the dolly manufacturer’s instructions.
5. Remove the key fob from ignition switch.6. Install a suitable clamping device, designed for tow-
ing, to secure the front wheels in the straight position.
CAUTION!
Towing with the rear wheels on the ground will
cause severe transmission damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.

If the vehicle’s battery is discharged, refer to “Shift Lever
Override” in “What to Do in Emergencies” for instruc-
tions on shifting the automatic transmission out of the
PARK position for towing.
CAUTION!
Do not attempt to use sling type equipment when
towing. When securing the vehicle to a flat bed truck,
do not attach to front or rear suspension components.
Damage to your vehicle may result from improper
towing.
Towing Without The Ignition Key Fob
Special care must be taken when the vehicle is towed
with the ignition in the LOCK/OFF position. The only
approved method of towing without the ignition key is
with a flatbed truck. Proper towing equipment is neces-
sary to prevent damage to the vehicle.
Two-Wheel Drive Models
The manufacturer recommends towing your vehicle with
all four wheelsOFFthe ground using a flatbed.
If flatbed equipment is not available, and the transmis-
sion is operable, the vehicle may be towed (with rear
wheels on the ground) with the transmission in NEU-
TRAL. Speed must not exceed 30 mph (48 km/h) and the
distance must not exceed 15 miles (24 km).
CAUTION!
Towing faster than 30 mph (48 km/h) or farther than
15 miles (24 km) with rear wheels on the ground can
cause severe damage to the transmission. Such dam-
age is not covered by the New Vehicle Limited
Warranty.

the SELECT button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the Malfunction Indicator Light (MIL).
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not
on when the engine is running, and that the OBD II
system is ready for testing. Normally, the OBD II system will be ready. The OBD II
system may
notbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:
1. Turn the ignition switch to the ON position, but do not
crank or start the engine.
2. If you crank or start the engine, you will have to start
this test over.
3. As soon as you turn the ignition switch to the ON
position, you will see the MIL symbol come on as part of
a normal bulb check.

If a bulb needs to be replaced, visit your authorized
dealer or refer to the applicable Service Manual.BULB REPLACEMENT
High Intensity Discharge Headlamps (HID) – If
Equipped
The headlamps are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlamp switch off and the key removed. Because of
this, you should not attempt to service a headlamp bulb
yourself. If a headlamp bulb fails, take your vehicle to
an authorized dealer for service.
WARNING!
A transient high voltage occurs at the bulb sockets of
High Intensity Discharge (HID) headlamps when the
headlamp switch is turned ON. It may cause serious
electrical shock or electrocution if not serviced prop-
erly. See your authorized dealer for service.

•Always use the correct bulb size and type for
replacement. An incorrect bulb size or type may
overheat and cause damage to the lamp, the socket
or the lamp wiring.
4. Align the index tabs of the front fog lamp bulb with
the slots in the collar of the bulb opening on the back of
the front fog lamp housing.
