The power mode does not
change from VEHICLE OFF
(LOCK) to ACCESSORY.
Why?
●The steering wheel may be locked.
●Move the steering wheel left and right
after pressing the ENGINE START/STOP
button.
Why does the brake pedal
pulsate slightly when
applying the brakes?This can occur when the ABS activates and does not indicate a
problem. Apply firm, steady pressure on the brake pedal. Never
pump the brake pedal.

The rear door cannot be
opened from inside the
vehicle. Why?Check if the childproof lock is in the
lock position. If so, open the rear
door with the outside door handle.
To cancel this function, slide the
lever up to the unlock position.
Why do the doors lock
after I unlocked the doors?If you do not open the doors within 30 seconds, the doors are
relocked automatically for security.

Before Driving
Driving Preparation
Check the following items before you start driving.
• Make sure there are no obstructions on the windows, door mirrors, exterior
lights, or other parts of the vehicle.
u Remove any frost, snow, or ice.
u Remove any snow on the roof, as this can slip down and obstruct your field of

or wheel components.
• Make sure the hood is securely closed.
u If the hood opens while driving, your front view will be blocked.

■Exterior Checks1Exterior Checks
NOTICE
When doors are frozen s hut, use warm water around
the door edges to melt any ice. Do not try to force
them open, as this can damage the rubber trim
around the doors. When done, wipe dry to avoid
further freezing.
Do not pour warm water into the key cylinder.
You will be unable to insert the key if the water
freezes in the hole.
Heat from the engine and exhaust can ignite
flammable material s left under the hood, causing a
fire. If you’ve parked y our vehicle for an extended
period, inspect and remove any debris that may have
collected, such as dried grass and leaves that have
fallen or have been carried in for use as a nest by a
small animal. Also check under the hood for leftover
flammable materials after you or someone else has
performed maintenance on your vehicle.
