Tire Pressures when Towing
When towing a trailer, tire pressures must be adjusted to
accommodate the additional load. Keep tires inflated to
the pressures shown below (these pressures override the
pressures that are provided on the Tire and Loading
information label):
Front Tires
Rear Tires
Cold Tire Inflation Pressure
245/45R19
245/45R19
45 psi (310 kPa)
255/45R20
265/45R20
275/45R20
46 psi (320 kPa)
265/35ZR22 285/35ZR22
50 psi (345 kPa)
WARNING:
Check tire pressures using an accurate
pressure gauge when tires are cold. Driving 1.5 km
warms 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.
WARNING:
Never attempt to tow a trailer when a
Model X tire is faulty or has been inflated using a
tire repair kit. A temporarily repaired tire is not
designed to sustain the towing load. Towing using
a faulty or temporarily repaired tire can result in
tire failure and loss of vehicle stability.
Before Towing a Trailer
Before towing a trailer, you must do the following:
• Inflate tires to the cold tire inflation pressure
specified in Tire Pressures when Towing.
• Set Suspension to
Standard
height (touch
Controls
>
Suspension
>
Standard
).
• Observe all regulations and legal requirements in
your state/region that apply to trailer towing. Failure
to comply with regulations can compromise your
safety.
• Adjust side mirrors to provide a clear rearward view
without a significant blind spot.
• Engage
Trailer Mode
Confirm the following:
• Model X rests horizontally with the trailer attached. If
the vehicle is tipped up at the front, and down at the
rear, check that you are not exceeding the maximum
towing capacity and tongue loads provided in
Carrying Capacity.
• All trailer hitch parts and attachments and electrical
connectors (including reverse and fog lights, if
equipped) are in good condition and are properly
connected. If any problems are apparent, do not tow
the trailer.
• Trailer lights (brake lights, turn signal lights, and
marker lights) are working properly.
• The trailer tongue is securely connected to the hitch
ball.
• All cargo is secured.
• Wheel chocks are available.
• The trailer load is evenly distributed such that the
trailer tongue weight is approximately 4% of the total
trailer weight, without exceeding the maximum
tongue weights provided in Carrying Capacity.
WARNING:
The trailer tongue weight must be
approximately 4% of the total trailer weight
without exceeding the maximum tongue weights
provided in Carrying Capacity. Loads that are
balanced over the wheels or heavier in the rear can
cause trailer sway, resulting in loss of vehicle
control.
WARNING:
Always ensure that cargo is secured in
the trailer and will not shift. Dynamic load shifts
can cause loss of vehicle control, resulting in
serious injury or death.
Trailer Mode
Trailer Mode must always be active when towing a trailer.
When you connect a trailer's electrical connection,
Model X automatically engages Trailer Mode. When you
disconnect the trailer's electrical connection, Trailer
Mode disengages. To engage or exit Trailer Mode
manually, touch
Controls
>

Trailer
Mode
on the touchscreen. One of the following
indicators display on the instrument panel:
Trailer Mode is active.
Model X detects a connection for trailer
lights but Trailer Mode is disabled. It is
likely that a carrying accessory has been
connected.
