Driving
“For Climate Control”
• The air conditioning system is being used when the ambient
temperature is high or low.
 If the difference between the set
temperature and cabin temperature
becomes small, the system will be
enabled.
• The windshield defogger is on.
●When the engine automatically
restarts while stopped by the Stop
& Start system
“In Preparation”
• The brake pedal has been depressed further or pumped.
 The system will be enabled after
the engine runs and the brake
booster vacuum reaches a predeter-
mined level.
“For Climate Control”
• The air conditioning system has been turned on or is being used.
• The windshield defogger has been turned on.
“Battery Charging”
• The battery charge may be low.
 The system will be enabled after
the engine runs to sufficiently

■When the buzzer sounds
If the driver's door is opened when
the engine is stopped by the Stop &
Start system and the shift lever is in
D, a buzzer will sound and the Stop
& Start system indicator will flash. To
stop the buzzer, close the driver's
door.
■The Stop & Start system protec-
tion function
●When the volume of the audio
system is excessively high, sound
output from the audio system may
suddenly be cut off in order to reduce battery consumption. To
prevent the audio system from
being cut off, keep the volume of
audio system at a moderate level.
If the audio system has been cut
off, turn the engine switch off, wait
for 3 seconds or more and then
turn it to ACC or
ON to re-enable
the audio system.
●The audio system may not be acti-
vated if the battery terminals are
disconnected and then recon-
nected. If this occurs, turn the
engine switch off and then repeat
the following operation twice to
activate the audio system nor-
mally.
• Turn the engine switch to ON and then to OFF.
■Replacing the battery
 P.485
■If the Stop & Start cancel indica-
tor flashes continuously
The system may be malfunctioning.
Have the vehicle inspected by your
Toyota dealer.
■If “Stop & Start System Mal-
function Visit Your Dealer” is
displayed on the multi-informa-
tion display
The system may be malfunctioning.
Have the vehicle inspected by your
Toyota dealer.
WARNING
■When the Stop & Start system
is operating
Make sure to disable the Stop &
Start system while the vehicle is in
a poorly ventilated area. If not dis-
abled, the engine may be auto-
matically restarted unexpectedly,
causing exhaust gases to collect
and enter the vehicle, possibly
resulting in death or a serious
health hazard.

3204-6. Driving tips
HIGHLANDER_U
Do not try to forcibly open a
window or move a wiper that
is frozen. Pour warm water
over the frozen area to melt
the ice. Wipe away the water
immediately to prevent it from
freezing.
 To ensure proper operation of
the climate control system
fan, remove any snow that
has accumulated on the air
inlet vents in front of the wind-
shield.
 Check for and remove any
excess ice or snow that may
have accumulated on the
exterior lights, vehicle’s roof,
chassis, around the tires or on
the brakes.
 Remove any snow or mud
from the bottom of your shoes
before getting in the vehicle.
Accelerate the vehicle slowly,
keep a safe distance between
you and the vehicle ahead, and
drive at a reduced speed suit-
able to road conditions.
 Park the vehicle and move
the shift lever to P without set-
ting the parking brake. The
parking brake may freeze up,
preventing it from being
released. If the vehicle is parked without setting the
parking brake, make sure to
block the wheels. Failure to
do so may be dangerous
because it may cause the
vehicle to move unexpectedly,
possibly leading to an acci-
dent.
When the parking brake is in auto-
matic mode, release the parking
brake after shifting the shift lever to
P. (
P.209)
 If the vehicle is parked without
setting the parking brake,
confirm that the shift lever
cannot be moved out of P
*.
*: The shift lever will be locked if it is
attempted to be sh ifted from P to
any other position without
depressing the brake pedal. If the
shift lever can be shifted from P,
there may be a problem with the
shift lock system. Have the vehi-
cle inspected by your Toyota
dealer immediately.
Use the correct tire chain size
when mounting the tire chains.
Chain size is regulated for each
tire size.

This information has been pre-
pared in accordance with regu-
lations issued by the National
Highway Traffic Safety Adminis-
tration of the U.S. Department of
Transportation.
It provides the purchasers
and/or prospective purchasers
of Toyota vehicles with informa-
tion on uniform tire quality grad-
ing.
Your Toyota dealer will help answer
any questions you may have as you
read this information.
■DOT quality grades
All passenger vehicle tires must
conform to Federal Safety
Requirements in addition to
these grades. Quality grades
can be found where applicable
on the tire sidewall between
tread shoulder and maximum
section width.
For example: Treadwear 200 Trac-
tion AA Temperature A
■Treadwear
The treadwear grade is a com-
parative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course.
For example, a tire graded 150 would wear one and a half (1 - 1/2)
times as well on the government
course as a tire graded 100.
The relative performance of tires
depends upon the ac
tual conditions
of their use. Performance may differ
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.
■Traction AA, A, B, C
The traction grades, from high-
est to lowest, are AA, A, B and
C, and they represent the tire’s
ability to stop on wet pavement
as measured under controlled
conditions on specified govern-
ment test surfaces of asphalt
and concrete.
A tire marked C may have poor
traction performance.
Warning: The traction grade
assigned to this tire is based on
braking (straight ahead) traction
tests and does not include corner-
ing (turning) traction.
■Temperature A, B, C
The temperature grades are A
(the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure.
