2022 Jaguar XF Speed Limiter
SPEED LIMITER SAFETY
Make sure the following warnings have been read and fully understood before using a speed limiter. Failure to use the speed limiter safely could result in an accident, leading to serious injury or death.
Speed limiters are driving aids only. Always drive with due care and attention, and in a manner which is safe for the vehicle, its occupants, and other road users. The driver should still observe all road signs, road markings, and situations that are not detected or recognized by the speed limiter systems. Driving without due care and attention greatly increases the risk of an accident.
In certain conditions, such as a steep downhill slope, the vehicle’s speed may exceed the set speed limit. Driver intervention may be required. Driving at speeds above the set speed limit may infringe on local laws.
Speed limiters are convenience features only. Speed limiters do not remove the driver’s responsibility to adhere to the legal road speed limit.
SPEED LIMITER OVERVIEW
Make sure the relevant safety warnings have been read and understood before driving the vehicle. See SPEED LIMITER SAFETY.
Two types of speed limiter are available:
- Speed limiter.
- Adaptive speed limiter.
The speed limiter allows the driver to manually restrict the vehicle’ maximum speed. When a maximum speed limit is set, the vehicle responds normally until the set speed is reached. At this point, the vehicle stops accelerating.
The adaptive speed limiter works in conjunction with the traffic sign recognition system and the navigation system to restrict the vehicle’ maximum speed. The maximum speed is set based on the information received from both of these systems. If the system cannot determine a valid maximum speed, the last known set speed limit is used.
To activate the speed limiter, see SPEED LIMITER.
To activate the adaptive speed limiter, see ADAPTIVE SPEED LIMITER.
Press and hold the CANCEL button on the steering wheel to switch between the speed limiter and the adaptive speed limiter.
Speed limiters are not available when cruise control or adaptive cruise control is in operation. When the vehicle is first switched on, the vehicle reverts to whichever system was used previously.

Make sure the relevant safety warnings have been read and understood before driving the vehicle. See SPEED LIMITER SAFETY.
The speed limiter controls are located on the right side of the steering wheel:
- LIM button.
- CANCEL button.
- SET+ position.
- SET- position.
- Speed control switch and RES button.
Press the LIM button (1) on the steering wheel controls to toggle between speed limiter and cruise control. The instrument panel displays the information lamp for the selected system. See SPEED LIMITER (GREEN) and CRUISE CONTROL (GREEN).
The speed limiter does not operate until activated.
The speed limiter function is not available in some markets.
Move the speed control switch (5) upward to the SET+ position (3), and release, to activate the speed limiter. The vehicle’s speed is limited to the speed it was traveling at when the switch was moved. If the vehicle is stationary when the speed control switch is moved, the system sets the speed limit to 10 mph (16 km/h).
The LIM icon on the steering wheel controls illuminates to confirm that the system is operational.
Move the speed control switch upward to the SET+ position to increase the vehicle’s speed limit:
- A single movement of the switch increases the vehicle’s speed limit by 1 mph (2 km/h).
- Hold the speed control switch in the SET+ position to increase the vehicle’s speed limit by 5 mph (10 km/h).
Move speed control switch downward to the SET- position (4) to reduce the vehicle’s speed limit.
- A single movement of the switch reduces the vehicle’s speed limit by 1 mph (2 km/h).
- Hold the speed control switch in the SET- position to reduce the vehicle’s speed limit by 5 mph (10 km/h).
Press the CANCEL button (2) to suspend speed limiter operation.
To reactivate the speed limiter:
- Press the RES button (5) to activate the speed limiter at the speed set previously.
- Move the speed control switch upward to the SET+ position, and release, to activate the speed limiter operation at the vehicle’s current speed.
The speed limiter’s set speed can be overridden if a higher level of acceleration is required. Fully press the accelerator pedal to accelerate past the speed limiter’s set speed. When the vehicle’s speed drops below the speed limiter’s set speed, any speed limitations are reapplied.
SPEED LIMITER LIMITATIONS
The driver may notice the effects of the speed limiter if the vehicle’s speed is close to the set speed limit.
The instrument panel displays messages to inform the driver of any performance or system issues.
ADAPTIVE SPEED LIMITER
Make sure the relevant safety warnings have been read and understood before driving the vehicle. See SPEED LIMITER SAFETY.
