Vehicle Hold
When Model X is stopped, Vehicle Hold can
continue to apply the brakes even after you
remove your foot from the brake pedal. When
driving on a hill or on a

Towing Capacity
The total trailer weight (including all cargo and additional equipment), and the trailer tongue
weight, must never exceed the following:TiresMaximum Towing Capacity*Maximum Tongue Weight**19"***, 20" or 22"2250 kg90 kg
*Tesla recommends a separate braking system on trailers with a loaded weight of over 450 kg. Thebraking system must be appropriate for the weight of the trailer. Follow the instructions providedby the trailer brake manufacturer to ensure that trailer brakes are properly installed, adjusted, and
maintained.
**The tongue weight is the downward force that the weight of the trailer exerts on the hitch. It must not be less than 4% of the trailer load. Carrying a significant amount of equipment,
passengers, or cargo in the tow vehicle can reduce the tongue weight it can handle, which also
reduces the maximum towing capacity. Maximum towing capacity is calculated assuming the
GVWR (Gross Vehicle Weight Rating) is not exceeded. The GVWR is printed on the Statutory
Plate (see Statutory Plate on page 189).
***A Model X with 19" winter tires supports towing ONLY if equipped with these specific tires:

you are actively navigating to a
destination and not following the route.Warning: Traffic-Aware Cruise Control
cannot detect all objects and, especially
in situations when you are driving over 80 km/h, may not brake/decelerate when
a vehicle or object is only partially in the
driving lane or when a vehicle you are
following moves out of your driving path and a stationary or slow-moving vehicle
or object is in front of you. Always pay
attention to the road ahead and stay
prepared to take immediate corrective
action. Depending on Traffic-Aware
Cruise Control to avoid a collision can
result in serious injury or death. In
addition, Traffic-Aware Cruise Control
may react to vehicles or objects that
either do not exist or are not in the lane of travel, causing Model X to slow down
unnecessarily or inappropriately.Warning: Traffic-Aware Cruise Control
may be unable to provide adequate
speed control because of limited braking capability and hills. It can also misjudgethe distance from a vehicle ahead. Driving
downhill can increase driving speed, causing Model X to exceed your set
speed (and potentially the road

Warning: Forward Collision Warning is
designed only to provide visual and
audible alerts. It does not attempt to
apply the brakes or decelerate Model X.
When seeing and/or hearing a warning, it
is the driver

Obstacle-Aware AccelerationObstacle-Aware Acceleration is designed toreduce the impact of a collision by reducing
motor torque and in some cases applying the
brakes, if Model X detects an object in its driving path. For example, Model X, while
parked in front of a closed garage door with
the Drive gear engaged, detects that you have
pressed hard on the accelerator pedal.
Although Model X still accelerates and hits the
garage door, the reduced torque may result in
less damage.
Obstacle-Aware Acceleration is designed to
operate only when all of these conditions are
simultaneously met:

Safety &
SecurityYou can manually apply and release the PARKING BRAKE see Parking Brake
on page 73), POWER OFF the vehicle (see Powering Off on page 58), limit
the acceleration and max speed (see Speed Limit Mode on page 132), and
turn the following features on or off:

example, the suspension does not lower if a
door is open.
Note: Your chosen Suspension Lowering and
Adaptive Suspension Damping settings are
saved to your driver profile (see Driver Profiles
on page 50).
Auto-Raising Suspension Auto-raising suspension saves you from
manually having to raise the suspension every
time you arrive at a frequently-used location
where you have previously raised the
suspension. Whenever you raise the
suspension to HIGH or VERY HIGH , Model X
saves the location. When you return to the
saved location, Model X raises the suspension and the instrument panel displays this
message:
Note: When returning to a saved location and
driving faster than the High and Very High
suspension settings allow, the suspension
does not raise until Model X slows down.
Note: After leaving a saved location, the
suspension may not lower until you are driving
faster than the speed threshold at which the
suspension lowers.
Note: If Model X reaches a saved location and
the existing suspension setting is already
higher than the level that has been saved for
that location, the ride height is not adjusted.
To remove an auto-raising location
If you do not want the suspension to auto- raise at a saved location, touch the X in the
auto-raising location status message that
displays at a saved location. Doing so removes
the auto-raise location and the suspension no
longer raises automatically when you arrive at
the location.
Note: Manually lowering the suspension to
STANDARD , LOW , or VERY LOW while at a
saved location also removes the auto-raising
location.
Jack Mode
Before jacking or lifting, set the suspension to
Jack mode to prevent the self-leveling that
occurs even when Model X is powered off.
Press the brake pedal, then touch Controls >
Suspension > Jack .
To deactivate, touch Jack again.
Note: Jack mode automatically cancels when
you drive over 7 km/h.
Note: Model X also sets Jack mode
automatically if it detects that the vehicle
cannot lower to its target height, or if it
detects that an object is supporting the
vehicle

Disable the Self-Leveling AirSuspension System
If Model X is equipped with the air suspension
system, it automatically self-levels, even when
power is off. To prevent damage, you must
activate Jack Mode to disable self-leveling:
1. Touch Controls > Suspension on the
touchscreen.
2. Press the brake pedal, then touch Very
High to maximize height.
3. Touch Jack.When Jack Mode is active, Model X
displays this red indicator light on
the instrument panel, along with a
message telling you that active
suspension is disabled.
Note: Jack Mode cancels when driving speed
exceeds 7 kph.
Warning: Failure to activate Jack Mode on
a vehicle equipped with the air
suspension system can result in the
vehicle becoming loose during transport,
which may cause significant damage.
Activate Transport Mode
Transport Mode keeps the parking brake
disengaged while winching Model X onto a
