Sealing A Tire With Tire Service Kit
(A) Whenever You Stop To Use Tire Service Kit:
1. Pull over to a safe location and turn on the vehicle’sHazard Warning flashers.
2. Verify that the valve stem (on the wheel with the deflated tire) is in a position that is near to the ground.
This will allow the Tire Service Kit Hoses (6) and (7) to
reach the valve stem and keep the Tire Service Kit flat on
the ground. This will provide the best positioning of the
kit when injecting the sealant into the deflated tire and
running the air pump. Move the vehicle as necessary to
place the valve stem in this position before proceeding.
3. Place the transmission in PARK (auto transmission) or in Gear (manual transmission) and place the ignition in the
OFF position.
4. Set the parking brake.
(B) Setting Up To Use Tire Service Kit:
1. Push in the Mode Select Knob (5) and turn to the Sealant Mode position.
2. Uncoil the Sealant Hose (6) and then remove the cap from the fitting at the end of the hose.
3. Place the Tire Service Kit flat on the ground next to the deflated tire.
4. Remove the cap from the valve stem and then screw the fitting at the end of the Sealant Hose (6) onto the valve
stem.
5. Uncoil the Power Plug (8) and insert the plug into the vehicle’s 12 Volt power outlet.
NOTE: Do not remove foreign objects (e.g., screws or
nails) from the tire.

IN CASE OF EMERGENCY 433

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.
NOTE:
•You must ensure that the Auto Park Brake feature is
disabled before towing this vehicle, to avoid inadvertent
Electric Park Brake engagement. The Auto Park Brake
feature is enabled or disabled via the customer program-
mable features in the Uconnect Settings.
• Vehicles with a discharged battery or total electrical
failure when the electric parking brake (EPB) is engaged,
will need a wheel dolly or jack to raise the rear wheels
off the ground when moving the vehicle onto a flatbed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode, not the ACC mode. Note that the Safehold feature
will engage the Electric Park Brake whenever the driver’s
door is opened (if the ignition is ON, transmission is not in PARK, and brake pedal is released). If you are towing this
vehicle with the ignition in the ON/RUN mode, you must
manually disable the Electric Park Brake each time the
driver’s door is opened, by pressing the brake pedal and
then releasing the EPB.
If the key fob 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 so
that the vehicle can be moved.
CAUTION!
•
Do not use sling type equipment when towing.
Vehicle damage may occur.
• When securing the vehicle to a flat bed truck, do not
attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.
• Ensure that the Electric Park Brake is released, and
remains released, while being towed.
440 IN CASE OF EMERGENCY

Accessory Drive Belt Inspection
WARNING!
•Do not attempt to inspect an accessory drive belt
with vehicle running.
• When working near the radiator cooling fan, discon-
nect the fan motor lead. The fan is temperature
controlled and can start at any time regardless of
ignition mode. You could be injured by the moving
fan blades.
• You can be badly injured working on or around a
motor vehicle. Only do service work for which you
have the knowledge and the proper equipment. If
you have any doubt about your ability to perform a
service job, take your vehicle to a competent me-
chanic.
When inspecting accessory drive belts, small cracks that
run across ribbed surface of belt from rib to rib, are
considered normal. These are not a reason to replace belt.
However, cracks running along a rib (not across) are not
normal. Any belt with cracks running along a rib must be
replaced. Also have the belt replaced if it has excessive
wear, frayed cords or severe glazing. Conditions that would require replacement:
•
Rib chunking (one or more ribs has separated from belt
body)
• Rib or belt wear
• Longitudinal belt cracking (cracks between two ribs)
• Belt slips
• “Groove jumping (belt does not maintain correct posi-
tion on pulley)

SERVICING AND MAINTENANCE 463

CAUTION!
•The catalytic converter requires the use of unleaded
fuel only. Leaded gasoline will destroy the effective-
ness of the catalyst as an emissions control device
and may seriously reduce engine performance and
cause serious damage to the engine.
• Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to assure proper catalyst
operation and prevent possible catalyst damage. NOTE:
Intentional tampering with emissions control sys-
tems can result in civil penalties being assessed against
you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter damage:
• Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
• Do not try to start the engine by pushing or towing the
vehicle.
• Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.
