Before driving
CAUTION
lDo not attach any accessories other than genuine Lexus parts to the back door.
The power back door may not operate, causing itself to malfunction, or the back
door may fall closed again after it is opened.
lIn cases such as when replacing tires, make sure to turn off the power back door
main switch. Failure to do so may cause the back door to operate unintentionally
if the power back door switch is accidentally touched, resulting in hands and fin-
gers being caught and injured.
nJam protection function (vehicle with a power back door)
Observe the following precautions.
Failure to do so may cause death or serious injury.
lBe careful while the jam protection function is operating. Being hit by the back
door may result in an injury.
lIf anything obstructs the power back door while it is closing, the jam protection
function will cause the back door to automatically operate in the opposite direc-
tion. However, be careful not to jam body parts in the doorframe, as an injury may
result.
lNever use any part of your body to intentionally activate the jam protection func-
tion.
lThe jam protection function may not work if something gets caught just before
the back door fully closes. Be careful not to catch fingers or anything else.
lThe jam protection function may not work depending on the shape of the object
that is caught. Be careful not to catch fingers or anything else.
lThe sensors located on the right and left sides of the power back door detect
obstructions and prevent them from becoming jammed in the door. Some objects
may not be detected depending on their shape or how they are jammed. Be care-
ful not to get fingers or other body parts caught in the back door while it is oper-
ating as this may result in a serious injury.

2-1. Driving procedures

When driving
nDriving in the rain
lDrive carefully when it is raining, because visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
lDrive carefully when it starts to rain, because the road surface will be especially
slippery.
lRefrain from high speeds when driving on an expressway in the rain, because
there may be a layer of water between the tires and the road surface, preventing
the steering and brakes from operating properly.
nBreaking in your new Lexus
To extend the life of the vehicle, observing the following precautions is recom-
mended:
lFor the first 200 miles (300 km):
Avoid sudden stops.
lFor the first 500 miles (800 km):
Do not tow a trailer.
lFor the first 1000 miles (1600 km):

2-1. Driving procedures

When driving
CAUTION
lDo 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.
lDo not shift the shift lever to N while the vehicle is moving.
Doing so may cause insufficient engine braking, resulting in an accident.
lDo not turn the engine off while driving.
The power steering and brake booster will not operate properly if the engine is
not running.
lUse 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 5 9 )
lWhen stopped on an incline, use the brake pedal and parking brake to prevent
the vehicle from rolling backward or forward, causing an accident.
lDo 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, resulting
in death or serious injury.
lAlways check that all passengers' arms, heads or other parts of their body are not
outside the vehicle, as this may result in death or serious injury.
lDo 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 not before driving at such speeds.

2-1. Driving procedures
CAUTION
lIf 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.
lThe exhaust system 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 vehicle 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.
nWhen taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift lever or
depress the accelerator pedal, this could cause an accident or fire due to 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.
nWhen braking the vehicle
lWhen the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one side
of the vehicle to brake differently than the other side. Also, the parking brake may
not securely hold the vehicle.
lIf the power brake assist function does not operate, do not follow other vehicles
closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be depressed
more firmly than usual. Also, the braking distance will increase.
lDo not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted brakes.
lThe 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.
If this happens, do not drive the vehicle. Have your brakes fixed immediately.
nIf the vehicle becomes stuck
Do not spin the wheels excessively when any of the tires is up in the air, or the vehi-
cle is stuck in sand, mud, etc. This may damage the driveline components or propel
the vehicle forward or backward, causing an accident.

2-4. Using other driving systems

When driving
CAUTION
nThe ABS does not operate effectively when
lTires with inadequate gripping ability are used (such as excessively worn tires on
a snow covered road).
lThe vehicle hydroplanes while driving at high speed on a wet or slick road.
nStopping distance when the ABS is operating will exceed that of normal condi-
tions
The ABS is not designed to shorten the vehicle’s stopping distance. Always main-
tain a safe distance from the vehicle in front of you in the following situations:
lWhen driving on dirt, gravel or snow-covered roads
lWhen driving with tire chains
lWhen driving over bumps in the road
lWhen driving over roads with potholes or roads with uneven surfaces
nTRAC may not operate effectively when
Directional control and power may not be achievable while driving on slippery road
surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.

236
2-4. Using other driving systems
CAUTION
nWhen the VSC is activated
The slip indicator light flashes and a warning buzzer sounds. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the indica-
tor light flashes and a buzzer sounds.
nWhen the TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are the systems to ensure vehicle stability and driving force, do not turn the
TRAC/VSC systems off unless necessary.
nReplacing tires
Make sure that all tires are of the same size, brand, tread pattern and total load
capacity. In addition, make sure that the tires are inflated to the recommended tire
inflation pressure level.
The ABS and VSC systems will not function correctly if different tires are installed
on the vehicle.
Contact your Lexus dealer for further information when replacing tires or wheels.
nHandling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect the driv-
ing assist systems, and may cause a system malfunction.
