When driving
GX460_CANADA (OM60F29U)
CAUTION
■When starting the vehicle
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 willresult in sudden acceleration that may lead to an accident that could result in
death or serious injury.
• When backing up, you may twist your body around, leading to a difficulty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only slightly. This allows you to depress the brake and accelerator pedals
properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay response in an emergency, resulting in an acci-
dent.
●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.
●Do not let the vehicle roll backwards while th e 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.

2-1. Driving procedures
GX460_CANADA (OM60F29U)
CAUTION
■When driving the vehicle
●If the smell of exhaust is noticed inside the vehicle, open the windows and check
that the back door is closed.
Large amounts of exhaust in the vehicle can cause driver drowsiness and an acci-
dent, resulting in death or a serious health hazard. Have the vehicle inspected by
your Lexus dealer immediately.
●Do not under any circumstances shift the shift lever to P while the vehicle is mov-
ing.
Doing so can cause significant damage to the driveline and may result in a loss of
vehicle control.
●Do not under any circumstances shift the shift lever to R while the vehicle is mov-
ing forward.
Doing so can cause significant damage to the driveline 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 insufficient engine braking, resulting in an accident.
●Do not turn the engine off while driving.
The power steering and brake booster will not operate properly if the engine is
not running.
●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. 1 8 7 )
●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 that can cause accidents, resulting
in death or serious injury.

GX460_CANADA (OM60F29U)
CAUTION
■If you hear a squealing or scraping noise (brake pad wear limit indicators)
Have your Lexus dealer check and replace the brake pads as soon as possible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or
those of the brake discs are exceeded.
■When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any gear other than P or N, the vehicle may accelerate suddenly
and unexpectedly, causing 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.
●In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while the engine is running, and apply the parking
brake as necessary.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, always depress the brake pedal and securely
apply the parking brake as needed.
●Avoid revving or racing the engine. Running the engine at high speed while the
vehicle is stopped may cause the exhaust system to overheat, which could result
in a fire if combustible material is nearby.

2-3. Operating the lights and windshield wipers
GX460_CANADA (OM60F29U)
■Daytime running light system
●To make your vehicle more visible to other drivers, the headlights turn on auto-
matically (at a reduced intensity) whenever the engine is started and the parking
brake is released. Daytime running lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the switch.
●Compared to the headlights, the daytime running light system offers greater
durability and consumes less electricity, so it can help fuel economy.
■Headlight control sensor
■Automatic light off system
●When only the tail lights come on: The parking/front side marker, tail, license
plate and fog lights turn off if the “ENGINE START STOP” switch is turned to
ACCESSORY mode or turned off and the driver’s door is opened.
●When the headlights come on: The headlights, parking/front side marker, tail,
license plate and fog lights turn off 30 seconds after a door or the glass hatch is
opened and closed. (The lights turn off immediately if on the key is
pressed after all the doors are locked.)
To turn the lights on again, turn the “ENGINE START STOP” switch to IGNITION
ON mode, or turn the light switch off once and then back to
or .
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
