tire Pressure Monitoring systeM (tPMs) - 2500 only
TPMS MESSAGES
• A Tire Pressure Monitoring Light and a “low tire” message will
display along with an audible chime if one or more of your vehicle’s
four road tires are significantly under-inflated when operating in
either TPMS mode.
• It is recommended that you check the tire pressure in the morning
when the tires are cool; inflate each tire to the recommended pressure
for your vehicle. The light will turn off after your vehicle’s tire pressures
are properly inflated and the pressure has been recognized. The
vehicle may need to be driven for up to 20 minutes above 15 mph
(25 km/h) before light will turn off.
• Temperature changes can affect tire pressures, causing the TPMS light
to turn on. Tire pressures will also increase as the vehicle is driven –
this is normal and you should not adjust for this increased pressure.
• Driving on under-inflated tires reduces your vehicle’s fuel efficiency
and tire tread life. if your spare tire is in use on the vehicle, the
TPMS light may turn on. Refer to your Owner’s Manual.
