* When inflation only is required
for a tire or other objects, the
selector must be in the Air
position.
What to do When a Tire Is
Punctured
You can repair a tire puncture within the
tire's tread area in two stages with the kit.
• In the first stage, inflate the tire with a
sealing compound and air. After you
inflate the tire, you will need to drive
the vehicle a short distance (about 4 mi
(6 km) to distribute the sealant in the
tire.
• In the second stage, check the tire
pressure and adjust, if necessary, to the
vehicle's specified tire inflation
pressure.
First Stage: Inflating the Tire with
Sealing Compound and Air WARNING:
Do not stand directly
over the kit while inflating the tire. If you
notice any unusual bulges or
deformations in the tire's sidewall during
inflation, stop and call roadside
assistance. WARNING:
If the tire does not
inflate to the recommended tire pressure
within 15 minutes, stop and call roadside
assistance. WARNING:
Do not run the engine
when operating the air compressor
unless the vehicle is outdoors or in a
well-ventilated area.
Preparation: Park the vehicle in a safe, level
and secure area, away from moving traffic.
Switch the hazard lights on. Apply the
parking brake and switch the engine off.
Inspect the flat tire for visible damage. Sealant compound contains latex. Use
appropriate precautions to avoid any
allergic reactions.
Do not remove any foreign object that has
pierced the tire. If a puncture is located in
the tire sidewall, stop and call roadside
assistance.
1. Remove the valve cap from the tire
valve.
2. Unwrap the dual purpose hose (black tube) from the back of the compressor
housing.
3. Fasten the hose to the tire valve by turning the connector clockwise.
Tighten the connection securely. 4. Plug the power cable into the 12-volt
power point located on the right side
of the floor console.
5. Remove the warning sticker found on the casing/housing and place it on the
top of the instrument panel or the
center of the dash.

Oils and Fluids
In many cases, fluid discoloration is a
normal operating characteristic and, by
itself, does not necessarily indicate a
concern or that the fluid needs to be
changed. However, a qualified expert, such
as the factory-trained technicians at your
dealership, should inspect discolored fluids
that also show signs of overheating or
foreign material contamination
immediately.
Make sure to change your vehicle
’s oils and
fluids at the specified intervals or in
conjunction with a repair.
