Roadside Assistance - Towing & Jump Starting
Lexus RX450h roadside assistance may be handled like conventional Lexus vehicles except as noted in the following pages.
Lexus Roadside Assistance is available during the basic warranty period by contacting:
United States: (800) 255-3987
Canada: (800) 265-3987
Shift Lever:
Similar to many Lexus vehicles, the RX 450h uses a gated shift lever as shown in the illustration. However, the RX 450h shift lever includes an S position, allowing the selection of 6 levels of engine braking.
Towing:
RX450h models with all wheel drive must be towed with all four wheels off the ground. Models with front wheel drive must be towed with the front (drive) wheels off the ground. Failure to do so may cause serious damage to vehicle components. If it is not possible to determine whether the vehicle is AWD or FWD, tow the vehicle with all wheels off the ground.
- The vehicle may be shifted out of Park into Neutral by turning the ignition-on, depressing the brake, then moving the gated shift lever to N.
- If the shift lever cannot be moved out of Park, a shift lock release button is provided under the cover near the shift lever as shown in the illustration.
- If a tow truck is not available, in an emergency the vehicle may be temporarily towed using a cable or chain secured to the emergency towing eyelet or rear hooks. This should only be attempted on hard, paved roads for short distances at low speeds. The eyelet is located with the tools in the cargo area of the vehicle.
Electric Back Door Opener
- The RX 450h is equipped with an electric back door opener. In the event of 12 Volt power loss, the back door cannot be opened from the outside of the vehicle.
- The electric back door can be opened manually using the release as shown in the illustration.
Electric Fuel Door Opener
- The RX 450h is equipped with an electric fuel door opener. In the event of 12 Volt power loss, the fuel door can only be opened using the manual release located inside the cargo area.
Spare Tire

Jump Starting:
The 12 Volt auxiliary battery may be jump started if the vehicle does not start and the instrument cluster gauges are dim or off after depressing the brake pedal and pushing the power button.
The 12 Volt auxiliary battery is located in the cargo area. If the 12 Volt auxiliary battery is discharged, the rear back door cannot be opened. Instead, the vehicle can be jump started by accessing the remote positive 12 Volt auxiliary battery terminal in the engine compartment fuse box.
- Open the hood, and remove the engine room cover.
- Remove the fuse box cover, and open the positive terminal cover.
- Connect the positive jumper cable to the positive terminal.
- Connect the negative jumper cable to a solid ground.
- Place the smart key in proximity to the interior of the vehicle, depress the brake pedal, and push the power button.
NOTE:
If the vehicle does not recognize the smart key after connecting the booster battery to the vehicle, open and close the driver door when the vehicle is shut off.
If the smart key internal battery is dead, touch the Lexus emblem side of the smart key to the power button during the start sequence.
- The high voltage HV battery pack cannot be jump started.
Immobilizer & Anti-Theft Alarm
The RX 450h is equipped with a standard immobilizer system and an anti-theft alarm.
- The vehicle can be started only with a registered smart key.
- To disarm the anti-theft alarm, unlock the door by using the smart key button, hidden metal cut key, or door handle touch sensor. Turning the ignition-on or starting the vehicle will also disarm the anti-theft alarm.
