1904-1. Before driving
WARNING
●Do not leave a door or window open if the curved glass is coate d with a
metallized film such as a silver-colored one. Reflected sunligh t may cause
the glass to act as a lens, causing a fire.
● Always apply the parking brake, shift the shift lever to P, stop the engine
and lock the vehicle.
Do not leave the vehicle unattended while the engine is running .
If the vehicle is parked with the shift lever in P but the park ing brake is not
set, the vehicle may start to move, possibly leading to an acci dent.
● Do not touch the exhaust pipes while the engine is running or i mmediately
after turning the engine off.
Doing so may cause burns.
● 4WD models: If the shift lever is moved before the “4LO” indicator turns
on/off, the transfer mode may not be shifted completely. The tr ansfer mode
disengages both the front and rear driveshafts from the powertrain and
allows the vehicle to move regardless of the shift position. (A t this time, the
indicator blinks and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in
P. You or someone else could be seriously injured. You must complete the
shifting of the transfer mode. ( P. 315)
■ When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift
lever or depress the accelerator pedal, this could cause an acc ident or fire
due to engine overheating. Additionally, if the vehicle is park ed in a poorly
ventilated area, exhaust gases may collect and enter the vehicl e, leading to
death or a serious health hazard.
■ When braking
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this ma y cause
one side of the vehicle to brake differently than the other sid e. Also, the
parking brake may not securely hold the vehicle.
● If the brake booster device does not operate, do not follow oth er vehicles
closely and avoid hills or shar p turns that require braking.
In this case, braking is still possible, but the brake pedal sh ould be
depressed more firmly than usual. Also, the braking distance wi ll increase.
Have your brakes fixed immediately.
● Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
● The brake system consists of 2 individual hydraulic systems; if one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking dist ance will
increase. Have your brakes fixed immediately.

Driving
■Operation of the engine switch
●If the switch is not pressed shortly and firmly, the engine swi tch mode may
not change or the engine may not start.
● If attempting to restart the engine immediately after turning t he engine
switch off, the engine may not start in some cases. After turni ng the engine
switch off, please wait a few seconds before restarting the eng ine.
■ If the smart key system has been d eactivated by a customized setting
P. 523
WARNING
■ When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumsta nces.
Doing so may cause an accident resulting in death or serious in jury.
■ Caution while driving
If engine failure occurs while the vehicle is moving, do not lo ck or open the
doors until the vehicle reaches a safe and complete stop. Other wise, the
steering lock function will activate and this may lead to an ac cident, result-
ing in death or serious injury.
■ Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving th e vehicle,
press and hold the engine switch for more than 2 seconds, or pr ess it briefly
3 times or more in succession. ( P. 475)
However, do not touch the engine switch while driving except in an emer-
gency. Turning the engine off while driving will not cause loss of steering or
braking control, however, power assist to the steering will be lost. This will
make it more difficult to steer smoothly, so you should pull ov er and stop the
vehicle as soon as it is safe to do so.
■ When parking (except for New Caledonia)
Exhaust gases include harmful carbon monoxide (CO), which is colorless
and odorless. Observe the following precautions.
Failure to do so may cause exhaust gases to enter the vehicle a nd may
lead to an accident caused by light-headedness, or may lead to death or a
serious health hazard.
● If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the engine.
● Do not leave the vehicle with the engine running for a long tim e. If such a
situation cannot be avoided, park the vehicle in an open space and ensure
that exhaust fumes do not enter the vehicle interior.
● Do not leave the engine running in an area with snow build-up, or where it
is snowing. If snowbanks build up around the vehicle while the engine is
running, exhaust gases may collect and enter the vehicle.

Intuitive parking assist
■Types of sensors
■Intuitive parking assist switch
Turns the intuitive parking
assist on/off
When on, the indicator light
comes on to inform the driver
that the system is operational.
: If equipped
The distance from your vehicle to nearby obstacles when paral-
lel parking or maneuvering into a garage is measured by the
sensors and communicated via t he multi-information display
and buzzer. Always check the surrounding area when using this
system.

■Sensor operation and di stance to an obstacle
The system operates when the vehi cle approaches an obstacle, as

When 2 or more obstacles are detected simultaneously, the buzze r sys-
tem responds to the nearest zone.

■The intuitive parking assist can be operated when
●Front corner sensors:
• The engine switch is in ON.
• The shift lever is in R.
• The shift lever is not in P or R and vehicle speed is less than about 6 mph
(10 km/h).
● Rear corner and rear center sensors:

P. 494, 495
■ Certification (Canada only)
This ISM device complies with Canadian ICES-001.
WARNING
■When using the intuitive parking assist
Observe the following precautions.
Failure to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.
● Do not use the sensor at speeds in excess of 6 mph (10 km/h).
● The sensors’ detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle ( especially
the sides of the vehicle) for safety, and drive slowly, using t he brake to
control the vehicle’s speed.
● Do not install accessories within the sensors’ detection areas.
