■Operational conditions
The pre-crash safety system is enabled and determines that the possibility of
a frontal collision with a vehicle is high.
Each function is operational at the following speeds:
● Pre-crash warning:
• Vehicle speed is approximately 15 to 140 km/h (10 to 85 mph).
• The relative speed between your vehicle and a preceding vehicle is
approximately 15 km/h (10 mph) or more.
● Pre-crash brake assist:
• Vehicle speed is approximately 30 to 80 km/h (20 to 50 mph).
• The relative speed between your vehicle and a preceding vehicle is
approximately 30 km/h (20 mph) or more.
● Pre-crash braking:
• Vehicle speed is approximately 10 to 80 km/h (7 to 50 mph).
• The relative speed between your vehicle and a preceding vehicle is
approximately 10 km/h (7 mph) or more.
The system may not operate in the following situations:
● If a battery terminal has been disconnected and reconnected and then the
vehicle has not been driven for a certain amount of time
● If the shift lever is in R
● If VSC is disabled (only the pre-crash warning function will be operational)
■ Cancelation of the pre-crash braking
● If either of the following occur while the pre-crash braking function is operat-
ing, it will be canceled:
• The accelerator pedal is depressed strongly.

Winter driving tips
●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 specified size and brand, and that chains
match the size of the tires.
Perform the following according to the driving conditions:
● 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 windshield.
● Check for and remove any excess ice or snow that may have accu-
mulated 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.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.
