2-1. Driving procedures
■Breaking in your new Lexus
To extend the life of the vehicle, the following precautions are recommended to
observe:
●For the first 186 miles (300 km):
Avoid sudden stops.
●For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low gears.
• Do not drive at a constant speed for extended periods.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
correct fuel. (P. 3 7 2 )
CAUTION
■When starting the vehicle
With automatic transmission vehicles, always keep your foot on the brake pedal
while stopped with the 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
pedals to avoid depressing the wrong pedal.
Accidentally depressing the accelerator pedal instead of the brake pedal will
result in sudden acceleration that may le ad to an accident that could result in
death or serious injury.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
●With automatic transmission vehicles, do not let the vehicle roll backwards while
the shift lever is in a driving position, or roll forward while the shift lever is in R.
Doing so may cause the engine to stall or lead to poor brake and steering perfor-
mance, resulting in an accident or damage to the vehicle.
●If the smell of exhaust is noticed inside the vehicle, open the windows and check
that the trunk is closed.
Large amounts of exhaust in the vehicle can cause driver drowsiness and eventu-
ally, death. Have the cause of the problem inspected immediately.

2-1. Driving procedures

When driving
CAUTION
●Do not under any circumstances shift the shift lever to P, R or N (automatic trans-
mission vehicles) or R (manual transmission vehicles) while the vehicle is moving.
Doing so can cause significant damage to the transmission system and may result
in a loss of vehicle control.
●Do not shift the shift lever to N while the vehicle is moving.
Doing so may cause the engine brake to not operate properly and lead to an
accident.
●Do not turn the engine off while driving.
The brake booster system will not operate properly if the engine is not running.
●With manual transmission vehicles, do not leave the clutch pedal depressed or
use the half-clutch any more than necessary.
These actions will result in increased wear of the clutch, and may cause accidents
as a result of damage to the clutch.
●Use engine braking (downshift) to maintain a safe speed when driving down a
steep hill.
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. ( P. 9 3 )
●When stopped on an inclined surface, use the brake pedal and parking brake to
prevent the vehicle from rolling backward or forward and causing an accident.
●Be careful when driving on slippery surfaces, as the vehicle may spin or skid when
downshifting, rapidly accelerating, braking or turning.
●Do not adjust the position 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 that can cause accidents that may
result in death or serious injury.
●Always check that all passengers' arms, heads or other parts of their bodies are
not outside the vehicle, as this may result in death or serious injury.
●Do not drive the vehicle off-road.
This is not a AWD vehicle designed for real off-road driving. Proceed with all due
caution if it becomes unavoidable to drive off-road.
●Do not drive across river crossings or through other bodies of water.
This may cause electric/electronic comp onents to short circuit, damage the
engine or cause other serious damage to the vehicle.

2-1. Driving procedures
CAUTION
■When shifting the shift lever
With automatic transmission vehicles, be careful not to shift the shift lever with the
accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident and result in death or serious injury.
■When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any gear other than P (vehicles with an automatic transmission
only) or N the vehicle may accelerate suddenly and unexpectedly, and may cause
an accident.
●Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and
check that exhaust fumes do no t enter the vehicle interior.
●With automatic transmission vehicles, always keep a foot on the brake pedal
while the engine is running to prevent an accident caused by the vehicle moving.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehi-
cle when it is in the sun.
Failure to do so may result in the following.
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic material of eye glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of
the vehicle, and may also cause a short circuit in the vehicle's electrical com-
ponents.
●Always apply the parking brake, shift the shift lever to P (vehicles with an auto-
matic transmission only), stop the engine and lock the vehicle.
Do not leave the vehicle unattend ed while the engine is running.
●Do not touch the exhaust pipe while the engine is running or immediately after
turning the engine off.
Doing so may cause burns.
●Do not leave the engine running in an area with snow build up, or where snow is
expected to fall.
Exhaust gases may enter the vehicle and cause gas poisoning.

this case, immediately stop the vehicle in a safe place. Check the engine after it
has cooled completely. (P. 3 6 5 )