The adaptive speed limiter does not operate if the traffic sign recognition system is not operating. See TRAFFIC SIGN RECOGNITION.
The speed limiter controls are located on the right side of the steering wheel:
- LIM button.
- CANCEL button.
- SET+ position.
- SET- position.
- Speed control switch and RES button.
Press the LIM button (1) to toggle between adaptive speed limiter and cruise control. The instrument panel displays the information lamp for the selected system. SeeSPEED LIMITER (GREEN), ADAPTIVE SPEED LIMITER (GREEN), and CRUISE CONTROL (GREEN).
The LIM icon on the steering wheel controls illuminates to confirm that the system is operational.
If the speed limiter information lamp is displayed, press and hold the CANCEL button (2). The adaptive speed limiter information lamp replaces the speed limiter information lamp to confirm that the adaptive speed limiter has been selected.
The adaptive speed limiter does not operate until activated. Move the speed control switch (5) to the SET+ position (3) and release, or press the RES button (5) to activate the adaptive speed limiter. The Head-Up Display (HUD) and instrument panel display the detected speed limits as icons.
If the system detects a speed limit lower than the current vehicle speed, it automatically slows the vehicle to meet the speed limit. Press the RES button switch to increase the rate of deceleration.
If the system detects a speed limit higher than the current vehicle speed, it allows the driver to accelerate up to the speed limit. Press the RES button to increase the rate of acceleration.
The adaptive speed limiter only activates if the vehicle’s speed is less than 20 mph (30 km/h) over the set speed. If the vehicle’s speed is 20 mph (30 km/h) above the set speed, the instrument panel displays a warning message and the system does not activate.
Press the CANCEL button to suspend adaptive speed limiter operation.
Press the RES button, or move the speed control switch to the SET+ position and release, to resume adaptive speed limiter operation.
The adaptive speed limiter’s detected speed limit can be overridden if rapid acceleration is required. Fully press the accelerator pedal to accelerate past the adaptive speed limiter’s set speed. When the vehicle’s speed drops below the adaptive speed limiter’s detected speed limit, any speed limitations are reapplied.
The system’s detected speed limit can be adjusted, if required, to control the vehicle’s speed at just above or below the detected speed limit. The maximum adjustment is 5 mph (10 km/h) above or below the detected speed limit
Move the speed control switch upwards to the SET+ position to increase the vehicle’s speed limit:
- A single movement of the switch increases the vehicle’s speed limit by 1 mph (2 km/h).
- Hold the speed control switch in the SET+ position to increase the vehicle’s speed limit by 5 mph (10 km/h).
Move speed control switch downward to the SET- position (4) to reduce the vehicle’s speed limit.
- A single movement of the switch reduces the vehicle’s speed limit by 1 mph (2 km/h).
- Hold the speed control switch in the SET- position to reduce the vehicle’s speed limit by 5 mph (10 km/h).
Any adjustments to the adaptive speed limiter’s detected speed limit are lost if the speed limiter is activated. Adjustments are also lost if the vehicle’s ignition is switched off.
ADAPTIVE SPEED LIMITER LIMITATIONS
The adaptive speed limiter:
- Does not apply speed limits below 10 mph (16 km/h). For detected speed limits below 10 mph (16 km/h), the system sets a speed limit of 10 mph (16 km/h).
- Displays — in the instrument panel if the traffic sign recognition system cannot determine a valid speed limit. The last known valid speed limit is applied if this occurs.
- May allow vehicle speed to increase in certain conditions, e.g., when traveling downhill. If the vehicle’s speed rises by more than 2 mph (3.5 km/h) above the detected speed limit, the instrument panel displays a warning message. If the vehicle’s speed rises by more than 4 mph (7 km/h) above the detected speed limit for 4 seconds, a chime also sounds.
- Performance and accuracy are only as good as the information provided by the traffic sign recognition system.
- Performance and accuracy are only as good as the information provided by the navigation system. Always make sure the navigation system is operating correctly and is using the latest software.
- Does not operate if the traffic sign recognition system is unavailable. If the adaptive speed limiter is unavailable the system reverts to standard speed limiter operation using the last detected speed limit. See SPEED LIMITER OVERVIEW.
The instrument panel displays messages to inform the driver of any performance or system issues.
