Breaking in your new Lexus
To extend the life of the vehicle, observing the following precautions is rec-
ommended:
For the first 300 km (186 miles):
Avoid sudden stops.
For the first 800 km (500 miles):
Do not tow a trailer.
For the first 1000 km (621 miles):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.
Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of
brake system needs bedding-down of the brake shoes periodically or when-
ever the parking brake shoes and/or drum are replaced. Have any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional
perform the bedding down operation.
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availabil-
ity of the correct fuel. (P. 838)

Trailer towing
Weight limits
Check the allowable towing capacity, GVM (Gross Vehicle
Mass), MPAC (Maximum Permissible Axle Capacity), and per-
missible draw bar load before towing. (P. 836)
Towing hitch/bracket
Lexus recommends the use of the Lexus hitch/bracket for your
vehicle. Other products of a suitable nature and comparable qual-
ity may also be used.
To prevent an accident
The handling of the vehicle will feel different when towing a
trailer. Beware of the 3 most common causes of towing-related
accidents: driver error, excessive speed, and overloading.
The strain of towing a trailer will have a negative impact on the
running performance, handling, fuel consumption and endurance
of your vehicle. Use the vehicle features in the correct manner and
operate the vehicle with care for safer driving and optimal comfort.
Damage and/or malfunctions that occur as a result of towing per-
formed for commercial purposes are not covered by the Lexus war-
ranty.
Ask your local authorized Lexus dealer or repairer, or another duly
qualified and equipped professional for further details before tow-
ing, as there are additional legal requirements in some countries.
