1684-1. Driving the vehicle
RAIZE_OM_General_BZ358E
⬛Starting off on an uphill
The hill-start assist control will be activated. (➞P. 232)
⬛Driving in the rain
⚫Drive carefully when it is raining, bec ause visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.
⚫Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
⚫Refrain from driving at high speeds on an expressway in the rain, because
there may be a layer of water between the tires an d the road surface, pre-
venting the steering and brakes from operating properly.
⬛Engine speed while driving (continuous ly variable transmission vehicles)
In the following conditions, the engine speed may become high while driving.
This is due to automatic up-shifting re striction or down-shifting implementa-
tion to meet driving conditions. It do es not indicate sudden acceleration.
⚫The vehicle is judged to be driving uphill or downhill
⚫When the accelerator pedal is released
⬛Engine power suppression control (Brake Override System)
When the accelerator pedal and the brake pedal are depressed simultane-
ously, the engine output may be suppressed.
▶Vehicles without TFT color multi-information display
⚫When the Brake Override System is op erating, the warning light turns on.
( ➞ P. 381)
▶Vehicles with TFT color multi-information display
⚫When the Brake Override System is op erating, the warning message is dis-
played. ( ➞P. 390)
⬛Idling before stopping the engine (turbo vehicles)
Immediately after driving at high-speed or climbing on a hill, idle the engine
for approx. 1 minute and then stop the engine in order to prevent the turbo
system from being damaged.
⬛Overheating
The following severe driving situations can cause overheating.
⚫Driving up a long uphill on a hot day
⚫Sudden deceleration or stop imme diately after high-speed driving

1734-1. Driving the vehicle
RAIZE_OM_General_BZ358E
WARNING
Driving
4
⚫Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.
⬛When parking the vehicle
⚫Do not leave glasses, cigarette lighters, aerosol cans, or carbonated bever-
age cans in the vehicle under the scorching sun.
Doing so may result in the following:
⦁ Gas may leak from a cigarette lighter or aerosol can, and may lead to a fire
⦁ The glasses with plastic lenses and plastic material may deform or crack
⦁ Carbonated beverage cans may fracture, causing the contents to spill over
the interior of the vehicle, and may al so cause a short circuit in the vehi-
cle’s electrical components
⚫Do not leave cigarette lighters in the vehi cle. If a cigarette lighter is in a stor-
age compartment or on the floor, it ma y be lit accidentally when luggage is
loaded or the seat is adjusted, causing a fire.
⚫Do not attach adhesive discs to the windshield or windows. Do not place
containers such as fragrance on the instrument panel or dashboard.
Adhesive discs or containers may act as lenses, causing a fire in the vehicle.
⚫Do not leave a door or window open if the curved glass is coated with a
metallized film such as a silver-colored one.
Reflected sunlight may cause the glass to act as a lens, causing a fire.
⚫For continuously variable transmission vehicles, always apply the parking
brake, set the shift lever to P, stop the engine, and lock the vehicle when
leaving the vehicle unattended.
Do not leave the vehicle unattende d while the engine is running.
If the vehicle is parked wi th the shift lever in P but the parking brake is not
set, the vehicle may start to move, possibly leading to an accident.
⚫Do not touch the exhaust pipes while th e engine is running or immediately
after turning the engine off.
Doing so may cause burns.
⬛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 accident or fire due to engine overheating. Addition-
ally, if the vehicle is parked in a poorly ventilated area, exhaust gases may enter
the vehicle, leading to death or a serious health hazard.

2344-5. Using the driving support systems
RAIZE_OM_General_BZ358E
⬛Activation of ABS/VSC
ABS/VSC does not work at low speeds. The operation is the same as the nor-
mal brake.
⬛Activation sound and vibration of the ABS, brake assist, VSC, TRC, and hill-
start assist control
⚫A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just after the vehicle
begins to move. This sound does not indicate that a malfunction has
occurred in any of these systems.
⚫Any of the following conditions may occur when the above systems are oper-
ating. None of them indicates that a malfunction has occurred.
⦁ Vibrations may be felt through th e vehicle body and steering wheel
⦁ A motor sound may be heard even after the vehicle has come to a stop
⦁ The brake pedal may pulsate slightly after the ABS is activated
⦁ The brake pedal may move down slightly after the ABS is activated
⬛EPS motor operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard, but this does not indicate a malfunction.
⬛Automatic reactivation of VSC and TRC
After turning the TRC and VSC systems off, the systems will return to the ready
state in the following situations:
⚫When the engine switch is turned to “OFF”
⚫If only the TRC system is turned off, when vehicle speed increases
If both the TRC and VSC systems are tu rned off, automatic reactivation will
not occur when vehicle speed increases.
⬛Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel ma y feel heavy as a result.
Should this occur, refrain from excessive steering input or stop the vehicle and
turn the engine off. It should re turn to normal within 10 minutes.
