Jack Usage Precautions
To complete the Use and Maintenance Hand-
book to which this supplement is attached,
given below are some instructions on the
proper use of the jack.
WARNING!
When using the crank, make sure it turns
freely without the risk of scraping hands
against the ground.
Even the moving parts of the jack, the
“worm screw” and joints can cause inju-
ries: avoid contact with them. Clean it
thoroughly if dirtied with grease.
CAUTION!
The jack is a tool designed exclusively for
changing a wheel, in case of a puncture or
damage to a tire of the vehicle on which it
is fitted or on vehicles of the same model.
Any other use, e.g. to jack up other vehicle
models or different things, is strictly pro-
hibited. Never use it to carry out mainte-
nance or repairs under the vehicle or to
CAUTION!
change summer/winter wheels and vice
versa. Never go under the raised vehicle. If
any work under the vehicle is necessary,
contact an authorized dealer. Incorrect
placing of the jack can cause the vehicle to
drop: use it only in the positions indicated.
Do not use the jack for loads higher than
that specified on the label. Never start the
engine with vehicle raised. If the vehicle is
raised more than necessary, everything
can become more unstable, with the risk
of the vehicle dropping violently. Therefore
raise the vehicle only as much as neces-
sary for the wheel/spare.
Maintenance
• Make sure grime does not build up on the “worm screw.”
• Keep the “worm screw” lubricated.
• Never modify the jack.
Conditions Of Non-Use:
• Temperatures below −40°C.
• On sandy or muddy ground.
• On uneven ground. • On steep roads.
• In extreme weather conditions: thunder-
storms, typhoons, hurricanes, blizzards,
storms, etc.

Sealant Hose (6).
183

If the sealant (white fluid) does flow through the
Sealant Hose (6):
1. Continue to operate the pump until seal-ant is no longer flowing through the hose
(typically takes 30 - 70 seconds). As the
sealant flows through the Sealant Hose
(6), the Pressure Gauge (3) can read as
high as 70 psi (4.8 Bar). The Pressure
Gauge (3) will decrease quickly from ap-
proximately 70 psi (4.8 Bar) to the actual
tire pressure when the Sealant Bottle (1)
is empty.
2. The pump will start to inject air into the tire immediately after the Sealant Bottle
(1) is empty. Continue to operate the
pump and inflate the tire to the pressure
indicated on the tire pressure label on the
driver-side latch pillar (recommended
pressure). Check the tire pressure by look-
ing at the Pressure Gauge (3).
If the tire does not inflate to at least 26 psi
(1.8 Bar) pressure within 15 minutes:
• The tire is too badly damaged. Do not attempt to drive the vehicle further. Call for
assistance. NOTE:
If the tire becomes overinflated, push the
Deflation Button to reduce the tire pressure
to the recommended inflation pressure be-
fore continuing.

on the fitting at the end of the hose, and
place the Tire Service Kit in the vehicle
storage location. Quickly proceed to (D)
“Drive Vehicle.”
CAUTION!
• The metal end fitting from Power Plug(8) may get hot after use, so it should be
handled carefully.
CAUTION!
•Failure to reinstall the cap on the fitting at
the end of the Sealant Hose (6) can result
in sealant contacting your skin, clothing,
and the vehicle’s interior. It can also re-
sult in sealant contacting internal Tire
Service Kit components which may cause
permanent damage to the kit.
(D) Drive Vehicle:
Immediately after injecting sealant and in-
flating the tire, drive the vehicle 5 miles
(8 km) or ten minutes to ensure distribution
of the Tire Service Kit Sealant within the tire.
Do not exceed 55 mph (90 km/h).
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 55 mph (90 km/h) until the tire
is repaired or replaced. Failure to follow this
warning can result in injuries that are seri-
ous or fatal to you, your passengers, and
others around you.

CAUTION!
Accessories plugged into the vehicle
power outlets draw power from the vehi-
cle’s battery, even when not in use (i.e.,
cellular devices, etc.). Eventually, if
plugged in long enough without engine
operation, the vehicle’s battery will dis-
charge sufficiently to degrade battery life
and/or prevent the engine from starting.
REFUELING IN EMERGENCY
Emergency Fuel Filler Door Release
If you are unable to open the fuel filler door,
use the fuel filler door emergency release.
1. Open the liftgate.
2. Remove access door located on right inte-rior trim panel for release cable with the
tip of your key.
3. Grab the release cable tether and pull up to release the fuel filler door.
IF YOUR ENGINE
OVERHEATS
In any of the following situations, you can
reduce the potential for overheating your en-
gine by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the
transmission in NEUTRAL, but do not in-
crease engine idle speed.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads “H,” pull over and stop the
vehicle. Idle the vehicle with the air con-
ditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on the “H” and you hear continu-
ous chimes, turn the engine off immedi-
ately and call for service. NOTE:
There are steps that you can take to slow
down an impending overheat condition:
• If your Air Conditioner (A/C) is on, turn it
off. The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
• You can also turn the temperature control to maximum heat, the mode control to floor
and the blower control to high. This allows
the heater core to act as a supplement to
the radiator and aids in removing heat from
the engine cooling system.WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator or coolant
bottle is hot.
