Driving
RX350/RX350L_U WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury. ■
When starting the vehicle
Always keep your foot on the brake pedal while stopped engine running. This prevents
the vehicle from creeping. ■
When driving the vehicle ●
Do not drive if you are unfamiliar with the location of the brake and accelerator ped-
als to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal will
result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to difficulty in operat-
ing the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving po sture even when moving the vehicle only
slightly. This allows you to depress th e brake and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using
your left foot may delay re sponse in an emergency, resulting in an accident.●
Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby. ●
During normal driving, do not turn off the engine. Turning the engi ne off while driving
will not cause loss of steering or braking control, but the power assist to these systems
will be lost. This will make it more difficult to steer and brake, so you should pull over
and stop the vehicle as soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way:  P. 645●
Use engine braking (downshift) to maintain a safe speed when driving down a steep
hill.
Using the brakes continuously may cause th e brakes to overheat and lose effective-
ness. (  P. 240)●
Do not adjust the positions of the steering wheel, the seat, or the inside or outside rear
view mirrors while driving.
Doing so may result in a loss of vehicle control. ●
Always check that all passengers’ arms, he ads or other parts of their body are not
outside the vehicle. ●
AWD models: Do not drive the vehicle off-road.
This is not an AWD vehicle designed for of f-road driving. Proceed with all due cau-
tion if it becomes unavoidable to drive off-road. ●
Do not drive across a river or through other bodies of water.
This may cause electric/elect ronic components to short ci rcuit, damage the engine or
cause other serious damage to the vehicle. ●
Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do not
drive over 85 mph (140 km/h) unless your vehicle has high-speed capability tires.
Driving over 85 mph (140 km/h ) 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 no t before driving at such speeds.
