Tire Chains
{CAUTION:
Do not use tire chains. There is not enough
clearance. Tire chains used on a vehicle without
the proper amount of clearance can cause
damage to the brakes, suspension, or other
vehicle parts. The area damaged by the tire
chains could cause you to lose control of the
vehicle and you or others may be injured in a
crash. Use another type of traction device only if
its manufacturer recommends it for use on the
vehicle and tire size combination and road
conditions. Follow that manufacturer’s instructions.
To help avoid damage to the vehicle, drive slowly,
re-adjust or remove the device if it is contacting
the vehicle, and do not spin the wheels. If you do
find traction devices that will fit, install them on the
rear tires.
If a Tire Goes Flat
Your vehicle has a tire inflator kit. There is no spare tire,
no tire changing equipment, and no place to store a tire.
It is unusual for a tire to blow out while you are driving,
especially if you maintain your tires properly. If air
goes out of a tire, it is much more likely to leak out
slowly. But, if you should ever have a blow out, here are
a few tips about what to expect and what to do:
If a front tire fails, the flat tire creates a drag that pulls
the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.

Using the Tire Sealant and Compressor
Kit to Temporarily Seal and Inate a
Punctured Tire
Follow the directions closely for correct sealant usage.
When using the tire sealant and compressor kit during
cold temperatures, warm the kit in a heated environment
for 5 minutes. This will help to inflate the tire faster.Always do a safety check first. SeeIf a Tire Goes Flat
on page 5-30
1. Remove the tire sealant and compressor kit from its
storage location. SeeTire Sealant and Compressor
Kit Storage on page 5-50
Make sure the on/off button (D) is in the off (O)
position.
2. Unwrap the sealant/air hose (F) and the power
plug (C).
3. Place the kit on the ground.
Make sure the tire valve stem is positioned close to
the ground so the hose will reach it.
4. Remove the valve stem cap from the flat tire by
turning it counterclockwise.
5. Attach the sealant/air hose (F) onto the tire valve
stem. Turn it clockwise until it is tight.

Always do a safety check first. SeeIf a Tire Goes Flat
on page 5-30
1. Remove the tire sealant and compressor kit from its
storage location. SeeTire Sealant and Compressor
Kit Storage on page 5-50
2. Unlock the air only hose (F) from the sealant
canister (B) by pulling up on the lever.
3. Pull the air only hose (F) from the sealant
canister (B).
4. Remove the power plug (C) from the air
compressor (A).
5. Place the kit on the ground.
Make sure the tire valve stem is positioned close to
the ground so the hose will reach it.
6. Remove the tire valve stem cap by turning it
counterclockwise.
7. Attach the air only hose (F) onto the tire valve stem
and press the lever down to secure it.
8. Plug the power plug (C) into the accessory power
outlet in the vehicle. Unplug all items from other
accessory power outlets. See “Accessory Power
Outlet(s) in the owner manual.”If the vehicle has an accessory power outlet, do not
use the cigarette lighter.
If the vehicle only has a cigarette lighter, use the
cigarette lighter.
Do not pinch the power plug cord in the door or
window.
9. Start the vehicle. The vehicle must be running
while using the air compressor.
10. Press the on/off (D) button to turn the
compressor on.
The compressor will inflate the tire with air only.
11. Inflate the tire to the recommended inflation pressure
using the pressure gage (E). The recommended
inflation pressure can be found on the Tire and
Loading Information label. SeeInflation - Tire
Pressure on page 5-24.
The pressure gage (E) may read higher than the
actual tire pressure while the compressor is on.
Turn the compressor off to get an accurate reading.
The compressor may be turned on/off until the
correct pressure is reached.

for 5 minutes. This will help to inflate the tire faster.Always do a safety check first. SeeIf a Tire Goes Flat
on page 5-30. Do not remove any objects that have
penetrated the tire.
1. Remove the tire sealant and compressor kit from its
storage location. SeeTire Sealant and Compressor
Kit Storage on page 5-50.
2. Unwrap the sealant/air hose (F) and the power
plug (H).
3. Place the kit on the ground.
4. Remove the valve stem cap from the flat tire by
turning it counterclockwise.
5. Attach the sealant/air hose (F) onto the tire valve
stem. Turn it clockwise until it is tight.
6. Plug the power plug (H) into the accessory power

If the vehicle has an accessory power outlet, do not
use the cigarette lighter.
If the vehicle only has a cigarette lighter, use the
cigarette lighter.
Do not pinch the power plug cord in the door or
window.

Using the Tire Sealant and Compressor
Kit without Sealant to Inate a Tire
(Not Punctured)
To use the air compressor to inflate a tire with air only
and not sealant:Always do a safety check first. SeeIf a Tire Goes Flat
on page 5-30.
1. Remove the tire sealant and compressor kit from its
storage location. SeeTire Sealant and Compressor
Kit Storage on page 5-50.
2. Unwrap the air only hose (G) and the power
plug (H).
3. Place the kit on the ground.
4. Remove the tire valve stem cap from the flat tire by
turning it counterclockwise.
5. Attach the air only hose (G) onto the tire valve stem
by turning it clockwise until it is tight.
6. Plug the power plug (H) into the accessory power
outlet in the vehicle. Unplug all items from other
