PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks.
Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the
tires (including spare) for proper cold inflation
pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel, or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
EXHAUST GAS
The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
Whenever a change is noticed in the sound of the
exhaust system, when exhaust fumes can be
detected inside the vehicle, or when the
underside or rear of the vehicle is damaged, have
a competent mechanic inspect the complete
exhaust system and adjacent body areas for
broken, damaged, deteriorated, or mispositioned parts. Open seams or loose connections could
permit exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust
system each time the vehicle is raised for
lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
WARNING!

Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:

Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/
liftgate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in a
closed area, such as a garage, and never sit
in a parked vehicle with the engine running
for an extended period. If the vehicle is
stopped in an open area with the engine
running for more than a short period, adjust
the ventilation system to force fresh, outside
air into the vehicle.
Guard against carbon monoxide with proper
maintenance. Have the exhaust system
inspected every time the vehicle is raised.
Have any abnormal conditions repaired
promptly. Until repaired, drive with all side
windows fully open.
When exiting the vehicle, always make sure
the ignition is in the off position, remove the
key fob from the vehicle, and lock your
vehicle.

IN CASE OF EMERGENCY

188

14. Raise the vehicle by turning the jack screwclockwise, using the swivel wrench. Raise the
vehicle only until the tire just clears the
surface and enough clearance is obtained to
install the compact spare tire. Minimum tire
lift provides maximum stability.
15. Remove the five wheel bolts and take the wheel off.
16. Make sure the contact surfaces between compact spare tire and hub are clean so that
the fastening bolts will not come loose.
17. Fit the compact spare tire by inserting the first wheel bolt for two threads into the hole
closest to the valve.
18. Take the wheel wrench and tighten the wheel bolts.
19. Inflate the compact spare tire by removing the cap from its inflation valve and screwing
on the compressor inflation hose fitting. 20. Make sure that the switch on the compressor
is in the O (off) position, open the liftgate and
insert the plug into the power socket in the
cargo area, or on the center console and
start the engine. Place the on/off switch in
the I (on) position.
Attaching Compressor To Tire
21. Inflate the compact spare tire to a pressure of 43.5 psi (3 bar).

NOTE:
If spare tire is overinflated, be sure to lower the
psi in the tire to the recommended amount by
using the deflation button on the air compressor.
22. Operate the wheel wrench on the jack to lower the vehicle.
23. Remove the jack. 24. Use the wheel wrench to fully tighten the
bolts, passing alternately from one bolt to the
diagonally opposite one.
To obtain a more accurate reading, it is advisable
to check the pressure of the compact spare tire
on the pressure gauge with the compressor off.

NOTE:
Do not stow the deflated tire in the compact
spare tire location.
The compressor was designed for inflating the
compact spare tire. Do not use it for inflating
mattresses, rafts, etc.

NOTE:
Spare tires are intended for temporary use only.
Have the full-sized tire repaired or replaced, as
soon as possible.
WARNING!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off
the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
CAUTION!
Be sure to mount the spare tire with the valve
stem facing outward. The vehicle could be
damaged if the spare tire is mounted
incorrectly.

5. Start the compressor by placing the power switch in the I (on) position.
Air Compressor
6. Inflate the tire to a pressure of at least 32 psi (2.2 bar)

Ú
page 224. In order to
obtain a more precise reading, check the
pressure value on pressure gauge with the
compressor off.
7. If the pressure is not at least 26 psi (1.8 bar) after 15 minutes, disengage the compressor
from the valve and power outlet. Then, move
the vehicle forwards approximately five tire
turns in order to distribute the sealing fluid
inside the tire evenly, and then repeat the
inflation operation. 8. Drive the vehicle for about 5 miles (8 km),
stop, engage the electric park brake, and
recheck the tire pressure.
9. If the pressure is less than 19 psi (1.3 bar), DO NOT drive the vehicle, and see an autho -
rized dealer.
10. If a pressure value of at least 19 psi (1.3 bar) is detected, restore the correct pressure (with
engine running and electric park brake
engaged), and drive immediately with great
care to an authorized dealer.
11. Apply the adhesive label from the sealant bottle where it can be easily seen by the
driver as a reminder that the tire has been
treated with a Tire Service Kit, as well as
not to exceed the speed restriction for the
treated tire.

NOTE:
Only use original sealant cartridges, which can be
purchased at an authorized dealer.
CHECKING AND RESTORING TIRE
P
RESSURE
The compressor can also be used to check and, if
necessary, restore the tire pressure.
Proceed as follows:
1. Make sure that the power switch is in the
O (off) position.
2. Connect the hose directly to the valve on the tire to be inflated.
3. Insert the plug into the socket in the passenger compartment or in the cargo area
and start the engine.

WARNING!
Tire Service Kit is not a permanent flat tire
repair. Have the tire inspected and repaired or
replaced after using Tire Service Kit. Do not
exceed 50 mph (80 km/h) until the tire is
repaired or replaced. Failure to follow this
warning can result in injuries that are serious
or fatal to you, your passengers, and others
around you. Have the tire checked as soon as
possible at an authorized dealer.
WARNING!
Do not adhere the speed restriction sticker to
the padded area on the steering wheel.
Adhering the speed restriction sticker to the
padded area on the steering wheel is
dangerous because the air bag may not
operate (deploy) normally resulting in serious
injury. In addition, do not adhere the sticker to
areas where warning lights or the
speedometer cannot be viewed.
