Energy UsageDisplaying Energy Usage
Touch the Energy app on the top of the
touchscreen to display a graph showing
how much energy Model S has been
using.
The graph visually shows energy consumption
and projected range. The projected range is
based on consumption over the last tenth of a
mile.
Heavy acceleration and high speed driving
cause peaks on the graph as Model S uses more
energy. Slowing down causes dips. Points at
which more energy was gained than used
(causing surplus energy to be regenerated and
fed back to the battery) are shown in green.
To change the graph’s scale, use standard
touchscreen finger gestures to pinch or expand
the display. You can show the energy used over
the past 10, 25, or 50 km. You can also change
the graph’s scale by touching Controls >
Settings > Apps > Energy.
NOTE: You can also display this graph on the
instrument panel by using the scroll button on
the steering wheel (see page 4.3).
Driving Tips to Maximize Range
Maximizing your driving range uses the same
driving habits that you use to conserve fuel in a
gasoline-powered vehicle.
Energy consumption depends on driving habits
and environmental conditions (such as cold
weather and hilly roads). To get the maximum
mileage from a charge, you should:
•Keep in mind that driving at high speeds
(such as on a freeway) decreases range.
•Avoid frequent and rapid acceleration.
•Instead of using the brake to slow down,
move your foot off the accelerator.
Whenever M odel S is moving and your foot
is off the accelerator, regenerative braking
slows down Model S and feeds surplus
energy back to the Battery (see page 4.21).
•Keep tires at the recommended inflation
pressures (see page 7.3).
•Lighten your load by removing any
unnecessary cargo.
•Limit the use of resources such as heating
and air conditioning. Using seat heaters to
keep warm is more efficient than heating
the cabin.
The power meter on the instrument panel and
the Energy app (see page 4.19) provide
feedback on energy usage. With this feedback,
you will soon become familiar with how driving
habits and environmental conditions impact
how much energy Model S is using.

Tire Care and MaintenanceTire Care and Maintenance
7.6MODEL S OWNERS 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 page 7.3). If your
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 you of low tire pressure, stop and check your tires as soon as
possible, and inflate them to the proper
pressure (see page 7.3). 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.
TPMS Malfunction
Model S has also been equipped with a TPMS
malfunction indicator to indicate when the
system is not operating properly.
The TPMS malfunction indicator is combined
with the low tire pressure indicator light. When
the system detects a malfunction, the indicator
light flashes for approximately one minute after
Model S powers on, and then remains
continuously lit. This sequence continues upon
subsequent vehicle start-ups as long as the
malfunction exists.
When the TPMS malfunction indicator is on, the
system might not be able to detect or signal
low tire pressure as intended. TPMS
malfunctions can occur for a variety of reasons,
including installing replacement or alternate
tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check
the TPMS malfunction indicator light 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.
NOTE: If a tire has been replaced or repaired
using a different tire sealant than the one
available from Tesla, and a low tire pressure is
