Introduction

While a vehicle is in inventory, the battery is subject to conditions that can reduce its performance
and life. Batteries can become discharged due to an extended storage period, temperature, parasitic
drain, or while demonstrating vehicle features and benefits in the sales process. Battery inspection
and maintenance are required in order to ensure proper operation and optimal battery life.

Recommended Battery Maintenance Procedures

In addition to the Pre-Delivery Service battery test, a monthly battery inspection is required for stored
vehicles. If your dealership is located in an area subject to extreme temperatures (hot or cold),
periodic maintenance may need to be performed more frequently.

As a matter of policy, Lexus does not provide battery warranty coverage for discharged and/or
failed batteries due to lack of maintenance. It is the dealership's responsibility to maintain the
specified State of Charge (SOC) of the vehicle's battery while in stock and assure proper State of
Charge (SOC) at delivery.

NOTE

To eliminate customer service concerns due to an undercharged battery during the first few weeks
of ownership, all dealers should check battery State of Charge (SOC) and recharge with the GR8
Battery Diagnostic Station, if necessary, within 48 hours of delivery to customers.

Battery Maintenance for In-Stock Vehicles

Recommended Battery Maintenance Procedures (Continued)
Method 1: Starting Engine
Under this method, vehicles are started after 60 days in inventory, and then every 30 days after that

CAUTION

Be sure to secure the vehicle and consider if the vehicle's location is safe to perform this process.
It may be necessary to relocate the vehicle and monitor it to ensure safety.

Overview of Method 1:
* Car arrives at dealership.
* Car is in inventory for 60 days. Run engine for 30 minutes with all accessories off.

* At 30-day intervals, continue to start and run engine for 30 minutes, with all accessories off, until
car is sold and delivered.

NOTE

+ Even if the vehicle has been moved or “staged” around while in inventory, this procedure stil!
applies. The storage age should consider time spent at your dealership, and in addition, time
spent at a different dealership for dealer trades.

* This procedure and Service Bulletin should be shared with the sales department, as at most
dealerships the sales department is responsible for the vehicles.

1. Is the vehicle’s age in inventory equal to or at least 60 days, or has 30 days elapsed since the
first time it was run (at 60 days)?

+ YES — Continue to step 2.

* NO— Monitor the vehicle's age until it equals 60 days initial age in inventory, or 30-day
intervals after that, then proceed to step 2.

2. Attempt to start the vehicle.

* If the vehicle starts normally and does not indicate signs of a discharged battery, then turn
OFF all accessories and power draws and proceed to step 3.

+ Ifthe vehicle exhibits signs of discharged battery or slow crank, go to step 4. Otherwise, go
to step 3.

NOTE
This step should be repeated every 30 days after the initial 60 days until the vehicle is sold
and delivered.
