Tire Pressure Monitoring - Tesla S Owner's Manual

Using Tire Chains
Tesla has tested and approved Security Chain
Company (SCC) Model Z-563 chains for use on the
rear wheels. These chains must only be used if your
Model S has 245/45R19 rear tires installed. Do not
use chains on 21" tires.
When installing tire chains, follow the instructions
provided by the tire chain manufacturer. Mount them
as tightly as possible.
When using tire chains:
• Drive slowly—do not exceed 48 km/h .
• Avoid heavily loading Model S (heavy loads can
reduce the clearance between the tires and the
body).
• Remove the tire chains as soon as conditions
allow.
Note: Tire chains are prohibited in some
jurisdictions. Check local laws before installing tire
chains.
Caution: Using non-recommended tire chains,
or using tire chains on other sized tires, can
damage the suspension, body, wheels, and/or
brake lines. Damage caused by using non-
recommended tire chains is not covered by the
warranty.
Caution: Ensure that tire chains cannot touch
suspension components or brake lines. If you
hear the chains making unusual noises that
would indicate contact with Model S, stop and
investigate immediately.

Tire Pressure Monitoring

Each tire should be checked monthly when cold and
inflated to the recommended pressures that are
printed on the Tire and Loading Information label
located on the driver's door pillar (see
Understanding Tire Markings
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, 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 displays a low tire pressure telltale
(Tire Pressure Warning) on the instrument panel
when one or more of your tires is significantly under-
inflated. Accordingly, when the Tire Pressure
indicator light displays on the instrument panel
alerting low tire pressure, stop and check your tires
as soon as possible, and inflate them to the proper
pressure (see Maintaining Tire Pressures
Maintenance
on page 125). If your

92). Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle's
handling and stopping ability.
If Model S detects a fault with the Tire
Pressure Monitoring System (TPMS), this
indicator flashes for one minute
whenever you power on Model S.
Note: Installing accessories that are not approved
by Tesla can interfere with the TPMS system.
Warning: The TPMS is not a substitute for
proper tire maintenance, including manually
checking tire pressures and regularly
inspecting the condition of tires. It is the
driver's responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level for the TPMS to trigger the
Tire Pressure Warning on the instrument
panel.
Resetting the TPMS Sensors
To ensure accurate tire pressure warnings after
replacing one or more wheels, the TPMS sensors
must be reset.
Note: When changing to 21" wheels (Performance
Plus models), the TPMS may generate false tire
pressure warnings. Bring Model S to a Tesla
Service center for further adjustment.
Note: The TPMS sensors do not need to be reset
after replacing a tire or rotating wheels.
Note: Do not reset the TPMS sensors in an attempt
to clear tire pressure warnings.
To reset the tire pressure sensors:
1. Inflate all tires to their recommend pressures,
as indicated on the Tire and Loading
Information label located on the driver's door
pillar.
2. Get ready to drive for ten minutes, then, on the
Model S touchscreen, touch Controls >
Settings > Vehicle > Tire Pressure Monitor >
Reset Sensors.
3.
Follow the onscreen instructions.
Replacing a Tire Sensor
If the Tire Pressure warning indicator displays
frequently, contact Tesla to determine if a tire
sensor needs to be replaced. Tire sensors must be
replaced by a Tesla service technician who can
perform a brief setup procedure. If a non-Tesla
