn chirp will sound and the TPMS low tire
warning light will begin to ash. The double horn
chirp and ashing TPMS warning light indicate that
the TPMS matching process has started. The
TPMS warning light should continue ashing
throughout the matching procedure. The SERVICE
TIRE MONITOR message will be displayed on
the Driver Information Center (DIC).
4. Start with the driver’s side front tire.
5. Remove the valve cap from the valve cap stem.
Activate the TPMS sensor by increasing or
decreasing the tire’s air pressure for 10 seconds,
then stop and listen for a single horn chirp.
The single horn chirp should sound within
15 seconds, conrming that the sensor identication
code has been matched to this tire and wheel
position. If you do not hear the conrming single
horn chirp, you will need to start over with Step 1.
To let air-pressure out of a tire you can use the
pointed end of the valve cap, a pencil-style
air pressure gage or a key.

When you reinstall the full-size wheel and tire, you must
also reinstall the wheel cover with attached plastic
nuts, the plastic nut caps, or the smooth center cap.
If you are reinstalling a wheel cover with attached
plastic nuts, place it on the wheel and tighten the
nuts by hand to get them started. Then tighten
the nut caps with the wheel wrench until they are
snug. Do not overtighten the nut caps or they
may break.
If you are reinstalling plastic nut caps, tighten the
nuts by hand to get them started. Then tighten
the nut caps with the wheel wrench until they are
snug. Do not overtighten the nut caps or they
may break.
If you are reinstalling the smooth center cap, place
it on the wheel and tap it into place until it seats
ush with the wheel.
Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly equipped with a secondary latch system. It is
designed to stop the spare tire from suddenly falling
off your vehicle. For the secondary latch to work,
the spare must be installed with the valve stem pointing
down. SeeStoring a Flat or Spare Tire and Tools on
page 5-100.
{CAUTION:
Before beginning this procedure read all the
instructions. Failure to read and follow the
instructions could damage the hoist assembly
and you and others could get hurt. Read and
follow the instructions listed next.
