Be careful not to spill beverages over the audio system.

DRIVING TIPS
182Do not rest your foot on the brake pedal while driving. It
can cause dangerous overheating, needless wear, and poor
fuel economy.
To drive down a long or steep hill, reduce your speed and
downshift. Remember, if you ride the brakes excessively,
they may overheat and not work properly. See page 163.
Be careful when accelerating, upshifting, downshifting or
braking on a slippery surface. The abrupt change in engine
speed, such as sudden acceleration or engine braking, could
cause the vehicle to spin or skid.
Do not drive in excess of the speed limit. Even if the legal
speed limit permits it, do not drive over 140 km/h (85 mph)
unless your vehicle has highspeed capability tires.
Driving over 140 km/h (85 mph) may result in tire failure,
loss of control and possible injury. Be sure to consult a tire
dealer to determine whether the tires on your vehicle are
highspeed capability tires or not before driving at such
speeds.
Do not continue normal driving when the brakes are wet.
If they are wet, your vehicle will require a longer stopping
distance, and it may pull to one side when the brakes are
applied. Also, the parking brake will not hold the vehicle
securely.
WINTER DRIVING TIPS
Make sure you have ethyleneglycol antifreeze in the radiator.
NOTICE
Do not use alcohol type antifreeze.
Check the condition of the battery and cables.
Cold temperatures reduce the capacity of any battery, so it must be
in top shape to provide enough power for winter starting. Page 253
tells you how to visually inspect the battery. Your Lexus dealer and
most service stations will be pleased to check the battery charge
level.
Make sure the engine oil viscosity is suitable for the cold weather.
See page 232 for recommended viscosity. Leaving a heavy summer
oil in your vehicle during winter months may cause harder starting.
If you are not sure about which oil to use, call your Lexus dealer
they will be pleased to help.
Check the electronic ignition system for loose connections or
obvious damage.
Keep the door locks from freezing.
Squirt lock deicer or glycerine into the locks to keep them from
freezing.
