Warning (Continued)
death, or vehicle damage. Before making
a lane change, always check mirrors,
glance over your shoulder, and use the
turn signals.
SBZA Detection Zones
The SBZA sensor covers a zone
approximately one lane over from both
sides of the vehicle, or approximately
3.5 m (11 ft). The height of the zone is
approximately between 0.5 m (1.5 ft) and
2 m (6 ft) off the ground. This zone starts at
approximately the middle of the vehicle and
goes back 5 m (16 ft).
How the System Works
The SBZA symbol lights up in the side
mirrors when the system detects a moving
vehicle in the next lane over that is in the
side blind zone. This indicates it may be
unsafe to change lanes. Before making a
lane change, check the SBZA display, check
mirrors, glance over your shoulder, and use
the turn signals.
Left Side Mirror DisplayRight Side Mirror Display
When the vehicle is started, both outside
mirror SBZA displays will briefly come on to
indicate the system is operating. When the
vehicle is in a forward gear, the left- or
right-side mirror display will light up if a
moving vehicle is detected in that blind
zone. If the turn signal is activated in the
same direction as a detected vehicle, this
display will flash as an extra warning not to
change lanes. SBZA can be disabled through vehicle
personalization. To view available settings
from the infotainment screen, touch
Settings > Vehicle > Collision/Detection
Systems. If SBZA is disabled by the driver,
the SBZA mirror displays will not light up.
When the System Does Not Seem to
Work Properly
SBZA displays may not come on when
passing a vehicle quickly, for a stopped
vehicle. SBZA may alert to objects attached
to the vehicle, such as a bicycle, or object
extending out to either side of the vehicle.
This is normal system operation; the vehicle
does not need service.
SBZA may not always alert the driver to
vehicles in the side blind zone, especially in
wet conditions. The system does not need
to be serviced. The system may light up due
to guardrails, signs, trees, shrubs, and other
non-moving objects. This is normal system
operation; the vehicle does not need service.
SBZA may not operate when the SBZA
sensors in the left or right corners of the
rear bumper are covered with mud, dirt,
snow, ice, or slush, or in heavy rainstorms.

{Warning
The engine oil dipstick handle may be
hot; it could burn you. Use a towel or
glove to touch the dipstick handle.
3. Remove the dipstick and wipe it with a clean lint-free paper towel or a cloth.
Re-insert the dipstick and push it all the
way in until it stops.
4. Remove the dipstick again and read the level on the cross-hatched area. Re-insert
the dipstick and push it all the way in
until it stops.
5. Turn the engine off.
When to Add Engine Oil
If the oil is below the cross-hatched area at
the tip of the dipstick, add 1 L (1 qt) of the
recommended oil through the oil fill cap
opening in the oil tank fill tube and then
recheck the level. See “Selecting the Right
Engine Oil” later in this section for the type of oil to use. For engine oil crankcase
capacity, see
Capacities and Specifications
0 315.
Caution
Do not add too much oil. Oil levels above
or below the acceptable operating range
shown on the dipstick are harmful to the
engine. If the oil level is above the
operating range (i.e., the engine has so
much oil that the oil level gets above the
cross-hatched area that shows the proper
operating range), the engine could be
damaged. Drain the excess oil or limit
driving of the vehicle, and seek a service
professional to remove the excess oil.
See Engine Compartment Overview 0235 for
the location of the external engine oil tank
dipstick and fill cap.
Add enough oil to put the level somewhere
in the proper operating range. Push the
dipstick all the way back into the oil tank
tube when finished.
Changing the Engine Oil and Filter
The vehicle requires a special procedure
when changing the engine oil and filter.
