Maintaining Tire Pressures
If you are not towing a trailer, keep tires inflated to the
pressures shown on the Tire and Loading Information
label, even if it diers 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 topic (see Towing and Accessories on page 83).
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 o when you adjust tire pressure. After inflating
the tire to the recommended pressure, you must drive
over
15 mph (25 km/h) for more than 10 minutes to
activate the Tire Pressure Monitoring System (TPMS),
which turns o 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 182).
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 48 or Using Right Steering Wheel
Buttons on page 49). You can also choose whether you
want to display tire pressures using Bar or PSI by
touching
Controls > Display > Tire Pressure.
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, which causes 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 suciently to aect tire pressures. Parking
the vehicle in direct sunlight or in hot weather can
also aect 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.
