4. Tighten the bolts with the wrench handle.
5. Rotate the winch mechanism clockwise until the wheelis properly stowed under the vehicle and until the
wench makes three audible noises.
6. Reach underneath and shake tire by hand to confirm that it is secure. The tire should not move. If the tire is
still loose and/or three audible noises are not heard,
place and secure damaged wheel into the vehicle and
seek dealer assistance for the winch mechanism. This is
for temporary use only.
Vehicles Equipped With Wheel Covers
1. Mount the road tire on the axle.
2. To ease the installation process for steel wheels with wheel covers, install two wheel bolts on the wheel.
Install the wheel bolts with the threaded end of the bolt
toward the wheel. Lightly tighten the wheel bolts.

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing service.
Towing ConditionWheel OFF the Ground ALL MODELS
Flat Tow NONENOT ALLOWED
Wheel Lift Or Dolly Tow RearNOT ALLOWED
Front OK
Flatbed ALLBEST METHOD
Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equipment
manufacturer ’s instructions. Use of safety chains is man-
datory. Attach a tow bar or other towing device to main
structural members of the vehicle, not to bumpers or
associated brackets. State and local laws regarding vehicles
under tow must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode. If the ignition key is unavailable, or the vehicle’s battery is
discharged, refer to “GEAR SELECTOR OVERRIDE” in
this section for instructions on shifting the transmission out
of PARK for towing.
CAUTION!
•
Do not use sling-type equipment when towing. Ve-
hicle damage may occur.
• When securing the vehicle to a flatbed truck, do not
attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.
The manufacturer recommends towing your vehicle with
all four wheels OFF the ground using a flatbed.

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and automatic trans-
mission control systems. When these systems are operating
properly, your vehicle will provide excellent performance
and fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light (MIL).” It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Although
your vehicle will usually be drivable and not need towing,
see your authorized dealer for service as soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.
• If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to ac-
cess this information to assist with the diagnosis and
service of your vehicle and emissions system.
WARNING!
• ONLY an authorized service technician should con-
nect equipment to the OBD II connection port in
order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the OBD
II connection port, such as a driver-behavior tracking
device, it may:
• Be possible that vehicle systems, including safety
related systems, could be impaired or a loss of
vehicle control could occur that may result in an
accident involving serious injury or death.
• Access, or allow others to access, information
stored in your vehicle systems, including personal
information.
For further information, refer to “Cybersecurity” in the
“Understanding Your Instrument Panel” section.

3. After turning the ignition to the STOP, within twominutes move the right stalk upward, into the unstable
(“anti-panic”) position, for at least half of a second. The
windshield wiper then executes part of a stroke; at each
command, approximately 1/3 of a normal wiper stroke
is triggered.
NOTE: The previous operation can be repeated up to three
times. In order to move the blades to the most suitable
position.
4. Lift the blade from the windshield and proceed with the required operation.
5. Carefully lower the blade, bringing it back in contact with the windshield.
6. Bring the blade to the initial rest position, turning the ignition to MAR-ON.
NOTE: Do not operate the screen wiper with the blades
lifted from the windshield.
Adding Washer Fluid
The fluid reservoir is located in the front of the engine
compartment. Be sure to check the fluid level in the reservoir at regular intervals. Fill the reservoir with wind-
shield washer solvent (not radiator antifreeze) and operate
the system for a few seconds to flush out the residual
water.
When refilling the washer fluid reservoir, take some
washer fluid and apply it to a cloth or towel and wipe clean
the wiper blades, this will help blade performance.
To prevent freeze-up of your windshield washer system in
cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This rating
information can be found on most washer fluid containers.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around the
washer solution.
Exhaust System
The best protection against carbon monoxide entry into the
vehicle body is a properly maintained engine exhaust
system.
286 MAINTAINING YOUR VEHICLE

Brake System
In order to assure brake system performance, all brake system
components should be inspected periodically. Refer to the
“Maintenance Schedule” for the proper maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly a collision. Driving with your foot resting or riding
on the brake pedal can result in abnormally high brake
temperatures, excessive lining wear, and possible
brake damage. You would not have your full braking
capacity in an emergency.
Brake Master Cylinder
The fluid in the master cylinder should be checked when
performing under hood services or immediately if the
“Brake Warning Light” is illuminated.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the fluid
level up to the requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be expected to
fall as the brake pads wear. Brake fluid level should be
checked when pads are replaced. However, low fluid level
may be caused by a leak and a checkup may be needed.Use only manufacturer’s recommended brake fluid. Refer
to “Fluids, Lubricants, And Genuine Parts” in “Maintain-
ing Your Vehicle” for further information.
WARNING!
•
Use only manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Using the wrong type of brake fluid can severely
damage your brake system and/or impair its perfor-
mance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.
• To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a collision.
