Vehicle Care 10-33
Headlamp Aiming
The vehicle may have a visual
optical headlamp aiming system.
The aim has been preset at the
factory and should need no further
adjustment.
However, if the vehicle is damaged
in a crash, the headlamp aim may
be affected and adjustment may be
necessary.
If oncoming vehicles flash their high
beams at you, this may also mean
the vertical aim needs to be
adjusted.
It is recommended that the vehicle
is taken to your dealer for service if
the headlamps need to be re-aimed.
It is possible however, to re-aim the
headlamps as described.The vehicle should be:.Placed so the headlamps are
7.6 m (25 ft) from a light colored
wall or other flat surface.
.On a level surface which is level
all the way to a wall.
.Placed so it is at a right angle to
the wall or other flat surface.
.Clear of any snow, ice, or mud
on it.
.Fully assembled, the tires
properly inflated, and all other
work stopped while headlamp
aiming is being performed.
.Normally loaded with the spare
tire in its original location and a
full tank of fuel and one person
or 75 kg (160 lbs) sitting on the
driver seat.To adjust the vertical aim:
1. Open the hood. See
Hood
on
page 10‑5.
2. Record the distance from the ground to the aim dot on the
headlamp.

10-54 Vehicle Care
If the warning light comes on,
stop as soon as possible and
inflate the tires to the recommended
pressure shown on the tire loading
information label. SeeVehicle Load
Limits on page 9‑27.
At the same time, a Driver
Information Center (DIC) message
is displayed on the DIC display
screen. The low tire pressure
warning light and the DIC warning
message come on at each ignition
cycle until the tires are inflated to
the correct inflation pressure. For
additional information and details
about the DIC operation and
displays see Tire Messages
on
page 5‑25.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as you start to drive. This
could be an early indicator that the
air pressure in the tire(s) are getting
low and need to be inflated to the
proper pressure. A Tire and Loading Information
label, attached to the vehicle, shows
the size of the vehicle's original
equipment tires and the correct
inflation pressure for the vehicle's
tires when they are cold. See
Vehicle Load Limits
on page 9‑27,
for an example of the Tire and
Loading Information label and its
location on the vehicle. Also see
Tire Pressure on page 10‑51.
The vehicle's TPMS can warn you
about a low tire pressure condition
but it does not replace normal tire
maintenance. See Tire Inspection
on page 10‑57,Tire Rotationon
page 10‑57and Tires on
page 10‑44.
Notice: Liquid tire sealants could
damage the Tire Pressure Monitor
System (TPMS) sensors. Sensor
damage caused by using a tire
sealant is not covered by your
warranty. Do not use liquid tire
sealants.
TPMS Malfunction Light and
Message
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
system detects a malfunction, the
low tire warning light flashes for
about one minute and then stays on
for the remainder of the ignition
cycle. A DIC warning message is
also displayed. The low tire warning
light and DIC warning message
come on at each ignition cycle until
the problem is corrected. Some of
the conditions that can cause the
malfunction light and DIC message
to come on are:
.One of the road tires has been
replaced with the spare tire.
The spare tire does not have
a TPMS sensor. The TPMS
malfunction light and DIC
message should go off once you
re‐install the road tire containing
the TPMS sensor.

4. Locate the vehicle's jacking positions (A and B). 5. Assemble the jack and tools as
follows:
Front Position
Front Tire Flat: If the flat tire
is on a front tire of the vehicle,
use the jack handle and both
jack handle extensions. Attach
the wheel wrench to the jack
handle extensions. Attach
the jack handle to the jack. From the front of the vehicle
position the jack on the front
lower control arm along the bar
that runs front to back. Turn the
wheel wrench clockwise to raise
the vehicle. Raise the vehicle far
enough off the ground so there
is enough room for the spare tire
to clear the ground.
Rear Positions
Refer to the graphic above to
locate the placement of the jack
if the flat tire is on the rear of the
vehicle.

Vehicle Care 10-71
Rear Tire Flat:Use the jack
handle and both jack handle
extensions. Attach the wheel
wrench to the jack extensions.
Attach the jack handle to the
jack. From the rear of the vehicle
align the jack under the rear
axle. Turn the wheel wrench
clockwise to raise the vehicle.
Raise the vehicle far enough off
the ground so there is enough
room for the spare tire to clear
the ground.
6. Turn the wheel wrench clockwise to raise the jack head
to the lifting point.
{WARNING
Getting under a vehicle when it is
jacked up is dangerous. If the
vehicle slips off the jack, you
could be badly injured or killed.
Never get under a vehicle when it
is supported only by a jack.
{WARNING
Raising your vehicle with the
jack improperly positioned can
damage the vehicle and even
make the vehicle fall. To help
avoid personal injury and vehicle
damage, be sure to fit the jack lift
head into the proper location
before raising the vehicle.
7. Remove all the wheel nuts and take off the flat tire.
{WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, use a cloth or a
paper towel to do this; but be sure
to use a scraper or wire brush
later, if needed, to get all the rust
or dirt off. See If a Tire Goes Flat
on page 10‑64.
8. Remove any rust or dirt from the wheel bolts, mounting surfaces
and spare wheel.
