Precautions While Driving
Avoid driving in deep water and on flooded roads. This can damage the engine or
driveline, or cause electrical component failure.
If there is a strong impact with something under the vehicle, stop in a safe location.
Check the underside of the vehicle for damage or any fluid leaks.
■In Rain
■Other Precautions
1 Precautions While Driving
NOTICE
Do not change the transmission while pressing the
accelerator pedal. You could damage the
transmission.
NOTICE
If you repeatedly turn the steering wheel at an
extremely low speed, or hold the steering wheel in
the full left or right position for a while, the electric
power steering (EPS) system heats up. The system
goes into a protective mode, and limits its
performance. The steering wheel becomes harder
and harder to operate. Once the system cools down,
the EPS system is restored.
Repeated operation under these conditions can
eventually damage the system.
If the power mode is set to ACCESSORY while
driving, the engine will shut down and all steering
and brake power assist functi ons will stop, making it
difficult to control the vehicle.
Do not select
( N while driving as you will lose engine
braking (and accelera tion) performance.
During the first 600 miles (1,000 km) of operation,
avoid sudden acceleration or full throttle operation so
as not to damage the engine or powertrain.
Avoid hard braking for the first 200 miles (300 km).
You should also follow this when the brake pads are
replaced.
