2-5. Driving information
lWhen restarting after parking on a slope:
With the transmission in the P position, start the engine. Be sure
to keep the brake pedal depressed.
Shift into 3, 2, 1, or the R position (if reversing).
Release the parking brake and brake pedal, and slowly pull or
back away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.
nBefore towing
Check that the following conditions are met:
lThe vehicle's tires are properly inflated. (→P. 4 8 7 )
lTrailer tires are inflated according to the trailer manufacturer's recommendation.
lAll trailer lights work.
lAll lights work each time you connect them.
lThe trailer ball is set up at the proper height for the coupler on the trailer.
lThe vehicle remains level when a loaded or unloaded trailer is hitched. Do not
drive if the vehicle is not level, and check for improper tongue load, overloading,
worn suspension, or other possible causes.
lThe trailer cargo is securely loaded.
lThe rear view mirrors conform to all applicable federal, state/provincial or local
regulations. If they do not, install rear view mirrors appropriate for towing pur-
poses.
nBreak-in schedule
If your vehicle is new or equipped with any new power train components (such as
an engine, transmission, differential and wheel bearing), Lexus recommends that
you do not tow a trailer until it has been driven for over 500 miles (800 km).
However, avoid full throttle acceleration.
nMaintenance
lIf you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (See “Warranty and Services Guide”, “Owner's Manual Sup-
plement” or “Scheduled Maintenance”.)
lRetighten the fixing bolts of the towing ball and bracket after approximately 600
miles (1000 km) of trailer towing.
