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.

When trouble arises

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
id fil iblSTEP2
