17OWNER SAFETY INFORMATION
MAINTAIN PROPER TIRE PRESSURESCheck tire pressures monthly when tires are cold and Model S has been parked
for over three hours. Inflate tires to the Tesla recommended inflation pressures,
printed on the Tire and Loading Information Label (see page 16). These
recommended pressures provide optimum ride and handling characteristics.
WARNINGS:Under-inflation is the most common cause of tire failures and can cause a tire
to overheat, resulting in severe tire cracking, tread separation, or “blowout”,
which causes unexpected loss of vehicle control and increased risk of injury.
Under-inflation also reduces Battery range and tire tread life.
Check tire pressures using an accurate pressure gauge when tires are
cold. It takes only one mile of driving to warm up the tires sufficiently to
affect tire pressures. Parking the vehicle in direct sunlight or in high ambient
temperatures can also affect tire pressures. If you must check warm tires,
expect increased pressures. Don’t let air out of warm tires in an attempt
to match recommended cold tire pressures. A hot tire at or below the
recommended cold tire inflation pressure is dangerously under-inflated.
To check and adjust tire pressures1. Remove the valve cap, then firmly press the tire gauge onto the valve.
2. If required, add air to reach the recommended pressure.
3. Re-check pressure by removing and re-attaching the tire gauge.
4. If you added too much air, release air by pushing on the metal stem in the
center of the valve. Re-check and adjust if necessary.
5. Screw the valve cap back on to prevent dirt from entering (periodically
inspect the valve cap for damage such as cracking).TIRE PRESSURE MONITORING SYSTEM (TPMS)Each tire should be checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.)As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate them to the proper pressure.
Driving on a significantly under-inflated tire causes the tire to overheat and can
lead to tire failure. Under-iinflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and
it is the driver’s responsibility to maintain correct tire pressures, even if under-
inflation has not reached the level to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator light
to indicate when the system is not operating properly.
The TPMS malfunction indicator light is combined with the low tire pressure
telltale. When the sytem detects a malfunction, the telltale flashes for
approximately one minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups as long as the
malfunction exists.
When the malfunction indicator light is illuminated, the system may not be
able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to function properly.
The tire pressure warning on the instrument panel alerts you
if one or more of your tires is significantly under-inflated. Stop
and check tire pressures as soon as possible, and inflate to
the recommended pressures
.
NOTE: The warning light does not turn off immediately after you adjust tire
pressures. It turns off when you drive Model S above 25 mph (40 km/h) for
more than 10 minutes with tires at the recommended pressures.
