Tire Care and Maintenance

Displaying Tire Pressures
You can display tire pressures on the instrument panel
by using the right or left steering wheel buttons to
display Car Status (see Using Left Steering Wheel
Buttons on page 50 or Using Right Steering Wheel
Buttons on page 51). You can also choose whether you
want to display tire pressures using Bar or PSI by
touching Controls > Display > Tire Pressure.
Maintaining Tire Pressures
Keep tires inflated to the pressures shown on the Tire
and Loading Information label, even if it differs from the
pressure printed on the tire itself. The Tire and Loading
Information label is located on the center door pillar and
is visible when the front door is open.
If you are towing a trailer, do not use the tire pressures
printed on the Tire and Loading Information Label.
Instead, refer to the tire pressures published in the
towing section (see Towing and Accessories on page
82).
The Tire Pressure indicator light on the
instrument panel alerts you if one or more
tires is under- or over-inflated.
The Tire Pressure indicator light does not immediately
turn off when you adjust tire pressure. After inflating the
tire to the recommended pressure, you must drive over
15 mph (25 km/h) for a short amount of time to activate
the Tire Pressure Monitoring System (TPMS), which turns
off the Tire Pressure indicator light.
If the indicator light flashes for one minute whenever
you power on Model X, a fault with the TPMS is detected
(see TPMS Malfunction on page
184
188).
NOTE: Your vehicle's tire pressures will drop in cold
ambient temperatures. If the TPMS indicator light
appears, inflate the tires before driving. The tires will
lose one PSI for every 10° F (6° C) drop in outside
temperature. Proper tire pressures help protect tires
from potholes and improve range when properly
inflated.
WARNING: 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, resulting in unexpected
loss of vehicle control and increased risk of injury.
Under-inflation also reduces the vehicle's range
and tire tread life.
WARNING: Check tire pressures using an accurate
pressure gauge when tires are cold. It takes only
about one mile (1.6 km) of driving to warm up the
tires sufficiently to affect tire pressures. Parking
the vehicle in direct sunlight or in hot weather can
also affect tire pressures. If you must check warm
tires, expect increased pressures. Do not 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.
Checking and Adjusting Tire Pressures
Follow these steps when tires are cold and Model X has
been stationary for over three hours:
1. Refer to the Tire and Loading Information label
located on the driver's center door pillar for the
target tire pressure.
2. Remove the valve cap.
3. Firmly press an accurate tire pressure gauge onto the
valve to measure pressure.
4. If required, add or remove air to reach the
recommended pressure.
NOTE: You can release air by pressing the metal stem
in the center of the valve.
5. Re-check pressure using the accurate tire gauge.
6. Repeat steps 3 and 4 as necessary until the tire
pressure is correct.
7. Reinstall the valve cap to prevent dirt from entering.
Periodically check the valve for damage and leaks.
Inspecting and Maintaining Tires
Regularly inspect the tread and side walls for any sign of
distortion (bulges), foreign objects, cuts or wear.
WARNING: Do not drive Model X if a tire is
damaged, excessively worn, or inflated to an
incorrect pressure. Check tires regularly for wear,
and ensure there are no cuts, bulges or exposure
of the ply/cord structure.
