CAUTION
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce
your ability to control the vehicle, resulting in an accident.
●Sudden changes in engine speed, such as engine braking caused by up-shifting
or down-shifting, may cause the vehicle to skid, resulting in an accident.
●After driving through a puddle, lightly depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the brakes from
functioning properly. If the brakes on only one side are wet and not functioning
properly, steering control may be affected, resulting in an accident.
■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 not 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.

CAUTION
■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.
Doing 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 plasticmaterial 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 unattended 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 it is
snowing. If snowbanks build up around the vehicle while the engine is running,
exhaust gases may collect and enter the vehicle. This may lead to death or a seri-
ous health hazard.
■Exhaust gases
Exhaust gases include harmful carbon monoxi de (CO) that is colorless and odor-
less. Inhaling exhaust gases may lead to death or a serious health hazard.
●If the vehicle is in a poorly ventilated area, stop the engine. In a closed area, such
as a garage, exhaust gases may collect and enter the vehicle. This may lead to
death or a serious health hazard.
●The exhaust should be checked occasionally. If there is a hole or crack caused by
corrosion, damage to a joint or abnormal exhaust noise, be sure to have the vehi-
cle inspected and repaired by your Lexus dealer. Failure to do so may allow
exhaust gases to enter the vehicle, resulting in death or a serious health hazard.
