When stopping the engine with the shift lever in a position other than P
If the engine is stopped with the shift lever in a position other than P, the
“ENGINE START STOP” switch will not be turned off but instead be
turned to ACCESSORY mode. Perform the following procedure to turn
the switch off:
Check that the parking brake is set.
Shift the shift lever to P.
Check that the indicator on the “ENGINE START STOP” switch
is illuminated in amber and then press the “ENGINE START
STOP” switch once.
Check that the indicator on the “ENGINE START STOP” switch
is off.
■Auto power off function
When the shift lever is in P, if the vehicle is left in ACCESSORY or IGNITION ON
mode with the engine not running for more than 20 minutes (ACCESSORY mode)
or one hour (IGNITION ON mode), the “ENGINE START STOP” switch will auto-
matically turn off. However, this function cannot entirely prevent battery discharge.
Do not leave the vehicle with the “ENGINE START STOP” switch in ACCESSORY
or IGNITION ON mode for long periods of time when the engine is not running.

■Raindrop sensor
●If the wiper switch is turned to the position while the “ENGINE START
STOP” switch is in IGNITION ON mode, the wipers will operate once to show
that AUTO mode is activated.
●When the sensor sensitivity ring is turned toward high while in AUTO mode, the
wipers will operate once to indicate that the sensor sensitivity is enhanced.
●If the temperature of the raindrop sensor is 90°C (194°F) or higher, or -15°C
(5°F) or lower, automatic operation may not occur. In this case, operate the wip-
ers in any mode other than AUTO.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
CAUTION
■Caution regarding the use of windshield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched or the
windshield is subject to vibration in AUTO mode. Take care that your fingers etc. do
not become caught in the windshield wipers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes warm. The
fluid may freeze on the windshield and cause low visibility. This may lead to an acci-
dent, resulting in death or serious injury.
●The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.

NOTICE
■To prevent water damage
Take all necessary safety measures to ensure that water damage to the engine or
other components does not occur.
●Water entering the engine air intake will cause severe engine damage.
●Water entering the automatic transmission will cause deterioration in shift quality,
locking up of your transmission accompanied by vibration, and ultimately dam-
age.
●Water can wash the grease from wheel bearings, causing rusting and premature
failure, and may also enter the differentials, transmission and transfer case (AWD
models), reducing the gear oil’s lubricating qualities.
■When you drive through water
If driving through water, such as when crossing shallow streams, first check the
depth of the water and the bottom of the stream for firmness. Drive slowly and avoid
deep water.
■Inspection after off-road driving
●Sand and mud that has accumulated around brake discs may affect braking effi-
ciency and may damage brake system components.
●Always perform a maintenance inspection after each day of off-road driving that
has taken you through rough terrain, sand, mud, or water.

Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions.
■Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
●Have a service technician inspect the condition of the battery.
●Have the vehicle fitted with four snow tires or purchase a set of
tire chains for the front tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
■Before driving the vehicle
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is fro-
zen. 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 windshield.
●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.
