Information Displays

Vehicle information and general safety
practices:
• Know the make and model of your
vehicle.
• Review the owner’s manual and become
familiar with your vehicle’s safety
information and recommended safety
practices.
• Do not attempt to repair damaged
electric and hybrid-electric vehicles
yourself.
Contact an authorized dealer.Crashes
A crash or impact significant enough to
require an emergency response for
conventional vehicles would also require the
same response for an electric or
hybrid-electric vehicle.
If possible:
• Move your vehicle to a safe, nearby
location and remain on the scene.
• Roll down the windows before switching
your vehicle off.
• Place your vehicle in park (P), set the
parking brake, switch off the vehicle,
activate the hazard warning flashers and
move your key(s) at least 15 ft (5 m) away
from the vehicle.
Always:
• Call emergency assistance if needed and
advise that an electric or hybrid-electric
vehicle is involved.
• Exposed electrical components, wires,
and high-voltage batteries present
potential high-voltage shock hazards.• Avoid contact with leaking fluids and
gases, and remain out of the way of
oncoming traffic until emergency
responders arrive.
• When emergency responders arrive, tell
them that the vehicle involved is an
electric vehicle or hybrid-electric vehicle.
Fires
As with any vehicle, call emergency
assistance immediately if you see sparks,
smoke or flames coming from the vehicle.
Remain a safe distance from the vehicle and
try to stay clear of the smoke.
• Exit the vehicle immediately.
• Advise emergency assistance that an
electric or hybrid-electric vehicle is
involved.
• As with any vehicle fire, do not inhale
smoke, vapors or gas from the vehicle,
as they may be hazardous.
• Stay out of the roadway and stay out of
the way of any oncoming traffic while
awaiting the arrival of emergency
responders.

ENGINE OIL CHECK
1. Make sure that your vehicle is on level
ground.
2. Check the oil before starting the engine
or switch the engine off and wait 10
minutes for the oil to drain into the oil
pan.
3. Remove the dipstick and wipe it with a
clean, lint-free cloth.
4. Reinstall the dipstick and make sure it is
fully seated. Remove it again to check
the oil level.
5. If the oil level is between the maximum
and minimum marks, the oil level is
acceptable. Do not add oil.6. If the oil level is at the minimum mark,
immediately add oil.
7. Reinstall the dipstick. Make sure it is fully
seated.
Note:The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km).
Adding Engine Oil
WARNING: Do not remove the filler
cap when the engine is running.
WARNING: Do not add engine oil
when the engine is hot. Failure to follow
this instruction could result in personal
injury.

Maintenance

If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long or
steep grade in high ambient temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.
You may notice a reduction in vehicle speed
caused by reduced engine power in order
to manage the engine coolant temperature.
Your vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on vehicle loading, grade and
ambient temperature. If this occurs, there is
no need to stop your vehicle. You can
continue to drive.
The air conditioning may automatically turn
on and off during severe operating
conditions to protect the engine from
overheating. When the coolant temperature
decreases to the normal operating
temperature, the air conditioning turns on.If the coolant temperature gauge moves fully
into the red zone, or if the coolant
temperature warning or service engine soon
messages appear in your information display,
do the following:
1. Stop your vehicle as soon as it is safe to
do so. Fully apply the parking brake, shift
into park (P) or neutral (N).
2. Leave the engine running until the
coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after several
minutes, follow the remaining steps.
3. Switch the engine off and wait for it to
cool. Check the coolant level.
4. If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the
engine and continue.AUTOMATIC TRANSMISSION
FLUID CHECK
If required, have an authorized dealer check
and change the transmission fluid at the
correct service interval. See Scheduled
Maintenance (page 579).
The automatic transmission does not have
a transmission fluid dipstick.
Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission does
not consume fluid. However, if the
transmission slips, shifts slowly or if you
notice a sign of leaking fluid, contact an
authorized dealer.
Do not use supplemental transmission fluid
additives, treatments or cleaning agents. The
use of these materials may affect
transmission operation and result in damage
to internal transmission components.
