LX570_OM_OM60L96U_(U) CAUTION■
Exhaust gases
Exhaust gases include harmful carbon monoxide (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 ar ea, 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 ex haust 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, result ing in death or a serious health hazard.■
When taking a nap in the vehicle
Always turn the engine off.
Otherwise, you may accidentally move the shift lever or depress the accelerator
pedal, which could cause an accident or fire due to abnormal engine overheating.
Additionally, if the vehicle is parked in a poorly ventilated area, exhaust gases may
collect and enter the vehicle, leading to death or a serious health hazard. ■
When braking the vehicle ●
When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and may cause one side of
the vehicle to brake differently than the other side. Also the parking brake may
not securely hold the vehicle. ●
If the power brake assist function does not operate, do not follow other vehicles
closely and avoid hills or shar p turns that require braking.
In this case, braking is still possible, but the brake pedal should be depressed
more firmly than usual. Also, th e braking distance will increase.
Have your brakes fixed immediately. ●
Do not pump the brake peda l if the engine stalls.
Each push on the pedal uses up the reserve for the power-assisted brakes. ●
The brake system consists of 2 individual hydraulic systems: If one of the systems
fails, the other will still operate. In this case, the brake pedal should be depressed
more firmly than usual and the braking distance will increase.
Have your brakes fixed immediately.
