Roadside Emergencies 133
When Inflating Your Tires
Your MV-1 also comes equipped with a tire inflation kit. This
portable unit plugs into any of the vehicle’s 12-volt power
points and can either add air to the tire or fix a leak with an
ethylene glycol tire sealant. Instructions on how to properly
inflate or seal a tire are printed on the kit components.
When putting air into your tires (such as at a gas station or in
your garage), the Tire Pressure Monitoring System may not
respond immediately to the air added to your tires.
It may take up to two minutes of driving over 20 mph (32 km/h)
for the light to turn OFF after you have filled your tires to the
recommended inflation pressure.
Using the Tire Sealant
The tire sealant that is included with your tire inflation kit
should only be used in emergency situations. You should not
drive more than 50 mph (80 km/h) if you have used sealant on
any of the tires.
Once you have used the sealant on any of the tires, the sensor
and valves of your TPMS system must be replaced, which will
not be covered under your “New Vehicle Limited Warranties”
on page 3.
CAUTION:
Before installing a new tire, all of the sealant
must be removed from the tire/wheel assembly.
REASON: Failure to remove all of the sealant can
cause the TPMS system to give false tire pressure
measurements and cause the new sensor to fail.
How Temperature Affects Your Tire Pressure
The Tire Pressure Monitoring System (TPMS) monitors tire
pressure in each pneumatic tire. While driving in a normal
manner, a typical passenger tire inflation pressure may
increase approximately 2 to 4 psi (14 to 28 kPa) from a cold
start situation. If the vehicle is stationary overnight with the
outside temperature significantly lower than the daytime tem-
perature, the tire pressure may decrease approximately 3 psi
(20.7 kPa) for a drop of 30° F (16.6° C) in ambient tempera-
ture. This lower pressure value may be detected by the TPMS
as being lower than the recommended inflation pressure and
activate the TPMS warning for low tire pressure. If the low tire
pressure warning light is ON, visually check each tire to verify
that no tire is flat. (If one or more tires are flat, repair as neces-
sary.) Check air pressure in the road tires. If any tire is under-
inflated, carefully drive the vehicle to the nearest location
where air can be added to the tires. Inflate all tires to the rec-
ommended inflation pressure.
