The system has three alert stages for a possible collis ion. However, depending on circumstances, the CMBSTM may not go through all of 
the stages before initiating the last stage.

Driving
The system may automatically shut off and the CMBSTM indicator will come on under 
certain conditions. Some examples of th ese conditions are listed below. Other 
conditions may reduce some of the CMBS
TM functions.
2 Front Sensor Camera  P. 400
■Environmental conditions
• Driving in bad weather (rain, fog, snow, etc.).
• Sudden changes between light and dark, such as an entrance or exit of a tunnel.
• There is little contrast between objects and the background.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflected onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Roadway objects or structures are misint erpreted as vehicles and pedestrians.
• Reflections on the interi or of the windshield.
• Driving at night or in a dark condition such as a tunnel.
■Roadway conditions
• Driving on a snowy or wet roadway (obs cured lane marking, vehicle tracks, 
reflected lights, road  spray, high contrast).
• Driving on curvy, winding, or undulating roads.
• The road is hilly or the vehicle is approaching the crest of a hill.
■CMBSTM Conditions and Limitations1CMBSTM Conditions and Limitations
Do not paint, or apply any coverings or paint to the 
radar sensor  area. This can impact CMBS
TM operation.
Have your vehicle checked by a dealer if you find any 
unusual behavior of the system (e.g., the warning 
message appears too frequently).
If the front of the vehicle  is impacted in any of the 
following situations, the ra dar sensor may not work 
properly. Have your vehi cle checked by a dealer:
•The vehicle mounted onto a bump, curb, chock, 
embankment, etc.
•You drive the vehicle where the water is deep.
•Your vehicle has a frontal collision.
If you need the radar sensor to be repaired, or 
removed, or the radar se nsor cover is strongly 
impacted, turn off the system by pressing the 
CMBS
TM OFF button and take your vehicle to a 
dealer.

Replacing the Button Battery
If the indicator does not come on when the button is pressed, replace the battery.
1.Remove the built-in key.
u As a convenience, lightly place masking 
tape over the remote  buttons to hold 
them in place.
2. Remove the upper half by carefully prying 
on the edge with a coin.
u Wrap a coin with a cloth to prevent 
scratching the transmitter.
3. Press down on the center of the assembly 
and remove the battery.
u When removing the button battery, be 
careful not to touch parts around it.
4. Make sure to replace  the battery with the 
correct polarity.1 Replacing the Button Battery
NOTICE
An improperly disposed of  battery can damage the 
environment. Always conf irm local regulations for 
battery disposal.
NOTICE
The Remote transmitter  is equipped with two 
batteries: A standard  replaceable CR2032 coin 
button battery and an in tegral non-replaceable 
rechargeable battery. To prevent permanent damage 
to the rechargeable battery, replace the CR2032 
battery every three to four years.
Replacement batteries are commercially available or 
at a dealer.
3WARNING
CHEMICAL BURN HAZARD
The battery that powers the remote 
transmitter can cause severe internal burns 
and can even lead to  death if swallowed.
Keep new and used batteries away from 
children.
If you suspect that a child has swallowed 
the battery, seek medical attention 
immediately.

If a Tire Goes Flat
Temporarily Repairing a Flat Tire
If the tire has a large cut or is otherwise severely damaged, you will need to have the 
vehicle towed. If the tire only has a small puncture, from a nail for instance, you can 
use the temporary tire repair kit so that  you can drive to the nearest service station 
for a more permanent repair.
If a tire goes flat while driving, grasp  the steering wheel firmly, and brake gradually 
to reduce speed. Then stop in a safe place.
1. Park the vehicle on a firm, level, and n on-slippery surface and apply the parking 
brake.
2. Change the gear position to

3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF.
1Temporarily Repairing a Flat Tire
NOTICE
Do not use a puncture-repairing agent other than the 
one provided in the kit that  came with your vehicle. If 
a different agent is used, you may permanently 
damage the tire pressure sensor.
The kit should not be used in  the following situations. 
Instead, contact a dealer or a roadside assistant to 
have the vehicle towed.
•The tire sealant has expired.•More than one tire is punctured.•The puncture or cut is larger than 3/16 inch (4 mm).•The tire side wall is da maged or the puncture is 
outside the contact area.
•Damage has been caused by  driving with the tire 
extremely under inflated.
•The tire bead is no longer seated.•The rim is damaged.
Do not remove a nail or  screw that punctured the 
tire. If you remove it from  the tire, you may not be 
able to repair the puncture using the kit.

Changing a Flat Tire
If a tire goes flat while driving, grasp  the steering wheel firmly, and brake gradually 
to reduce speed. Then, stop in a safe plac e. Replace the flat tire with a compact 
spare tire. Go to a dealer as soon as possib le to have the full-size tire repaired or 
replaced.
1. Park the vehicle on firm, level, and non-slippery surface, and apply the parking 
brake.
2. Change the gear position to

1Changing a Flat Tire
NOTICE
Do not use an unapproved puncture-repairing agent 
on a flat tire, as it can damage the tire pressure 
sensor.
NOTICE
Do not use the jack if it  doesn’t work properly. Call 
your dealer or a prof essional towing service.
Follow compact spare precautions:
Periodically check the tire pressure of the compact 
spare. It should be set to the specified pressure. 
Specified Pressure: 60 psi (420 kPa, 4.2 kgf/cm
2)
When driving with the compact spare tire, keep the 
vehicle speed under 50 mph (80 km/h). Replace with 
a full-size tire as soon as possible.
The compact spare tire and wheel in your vehicle are 
specifically for this model. Do not use them with 
another vehicle. Do not us e another type of compact 
spare tire or wheel with your vehicle.
Do not mount tire chains  on a compact spare tire.
If a chain-mounted front tire  goes flat, remove one of 
the full-size rear tires and replace it with the compact 
spare tire. Remove the flat front tire and replace it 
with the full-size tire that was removed from the rear. 
Mount the tire chains on the front tire.

cable to the booster battery  + terminal.
u If you use a booster battery, only use a 
12-volt booster battery.
u When using an automotive battery 
charger, select a charging voltage lower 
than 15-volts. Check the charger manual 
for the proper setting.
4. Connect the second jumper cable to the 
booster battery  - terminal.
■Jump Starting Procedure1Jump Starting
Securely attach the jumper cable clips so that they do 
not come off when the engine vibrates. Also be 
careful not to tangle the ju mper cables or allow the 
cable ends to touch each other while attaching or 
detaching the jumper cables.
Battery performance degrades  in cold conditions and 
may prevent the engi ne from starting.
3WARNING
A 12-volt battery can explode if you do not 
follow the correct procedure, seriously 
injuring anyone nearby.
Keep all sparks, open flames, and smoking
