When starting off on an uphill
The hill-start assist control will activate. (P. 286)
Driving in the rain
Drive carefully when it is raining, because visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.
Drive carefully when it starts to rain, because the road surface will be especially
slippery.
Refrain from high speeds when driving on an expressway in the rain, because
there may be a layer of water between the tires and the road surface, preventing
the steering and brakes from operating properly.
Engine speed while driving
In the following conditions, the engine speed may become high while driving.
This is due to automatic up-shifting control or down-shifting implementation to
meet driving conditions. It does not indicate sudden acceleration.
The vehicle is judged to be driving uphill or downhill
When the accelerator pedal is released
When the brake pedal is depressed while sport mode is selected
Breaking in your new Lexus
To extend the life of the vehicle, observing the following precautions is recom-
mended:
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 whenever 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 bed-
ding down operation.
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. (P. 564)
