When driving
NOTICE
nWhen driving the vehicle
lDo not depress the accelerator and brake pedals at the same time during driving.
If the brake pedal is depressed while driving with the accelerator pedal
depressed, driving torque may be restrained.
lDo not use the accelerator pedal or depress the accelerator and brake pedals at
the same time to hold the vehicle on a hill.
nWhen parking the vehicle
Always shift the shift lever to P. Failure to do so may cause the vehicle to move or the
vehicle may accelerate suddenly if the accelerator pedal is accidentally depressed.
nAvoiding damage to vehicle parts
lDo not turn the steering wheel fully in either direction and hold it there for an
extended period of time.
Doing so may damage the power steering motor.
lWhen driving over bumps in the road, drive as slowly as possible to avoid damag-
ing the wheels, underside of the vehicle, etc.
nIf 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.
The rotor damage can 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.
nIf you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel
firmly and gradually depress the brake pedal to slow down the vehicle.
lIt may be difficult to control your vehicle.
lThe vehicle will make abnormal sounds.
lThe vehicle will behave abnormally.

When driving
Driving assist systems
To help enhance driving safety and performance, the following systems
operate automatically in response to various driving situations. Be aware,
however, that these systems are supplementary and should not be relied
upon too heavily when operating the vehicle.
nABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
nBrake assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation
nVSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces
nTRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads
nHill-start assist control
→P. 2 3 8
nEPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel
nActive torque control 4WD system (AWD models only)
Automatically switches from front-wheel drive to AWD (All-Wheel Drive)
according to driving conditions, helping to ensure reliable handling and
stability. Examples of conditions where the system will switch to AWD are
when cornering, going uphill, starting off or accelerating, and when the
road surface is slippery due to snow or rain etc.

When driving
All-wheel drive lock switch (AWD models)
nAll-wheel drive lock mode
lAll-wheel drive lock mode is canceled when the brakes are applied to ensure
the ABS and VSC systems operate effectively.
lAll-wheel drive lock mode is canceled when the vehicle speed exceeds 25 mph
(40 km/h).
All-wheel drive lock mode can be used when a large amount of drive power
needs to be applied to all the wheels, such as when the vehicle gets stuck in
mud and you need to free it.
Press the switch.
The torque of the engine is dis-
tributed to the rear wheels to
the maximum extent possible in
accordance with driving condi-
tions.
Pressing the switch again can-
cels all-wheel drive lock mode
and returns the active torque
control 4WD system to normal
mode. (→P. 2 3 1 )

NOTICE
nTo avoid serious damage to your vehicle
nTo prevent causing serious damage to the transmission and Active Torque Con-
trol 4WD system (AWD models)
Your vehicle is not designed to be dinghy towed (with 4 wheels on the
ground) behind a motor home.
Do not tow your vehicle with four wheels on
the ground.
2WD models: Never tow this vehicle from
the rear with the front wheels on the ground.
This may cause serious damage to the trans-

5-1. Essential information
NOTICE
nTo prevent body damage when towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
nTo prevent causing serious damage to the transmission and Active Torque Con-
trol 4WD system (AWD models) when towing using a wheel-lift type truck
nTo prevent damaging the vehicle when towing using a wheel-lift type truck
When raising the vehicle, ensure adequate ground clearance for towing at the
opposite end of the raised vehicle. Without adequate clearance, the vehicle could
be damaged while being towed.
nRecreational towing (behind motor home, etc.)
Never dinghy tow your vehicle to prevent causing serious damage to the Active
Torque Control 4WD system (AWD models) and transmission. (→P. 2 7 0 )
2WD models: Never tow this vehicle from
the rear with the front wheels on the ground.
This may cause serious damage to the trans-
mission. If towing from the rear, use a towing
dolly.
AW D m o d e l s : N e v e r t ow this vehicle with
any of the wheels on the ground. This may
