CAUTION
Observe the following precautions.
Failure to do so may cause the driver's floor mat to slip, possibly interfering
with the pedals while driving. An unexpectedly high speed may result or it
may become difficult to stop the vehicle, leading to a serious accident.
When installing the driver's floor mat
Do not use floor mats designed for other models or different model year
vehicles, even if they are Lexus Genuine floor mats.
Only use floor mats designed for the driver's seat.
Always install the floor mat securely using the retaining hooks (clips) pro-
vided.
Do not use two or more floor mats on top of each other.
Do not place the floor mat bottom-side up or upside-down.
Before driving
Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this check
after cleaning the floor.
With the engine stopped and the shift
lever in P, fully depress each pedal to
the floor to make sure it does not inter-
fere with the floor mat.

Maintenance and care
IS F_EE
CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
When working on the engine compartment:
Keep hands, clothing, and tools away from the moving fan and engine
drive belt.
Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
Do not smoke, cause sparks or expose an open flame to fuel or the battery.
Fuel and battery fumes are flammable.
Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience discomfort, see a doctor.
When working near the electric cooling fan or radiator grille:
Be sure the “ENGINE START STOP” switch is OFF.
With the “ENGINE START STOP” switch in IGNITION ON mode, the
electric cooling fan may automatically start to run if the air conditioning is
on and/or the coolant temperature is high. (P. 374)
CAUTION
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in the eyes.

4-3. Do-it-yourself maintenance
IS F_EE
Tire rotation
It is not possible to rotate the tires, as the front and rear tire sizes are differ-
ent.
Tire replacement
P. 3 8 5
Low profile tires
Generally, low profile tires will wear more rapidly and tire grip performance
will be reduced on snowy and/or icy roads when compared to standard tires.
Be sure to use snow tires or tire chains
* on snowy and/or icy roads and
drive carefully at a speed appropriate for road and weather conditions.
*: Tire chains cannot be mounted on 19-inch tires.
CAUTION
When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train, as well as dan-
gerous handling characteristics, which may lead to an accident resulting in
death or serious injury.
Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
Do not use tire sizes other than those recommended by Lexus.
Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
Do not mix summer, all season and snow tires.
Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.

Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
To prevent battery discharge
Turn off the headlights and the audio system while the engine is off.
Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
Charging the battery
The electricity stored in the battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects
of certain electrical appliances. If the vehicle is left for a long time, the
battery may discharge, and the engine may be unable to start. (The bat-
tery recharges automatically during driving.)
Start the engine of the second vehicle. Increase the
engine speed slightly and maintain at that level for
approximately 5 minutes to recharge the battery of your
vehicle.
Open and close any of the doors with the “ENGINE
START STOP” switch OFF.
Maintain the engine speed of the second vehicle and turn
the “ENGINE START STOP” switch to IGNITION ON
mode, then start the vehicle's engine.
Once the vehicle’s engine has started, remove the jumper
cables in the exact reverse order in which they were con-
nected.
Once the engine starts, have the vehicle checked at any autho-
rized Lexus dealer or repairer, or another duly qualified and
