DRIVING TIPS
471
CAUTION
Before driving off, make sure the parking brake is
fully released and that the parking brake reminder
light is off.
Do not leave your vehicle unattended while the
engine is running.
Do 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 392 or 403.
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 skid or spin.
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 high speed
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 high speed
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.
Vehicles with electronically modulated air
suspension: If you drive through water, such as when
crossing swallow streams, first check the depth of
the water and the bottom of the river bed of firmness,
put the vehicle height in the “HI” (high) mode with the
height select switch and then turn off the
electronically modulated air suspension by pushing
the height control switch. Drive your vehicle at 30
km/h (19 mph) or lower speed.

4. In case the tire inflation pressure is not within the
prescribed range, insert the compressed air from the
valve. In case of applying too much air, press the
center of the valve and release the air to adjust.
5. After completing the tire inflation pressure
measurement and adjustment, apply soapy water to
the valve and check for leakage.
6. Install the tire valve cap.
If a gauge and air pump are not available, have your
vehicle checked by your Lexus dealer.
CAUTION
Be sure to reinstall the tire valve caps. Without
the valve caps, dirt or moisture could get into
the valve core and cause air leakage. If the caps
have been lost, have new ones put on as soon
as possible.
Incorrect tire inflation pressure may waste fuel, reduce
the comfort of driving, reduce tire life and make your
vehicle less safe to drive.
If a tire frequently needs refilling, have it checked by
your Lexus dealer.
CAUTION
Keep your tires properly inflated. Otherwise, the
following conditions may occur and cause an
accident resulting in death or serious injuries.
Low tire pressure (underinflation) —
Excessive wear
Uneven wear
Poor handling
Possibility of blowouts from an overheated
tire
Poor sealing of the tire bead
Wheel deformation and/or tire separation
A greater possibility of tire damage from road
hazards
High tire pressure (overinflation) —
Poor handling
Excessive wear
Uneven wear
A greater possibility of tire damage from road
hazards
