MAINTENANCE PRECAUTIONS
Have your vehicle serviced regularly to help
maintain its roadworthiness and resale
value. There is a large network of
authorized dealers that are there to help
you with their professional servicing
expertise. We believe that their specially
trained technicians are best qualified to
service your vehicle properly and expertly.
They are supported by a wide range of
highly specialized tools developed
specifically for servicing your vehicle.
If your vehicle requires professional service,
an authorized dealer can provide the
necessary parts and service. Check your
warranty information to find out which
parts and services are covered.
Use only recommended fluids and service
parts conforming to specifications. See
Capacities and Specifications (page
344).

Note: Some of these components are

removed. See
Installing and Removing

277).
CHECKING THE COOLANT WARNING:
Do not remove the
coolant reservoir cap when the vehicle
is on or the cooling system is hot. Wait
10 minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury. WARNING:
Do not put coolant in
the windshield washer reservoir. If
sprayed on the windshield, coolant could
make it difficult to see through the
windshield. WARNING:
Do not add coolant
further than the MAX mark.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
Your vehicle has a battery cooling system
and a motor electrical cooling system. See
Under Hood Overview
(page 303). The
luggage compartment covers need to be
removed in order to access the reservoirs.
See
Installing and Removing the
Luggage Compartment Cover (page 277). When the electric motor is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 390).
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between
-29–-35°F (-34–-37°C).
Check coolant concentration using a
refractometer. We do not recommend the
use of hydrometers or coolant test strips
for measuring coolant concentration.
Adding Coolant
It is very important to use prediluted
coolant approved to the correct
specification in order to avoid plugging the
small passageways in the electric motor
cooling system. See
Cooling System
Capacity and Specification (page 344).
Do not mix different colors or types of
coolant in your vehicle. Mixing of coolants
or using an incorrect coolant may harm the
electric motor or cooling system
components and may cause damage that
the vehicle warranty may not cover.
Note: Automotive fluids are not
interchangeable.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the electric
motor cooling or heating systems.

properly aimed at the assembly plant. If
your vehicle has been in an accident, have
the alignment of your headlamps checked
by an authorized dealer.

Vertical Aim Adjustment
1. Park your vehicle on a level surface approximately 25 ft (7.6 m) away from
a vertical wall or screen.
2. Apply the parking brake.
3. Measure the height from the center of your headlamp to the ground.
Note: There may be an identifying mark on
the lens to help you locate the center of the
headlamp low beam light.
4. Mark a horizontal reference line on the
wall or screen that is a minimum of 8 ft
(2.4 m)

6. On the wall or screen you will observe
a flat zone of high intensity light
located at the top of the right hand
portion of the beam pattern. If the top
edge of the high intensity light zone is
not at the horizontal reference line, the
headlamp will need to be adjusted.
Note: To see a clearer light pattern while
adjusting one headlamp, block the light
from the other headlamp. 7. Locate the vertical adjuster on each
headlamp. Use a Phillips #2
screwdriver to turn the adjuster either
clockwise or counterclockwise to
adjust the vertical aim of the
headlamp.
8. Repeat Steps 3 through 7 to adjust the
other headlamp.
9. Close the hood and turn off the lamps.

PREPARING YOUR VEHICLE
FOR STORAGE
If you plan on storing your vehicle for 30
days or more, read the following
maintenance recommendations to make
sure your vehicle stays in good operating
condition.
We engineer and test all vehicles and their
components for reliable, regular driving.
Under various conditions, long-term
storage may lead to degraded
performance or failure unless you use
specific precautions to preserve vehicle
components.
General
•
Store all vehicles in a dry, ventilated
place.
• Protect from sunlight, if possible.
• If vehicles are stored outside, they
require regular maintenance to protect
against rust and damage.
Body
• Wash your vehicle thoroughly to
remove dirt, grease, oil, tar or mud from
exterior surfaces, rear-wheel housing
and the underside of front fenders.
• Periodically wash your vehicle if it is
stored in exposed locations.
• Touch-up exposed or primed metal to
prevent rust.
• Cover chrome and stainless steel parts
with a thick coat of auto wax to prevent
discoloration. Re-wax as necessary
when you wash your vehicle.
• Lubricate all hood, door and luggage
compartment hinges and latches with
a light grade oil.
• Cover interior trim to prevent fading.
• Keep all rubber parts free from oil and
solvents. Cooling system
•
Protect against freezing temperatures.
• When removing your vehicle from
storage, check coolant fluid level.
Confirm that there are no cooling
system leaks and that fluid is at the
recommended level.
Battery Systems
We recommend the following actions for
your vehicle:
• When storing your vehicle for greater
than 30 days the state of charge
should be approximately 50%.
Additionally we recommend
disconnecting the 12v battery which
will reduce system loads on the HV
battery.
Brakes
• Make sure the brakes and parking brake
release fully.
Tires
• Maintain recommended air pressure.
Miscellaneous
• Make sure all linkages, cables, levers
and pins under your vehicle are covered
with grease to prevent rust.
• Move vehicles at least 25 ft (7.5 m)
every 15 days to lubricate working parts
and prevent corrosion.
